Cultural management practices in relay (paira /utera) grass pea (Lathyrus sativa L.) on rice-fallows may intensify pulse production in the Eastern Ingo-Gangetic plains, but choice to be made, requires assessment of appropriate rice stubble and micro nutrient management. A field experiment was conducted at the Central Research Farm of the Bidhan Chandra Krishi Viswavidyalaya, the State Agricultural University, Gayeshpur, India (22058/N latitude; 88031/E longitude; 9.75 amsl, Inceptisol, tropical sub-humid region)during winter seasons of2015-16, 2016-17 and 2017-18 to evaluate opportunity of improving yield of relay grass pea (variety Biol 212) with conservation agriculture practices. The experiment was laid out in a split-split design with three replications having two levels of sowing method (relay crop sown 10 days before rice harvesting and sowing with multi crop zero cum fertiliser drill on the day of rice harvest), four levels of rice residue (rice cut at ground level, residue kept at the height of 6 inch, 9 and 12 inch) and four levels of micronutrient spray (control, boron 0.2% at pre flowering stage, molybdenum 0.05% at pre flowering stage and boron +molybdenum at pre flowering stage). Zero tillage produced more nodules, more seed and bio yield as compared to relay cropping. Retention of rice residue at 12 inch above soil surface recorded highest seed yield (1074 kg/ha) as well as bio yield (4120 kg/ha). Boron along with Molybdenum had produced highest number of pods / plant, seed yield (1099 kg/ha) and bio yield (4149 kg/ha). Application of boron and molybdenum at pre flowering stage and relay sowing of lathyrus and 12 inch anchored residue may increase overall pulse production on rice -fallow areas of eastern IGP.
