Abstract: Heat stress becomes an important threat for agriculture. The severity of stress is determined by the temperature differential and the duration of exposure. Temporary or persistently higher temperature is responsible for morphological, physiological and biochemical changes in plant species that affect plant growth and development and direct to a severe decline in economic yield. High temperatures can cause considerable pre and post-harvest damages, including scorching of leaves and twigs, sunburns on leaves, branches and stems, leaf senescence and abscission, shoot and root growth inhibition, fruit discoloration and damage, and reduced yield. After that it affects the physiology of photosynthesis, respiration, electron transport system and water relations. It can be mitigated by development of variety enriched with heat sock protein.

Key words: Heat stress, Temperature, Photosynthesis, Heat shock protein

Abstract: Environmental concerns and awareness on soil and human health has led to renewed interest in organic production of high value crops. In view of sustainable productivity and increased demand for quality produce, the organic inputs are the only alternative. The indiscriminate use of chemical fertilizers has led to so many problems although they have played a great role in increasing the yield. In this review, the scattered information on the nature, role and utility of biological inputs in vegetable crop production has been compiled. This may be helpful in enhancing knowledge regarding biological inputs and draw attention of the researchers and scientists to further work on it.

Abstract: In the present paper, an application of discriminant function analysis of meteorological parameters for developing suitable statistical models to forecast on wheat yield in Sultanpur district of Eastern Utter Pradesh has been demonstrated. Time series data on wheat yield for 22 years (1990-91 to 2011-12) have been divided into three groups, viz. congenial, normal, and adverse based on de-trended yield distribution. Considering these groups as three populations, discriminant function analysis using weekly data of crop season on eight meteorological parameters has been carried out. The discriminant scores obtained from this have been used as regressor variables along with time trend in development of statistical models. In all six procedures using weekly weather data have been proposed. The models developed have been used to forecast the wheat yield for the year 2009-10, 2010-11 and 2011-12 which were not included in the development of the models. It has been found that most of the models provide reliable forecast of the wheat yield about two months before the harvest. It can be concluded that the Model-D1 and Model-D3 are the most suitable models among all the models. Hence, a reliable forecast of wheat yield about two and half months before the harvest can be obtained from the Model-D1 as well as Model-D3. In all the models, the time trend variable T has been found to be significant at one percent probability level of significance (P < 0.01). First discriminant score (ds1) has been found to be significant at P < 0.01 in all the models while the model 5 significant at P < 0.05.

Abstract: The genetic parameters were studied to elucidate the genetic variability, heritability and genetic advance in tomato (Solanum lycopersicum L.). Field evaluation of F6 recombinant inbred lines was done. The genotypes exhibited a wide range of variability for all the characters studied. Phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the characters studied. High heritability was observed for the characters Average fruit weight (g) (76.29%), Number of branches per plant (82.29), Number of fruits per plant (84.91), Plant height(cm) (86.87), Fruit yield per plant (kg) (76.87), Total soluble solid (0Brix) (80.10), Number of locules/fruit (77.34) and Pericarp thickness (mm) (73.97). High heritability combined with high genetic advance indicates that additive gene action plays a major role in governing these traits and these traits can be improved by simple selection.

Abstract: In the present investigation screening of five organic amendments viz., mustard cake, neem cake, castor cake, vermicompost and FYM evaluated against Fusarium solani by poisoned food technique, that all of the organic amendments were found significantly effective in inhibiting the radial growth of Fusarium solani in vitro. The inhibition due to different amendements ranged between 3.2 and 13.9 per cent after 240 hrs of incubation. However, among the cakes, highest inhibition of the pathogen was recorded in neemcake (13.9%) followed by mustard cake (13.5%) and castor cake (7.1%) over control.Thus, neem cake was most effective in checking the growth of the pathogen. During evaluation of plant extracts, two different concentrations (8% and 10%) of aqueous extracts of wild garlic, neem, garlic, tulsi and makoi were tested against root rot incidence on papaya under artificial condition in pot. All the plant extracts significantly inhibited the root rot incidence on papaya. The lowest root rot incidence was recorded with wild garlic with 43 per cent and 45 per cent incidence at 10 per cent and 8 per cent concentrations respectively followed by that of neem (47%) incidence and garlic (49%) incidence at their 10 per cent concentration. Among the aqueous plant extracts, wild garlic (Adenocalymma alliaceum) 10 per cent was identified as the most effective plant extract where disease symptom was not observed upto 67 days.

