Demonstration of Integrated Applications of Site Specific NPS Fertilizer Recommendation with Vermicompost for Bread Wheat Production in the Burka Jiren Watershed Under Lime Condition

Degradation of physical properties caused as a result of the loss of soil organic matter and reduced presence and activity of soil organisms also occur in heavily polluted soils. The addition of vermicompost is used to increases organic matters in the soil. Therefore, this study was conducted to demonstration of integrated applications of site specific NPS fertilizer recommendation with vermicompost for Bread wheat production in the Burka Jiren watershed under lime condition. The experiment was implemented during 2024 crop season in Gechi district at Burka Jiren community watershed. The treatments was consisted two level; namely (T1) Blanket Recommendation (1:1 ratio of urea and NP respectively) and (T2) 1/2 Recommended vermicompost + 1/2 recommended N + recommended NPS). The collected data was analyzed using T-test and interpreted as mean and standard deviation by SAS software version 9.0. Results indicated that the grain yield of bread wheat was significance (P<0.05) influenced between two treatments. The highest grain yield (47.224 qt/ha) was recorded from treatment two which treated by 1/2 Recommended vermicompost + 1/2 recommended N + recommended NPS). However the lowest grain yield (23.625 qt/ha) was obtained from blanket recommendation of NPS fertilizer alone. The integrated use of Vermicompost with NPS fertilizer significantly increased the mean of soil pH from 5.0 to 5.26. Both treatments presented similar levels of organic carbon and total nitrogen. Farmers in the Burka Jiren community watershed should consider integrating agricultural lime with site specific NPS fertilizer to mitigate soil acidity and enhance crop productivity.
