Effect of Chemical Fertilizer Management in Combination with Boron on Growth and Yield of First Ratoon Cane Planted in Kamphaeng Saen Soil Series

Abstract

This study investigated the effects of chemical fertilizer management in combination with boron on growth and yield of first ratoon cane var. LK 92-11 planted in Kamphaeng Saen soil series. Experimental design was arranged in Randomized Complete Block (RCBD) with three replications and consisting of nine treatments. The study revealed that the application of 110% of chemical fertilizer based on soil chemical analysis in combination with 156 g/rai of B gave the highest plant height, number of stalks for one-meter row, leaf greenness, fresh yields, weight/stalk, number of internode/stalk, CCS, sugar yields and concentrations of N, P, K in stalks. This was not different from the application of 110% of chemical fertilizer with 104 g/rai of B. Furthermore, the application of 110% of chemical fertilizer with 156 g/rai of B gave the highest concentration of B in the stalks, followed by that the application of chemical fertilizer based on soil chemical analysis in combination with 156 g/rai of B, the application of 110% of chemical fertilizer with 104 g/rai of B and the application of chemical fertilizer based on soil chemical analysis in combination with 104 g/rai of B, respectively
