Hybrid maize seed production requires specific cultivation and management techniques that differ from commercial maize production, particularly in regulating the ratio of male and female plants to ensure effective cross-pollination and genetic purity. This study aimed to describe the implementation of hybrid maize seed production of Pioner 8050 (Corteva) using a 5:1 female-to-male planting ratio in Kanigoro Village, Kanigoro District, Blitar Regency, Indonesia. The research employed a descriptive field-study approach conducted on approximately 100–120 ha of seed production land managed by farmer groups under a partnership scheme with a seed company. Data were collected through direct field observations and structured interviews focusing on planting ratio arrangement, detasseling practices, fertilization, pest and disease management, irrigation systems, and partnership mechanisms.

The results showed that the application of a 5:1 planting ratio effectively optimized land use while ensuring adequate pollen availability for cross-pollination. Zero tillage practices, balanced fertilization using urea and NPK, integrated pest and disease management, and controlled detasseling contributed to maintaining genetic purity and seed quality. The partnership system facilitated farmers’ access to production inputs, technical guidance, and assured market absorption. Productivity reached 6–7 tons ha⁻¹ of fresh ears, with harvested kernels exhibiting appropriate physiological maturity, moisture content, and high viability.

Overall, the hybrid maize seed production system implemented in Kanigoro Village demonstrates a technically effective and institutionally supported model that can be replicated in other regions to enhance sustainable hybrid maize seed development and strengthen national seed supply systems.

Lengkong Subdistrict, particularly Ketandan,Ngringin, and Jati Villages, is the largest tobacco production centre in Nganjuk Regency. Despite high tobacco production, farmers' welfare has not beenfully achieved due to various factors such as processing and marketingthat are not yet optimal. This study aims to analyse the influence of income, education, and land area on the welfare of tobacco farmers in Lengkong SubdistrictLengkong. A total of 50 respondents were selected using random sampling techniques, anddata was collected through a Google Form questionnaire. Data analysis was performedusing SPSS 26.0. The results showed that the income variablesignificantly influenced farmers' welfare,as indicated by a t-value of 2.429 and a significance level of 0.022. Meanwhile,the variables of education (t count 1.702) and land area (t count 0.503) did nothave a significant effect because the significance value was greater than 0.05. The simultaneous test showed that the three variables together had an effecton farmer welfare with a calculated F value of 11.070, which was greaterthan the table F. Among all the variables, income had the highest Standardised Coefficients Beta value, making it the most dominant factorinfluencing the welfare of tobacco farmers in Lengkong Subdistrict

This study aimed to determine the effectiveness of residual snow pea growing media combined with manure and mycorrhizae on the growth of bok choy without additional fertilization, supporting sustainable agriculture.The research method used was a completely randomized design (CRD) with 7 treatments and 3 replications. The treatments were as follows: P0 = 100% soil, A1D1 = 4 kg soil + 1 kg cow manure + 15 grams of mycorrhizal fertilizer. A1D2 = 3 kg soil + 2 kg cow manure + 10 grams of mycorrhizal fertilizer. A1D3 = 2 kg soil + 3 kg cow manure + 5 grams of mycorrhizal fertilizer. A2D3 = 4 kg soil + 1 kg goat manure + 15 grams of mycorrhizal fertilizer. A2D2 = 3 kg soil + 2 kg goat manure + 10 grams of mycorrhizal fertilizer. A2D3 = 2 kg soil + 3 kg cow manure + 5 grams of mycorrhizal fertilizer. Observed parameters included plant height, leaf number, fresh weight, and mycorrhizal spore density.The results showed that the combination of 1 kg of goat manure and 15 grams of mycorrhizal fertilizer (A2D1) with residual pea growing media resulted in the best growth for bok choy. In the A2D1 treatment, plant height reached 23.6 cm, with 12 leaves, and a fresh weight of 154.3 grams per plant. Meanwhile, the control treatment (P0) and the 154.3 grams of residual pea growing media alone produced the lowest growth rates.

Optimalisasi Sektor Pertanian di Kabupaten Jombang untuk Perkembangan Ekonomi Daerah

The agricultural sector in Jombang Regency serves as the backbone of the regional economy, contributing significantly to the Gross Regional Domestic Product (GRDP), accounting for approximately 27.3%, valued at Rp 21.4 trillion (BPS, 2024). Nevertheless, the sector's direct contribution to Local Own-source Revenue (PAD/Pendapatan Asli Daerah) remains relatively low because most agricultural products are marketed as raw commodities with limited value addition. This research aims to analyze the agricultural sector's contribution to GRDP and PAD, identify the existing potential and constraints, and formulate optimal strategies to enhance the sector's role in local economic development. The research employed a mixed-methods approach, utilizing quantitative analysis through the Location Quotient (LQ) to identify base commodities, and qualitative analysis via in-depth interviews with key stakeholders, subsequently analyzed using the SWOT matrix. The findings indicate that the main base commodities in Jombang include rice (padi), sugarcane (tebu), and horticulture, all possessing high comparative advantage. This significant potential is supported by diverse agro-climatic conditions and the availability of productive human resources, especially young farmers. However, several structural constraints still impede optimization, including limited access to capital/financing, uneven irrigation infrastructure, weak farmer institutional capacity, and limited product quality certification. The recommended strategies include: (1) developing downstreaming (hilirisasi) of agricultural products to increase value addition; (2) strengthening farmer institutions through professional cooperatives; (3) implementing modern agricultural innovation and technology; and (4) establishing an integrated agropolitan area that connects with MSMEs, tourism, and export markets. Implementation of these strategies is projected to boost PAD by approximately Rp 80–100 billion annually, create new job opportunities, and strengthen regional fiscal independence. Thus, reinforcing the agricultural sector in Jombang Regency not only implies improving farmer welfare but also serves as a strategic instrument for the local government in building a competitive, inclusive, and sustainable local economy.

This study aims to study the effectiveness of liquid organic fertilizer (POC) made from goat urine on the growth and yield of purple eggplant (Solanum melongena L.). The study was conducted in Keras Village, Diwek District, Jombang Regency, using a Randomized Block Design (RBD) with six treatments, namely P0 (control), P1 (NPK 4 g/plant), P2 (POC 100 ml/L), P3 (POC 150 ml/L), P4 (POC 200 ml/L), and P5 (POC 250 ml/L). Each treatment was repeated four times. The analysis of variance showed that the administration of goat urine POC significantly affected all observed parameters, including plant height, number of leaves, number of flowers, number of fruits, and fruit weight. The optimum dose was 250 ml/L of goat urine liquid organic fertilizer.
