GROWTH AND NODULATION OF GROUNDNUT FERTILIZED WITH INORGANIC N AND P ON DIFFERENT PEDONS IN MINNA, NIGERIA

Abstract

Growth and nodulation of groundnut fertilized with inorganic N and P was evaluated on different pedons of the Teaching and Research Farm of the School of Agriculture and agricultural Technology, Gidan Kwano Campus, Minna in the month of March, 2013. There are 4 treatments as follows: control, 25 kg N ha-1, 60 kg P ha-1 and 25 kg N ha-1 + 60 kg P ha-1. There were also locations as pedon one, pedon two, pedon three and pedon four. The pot experiment was arranged in a complete Randomized Design (CRD) replicated 3 times. Results revealed that the effect due to the interaction between fertilizer and location was not significant. However, location significantly affected plant height, nodule number and nodule weight. Fertilizer only affected leaf number. Planting groundnut (SAMNUT 22) in pedon 3 support good growth and nodulation.
