Abstract: The impact of seed rate (100, 120 and 140 kg ha-1) and seed invigoration treatments (control, hydro-priming for 18 hrs at 20°C, GA3 priming at 500 ppm GA3 solution for 18 hrs at 20°C, low temperature hardening for 18 hrs followed by chilling temperature (5 ±2°C) for 24 hrs and osmo-priming at -3 bar solution of PEG-6000 for 96 hrs at 20°C) on crop performance were evaluated under late sown wheat. Initial plant population (m-2) improved significantly with increase in seed rate. Seed rate of 120 kg ha-1 showed the earliest emergence and first tiller formation. It was significantly superior to 140 kg seed ha-1 and at par with 100 kg seed ha-1.Similarly more leaf area (cm2 shoot-1) and leaf dry weight (mg shoot-1) was observed with 120 kg of seed rate. Higher seed rate improved LAI at 90 day after sowing than that of lower seed ha-1. In case of priming treatments, low temperature hardening increases the speed and uniformity of emergence and first tiller formation than non primed seed. In low temperature hardening plant population also increased by 11.2 % over control seed. There was no effect of invigoration treatments on leaf area at 100 DAS. Significantly highest LAI was observed with control at 90 days after sowing which was significantly at par with hydro-priming and osmo-priming. No significant variation was recorded in grains spike-1, number of productive shoots and grain yield due to different seed rate and priming treatments.

Key words: Wheat, seed invigoration, seed rate, low temperature stress.

Abstract:We propose an improved method of recording of the spectra of micro- and nanopowders under repetitively pulsed laser excitation. The newly developed laser source is capable nondestructive heating of substances providing the possibility of multiple measurements without damage of the sample. Isochronous secondary radiation spectra of a number of aromatic powders are studied and relaxation times of the corresponding electron terms are calculated. Using pulse-periodic excitation and the time delay settings in the registration system allowed us to study the conditions of the emergence and separation of “fast” and “slow” components of the secondary radiation of the structures under study. The developed method provides information even with small amounts of the sample.

Abstract:The present experiment was carried out with sweet potato cv. NDSP-65 in randomized block design with three replications during 2012-13. The experiment comprised of ten different treatment combinations. T1 (Recommended dose of fertilizer (NPK) @50:25:50kg/ha), T2 (RDF (NPK) + 1t/ha Neem cake), T3 (RDF (NPK) + 2t/ha Neem cake), T4 (RDF (NPK) + 3t/ha Neem cake), T5 (FYM @ 10t/ha + RDF + 1t/ha Neem cake), T6 (FYM @ 10t/ha + RDF + 2t/ha Neem cake), T7 (FYM @ 10t/ha + RDF +3t/ha Neem cake), T8(FYM @ 5t/ha + RDF + 1t/ha Neem cake), T9 (FYM @ 5t/ha + RDF + 2t/ha Neem cake) and T10 (FYM @ 5t/ha + RDF + 3t/ha Neem cake). The experimental findings evident that the use of T7 (FYM @ 10t/ha + RDF +3t/ha Neem cake) was found better with respect to promotion of growth, yield and quality parameters of sweet potato. The maximum values on growth characters were recorded by the use of FYM @ 10t/ha + RDF +3t/ha Neem cake (T7). T7 (FYM @ 10t/ha + RDF +3t/ha Neem cake) was found to be most useful in connection with promotion of all yield attributes which recorded highest yield i.e. 261.92 q/ha. However, maximum net return Rs.168279 as well as benefit: cost ratio (3.07) was obtained under treatments T8(FYM @ 5t/ha + RDF + 1t/ha Neem cake)was found to be most remunerative treatment and help in taking decision for successful crop production of sweet potato from farmer’s point of view.

Abstract: Imphal-East District of Manipur was selected purposively for present study. Based on the maximum area cultivated under hybrid rice, Keirao Bitra block was selected purposively. Total a sample size of 106 respondents were selected through Complete Survey method. The collected data were subjected for analyzing by using appropriate statistical tools namely, frequency, percentage, mean, standard deviation simple correlation coefficient and multiple regressions. 27.36 per cent of the respondents showed no gap in seed rate by adopting the recommended seed rate. However, majority of the respondents (72.64%) was found in the partial gap. Majority of the respondents were51.89 per cent showed partial gap in timely nursery rising. 68.87 per cent of the respondents were found in full gap in adoption of plant protection in nursery. Majority of the respondents (66.04%) were found under partial gap in timely transplanting. Majority of the respondents (54.72%) were found under no gap in the use of recommended nitrogen fertilizer dose. The uses of phosphorus fertilizer by majority of the respondents (66.04%) were found under partial gap in the using of recommended phosphorus fertilizer. Majority of the respondents (62.26%) showed partial gap in the use of recommended potassic fertilizer dose. majority of the respondents (71.70%) belonged to medium category of technological gap followed by low level of technological gap (25.47%). Only (2.83%) of the respondents had high extent of technological gap. This indicates that majority of the farmers where in partial gap due to lack of complete knowledge and information about the recommended practices in hybrid rice cultivation technology.

