Enhancing Yield and Profitability of Peanut (Arachis hypogaea L.) to Application of Different Organic Foliar Fertilizer

Abstract

One strategy to produce enough, healthy, and safer products is to apply the best practices by using locally produced organic bio-fertilizer as nutrients for the crops. This study aimed to evaluate the effects, determine the appropriate, and assess the profitability of using locally produced organic foliar fertilizers on peanut production. The treatments designated as follows: T1 = Control (no application), T2 = Power grow 100 ml/16li H2O, T3 = Vermi tea 100 ml/16li H2O, T4 = Poultry litter tea100 ml/16li H2O, and T5 = Wood vinegar 100 ml/16li H2O. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Each replication was divided into five (5) treatment plots measuring twelve (12) m2 separated by 1 m alleyways between replications and treatment plots to facilitate farm operations and data gathering. The treatment plants were sprayed with foliar fertilizer six times at weekly intervals, starting two weeks up to the pick of the peanut plants' last flowering. Results showed that peanut plants flowered early when applied with poultry litter tea but obtained a high leaf area index (LAI) and weight of 1,000 seeds (g) when applied with Power grow foliar fertilizer. Application of poultry litter tea obtained the highest seed yield of 1.470 t ha-1 and achieved the highest gross margin of PhP48,965.00 ha-1. Control plants (no application) obtained the lowest seed yield of 0.87 t ha-1, which led to a lower gross margin of PhP18,750 ha-1. In terms of pest incidence, no serious presence of insects and diseases were noted; thus, a high to moderate resistance rating was obtained in all treatment plants.
