The Effect of Inorganic Fertilizer Residue Combined With Chicken Manure on the Yield of Relayed Solanaceous Crops

Abstract

The study was conducted at the farm of Leonard Q. Rosal, farmer cooperator in Pudoc Centro, San Vicente, Ilocos Sur from January to April 2007. It was aimed to put into practice the concept of relay cropping with the utilization of inorganic fertilizer residue combined with chicken manure and to compare the yield performance of relayed solanaceous crops. This study made use of the Randomized Block Design (RCBD) with three replications. They were laid out as follows: Treatment 0 - control (not applied with chicken manure, Treatment 1 - tomato (Lycopersicum esculentum) planted three weeks afer sowing and applied twice with chicken manure, Treatment 2 - sweet pepper (Capsicum anuum) planted three weeks after sowing applied with chicken manure, and Treatment 3 - eggplant (Solanum melongena) planted three weeks after sowing applied with chicken manure. Results showed that no significant difference on the yield of tomato although applied with chicken manure. This means that the soil nutrients were sufficiently supplied during the vegetative stage oftomato; thus, making the crop grew almost uniformly and developed fully. This was attributed to greater mumber and bigger fruits with a total of  419.5 kg of tomato produced. The yield of sweet pepper and eggplant gave significant differences. They were affected by the soil nutrient residues combined with chicken manure as a complete fertilizer which is essential for the growth and development. The varieties used, "aruy-uy sweet pepper" and "long violet eggplant" were found promising with total yield of 104.5 and 49.75 kg respectively. The plots applied with chicken manure also produced larger fruits and higher net income than Treatment 0 control (not applied with chicken manure.
