An experiment was carried out at Agricultural Meteorology Department farm, College of Agriculture, Vasantrao NaikMarathwada Krishi Vidyapeeth, Parbhani, during kharif season 2016. The field experiment was laid out in the split spot design with three replication and treatment combination of four sowing dates viz., D1 (27 MW), D2 (28 MW), D3 (29 MW) and D4 (30 MW) as main plot and four genotypes Phule til -1,Gujarat -2, JLT -408 and JLT -7 as sub-plot treatment. The crop was sown with spacing

... 5 cm on 5.4 x 4.0 m 2 gross plot size and 4.5x3.6 m 2 net plot size. Among the Sowing dates and varieties, the variety JLT -408 when sown during 28 th MW was significantly superior over the other varieties and sowing dates. The result of the study indicated that correlation of rainfall, rainy day, RH-II at P1 (Sowing dates to vegetative), P2 (vegetative to reproductive) and rainfall, rainy day, RH-I, RH-II at P3 (reproductive to maturity), P4 (maturity to harvesting) stage was positively correlated with sesamum yield. Tmaxi., Tmini was negatively correlated with sesamum yield at all phases expected Tmini at P3 stage in variety JLT -408.