Abstract: Rauvolfia serpentina (L.) Benth. ex Kurz. is a threatened plant species because of extensive utilization for its wide ranging medicinal applications. The roots of R. serpentina are under use in traditional and Modern systems of medicine. The wild population of this valuable medicinal plant is in dwindling stage in the natural habitats due to over exploitation and different anthropogenic activities. R. serpentina can be propagated by both seed and propagules but seed mediated propagation is unsatisfactory due to dormancy and poor germination. Thus efforts were made in this study to break dormancy and improve germination of seeds for boosting conservation. The viability of R. serpentina was found 69%. Germination percentage of treated seeds showed improved germination of 27.5% when treated with H2SO4 for 30 minutes. Scarified seed exhibited 38% germination and the highest germination achieved by Gibberellic acid 300ppm (59.7%) over control which resulted into only 13% germination. Temperature also influenced the germination percentage that was obtained highest at 300C. Results of treatments indicate the presence of coat induced and non-deep physiological dormancy in this species. Due to its potential to cure different diseases it is therefore essential to cultivate this drug yielding plant on large scale for the mass multiplication and production of quality planting material of R. Serpentina.

Abstract: Information on the extent of genetic variability and heritability for important quantitative traits is a requirement to obtain a suitable plant breeding material. Present study was undertaken to evaluate fifty six F3 lines of the cross NIAW 1415 X Parula for grain yield, its attributing traits and leaf rust resistance. To estimate the genetic parameters like GCV, PCV, h­­2, GA and GAM, the F2 progenies were evaluated under normal as well as under artificial epiphytotic condition for all the nine quantitative characters.One of the ways in which the variability assessed is through the simplest approach of examining the variance component. The genetic variability studies in both the parents (NIAW 1415 and Parula) was found to be similar for most of the quantitative traits indicating, no much influence of rust pathogen on these traits. Whereas, the traits like SPS (Seeds Per Spike), TGW (1000 grain weight) and YP (Yield per plant) has recorded reduced level of expression with the respective values of 43.56, 35.45 (SPS), 30.25, 30.00 (TGW) and 25.45, 27.0 (YP) for respective parents indicating there is an influence of rust pathogen on yield contributing traits. Similar trend was recorded in F­3­ segregating population. High GCV (Genotypic Coefficient of Variation) and PCV( Phenotypic Coefficient of Variation) with the values of 21.20, 21.75 (GCV) and 28.57, 28.80 (PCV) were recorded for the traits such as PTP and YP respectively. This suggested the greater effectiveness of selection and improvement to be expected for these characters in future breeding programme. On the contrary, in protected experiment low GCV and PCV values were recorded for the traits such as, DFF (Days to Fifty percent Flowering), DM (Days to Maturity) and PH (Plant Height) indicating, less scope for selection as they are under the influence of environment. Interestingly some of the traits like PTP 9 productive tillers per Plant), SL (Spike Length), SKS (Spikelets per Spike) and YP (Yield per Plant) have recorded reduced level of GAM (Genetic Advance over Mean) in rust condition, hence the selection is not suitable for these traits in disease condition as they are effected by rust pathogen. Traits like PTP and YP recorded higher GAM hence, selection is desirable for these traits in protected condition.

The fuel properties of ethanol–ethyl acetate–biodiesel as 2000-10/0/90, 2000-15/5/76, 2000-20/10/70, 2000-25/11/64, 2000-30/11.5/58.5, 2000-35/12/53, 2000-40/12.5/47.5, 2000-45/13/42, 1900-10/22/68, 1900-15/26/59, 1900-20/29/51,1900-25/9/66, 1900-30/10/60, 1900-35/12/53, 1800-10/36/54, 1800-15/39/46, 1800-20/41/39, 1800-25/13/62, 1800-30/18/52, 1700-10/43/47, 1700-15/45/40, 1700-20/52/28, and 1700-25/27/48 have been determined in accordance with the Bureau of Indian Standards (BIS) and Institute of Petroleum (IP). When compared to bio-diesel, the substitute fuelprepared from 200°, 190°,180 and 170 proof ethanol were found to have relative density variations from 0.7923, 0.8113, 0.8265 and 0.8416and Kinematic viscosity of substitute was found to be 10 to 22% less than that of the biodiesel. The flash point of above substitute was found as 38.0, 25.4, 22.5, 19.6, 17.5 and 15.20 C respectively. The fire point of above substitute was found as 43.5, 30.8, 27.3, 24.9, 22.8 and 20.40 C respectively. The performance of a 3.73 kW diesel engine on alternative fuels of 200o ethanol with respect to brake power, fuel consumption and brake specific fuel consumption, O2 (%), Emission of CO2 (%), Emission of NO2 (ppm) and Emission of NO (ppm) revealed that these fuels have almost similar power producing capability with reduced exhaust emission. Thus, the stable alternative fuel of 200° proof ethanol had similar power producing capabilities, slightly higher fuel consumption, and lower exhaust emission as those of biodiesel fuel alone.

