Abstract: A field experiment was conducted during kharif 2011 at Regional Horticultural Research and Extension Centre, University of Horticultural Sciences, Bagalkot, Karnataka to study the effect of sequential application of herbicides on weed management in drill sown onion under rainfed condition. Seventeen weed control treatments were tested in randomised block design replicated thrice. All the herbicide treatments significantly reduced dry weight of weeds over unweeded check. Weed free check recorded significantly lower dry weight of weeds. Among the herbicide treatments, sequential application of oxyfluorfen 0.08 kg ha-1 followed by (fb) oxyfluorfen 0.25 kg ha-1 was quite efficient in controlling weeds which reflected through decreased weed dry weight and increased weed control index. This herbicide treatment also recorded significantly higher bulb yield (30.16 t ha-1), growth and yield parameters. The weed index was also lowest in the above treatment (13.50%) as compared to unweeded check (91.89%) and other treatments (25.22 to 90.04%).

Abstract: To develop the usefulness of plants as bio indicators requires an appropriate selection of plant species which entail a highly important for a particular situation. The present study was undertaken to evaluate air pollution tolerance index (APTI) of five different plant species around City area and Navsari Agricultural University campus (Control). Among the trees in the selected area Cassia fistula depicted highest APTI value as compared to other species followed by Saraca asoca and Sizygium cumini and proved to be tolerant variety in the city area as per the APTI value. However, Tectona grandis and Terminalia catapa found to be intermediate sensitivity for the polluted site (City area). Hence, it is recommended to plant S. asoca, S. cumini and C. fistula trees in city / industrial area to cope the environmental problem. The study also suggests that performance index might be very useful in the selection of appropriate species which can be expected to perform well for the development of green environments.

Abstract: Organic farming is a holistic production system of farm management to create an eco-system to achieve sustainable productivity. Due to the external effects of chemicals, farmers recently practiced non-conventional bio pesticides and fungicides in crop protection and management. In this context, the present study had been taken up to study the determinant factors of adoption of bio pesticide and fungicides in Erode district of Tamil Nadu. Logit analysis revealed that education, land holding size and extension agency contact are the most significant factors influencing adoption of bio pesticide and fungicide usage in Erode district. Partial budgeting estimates shows that using of bio pesticides-fungicides in rice; turmeric and sugarcane cultivation is economically viable. From garret rank analysis it could be concluded higher price is the major constraint in adoption of bio pesticides indicated by farmers.

Abstract: Fifty plant species belonging to different families were evaluated for their mycotoxic effect against Fusarium oxysporum f.sp. lini causing wilt disease in linseed in in vitro. All the test plants showed different levels of toxicity and inhibit the mycelial growth of fungus (8.44-82.33%) significantly. Maximum inhibition was recorded with leaf extract of Xanthium strumarium (82.33%) followed by Tribulus terrestris (78.68%) and Nerium odorum (75.00%) respectively. Leaf extract of Xanthium strumarium and Tribulus terrestris were again tested in wilt-sick plot for their effectiveness in comparison to bio-agent Trichoderma harzianum and mycorrhiza alongwith fungicide carbendazim. Total 11 treatments were tested and all were found significantly effective in managing the disease. Amongst them, maximum mean disease control (54.39%) with maximum seed yield (513.73 kg/ha) was recorded with treatment: seed and soil treatments with extract of Tribulus terrestris (10% W/V) followed by treatment, seed and soil treatment with T. harzianum (2.5 kg/ha) and treatment, seed and soil treatment with mycorhiza (12.5 kg/ha), respectively during both the years. Out of 200 genotypes screened against the disease under sick-field condition only five genotypes namely ‘LCK-6028’, ‘PKDL-71’, ‘Type-397’, ‘SLS-58’ and ‘NDL-2004-5’ were found resistant continuously both the years and may be utilized in future resistance breeding programmes.

Abstract: Environmental changes in temperature, light and water leads to altered the plant gene expression. Exposure of plants to several degrees of elevated temperatures induces the expression of evolutionary conserved genes coding for the synthesis of heat shock proteins (HSPs). The study of genetic variability, heritability and genetic advance showed the highly adverse effect of heat stress. The range of temperature between 30p C to 60p C revealed the growth retardation in plant growth, although the temperature upto 30p C showed the normal morphology as its primary observation. The heat shock protein of molecular weight less than 20kd and more than 70kd were the evident of alteration in their gene expression. This observation showed that genetic alteration in heat shock protein due to thermal stress.

