The use of biochar and biocompost can be one solution to the addition of organic matter in soybean cultivation. This study aims to obtain a good description of the role of biochar and biocompost on growth, yield, and N uptake. The results of the study show that: (1) Application of biochar in soybean plants affects plant height, number of vacuous pods, number of pods containing, weight 100 seeds, and N uptake compared with no biochar application.(2) Biocompost application has a significant effect on the height of soybean plants aged 2,3, 4 and 5 weeks after planting, dry weight, seed weight, number of vacuous pods and number of pods filled. (3) Biocompost with a liqui d form dose of 2.5 grams/plant significantly affected the number of filled pods and the number of soybean pods. (4) Liquid biocompost dose of 5 grams/plant affects dry weight and plant height of 2 MST. While the 7.5 gram/plant liquid biocompost has an effect on the weight of soybean seed plants.

Biourine is a liquid fertilizer that contains complete elements, namely nitrogen, phosphorus, and potassium in small amounts as well as zinc, iron, manganese, and copper. Biourine can provide an increase in plant yields that is almost the same as plant fertilizers, besides that it can control Fusarium wilt disease. This study aims to determine the effect of Trichoderma biourin application on plant growth, Fusarium wilt disease and onion yield. The research was conducted using an experimental method in Senteluk Village, Batu Layar District, West Lombok Regency, West Nusa Tenggara using a Split Plot Design consisting of 2 factors. As the main plot, the shallot varieties consist of three levels, namely Bali Karet, Ampenan and Keta Monca, while as a sub-plot, the Trichoderma biourin application method consists of four levels, namely: without biourine, spraying the soil surface, spraying seed tubers, and spraying on plants 21 days after planting. The treatment was a combination of shallot varieties and Trichoderma biourine application method, each of which was repeated three times, so there were 36 experimental units. The results showed that: (a) The application of liquid biourine by spraying the soil surface, spraying seed tubers and spraying on plants 21 days after planting could increase the growth and yield of shallot bulbs. (b) The Bali Karet shallots varieties are more resistant to Fusarium wilt disease when compared to Ampenan and Keta Monca varieties.

Research on the application of silicate fertilizer and manure to growth, brix level, and yield of sorghum (Sorghum bicolor (L.) Moench) was investigated to find ways to increase sorghum productivity in the dry land. The research method used was an experimental method that was set in a randomized block design consisting of 9 treatments namely control (Si0P0), without silicate and manure, 5 tones/ha (Si0P5), without silicate and manure 10 tones/ha (Si0P10), silicate 100 kg/ha and without manure (Si100P0), silicate 100 kg/ha and manure 5 tones/ha (Si100P5), silicate 100 kg/ha and manure 10 tones/ha (Si100P10), silicate 200 kg/ha and without manure (Si200P0), silicate 200 kg/ha and manure 5 tones/ha (Si200P5), and silicate 200 kg/ha and manure 10 tones/ha (Si200P10). Each treatment was replicated 3 times and the size of the plot was 6x6 m2. The results indicated that the application of silicate fertilizer and manure could significantly increase yield and brix levels. Application of silicate fertilizer of 200 kg/ha and manure 5 tonnes/ha gave higher results for the production of sorghum was 6056 kg/ha. However, the growth of sorghum was not affected significantly to the growth of sorghum plants.

Elephant food yam (Amorphophallus muelleri Blume) is an important tuber plant that is grown in most of the tropical countries including Indonesia and is a very profitable export commodity. Soil nutrients availability is one of the most important factors that determine the production of elephant food yam plants. However, there is no single nutrient source, either from inorganic fertilizers or organic fertilizers or biological fertilizers, which is able to meet all the nutrient needs of the plants grown. Therefore, integrated nutrient management (INM) of elephant food yam plants seems to be a way out to maintain sustainable production and increase profitability. This paper reviews the results of research on various issues of INM-based production management for elephant food yam plants and analyzes the extent of research on the use of INM both in Indonesia and abroad. The benefits of integrated nutrient management are well documented for vegetable crops. However, it is still very little available for elephant food yam plants, especially in Indonesia. Integrated nutrient management (INM) is a very important technological innovation to be applied to elephant food yam cultivation. Elephant food yam is a high nutrient consumeplant, so a wise and precise combination of inorganic and organic fertilizers as well as bio-fertilizer will result in sustainable and sinergistic use of soil nutrients of elephant foot yams. Therefore, recommendations for research need for INM of elephant food yam should be carried out in order to increase the production of it in a sustainable manner.

Pandemi Covid 19 yang terjadi di seluruh dunia berdampak pada berbagai aspek kehidupan yang sering dibutuhkan oleh masyarakat dunia, salah satunya adalah ketahanan pangan yang terjadi di Indonesia yang menjadi suatu hal yang sangat di antisipasi oleh warga, khusus nya yang berada disekitaran daerah atau lahan yang relatif kering yang membuat warga yang bertempat tinggal di daerah tersebut kesusahan untuk mencukupi kebutuhan pokok nya, seperti sayuran dan juga buah buahan yang termasuk dalam konsumsi pokok bagi warga, upaya untuk mengatasi hal tersebut yaitu dengan cara berbagi ilmu beserta pengalaman dengan para warga seperti metode penanaman dan juga cara ataupun terobosan baru lainya, salah satunya adalah metode penanaman hidroponik dengan menggunakan styrofoam sebagai media untuk penanaman tumbuhan sayuran dan lain lain, metode hidroponik ini sebenarnya banyak macam nya hanya saja dengan menggunakan media styrofoam ini diharapkan hal ini tidak banyak menguras biaya dan tentunya mudah untuk dipahami oleh warga ataupun masyarakat yang masih awam terhadap metode ini, terlebih lagi mulai dari bahan yang digunakan relatif mudah untuk didapatkan, dan juga hal ini bertujuan untuk tata cara menjadi peluang usaha baru bagi para warga dimana di masa pandemi seperti ini hampir sebagian pekerja mengalami PHK dan masyarakat lainya kehilangan pekerjaan sehari harinya.