Abstract: For improving the yield potential of varieties and hybrids the decision should be made about the choice of right type of parents for hybridization. Based on the determination of divergence for the characters pertaining to green and ripe chilli all the 24 genotypes could meaningfully be grouped into 10 clusters. Cluster I was comprises maximum 7 and 5 genotypes for green and ripe chilli. Highest percent contribution characters to the divergence of the genotypes based on green chilli characters were fruit weight (22%), pedicel length (20.4%), pedicel: fruit ratio (13.5%), days to first flowering (12.19%), seeds fruit-1 (9.88%), fruit yield plant-1 (9.77%), fruit length (6.66) and fruit plant-1 (3.4%) and based on ripe chilli, characters were dry weight of ripe fruit (45.05%), fruit yield (26.09%), days to first flowering (8.3%), seeds fruit-1(7.1%), pedicel length (6.34%) and fruit weight (5.1%). The genotypes from the Cluster V, VII, VIII and XI could be selected for hybridization programme to produce highly heterotic genotypes as these were found to be most divergent with a number of desirable traits. Therefore, diversepromising genotypes viz., AC 575, AC 573 , Hyb 3(2)-2 , AC 587, AC 571, Hyb 3(2)-1 and AC 576 emerged as outstanding which may be used as such as breeding lines to develop the varieties after rendering to stability through necessary purification by selfing and single plant selection.

Abstract:A field experiments was conducted on sandy loam soil (Typic Ustipsemments) to study the effect of application of effluent water alone and in combination with farm yard manure, gypsum and sewage sludge on yield, content and uptake of wheat and succeeding fodder sorghum, physicochemical properties and nutrient availability of the soil. The experiment was laid out in a randomized complete block design (RCBD) with three replications comprised of ten treatments. Among the ten treatments, application of tube well water + FYM @ 5 t ha-1 (T6) showed the best positive effect and significantly increased grain (52.79 kg ha-1) and straw (62.77 kg ha-1) yield of wheat as well as succeeding fodder yield of sorghum (35.45 kg ha-1) which were 35.29, 41.57 and 33.72 per cent higher over effluent water applied alone, respectively. In general, all the macro (N, P, K, S) and micro-nutrients (Fe, Mn, Zn, Cu) contents and uptake by wheat and sorghum were higher in T6 treatment (Tube well water + FYM @ 5 t/ha) which was at par with T8 (Treated effluent water + FYM @ 5 t/ha), T7 (Treated effluent water + gypsum @ 1 t/ha) and T10 (Treated effluent water + sewage sludge @ 3 t/ha). It was also noted that application of treated effluent water increases EC and reduced fertility of soil, however, its detrimental effect was decreased when the effluent water or sludge applied with amendments i.e . FYM and gypsum. The application of T6 treatment (Tube well water + FYM @ 5 t/ha) increased the available N (265 kg ha-1), P (27.95 kg ha-1) and K (397 kg ha-1) status after harvest of wheat-sorghum sequence, while application of gypsum with irrigated by treated effluent water increases the available S(5.13 kg ha-1) status after harvest of sequence.

