“…Penggunaan varietas unggul yang cocok dan adaptif merupakan salah satu komponen teknologi yang nyata kontribusinya terhadap peningkatan produktivitas padi, cepat diadopsi petani karena murah dan penggunaannya lebih praktis (Saidah et al, 2015). Varietas unggul yang mampu beradapatasi dengan lingkungan yang spesifik dapat memberikan hasil yang lebih optimal daripada varietas dengan adaptasi luas (Zein, 2012).…”

“…Kondisi demikian memungkinkan tanaman dapat memanfaatkan secara optimal cahaya matahari yang jatuh ke permukaan daun, sehingga meningkatkan laju fotosintesis dan selanjutnya dapat mendorong pertumbuhan dan perkembangan tanaman yang lebih baik. Ketersediaan cahaya matahari yang optimal dapat meningkatkan source dan kekuatan sink pada tanaman padi (Saidah et al, 2015). Sementara Razie et al (2013) melaporkan bahwa produksi padi Ciherang di lahan pasang surut dengan budidaya SRI hampir 22% lebih tinggi dibandingkan dengan budidaya konvensional.…”

ABSTRACT The efforts to develop and increase rice production in tidal land need appropriate technologies including adaptable superior varieties and efficient seed planting system. This study was aimed to measure the agronomic characteristic of the three rice varieties on the systems of in-row direct seeding and broadcast in tidal land. The experiment was carried out at type B of tidal land in Sidoharjo Village, Air Saleh Subdistrict, Banyuasin District, from January to April 2016. The experiment was conducted using split plot design with four replications. The main plot was seed planting system, consisted of in-row direct seeding system and broadcast system; whereas subplot was three rice varieties, consisted of Inpari 22, Inpara 4, and Ciherang. Result of LSD test on interaction showed that though the best growth was obtained from the combination of Inpari 22 and in-row direct seeding and very significant with the others, but its yield was not significant with the combination of Inpara 4 and in-row direct seeding. It was concluded that Inpari 22 and Inpara 4 with in-row direct seeding system showed better growth and higher yield than Inpari 22, Inpara 4 and Ciherang with broadcast system in tidal lands. Ciherang was not suitable in tidal land, while Inpari 22 was suitable. Keywords: broadcast system, in-row direct seeding system, production

The increasing demand for shallots is inversely proportional to the quality of the current production. Efforts to improve and increase quality of production are selection of good varieties and add plant regulatory substances has also become the focus of many researchers in their effect on plant growth. Therefore, research was carried out on the effect of the varieties and also plant regulatory substances namely paclobutrazol on the growth and production of shallot plants. This research was carried out at the Teaching Farm, Faculty of Agriculture, Hasanuddin University from August to November 2021. This research was carried out as a factorial experiment in a split plot design, as the main plot, namely the botanical seed varieties of shallot (v) consists of 3 varieties, namely the Lokananta varieties (v1), Maserati varieties (v2), and Sanren varieties (v3), as a sub-plot, namely the concentration of paclobutrazol consists of 4 levels, namely 0 ppm (k0), 100 ppm (k1), 200 ppm (k2) and 300 ppm (k3). The research results showed that the interaction of the Sanren varieties with paclobutrazol concentration of 100 ppm gave the best results on the weight of fresh stover per plant (26.04 g), weight of dry stover per plant (19.23 g) and production per hectare (9.20 ton/ha). The Sanren varieties gave the best results on chlorophyll a (387.23 μmol.m−2), chlorophyll b (187.12 μmol.m−2), total chlorophyll (564.14 μmol.m−2) and number of tubers (1.81). Paclobutrazol concentration of 100 ppm gave the best results on plant height (43.07 cm) and number of leaves (6.24 strands), while paclobutrazol concentration of 200 ppm gave the best results on tuber diameter (23.13 mm) and paclobutrazol concentration of 300 ppm gave the best results on the number of tubers (1.54).

“…Application of new superior variety and planting system could be alternative technology in swamp paddy utilization. According to Saidah et al (2015), application of suitable and adaptive new superior variety is technology component that has significant contribution to paddy productivity improvement. As production component, variety has largest contribution for an increase in paddy production 56,1% (Balitpa, 2007in Rohaeni et al, 2012.…”

Alfayanti A, Wilda M, Taupik R. 2020. Feasibility of swamp paddy farming with new superior varieties and different planting system. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 50-56.Efforts to fulfil the community food demands could be achieved by swamp land optimization. One technology that can be developed on swamp land is utilization of new superior variety and planting system. Economic feasibility is one of considerations for farmers to adopt a technology innovation. The study aimed to determine the combination of the most economically viable new superior variety and planting system to be developed in swamp rice farming. The study was conducted from May-August 2016 in Karang Anyar Village Semidang Alas Maras district, Seluma Regency. There are 7 New Superior Varieties of swamp paddy cultivated; Inpara 1, 2, 3, 6, 7, 8, and Dendang and 1 existing variety as benchmark variety, Cigeulis. The planting system applied were legowo planting system (2:1) with insertion and without insertion. The data used to achieve the research objectives is primary data in the form of farming data to calculate economic benefits and feasibility. Farm profit is calculated using partial analysis whereas economic feasibility is calculated by evaluating the break even point and R/C ratio. The results showed that Inpara 6 with legowo planting system with insertion yield the largest profit Rp 15.096.600,-/ha with R/C ratio of 2.92.
