Abstract

Mudpress is considered as rejected waste material of sugarcane industries that cause problem of storage and pollution to surrounding of sugar mills on its accumulation are available in sugarcane milling plant hence, it can be utilized as source of organic fertilizer combined with inorganic fertilizer to agronomic crops. This study aimed to evaluate the effects, determine the optimum rates and assess the profitability of combined application of mudpress and inorganic fertilizer in mungbean production. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three (3) replications. T1–no fertilizer (control); T2–30-30-30 kg ha-1 N, P2O5, K2O; T3–10 t ha-1 mudpress; T4–7.5 t ha-1 mudpress + 7.5 kg ha-1 N, P2O5, K2O; T5–5.0 t ha-1 mudpress + 15.0 kg ha-1 N, P2O5, K2O; T6–2.5 t ha-1 mudpress + 22.5 kg ha-1 N, P2O5, K2O. Results revealed that plants applied with recommended inorganic fertilizer at 30-30-30 kg ha-1 N, P2O5, K2O (T2) and applied with 50-75 % inorganic fertilizer (T5 and T6) and without fertilizer application matured early compared to plants applied with pure organic mudpress at 10 (t ha-1) and 7.5 (t ha-1). Likewise, plants applied with 75-100% mudpress as fertilizer had the lowest fresh herbage yield comparable to the plants not applied with any fertilizer. On the other hand, highest number of seeds per pod (19-21 seeds/pod) was observed in plants applied with 50-100% inorganic fertilizer as compared to plants not applied and applied with 75-100 % mudpress. Pests response of mungbean Pagasa 19 variety had high to moderate resistant to insect pests and diseases. Highest net income ha-1 of Philippine Peso (PhP) 73392.00 was achieved with plants applied with (100%) inorganic fertilizer at the rate of 30-30-30 kg ha-1 N, P205, K20. Among the combined treatments, application of 5.0 t ha-1 + 15 kg and 2.5 t ha-1 + 22.5 and kg N, P205, K20 ha-1 (25-50% organic + 50-75% inorganic fertilizer) gave higher net income of PhP 63812.00 and PhP 52624.00, respectively.