Abstract: Bovine leukocyte adhesion deficiency (BLAD) is a genetically transmitted disease and inherited as an autosomal recessive defect. Keeping this in view the present study was conducted to estimate incidence of carrier animals in a herd of breeding bulls for mutation in Integrin â2 gene, reared at Frozen Semen Bull Station (FSBS), Haringhata, Nadia, West Bengal, India. A total of 80 bulls of different age group were randomly selected from different cattle breeds (Sahiwal, Gir) to screen presence of BLAD syndrome in breeding sires. Genomic DNA was isolated from blood of the selected bulls. PCR parameters were standardized to obtain 570 bp amplicon. This amplified PCR product (amplicon) of ITGB2 gene was digested using TaqI (5’T“!CGA3’)restriction enzyme for screening of mutation in BLAD allele. TaqIPCR-RFLP revealed no such mutation thus indicating the absence of bovine leukocyte adhesion deficiency (BuLAD) allele in animals under study.

Abstract: An experiment was conducted to determine the genetic variability, nature of association among different yield attributes and their direct and indirect contribution towards yield of F2 and F3 populations of okra.In F2 and F3 populations of okra the analysis of variance, it was observed that, mean squares due to genotypes were significant for all the traits indicating the presence of genetic variability in the experimental material. The values of expression of the selected characters were found more in F3 population compared to F2 population. The GCV, heritability and genetic advance were higher for fruit weight (10.21, 54.00 and 3.22), number of branches (10.25, 62.00 and 1.12), fruit yield per plant (31.70, 54.00 and 6.05), number of fruits per plant (3.22, 51.00 and 0.83) and days to 50% flowering (1.94, 67.00 and 0.99) which might be attributed to additive gene action of inheritance in F3 population. From the correlation and path coefficient analysis revealed that, the top priority should be given to selection based on number of branches per plant (0.1742), number of fruits per plant (0.4763**), fruit length (0.3071**), fruit diameter (0.4135**) and fruit weight (0.9189**) for yield improvement and could be considered while formulating selection indices in the improvement of okra. Path coefficient analysis revealed that, fruit weight had maximum direct contribution (0.8732) towards fruit yield followed by number of fruits per plant (0.3787). This revealed that, F3 population showed more variability compared to F2 population in the segregating generations.

Abstract: One of the factors in limiting the crop growth is weeds and chemical control methods are considered to be appropriate in controlling weeds. But Continuous use of a particular herbicide may result in tolerance in weeds. To find out the suitable and most effective newly developed herbicides against important grassy species of weeds of wheat viz. Phalaris minor and other important weeds appearing in late sown wheatdue to development of resistance, which may be one of important limiting factors responsible for low yield that hampers crop productivity. Application of pinoxaden was found more effective against grassy weeds while carfentrazone was quite suitable against broad-leaved weeds (BLW). Most appropriate combination of herbicides against both (grassy and BLW) was pinoxaden 40 g and carfentrazone 25g which was almost at par to weed free situation.

Abstract: Pongamia pinnata is a medium-sized fast growing nitrogen fixing tree popularly known as Karanj. It is an excellent multipurpose tree with each and every part of the tree having specific use. The seeds of Pongamia contain 30 to 40 % thick reddish brown oil known as Pongam oil, which can be converted to biodiesel by transesterification method. Thirty candidate plus trees (CPTs) of P. pinnata were selected from 30 different locations in Uttar Pradesh for the study of genetic divergence in pod and seed characters. The eight Principal Component (PCs) explained large portion (97.12%) of the total variation. The study revealed that the cluster analysis performed on the scores of the first eight PCs resulted into five clusters with cluster IV comprised highest number of ten candidate plus tree followed by cluster II, III, V and I having 7, 7, 5 and 1 CPT, respectively. Seven CPTs in cluster II (S2, S3, S13, S22, S23, S26 and S27) had high mean values and combination of desirable traits and can be directly selected for further genetic improvement programme.

Abstract: A set of treatments involving four bio-regulators control, salicylic acid, thioglycolic acid and thiourea and and its effect on nutrient uptake, protein content and yield were studied on four varieties of pearl millet( RHB-121, RHB-173, RHB-177 and Raj-171) during the rainy seasons from 2014-15. Results revealed that the cultivar RHB-173 recorded significantly higher N, P and K uptake (66.08, 11.33 and 114.61 kg/ha) and yield (2175 kg/ha) over the other cultivars and higher protein content over Raj-171. Among the foliar spray, TU resulted in significantly higher N and P uptake (67.82 and 11.83 kg/ha) over other bio-regulators but remained at par with TGA in total K uptake andyield. Protein content in grain improved significantly by spray of bio-regulators over control.
