Abstract

This study aimed to determine the density and diversity of spores of arboscularmycorrhizal fungi (AMF) inrhizosphereof five crops. The method used in this research was exploratory descriptive. The sites of soil samples taken were done purposively around the rizhospere of the plant selected.  Soil analysis and spore observations were conducted in the Laboratory of Soil Science and in the Laboratory of Agronomy of Faculty of Agriculture of Tadulako University, respectively. Higher number of spores was found in the rhizosphere of soybean and only a few numbers in cassava rhizosphere.  Low soil pH, P-total and C-organic tend to lower the number of spore living around the crop rhizosphere. The morphological characteristics of the spores found included sphere, ellipse, and oval, while the color comprised of brown, dark brown, transparent, yellow and brownish yellow.  The size of the arbuscular spores ranged from 63 – 250 mm. Keywords: Arboscularmycorrhizal fungi, crops, and rhizosphere.

Abstract

The aim of this research was to determine heat unit (degree days) of tomato grown in a greenhouse.  Heat unit was used to determine growing and development stage of tomato.  Tomato was planted in the greenhouse during August until December 2010 at the BALITKLIMAT, Cimanggu, Bogor.  The weather data such as air temperature, minimum and maximum temperature, and relative humidity were collected using authomatical weather station (aws). Solar radiation intensity was collected using solary meter. The results of the research showed that heat unit of tomato were 1661oC days. Average of air temperature in the greenhouse was 27.1oC and average of relative humidity was 74.2% with average radiation intensity was 9.3 MJ m-2 day-1

Abstract

The research of the objectives is know of boiling time sweet corn kernels on the physical, chemical and organoleptic properties of corn milk that quality to produce. The research were used a completely randomized design (CRD) with using boiling time sweet corn as a treatment that consisting of four levels, i.e 30, 45, 60 and 75 min. The treatment was repeated three times, so that would be obtained 12 trials. The treatment were effected significantly further tested with real honest test (HSD) at 5%. The results showed that the yields (75.22%) of sweet corn highest at the of 60 min boiling time, the viscosity (983 cp) of highest at the 45 min and the  emulsion stability (16.41%) of the best it was 30 min boiling time. The chemical properties were founded of the best such as water content (78.5%) at 60 min, sugar content (14.4%) at 45 min, protein content (3.36%) at 60 min, fiber content (0.45%) at 75 min and ash content (0.22%) at 60 min. Key Words : Boiling, corn milk, physical and chemical characteristics, sweet corn.

Abstract

High content of aluminum and low N availability in Ultisol are the important limiting factors for crop production. Hence, important efforts on management of Ultisol are increasing N availability for crop demand. Guano fertilizer and pruning of Lamtoro are source of organic matter used to improve the soil, although the two fertilizers still not yet have full attention. The present study was aimed to elucidate roles of Guano fertilizer and green manure of Lamtoro on Al concentration, N availability, crop growth and N uptake by maize in an Ultisol.  The study was conducted in a glasshouse. Combination of the two fertilizers at two different rates of each fertilizer (10 and 20 ton/ha) and one control (no fertilizer added) resulted in nine treatments and they were arranged in a factorial randomized block design with three replicates. Results of the experiment showed that the application of Guano fertilizer and Lamtoro green manure significantly reduced Alexch concentration, increased soil pH, increased N availability, improved maize growth and increased N taken up by maize grown for 45 days.

Abstract

The purposes of the research was to determine the effects of tuber sizes andpotassium fertilizerrates on growth and yield of Lembah Palu shallot varieties. This research was conducted in Simoro village, Gumbasa Sub District in Regency of Sigi. Laboratory work for yield component observations were done in Seed Technology Laboratory of Agriculture Faculty, Tadulako University. This research was conducted from June to August 2013. A randomized block design was used for designingthe research within which two factors were applied namely tuber size (U) and rates of potassium (K). The tuber size consist of small tuber (U1= 1.7-2.3gtuber-1) and large tuber (U2= 2.4-3.0 gtuber-1). The potassium fertilizer (K2O) consist of four rates; 100 kgha-1, 150 kgha-1, 200 kgha-1, 250 kgha-1. The research treatments was replicated three times. The results research showed that tuber dimension significantly affected all growth parameters except plant height and all yield parameters. The large tuber grew better than small tuber. While K rates showed significant effect for all growth parameters except shoot numbers and all yield parameters, except tuber number per plants. The rates of K above 100kgha-1 showed greater yield 6.41 tonha-1 than the low rate 100 kgha-1 only 5.66 tonha-1. There was a significant interaction effect between tuber size and rates of K fertilizer for all parameters growth, except leaf number and shoot number, and  all parameter yields except tuber diameter. The potassium fertilizerinfluence the growth, yield of and corm quality. The potassium fertilizer function is to strengthen the crop vigor along with forming and enlarging tuber diameter. Key words : K dosage, Shallot varieties lembah palu, Tuber size.

Abstract

In the last ten years, the performance of Indonesia’s cocoa agribusiness has been diminishing due to decreasing cacao estate area, cacao plant production and cocoa export volume. Cocoa agribusiness development strategies in Indonesia were analyzed using SWOT and Architecture Strategy, which on one hand were directed more to increase the performance of small holders cacao plantation by strengthening the role of farmer groups and optimizing the role of associations. On the other hand, the strategies for the government and private cacao estates are directed more to increase the volume of production and product diversification which are important for improving the export oriented cocoa products. Other strategies that can be implied are 1) increasing the promotional activity and 2) spreading the information about cocoa and its benefits in order to increase domestic cocoa consumption.Keywords : Cocoa Agribusiness and Road Map.

Abstract

The research aimed to identify the physico-chemical and sensory characteristics of aren instant starch noodle (ISN) substituted with 0, 5, 10, 15, 20, and 25% of tapioca starch.  The physicochemical and sensory characteristics observed were gelatinization level, water content, white degree, cooking rate, cooking loss, tensile strength, elongation, texture, performance, aroma, taste and viscosity.  Corn ISN was used as a comparison. The research results showed that the percentage of the tapioca starch that could substitute the aren starch was in the ranges of 5 – 20%.  Substituting with 20% tapioca starch could yield ISN most similar to the corn ISN in which physicochemical and sensory characteristics were acceptable to consumers.  However, the water content of the ISN resulted from the research still higher than that of standard category, therefore the time length for drying need to be prolonged.

Abstract

This research aimed at determining the optimal combination of integrated farming system inMajalengka in relation to land resource availability, production inputs, capital and credit. Data wasanalyzed using Linear Programming. The results of the research were (1) the optimal croppingpattern generated income more than IDR 1.34 billions, (2) with available credit and fertilizerassumption, the income obtained was more than IDR 1.61 billions, and (3) with availableproduction inputs and fertilizer assumption, the income received was more than IDR 1.64 billions.The study suggested that the credit policy increases land use and beef cattle number, thus increasefamers’ income.Key words : Integrated farming system, optimal solution, scenario and Majalengka.
