Yield Performance of Cabbage Under Different Combinations of Manures and Fertilizers

Abstract

An investigation was made on yield performance of cabbage (Brassica oleracea var. capitata) under different combinations of manures and fertilizers at Hogladanga village under Botiaghata upazila, Khulna during the period from November, 2013 to March, 2014. The experiment was carried out in a Randomized Complete Block Design (RCBD) with three replications. The experiment consisted of seven treatments. The treatments were T₁ = recommended doses of NPK (urea @ 350 kg ha⁻¹, TSP @ 250 kg ha⁻¹, MoP @ 300 kg ha⁻¹, respectively), T₂ = cowdung @ 10 t ha⁻¹, T₃ = vermicompost @ 10 t ha⁻¹, T₄ = Trichoderma compost @ 10 t ha⁻¹, T₅ = 50% cowdung + 50% recommended doses of fertilizer, T₆ = 50% vermicompost + 50% recommended doses of fertilizer and T₇ = 50% Trichoderma compost + 50% recommended doses of fertilizer. The growth and physio-morphological characteristics, yield attributes and yield were positively and significantly influenced by the application of vermicompost with recommended dose of NPK and also cowdung compost with the recommended dose of NPK. In most cases, 50% vermicompost + 50% recommended doses of fertilizer receiving treatment performed better. However, the maximum yield of cabbage (57.16 t ha⁻¹) was obtained from the treatment receiving 50% vermicompost + 50% recommended doses of fertilizers and the lowest yield of cabbage (38.48 t ha⁻¹) was obtained from the control. But considering the highest benefit-cost ratio of cabbage (3.63) was noted when applied 50% cowdung + 50% recommended doses of fertilizer was applied for sustainable crop production.
