Increasing the Production of Soybean (Glycine Max L.) By Using Mulch of Rice Straw and Appliying Poc (Liquid Organic Fertilizer) From Seaweed (Gracilaria Sp.) and Cattle’s Urine

Abstract

Soybean is the crops that are important in the food and feed industry. It acts as a source of vegetable protein thatis very important in improving people's nutrition because it is safe for health and cheaper. This study aimed to assess the effect of combined treatment of liquid organic fertilizer from waste of seaweed and urine of cattle and supplementing rice straw mulch with different dose to the growth and production of soybean of Wili variety. This study was conducted in November 2014 until March 2015 in the Dusun Kajuara, Awangcenrana Village, District Cenrana, Bone regency. This study was prepared by using the Separated Plots Draft (RPT). The main plot is the use of rice straw mulch with four treatments, ie: without the straw, straw mulch 2 tons / ha, straw mulch 4 ton / ha, and straw mulch 6 tonnes / ha. The subplots were fertilization with four treatments, ie: without POC, Seaweed POC, cow urine POC, and the combination of seaweed POC and cow urine POC. The results showed that the combination of supplementing rice straw mulch and POC from waste seaweed and cow urine occured real interaction to the weight of berangkasan, number of empty pods, soy production per plot, productionton.ha-1. The combination of supplementing rice straw mulch and POC from waste seaweed and cow urine showed the best response because it is capable of producing (2.6 ton / ha) is higher than the potential ability of the results (1.6 ton.ha).
