Abstract

Mechanism of Rice Adaptation at Drought Stress Conditions and Effort to Prevent Crop Failure Harvest losses of rice caused by drought is about 15-20% every year, so it needs rice varieties that can adapt to the conditions referred to in order to harvest losses can be reduced. To get the rice varieties that can adapt to environmental conditions such as drought, then the required information in advance about the properties owned by the rice plant varieties capable of responding to drought conditions. This paper is organized with the aim to study the mechanisms of adaptation of plant varieties of rice in drought stress conditions. Adaptation mechanisms are grouped into two main groups namely, anatomy morphological adaptation mechanism and physiology biochemical mechanisms of metabolic adaptation. Morphological adaptation mechanisms include anatomic distribution properties and root growth, maintain plant water potential, canopy temperature, the leaves curl and abort. Biochemical adaptation mechanisms include metabolic physiology traits ability to synthesize secondary metabolites such as ethylene and abscisic acid, osmotic adjustments such as increasing accumulation of sugars, amino acids and proline. Furthermore, to prevent crop failure takes effort to implement cultivation techniques schedules and cropping patterns, planting drought-resistant varieties, and the addition of organic matter.

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 solubility of aluminum (Al) which is high in acid soils is unavoidable. Solutions or strategies thatcan minimize the adverse effect of Al on soybean need to be obtained, by studying the response ofplants to Al. Al intoxication is a limiting factor for plant productivity. The purpose of this research wasto study the effects of salt form of aluminum complexes with organic acids and salts of aluminumcomplexes with inorganic acids on the rate of photosynthesis and chlorophyll content of soybean (Glycinemax) in the acidic growth medium. Research has been carried out experimentally in the greenhouse ofAgriculture Faculty Gadjah Mada University. The design used was Completely randomized design(CRD) with factorial pattern, and two-factors. The first factor was the kind of aluminum salt consistingof three kinds: without Al, Al-nitrate salt and Al-lactate salt. The second factor is the level of mediumacidity (pH) of growth medium with three level of pH value: pH 4, pH 5 and pH 6. Each treatment wasrepeated 3 replications. Variables that were observed included leaf area, the rate of photosynthesis andchlorophyll content. The results showed that the salt form of Al may affect rate of photosynthesis andchlorophyll content. complex Al salt form with organic acids (Al-lactate) can cause photosynthesis ratecompares favorably with the Al-nitrate.
