Nutrient uptake studies of mustard as influenced by seed rates and varieties in rice fallows

Abstract

Field experiment was conducted on clay soils during rabi, 2017-2018 of Agricultural College Farm, Bapatla to study the influence of seed rates and varieties on nutrients (N, P and K) uptake of rice fallow mustard. The treatments consisted of four seed rates and three varieties and replicated thrice with factorial randomized block design. As regards, results revealed that significantly highest plant height (113.0cm), drymatter accumulation (2059 kg ha-1), seed yield (650 kg ha-1) and N, P and K uptake were recorded in seed rate 12 kg ha-1at all the growth stages. Among varieties PM-28 significantly recorded highest plant height (110.1 cm), drymatter accumulation (1992 kg ha-1), seed yield (665 kg ha-1) and N, P and K uptake at all the growth stages. The interaction between seed rates and varieties was found not significant for drymatter, seed yield, straw yield and NPK uptake of rice fallow mustard.
