Determination of Placement Distance of Fertilizer for Sugarcane as an Agronomic Requirement Relevant in the Design of a Fertilizer Applicator

Abstract

Fertilizer placement distance at which sugarcane utilizes fertilizer optimally was determined in terms of its growth parameters (root distribution, stem height, stalk thickness, and leaf count). Three placement distances (4, 8 and 12 cm) were used as treatment and replicated four times. After subjecting the data obtained to Analysis of Variance (ANOVA) for Complete Randomized Design (CRD), the average means for a placement distance of 4 cm (for root distribution, stem height, stalk thickness and leaf count) are 3,910.75 cm 2 , 30.83 cm, 0.763 cm, and 9.5, while for 8 cm placement distance are 2,011.63 cm 2 , 27.70 cm, 0.699 cm, and 8.5. The values for 12 cm placement distance are 5,840.06 cm 2 , 34.55 cm, 0.788 cm and 11.25, respectively. These show that the effects of fertilizer placement distance on root distribution, stalk thickness and stem height are significant at 0.05 level of significance during three months of growth. It was highest at 12 cm placement and lowest was at 8 cm placement distance. Hence, fertilizer placement distance at 12 cm was recommended for the design and construction of a fertilizer applicator for sugarcane
