The productivity of red ginger in Indonesia has decreased by 9,174 tons compared to 2017. The decrease is due to the very limited area of red ginger production, the method of red ginger cultivation, which is still very conventional, and the low amount of organic matter in the soil. This study examines the effect of planting media composition on the growth and production of red ginger. The study used a Completely Randomized Block Design (RCBD) with six treatments, namely control (soil without manure), cow manure: green manure: soil (1:1:1), P2 = goat manure: green manure: soil (1:1:1), green manure: soil (1:2), cow manure: soil (1:2), and goat manure: soil (1:2) and repeated four times. Composition media of goat manure: green fertilizer: soil with a ratio of 1:1:1 could increase the growth of red ginger in variable plant height, number of leaves in the clump, leaf area, and the weight of fresh stover with a yield of 52.7 cm; 10,75; 148,5; 2952.59 cm2; and 307.33 g. Composition of green fertilizer media: soil with a ratio of 1:2 could increase the weight of dry stover with a value of 39.32 g, and red ginger production includes fresh weight of rhizomes 111.32 g, storage weight of rhizomes 107.87 g, and rhizome volume 124.12 cm3.

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.

Modifying cultivation techniques potentially enhances mustard physical qualities to attain the demanded marketable value. The reputation of organic mustard propels farmers to implement modified cultivation techniques to improve harvest quality further. Planting space is one of the modifiable technical cultivations to achieve sustainable crop production. This research used soil planting media from acid dry land to optimize agricultural land use and cow manure as primary fertilizer to implement organic farming. This research objective is to figure the effect of different planting spaces on the growth and productivity of mustard greens that applied organic cultivation method. The preliminary arrangement of the research was a single-factor randomized block design. The factors were studied with different planting spaces: control without planting spaces, planting space of 20x20, 25x25, 30x30, 35x35, and 40x40 cm2. The outcomes revealed that the mean values of mustard green plant height (13.38 cm) and the number of leaves (9 strands) had significant differences to the control treatment (10 cm plant height and seven strands number of leaf). The results showed that the optimum planting space of organic mustard cultivation was 40x40 cm2 which achieved significantly higher plant height and the number of leaves than the control without planting spaces. This research's planting space of 40x40 cm2 is appropriately suitable for monocropping systems in acid dry land. It can alter plant population and distribute environmental resources for sustaining crop growth and production.
