ABSTRACT
Experiments were conducted to study the effect of different irrigation levels i.e. (35%, 45% and 55 % depletion of maximum available water) and irrigation timings i.e. (Morning, Noon and Evening) on growth and yield of broccoli at Horticulture Research Farm, The University of Agriculture Peshawar during the growing season in 2016-17 and repeated in 2017-18. The experiment was laid out in Randomized Complete Block Design (RCBD) with split plot arrangement. Irrigation timings were kept in main plot, while irrigation levels in sub plot. Two years average results revealed that irrigation timings, levels and their interactions had significant effects on growth, yield and quality parameters of broccoli. Broccoli plants irrigated early in the morning resulted in early curd formation (66.8), maximum plant height (45.21cm), leaves plant-1 (15.84), leaf weight (11.00 g), primary curd weight (340.94 g), secondary curd weight (189.50 g), primary curd diameter (8.60), secondary curd diameter (7.56cm), curds plant-1 (8.73), yield (8.03 t ha-1) and survival (92.67 %) than rest of the treatments. As for as irrigation level is concerned, irrigation at 35 % rate resulted in in early curd formation (66.44 days), maximum plant height (47.54 cm), leaves plant-1 (15.88), leaf weight (11.24 g), primary curd weight (344.48g), secondary curd weight (192.88 g), primary curd diameter (8.70cm), secondary curd diameter (7.69 cm), curds plant-1(8.50), yield (8.44 t ha-1) and survival (92.33 %) than rest of the treatments. Regarding interactions majority of the growth and yield parameters showed best results in morning time irrigation @ 35 % depletion level. Irrigation with 35% depletion of maximum available water produced higher yield and yield components as compared to other treatments. Morning irrigation increased growth, yield and quality components of broccoli. Therefore, it is recommended that the broccoli plants should be irrigated with 35 % depletion of maximum available water to obtain best growth, yield and quality under the agro-climatic condition of Peshawar-Pakistan at the morning.
