Effect of varying levels of NPK on growth and yield of bottlegourd in southern dry region of Karnataka

摘要

Studies on response of bottlegourd cv. Arka Bahar to varying levels of NPK showed that, nitrogen significantly increased the vine length, number of leaves per vine, number of branches per vine, vine girth, number of male flowers per vine, number of female flowers per vine, total dry weight of plant and ultimately yield and the crop was highly responsive to it. Phosphorus also showed positive influence on various characters. Whereas, application of varying levels of potassium had no significant effect except on vine length and number of leaves per vine with application of nitrogen, phosphorus and potassium at 120:100:30 kg/ha, respectively recorded the maximum yield and appeared to be optimum fertilizer dose under southern dry zone of Karnataka to bottlegourd cv, Arka Bahar.
