영어 초록
A field experiment was conducted at Chishaka, Wedza district in the province of Mashonaland East, Zimbabwe during the 2020/2021 cropping season to determine effect of integrated nutrient management (INM) on cabbage (Brassica oleracea var. capitata) yields, net returns, and residual soil fertility. A total of six treatments were evaluated in a randomised complete block design (RCBD) with five replications. Treatments comprised T1 (control, 100% recommended chemical fertilizer), T2 (25% Cattle manure + 25% Chicken manure + 50% Ammonium nitrate), T3 (50% Compound S + 50% Chicken manure), T4 (50% Compound S + 25% Goat manure + 25% Chicken manure), T5 (farmer practice, 75% Compost + 25% Chicken manure), and T6 (50% Compost + 50% Chicken manure). All rates of organic manures were applied based on N equivalence. The soil was sandy loam with low soil organic carbon (1.28%), nitrogen (0.175%), and phosphorus (6.59 mg/kg) for all experimental plots. Results indicated that INM significantly improved soil and crop productivity. INM treatments T4, T3, and T2 recorded significantly maximum yield and yield components which were statistically at par. These treatments also gave the best strategy to improve major soil nutrients and maintain soil fertility. Similarly, the maximum net profit was obtained from combined application of treatments T4, T3, and T2. Treatment with 100% chemical fertiliser gave relatively lower yields and net benefit value than T4, T3, and T2. These results indicate that INM has the great potential to reduce the use of chemical fertilisers without decreasing soil fertility or crop yields. Therefore smallholder resource constrained farmers can adopt INM as a strategy, to enhance resource use efficiency and sustain soil health and crop productivity for improved livelihoods.참고 자료
