The Effect of Vermicompost and Other Fertilizers on the Growth and Productivity of Pepper Plants in Guyana

Abstract

Present research was carried out during the year 2014–2015 at the National Agricultural Research and Extension Institute (NAREI) to determine the effect of vermicompost and other fertilizers on the growth and productivity of pepper plants (Capsicum chinense). Plants were treated with five different treatments, namely T1 (Promix), T2 (vermicom-post), T3 (189), T4 (189 + vermicompost), and lastly, control which had no fertilizers. T1, T3, and T4 were inorganic fertilizers, and T2 was organic. Results obtained showed that T3 (chemical fertilizer) has a significanteffect on the growth of pepper plants producing plants with better plant height, number of leaves, number of branches, stem diameter, higher fruit yield, fruit weight and fruit diameter. Plants treated with this treatment also had higher fruit yield, fruit weight, and fruit diameter. Mineral nutrients were highest in plants treated with inorganic fertilizers as compared to the organic fertilizer. Maximum chlorophyll level was present in plants treated with T2. There were relatively high levels of pest and diseases in plants treated with chemical fertilizers, delayed flowering and fruiting period and high levels of leaf and fruit abscission as compared to plants treated with organic fertilizer (T2). Moreover, T3 has proven to have a greater effect on the growth parameters of pepper plants but not the quality of plants produce
