| Abstract | ||
| Two field trials were conducted at Sakha Horticultural Research Station Farm during the successive summer seasons of 2012 and 2013. The aim of the present study was to evaluate the effect of three nitrogen fertilization levels (60, 30 and 15 Kg N fed-1) and two biofertilizer inoculation methods (liquid and tablets) on okra (Eskandrani var.) growth, yield and pods quality. 60 kg N fed-1 and liquid biofertilization method had the highest values of number of leaves / plant (36.19 and 37.52), stem length (96.84 and 110.14 cm), leaf area (409.93 and 425.8 cm2 ), leaf dry weight (21.09 and 21.2 %), number of pods plant-1 (69.41 and 77.38), early yield (2.24 and 2.66 ton fed-1) total yield (6.156 and 6.536 ton fed-1) and nitrate concentration in okra dry pods (102.4 and 123.2 mg kg-1). The interaction between application of 25% of the recommended nitrogen and tablets biofertilizer inoculation method had the lowest values of the previous parameters. Increasing nitrogen fertilization levels led to increase P% in okra leaves and pods either with or without biofertilization. Increasing nitrogen levels plus biofertilizer led to increase No3 in leaves and pods. | ||
