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.

Abstract

TITLE : CHANGES OF P SORPTION ON ULTISOL DUE TO ADDITION OF COAL FLY ASH-CHICKEN MANURE MIXTURE. High soil P sorption which result in low P availability for plants is one of important constraints in Ultisols. The objective of current research was to study the effect of coal fly ash-chicken manure mixture (FA-CM) on the changes in P sorption and availability in Ultisols. Two treatments - FA-CM mixture (w/w of 1:1) at the rate of 0, 15, 30, 45 and 60 ton ha-1, and P fertilization at the rate of 0, 87, 174, 261 and 348 kg P2O5 ha-1 - were tested. These treatments were arranged according to Factorial Completely Random Design with three replicates. Results of current research showed that FA-CM and P rates and their interaction significantly affected the values of point of zero charge (PZC), pH and soil negative charges. FA-CM mixture as a soil ameliorant decreased P sorption but it increased available P in Ultisols by increasing both soil pH and negative charges. The application of FA-CM at 30 tons ha-1 and P at 174 kg P2O5 ha-1 resulted in better increases in soil charges than any other combinations. However, the lowest P sorption (127.07 mg kg-1) and the highest available P (102.21 mg kg-1) was resulted in by the applications of 42.64 tons of FA-CM ha-1 and 261 kg P2O5 ha-1.

Abstract

Title : EFFECT OF LITTER QUALITY  AND DOSAGE TO  POTENTIAL NITRIFICATION IN SOIL AND YIELD OF SWEET CORN. Nitrification is conversion of NH4+ to NO2¬- and NO3- by specialized bacteria. The process is very harmful to the plant, therefore should be controlling nitrification in the soil with the application of litter. The purpose of this study is to know the effective of litter quality and dose to control potential nitrification in the soil, and optimum for sweet corn cultivation. This research used a Randomized Block Design (RAKL) with two factor, the first is quality of litter (teak, kirinyu and a combination (teak and kirinyu) and second is the dose (5 Mg / ha, 12.5 Mg / ha and 20 Mg / ha). The results showed that the interaction of quality and dose significantly affect to soil nitrification potential at 2nd and 10th week. Application of kirinyu litter with high quality and doses of 20 Mg / ha had the highest concentration of NO2-, while the application of mix litter with middle quality and dose of 12.5 Mg / ha were lowest concentration of NO2-. Nitrification potential was not significantly correlated with crop yields. Litter kirinyu with high quality and dose of 20 Mg / ha is expected optimum to be applied in the cultivation of sweet corn.

Abstract

TITLE : VERTISOLS N-MINERAL DYNAMICS IN SEVERAL LITTER QUALITY COMBINATION AND N-SWEET MAIZE UPTAKE. Problems are often found on farms in humid tropics that lack of balancing between number and availability of nutrients. The imbalance will lead to nutrients leaching, especially NO3- to the bottom layer. NO3- is the result of oxidation of NH4+ through a process called nitrification, hence it is important to control over the process as it. The purpose of this study was to determine the effect of litter quality Trimmings (based on the content of polyphenols and lignin) to the dynamics of N-NH4+ and N-NO3- land. This study is a field experimental with basic use Completely Group Randomized Design. The first factor is addition of Chromolaena odorata litter which represent high quality (lignin content 4.27 %, 17.12 % polyphenols), Tectona grandis litter representing low quality (lignin content of 14.54, 11.92 % polyphenols), and litter mixtures (Chromolaena odorata+Tectona grandis). The second factor dose of 5 Mg/ha, 12.5 Mg/ha, 20 Mg/ha. Analysis of the data using the F test, if the results of analysis of variance is significant, it forward to Duncan Test at α level = 0.05.
