Abstract

The increme of Wetland Rice Production with New High Yieldding Varieties The use of high yielding variety (HYV) is one of the technology components that supports rice production, besides fertilizer and irrigation. Yet the use of HYV is still slowly adopted, resulting in continuing previous varieties application. The objectives of the research were to determine the HYV with the highest yield implementing integrated crop management (ICM). The location of research was in Tanjung Sari village, Pondok salam subdistrict, Purwakarta residence in 2009 dry season. The new seven HYVs (Inpari 1, Inpari 2, Inpari 3, Inpari 4, Inpari6, Inpara 2, and Aek Sibundong) were treated with randomized complete block design (RCBD) with four replications. The results showed that Aek Sibundong variety had the highest crop height, the number of panicle per hill, and the filled grain percentage. Aek Sibundong variety had 11.7 t/ha grain yield, while that Inpari 2 had 8.26 t/ha. There were significant correlation between dry yield and the number of panicle per hill and the number of grain per panicle, with the value of 4.470 and 0.479, respectively.

Abstract

The Use of Aglaophenia sp. Marine Biota Extract to Control Fusarium oxysporum f. sp. vanillae, a Pathogen of Vanilla Stem Rot The use of marine biota for organic fungicide material has enormous potential to be developed. The organic fungicide was directed to substitute synthetic fungicide for vanilla cultivation. Application of synthetic fungicide degraded environmental quality, therefore its applications does not support sustainable agriculture. The objective of this research was to know the potence of Aglaopheniain suppressing the growth of F. oxysporum f. sp.vanillae, the pathogen of vanilla stem rot. The research was done in green house in order to find the best substance for formulation of the extract. The substances screened were water, tween-80, and detergents with two different concentrations. Subsequently, two best formulas were chosen to apply in endemic area in Tabanan. The green house and field trial research used Randomized Completely Design with three and five replications respectively. Results showed that tween was the best substance used for formulation and concentration of 0.2% was better than other concentrations. The extract diluted in tween-80 on the concentration of 0.2% showed the lowest rot on stem, longest shoot, and the most leaves on vanilla shoot. Because of its significant performance, the 0.1% extract ofAglaopheniain 0.1% tween-80 was proposed to be the best formula to suppress the vanilla stem rot disease.
