Abstract

Shallow water table (SWT) is an acute problem in cultivating vegetables at riparian wetland during transitional period from dry to rainy season. SWT limits volume of aerobic rhizosphere and reduces oxygen availability. Meanwhile, 5-aminolevulinic acid (ALA) has been known for its effectiveness in offsetting negative effects of abiotic stresses. The aim of this study was to evaluate effectiveness of ALA application at pre- or during continuous 20-day SWT exposure in snap bean. SWT exposures were set at depth of 5 cm (SWT-5), 10 cm (SWT-10) and 15 cm (SWT-15) below substrate surface. ALA was applied at 4 days before SWT initiation (14 DAP), mid of SWT exposure period (28 DAP), or at end of SWT exposure (38 DAP). Results of this study indicated that SWT exposure affected growth of shoots and roots, leaf water status, proline content, and SPAD value in snap bean plant. Shallowest water table (SWT-5) caused the most severe effects. Effectiveness of ALA application was depended on time difference between ALA application and onset of SWT exposure. ALA application did not significantly improve recovery of snap bean plants after SWT exposure was terminated.

Abstract

A successful development of low cost floating culture system (FCS) has opened an opportunity for local farmers to cultivate vegetables during prolonged flooding at riparian wetlands. Research was aimed to identify the optimal depth of water-substrate interface (WSI) and optimal rate of NPK fertilizer application (RFA) in cultivating green apple eggplant using the FCS. Depths of WSI were adjusted to 0, 1, 3, and 6 cm and substrate was enriched with 8.4, 12.6, and 16.8 g NPK per pot. The enriched substrates were contained in pots and placed on floating rafts with variable WSI depths. Experiment was arranged in Split Plot Design. WSI was assigned as main plot and RFA was as subplot. The results exhibited that direct contact between water surface and substrate significantly increased water moisture content, enhanced shoot growth, and increased fruit yield, regardless the WSI depths. However, WSI treatments decreased SPAD value and restricted root elongation when WSI depth was more than 3 cm. The RFA treatments up to 16.8 g per pot could enhance shoot and root growth, and increased the fruit yield. This yield increase was associated with the increasing number of fruits, not the fruit size.

Abstract

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.

Lakitan B. 2019. Double track strategy for agriculture development in indonesia: facilitating millennial generation and improving livelihood of smallholder farmers. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang  4-5 September 2019. pp. 1-8. Palembang: Unsri Press.Agricultural development in Indonesia has not been able to solve two main fundamental problems. Firstly, advancement of agricultural technology failed to significantly improve livelihood of smallholder farmers; instead, it creates wider gap between developed technology and farmer’s adoption capacity. Secondly, educated young generation who has capacity to employ sophisticated technologies has not interested to work in agriculture sector. In 2018, there were 38.7 million farmers in Indonesia, where as 88.27 percent of them were categorized as informal workers. This number was about one third of total Indonesian workers. They could be time bombs if they are not treated wisely. Their livelihoods should be appropriately improved. The efforts require availability of relevant, affordable, and profitable agricultural technologies. Meanwhile, at present, only few of the millennials interested to work in agriculture sector. This small group of millennial farmers should be encouraged to stay in agriculture, in order to motivate more young generation to follow them. Urban and peri-urban agriculture based on relevant technologies seems to fit well with millennial farmers.Keywords: agricultural development, millennial farmers, welfare of farmers, urban agriculture

Lakitan B. 2021. URBAN OLERICULTURE: Contribution to increase vegetable production for urban community. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 1-10.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Population increase directly affects food demand. Since the increase will be concentrated in urban area, this trend should be appropriately responded by intensifying urban agriculture activities. Urban agriculture characterized with limited availability of agricultural land but better infrastructure than rural area. Urban dwellers are also more prepared to adopt advanced agricultural technology and have better access to financial sources. Technology-wise, hydroponics and vertical agriculture have been practiced by urban farmers. Besides for food production, urban agriculture gives other benefits, including aesthetics and better quality of local environment. In major city, green wall and green roof have been developed at tall buildings. Vegetables and ornamental plants are the most commonly used in urban area. In some developed countries, indoor vegetable cultivation has been practiced using artificial lightings and large scale plant factories had employed automation system using artificial intelligence technology. Regardless of rapid development on agricultural technology, the selected technology for local application should consider availability of local natural resources and financial capacity of native farmers. Intensification of urban and peri-urban agricultural activities is not expected to fully meet total urban food demand. Therefore, conventional agriculture in rural area is still strongly needed.