Abstract: The results revealed that the maximum number of siliquae plant-1, length of siliqua, number of seeds siliqua-1, harvest index and oil content were recorded with application sulphur of 60 kg ha-1 which was significantly over rest of treatments. However, 1000-seed weight, biological yield, seed yield, stover yield and protein content were significantly increased with increasing doses of sulphur upto 40 kg ha-1. Among different genotypes, Varuna’ gave higher siliquae plant-1, siliqua length, seed siliqua-1, seed yield plant-1 and 1000 seed weight which was significantly superior over rest of genotypes. Varuna also gave highest net return and benefit cost ratio (1.7). Among levels of sulphur, the net returns increased with the increase in sulphur dose up to 40 kg ha-1. higher oil content in seed was recorded with the application of 60 kg S ha-1, which was significantly superior over control and at par with 40 kg S ha-1. This was probably due to the facts that the sulphur is a constituent of lipids and it is also essential for the synthesis of lipids. Based on cost analysis, ‘Varuna’ gave the maximum net returns (Rs 24,081 ha-1), followed by ‘Ashirwad’ (Rs 19814 ha-1). This may be because of higher yield of component varieties. Among levels of sulphur, the net returns increased with the increase in sulphur dose up to 40 kg ha-1. The highest net returns of Rs 17,372 ha-1 was recorded at 40 kg S ha-1, being 122.0 and 35 % higher than that at 0 and 20 kg S ha-1.

Abstract: The mode of inheritance of resistance to bacterial leaf blight was studied in six generations of cross HUR-105 X IRBB-55. The resistance cultivar IRBB-55 showed 4.4% disease severity, while susceptible cultivar HUR-105 showed 52.80% disease severity against Xanthomonas oryzae pv. oryzae. The area under the disease progress curve of resistance cultivar was 47.60 which are significantly less than the susceptible cultivar 614.06. The F1 plants were observed to be resistant with average disease severity 08.33% and AUDPC 82.81. The F2 populations were phenotypically classified into three distinct classes as resistant or moderately resistance, moderately susceptible and susceptible in the ratio 12:3:1, which is mainly due to dominant effects of resistant genes Xa21. The B1 and B2 populations were classified in to two distinct classes as resistant (resistant/ moderately resistant) and susceptible (moderately susceptible/ susceptible) in the ratio 1:1. The their chi square value for F2, B1 and B2 populations were 3.38, 2.82 and 3.42 which is non-significant at 5% level of significance indicating that observed data are in accordance with expected ratio and follow Mendelian pattern of inheritance to bacterial leaf blight in B1 and B2 generations but modification in the F2 populations, it showed masking gene action due to presence of dominant effects of resistant gene Xa21.

Abstract: Associations among grain yield and eleven biometrical quantitative traits were studied under saline-alkaline condition in forty five hybrids of rice. Results revealed that grain yield had a highly significant and negative correlation with days to 50% flowering and days to maturity, indicating suitable for crop rotation. The grain yield/plant was found to be associated positively and significantly at both phenotypic and genotypic leveles with biological yield/plant. The perusal of the data reflected that certain traits were inter correlated among themselves viz; days to 50% flowering, with days to maturity and 1000-grain weight; 1000-grain weight with days to maturity and plant height. Path coefficient at phenotypiclevel reflectedhighest direct positive effect on grain yield with biological yield per plant followed by harvest index while at genotypic level, biological yield per plant had highest direct positive effect on grain yield per plant followed by harvest index. These direct and /or indirect contributors may be selected to enhance the production and productivity ofrice under saline-alkaline condition.