Abstract: A field experiment was conducted at University of Agricultural Sciences, Dharwad (Northern Transition Zone of Karnataka) during kharif 2012 and 2013 to study the influence of fungicide (Opera 18.3% SE) to withstand moisture stress effects on growth, physiology and productivity in soybean. The experiment comprised of 8 treatment combinations with two factors viz., fungicide as factor – I (with and without fungicide spray) and moisture stress as factor – II (withholding water for 0, 5, 10 and 15 days) imposed on 40 DAS. Increase in duration of stress from 0 to 15 days reduce the morphological and growth traits viz., plant height, number of branches, total dry weight, LAI and SLW where, these were significantly lower in moisture stress for 15 days compared to normal watered control. The chlorophyll content, rate of photosynthesis and stomatal conductance were significantly higher in control over stress for 15 days. Moisture stress for 10 (3844 kg/ha) and 15 (3666 kg/ha) days significantly reduce the yield compared to control (4272 kg/ha). Application of opera reduced the stress effects and improved these parameters in all the stress treatments over their respective counterparts without fungicide treatment.

Abstract: In the present study, it has been observed that hog cholera was endemic in North Eastern Region of India including Assam. Free grazing pigs were mostly affected with acute course of the disease. The present study was also carried out to evaluate the efficacy of different immunological tests (Fluorescent antibody test (FAT), Sandwich Enzyme Linked Immunosorbent Assay (S-ELISA) and Agar gel precipitation test (AGPT) for diagnosis of hog cholera in clinical and postmortem samples. 314 suspected samples were collected from 120 clinically affected pigs. All samples were collected from 9 outbreaks occurred in different parts of North-Eastern region of India and processed for detection of hog cholera virus (HCV) antigen. In this study, 163 (51.91%) samples showed positive result in direct FAT test, 147 (46.81%) samples were found positive in Sandwich ELISA test for HCV antigen and 19.74 per cent samples were found positive in AGPT test for HCV antigen. Isolation of hog cholera virus was attempted from field samples in pig kidney-15 (PK-15) cell line.For isolation of HCV, 26 samples such as leucocytes tonsil, Mesenteric lymph node (MLN), spleen, pancreases and kidney were passaged in PK-15 cell line. Only 14 isolates could be detected by direct FAT and S-ELISA. Due to non cytopathic nature of virus, few blind passages were required. Direct FAT could detect the viral antigen even in first passage level itself while S-ELISA requires two-three passages. Hence Direct FAT and S-ELISA were found comparable to each other for detection of hog cholera virus in clinical, postmortem and cell cultured propagated samples. Statistical analysis also revealed that FAT and Sandwich ELISA were competitive to each other for HCV antigen detection and significantly (P < 0.05) different from that of AGPT.In all the above three tests, it was also found that tonsilar tissue/isolates exhibited highest number of positive cases.

Abstract: This study aimed at investigating the ecological need, morphometry and meristics, age and growth, food and feeding of recently invaded alien Oreochromis niloticus in the Yamuna and the Ganga River. Observed meristic characters of the fish were similar and fixed in both the rivers while there was a slight variation in age and growth. In general, growth rate of 2nd year age group of fish was a little higher in the Yamuna. The gut content analysis showed that O.niloticus predominantly feed on phytoplanktons and poorly on zooplankton which indicate its omnivorous nature. The calculated trophic level of O. niloticus was 2.10 in the Ganga and 2.08 in the Yamuna River. There was a positive correlation between length and weight of fishes in both the rivers, yet it was slightly higher in the Yamuna River indicating better growth of O. niloticus in the Yamuna River.Gut content analysis revealed dietary overlap with indigenous Indian major carp, Labeo rohita. The results of this study suggested that invasion route of O. niloticus in the Ganga River was through the Yamuna river as there was no morphometric and meristic variations in the fish at first matuarity stage, showing any adaptive phenotypic plasticity.

Abstract: Study was conducted to evaluate the effect of keeping nutritional and functional attributes of papaya pulp potential of whey to be used in nutritious and health promoting beverage along with its shelf life, the study by evaluating sensory and chemical quality of papaya pulp based whey beverage. There were paneer whey used as raw material, three level of sugar (8%, 10% and 12%) and three level of papaya pulp (10%, 20% and 30%) used for preparation of Papaya Pulp Based Whey Beverage. This product stored at 50 C as refrigerated temperature for four storage periods (0 day, 5 days, 10 days and 15 days). This process replicated three times. The findings of study imply that the different levels of sugar and storage periods affect the sensory attributes (flavour, colour & appearance sweetness, and overall acceptability) and chemical content (moisture, fat, lactose, sucrose and total solids) but papaya pulp does not affect total solids content of beverage. The interaction of sugar and papaya pulp affect significantly all the attributes of sensory and chemical qualities except sweetness. Whereas interaction of sugar with storage periods and papaya pulp with storage periods affect non-significantly all sensory attributes and some chemical content except overall acceptability. The overall interaction of sugar, papaya pulp and storage periods non-significantly affected of all sensory attributes (flavour, colour & appearance and sweetness) and all chemical attributes (fat, protein, lactose, sucrose, ash and total solids) except overall acceptability.

