Abstract

Water use efficient varieties in rice may have good opportunity in term of economic value and scarcity of water. This study was conducted to determine water consumption among rice genotypes that conventionally cultivated as low land (IR64, IPB97-F-15, Ciherang, Mentik Wangi, and Rokan hybrid), up land (Jatiluhur, Silugonggo), and amphibian type (Way Apo Buru, that could be planted both as lowland and up land). Rice seedlings at 14 days old were transplanted in a plastic container containing 83 kg of air dried soil, 1 plant per whole and 6 plants per container. The experiment was conducted in a vinyl house, using randomized complete block design with three replications. During rice growth, water table was maintained at 2 cm above soil surface, and water was added and recorded weekly. The results showed that varieties reveal production components and yield were different significantly. Water consumptions among varieties were significantly different, ranged from 15.93 L plant-1 for IR64 to 24.13 L plant-1 for Jatiluhur, or equal with 3,639 to 4,827 m3 ha-1. Jatiluhur was the most efficient variety in using water. This finding may guide us to explore benefit of water use efficient variety as sustainable option in water management of rice cultivation.

Abstract

The productivity of forage is strongly influenced by cutting height and interval of defoliation. Experiment was conducted at the Research Institute for Industrial Plants and Other Palm (BALITKA) Manado since June 2008 until April 2009. The objective of the experiment was to find out the effects of intensity and intervals of defoliation on dry weight production and the quality of nutrients. The experiment was arranged in factorial RCBD. The intensity of defoliation was based on cutting height, i.e. 5, 10, 15 cm, whereas the intervals of defoliation were 30, 45, 60 day and 456.54 Degree Days (DD). The data of dry weight production, leaf stem ratio, nutrient quality were collected. The results showed that there were significant effects of treatments on all parameters. Productivity of B. humidicolai terms of high dry weight yield, high leaf stem ratio and crude protein, low crude fiber and acid detergent fiber (ADF) content were found in the interaction of intensity 10 cm with the interval of defoliation among the vegetative development stage of 30 and 45 days, as well as the interval of defoliation based on heat unit accumulation of 456.54 DD. The research implies that a cutting height at 10 cm and interval of defoliation as mentioned above is ideal for B. humidicola. Utilization of growing degree days (GDD) to determine the appropriate time for defoliation is considerable under this experiment.Keywords: B. humidicola, defoliation, forage, nutrient, productivity
