Abstract: The experiment “Effect of sowing time and type of mulching on the growth, yield and quality of okra” was conducted at Agriculture Research Institute Tarnab, Peshawar during 2016. The experiment was designed in Randomized Complete Block with split plot arrangements, replicated thrice. Sowing dates were assigned to main plots, while mulching materials were kept in sub-plot. The seeds of okra cultivar “Sabz-Pari” were sown at three different dates i.e. 15thApril, 30th April and 15th May. Three different types of mulch materials (Black plastic, Transparent plastic and Alsy straw (Organic mulch) were used and compared with control (no mulch). Higher germination percentage (79.6), more pods plant-1 (24.2), seeds pod-1 (72), 1000 seed weight (92 g), pod yield plot-1 (10.2 kg) and yield tones ha-1 (11.3) were recorded in plants sown on 30th April. Maximum plant height (143.7 cm) was observed in plants sown on 15th April while the 15th May plantation showed early emergence (6.1 days) of seedlings, early flowering (42.3 days) and maximum leaves plant-1 (32). In response to mulching, early emergence of seedlings (5 days), maximum plant height (138.9 cm), leaves plant-1 (39.3), number of pods plant-1 (25.3), yield plot-1 (10.8 kg) and yield tones ha-1 (12) were recorded in plants mulched with Transparent plastic. Higher germination percentage (87.96), seeds pod-1 (68.3), 1000 seeds weight (88.3 g) and early flowering (44.4 days) were recorded in plants mulched with Black plastic. It can be concluded that when the seeds of okra were sown on 30th April and mulched with Transparent plastic, it gave good response regarding growth, yield and quality.
