Varietas unggul yang cocok dan disukai oleh konsumen dapat dijadikan salah satu alternatif komponen inovasi teknologi untuk dikembangkan dalam mendukung pencapaian target peningkatan produktivitas dan produksi padi. Kegiatan Uji Adaptasi dan preferensi Varietas Unggul Baru Padi (Padjadjaran, Cakrabuana, Munawacita dan Rindang-2). Rancangan yang digunakan Rancangan Acak Kelompok dengan 6 ulangan. Parameter yang diamati tinggi tanaman (30, 60 dan 90 HST), jumlah anakan produktif, panjang malai, jumlah gabah per malai (isi dan hampa) dan hasil (t ha-1 GKG). Data keragaan agronomis dianalisis menggunakan Uji Duncan dilanjutkan dengan uji jarak berganda (DMRT) dengan menggunakan SAS versi 9.0 for windows dan preferensi petani dianalisis menggunakan Uji Friedman. Hasil pengkajian menunjukkan bahwa Varietas unggul baru memberikan keragaman antar varietas dalam karakter agronomi. Varietas Padjadjaran memberikan jumlah anakan produktif, panjang malai, jumlah gabah isi per malai, jumlah gabah hampa per malai relatif lebih baik dengan produktivitas 7,98 t ha-1. Preferensi konsumen menyukai Varietas Padjadjaran dan Cakrabuana sebagai alternatif untuk pergiliran varietas pada agroekosistem dan musim yang sama di lahan sawah.
True seed of shallot (TSS) can be an alternative source of shallot seeds. But the use of TSS in Indonesia is still limited because not many people produce TSS because of high input production. This research aimed to evaluate the technical and economic feasibility of input saving TSS production technology packages. The research was carried out in Ciwidey district, Bandung Regency, West Java, Indonesia from June to October 2016. The research consisted of two factors arranged in a split plot with a randomized block design and eight replications. The main plot was technology packages, namely farmer, recommendation and input saving. The subplot was harvest time, which were 80, 90, and 100 weeks after planting. The observed variables were yield component and yield, soil status, climate data, and farming data. The technical data were analyzed by ANOVA test and continued using the Duncan test at a 95% confidence level. Farming data was analyzed by RC ratio. The results showed that input saving package did not meet seed standards with an RC ratio of 1.07. Savings input on TSS production in Indonesia were only possible by choosing the right location and planting time and must be followed by climate prediction.
One of the efforts to anticipate the impact of climate change on rice is the introduction of new high yielding and early maturing varieties tolerant drought. The aim of this study was to examine the growth performance and potential production of several early maturing and drought tolerant rice varieties in lowland on dry season. The assessment was conducted in Majalengka regency from June to September 2019. Five varieties used were Inpari 39, Cakrabuana, Inpago 11, Rindang 1, and Luhur 1 with through application of Controlled Aerobic Rice based on Organic matter Technology (CARO). Variables observed including plant height and number of productive tillers, number of grains per panicle, percent of empty grains, and also weight of 1,000 grains. The observations results showed that five tested rice varieties showed good adaptation responses to drought stress with average productivity of around 6 to 7 t ha−1. Cakrabuana was potentially to be developed in dry season under drought stress due to its high yield potential and early maturing (85 days after planting). The early maturing and high yielding varieties in the dry season in lowland can be used as an alternative technology to increase the cropping index (CI) and rice production.
Rainfed lowland is a potential physical resource for soybean development to increase the cropping index. The study aimed to optimize the rainfed paddy fields by introducing a package which has several recommended technologies in a limited amount of water condition. The study was conducted in Sanca Village, Gantar District, Indramayu Regency from July to September 2019. The treatment was a recommended technologies package in soybean farming. The observed variables were plant height and number of branches in three growth phases, namely vegetative phase, flowering phase and maturing phase. The yield components were also observed. The collected data were analyzed by using t-test with technical cultivation of farmers’ ways as a comparison. The results showed that the recommended technology package for soybean cultivation in the dry season produced higher soybean productivity (1.25 t ha−1). Cultivation of soybeans in the dry season in rainfed lowland areas must pay attention to the suitability of varieties and availability of water sources in an effort to achieve optimal production.
