Abstract:
The field experiment was carried out at the Instructional Farm, Jaguli, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia (W.B.) to study the effect of irrigation and mulching on yield attributes and yield of safflower chickpea intercropping system during two consecutive winters of 2010-11 and 2011-12. The soil was sandy loam in texture with medium fertility status. The soil pH was 6.85, organic carbon (%) and total N (%) were 0.58 and 0.07, and available P2O5 and available K2O were 25.45 and 178.95 kg ha-1, respectively. The experiment was laid out in a split-split plot design, replicated thrice, having 3 irrigation treatments as main plots, viz., I1 - rainfed, I2 - Irrigation at 0.5 IW: CPE ratio, I3 - irrigation at 0.75 IW: CPE ratio and 2 cropping system in sub-plots viz. C1 - Sole safflower, C2 - Safflower-chickpea has grown as 3:2 row ratio, respectively, and 2 sub-sub plot treatments, viz., M0 - No mulching, M1 - Straw mulching. The results showed that irrigation at 0.75 IW: CPE ratio i.e., I3 recorded higher values of plant height, final dry matter accumulation (g m-2), leaf area index, and crop growth rate (g m-2 day-1) of safflower. Safflower-chickpea grew a 3:2 row ratio, i.e., C2 gave the highest values of all growth attributes of safflower, and straw mulching gave a better result than no mulching. The highest values of seed yield (1159 kg ha-1), oil content (28.17 %), and oil yield (326.8 kg ha-1) of safflower were obtained under irrigation at IW: CPE of 0.75, i.e., I3. Among the cropping systems, intercropping safflower gave a better result than sole safflower, and straw mulching gave a better result than no mulching.
