RESPONSE OF SESAME TO IRRIGATION SCHEDULING AND N FERTIGATION LEVELS
Keywords:Irrigation schedules, Fertigation, Sesame, Water use efficiency
A field experiment was conducted on sesame during summer season of 2010-11 and 2011-12 on red sandy loam
soil of Northern Telangana zone of Telangana, India to find out the combined effect of irrigation and N levels
through fertigation on growth, yield attributes, yield and quality of sesame with Swetha til variety. The treatments consisted 15 possible combinations of 5 levels of irrigation as main plot and 2 levels of N in sub-plot in split-plot design. The results revealed that drip irrigation scheduled at 100% Epan and application of 50% recommended dose of nitrogen (RDN) through fertigation to sesame recorded significantly higher number of effective branches/plant, length of capsule, number of capsules/plant, number of seeds/capsule, seed and stover yields, Harvest index (HI), 1000-seed weight, oil content, oil yield and NPK uptake compared to surface irrigation scheduled at 1.0 IW/CPE ratio and 0% N application applied through fertigation. Maximum WUE was also recorded with 100% Epan irrigation and application of 50% RDN. Interaction effect was found significant with plant height, LAI, dry matter production, seed yield/plant; seed, stover and oil yield, HI and total NPK uptake.
