Response of different rapeseed (Brassica campestris) and mustard (Brassica juncea) varieties on growth and yield under zero tillage conditions

A field experiment was conducted at Langthabal Makha Leikai, Imphal West, Manipur, India during the rabi season of 2018-2019 to study the response of different rapeseed and mustard varieties on growth and yield under zero tillage conditions. The results indicated that the adoption of zero tillage had significant response on growth, yield and yield attributes on different rapeseed and mustard varieties. The variety NRCHB-101 gave the maximum seed yield (930.20 kg/ha) and stover yield (1804.45 kg/ha) while for harvest index, the variety TS-38 was found highest (34.41%). The variety NRCHB-101 recorded the maximum net return (₹23,237/ha) and benefit cost ratio (1.99) among the rapeseed and mustard varieties. From this research output, it can be concluded the variety NRCHB-101 may be used on commercial scale by the farmers in terms of productivity and profitability making mustard cultivation viable.