Abstract: Fly ash, the tarnished waste product of coal based thermal power plants and familiar for its ailing effects on agricultural land, may now provide the farming community. These coal and lignite fly ash are equally performed as a fine carrier for bio pesticides. In addition to supply of nutrients from fly-ash with bio-solids may enhance their agricultural use. Thus, use of fly ash is an effectual way of utilization of problematical fly-ash waste in a productive manner. However, several studies anticipated that fly ash could be used to improve physical, chemical and biological properties of the degraded soils and are a source of easily available and cheaper micro, macro-nutrients for crops. Fly ash is exploited as a conditioner to seize soil erosion and to induce plant resistance against diseases. The aim of this review was to provide valuable information on beneficial use of fly ash based pesticide for agricultural purpose. In this review was also covers the sources, merits and applications of fly ash based pesticides and fertilizers in agricultural perspective.

Abstract: Combining ability is the capacity of an individual to transmit superior performance to its offspring. Combining ability of line or inbred is important factor in determining future usefulness of the lines for developing hybrids. The analysis of general and specific combining ability helps in identifying potential parents or inbreds for production of superior hybrids. General and specific combining ability effects were estimated for twelve parents and their 32 hybrids. The results of the present investigation on combining ability effects revealed that parent DSMR-10 exhibited significant gca effects for most of the characters viz., lint yield (kg ha-1),number of boll per plant,boll weight (g), sympodial length at 50 per cent plant height (cm), ginning outturn (%). Hence it was considered as good general combiner. The parent DSG3-5 exhibited significant gca effect for number of bolls per plant and reproductive points on sympodia. The parent DRGR-257 exhibited significant gca effect for Lint yield.DRGR-24-178 exhibited significant gca effect for boll weight, reproductive points on sympodia and plant height. The parent DRGR-32-100 recorded significant gca effect for plant height and number of monopodia per plant.As regardsspecific combining ability effects, it was observed that, the cross DSMR-10 x DSG3-5 and DRGR-24-178 x DRGR-32-100 recorded significant sca effects for number of bolls per plant and boll weight (g). Likewise other crosses also revealed significant sca effects for some yield components traits which confirmed the role of non-additive effects in governing inheritance of these quantitative characters. The results also revealed the crosses of stay greenand robust with high RGR-types were found to be superior and this confirms the heterotic pattern between stay green, robust Vs high RGR-groups.

Abstract: Phomopsis blight of brinjal caused by Phomopsis vexans is an important disease of eggplant inflicting heavy losses. The present study was carried out in poly house of Department of Mycology and Plant Pathology, BHU, Varanasi to study the plant growth promotion activity of phyllospheric isolates against phomopsis blight of egg plant (Solanum melongena L.) caused by Phomopsis vexans. All the growth parameters were significantly influenced by the phyllospheric isolates. Among all the isolates, F4 performed well in controlling fruit rot by enhancing the root growth, shoot growth, number of leaves and chlorophyll content at 45th day. Maximum dry weight of egg plant was obtained with the application of F2 isolate and highest carotenoid was noted with the spray of F1 isolate. However, it can be concluded from molecular and biochemical characterization that F4 performed better over other isolates in inhibiting the fruit rot in brinjal.

Abstract: Wheat (Triticum aestivum L.), continues to be the most dynamic sector in world grain production, grown as staple food crop, constitute the major sources of energy and nutrition of Indian diet. The production of wheat during 2012-13 was 92.46 mt. in the area of 29.65 m/ha and productivity 3.12t/ha. Uttar Pradesh, having the maximum area 9.13m/ha, production 30.30mt, contributes 32.77% of countries production. The national productivity (3.14 t/ha) is very much low as compared to countries like Germany (7.52t/ha), United Kingdom (7.34 t/ha) and Denmark (7.29 t/ha).Disease like rusts, foliar blight, loose smut, karnal bunt, black point and ear cockle are the bottlenecks in achieving the full potential. Black point caused by various fungal pathogens is considered asminor disease, affects the grain as well as seed quality but its importance in global context can be imagined with the fact that according to theU.S. grain standards only upto 2 per cent damaged grain are permitted in wheat grade as U.S. No.1 and 4 per cent U.S. No.2.The disease is responsible for reduced market price and dockage by the elevator.

