EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON GROWTH AND YIELD OF CUCUMBER (Cucumis sativus L.) IN WINTER SEASON

Abstract

The experiment was conducted in the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to investigate the effect of integrated nutrient management on growth and yield of Cucumber in winter season during the period of October 2019 to March 2020. The experiment consisted of single factor. The experiment was conducted in randomized complete block design (RCBD) Using thirteen treatments and replicated three times. The treatments used were T 0 =Absolute control, T 1 = N 75kg/ha P 60kg/ha K 50kg/ha (RDF 50%), T 2 = N 75kg/ha P 60kg/ha K 50kg/ha (RDF 50%) + Vermicompost (3ton/ha), T 3 =N 75kg/ha P 60kg/ha K 50kg/ha (RDF 50%) + Vermicompost (3t/ha) + Bio-fertilizer (67 kg/ha), T 4 =N 75kg/ha P 60kg/ha K 50kg/ha (RDF 50%) + Vermicompost (3t/ha)+ Bio-fertilizer (67 kg/ha) + Neem oil cake (40 kg/ha), T 5 = N 112.5kg/ha P 90kg/ha K 75kg/ha (RDF 75%), T 6 =N 112.5kg/ha P 90kg/ha K 75kg/ha (RDF 75%) + Vermicompost (3t/ha), T 7 = N 112.5kg/ha P 90kg/ha K 75kg/ha (RDF 75%) + Vermicompost (3t/ha) + Bio-fertilizer (67 kg/ha), T 8 = N 112.5kg/ha P 90kg/ha K 75kg/ha (75%) + Vermicompost (3t/ha) + Bio-fertilizer (67 kg/ha) + Neem oil cake (40 kg/ha), T 9 = N 150kg/ha

K 100kg/ha (RDF 100%), T 10 = N 150kg/ha P 120kg/ha K 100kg/ha (RDF 100%) + Vermicompost (3t/ha), T 11 = N 150kg/ha P 120kg/ha K 100kg/ha (RDF 100%) + Vermicompost (3t/ha) + Biofertilizer (67 kg/ha) and T 12 = N 150kg/ha P 120kg/ha K 100kg/ha (RDF 100%) + Vermicompost (3t/ha)+ Bio-fertilizer (67 kg/ha) + Neem oil cake (40 kg/ha). In this study different treatments showed significant variations on most of the parameters. The highest number of fruits per plant (17.0), individual fruit weight (181.67g) and fruit yield (34.32 t/ha) was recorded from T 12 .Whereas the lowest number of fruits per plant (8.51), individual fruit weight (120.62 g) and fruit yield (11.44 ton/ha) was recorded from treatment T 0 (control). The results revealed that there were significant difference between the application of nutrients and bio-fertilizers for yield and yield component traits. So, the economic analysis revealed that the maximum benefit cost ratio (3.03) was noted from T 12 and the lowest (1.50) from T 0 P 120kg/ha treatment.
