Abstract

Drought stress is one of the important issues related to the global warming that demand for the development of drought tolerant crops. Eggplant is one of the agricultural commodities which can be developed in dry land so plant growth of eggplant need to be learned. The objectives of this study were to study the effect of several concentrations of polyethylene glycol (PEG) on the in vitro growth of eggplant, and to find the drought tolerant eggplant accessions in dry land. The experiment  was conducted at the Laboratory of Tissue Culture, Department of Agronomy and Horticulture, Bogor Agricultural University. The experiment was laid on a completely randomized design with one factor. The factor was eggplant accessions. The results showed that PEG in vitro media significantly affected the survival percentage, the percentage of callus, developed the bud and the number of leaves of eggplant. Callus in eggplant explants as a way of avoiding drought stress.

Abstract

Lindiana, et al. Rice Cultivation Images by Local Farmers in Pemulutan District, Ogan Ilir, South Sumatra. JLSO 5(2):153-158. Plans and efforts in increasing rice productivity at riparian wetlands can be commenced by introducing relevant technologies; however, the selected technologies should be based on real needs or problems faced by local farmers. As a pre-requisite, if the needs and problems are not comprehensively understood, government intervention to introduce new technology may not be effective since the technology may not be relevant or affordable to local farmers. Objectives of this research are to analyze characteristics of the wetlands, farmer’s adoption capacity, and technological preferences. The research was conducted in five villages at Pemulutan District. Qualitative Grounded Theory and Quantitative Survey were employed through dialogues with 100 local farmers.  Results of the research indicated that any effort to increase riparian wetland productivity should consider the unpredictability of flood occurrences and prolonged drought. These unfavorable conditions have limited local farmers to only grow rice once per year. Local farmers were almost solely depending on rice and cultivation of other crops were rarely observed, except limited vegetables grown on elevated border of paddy fields.
