ABSTRACT

A field experiment was conducted at Horticulture Research Farm Malakandher, Khyber Pakhtunkhwa Agricultural University Peshawar, during summer 2010 to evaluate the impact of nitrogen and phosphorus on seed yield and yield components of Okra cultivars. The experiment was laid out in Randomized Complete Block Design with split plot arrangement having three replications. Cultivars were allotted to the main plots, while various levels of nitrogen and phosphorus were kept in the subplots. Urea and single superphosphate (SSP) were used as source of nitrogen and phosphorus, respectively. Germination percentage (%) and seed yield (kg ha-1) were significantly different with respect to cultivars. Maximum germination percentage (89 %) was observed in variety Arka Anamika, and maximum seed yield (1311 kg ha-1) was recorded in variety Green Star. Significant response of various levels of nitrogen and phosphorus were observed in number of pods plant-1 and seed yield (kg ha-1). Maximum number of pods plant-1 (10.69) and maximum seed yield (1374.9 kg ha-1) were reported in plots having received both 150 kg N/ha and 90 kg P/ha. A non significant difference was observed in parameters i.e. number of seeds pod-1 and 1000 seed weight (g). It is concluded that Okra variety Green Star and application of N and P (at rates of 100 kg N ha-1 + 60 kg P ha-1) in combination resulted in higher seed yield of Okra.
