Abstract

The use of fresh straw directly on agricultural land turns out have a negarif impact, among others, is the danger of grems contamination on the straw from theprevious crop and environmental pollution due to the formation of methane resulted from anaerobic decomposition of flooded rice field. The recommended solution is composting straw earlier. The main obstacle of this straw composting include necessary labor (preparation of materials, transportation, maintenance) and the cost is relatively high. An alternative solution is to do straw inoculation with bio agent consortium decomposers before tillage (direct composting). Inoculation consortium decomposer is added to the straw need to be tested its effect on decomposition rate, especially incubation time and incorporation also the type of consortium. The aim of this research is to determine the bio agent inoculant consortium decomposer incubation time to accelerate straw decomposition and nutrient availability. The experiments was conducted in the greenhouse of the Faculty of Agriculture University of Padjadjaran in April to May 2010, using a randomized block design in factorial pattern repeated three times, as factor I: Incubation time (1, 2, 3 and 4 MST) and factor II: inoculant: no inoculants; formula A = inoculant decomposers (Bacillus sp, Cytophaga sp, Streptomyces sp) and formula B = inoculant decomposers (Bacillus sp, Cytophaga sp, T. harzianum). The results of this experiment showed that administration of a consortium of formula A and B can accelerate the decomposition of straw (temperature increases and pH decreases), and with increasing incubation time can increase the value of C-organic, N-total, decrease C/N compared to controls.

Abstract

The use of supreme paddy varieties is one of the major technologies, which canincrease paddy productivity. With the availability of paddy varieties that has beenreleased by government, farmers are now able to select varieties that compatible to thelocation, high yield, and high selling value. Every paddy varieties require differentmanagement, in order to obtain optimal production is necessary to adjust the varietiesand cropping methods for a certain environment in obtaining the desired level of resultswith limited land area. The difference yield from each different spacing is not as much aseach different variety. Based on those things, the study was conducted in order todetermine the growth characterization and yield of several paddy varieties with differentspacing on irrigated soil. The research was conducted from April to August 2009, inKabupaten Karawang, using Split Plot Design with four replications. The main plot:plant spacing (20 cm x 20 cm and 27 cm x 27 cm), while the subplot: paddy varieties (4Hipa Ceva, Hipa 6 Jete, SL8 SHS and Ciherang). Research shows: no interactionbetween the spacing of rice varieties to growth characterization and paddy yield. Theresult of independent test shows that the different spacing has en effect on growthcharacterization and paddy yield. Spacing of 27 cm x 27 cm, showing the number oftillers per hill, percentage of filled grain per panicle, filled grain weight per hill and thehighest yield per plot 7.17 tonnes per hectare. Different paddy varieties influence growthcharacterization and paddy yield. SL8SHS and Ciherang varieties produce a low numberof tillers, but shows the highest percentage of filled grain per panicle, filled grain weightper hill and the highest yield per plot with results of each 7.47 and 7.37 tonnes perhectare.
