A field experiment was conducted during rabi, 2017-2018 on clay soils of Agricultural College Farm, Bapatla to find out the effect of seed rates and varieties on yield of rice fallow mustard and to calculate economics. The treatments consisted of four seed rates (S1:6 kg ha-1 , S2:8 kg ha-1 , S3:10 kg ha-1 and S4:12 kgha-1 ) and three varieties (V1: NPJ-112, V2: PM-28, V3: Pusa bold) and laid out in factorial randomized block design and replicated thrice. Experimental results revealed that significantly highest seed yield (650 kg ha-1 ) and stalk yield (1450 kg ha-1 ) was recorded in seed rate 12 kg ha-1 . Among varieties PM-28 significantly recorded highest seed yield (665 kg ha-1 ) and stalk yield (1652 kg ha-1 ). Significantly highest harvest index () was recorded with the variety NPJ-112 and harvest index was non-significant for seed rates. The interaction between seed rates and varieties was found not significant for seed yield, straw yield and harvest index of mustard. The highest gross return (Rs 29, 268 ha-1 ), net return (Rs 17, 308 ha-1 ) and return per rupee invested (Rs ) was recorded with the 12 kg seed ha-1 . The variety PM-28 recorded highest gross return (Rs 29, 961 ha-1 ), net return (Rs 18, 241 ha-1 ) and return per rupee invested (Rs ). | Effect of seed rates and varieties on yield of rice fallow mustard and their economics