Abstract

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

Abstract

Ridge gourd (Luffa acutangula) is a climbing vegetable that produces edible fruits. Young fruits are harvested when the cotyledons have not yet formed. This study covered morphological characteristics, growth behavior, and cultivation practices suitable for increasing the production of the ridge gourd in the urban ecosystem. Results of observation revealed the heart-shape leaf of the ridge gourd was very uniform and the leaf surface was flat so that their leaf area could be accurately estimated using leaf length and/or width (R2 > 0.97), yet leaf thickness was not a reliable predictor for the leaf area (R2 < 0.34). The length of the petioles was not correlated with the leaf blade area. Single leaves, multiple tendrils, bunches of male flowers and/or single female flowers, and one branch could be formed at each stem node. Water content in leaf blade was lower than in the petiole. This phenomenon is related to water favor loss due to transpiration activity. Nevertheless, the total conserved water within the leaf blade was 6.26 times more than that within the petiole. The process of fruit enlargement followed the Sigmoid curve. The upper-end curve flattened 10 days after the female flower bloomed. Moreover, at 10 days, cotyledon has not yet formed. Based on the leaf SPAD value, by time the fruit began to enlarge, 4-5 leaves at the stem base were instigated to show symptoms of senescence. Ridge gourd fruit fresh weight can be best estimated using the length x diameter as the predictor.

Abstract

Red amaranth (Amaranthus cruentus L.) is a fast-growing and nutritious leafy vegetable. The seed population density needs to be known appropriately to obtain the optimal yield of marketable sizes plants. The residue of black soldier fly (BSF) larvae culture has been recognized as a potential source of nutrients for cultivating red spinach plants. This study was designed to search for the best combination of plant population density and BSF concentration to obtain the optimal marketable yield of the red amaranth plant. In addition, an accurate leaf area estimation of the red amaranth plant was also developed using leaf dimensions as a predictor with several regression models. Two experiments were conducted. Firstly, the BSF residue was applied at a high rate (up to 50%) using a floating culture system. Application of the residue at the rate of 30% and higher significantly inhibited the growth of the red amaranth. Secondly, the application rate was reduced to 10% and 20%, and the experiment was conducted using the conventional cultivation system. Results indicated that the optimum application rate of the BSF residue was 10% for enhancing growth. Application of seed density at 30 mg/dm2 produced an optimum marketable yield of the red amaranth since a higher population density causes plant-plant competition. Thus, creating high size variability within the population or reducing the average size of the harvested plants. Lastly, the leaf area of red amaranth can be accurately estimated using the leaf length x width (LW) as a predictor using the zero-intercept linear regression model.

Abstract

A bulbil, as planting material, is difficult to stimulate to grow in a dormant state. This study examines the hydropriming effect on shoot emergence and the shading treatments on leaf and cormel growth during the vegetative stage. The priming was carried out by soaking the bulbils in distilled water for 0, 3, 6, 12, and 24 hours and the shading treatments at 0, 40, and 80 percent. The results show that the imbibition occurred immediately during the first 3 hours and continued to increase up to 24 hours. The bulbil re-drying process reached the pre-treatment water content in less than three days. Significantly the earlier emergence was observed in the plants exposed to the 80% shading. The petiole sheath breakup was not affected by the hydropriming and shading. The konjac planted in the shading treatment produced more sprouts, longer but slender petioles, larger but thinner leaves, and larger cormel size. The differences in fresh and dry weight were more related to tuber moisture content than the direct effect of the shading treatment. The SPAD value of konjac leaves immediately increased within a few days after the application of the NPK fertilizer and consistently lasted for four weeks.

Abstract

Chaya (Cnidoscolus aconitifolius (Mill.) I.M. Johnst.) is a perennial leafy vegetable. Since the leaf blade is the most crucial component of the Chaya, it should be advantageous to estimate the leaf area non-destructively.  This research aimed to (a) develop a beneficial non-destructive model for leaf area estimation, and (b) ascertain the impact of stem cutting diameter when used as planting material on chaya growth rate. The results demonstrated that utilizing the length x width (LW) of the middle lobe as the predictor and the zero intercepts linear regression LA = 1.679 LW with R2=0.947 determination coefficient was the most dependable model for Chaya plant leaf area estimation. The stem diameter, which ranged from 9.9 to 17.3 mm, had affected the shoot length, number of leaves, and canopy area between 5 and 7 weeks after planting (WAP). The variations in growth metrics diminished along with the age of plants. The diameter of the stem cutting used as planting material had no effect on the fresh weight of young edible shoot tip at 11 WAP. On Chaya plants that were cultivated with larger stem cutting diameters, the fresh leaf weight at the branch tips was heavier.
