“…Rice is planted by using transplanting method, i.e., starting from seedling and then transplanted to rice fields (Lakitan et al 2018a,b). Rice seedling can be carried out with three patterns consisting of floating raft seedling, 'samir' method and digging ('tugal') method (Herlinda et al 2018a;Lakitan et al 2018b). Subsequently, seedlings of 7−10 days old are transplanted into rice fields.…”

Abstract. Karenina T, Herlinda S, Irsan C, Pujiastuti Y. 2019. Abundance and species diversity of predatory arthropods inhabiting rice of refuge habitats and synthetic insecticide application in freshwater swamps in South Sumatra, Indonesia. Biodiversitas 20: 2375-2387. Rice cultivation in freshwater swamps in Indonesia is specific, among other things, there is no synthetic pesticide spraying and vegetable growing on rice field embankments. This specific cultivation technique can affect the abundance and diversity of rice-dwelling arthropods species. The study aimed to compare the abundance and species diversity of predatory arthropods inhabiting rice surrounded both by refugia and vegetables and by those being applied with synthetic insecticide in the rice field of freshwater swamps. This study used rice plots surrounded by refugia flower (Zinnia sp., Tagetes erecta, Cosmo caudatus, and Sesamum indicum); vegetables (Cucumis sativus, Vigna sinensis, Luffa acutangula, and Momordica charantia); untreated; and synthetic insecticide. Twenty-five herbivore species of 12 families, 34 spider species of 8 families, and 24 species of predatory insects of 12 families were found on rice during a planting season. The lowest herbivore population and spider abundance were found on synthetic insecticide sprayed rice and they were significantly different from those of refugia-rice plots. The most abundant spiders and predatory insects were found on rice surrounded by refugia and were not significantly different from those of rice surrounded by vegetables. The highest species diversity for spiders and predatory insects was found on rice surrounded by refugia, whereas the lowest species diversity was found on synthetic pesticide sprayed rice. Therefore, rice surrounded by refugia flowers and vegetables was the most appropriate for habitat and niche of predatory arthropods.

“…Agriculture development on tidal swamp has been more advanced than that on non-tidal swamp in Indonesia, including the non-tidal wetland. Most farmers on non-tidal wetland in South Sumatra, for instance, are still practicing low-input traditional agricultures, resulting in low productivity (Lakitan et al, 2018b). They also only grow single rice crop annually.…”

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 sociallyacceptable 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.

“…Same study also reported that the two wider spacing recorded the highest values for panicle weight and length, the number of filled grains per panicle, and 1000-grain weight. More studies on the effects of planting density on agronomical characteristics of rice are available in the previous works [24,[38][39][40][41][42][43] . For the effects of row spacing on canopy structure and yield in different rice cultivars, Zhao et al [31] showed that the percentage of productive tiller was first reduced before it was increased with increasing of row-spacing following a quadratic regression pattern between row spacing and the percentage of productive tiller.…”

This paper presents the study reports on evaluating a new transplanting operation by taking into accounts the interactions between soil, plant, and machine in line with the System of Rice Intensification (SRI) practices. The objective was to modify planting claw (kuku-kambing) of a paddy transplanter in compliance with SRI guidelines to determine the best planting spacing (S), seed rate (G) and planting pattern that results in a maximum number of seedling, tillers per hill, and yield. Two separate experiments were carried out in two different paddy fields, one to determine the best planting spacing (S=4 levels: s 1 =0.16 m×0.3 m, s 2 = 0.18 m×0.3 m, s 3 =0.21 m×0.3 m, and s 4 =0.24 m×0.3 m) for a specific planting pattern (row mat or scattered planting pattern), and the other to determine the best combination of spacing with seed rate treatments (G=2 levels: g 1 =75 g/tray, and g 2 = 240 g/tray). Main SRI management practices such as soil characteristics of the sites, planting depth, missing hill, hill population, the number of seedling per hill, and yield components were evaluated. Results of two-way analysis of variance with three replications showed that spacing, planting pattern and seed rate affected the number of one-seedling in all experiment. It was also observed that the increase in spacing resulted in more tillers and more panicle per plant, however hill population and sterility ratio increased with the decrease in spacing. While the maximum number of panicles were resulted from scattered planting at s 4 =0.24 m×0.3 m spacing with the seed rate of g 1 =75 g/tray, the maximum number of one seedling were observed at s 4 =0.16 m×0.3 m. The highest and lowest yields were obtained from 75 g seeds per tray scattered and 70 g seeds per tray scattered treatment respectively. For all treatments, the result clearly indicates an increase in yield with an increase in spacing.
