Abstract

The research was aimed at identifying  physiology aspects of elephant grass to the cutting interval and height and different water giving. The research was carried out at experimental garden BPTP Gowa, Pa Bentengan Village Bajeng Sub-district Gowa Regency, South Sulawesi Province, carried out from May until September 2007. The research method was arranged based on split-plot-design in group random design consisting of three repetitions. The treatment arrangement was as follow: main plot S was with and without watering. Sub-plot was the cutting height (T) consisting of three levels, I,e. 10 cm cutting height from the ground surface, 20 cm cutting height from the ground surface, and 30 cm cutting height from the ground surface. The sub plots were the cutting interval consisting of three levels, i.e a-4-week cutting interval, a-6-week cutting interval, and an-8-week cutting interval. The research result showed than an-8-week cutting interval and 20 cm cutting height gave the highest mean at: photosynthesis speed, internal CO2 level, number of saplings, wet and dry weight of plants and small stomata conduct. Water giving gave the highest mean at: photosynthesis speed, internal CO2, number  of saplings, wet and dry weight of plants, while without water giving gave the highest mean at stomata conduct and transpiration speed.

Abstract

The research was aimed at analyzing the growth and nutrition value of elephant grass under different cutting interval times. The research was carried out at the experimental garden of BPTP Gowa, Pa Bentengan Village, Bajeng Sub-district, Gowa Regency, South Sulawesi Province from May 2007 to March 2008. The research utilized a random block design, with 4 treatment levels, i.e.: (1) a four-week cutting interval, (2) a six-week cutting interval, (3) an eight-week cutting interval, (4) a ten-week cutting interval. Each treatment was repeated 3 times, so that 12 treatment units were obtained. The research results showed that the four-week cutting interval produced the best growth and production components such as increased plant height (cm day-1), leaf number (leaf day-1), poll number (poll day-1), wet and dried weight (ton ha-1year-1)   The analysis of nutrition value indicated that the 4 week-cutting interval yielded higher water level and crude protein, but lower crude fat and fiber.

Abstract

Data in 2012 explained that Indonesia had dry land about 148 million ha (78%) and wetland by 40.20 million ha (22%) out of 188.20 million ha of the total land area. The variety of rice which can grow and produce well on marginal land such as gogo rice is very indispensable. This research aimed to find the gogo rice cultivars that can germinate normally in particular osmotic pressure and the tolerance limit on the drought by using PEG 6000 solution. The research was prepared with two-factor factorial design by using Completely Randomized Design. The first factor consisted of three gogo rice cultivars, namely 1. siang, 2. Pulut ko, and 3. roda, while the second factor consisted of four treatments, namely 1. water as control of 2. -1 bar, 3. -2 bar, and 4. -3 bar.Thus, there were 12 combinations of treatment in which each treatment was repeated four times. In the experiment Rolled Paper placed in plastic test method was used in which there were 50 items in each experiment unit.The variable observed was potential for growth, percentage of germination, and germination rate. The research findings reveal that the three cultivars were able to germinate normally only up to -1 bar osmotic pressure, while the pulut cultivar had higher germination capacity compared with siang and roda cultivars up to -3 bar PEG 6000 osmotic pressure. Siang cultivar and -1 bar osmotic pressure gave potential for growth, germination capacity, and germination rate.
