Growth and yield of hybrid mustard (Brassica juncea L.) as influenced by foliar nutrition in Gangetic plains of West Bengal
Abstract: A field experiment was conducted to study the effect of foliar nutrition on hybrid mustard var. Kesari-5111 during rabi seasons of 2018-19 and 2019-20 at Instructional Farm, BCKV, Jaguli, Nadia (West Bengal). Results revealed that mustard plot fertilized with recommended dose of chemical fertilizer (RDF) along with the foliar application of di-ammonium phosphate (DAP)at2%recorded the highest plant height, leaf area index, dry matter accumulation and number of siliqua plant-1, number of seeds siliqua-1.. Different foliar nutrition significantly improved the seed yield of hybrid mustard by 15.8 to 81.3% over control plot. The maximum seed yield of hybrid mustard was recorded as1971 kg ha-1 with DAP @ 2% followed by sulphur @ 0.5% obtaining seed yield of 1867 kg ha-1. Among the foliar spray treatments, highest oil content (39.9%)was recorded with sulphur at 0.5%followed by Boron (Borax) at 0.1%, recording 38.7% oil content. Based on the experimental results,it may be recommended that an integration of recommended dose of chemical fertilizer (RDF) along with either foliar application of DAP at 2% or Urea at 2% or Sulphur at 0.5% enhanced the growth and yield of hybrid mustard as well as improved the soil nutrient status in Gangetic alluvial soil of West Bengal.
