Abstract

The utilization of acid mineral soil often faces the problem of Al toxicity and low available P. The efforts to improve root function and neutralize the effect of high available Al are becoming important for increasing the growth of legumes, particularly as the cover crops at the plantation on acid soil. This research was aimed to find the effect of VA mycorrhyza inoculation, rhizobium, and humic acid on the growth and nutrient content of four different legume species. It was a three factor factorial experiment arranged in a completely randomized design with three replications. The first factor was four legume species: Calopogonium mucunoides, CaloPogonium ceurelieum, Centrosema pubescens and Puerari  iavanica the second factor was four different inoculants: none (M0), MVA (M1), rhizobium (Mz), MVA + rhizobium (M3); the third factor was two rates of humic acid application: without (Ho) and with humic acid (H1) The results proved the positive effect of those three factors on the growth of shoot and roots. The responses of root growth on microorganism inoculations and humic acid were different among the legume cover crop species. The role of humic acid was significantly better if there was a synergism between MV A and rhizobium. Key words: Mycorrhyza, Rhizobium, Humic acid, Legume cover crop

Abstract

The effect of bagase compost application on nutrient uptake and growth of sugarcane was studied at PG Jatitujuh. Majalengka, West Java, from October 1998 to March 1999. The experiment was arranged in split plot design with three replications. The bagase compost as sub plot and the recommended rate of inorganic fertilizer as the main plot. The rates of bagase compost were 0.0, 2.5, 5.0, and 7.5 ton/ha and the recommended rate of inorganic fertilizers were 100%, 75%, and 50% of recommended rate. The recommended rate of inorganic fertilizer was 300 kg Urea, 200 kg ZA, 150 kg SP-36, and 200 kg KCl/ha. The results showed that bagase compost application at 7.5 ton/ha significantly increased nitrogen uptake at 3 Month After Planting (MAP) compared to no compost, but did not affect P2O5, K2O and  S. Lower rate of inorganic fertilizer decreased S uptake at 2 MAA, but did not affect N, P2O5 dan K2O. Combination of 5.0 ton/ha compost bagase with 100% recommended rate of inorganic fertilizer tended to increase sugarcane growth. Bagase compost application with inorganic fertilizer did not affect the percentage of growth, height, and diameter off  stalk.   Key words: Sugarcane, Bagase compost, Nutrient uptake

Abstract

Utilization of coastal plain area for farming are scarce due to the problems faced in the development of those lands such as low fertility, high percolation as well as evaporation rate. Temperature ranges from 40-60°C. In order to increase the utilization of the land, an attempt was done to study the effects of number of manure and irrigation rate on  the yields and soil water extraction of maize, groundnut, tomato and chilly pepper in sandy soil. A series of experiment was conducted from April to December 200I using completely randomized design. The treatments included 4 rates of manure i.e. 10, 15,20 and 25 MT/ha and 4 rates of irrigation I.e. 0.6 I/day, 0.9 I/day, 1.21/day and 1.5 I/day. The result of the experiment showed that the favourable condition to keep moisture content in sandy soil at field capacity and flushing of heat in the soil was achieved at irrigation rate of 1.2 I/day except for tomato which obtained the highest water extraction at irrigation rate of 0.9 I/day. Soil water extraction decreased between 0.15 to 0.55% when irrigation rate were reduced from 1.2 I/day to 0.9 I/day and 0.6 I/day on: maize, groundnut and chilly pepper. The highest yield was obtained at fertilization rate of 20 MT/ha except for maize which obtained the highest yield at fertilization rate of I0  MT/ha.
