Unfortunately, the soil has low chemical fertility and is characterized by a small part of macronutrients. To support the maize growth in inceptisol, nitrogen, phosphorus, and potassium are the primary required nutrients. Hence, applying inorganic fertilizer is one of the strategies to solve this issue. This study was conducted at Sei Bingai District, Langkat Regency, from July to November 2021. This study aims to analyze the effect of phosphorus and potassium on the maize growth and production of inceptisol. This study was arranged by Non-Factorial Randomize Complete Block Design with seven treatments and four replications. These treatments are consist of: PK 0 (control), PK 1 (standard fertilization), PK 2 (50 % PK plus dose + 75 % standard fertilization), PK 3 (100 % PK plus dose + 75 % standard fertilization), PK 4 (150 % PK plus dose + 75% standard fertilization), PK 5 (100 % PK plus dose + 50 % standard fertiliz...

Pest control carried out by farmers using pesticides is feared to threaten the sustainability of soybean production in Indonesia. This study aimed to identify the effect of different pest management systems and various soybean varieties on pest population dynamics, abundance and diversity of natural enemies, plant damage, and soybean production. A split plot design with three replications was applied, where the main plot was pest management systems i.e. (1) control (which received neither chemicals nor integrated pest management), (2) chemical control, and (3) integrated pest management, and the sub-plot was soybean varieties i.e. (1) Anjasmoro, (2) Demas 1, and (3) Dering 1. Results indicated that variety affects pest diversity and abundance, however, it affected leaf damage, pod damage, and production. The pest management systems influenced the diversity and abundance of pests and natural enemies, plant damage...

Inpari IR Nutri Zinc sebagai produk biofortifikasi, menjadi salah satu komponen dalam program prioritas nasional untuk mengatasi stunting di Indonesia. Varietas Inpari IR Nutri Zinc sangat berpotensi untuk dikembangkan pada berbagai agroekosistem, bila didukung oleh komponen teknologi yang sesuai agar pertumbuhan dan hasilnya maksimal. Sasaran yang tepat untuk pengembangan Inpari IR Nutri Zinc adalah daerah-daerah dengan tingkat kemiskinan tinggi, yaitu golongan masyarakat yang mengandalkan beras sebagai bahan pangan pokok sekaligus sumber mineral yang dapat dikonsumsi setiap hari. Peluang pengembangan varietas ini menghadapi berbagai tantangan, antara lain preferensi petani dan permodalan yang masih rendah, serta teknologi pengolahan hasil untuk mendukung produk olahan berasnya bernilai jual ti...

Unfortunately, its availability in North Sumatera Province is difficult to find. One of the measures to solve the scarcity is by maintaining the existence of the Seed Resources Management Unit (SRMU) and Seed Grower. This study has specific objectives, to inform the total potential production, the kind of varieties and the distribution of certified rice seed from SRMU and Seed Grower and to estimate the opportunity to enhance the certified rice seed sustainability. A descriptive method was used for this study by using observation and comparative analysis techniques. The results show that there are 4,693.5 ton of certified rice seed generated from SRMU and Seed Grower, which is Inpari 32, Mekongga and Inpari 42 are the dominated varieties. This study also found that the majority of certified rice seeds were distributed to Deli Serdang, Serdang Bedagai and Labuhan Batu Regency. ...
