Abstract

The practice of environmentally friendly shallot cultivation is nowadays widely applied by farmers, beside reducing environmental contamination and producing agricultural products that are safe for consumption, it can also increase shallot production. This study aimed to determine the effect of biochar, compost, and organic pesticides on the growth and yield of shallot, and the activity of microorganisms in the soil. The study was conducted in Klampok Village, Wanasari, Brebes Regency from January to July 2020 using a complete randomized block design with nine treatments which were a combination of biochar, compost, organic pesticides, recommended dose of pesticides, and farmers’ dose of pesticides. The shallot seed used was the Bima Brebes variety. Soil characteristics, compost nutrient contents, plant growth, shallot yield, and total soil bacteria population were measured. The study showed that the yield of shallot was 16.7 tons/ha obtained from adding compost and recommended doses of pesticides. The treatment of biochar, compost, and organic pesticides, although it has not been able to increase the growth and yield of shallot, it can be applied for shallot cultivation as it can increase the total bacterial population of soil, reduce the use of chemical pesticides, reduce production input costs, and environmentally friendly.

Abstract

The quality of pond bottom soils is an important factor in fish cultures. The aims of this research were to find out the best composition natural feed to grow in Inceptisols pond bottom soil by marling it with Ultisols. There were 3 treatment combinations of I-U. The proportions are 70%:30%, 50%:50%, 30%:70% and a control (100%:0%). Each treatment was replicated 3 times. These mixtured soils were spread out at the bottom of 12 individual ponds (1 x 2 x 1 meter3), in 15 cm thickness. The soil physical, chemical and biological characteristic changes of the pond bottom were observed and analyzed. The study found that the physical fertility improvement through of marling Inceptisols pond bottom resulted in change of soil textures from sandy loam to clay loam and from sandy loam to clay. The chemical characteristic results showed that the ranges of ratio C/N was 4.31-6.81, Fe available was 6.39-17.76 ppm, K available was 60.14-68.25 ppm and CEC was 15.96-27.87 cmol(+)kg-1, respectively. The best treatment combinations was I-U that produced 46% clay content, which result in the highest abundanceof benthic algae and plankton production.
