Abstract

Volcanic ash actually need  agent like an organic matter to mineralized. The study aims is to determine the effect of volcanic ash of Kelud and manure on the availability of calcium in Alfisols, the absorbent of calsium and their status for peanuts growth.This is greenhouse experiment arranged in factorial completely randomized design with single treatment. The result have been analyzed with analysis of variance by F test at 5% and the average comparison test using DMRT at 5% than will continued with Pearson Corelation test for analyzing the relation of intervariable. The results showed that volcanic ash of Kelud eruption and manure treatment significantly on leaves, chlorophyll, nodules, weight of wet crop stover, pH, CEC, Ca-total and Ca plant tissue but no significant on height of peanuts, stover dry weight, exchangable Ca and Ca uptake.Volcanic ash of Kelud and manure are better used as ameliorant than as a planting media.

Abstract

Mung beans are one of the common beans comodities consumed after soybeans and peanuts. The national mung beans production was 0.7 tons in average, which is lower than the potential yield. Production of mung bean can be improved by modifying the microclimate by mulching and regulating crop density. The purpose of this research was to improve the yield of mungbean. Research method used was Completely Randomized Design (CRD). The treatments were organic mulching of mahagony leaves, straws, husks, and without mulch (M1, M2, M3, M0) and the crops density 1 and 2 crops (B1 and B2). The results showed interaction between organic mulches and crops density significantly affected the crops’ height and number of productive branches. Interaction of straw mulches and two crops density increased the crops’ height 37,91% than the control and has the most productive branches. Organic mulches significantly affected to flowering period and number of hardseeds. Husk mulches accelerated flowering period and decrease the number of hardseeds. Organic mulch and number of crop’s density treatments has not to improve the yield of mungbean yet. The yield of mungbean can achieved in this research was 1,54 ton ha-1.

Abstract

Arrowroot  able  to  be  alternative  food  because  it  has  high  enough  carbohydrate  content.  The  increase  of productivity of arrowroot can be reached by using plant spacing and fertilization. This study aims to determine the effect of plant spacing and fertilization, also their interaction on growth and yield of arrowroot (Maranta arundinacea L.). This research was held from March to November 2016 in the experimental land, Faculty of Agriculture, Sebelas Maret University. This research arranged in Completely Randomized Block Design (CRBD) consisted of 2 factors; dosage of N,P,K fertilizer (with 3 levels) and plant spacing (with 2 levels). Each treatment was repeated 4 times. The data obtained analyzed with analysis of variance and followed with Duncan Multiple Range Test at 5% level if any significant influences. The results showed that the interaction between plant spacing of 30x40 cm and urea, Sp36 and KCl 300Kg-1ha significantly increased the number of tillers and diameter of arrowroot respectively. The use of plant spacing 30x40 cm tends to increase growth and better yield. The use of 300 Kg-1ha Urea, SP36 and KCl fertilizer significantly increased plant height, while 150  Kg/ha urea,  SP36 and  KCl fertilizer significantly increased the number of tuber crops.
