The utilization of agricultural and livestock waste and the effect on new rice varieties yield on rainfed rice land of Ponjong - Gunungkidul

Abstract

It is believed that environmentally friendly management of agricultural land through the use of liquid and fermented organic microorganisms can preserve soil fertility, increase the soil microbial population, preserve the environment, as well as increase soil productivity. This research aims to determine the application of various local microorganisms (LMO) to the growth and yield of new rice varieties on the rainfed land of Ponjong-Gunungkidul. Furthermore, it was conducted from February to May 2017, and used a Randomized Completely Block Design (RCBD) with 3 replications and 6 different treatments, namely: M1 = Local Microorganisms of vegetable waste, M2=Local Microorganisms of fruit waste, M3= Local Microorganisms from banana weevils, M4= Local Microorganisms from urine and cow manure, M5 = Local Microorganisms from Gliricidia sp leaves, M6=A mixture of the five local microorganisms ingredients. The results showed that the application of organic fertilizers produced from agricultural and livestock waste and liquid microorganisms was able to increase the total number of the microbial population about seven times on M6 treatment compare to M1 treatment, while the Nitrogen fixation bacteria population and Phosphate solubilizing bacteria increased about six and three times, respectively on the soil rhizosphere. The harvested dry grain yield of the variety Inpari 33 (7.78 tons ha-1) showed a higher yield than that of Inpari Sidenuk and Inpari 19, namely 6.93 tons. ha-1 or 7.13 tons ha. The observation of growth and yield components revealed that the number of tillers, the number of filled grains per panicle, the weight of 1000 grains, and plant biomass showed a significant result and higher differences of Inpari 33 variety than the other 2 varieties used in this research by applying a mixture of five agricultural and livestock wastes ingredients (M6)

Growth and Production of Long Bean Plants (Vigna sinensis L.) on Concentration Level of Liquid Organic Fertilizer Banana Webs and Chitosan

“…P 233.84 ppm and K 2007.4 ppm [28,29,30,31,32,33]. Banana weevil liquid organic fertilizer has a role in the vegetative growth of plants and plants are tolerant to disease, high levels of phenolic acids help bind Al ions, Fe and Ca thus form the availability of Phosphorus (P) in the soil which is useful in the process of flowering and fruit formation [34,35,36]. Based on research that has been done on cucumber plants, giving a concentration of 90 ml/L gave the best effect on the parameters of plant height, number of fruit planted, fruit diameter, fruit length, and fruit weight [37,38,39].…”
