Performance of six new superior varieties of rice on tidal swamp-land in South Kalimantan Province

Abstract

Rice is the staple food for millions of people of Indonesia which produced from many agroecology including tidal-swamp. The contribution of swampland to the national rice production is still lower than 2%. One of the indigenous knowledge of the tidal-swamp farmers is the massive use of local varieties which have low yield. Therefore, efforts to increase rice production in tidal-swampland of Barito Kuala Regency should consider the use of superior varieties. The purpose of this study was to find out performance of seven superior varieties in tidal-swamp land in two planting seasons. This research was conducted from March 2020 to March 2021 in Karang Buah Village of Belawang District of Barito Kuala Regency, South Kalimantan Province. The research was arranged in two factors of Randomized Complete Block Design namely varieties and seasons. The first factor consisted of seven varieties: Inpari-42 (V1), Inpari-43 (V2), Inpari IR Nutri Zinc (V3), Inpara-8 (V4), Inpara-9 (V5), Inpara-10 (V6), and IR-42 (V7). The second factor, season consisted of season-1 which started from March to July 2020 and season-2 for planting period from November 2020 to March 2021. The result showed that swamp rice varieties had higher value for plant height variables than those of irrigated rice varieties with Inpari-8 as the highest one. However, all irrigated rice varieties performed better which had higher value for panicle number, filled rice grain, and yield with IR-42 as the highest one. All varieties except IR-42 showed higher values of filled grain numbers when cultivated in season-1 supported by good weather during the study.

Livelihood Alternatives in Restored Peatland Areas in South Sumatra Province, Indonesia

“…Several studies in the peatland areas of South Sumatra have shown a large dependence of rural households on work in the agriculture, forestry, fisheries, and livestock sectors. The income contribution of the agriculture, forestry, fisheries, and livestock sectors is approximately 40-65% of the total income of rural households in the peatlands of South Sumatra [5,7,40,43,59]. In OKI, the contribution to income from the agriculture, forestry, fisheries, and livestock sectors ranges from 40.18% to 56.92% which is similar to [75].…”

“…Therefore, further research and product development are required. Peatlands, owing to their hydrotopographic characteristics, are suitable ecosystems for planting food crops, especially rice [59,60]. Cultivating rice using the Sonor method has become part of the local knowledge of the people living around the peatland, in addition to catching and/or raising fish, swamp buffaloes, and using Purun.…”

Analysis of special rice farming income in supporting the reduction of stunting in Riau province

“…The contribution of swampland to the national rice production is still lower than 2% but it is possible to increase it considering the large area of land that has not been utilized. Therefore, swamp land is the future land for food production in Indonesia [10].…”

Minimum tillage on vertisols lowland increases rice production and soil properties

“…The advanced science and technology nowadays has answered many challenges on the efforts to increase rice productivity, such as the use of new varieties (Hasbianto et al, 2021), the optimal cropping systems (Abduh et al, 2020), the use of organic fertilizers (Amanullah et al, 2016), inorganic (Sheudzen et al, 2020), the soil amendment (Haque et al, 2021), the weed management (Parameswari and Srinivas, 2017), pests and diseases (Ning et al, 2017), and the postharvest (Danbaba et al, 2019). This information can be easily accessed through applications on android (Nutini et al, 2021).…”
