Effects of Split Application and Different Amounts of Area Fertilizer in Furrow Fertigation on Yield and some Quantitative and Qualitative Attributes of Sugarcane, Variety CP69-1062

Fertigation offers ease and efficient application of fertilizers, in contrast with the traditional application methods. In fertigation, the volume amount of fertilizer applied is about e94 al to the actual amount of nutrient need and, uptake by the plant. Nutrient leaching can be controlled by adjusting the fertilizer application rate in each and every fertigation event as based upon crop root depth. The aim followed in this study was to investigate the effects of split application of different rates of urea on yield and on some quantitative as well as qualitative attributes of furrow-irrigated sugarcane in a plantation 25 hectare of a newly planted farm belonging to the Dehkhoda Sugarcane Agro-Industry. A split plot experiment was conducted in the framework of a randomized complete block design of three replications. The main factor consisted of split application of fertilizer at three levels of: two, three and four splits. The sub-main factor was comprised of different amounts of fertilizer applied (350, 280 and 210 kg of urea corresponding to 100%, 80% and 60% fertilizer requirements, respectively). The results revealed that the two split treatment of with 60% fertilizer level was the mast preferred treatment in terms of all the quantitative and qualitative attributes and while two split treatment was the most acceptable treatment in terms of water use efficiency of sugarcane, extraction as white sugar of well as fertilizer use efficiency, with the figures of 7.474 and 0.710 kg/m3 and 437.7 kg/kg of urea, respectively. Moreover, the treatment of 60% fertilizer level performed better in terms of water use efficiency of sugarcane, white sugar and fertilizer use efficiency, amounting to 6.533 and 0.628 kg/m3 and 454.9 kg/kg of urea, respectively. The proposed methodology for optimum management of fertilizer application may result in a reduction of fertilizer use and nitrogen leaching from sugarcane agro-industry companies, farm soils. This would reduce groundwater pollution white increasing the community’s health.
