Variability of Stemphylium vesicarium on Onion (Allium cepa L.) Open
The onion (Allium cepa L.) crop is affected by a number of diseases in the field as well as in storage which cause a significant reduction in yield leading to heavy losses each year depending on weather conditions. Leaf blight and leaf spo…
Impact of Organic, Inorganic and Biofertilizers on Crop Yield and N, P and K Uptake under Rainfed Maize-Wheat Cropping System Open
Integrated effect of organic, inorganic and biofertilizers on crop yield and N,P and K uptake under rainfed maize-wheat cropping system and available nutrients during 2015-2016 is being studied in sandy loam at Jammu under the INM maize-wh…
Effect of Organic, Inorganic and Bio fertilizers on Soil Physicochemical Properties in Rainfed Maize-wheat Cropping System of Jammu Open
An experiment was conducted during 2015-2016 in sandy loams at Jammu under the INM in maize-wheat system. The results revealed that the application of recommended levels of NPK to maize-wheat with FYM, VC and biofertilizers (Azotobacter an…
Screening of Brinjal Germplasm against Wilt Complex Disease Open
Thirty germplasm of Brinjal (Solanum melongena L.) were screened against wilt complex pathogens viz., Fusarium oxysporum f.sp. melongenae, Rhizoctonia solani and Sclerotium rolfsii under field and pot experiments. Germplasm (30) that were …
Pathogens Associated with Foliar Blight of Onion Open
Onion is an important crop grown worldwide for its culinary and medicinal properties. One of the major bottlenecks in its production is the foliar blight disease. The disease is responsible for causing huge losses in its successful product…
Weather Based Forewarning Model for Yellow Rust of Wheat in Scarcity Zone of Jammu & Kashmir Open
A forewarning model of stripe rust of wheat for predicting the disease initiation in Jammu sub-tropics was developed by the analysis of disease severity data pertaining to the years from 2005-06 to 2012-13 obtained from AICRP research expe…
Management of Brown Spot of Rice (Oryza sativa L.) Caused by Bipolaris oryzae by Bio-Control Agents Open
Under laboratory conditions using dual culture techniques, bio-control agents (Trichoderma viride, T. harzianum, Pseudomonas fluorescens and Bacillus subtilis) were tested against Bipolaris oryzae the causal organism of brown spot of rice.…
Effect of soil solarization on the growth of onion (Aliium cepa L.) and onion blight disease Open
Soil solarization, with the addition of soil amendments, was carried out for a period of six weeks. The maximum temperature of solarized plots was 9.2–11.3oC higher than that of non-solarized plots and the minimum temperatures in solariz…

Prevalence of Spot Blotch (Bipolaris sorokiniana) of Wheat and its Management through Host Resistance Open
Survey was conducted at dough stage to assess the spot blotch disease of wheat in different locations of Jammu sub-tropics during 2015 cropping seasons. The disease was reported in all the wheat growing areas of Jammu subtropics with the m…
Germplasm Evaluation and Characterization of Slow Rusting Resistant Gene against Stripe Rust of Wheat Open
Thirty one wheat germplasm lines were screened under natural epiphytotic conditions against stripe rust at University Research Farm, Chatha, during Rabi, 2014-15. On the basis of final rust severity (FRS), area under rust progress curve (A…
Screening of Rhizo-Bacterial Isolates for Bio-control Potential against Soil-Borne Diseases in Brinjal Open
Studies were carried out from 2013 to 2015 with the objectives to isolate and identify some indigenous rhizobacterial strains against major soil-borne pathogens of brinjal. Seventy thizobacterial isolates were characterized based on colony…
Assessment of Wheat Varieties for Slow Rusting and Management of Stripe Rust Caused by <i>Puccinia striiformis</i> Open
Fifty wheat varieties were screened under artificial epiphytotic conditions against stripe rust of wheat during Rabi, 2013-14. On the basis of final rust severity (FRS), AURPC (Area Under Rust Progress Curve), r (Infection Rate) and CI (Co…
