Abstract:

In India, oilseed Brassica are grown over an area of about 6.3 million hectares with an annual production of 7.92 million tones with  an average yield of 1304 kg/ha whereas in Rajasthan  it was still 1422kg/ha. The severe attack of many diseases not only deteriorates the quality of the seed, but also reduces the oil content considerably. Among the diseases, white rust caused by   Albugo candida (Pers. Ex Hook) O. Kuntze, is an important disease of a wide variety of Brassica crops. Its infection causes disfiguring white pustules on leaves, flowers stems and pod leading to yield losses. Mustard is an economic important crop in Alwar district of Rajasthan more than 2.5 lac ha area is under mustard cultivation. Management technology recommended for white rust disease has not much effective.  Hence, looking for the improve disease management technology. So, there is need of   assessment and refinement in technology through on-farm testing.  The technology was evaluated through OFT during 2014-15 and 2015-16 cropping season in different villages of Bansur tehsil of Alwar district. In this area farmers used micro sprinkler irrigation along with high dense plant population and also provide frequent irrigations.  The assessment and refinement of technology showed that the seed treatment with metalaxyl 35 SD and two foliar spray of metalaxyl 8% + mancozeb 64% (1st at 35-40 DAS and 2nd spray 65-70 DAS) along with timely sowing and  3-4 irrigation through sprinkle during the crop season recorded minimum disease intensity (8.2%) and maximum yield 1875 Kg/ha as compare to farmers practices (disease intensity 12.05% and yield 1215 Kg/ha). The average economic gross return and cost benefit ratio is also higher in refined technology (T3) was Rs 65180 /ha and 1:2.56 followed by treatment (T2) Rs 48235 and 1:1.83 as compared with farmers practices Rs 36930 and 1: 1.73.
