Abstract

This study examines the effects of climate on the growth and yield of groundnut in Yola Adamawa State, Nigeria. The experiment was conducted during the 2013 cropping season at the Research and Demonstration Farm of the Department of Crop Production and Horticulture, Modibbo Adama University of Technology Yola. The treatment consists of three groundnut cultivars namely, Kampala, Gargajiya and Kwachamba. The experiment was laid out in Randomized Complete Block Design (RCBD) replicated three times. The climatic variables used in this study include; rainfall, maximum temperature, minimum temperature, soil temperature, sunshine and relative humidity. Agronomic parameters measured were plant height per plant, number of branches per plant, number of leaves per plant, leaf area per plant, grain yield per plant and grain yield per hectare. Correlation analysis was used to examine the relationship between climatic elements and the growth and yield of groundnut. The result of the correlation analysis shows that, relative humidity correlates positively with all the growth parameters (vegetative growth) at 1% significant level, rainfall also correlates positively with leaf length, leaf area at 1% and leaf height at 5% significant level. While temperature correlates negatively with the vegetative growth at 1% significant level. Rainfall, maximum temperature and soil temperature correlates positively with yield at flowering and pegging stages at 1% significant level. Also rainfall correlates positively with yield at vegetative growth, pod development and pod filling stages at 5% significant level. Minimum temperature correlates positively with yield at pegging stage at 1% significant level, but correlates negatively with vegetative growth and podfilling at 5% significant level respectively. Sunshine correlates negatively with yield at pegging stage at 1% significant level. Relative humidity has positive correlation with yield at vegetative growth stage and negative correlation with flowering, pegging and pod development stages at 1% significant level. Seminars and workshop should be organized to give more orientation to farmers on the effects of climate on the growth and yield of groundnut. The planting of groundnut should commence as soon as antecedent moisture status of soil is good for effective germination.
