Abstract

Rice ratoon system is one solution constraints of tidal rice fields, particularly the season and limitations of agricultural inputs. The ratoon’s quality highly dependent on the quality of main crop’s vegetative phase. The main crop with maximum vegetative phase, is predicted to produce high growth of ratoon. This study is the second phase of the three experimental stages of multi-year research of hibah bersaing. The first phase of the experiment (September 2013-May 2014) aims to give the height of singgang’s cutting to increase vigor vegetative and reproductive phase of ratoon in tidal land. This experiment is to obtain adaptive rice varieties with high potentially of ratoon in tidal rice fields. This experiment used a randomized block design factors, namely rice varieties (Sintanur, Margasari, Mekongga and Batanghari), with three replications, ongoing since March 2014-September 2014, located in experimental farm of Faculty of Agriculture, IBA University, in Palembang. Each treatment consists of 18 units of plant, so totaly contained 216 experimental units. Rice plants grown in soil media of tidal rice fields that brought from Telang Sari village, Tanjung Lago district, Banyu Asin regency, South Sumatera. The vegetative parameters consist plant height, panicle height, number of tillers, number of productive tillers, chlorophyl, flag leaf area and leaf area. The results indicate that the vegetative phase of Sintanur is the best, measured by plant height and panicle being, number of tillers and productive tillers highest, and flag leaf area and the largest leaf area. This experimental results imply that the quality of growth and vigor of Sintanur’s ratoon would be better than Margasari, Mekongga and Batanghari.

Abstract

Oil palm Plantation at Muaro Jambi, Jambi province already aged over 25 years, so these plants are not productive anymore and needs to be rejuvenated. By doing rejuvenation means farmers will lose income while waiting for the palm oil crop production for 3-4 years. Intercrop between oil palm plantations have great resulted in improved land productivity, increase farmers income as well as the main crop of palm maintained. Technological innovation between plants can be carried out on an oil palm plantation aged 1 to 3 years or before the plant produces. The aim is to optimize land use oil palm replanting with horticultural crops through the provision of organic matter and MPHP (Silver Black plastic mulch). The activities carried out in Mekarsari Makmur Village Muaro Jambi District. Horticultural crops that are cultivated eggplant, beans, bitter melon, squash and cucumber. The draft assessment used was a factorial randomized block design with two factors, namely: MPHP (MPHP Without and With MPHP) and the provision of organic material (Without organic fertilizers, Manure, Compost and manure + compost). For all commodities, the highest production was obtained at treatment MPHP use and manure, ie 20.9 tonnes of beans/ha, 8.99 tons of cucumbers/ha, 5.95 tons of squash/ha, 1.17 pare ton/ha and 6 , 8 tons of eggplant/ha

Abstract

Plants which experienced the stress immersion of photosynthesis and its respiration were hampered, as a result of gas diffusion and penetration of low light. Penetration of light that can be captured by the plant which experienced the stress immersion is highly depending on the turbidity of water and the height of immersion. Some rice varieties have different growth responses to the stress immersion at various water turbidity. This study aims to obtain varieties that are tolerant to stress immersion in various conditions of water turbidity. The experimental design used in this research is completely randomized design arranged in a factorial with two factors treatments and three replications. The first factor is rice varieties consists of IR 64 (V1), Inpara 3 (V2), and Inpara 5 (V3). The second factor is the turbidity of water immersion consists of without an immersion (K0), immersion in pure water (K1), immersion in ½ water turbid (K2), immersion in water turbid (K3). Submersion did on 7hst for 7 days. The results showed that rice crops which experienced the stress immersion in various water turbidity showed a response to agronomic character’s changing which is different, Inpara 5 varieties tend to be more tolerant of stress immersion in various water turbidity, the more turbid water immersion, the greater damage to the rice crop and the lower production of grain produced per hectare
