Abstract
The relationship between the ratio of actual evapotranspiration (ET) and pan evaporation (EP) with the leaf area index (LAI) of pigeon pea (Cojonus cajan cv. GT-lOO) at Anand was studied during 1992 and 1993. The peak values of ET and LAI. during 50% flowering to pod developl11ent stage of the crop. were 8.6 mm per day and 4.74. respectively. The linear relationship between one another was observed at the same til11e (R2 =0.70). The 50% flowering phase of the crop was found to be critical phase of water requirement in pigconpea. The seasonal ET and the water-use efficiency of the crop were 819 mm and 4.1 kg ha-1 mm-1 respectively.Downloads