Abstract: The experiment was conducted to study the effect of different levels of pruning and foliar feeding of nutrients on yield and quality of phalsa (Grewia subinaequalis D.C.). The pruning level at 50 cm above ground level had significantly maximum weight of fifty fruits (44.20 g) and fruit yield per plant (3.82 kg). Moreover, total soluble solids (26.15B) and ascorbic acid (34.64mg/100g pulp) were also recorded high with pruning at 50 cm above ground level. While, highest acidity (2.17%) was noted with pruning at 75 cm above ground level. Regardless of severity of pruning, application of ZnSO4 (0.4%) showed significantly maximum weight of fifty fruits (45.56 g) and fruit yield per plant (3.82 kg). All quality parameters viz., TSS (27.60ÚB), ascorbic acid (36.59mg/100g pulp) and acidity were better with ZnSO4 (0.4%) treatment along with 50 cm pruning above ground level closely.

Abstract: Iron deficiency is extremely common and affects one third of the preschool children and one-half of the women of reproductive age in lower income countries. Nutritional iron deficiency is a major health problem in developing countries. According to WHO, around 0.8 million deaths can be attributed to iron deficiency in each year. The only proven way to alleviate iron deficiency is to increase iron intake, either by providing medicinal iron (supplementation) or by adding iron to the diet (fortification). Bread made from refined wheat flour is consumed extensively throughout the world, especially by populations in developing countries. Several countries have passed legislation for the addition of iron and vitamins to wheat flour as a strategy to decrease the high prevalence of iron deficiency. An investigation was carried out to standardize and evaluate Iron Fortified Bread (IFB), carrying different iron fortificants viz., ferrous sulphate, ferrous fumarate and ferrous ascorbate. The iron fortified bread was evaluated for quality characteristics and acceptability. The selected iron fortificants were fortified at different levels (10, 20, 30mg/100g) in bread with the aim of increasing the iron content of the bread. In the present study the 20mg/100g iron fortified bread was highly acceptable compared to10, 20, 30mg/100g.One loaf of iron fortified bread contains 23 mg of iron which was higher compared to control bread (3.2 mg).

Abstract: The soil-site suitability for sesame cultivation was evaluated in coastal area Jamnagar district (Saurashtra region) of Gujarat State. Nine typical pedons and one hundred eighty surface soil samples were evaluated for their suitability to sesame cultivation using limitations method regarding number and intensity of limitations. The soils were found sandy loam to clayey in texture, alkaline in reaction, calcareous in nature and low in organic carbon. Based on limitations methods, the result of study indicates that sesame is marginally suitable (S3) in the soils of pedon P2 (Lithic Ustorthents), P4(Typic Ustochrepts), P5(Vertic Troparthents), P6 (Lithic Ustochrepts) and P9 (Typic Ustochrepts), but currently not suitable (N1) in the soil of pedon P1 (Lithic Troparthents), whereas soil of pedon P3 (Lithic Ustorthents), P7 (Lithic Ustochrepts) and P8 (Lithic Ustorthents) are not suitable (N2) for sesame cultivation for the major limitations like, topography, climate, soil depth, soil fertility and salinity/alkalinity. Results showed that the suitability classes could be improved through soil amelioration measures of correctable limitations (soil depth, topography, organic carbon and soil salinity characteristics).

Abstract: Indian Himalayan Region (IHR) Inhabitants are largely dependent on the biodiversity, which is one of the major sources of livelihood. The relationship of the people with their immediate environment and natural resources has evolved over a long period based on necessities and experiences. The present study recorded 68.52% native species, 17.48% (27.07% of the natives) near endemics and 2.53% (3.93 % of the natives) endemics from Tirthan Wildlife Sanctuary of the total sampled species. Maximum number of native, near endemic and endemic species i.e., 389 spp., 111 spp., and 16 spp., respectively, were recorded in the altitudinal zone 2801-3800m, whereas, maximum non-native species (236) were recorded in the altitudinal zone, 2100m-2800m above msl. In the sampled sites of forest zone, 66.82% species were natives, 17.54% near endemics and 2.40% endemics whereas in the alpine zone, 75.87% species were natives, 26.75% near endemics and 3.07% endemics. ). In most of the areas, thepopulation of native and endemic species is decreasing fast due to high anthropogenicpressures. To assess the loss of such unique biodiversity elements, studies on the assessmentand distribution pattern of native and endemic species in general and at habitat andcommunity level in particular are essentially required. The present study has therefore, been conductedon these lines.