Abstract: Field experiment was conducted to study the effect of bacterial Biofertilizers on Oryza sativa L. plant. Bacterial biofertilizers like Phosphobacteria and Azotobacter sp. were isolated from the partial flood affected soil of agricultural crops by employing plating techniques. The microbial inoculants coated seed were sowed first in nursery, containing sterile soil samples. Controls were also maintained without a bacterial biofertilizers. The plant height and collar diameter of the seedlings were measured after 30, 60, 90 and 120 days of sowing, the plant growth parameters like morphological and Bio-chemical parameters were analyzed. The morphological parameters like plant height, number of tillers, root length, ear length were increased in combined inoculation of Phosphobacteria and Azotobacter sp. with 100% RDF (recommended dose of fertilizers) than combined inoculation with 75% RDF inoculations and control plants respectively. Physico Chemical parameters like Chlorophyll content, Protein, Carbohydrate, content were also increased in combined treatment of Phosphobacteria and Azotobacter with 100% RDF. The present study demonstrated the positive effects of co-inoculation of NFB and PSB along with RDF. This finding could be useful for developing a new formulation for biofertilizers under field conditions.

Abstract: Growth and reproductive status of improved and unimproved stands were studied. Significant variation in tree height, GBH, volume and crown diameter was recorded among studied stands. Trees located in SPA showed maximum tree height, girth, volume as well as crown width as compared to CSO and conventional plantation. Trees located in the SPA recorded the lowest non-fruiting individuals (15.5%), followed by CSO (29.2%); however, per cent non-fruiting individual was more in conventional plantation (43.0%). Considering fruit yielding category, trees of SPA recorded high fruiting class, whereas as trees of CSO recorded low fruiting class. The overall observation shows that fruit yield in SPA is found to be more, followed by conventional plantation as compared to CSO. It shows the need of silvicultural practices for seed yield improvement in the improve stands.

Abstract: The global climate change, due to GHGs is making the nutritional security and fruit production sustainability more difficult day by day; reasons may be increase in temperature and variability in precipitation pattern results in abiotic stresses like heat, drought and flooding. Horticulture, the major component of agriculture in India, is no exemption from the threat of climate change impacts. In this era, Organic farming is best adaptable option for mitigating climate change due to superior ability to reduce emissions of GHGs as well as increase soil carbon sequestration an appropriate combination of organic source of nutrients, cover crops, less intensive tillage etc. An organic production system is designed to a) enhance biological diversity within the whole system; b) increase soil biological activity; c) maintain long-term soil fertility; d) recycle wastes of plant and animal origin in order to return nutrients to the land, thus minimizing the use of nonrenewable resources; e) rely on renewable resources in locally organized agricultural systems; f) promote the healthy use of soil, water, and air, as well as minimize all forms of pollution. Many findings revealed that organic strategies are diversification of crop and an increase of soil organic matter, which both could enhance resilience against extreme weather events. Organic farming system reduces N2O emissions due to lower nitrogen input and less CO2 emissions through erosion due to better soil structure and more plant cover than conventional system. In case of organic farming, biomass is not burned. It reduces the CH4 and N2O emissions in comparison to conventional agriculture, where crop residues are often burnt on the field. Organic farming avoids these emissions, as no chemical nitrogen fertilizers are used. In organic farming, nitrogen input stems from application of manures and compost, or is fixed from the air by leguminous plants. Thus, organic farming could be a vastly adaptable to climate smart horticulture, and affords mitigation for climate change. It also provides a high degree of diversity in the eco-system. Although remarkable, organic farming several critical issues remain to be resolved. To begin with there is a need for more research. Looking to the needs and importance of the organic farming, Navsari Agricultural University (NAU) has already started cultivate horticultural crops from 2005 and have remarkably progressed in this sector.

