SEASONAL-VARIATIONS IN SOME PHYSIOLOGICAL CHARACTERS OF SESAME (SESAMUM-INDICUM L)

Some physiological parameters and seed yield and its components of two varieties of sesame grown in rabi and kharif seasons were evaluated. Chlorophyll content in leaf, leaf area index (LAI), and crop growth ra te (CGR) of both the varieties were recorded higher in kharif as compa red to rabi. The higher seed yield in kharif was associated with incre ased number of capsules per plant, bigger capsule size, higher seed we ight per plant and also higher harvest index. In kharif, the higher se ed yield influenced through higher CGR, LAI, chlorophyll content and p revailing higher solar radiation as well as higher air and soil temper ature.
