Abstract
The study was conducted to investigate the effect of Black Plastic Mulch (BPM) and different rates of NPK (15:15:15) fertilizer on the growth and yield of three chili cultivars under field and protected cultivation. Two levels of mulch (BPM and no mulch), three levels of NPK (0, 200 and 300 kg/ha), and three cultivars “Demond F1” (DF1), “Legon 18” (L18), and “Shito Adope”, (SA) were used. Split application of half of each of the 200 and 300 kg/ha rates were applied two and four weeks after transplanting. Vegetative growth indices, soil moisture, and soil temperature were measured at 2, 4, 6, 8, and 10 weeks after transplanting. The yield was calculated using AVRDC (1990) formula for chili pepper. The study revealed an increase in soil temperature and moisture under BPM for both studies. Also, 200 kg/ha NPK and BPM led to an increase in vegetative growth and yield for DF1 and SA. However, 300 kg/ha NPK decreased vegetative growth. In addition, there was no significant influence of BPM on the number of fruits harvested. However, for the pot study, BPM led to an increase in the number of fruits for “Legon 18” as compared to the other cultivars. The study, therefore, concludes that 200 kg/ha NPK was the best when cultivating DF1 and SA, for chili growth and development in the savannah ecological zone.
