Abstract
A field experiment was conducted at research farm of IARI, New Delhi with an aim to study the effect of weather variability on crop growth and seed yield. Three cultivars of Brassica were sown on three dates at an intervals of 15 days during 2007–2008 rabi season. The leaf area index, biomass, chlorophyll concentration index and aphid infestation were measured at different stages of crop growth. Study revealed that all the growth parameters were affected due to the change in the weather conditions. First sown crop experiences 2–3°C lower temperature as compared to late sown crop during maturity and more temperature during field emergence, vegetative and flowering. Because of more favorable weather conditions and less aphid infestation crop growth and seed yield were relatively more in the first sown crop as compared to late sown crop.
