The Ramon Magsaysay Center for Agricultural Resources and Environment Studies (RM-CARES) has isolated Thrichoderma longibrachiatum and Thrichoderma asperellum from carabao manure. Since Thrichoderma is mass produced solid form and applied basally, the conversion of Thrichoderma into liquid form allows the supply of nutrients at different growth stages of crops.
The study aimed to formulated to test the efficacy of combined organic liquid (OLS) from Thrichoderma spp and fermented extracts from kakawate and malunggay leaves, banana fruits, soybean and mungbean seeds. Based on the results for one trial on pechay, undertaken in a certified organic area in Ramon Magsaysay Center for Agricultural Resources and Environment Studies (RM-CARES), Central Luzon State University, Science City of Munoz (CLSU), Nueva Ecija, yield was significantly increased by the supplementation of Thrichoderma spp in combination with fermented plant and seed extracts. Treatment with 1:0.5 ratio of T.asperellum: fermented plant and seed extracts significantly gave the highest computed yield of 12 t/ha which is 47 % higher that the yield obtained in commercial OLS and 106 % higher than the control. The treatment with 1:0.5 ratio of T. longibrachiatum: fermented plant and seed extracts, and treatment with commercial OLS produced comparabl;e yield with 9.80 t/ha and 8.17 t/ha, respectively. Since the developed OLS from Trichoderma and fermented plant and seeds extracts is at par or even surpassed the yield of commercial OLS, it has the potential as bio-liquid fertilizer for organic pechay production which could be possibly substituted to commercial OLS.
