Hassan, Siti Aishah and R., Zainal Abidin and M. F., Ramlan (1995) Growth and Yield of Chilli (Capsicum annuum L.) in Response to Mulching and Potassium Fertilization. Pertanika Journal of Tropical Agricultural Science, 18 (2). pp. 113-117. ISSN 0126-6128
A field experiment was canducted 10 study the influence of levels of potassium fertilizer (0, 66 and 132 kg ha-1) and types of mulching (black plastic, reflective plastic and coconut fronds) on growth and yield of chilli. Plant height, yield, fruit number and dry weight of plant increased with increasing K levels and mulching. Yields were increased by 89% and 142% with K levels of 66 and 132 kg ha-1, respectively. Highest yield was obtained from plant grown under reflective plastic mulch. Nitrogen, P, K and Ca content in leaf tissues, soil temperature and moisture under mulched conditions were higher than without mulch. There was a positive correlation between plant dry weight with soil temperature and moisture.
