Abstract: 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.
