Abstract

The effects of some soil properties on yield, yield components and qualities of millable cane were analyzed using classical stepwise regression methodologies. The aim of the study was to determine the soil variability, which was effected yields and qualities of the millable cane. By this, 140 grid sample units of 20 x 20 square meters were allocated in the sugarcane field on Kamphaeng-Sean soil series. In each grid unit, there was 15 rows of 1.33 meters apart. Duck manure and 16-20-0 chemical fertilizer were used as a basal fertilizer. Soil chemical analysis was determined by standard analytical methods. Yield and sugarcane quality such as CCS and fiber percentage was collected in each individual grid. Stepwise regression analysis show significant affects from total soil nitrogen and exchangeable potassium to sugarcane yield and CCS respectively. Semivariogram of yield (millable cane), number of cane and cane weight give a guideline for precision agriculture or site-specific nutrient management approach.
