Abstract

The agrometeorological data of toria (variety M-27) at Jorhat and Shayamakhunta for the period 1986-87 to 1992-93 were used for assessing phenological development in relation to heat unit, water use, photothermal  and heliothermal unit and photosynthetically active radiation (PAR) requirement at Shayamakhunta and Jorhat.  Photothermal, heliothermal unit,  water use and PAR were higher at Shayamakhunta than that of Jorhat. Heat use efficiency (HUE) and radiation use efficiency (RUE) also showed variations in time and space which were comparatively higher in early sown crops. A curvilinear relationship between duration (days) and heat units was derived seperately for sowing to flowering and pod formation to physiological maturity stages which showed consistent positive correlations at both locations.
