Abstract

Improvements in cocoa cultivation techniques need to be done by adding goat manure as a mixture of planting media to improve the physical properties of the soil in order to make it easier for roots to develop. This objective of this study was to determine concentration of mycorrhizae, the best growing media for cocoa seedlings, and interaction on the growth of cocoa seedlings. The method used was randomized block design with two factor. The first factor was the inoculation of mycorrhizae consisting of four levels: without inoculation of mycorrhizae 10 g/plant, 20 g/plant, and 30 g/plant. The second factor was the growing media with three levels of growing media: top soil, top soil + goat manure compost (1:1), and top soil + goat manure compost (1:2). The results showed that the growing media had a significant effect on the height and volume of plant roots. Growing media of top soil produced the best average seedling by 38.06 cm and root volume by 4.39 cm3. The interaction of giving mycorrhizae with growing media had a significant effect on root volume with the best treatment 10 g/plant mycorrhizae and top soil by 5.67 cm3. The results analysis of root infection by arbuscular mycorrhizal fungi showed the highest infection in the 20 g/plant mycorrhizae and top soil by 80%. Application of mycorrhizae with growing media can increase cocoa yield and growth. Planting media mycorrhizae infected to soil can affect cocoa seedling.

Abstract

In increasing the production and quality of rice plants, it is essential to pay attention to proper nutrient management. One of the most important nutrients in increasing rice production and quality is magnesium, tested with deficiency and toxicity treatments in subsoil soils. This study used a factorial randomized block design with two factors where each treatment was repeated three times. First factor included Nutrient toxicity Mg, T0 = 0 (control), T1 = 2.2 g/polybag, T2 = 4.4 g/polybag, T3 = 8.8 g/polybag. Second factor included Mg nutrient deficiency D0 = 0 (control), D1 = 0.56 g/polybag, D2 = 0.28 g/polybag, and D3 = 0.14 g/polybag. The results showed that the deficiency treatment significantly affected plant height 5-6 weeks after fertilization and leaf chlorophyll 9 WSP. In contrast, the toxicity treatment significantly affected Total Chlorophyll 4 MSP and 1000 grain weight, where the D2 and T2 treatments showed the highest data. This study explained that the D2 and T2 treatments showed good plant responses. The red sigambiri variety was quite tolerant of magnesium deficiency and toxicity treatments.
