Abstract
Sugarcane stalk population is a key determinant of cane yield and knowing the right intra-row spacing is a critical factor in sugarcane production for a given environment. Therefore, a field experiment was conducted at Omo Kuraz Sugar Estate during the 2018/ 2019 cropping season to determine the effect of intra-row spacings (5 cm overlapping, end-to-end, 5 cm spacing between setts and 10 cm spacing between setts) on growth, yield, yield components and quality parameters of sugarcane varieties (N14, Mex54/245 and C86/112). The treatments were arranged in a split-plot design with three replications. Varieties were represented as the main plot whereas setts spacing treatments were assigned to sub-plots. Analysis of variance revealed that the intra-row spacing effect didn’t show a significant difference in the number of tillers, plant population, millable cane, cane yield, sugar yield, and Brix percent whereas significant (P<0.05) differences were observed in stalk height, stalk girth, number of internodes and weight per stalk. Therefore, the 10 cm intra-row spacing of three budded setts can be recommended for better productivity and profitability of N14 and Mex54/245 varieties at the Omo Kuraz Sugar factory.
Highlights
The Inner Niger Delta or DIN has been recognized as a Ramsar site since February 1, 2004
The specialized services of the State intensify the chemical treatment during the return of the evening when the birds have a great flight activity and are eager to group in their dormitories or nesting areas or in the morning of happiness when they leave
For foraging the bird's contact with the drops may be by sedimentation or by impact
Summary
The Inner Niger Delta or DIN has been recognized as a Ramsar site since February 1, 2004. It is so important for people practicing agriculture, fishing, and breeding as well as the animals that live there because of the diversity and the richness of its ecosystem. The primary sector (agriculture, livestock, fishing) is the primary source of economic growth and employs over 80% of the population. Some of which are residents, and others seasonal or migratory, have habitats very suitable for their feeding and reproduction. 1963 presented an inventory of DIN avifauna composed of several species including residents and migrants. The granivores present in the area constitute real dangers for cereal crops. The peasants tirelessly engage in the means of struggle against them