Abstract: Onion (Allium cepa L.) is one of the important bulb crops in india, which plays a major role in supplementing the income of small and marginal farmers of Dewas district of Madhya Pradesh. Traditionally farmers are not growing onion in Kharif season, though there is a ample scope for cultivation of this crop in the district. During Participatory Rural Appraisal (PRA) survey of the villages, farmers & scientist comes to the conclusion that the cultivation of Kharif onion may be more remunerative over traditional crop soybean. In this regard, Krishi Vigyan Kendra Dewas had conducted front line demonstration on Kharif onion for six consecutive years from 2008-09 to 2013-14 in the farmers field at different locations of Dewas district with the objective to explore the possibility of cultivation of this crop. Encouraging result has been found under front line demonstration which revealed that the average yield performance of 120 demonstrated Kharif onion crop in an area of 12 hectares ranged from 184.20 to 217.34 q/ha. The average yield of demonstrations was found to be 194.38 q/ha, whereas for local check, it was 151.48 q/ha. The percentage increase in the yield of onion ranged from 25.70% to 30.78% over local check during the course of study. The farmers have incurred average additional net returns of Rs. 35828 per ha over local check with benefit cost ratio of 5.52 against the local check which recorded 4.58 B:C ratio. Result of front line demonstration has shown that the use of improved variety, improved cultivation practices, proper and need based plant protection measures and proper post harvest management resulted in higher production of Kharif onion. Further study reveals the wide yield and management gaps between demonstration and farmers practice (local check).

Abstract: Correlation and path analysis studies conducted in thirty diverse genotypes of fenugreek with the objective to know association among the characters viz., plant height (cm), number of branches per plant, days taken to 50% flowering, number of pods per plant, length of pod (cm), number of seeds per pod, days to maturity, 1000 seed weight (g), Seed yield per plant (g) and Seed yield (q/ha).Present study revealed that the plant height (cm), number of branches per plant and seed yield per plant were significantly and positively associated with seed yield (q/ha) both at phenotypic as well as genotypic levels. Inter relationship study revealed that for improvement of fenugreek, plant height (cm), number of branches per plant and seed yield per plant to be given due consideration. Path coefficient analysis revealed that seed yield plant and number of branches per plant exhibited greater direct effect on seed yield q/ha at phenotypic level. Whereas, at genotypic level, days to 50 % flowering, length of pod (cm), seed yield per plant had high direct effect on seed yield q/ha. Therefore, these characters appear to be the most important traits for fenugreek improvement programme.

Abstract: Barley (Hordeum vulgare L.) is one of the founder crops of the old world agriculture and was one of the first domesticated cereals. The objective of this study was to estimate the magnitude of genotype x environment interaction and stability for barley grain yield and yield related traits.Sixty four genotypes of newly bred barley lines were studied for genotype x environment interaction and stability among fourteen quantitative characters viz.,days to 50% flowering, days to maturity, number of effective tillers per plant, plant height (cm),peduncle length (cm),spike length (cm), number of grains per spike,1000-grain weight (g), biological yield per plant (g), grain yield per plant (g), harvest-index (%), grain plumpness (%), protein content (%) and amylose content (%).The data recorded on these characters was utilized for estimation of genotype x environment interaction and stability. The genotypes K-762 (20.13g), RD-2624 (19.52g), HUB-211 (19.40g), NDB-1276 (19.10g), NDB-1573 (18.28g), NDB-1503 (18.27g), BH-902 (17.96g) and NDB-1523 (17.73g) produced higher grain yield per plant.Among the genotypes exhibiting higher grain yield per plant, BH-546, BH-902, BH-925, HUB-202, HUB-211, HUB-212, K-603, K-762, K-944, Karan-16, NB-2, NB-3, NDB-1276, NDB-1503, NDB-1519, NDB-1523, NDB-1570, NDB-1573, RD-2552, RD-2624 and RDB-1 possessed bi=1 and S2di=0 while 4 genotypes, NDB-1276, NDB-1450, RD-2035 and RD-2592 had bi>1 and S2di=0.However, 17 genotypes, Azad, BH-75, BH-913, BHS-169, HUB-208, HUB-210, K-141, K-508, K-560, K-792, K-796, NB-1, NDB-1173, NDB-1436, NDB-943, RD-2052 and RD-31 showed average linear response (bi=1) and unstable performance (S2di>0) for grain yield per plant.The eight high yielding genotypes K-762, RD-2624, HUB-211, NDB-1276, NDB-1573, NDB-1503, BH-902 and NDB-1523 merit due consideration for recommending their exploitation as cultivars or varieties for commercial cultivation and/or as donor for hybridization programme for wide range of environments pertaining especially to variable soil types.
