Growth and yield response of transplanted mustard (Brassica juncea L.) under different planting schedule in north Gujarat agroclimatic region

Abstract

A field experiment was conducted on transplanted Indian mustard during rabi season of 2020-21 at Sardarkrushinagar,
Gujrat in loamy sand soil. The experiment consisted twelve treatment combinations, with four planting geometry viz., 45
cm × 30 cm, 45 cm × 45 cm, 60 cm × 30 cm and 60 cm × 45 cm accommodate in main plots and three dates of transplanting
viz., 31st October, 10th November and 20th November taken in subplots were undertaken in split-plot design with three
replications. Significantly higher plant height at 30 & 60 DAT (94 & 180 cm), leaf area index at 30 & 60 DAT (0.87 & 2.03)
and oil yield (893 kg/ha) were recorded with mustard transplanted at 45 cm × 30 cm and, whereas, higher number of
secondary branches per plant (26.3) and number of siliquae per plant (718) were recorded at 60 cm × 45 cm. Mustard
transplanted at 45 cm × 30 cm spacing recorded significantly higher seed yield (2187 kg/ha) which was remained
statistically at par with spacing 45 cm × 45 cm (2070 kg/ha). Crop transplanted on 10th November significantly out yielded
(2143 kg/ha) over the 20th November (1829 kg/ha) but remained statistically at par with 31st October (1996 kg/ha) in terms
of seed yield.