Abstract: Field experiment was carried out in farmers field during 2006 and 2007 at Marakadadoddi village, Maddur taluk, Mandya (Karnataka) to study the influence of cultivars and INM practices on yield potentiality aerobic rice. Results revealed that significantly higher grain yield was recorded with KRH-2 hybrid rice (60.2 q ha-1) followed by BR-2655 (55.5 q ha-1) and the lowest grain yield was obtained with IR-30864 (50.8 q ha-1). Significantly higher grain yield with KRH-2 hybrid rice may be due to its superiority in yield attributes such as number of tillers (39.32), number of productive tillers (35.38) and test weight (24.79 g) over other cultivars. Higher nutrient uptake was observed in KRH-2 (142.76 kg nitrogen ha-1, 59.08 kg P ha-1 and 136.99 kg K ha-1) compared to other cultivars like BR-2655 and IR-30864. The application of 50 per cent N through inorganic fertilizer + 50 per cent N through vermicompost (N4) was recorded significantly higher number of tillers (43.41 hill-1), productive tillers (40.24 hill-1), test weight (25.87 g), absolute growth rate (g day-1 at 60-90 DAS) and grain yield (63.1q ha-1) as compared to other integrated nutrient practices. Integrated nutrient management with 50 per cent N through inorganic fertilizer + 50 per cent N through vermicompost (N4) resulted in higher N (151.21 kg ha-1), P (62.58 kg ha-1) and K (146.98 kg ha-1) uptake as compared to other combinations of N5, N3, N2 and N1.Among the different cultivars KRH-2 recorded higher net return (Rs. 21,289 ha-1 and 1:2.33) over the BR-2655 (Rs. 18,690 ha-1 and 1:2.20) and IR-30864 (Rs. 15,718 ha-1 and 1:2.00. Maximum net return of Rs. 20,401 ha-1 and B:C ratio (1:2.57) were found in 100 per cent RDF + Biofertlizer (N2), whereas, lowest net return of Rs. 16,512 ha-1 and B:C ratio (1.81) were recorded in 50 per cent recommended dose of nitrogen + 50 per cent N as enriched compost (N5).

Abstract: An experiment was conducted during the rabi season 2012-13 on clayey soil at Junagadh Agricultural University, Junagadh to study the sources and levels of sulphur fertilization on productivity and economics of wheat (Triticum aestivum L.). Result revealed that plant growth parameters viz., plant height at 60 DAS, dry matter accumulation at 60 DAS, number of total tillers at 60 DAS and harvest as well as yield attributes viz., length of spike, was significantly improved when sulphur applied through gypsum. Significantly higher grain (4785 kg ha-1) and straw (6866 kg ha-1) yields of wheat were recorded when sulphur applied through gypsum, however it remained at par with bentonite. This source was also recorded higher net profit of Rs. 55616 ha-1 and B:C ratio of 2.59. Application of 30 kg S ha-1 recorded significantly higher growth parameters viz., plant height at 60 DAS and harvest, dry matter accumulation at 30, 60 DAS and at harvest, number of total tillers at harvest and effective tillers. Among yield attributes length of spike and number of spikelets per spike, were recorded with application of 30 kg S ha-1 and remained at par 45 kg S ha-1. Significantly higher wheat grain (5188 kg ha-1) and straw (7060 kg ha-1) yield were obtained with 30 kg S ha-1. Application of sulphur at 30 kg ha-1 registered significantly maximum net profit (Rs. 58557 ha-1) which was 72.3 and 48.6 per cent higher over levels of 15 and 45 kg S ha-1, respectively with B:C ratio of 2.52.

Abstract: : A field experiment was conducted during kharif 2013 on loamy sand soil at Agronomy Farm, College of Agriculture, S.K.R.A.U., Bikaner to study the effect of moisture conservation practices on pearl millet. Result revealed that modification in surface configuration as ridge and furrow, plastic mulch and pre sowing seed hardening with KNO3 significantly increased dry matter accumulation and total number of tillers/plant, ear head length, test weight, grain yield, stover yield and biological yield also significantly increased with the modification in surface configuration as ridge and furrow method over flat sowing, straw and dust mulch and without seed hardening. Modification in surface configuration as ridge and furrow, plastic mulch and pre sowing seed hardening with KNO3 enhanced grain yield to the tune of 22.21, 14.40 and 48.82 and 10.50 per cent over flat sowing, straw and dust mulch and without seed hardening. Ridge and furrow practice of sowing a way of modification in surface configuration proved more effective and gave significantly higher water use, water use efficiency, net return 23985, 28189 and 22765 Rs./ha and B: C ratio 2.92, 3.29 and 2.64, respectively.

Abstract: : The effect of different doses of two heavy metals such as cadmium and lead on Bean (Dolichos lablab L.) plants was studied. Significant reduction in Chlorophyll and Total sugar was observed at increasing doses of both Cd and Pb. Variable results were obtained in protein concentration and peroxidase activity at various doses of Cd and Pb. Catalase activity was reduced at lowest dose but stimulated at higher doses of both Cadmium and Lead.
