Abstract

One of the efforts to increase crop yield based in sustainable agriculture is through the utilization of microbial inoculants (biofertilizers) and soil conditioners. Biofertilizer is an ingredient that contains beneficial microbial inoculants to increase soil nutrient availability for plants. Biochar has been recognized as a soil conditioner by improving soil physical, chemical, and biological properties as well as in retaining nutrients, thereby enhancing plant growth. However, the research regarding the effect of the combination between biofertilizers and biochar on growth and yield of upland rice are still at scarce. The field experiment was conducted to determine the impact of biofertilizers and biochar on growth and yield of upland rice in Andisols at Pasir Talang village in Rancakalong district, Sumedang, West Java.  This experiment used a Randomized Block Design (RBD) consisted of six treatments and four replicates. Biofertilizers consisted of N-fixer bacteria (Azotobacter chroococum, Azospirillum sp.) and phosphate-solubilizer microbes (Pseudomonas mallei, P. cepaceae, Aspergillus niger and Penicillium sp.). The treatments were combination of biochar (2,4, and 6 t ha-1) and biofertlizers (0 and 50 kg ha-1). The result of experiment revealed that combination of biochar and biofertilizers increased the growth and yield of upland rice significantly. The application 4 t ha-1of biochar and 50 kg ha-1 of biofertilizers gave the best yield of 5,81 t ha-1.

Abstract

Marginal soils have problems of low availability of nutrients, especially phosphorus. Phosphate solubilizing microbes can produce organic acid that dissolve P in the soil. Futhermore, the PSM also produce extracellular enzymes asa phosphatase that catalyze mineralization of organic P become inorganic P. Phosphate solubilizing bacteria (Pseudomonas mallei and Pseudomonas cepacea) and phosphate solubilizing fungi (Penicillium sp. and Aspergillus sp) is selected based on the ability of dissolving P and the production of growth regulators. Research at this stage aims to determine the biological fertilizer application techniques (PSB and PSF) as well as different types of P fertilizers to improve soil P available, growth and yield of maize. Field experiment on Ultisol Jatinangor implemented using a randomized block design (RBD) to test how applications PSM plus (giving 1, 2 and 3 applications) as well as the type of fertilizer P (SP-36 and rock phosphate). The results showed that the application of PSM can improve soil P-available growth and yield of maize. Application of PSM biological fertilizer could reduce the need for fertilizer P by 50%. PSM application once the application (early planting) with SP-36 dose 50% can increase content of soil P (P-available), and yield of maize on Ultisols.Keywords : maize, phosphate solubilizing microbes, Ultisols
