Soil Management and Crop Yield

This work aimed to evaluate the industrial characteristics and the yield of sugar cane under the influence of different blades of irrigation with and without effect of fertirrigation with N and K. The plant material was obtained by manual cutting, from a cultivated area with the variety RB 85-5453, Federal Institute Goiano - Campus Rio Verde - GO. The experimental design used randomized blocks, a fully randomized 5 x 2 factorial design was used, with four repetitions The treatments consisted of five levels of hydration (100, 75, 50, 25 and 0% of soil moisture at field capacity) combined with and without application of N and K way irrigation water (fertirrigation). For determination of the parameters industrial of sugar cane were collected 10 stalks of each repetition, harvested 385 days of plant development. The following technological parameters more used were analyzed to estimate the quality raw material. There were increased the yield of sugar and alcohol of 34,48% and 12, 43% in blade of 75% fertirrigated, when compared to smaller increment occurred in 0% and the highest yield occurred under the blade of 75% only irrigated.
