Growth and Yield of Mustard (Brassica juncea L.), Dry Weight of Weeds and Weed Control Efficiency Influence by Different Planting Methods and Weed Management

Abstract

A field experiment was conducted during rabi season of 2014-15 at College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari with fifteen treatment combinations. Treatments were replicated thrice as per randomized block design with factorial concept. Significantly higher values of plant height (171.63 cm), number of branches plant-1 (18.07), dry matter accumulation (80.07 g plant-1), number of siliqua plant-1 (204.16), seed yield (1851 kg ha-1) and stover yield (3808 kg ha-1) were recorded with row spacing of 45 cm x 10 cm with normal planting (P2) followed by 30/60 cm x 10 cm with paired row planting (P3). Likewise, significantly maximum plant height (184.10 cm), number of branches plant-1 (19.36), dry matter accumulation (84.42 g plant-1), number of siliqua plant-1 (223.31), seed yield (2085 kg ha-1) and stover yield (4230 kg ha-1) were obtained with W4 (Pendimethalin @ 1.0 kg ha-1 as PE + Quizalofop - P - ethyl @ 0.04 kg ha-1 at 20 DAS + HW and IC at 40 DAS). Significantly lowest dry weight (269.59 kg ha-1) of total weeds was noted under treatment P1 (30 cm x 10 cm with normal planting). In weed management treatments W4 recorded markedly lower value of dry weight (168.31 kg ha-1) of total weeds. Hence the crop sown with wider row spacing and weed management with integration of all methods showed favourable growth leads to higher yield of mustard.
