Double Production in Groundnut with Phosphatic Biofertilizers

Groundnut (Arachis hypogea L., 2n=20) is nitrogen fixing pulse crop, belong to Leguminocae family. The present study conducted on production of groundnut with phosphatic biofertilizers. The experiment was conducted at Madhav village and Sattasar village in May, 2015. The mycorrhiza solid powder dissolved with molasses + water to form organic product. The seed poured in the formulated organic product for 24 hrs. Later, the seed was placed in the prepared land. The seed emerged from the soil in 7-10 days and the flower appeared in the plant within 35 days after sowing. The healthy nodule was formed in the root organ with application mycorrhiza solid powder. The application of mycorrhiza solid powder progresses morphological growth, yield, soil property and soil biology. Keywords: groundnut, production, biofertilizer, nodule formation

Efficiency analysis of chilli pepper farming with proliga technology application in Batam City

The existing cultivation pattern of chilli pepper in Riau Islands is unable to fulfilled all market demands. Dissemination of double production (Produksi Lipat Ganda or Proliga) technology was an effort to increase chilli pepper production in Riau Islands. This study aims to analyze the efficiency of chilli pepper farming with Proliga technology application. This research was conducted in Mei 2019 until April 2020 at Maju Mandiri Farmer Group, Setokok Village, Bulang District, Batam City. The primary data obtained from interviews, and the secondary data obtained from related agencies. Data analysis was carried out by calculating costs, revenues, income, and farming efficiency. Based on analysis results, it can be concluded that chilli pepper farming with Proliga technology generates an income of IDR 699,000,000, and the cost incurred in one planting season (12 months) reached IDR 213,193,500. Therefore, the income obtained by farmers is IDR 485,806,500 / hectare. This chilli pepper farming is considered efficient and profitable for farmers, as indicated by the R/C ratio value of 3.27.
