 Abstract

 

Nitrogen is the primary nutrient limiting sugarcane production throughout the world. A study was conducted in SONY sugar zone during the year 2015 on the effect of nitrogen fertilizer rates on the performance and yield of new sugarcane. The aim was to determine the optimal nitrogen rates for the new sugarcane cultivars. The treatments consisted of 11 cultivars KEN 98-367, KEN 98-530, KEN 98-533, KEN 98-551, KEN 00-13, KEN 00-3548, KEN 00-3811, EAK 73-335, KEN 82-121, KEN 82-601, KEN 82-493 and 3 levels of N fertilizer rates; 0 kg Nha-1, 80 kg Nha-1 and 160 kg Nha-1 as top-dress at five months after planting. The experiment was laid out as 11 x 3 factorial in a randomized complete block design (RCBD) having three replications with a gross plot size of 5 rows of 6 m long and spaced 1.2 m apart. Clean seedcane aged 10 months was used. The trial was harvested at 17 months after planting (MAP). Data was analyzed by ANOVA. The results showed that significant differences were noticed in girth, cane length, internodes number and cultivars. Nitrogen fertilizer rates and pol% cane did not differ between the treatments. KEN00-13 and EAK73-335 were at par (101.6 tch) and out yielded all the other cultivars, while KEN82-601 (93.4 tch) had the worst performance. Therefore, the study has established that there is a need for further evaluation on SONY sugar zone soil before appropriate nitrogen fertilizer rates are recommended, and the recommendation of cultivars for growers should be site specific.

Key words: Sugarcane, cultivar, nitrogen, pol% cane, fertilizer rates.
