A Study on the Performance of Different Rapeseed-Mustard Varieties under Late Sown Condition of Jaintia Hills of Meghalaya

Abstract

A field experiment entitled “A study on the performance of different rapeseed-mustard varieties under late sown condition of Jaintia Hills of Meghalaya” was conducted in The District and Local Research Station, Jowai, Meghalaya, during rabi season of 2020-2021. The experiment consisted of eight rapeseed-mustard varieties namely PM-26, PM-27, NRCHB-101, SURBHI, BULLET, ANMOL, LOCAL (Meghalaya), LOCAL (Assam) which were laid out in Randomized Block Design (RBD) with three replications, to study the growth and yield performance of different rapeseed-mustard varieties and as well to find out the best suitable variety under late sown condition of Jaintia Hill of Meghalaya. The results revealed that there was a significant difference among all the rapeseed-mustard varieties for all the growth and yield attributes studied. Among the eight rapeseed-mustard varieties, it is found out that the variety NRCHB-101 perform the best and very suitable to the condition, followed by the variety SURBHI, BULLET and ANMOL. The variety (NRCHB-101) showed significantly higher plant height (151.77 cm), number of branches^-1 (13.25), number of siliqua plant^-1 (159), seeds siliqua^-1 (13.25), seed yield (1631.04 kg ha^-1),  stover yield (4261.84 kg ha^-1) and oil yield with 442.56 (kg ha^-1). Further, mean result of the study revealed that highest gross returns (Rs 75841.51) , net returns (Rs 52561.51) and B:C rartio (3.25) was recorded in the variety NRCHB-101. Therefore, NRCHB-101 can be recommended for cultivation under late sown condition of Jaintia Hils of Meghalaya
