Influence of Direction of Sowing on Radiation-use Efficiency of Pearl millet

Abstract

Field experiments were conducted at the Indian Agricultural Research Institute, New Delhi, during kharif seasons of 1992 and 1993 to study the effect of direction of sowing on the radiation-use efficiency during different growth ststages of three pearl millet cultivars (Pennisetum glaucum (L.) R.). Efficiency of radiation ntutilization in dry matter production was maximum in HHB-67 and minimum in variety HHB-60. Sowing the crop in a north-south direction improved the radiation-use elefficiency by 0.21 g MJ^-1 over an east-west sown crop.
