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.

Conidial density and viability of Beauveria bassiana and Metarhizium anisopliae grown on the low-pH in vitro medium. Liquid bioinsecticide with active ingredient from conidial entomopathogenic fungus has major constraints, namely short shelf life due to declining conidial viability and density is caused by low pH in the bioinsecticide carrier. This experiment aimed to measure the loss of conidial viability and density of Beauveria bassiana and Metarhizium anisopliae isolates grown on in vitro medium with low pH. Entomopathogenic fungus isolates were used as much as 28 isolates grown on in vitro medium at low pH, namely pH 5, 4, 3, and 2. The results showed that the fungus isolate that had the highest conidial density on in vitro medium at pH 5 was found on isolates of B. bassiana with code BPcMs (2.583 x 109 conidia mL-1), while the lowest one was found on isolates of B. bassiana with code of BWS Pantura (0.825x109 conidia mL-1). All isolate conidial density from in vitro medium with pH 2 decreased regularly. Conidial density of BPcMs isolate decreased to 2.483 x 109conidia mL-1, as well as BWS Pantura isolate also decreased to 0.425x109 conidia mL-1. The highest conidial viability at pH 5 was found on isolates of B. bassiana with code of BPcMs (51.572%), while the lowest conidial viability was found on isolate of B. bassiana with BTmPc code (15.040%). At pH 2, almost isolates tested had low conidial viability. The conidial viability of isolates BPcMs decreased to 47.037%%, while the isolates BTmPc also decreased to 12.778%. Therefore, the lower of the pH of the in vitro medium was, the lower of conidial viability and density of B. bassiana and M. anisopliae was

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.

Inclusive and Sustainable Management of Suboptimal Lands for Productive Agriculture in Indonesia Benyamin Lakitan

There are uncountable research activities and technology development efforts have been carried out in Indonesia; however, very limited economically and/or socially beneficial technologies have been created. Very few indigenous technologies have been used in producing goods and providing services, including in agricultural sector. This problem is rooted on facts that most of the technologies developed are not relevant to real needs and/or problems of domestic farmers. Even if the technologies are substantially relevant; in many cases, they are not finacially affordable by domestic farmers, do not significantly increase profit if used, and/or less competitive compared to similar available technologies in the market. Limited availability of resources, at present and even more scarse in the future, elevates expectation on technology to contribute in establishing inclusive, productive, and sustainable agricultural development. To assure that developed technology will be relevant to the needs and contribute to agricultural development, farmers ought to be play significant active roles during priority setting, planning, and developing the technology. The real issues at present are increase in food demand as consequence of population growth and conversion of arable lands for uses in other sectors. These trends have led to intensifying agricultural activities on suboptimal lands. Efforts to increase agricultural productivity in suboptimal lands should not jeopardize sustainable function of the ecosystem and participation of local farmers. Sustainability and inclusivity should be maintained while increasing productivity. Traditional knowledge and local wisdom have to be treated as reference for developing technology for establishing productive agriculture on suboptimal lands.

Lindiana, et al.Â Rice Cultivation Images by Local Farmers in Pemulutan District, Ogan Ilir, South Sumatra. JLSO 5(2):153-158.Â 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, farmerâ€™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.Â 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.

Jaya KK, Lakitan B, Bernas SM. 2020. Tiller size and water table effects in celery growth on floating cultivation system. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 184-191.Riparian wetland is highly available and potential suboptimal lands for an alternative solution in extending agricultural activity, but several constrains need to be resolved. The objective of this study was to improve the diversification of vegetables for increasing riparian wetland with utilizing floating cultivation system. This study was conducted From November until December 2019 in Jakabaring (104Â°46â€™4â€ E; 3Â°01â€™35â€ S) Palembang. The design of experiments used in this study was arranged in split plot-completely randomized design with 2 factors (main plot and sub-plot). Main plot was the height of water table, namely: R1 (1 cm upper raft surface), R5 (5 cm upper raft surface), and R10 (10 cm upper raft surface). Sub-plot was the size of celery tiller, i.e., B1 (big size) and B2 (small size). Each combination treatment consisted of five replication. Results showed that there was no any significant effect on water table and tiller size combination treatments in all observed variables, such as: plant height, leaf area, number of petioles, root length, fresh weight, and dry weight of shoot and roots. But, root length was significant different in water table treatment. Therefore, cultivated celery using floating culture system from tiller of parent plants can be an alternative to increase agriculture activity by shortening the planting period to increase vegetable diversification in riparian wetland.
