Abstract:
This paper aims to determine the yield effect of lentil under rice-based cropping pattern by taking 3 varied transplanting dates viz. D₁: 10^th July, D₂: 25^th July and D₃: 10^th August in major plots and 4 varieties viz. Tulaipanji, Khasa, Gobindobhog and Kalonunia in subplot in a design Split Plot Design at a farm of Uttar Banga Krishi Viswavidyalaya located at Pundibari, Cooch Behar, West Bengal (2016-2017 and 2017-2018). The two years average data showed that the crop transplanted on 10^th July improved growth attributes (plant height, DMA, LAI, SPAD value), yield parameters (numbers of panicle m^-2, numbers of grain panicle^-1, 1000 grain weight), Yield (Grain and straw) of aromatic rice irrespective of the varieties. However, minimum data was revealed from a rice crop transplanting on 10^th August. Regarding variety, ‘Khasa’ performed better in respect numbers of panicle m^-2, numbers of grain panicle^-1, Test weight (1000 grain weight), grain and straw yield. Growth parameters and grain yield of residual effect of succeeding lentil crop was observed maximum in plots transplanted at 10^th July. However, Kalonunia variety transplanted plot recorded maximum yield of grain (1.135 t/ha) which was equivalent to the plot of Khasa variety (1.131 t/ha).
