Abstract
This research aimed to analyze the effect of fertilization of N, P and application of green manure of crotalaria to increase yield of maize plant in marginal dry land. The experiment was carried out at the dry land of South Sulawesi Province, Indonesia from June to September 2013. This research was designed by using Split Plot Design. The main plot used green manures which consisted of two levels, i.e: without green manure and application of crotalaria green manure. The subplot was fertilization of N and P which consisted of three levels, without of fertilizer N and P; fertilization with a dose of 67.5 kg N.ha-1 + 33 kg P2O5.ha-1; 135 kg N ha-1 + 66 kg P2O5 ha-1. The results showed that fertilization of N, P and application of crotalaria green manure improved growth and increase the yield of maize. Fertilization with a dose of 135 kg N ha-1 + 66 kg P2O5 ha-1 with the application of Crotalaria obtained yield of maize as many as 7.234 tons ha-1 while fertilization at the same dose without the application of crotalaria obtained the yield as many as 6.172 tons ha-1.
本研究旨在分析在边缘旱地施氮、施磷和施用绿肥对玉米增产的影响。实验于2013年6月至9月在印度尼西亚南苏拉威西省的旱地进行。本研究采用分块法设计。主地块采用绿肥,分为不施用绿肥和施用绿肥两个层次。子图为氮磷肥,分3个水平,不施氮磷肥;67.5 kg N.ha-1 + 33 kg P2O5.ha-1施肥;135 kg N ha-1 + 66 kg P2O5 ha-1。结果表明,施氮、施磷和绿肥能促进玉米生长,提高产量。施肥135 kg N / hm -1 + 66 kg P2O5 / hm -1并施用红豆草的玉米产量可达7.234吨/ hm -1,而相同剂量不施用红豆草的玉米产量可达6.172吨/ hm -1。
