Abstract

This study was conducted to determine the effect of different levels of NPK 15:15:15 on three cultivars of groundnut (Kampala, Honey, Nwanyiocha). Levels of NPK 15:15:15 include 0kg, 0kg, 20kg and 30kg/ha were assigned to these three cultivars of groundnut. Parameters measured were number of leaves, number of branches, plant height, days to 50% flowering, Number of pods/plant, Pod weight, 100-seed weight, and Yield (t/ha). These data were then be subjected to analysis of variance (ANOVA) using GENSTAT release 10.3 statistical software. Results showed significance differences (P<0.05) amongst treatments in some parameters measured. Nwanyiocha at10kg/ha of NKP 15: 15: 15 produced the best growth and yield indices while kampala cultivar had the lowest growth indices. In the number of branches all cultivars had significant growth without the application of fertilizer. Honey cultivar had a favourable growth from 4 WAP to 8WAP unlike the kampalacultivar. I0kg of NPK 15:15:15 had the best effect on the three cultivars ofgroundnut compared to other levels ofNPK 15:15:15 that were applied. It is concluded that NPK 15: 15: 15 had significant effect on groundnut growth. The best cultivar with regard to yield was Nwanyiocha (1.6t/ha) and was therefore recommended for farmer in the research area with the fertilizer application of NPK 15:15:15 at 20kg per hectare.
