“…Poor understanding of the N-balance between applied Nfertilizer amounts, N (uptake) by plants, N (immobilized) in the soil matrix is one of the main reasons leading to overuse of N-fertilizers and subsequently to N (leached) . High concentrations and excessive use of human urine during fertigation may lead to Na-accumulation in soils (Sene et al, 2013;Sheneni et al, 2018) thus, inhibiting plant growth. Furthermore, excessive use of human urine may also increase the risks of NO 3 leaching and electric conductivity (EC).…”

This study simulated the biophysical, economic and environmental implications of cowpea fertigated with human urine (equivalent to 60 kg N ha-1) as source of organic N. The DSSAT CROPGRO model was used to simulate harvested cowpea yield, N (leached) , N (uptake) , monetary returns or gross margins in ($) under two different treatments: without fertigation or human urine (T 0) and with fertigation (T 1). Biophysical analysis using the Cumulative Probability Distribution (CPD) showed a 50% probability of the harvested cowpea yield under T 1 being higher than under T 0 at 1060 and 600 kg ha-1 respectively, accounting for a 43.4% difference. The Mean Gini Stochastic Dominance (MGSD) analysis was used to assess the gross margin and helped in deciding on the best strategic and management option. The findings of this study revealed a 50% probability (CPD 0.5), of higher gross margin under T 1 at $-215 higher than under T 0 at $285. This was a $70 difference per season under T 1 and so enhancing a faster payback and a larger monetary return on overall investments. Similarly, seasonal analysis with fertigation showed that at CPD 0.5 , the N (leached) was still < 4 kg N ha-1 per season and so posed no environmental risks. The simulation results also showed higher a probability of N (uptake) of about 270 kg N ha-1 during fertigation compared to about 95 kg N ha-1 under T 0. Therefore, the DSSAT CROPGRO model can be used to successfully forecast future cowpea yields, gross margin, N (leached) , N (uptake) under different management practices to enable smallholder farmers in South Sudan make informed decisions on sustainable cowpea production.

Background: The nutrient is one of the most important elements for plants. Lack of nutrients cause thegrowth and yield will not be optimal. The use of organic liquid human urine and NPK fertilizer are a source of micro and macronutrients to increase the yield of black cute rice. Objective: This study aims to determine the best treatment combination of human urine and NPK fertilizer dose to maximize the yield of black cute rice. Methods: The research was arranged in a randomized complete block design (RCBD) with two factors and three replications. The first factor was dose of human urine fertilizer, which consisted of three levels, namely, 0, 500, and 1000 L ha-1. The second factor was the dose of NPK fertilizer, which consisted of three levels, namely, 0, 150, and 300 kg ha-1. Results: The results showed that a combination of organic liquid human urine and NPK fertilizer could increase the productive tillers number, canopy dry weight, and grain dry weight of black cute rice. The highest grain dry weight was found at the combination between ferlilizer dose of human urine of 1,000 L ha-1 and NPK of 300 kg ha-1 and yielded the maximum grain dry weight of 8.633 t ha-1 in Litosol soil. Conclusion: The research fundings that the combination between human urine of 1,000 L ha-1 and NPK of 300 kg ha-1 can maximize the yield of black cute rice. For future research, we recommend that the combination between human urine of 1,000 L ha-1 and NPK compound of 300 kg ha-1 can use in other rice varieties.
