Efficacy of Bio-Fertilizers and in Combination with Chemical Fertilizers on Growth of Okra [Abelmoschus esculents (L.) Moench]

Abstract

The present experiment was conducted at Horticultural Research Farm, Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow (U.P) during 2016-17. The experiment was conducted in a Randomized Block Design with ten treatments replicated thrice. The experiment comprises of different doses of biofertilizers i.e. Control, RDF (100%) , Azotobacter (100%) , Phosphate Solubilizing Bacteria (PSB) 100%,50% RDF + 50% Azotobacter, 50% RDF + 50% PSB, 50% Azotobacter + 50% PSB, 75% RDF + 25% Azotobacter, 75% RDF + 25% PSB, 25% RDF + 75% Azotobacter, 25% RDF + 75% PSB.The treatments include different basal application of NPK & bio-fertilizer on growth of Okra. The growth attributing characters were recordedmaximum height of plantT1 (126.20 cm),number of leaves/ plantT1 (44.61),diameter of stemT1 (128.36 mm),earliest flowering formationT1(33.43) days,highest number of flower / plant T1 (20.31),earliest fruit formation T1(37.55),number of branches / plant T1(6.30),produced maximum number of fruits / branch T1 (12.33),number of fruit / plant T1(21.42),maximum length of fruit T1(13.64 cm), maximum girth of fruit T1(1.85cm) and maximum weight of fruit T1(12.47 g).
