An integrated soil fertility management or ISFM on-farm trial was conducted at Barangay Tawan-tawan, Baguio District, Davao City in 1993 to 1999 to know the effects of  organic and inorganic fertilizers on the vegetative growth, nutrient status and yield performance of intercropped Catigan dwarf x Laguna tall (CATD x LAGT) coconut  hybrid better known as PCA 15–1 or  CATLAG.   Vegetative growth  of CATD x LAGT palms  revealed that ammonium sulfate + NaCl and goat manure + NaCl   produced significantly bigger girth size on the first year and more number of leaves and living fronds on the second and fourth year, respectively. These treatments also enhanced early flowering (>50% @ 4.5 years) and yield (51-53 nuts/tree/yr @) 5 years from field planting) in hybrid palms.  The organic fertilizers, i.e. goat manure and coconut husk, become more effective in their effect on the vegetative and reproductive characters of palms when combined with a Cl source (NaCl).  The application of Cl nutrient contributed to the better performance of palms during the drought condition. The application of goat manure resulted in improved levels of soil nutrients as K, Ca, Mg and P, increased percent base saturation and lower soil acidity.   The use of local hybrid, PCA 15-1 and ISFM-based low cost production inputs such as ammonium sulfate, goat manure/coco waste (husk) and common table salt as well as intercropping suitable crops under young coconuts is a profitable package of technologies capable of improving and sustaining coconut farm productivity in the Philippines.

Soybean is a food security crop in Benin due to its high nutritional value but its yield in the farmers’ cropping system is very low. The present study aims to provide appropriate response to the yield variability among fields in two agro-ecological zones of Benin namely: Southern Borgou zone (AEZ 3 in the north) and cotton zone of central Benin (AEZ 5). Soil samples were collected from 0-20 cm depth in 120 fields (50 in the AEZ 3 and 70 in the AEZ 5). pH (water), soil organic carbon (Walkley and Black method), total nitrogen (Kjeldahl method), CEC (0.01 N ammonium acetate at pH 7 method) and available phosphorus (Bray 1) were determined in the laboratory of Soil Science Water and Environment (LSSEE) of the National Agricultural Research Institute of Benin (INRAB). Cropping system (crop rotations, soil fertility management practices) were also collected using an open ended questionnaire. Classification and regression trees (CARTs) models were used for data analyses. Soybean yield variability among the agro-ecological zones were registered and the highest yield recorded was less than 1 t.ha-1. Considering soil characteristics, soil organic matter level was the most important variable determining yield variability. Furthermore, quantities of P applied and farmyard manure were cropping practices inducing yield variability (86.4% and 15% of the variability respectively). Our results also show that, yield differences noticed among the agro-ecological zones were induced by CEC and pH (water). The study suggested promotion of integrated soil fertility management practices to sustain soybean yield in the study area.
