RESPONSE OF TOMATO (LYCOPERSICON ESCULENTUM) AND OKRA (ABELMOSCHUS ESCULENTUS (L.) MOENCH) TO RATES OF NPK NUTRIENTS APPLIED AS MINERAL, POULTRY MANURE AND OIL PALM RESIDUE IN THE GUINEA SAVANNA AGRO-ECOLOGICAL ZONE IN NIGERIA

Abstract: Experiment was conducted at the Kogi State University Research and Demonstration Farm (latitude 70 301 and longitude 70 091E), Anyigba in the Southern Guinea savanna agro ecological zone of Nigeria. The study evaluated the effect of different nutrient sources (inorganic (MF), poultry manure (PM), oil palm residue (OPR), MF + PM, MF + OPR), and rates on the growth and yield of tomato and okra in the Guinea savanna agro-ecological zone in Nigeria. The aim of the research was to apply three rates of N: 0, 150 and 300 kg N ha-1 using inorganic, organic sources or their combination. Integrated nutrient applications performed better than individual application for all the nutrient sources, with the best performance obtained in MF + PM combinations. With integrated application of N at the rate of 150 kg PM ha-1 + 150 kg MF ha-1 being recommended for higher tomato and okra yield.
