Abstract

Field experiments were conducted during Kharif 1992 and 1993 at the Regional Research Station, Vridhachalam to evaluate the effect of different dryland technologies individually and in combination on the yield attributes and the yield of sesame (TMV4) under rainfed conditions. The results of the study revealed that combination of all the dryland technologies viz, seed treatment with 2 per cent KH2PO4, and Azospirillum, forming broad bed and furrows, application of composted coirpith, application of enriched FYM with 75 per cent or recommended dose of fertilizer, pre sowing incorporation of fluchloralin 1 kg/ha +1 hand weeding increased the plant height, root length, number of branches per plant, number of capsules per plant and the grain yield of sesame over farmer's practices, and the other individual dryland technologies. The increased yield by the combination of different dryland technologies was 82.7 per cent over control. All the individual dryland technologies also increased the yield over farmer's practices.
