Abstract

Effect of Azolla Based - Organic Fertilizer, Rock Phosphate and Rice Hull Ash on Rice Yield and Chemical Properties of Alfisols. The application of chemical fertilizer for long time may adverse soil environment. Organic agriculture, for example combination use of azolla based-organic fertilizer, phosphate rock and rice hull ash,  was one of ways that able to recover it.   Research was conducted in Sukosari, Jumantono, Karanganyar while soi chemical properties analysis was analysed in Soil Chemistry and Fertility Laboratory, Fac. of Agriculture, Sebelas Maret University April to November 2013. Research design used was RAKL with 5 treatments, each repeated 5 times. The treatments applied were P0 (control), P1 ( azola inoculum dosage 250 g/m2 + phosphate rock + rice hull ash equal to 150 kg/ha KCl), P2 (azola inoculum dosage 500 g/m2 + phosphate rock equal to 150kg/ha, SP-36 + rice hull ash equal to 100 kg/ha KCl), P3 (manure dosage of 5 ton/ha),P4 (Urea 250 kg/ha + SP-36 150 kg/ha + KCl 100 kg/ha). Data analysed statistically  by F test (Fisher test) with level of confident 95% followed by DMRT (Duncan Multiple Range Test) if any significant differences. The result showed that the treatment combination of azolla, phosphate rock and rice hull ash increase soil organic matter content, cation exchange capacity, available-P and exchangeable-K as well as rice yield ( (at harvest-dry grain weight and milled-dry grain weight).

Abstract

Title : The Effect of Azolla Compost and Organic Pottasium Fertilizer Dosages on Pottasium Availability and Yield of Peanut on Alfisol. Production of groundnut can not meet the national demand right now. One of the reason is the degradation in soil fertility, such as potassium deficiency and low of soil organic matter content. Plants that has potassium-deficiency can not utilize water and nutrients from the soil efficiently. In organic farming system, soil exchangeable-potassium and organic matter content can be increase by the application of plant ash as organic potassium and azolla compost. The research conducted to determine the proper dose of azolla compost and organic potassium to increase exchangeable-potassium and yield of groundnut on Alfisol soil at Jumantono, Karanganyar District, Central Java, Indonesia. The experiment was arranged in Completely Randomized Design (CRD) with single treatment factor of azolla compost and organic pottasium combination (P1, P2, P3, P4, P5, P6, P7, P8) as well as manure and NPK fertilizer treatments. The Variables using in this experiment are K exchanged, CEC, Organic Matter, Total N, pH, plant height, fresh weight and dry stover, fresh weight, dry and number of pods, weight and number of seeds. Data were analyzed by F test and DMRT at 5% level. The land use media as much as 5 kg per polybag with 3 number plants per poybag, and in the second week we used to thinning the plants. Everyday we also doing watering and weeding. The observation were made every week until phase of generatif The results showed the application of azolla compost and organic potassium can increase exchangeable-potassium and yield of groundnut in Alfisol soil. The highest exchangeable-pottasium (0.53me%) taken from the treatment of P7. Moreover the application of azolla compost and organic potassium increased CEC, soil organic matter content, total-N soil as well as shoot fresh and dry weight of peanut.

Abstract

Shallot is a high-economic value commodit, but so far the supply is still lower than the demand. One of the production problem is “moler” disease of shallot (MDS) caused by Fusarium oxysporum f.sp. cepae (FOCe). The aim of this research was to study the potentiality of shallot rhizobacteria (SRB) from various soil ordo to inhibit (MDS). This research was held in the Laboratory of Biology and Soil Health and Greenhouse at UNS. This research was carried out by exploring rhizobacteria of shallot planted on Entisols, Andisols, and Vertisols. Rhizobacteria exploration results were tested for their ability to control Fusarium oxysporum f.sp.cepae (FOCe). Inhibitory ability test of SRB to FOCe was carried out in vitro and on shallot in the greenhouse. The research cused a Completely Randomized Design (CDR) with two factors. The first factor was rhizobacteria combination and the second factor was various soil ordo (Andisols, Entisols, and Vertisols). Each treatment was repeated three times. It was obtained three rhizobacteria isolates from Vertisols (B15: 70%), Andisols (B12:45,55%), and Entisols (B10:46,67%) being the highest inhibition results to FOCe. The combination of rhizobacteria B12 and B10 provided the lowest intensity.
