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.

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.

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.

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.

Productivity and cropping intensity on non-tidal wetland in South Sumatra are considerably low and has been underutilized up to now. The majority of farmers in this ecosystem are smallholders with limited adoption capacity on introduced technologies and modern agricultural practices. The objectives of this research were (1) to comprehensively capture multidimensional constrains that restrained local farmers in increasing their agricultural productivity; and (2) to identify, assess, and develop substantially-relevant, financially-affordable, and socially-acceptable agricultural technologies and practices for smallholder farmers to increase productivity. This research was organized in three main activities: qualitative research employing Grounded Theory procedure, quantitative questionnaire-guided survey, and a series of laboratory and field experiments. The research results indicated that the main constraints in increasing productivity and cropping intensity on the non-tidal wetland in South Sumatra include (1) unpredictable flooding occurrence and low soil nutrients content (agronomic constraint), (2) low financial and technology adoption capacity of local farmers (economic constraint), and (3) public policy has not significantly escalated farmer’s motivation to increase food production (social and institutional constraint). This research suggests that multidimensional (technical, financial, ecological, and socio-cultural) approaches should be integrated in collective efforts for sustainably intensifying food production on the non-tidal wetland.

Lumbantoruan SM, Anggraini S, Siaga E. 2021. Potential of biofertilizer in optimizing corn growth in drought stress of peatlands. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 162-171. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Peatland is suboptimal land which has high potential to be used as agricultural, but the potential of this peat soil has challenges that are not easy to manage in a sustainable manner. Incorrect management can result in peatlands experiencing drought stress. A technological approach that can be used to optimize the use of peat soil that is experiencing drought stress in maize can be done by applying biological fertilizers. The results of this study are expected to optimize the growth of maize in drought stress peat soils. The design used in this study was a completely randomized block design with 2 treatment factors, namely the first treatment factor for biological fertilizers, namely H0: without mycorrhizae, H1: Mycorrhizae + Petrobio, H2: Mycorrhiza + Agrozeabiochar, H3: Mycorrhizae + Pugam. The second treatment factor was the intensity of watering, namely P1: Watering once a day, P2: Watering once in 3 days, P3: Watering once in 5 days, P4: Watering once in 7 days. The results showed that the application of biological fertilizers was able to increase the average plant height, stem diameter, and root length. Biofertilizer Micoriza + Petrobio was able to increase plant height by 11.7 cm and biological fertilizer Micoriza + Pugam (H3) was able to increase stem diameter by 1.3 and root length by 115.7 in drought stress peat soil compared to control.

Budidaya tanaman sistem terapung dapat menjadi salah satu altenatif solusi yang dapat dikembangkan di lahan tergenang. Pembibitan padi dan budidaya sayuran terapung dapat dilakukan di lahan rawa lebak selama periode banjir. Secara kearifan lokal, pembibitan padi terapung sudah dilakukan oleh para petani di Pemulutan, Sumatera Selatan menggunakan rumput rawa Scleria poaeformis, namun cara pembibitan tersebut mulai ditinggalkan seiring dengan menurunnya ketersediaan rumput rawa tersebut. Penggunaan rakit alternatif berbahan utama botol plastik bekas menjadi alternatif yang dapat diterapkan petani untuk mempertahankan pembibitan padi terapung. Pembibitan terapung menggunakan rakit botol plastik bekas memiliki keunggulan diantaranya tidak perlu penyiraman secara manual, benih yang digunakan sedikit, rakit dapat digunakan berulang, sedikit terserang hama ulat dan biaya pembuatan rakit murah. Selain pembibitan padi, kegiatan budidaya sayuran daun seperti sawi hijau juga dapat dilakukan. Sawi hijau hanya membutuhkan waktu kurang lebih 25 hari sejak bibit pindah tanam sehingga petani dapat panen berkali selama periode banjir. Dari hasil diseminasi yang dilakukan, diketahui bahwa terdapat ketertarikan yang tinggi petani untuk melakukan budidaya tanaman terapung dengan alasan diantaranya yaitu cara budidayanya praktis, pertumbuhan dan hasil baik, dan menjadi alternatif bagi petani untuk tetap dapat melakukan budidaya tanaman walaupun dalam kondisi lahan banjir yang berpotensi menambah pendapatan petani. Kata Kunci: budidaya terapung, pembibitan padi, sawi hijau, rawa lebak

Salah satu aspek penting dalam budidaya tanaman adalah pemupukan. Pemupukan yang baik dan berimbang akan berdampak positif bagi kelangsungan tanaman. Penggunaan mikroorganisme lokal ekstrak daging keong mas pada media air kelapa, sebagai pupuk alternatif adalah bentuk teknologi tepat guna dalam mendukung konsep pertanian terpadu dan berkelanjutan. Penelitian ini bertujuan untuk mendapatkan produk formula mikroorganisme lokal ekstrak daging keong mas pada media air kelapa, yang mampu meningkatkan pertumbuhan tanaman. Percobaan ini menggunakan rancangan acak kelompok (RAK) dengan 5 perlakuan, yang terdiri atas kontrol positif (NPK Mutiara), Kontrol negatif (akuades) dan 3 perlakuan penyiraman dengan formula MOL. Indikator pertumbuhan tanaman yang diamati adalah tinggi tanaman, jumlah daun, panjang akar, diameter batang, berat basah dan kering tanaman. Data hasil penelitian dianalisis secara sidik ragam menggunakan aplikasi statistik 8, jika berbeda nyata maka akan diuji lanjut menggunakan LSD pada taraf 5%. Secara keseluruhan, hasil penelitian menunjukkan introduksi MOL ekstrak keong mas pada media air kelapa berbagai konsentrasi, mampu meningkatkan pertumbuhan tanaman. Masing-masing perlakuan memberikan efek yang berbeda dalam meningkatkan pertumbuhan. Analisis sidik ragam terhadap efektivitas Mol ekstrak keong mas pada media air kelapa berbagai konsentrasi sebagai pemacu pertumbuhan, didapatkan perlakuan B (konsentrasi 5%) sebagai perlakuan terbaik. Hal ini terbukti dari kemampuan konsentrasi tersebut dalam meningkatkan tinggi tanaman, panjang akar, berat kering dan basah tanaman tanaman mentimun. Oleh karena itu, perlakuan tersebut berpotensi untuk dikembangkan sebagai biofertilizer, pengganti pupuk kimia sintetis dalam memacu pertumbuhan tanaman dan pemenuhan kebutuhan pemupukan.
