Study in the appropriate dose of NPK fertilizer and organic fertilizer to sugarcane in Phung Hiep district, Hau Giang province
Hau Giang was the top province of sugarcane areas in Mekong Delta in 2008 - 2009 with approximately 15,573 ha, in which, Phung Hiep district was the focal production area of raw material sugarcane with 8,160 ha. To increase the economic efficiency of producers and contribute to the steady development in the raw material sugarcane areas, fertilizer test was conducted with QĐ13 variety at Hiep Hung commune, Phung Hiep district, Hau Giang province in 2010. The experiment was designed in block with nine fertilizer formulas and three replications in a completely random manner. The experimental results showed that using the N - P2O5 - K2O - organic fertilizer rate, which was 280-167-180-2,333 kg per ha, increased the cane plant’s growth and gave higher yield than that from farming habits
