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

Hydroponics is one of the urban farming techniques that can be used to improve crop yield. Nowadays, the supply of all nutriens in hydroponics, particulary phosphate only derived from inorganic fertilizers. Application of arbuscular mycorhiza fungi (AMF) as bioagent may help plants to fill its nutrient need, especially phosphate. This study aimed to find out the best concentration of phosphate fertilizer to be applied to the hydroponic Ebb-flow system model. The stage was to test several vegetable plants with various concentrations of phosphorus (0, 20, 40, 80 ppm) on the Ebb-flow hydroponic system. Vegetables used were romaine lettuce, red lettuce, and kale. Interaction was found between vegetables and the variety of phosphate concentrations and the root colonization by AMF, and phosphate uptake. The AMF applications on the hydroponic Ebb-Flow system model reduced phosphate fertilizer need by 40 ppm (50%), on red lettuce 0 ppm (100%), and on kale 20 ppm (25%). Besides lowered phosphate doses, such applications also increased the plant yield.
