This study evaluated the productivity of traditional upland rice and legume intercrops planted singly and in combinations under a coconut-based farming system. A split-plot design composed of two factors with three replications was used. The main plots were traditional upland rice varieties (Kalutak, Malido, Mansanaya, San Pedro, and PSB Rc 10 as check variety) while sub-plots were legume intercrops (peanut, mungbean, soybean, and no intercrop as control). Growth and yield of crops and return on investment (ROI) were gathered to determine productivity. Results revealed that Malido with no intercrop produced the tallest plant, while most tillers were from plots without intercrop. Highest dry grain yield of rice (1.42 t ha-1) was taken from plots grown to San Pedro with no intercrop. Highest dry grain...

Thus, this research was designed to determine sugarcane production related constraints of selected soils in Negros Island and to recommend management strategies to address these constraints.Suitability analysis was done following the FAO suitability analysis scheme. Results of suitability analysis served as basis in identifying constraints of a particular soil type when used for sugarcane production. Results revealed that all the 19 soil types used for sugarcane production in Negros Occidental were classified as marginally suitable according to the FAO scheme because of the existence of one severe limitation. The most common constra...

Highest dry grain yield of rice (1.42 t ha-1) was taken from plots grown to San Pedro with no intercrop. Highest dry grain yield of legumes was from plots with Mansanaya + soybean (0.94 t ha-1) and PSB Rc 10 + mungbean (0.92 t ha-1). Highest ROI (344.40%) was from plots with PSB Rc 10 + mungbean.

Twelve treatments were imposed including no fertilization, with full fertilization using inorganic fertilizer, and with full fertilization + lime. The recommended N rate (RRN) was reduced to 75, 50 and 25% with subsequent application of mud press to satisfy the full RRN. Bagasse ash at 10 t ha-1 and microbial inoculant were likewise used to supplement the nutrient sources. Standard cultural practices for sugarcane production were followed. Cane yield and NPK use efficiency indices were determined and analyzed to come up with a judicious fertilization program. Integrated nutrient management practices including mudpress, bagasse ash and microbial inoculant improved cane yield, partial factor productivity and agronomic efficiency of applied N, and physiological efficiency of applied P. Application of lime resulted to better partial factor productivity and apparent recovery efficiency of applied P. Combined use of inorganic fertilizer and mudpress enhanced partial factor productivity of applied K, while addition of bagasse ash and microbial inoculant increased physiological efficiency of applied K.
