Abstract

            The objectives of this research were to study effects of some ameliorants (calcify dolomite, sea mud, and some biofertilizers) to some variables of C-organic, C/N, soil nitrogen, soil available P, N and P absorption, the infection of Bradyrhizobium and mycorrhiza, and soybean growth. This research was arranged in Randomized Complete Block Design with thirteen treatments and two replicates.  Provision of some amelioran exerted significant effects on numbers of root nodules, degree of mycorrhiza infection, and plant height of 5 week after planting (WAP). The best amelioran was calcify dolomite on which had positive responses to the increase of numbers of root nodules, degree of mycorrhiza infection, and plant height of 5 WAP. The second best was combination of Bradyrhizobium +Mos+ peat soil isolate mycorrhiza, which significantly increased numbers of root nodules, degree of mycorrhiza infection, and plant height of 5 WAP. The poor and the poorest ameliorants were sea mud+calcify dolomite and sea mud without dolomite, respectively, which caused reduction of numbers of root nodules, degree of mycorrhiza infection, and plant height of 5 WAP.

Abstract

MOL (Local Microorganism) is one of the key factors to determine the success in manufacturing of organic fertilizer. MOL can fully substitute EM4 (Effective Microorganism) widely being sold in market, as starter to accelerate composting process. The MOL in the experiment was produced from agricultural waste likes in consumable fruits. The experiment was aimed to investigate a better fermentation method in the production of MOL. A Split Plot Design with fermentation methods (with and without applying of air channel) as main plot and length of fermentation (0, 1, 2, 3, 4 and 5 weeks) as sub-plot were applied to produce MOL, with 2 replications. With air channel, the gas produced from the fermentation process could be channeled out of the fermentation container. Analysis of MOL quality included total microorganisms (TCC), temperature, pH, and color. In general, result showed that the MOLs produced from fermentations without air channel were better than the ones produced from with air channel. The highest amount of TCC in MOL was produced from 3 weeks fermentation without air channel.

Abstract

A field experiment was conducted to determine the growth responses of teak stump to NPK fertilizer that contains S nutrient. The stumps of teak were treated with Phoska fertilizer: 0, 5, 10, 15 g/plant and the fertilizer dosages were applied at 0, 5, 10, and 15 days after planting. The results of the study showed that stem diameter, stem height, and seedling height of the teak were significantly affected by the dosages and application times of Phoska fertilizer at 1, 2, 3, and 4 months after planting. The leaf numbers, leaf length, and leaf width responded significantly to Phoska fertilizer. This study found a significant interaction between the dosages and application times of Phoska fertilizer on seedling height and leaf length at one month old after planting; on stem height, seedling height, and leaf numbers at three month old; on stem diameter, stem height, seedling height, and leaf numbers at four month old after planting. The study revealed that the application of 10 g/plant Phoska applied at a planting day was the best treatment to enhance the growth of teak stump.

Abstract

ABSTRACT The aims of the research were to evaluate soil characteristics, to study land suitability and to propose recommendation of land use and rehabilitation of the tsunami affected agricultural area in Lhoong Sub-District. The result showed that soil textures were varied from very coarse at the area near the coastline to rather fine at the area far from the coast. The soil structures of topsoil were generally plate and blocky, and at subsoil generally massive. The quality of irrigation water in Sub District of Lhoong was still suitable for crops. The pH of water was neutral and low in salinity (0, 4 mS cm-1). The recommendations for land of class A were (1) cleaning and repairing of irrigation and drainage channel, (2) leaching of salinity in topsoil from soil profile by flooding method (irrigation basin) or furrow irrigation,  (3) making the ditches for cultivation in managing the excess of salinity, (4) establishing ditches for paddy, and (5) requiring a specified amount of water for the leaching processes and the amount of water required for crops. The recommendation for land class B were (1) cleaning and repairing of irrigation and drainage channel, (2) removing the sediment above the topsoil, (3) leaching the salt from topsoil passing soil profile  by irrigation water, (4) constructing ditches for cultivation in managing the  excess of salinity.

Abstract

            A study to determine a right concentration of organic fertilizer Super Nasa and type of organic mulches on growth and yield of soybeans has been conducted. The experiment used a factorial randomized complete block design 4 x 3 with 3 replications. Factors studied were concentrations of organic fertilizer Super Nasa, consisting of 4 levels: 0, 5, 10, 15 g/L of water and types of organic mulches, consisting of three levels: printing newspaper, bagasse, and paddy stalk. Results showed that the concentrations of organic fertilizer Super Nasa exerted highly significant effects on dried grain weight per plot netto and dried seed weight per hectare and exerted a significant effect on plant height 45 day after planting, but exerted no significant effect on other variables. The best growth and yield of soybean were found at a concentration of organic fertilizers Super Nasa 10 g/L of water. Types of organic mulches did not affect all variables observed. However, Soybean yield was apparently better at printing newspaper. There was no significant interaction between concentration of organic fertilizer Super Nasa and types of organic mulches on all growth and yield variables observed.

Abstract

The objective of this study was to test three types of plant spacing on two varieties of rice on growth, yield components, and yield of rice. This experiment used a Randomized Complete Block Design (RCBD) with 3 replications.  Factors studied were types of plant spacing and varieties. The results showed that the types of plant spacing significantly affected rice yield. However, the types of plant spacing did not significantly affect age of flowering, panicle length, and number of grains per panicle. On the rice yield variable, Legowo and triangle (hexagonal) types of plant spacing gave higher yields than rectangular type. Variety significantly affected age of flowering, panicle length, number of grains per panicle, and yield of rice. Pandan Wangi bloomed faster than Cot Irie line. However, Cot Irie line had longer panicles and more grain numbers, and higher yields than Pandan Wangi. There was a significant interaction between varieties and types of plant spacing on a number of productive tillers. On Pandan Wangi, the most productive tillers were found in a rectangular type of spacing, but not significantly different to a triangular type of spacing. The least number of productive tillers was found in a type of Legowo. However, on Cot Irie line, the number of productive tillers did not differ from each other among the types of plant spacing.
