Effect of energy requirement on growth and development of mustard [Brassica juncea (L.)] cultivars at different phenological stages

A field experiment was conducted during Rabi season of 2014 on the topic entitled “Effect of energy requirement on growth and development of mustard [Brassica juncea (L.)] cultivars at different Phenological stages” in sandy loam soil of N.D. University of Agriculture and Technology, Kumarganj, Faizabad (U.P.). The experimental comprised of three planting geometry viz., 40×15cm, 40×20cm, 40×25cm and three varieties viz., Varuna, Vardan and NDR-8501. Highest Thermal use efficiency was recorded when sowing was done on 40×15cm planting geometry, followed by sowing done on 40×20cm. NDR-8501 variety was found more conducive for growth development, grain yield and thermal use efficiency. Thermal unit (1659.40days), Photo thermal index (129.64), from sowing to maturity produced the high yield of Indian mustard.
