Effect of Nitrogen and Biofertilizer on Yield and Quality of Okra Hybrids

摘要

A field experiment was conducted during rainy seasons of 2003 and 2004 on okra [Abelmoschus esculentus (L.) Moench] at Horticulture Farm, S. K. N. College of Agriculture, Jobner, Rajasthan to study the effect of nitrogen fertilization and biofertilizers on yield attributes, yield and quality of okra. Hybrid Varsha produced higher leaf area at 1st and last picking, branches/plant, fruit/plant, fruit yield, protein and crude fibre content compared to Barkha Battu but remained on par with Hybrid Ganga. Inoculation of okra seed with Azospirillum significantly increased leaf area, branches/plant, fruit/plant, fruit yield, nitrogen, protein content in okra seed and available soil N over no inoculation. Application of 25% N through urea + 75% through vermicompost produced significantly higher leaf area, branches/plant, fruit/plant, fruit yield, nitrogen and protein content over control. However, maximum available N was recorded in 100% vermicompost followed by 25% N through urea+75% N through vermicompost over control, farmers' practice, 100%N through urea and 75% N through urea+25% N through vermicompost.
