Effect of Spraying Mineral Fertilizer and Sorbitol Sugar on Growth and Yield of Capsicum frutescens L.

Abstract

This experiment was carried out in order to study the effect of Mineral fertilizer and Sorbitol Sugar on the growth, and yield produced by chili pepper plant Barbarian F1, A factorial experiment with two factors, Mineral Fertilizer concentration 0, 0.5, 1, 1.25 and 1.5 g L^-1 and Sorbitol Sugar 0 and 10 g L^-1 was used in the term of (RCBD) with three replications. The results showed significant superiority of Mineral Fertilizer at 1.5 ml^-1  in the plant height (59.62 cm plant^-1 ), number of main branches plant^-1 (5.600 branch plant^-1), total leaf area (21.100 dm² plant^-1), number of fruits plant (88.25 fruit plant^-1). One plant yield (0.718 kg plant^-1) and total yield (23.94 tons hectare^-1).  The result also showed a significant increase of Sorbitol sugar in concentration 10 g L^-1 in the plant height, number of branches¹, total leaf area by balance, number of fruits, (58.63cm, 5.493 branch plants^-1, 21.98dm², 84.78 fruit plant^-1, 0.685 kg plant^-1, and 23.03 ton hectare^-1 respectively). The interaction indicated that both variables were significant for all the studied traits, indicated that the response of pepper to the first variable is related to the second one. Thus, the research has concluded that the Interaction of variables, mineral fertilizer (1.5 g L^-1) and Sorbitol Sugar 10 g l^-1 has a great combination to increase the growth and the yield of chili pepper.
