Item Performance of corn (Zea may Linn.) to the application of mudpress-based organic fertilizerMacarayan, Olympio B.; Campaner, Alexander M.; Mercado, Marcelina Fe G.; Fuentes, Augie E.; Revilla, Nila Nanette S. (Davao del Sur State College (Formerly SPAMAST Digos Campus), 2013)The developed mudpress-based organic fertilizer (MBOF) had been tested to corn following the Fertilizer and Pesticide (FPA) protocol. The trial was conducted in Brgy. Dulangan, Digos City. Corn ear length and number of corn ears per plant were not affected by the fertilizer application. However, plant height, ear diameter, fresh weight of corn ear, dried weight of corn ear, weight of kernel after drying and computed yield were significantly improved by the application of inorganic and MBOF or their combinations. Positive response of corn was noted among these variables, thus, MBOF can be utilized as an ideal organic fertilizer.Item Effect of GREENTEC organic fertilizer on the yield of pechay (Brassica chinensis)Macarayan, Olympio B.; Campaner, Alexander M. (Southern Philippines Agri-business and Marine and Aquatic School of Technology, 2004-01)This study was conducted in the farmer's field of Barrio Pampanga, Lanang, Davao City from the period February to April 2001. It aimed to generate information on the agronomic effectiveness of 20 bags per hectare GREENTEC organic fertilizer and to evaluate the growth and yield response of pechay to different rates and combinations of GREENTEC organic and inorganic fertilizers. Results showed that growth of pechay in T5 (20 bags per hectare of GREENTEC organic fertilizer alone) was comparable to that in T2 (Ammophous - 3 bags/ha + Ammosul -12 bags/ha + Muriate of Potash-0.5 bags/ha), T3 (Amorphous -11/2 bags/ha + Ammosul - 6 bags/ha + Muriate of Potash - 0.5 bag/ha; T4 (T3 + T5) and T6 (T2 + T5) but much higher compared to T1 (no fertilizer). The yield of pechay in T5 was comparable to that of T2 and T3 but significantly higher compared to the yield of pechay in T1. By mixing 20 bags GREENTEC organic fertilizer per hectare with inorganic fertilizer rates in T2 and T3, highly significant increase in yield of pechay was observed (T6 and T4).Item Performance of corn (Zea may Linn.) to the application of mudpress-based organic fertilizerMacarayan, Olympio B.; Campaner, Alexander M.; Mercado, Marcelina Fe G.; Fuentes, Augie E.; Revilla, Nila Nanette S.
