Abstract

Jajar legowo 4:1 cropping pattern has been adopted by rice farmers; however, there has been limited information on the comparison between internal and edge rows. In addition, the effects of timing and frequency of fertilizer applications on rice cultivated at riparian wetland also have to be understood. In this research, both single and split applications of fertilizer were employed. The single fertilizer applications were applied at 15 days after transplanting (DAT) (T1), 30 DAT (T2), 45 DAT (T3); and the split applications were 15+30 DAT (T4), 15+45 DAT (T5), 30+45 DAT (T6), and 15+30+45 DAT (T7). Results of this research indicated that crops in the edge rows produced higher leaf area index but those at internal rows produced higher dry weight biomass. Split fertilizer application to three times (T7) increased the weight of grains and number of filled spikelet but did not affect other shoot and root growth traits. Overall, fertilizer application increased leaf chlorophyll and nitrogen content. Jajar legowo 4:1 planting pattern and split fertilizer application to three times are recommended for increasing yield in rice cultivated at riparian wetlands.

Abstract

Mass propagation technology through somatic embryogenesis has become an alternative for producing sugarcane seedlings rapidly.Application of proper plant growth regulator and concentration contribute to support somatic embryogenesis development. This study applied the combination of liquid and solid culture during proliferation stage to promote cell dispersion of embryogenic callus, rapid  embryo somatic production, and improve regeneration potency of somatic embryo. Application of 2,4-D and coconut water during proliferation may expected as proper combination for accelerating somatic embryo development and regeneration.Development of somatic embryogenesis in sugarcane var. Bululawang during proliferation were described in this study. Embryogenic callusfrom induction media were transferred to proliferation media containing MS Basal + vitamin supplemented with sucrose different level of 2,4-D (1 mgl-1, 2 mgl-1, 3 mgl-1, 4 mgl-1 ) and coconut water (0% and 5%).Result showed that low concentration of 2,4-D induced optimum somatic embryogenesis development in proliferation and regeneration. Concentration of single 2,4-D 1 mgl-1 without coconut water  induced rapid development of scutelar and coleoptilarduring proliferation and resulted in better shoot regeneration. In other way, 4 mgl-1 of 2,4-D concentration  affected to inhibit scutelar and coloeptilar formed as the result of failure callus differentiation.

Abstract

Nitrogen (N) is an important nutrient for the growth and development of rice plants, required in large quantity and often limiting factor of rice yields. The research was to understand the different sources and levels of nitrogen in rice plant on the activity of N assimilation enzymes, including nitrate reductase (NR), glutamine synthase (GS) content, glutamate synthase (Gogat) content, content, ammonium (NH4+) and nitrate (NO3-) content on the leaves. Paddy (Ciherang variety) was grown in sand media containing Hoagland solution with different sources (ammonium and nitrate) and levels (0.4, 0.8, 1.6, 3.2, 6.4, and 12.8 mM) of nitrogen. Nitrogen assimilation was observed from leaves at one month of age. The NR activity increased on both Nitrogen sources, it was a higher activity in media contained nitrate. Also, the activity of GS showed higher in media contains nitrate, but its activity was decreased after application 1.6 mM of nitrate and 3.2 mM of ammonium. Western blot analysis of GS1 and GS2 showed that the band pattern of protein was similar to these enzyme activities. Nitrate content in leaves gradually increased in both sources of nitrogen and higher than 3.2 mM ammonium application caused an increase in ammonium content in leaves, but the nitrate content decreased. This research resulted that the available source of N for rice was in nitrate form, easily by the rice plants during the growth stage.

Abstract

Generally, vegetables cultivation in tropical riparian wetland is conducted only one times per year simultaneously or after rice cultivation. One of constrains of cultivation in tropical riparian wetland is low adoption to technology which can be used by local farmers during dry season. The objective of this research was to introduce result of research to local farmer directly and examine the local farmer’s adoption about the technology based on research to apply in tropical riparian wetland, Pemulutan, South Sumatera. Based on this research, results showed that farmers' interest in cultivating vegetables during the dry season is still low, but it has a chance to be improved. Alternative solutions through watering and adjustment of environmental conditions or adaptation through the selection of cultivation locations and the selection of various types of vegetable crops have been carried out by farmers. However, the application of mulch has not been practiced by farmers in tropical riparian wetland for vegetable cultivation during the dry season due to limited information received, considered as capital intensive, and the sociocultural aspects of the local community.

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.

Abstract

Drought condition during the dry season is a major constraint for intensifying agricultural activities at riparian wetlands in Indonesia, particularly for annual vegetables, including common bean (Phaseolus vulgaris L.). Besides inhibiting growth and reducing yield, drought also causes alteration of the shoot and root growth and development. The objective of this study was to evaluate responses of common bean to three durations of drought stress and the bean ability to recover after termination of the stress treatments. Gradual drought stress treatments were imposed by withholding all water sources to the treated plants. Three durations of drought stress imposed were 4, 8, and 12 days. The ability of the stress-treated plants to recover was evaluated at 7 days after termination of each treatment. The result of this study revealed that common bean was able to tolerate and recover from gradual water deficit for up to 8 days; however, prolonged water deficit for 12 days inhibited the growth of above-ground organs in common bean. Despite root regrowth during the recovery period, plants previously treated with 12 days of drought were unable to recover but those treated with shorter drought stress period were able to recover.

Abstract

The growth of leaf biomass can be predicted from an increase in the surface area and thickness of the leaves. Measurements of leaf biomass are approached with the fresh weight of the leaves. The relationship between biomass and leaf surface area commonly performed by regression analysis. The analysis requires assuming linear relationship between dependent variables and independent variables. Artificial Neural Network (ANN) is alternative that can be used to analyze the relationship of leaves and leaf biomass without requiring linear relationships. The research aimed to evaluate ANN performance in determining the fresh weight of pakcoy leaves based on leaf area parameters. Datasets in the study included leaf area datasets and length-width datasets. ANN architecture used Multi Layer Perceptron (MLP) with backpropagation. Ramsey’s test results showed that leaf area datasets is linier model and length-width datasets is nonlinier model. ANN performs well in predicting leaf fresh weight data on both nonlinear and linear models. The best ANN architecture for modeling the leaf fresh weight with leaf area is MLP (1-3-1) while the leaf fresh weight model with length and width is MLP (2-3-1).

Abstract

Dendrobium orchid is one of the ornamental plants with high economic value. Public interest in orchids, especially Dendrobium species is quite high and dominates the markets which make the seedling request also getting higher. The critical stage in determining the success of orchid seedling growth is also determined by acclimatization techniques. Differences in environmental conditions at the acclimatization stage can cause transpiration and interfere with nutrient absorption of plantlets. Chitosan as a natural organic material is a simple derivative of chitin which can function as a biofertilizer and bioimmuner. The purpose of this study was to determine the response of orchid seedling growth to the application of chitosan for the success of the acclimatization stage. The research method used a completely randomized design (CRD) with one factor, concentration of chitosan. The acclimatization stage using chitosan application with concentrations of 0 ppm, 2 ppm, 2.5 ppm, 3 ppm, 3.5 ppm, 4 ppm, 4.5 ppm and 5 ppm. The data obtained were then analyzed for variance with the F test at the 5% level. The treatment with significant effect was further tested with Duncan Multiple Range Test (DMRT) at 95% level. The results showed that the application of chitosan with a concentration of 3 ppm had a significant effect in increasing the parameters of plant growth percentage, plant height, number of leaves, leaf width, leaf length, root length, number of roots, and fresh weight of Dendrobium sonia orchid plants at the acclimatization stage.
