Since open-field agriculture will face some severe problems in the near future like availability of land and agricultural productivity, an alternative cultivation system, such as soilless cultivation is needed for the sustainability of supply and demand for healthier and safer food. This study aimed to test the effect of vermicompost application method and dosage on growth, yield, and chlorophyll content of water spinach. This experiment used a factorial randomized block design with controls. The first factor was the vermicompost application method, which consisted of three levels, namely solid vermicompost, the combination of solid and liquid vermicompost, liquid vermicompost. The second factor was the vermicompost dosage, which consisted of five levels: 100, 200, 300, 400, and 500g per polybag, compared with control using inorganic fertilizer. The results showed that the vermicompost application method did not significantly affect plant growth and yield. The dosage of 500g in the three different application methods gave significantly higher plant growth compared to control. The fresh weight of water spinach per plant and per polybag in the dosage of 500g showed the highest yield of 13.95g and 122.17g, respectively. The highest chlorophyll content of water spinach was found in solid vermicompost treatment with an application rate of 500g, namely 30.10 µg/ml (chlorophyll A) and 54.79 µg/ml (chlorophyll B). These results indicate that to produce high-quality water spinach in soilless culture systems, it is recommended to use solid vermicompost with an application rate of 500g per polybag.

Sorghum is one of the prospective food crops to be developed in Indonesia. High yielding sorghum variety development is carried out through a series of breeding processes, including agronomic character selection among sorghum plants. The research's objective was to examine the stepwise regression model in selecting agronomic parameters that affect the yield of sorghum grain yield. Evaluation and modeling of the relationship between agronomic parameters and sorghum yield was carried out with two varieties of sorghum, namely Super 1 and Super 2, by using an experimental engineering approach. The estimation model based on information on the phenotypic character of sorghum was implemented using stepwise regression analysis. The results indicated that agronomic parameters affect the yield of sorghum was estimated in three stages, and the final yield equation is Y = -3.413 + 0.033 x2 + 0.561 x3 + 0.006 x5. The variables included in the model are x3 (panicle width), x5 (plant height at harvest), and x2 (panicle length). Correlation and determination coefficient values up to this stage were 0.82 and 0.68, respectively. This indicates that sorghum production can be optimized by the three significant variables: viz, panicle width, plant height at harvest, and panicle length. These results can then be used as a basis for selecting varieties to obtain high yield potential varieties.

Considering that soybeans are a food ingredient, it is necessary to control insect pests that are appropriate and environmentally friendly to increase soybean production, for example, through an intercropping pattern using flowering plants that can attract beneficial insects. This study aimed to increase soybean production by increasing the number of natural enemies planted through an intercropping soybean pattern with Titonia (Tithonia diversifolia). This research was conducted from April - August 2020 at Aras Kabu Village Deli Serdang District; the method used was direct observation to the experimental field of soybean – Titonia intercropping made with 5 Mapping spacing treatments. Harvesting insects using sweep net and for production is counted from soybean pods. The results showed that the soybean-Titonia intercropping had an effect on soybean production, the highest number of seeds was in the treatment of 50 cm spacing between plants (T4) of 57.33, and the highest weight of 100 seeds was in the treatment of 50 cm spacing between plants (T4) treatment of 15.22. The insect orders found in the area of Titonia-soybean intercropping plantations are Hemiptera, Coleoptera, Diptera, Hymenoptera, Lepidoptera, where many predatory insects, parasitoids, and pollinators are found. Judging from the content of secondary metabolites of Titonia, namely alkaloids, tannins, and flavonoids, the results of Titonia plants, including flower, stems, and leaves, can be used to extract pesticides in controlling insect pests.
