“…In Indonesia, the development of superior rice varieties through cross-breeding began in the 1900s using germplasm originating from various sources. Until 1965, rice breeding was directed at establishing varieties suitable for multiple land conditions, including land with medium and low fertility levels [97]. The most significant increase in production occurred from the 1970s to the 1980s with the introduction of new high-yielding varieties that were more responsive to fertilizers and matured early, for example, IR36, Cisadane, IR64, and IR66, with a growth rate of 3.3% each year [98].…”

Coastal acid-sulfate soils are crucial for producing crops and thus, for food security. However, over time, these soil resources experience degradation, leading to higher agro-input, lower yields, and environmental hazards that finally threaten food security. The optimal use of this fragile resource is only attained by implementing vigorous integrated water–soil–crop management technologies amid the climate change impact. This study aimed to review the distribution, properties, use, and management of acid-sulfate soils in Kalimantan, Indonesia. Acid-sulfate soils cover about 3.5 Mha of the coastal area in Kalimantan and have high acidity, high-risk iron and aluminum toxicity, and low fertility, requiring precise water management, amelioration and fertilizer application, crop variety selection, and rice cultivation technologies. Lime, biochar, organic fertilizer, compost, ash, and fly ash are ameliorants that raise pH, reduce iron and aluminum toxicity, and improve crop yield. Rice cultivation has developed from traditional to modern but needs re-designing to fit local conditions. Depending on the soil nutrient status, rice cultivation requires 80–200 kg ha−1 of urea, 50–150 kg ha−1 of SP36, 50–150 kg ha−1 of KCl, and 125–400 kg ha−1 of NPK compound fertilizer, but is affected by CH4 and CO2 emissions. Good water management impacts the effective implementation of amelioration and fertilizer application technologies. The remaining challenges and future directions for water management, amelioration, fertilizer application, crop varieties, cultivation techniques, land use optimization, climate change adaptation and mitigation, technology adoption and implementation, and resource conservation are outlined. Acid-sulfate soils remain a resource capital that supports food security regionally and nationally in Indonesia.

“…New high-yielding varieties (VUB) are the main technological component in increasing plant productivity [20]. And that the introduction of high-yielding high-yielding varieties began already before the era of the green revolution [21]. Likewise for the use of new high-yielding varieties in corn, where the advantages of corn VUB will be felt by producers and consumers when quality seeds from these high-yielding varieties are available and widely grown.…”

North Minahasa Regency is a corn development area in North Sulawesi, but its production is still low. The aim of the research is to obtain data on corn production systems and their development policies. Survey and FGD data collection techniques. Implementation February - March 2020. Analysis of quantitative data using multiple linear regression. The results showed that farmers are starting to use new superior varieties that have higher potential than local varieties, but the use of cultivation technology is still in accordance with farmers’ habits. The results of the coefficient test, the results of the t test or the sig probability value show that the area of land and labor has a calculated t value of 2.532 and 2.221; bigger than t table (2.064). This means that the variable land area and labor have a significant effect on corn production at α 5%. The potential for the development of this commodity is quite promising, but it is necessary to increase production referring to cultivation technology and product diversification.

Penggunaan benih padi sawah irigasi di Indonesia didominasi oleh varietas padi unggul yang sudah lama dilepas. Fenomena ini juga terjadi di sentra-sentra produksi padi di Kabupaten Bengkulu Selatan. Penelitian ini bertujuan untuk mengetahui tingkat adopsi benih padi unggul baru pada sentra produksi Kabupaten Bengkulu Selatan. Pengumpulan data melalui survei dilakukan pada bulan Oktober hingga Desember 2022 dengan melibatkan 87 petani dari 81 kelompok tani di sentra produksi padi sawah irigasi di tiga kecamatan Bengkulu Selatan, yakni Seginim, Air Nipis, dan Kedurang. Wawancara juga dilakukan dengan penyuluh pertanian untuk konfirmasi data survei. Data meliputi karakteristik petani, penggunaan varietas padi, sumber benih, dan masalah adopsi varietas unggul baru. Data dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa empat varietas padi unggul lama yaitu Cigeulis, Ciherang, Mekongga, dan IR64 masih banyak digunakan petani masing-masing sebesar 31,61%, 31,03%, 27,01%, dan 6,32%. Tingkat adopsi varietas unggul baru oleh petani hanya mencapai 4,00%. Rendahnya adopsi tersebut karena sebagian besar petani masih menggunakan benih hasil panen sebelumnya yang berasal dari lahan sendiri, tetangga, atau keluarga sebesar 52,87%. Sementara itu, hanya 25,29% petani yang menggunakan benih dari bantuan pemerintah, dan sisanya diperoleh dengan membeli benih dari kios pertanian (17,24%) atau penangkar benih (4,60%). Oleh karena itu, pemerintah perlu memperkenalkan varietas unggul baru padi melalui program dukungan benih bagi petani untuk mendorong adopsi varietas unggul baru.
