Input management for sustaining mustard (Brassica juncea) production under late-sown semi-arid situations of Rajasthan

TL;DRAbstract

A field experiment was conducted during 1993-94 to 1995-96 to study the effect of different agronomic inputs for taking good sustainable yield of mustard [Brassica juncea (L.) Czernj. & Cosson] under late-sown conditions. Maximum e seed yield of mustard was recorded in all the years where all the four major agro- inputs, viz. thinning, fertilizer, irrigation and plant protection, were used as per recommendations. Considering the single factor, irrigation proved to be the most critical input in this semi-arid region, when there was no winter rains and rainfall during the season was low or normal. The reduction in the yield under no irrigation was up to 39% followed by fertilizer which contributed up to 28 % yield. During the year when rainfall was more than normal, that too up to October and was accompanied with winter rain, fertilizer contributed to the yield up to 38% and proyed the most critical. In its absence reduction In the mustard yield was up to 38 %. This was followed by p
