Effect of Different Doses of Nitrogen and Phosphorus on Growth of Okra (Abelmoschus esculentus L. Moench) cv. Arka Anamika

Abstract

Background: A field experiment was conducted to know the effect of different doses of nitrogen and phosphorus on growth of okra (Abelmoschus esculentus L. Moench) cv. Arka anamika was carried out at Horticultural Farm of Palli-Siksha Bhavana (Institute of Agriculture), Visva-Bharati, Sriniketan, West Bengal during 2020. The experiment was laid out in a RCBD (Randomized complete block design) consisting of twelve treatments with 3 replications. Treatments included were four levels of nitrogen (0, 100, 120 and 140 kg N/ha) and three levels of phosphorus (0, 80 and 100 kg P/ha). The statistical analysis indicated that growth was significantly influenced with application of nitrogen and phosphorus. The characters plant height, number of branches per plant, first flowering, fifty percent of flowering, fruit length, fruit diameter exhibited best results with the treatment N3P2 (140 kg N ha + 100 kg P ha). Present investigation, therefore, indicated better response of the plants towardsapplication of 140 kg/ha nitrogen and 100 kg/ha phosphorus which was found to be most remunerative with regard to their growth of okra.
