Abstract

Downy mildew control with synthetic fungicides adversely affects it. The use of biological agents is an alternative because it is safer and environmentally friendly. The purpose of the study was to determine the effect of seed treatment using biological agents on corn seed viability, downy mildew and plant growth. Group Randomized Design (RAK) research method with three treatments and repeated 9 times. The treatment is K (without treatment), B (Bacillus subtilis and B. polymixa) and T (Trichoderma hamatum). B and T treatments were able to increase the viability of corn seeds as well as the length of roots and headers. Treatment B was more able to suppress the incidence and intensity of downy mildew compared to control and T. Treatment of the two biological agents was able to increase the number of leaves of corn plants and was not able to increase plant height, stem diameter and plant root weight.

Abstract

Ciplukan (Physalis sp.) is useful for treating disease problems. The application of plant spacing in cultivation is necessary to reduce competition. The aim of the research was to determine the effect of fertilization and planting distance on ciplukan plants. Ciplukan has strong endurance so it can live in extreme areas such as acid soil. Ciplukan cultivation on acidic land requires intensification of treatment and plant spacing to increase yields. The research used a split plot design method with the use of fertilizer treatment factors, namely without fertilizer (P1), goat manure + mycorrhiza (P2), goat manure + phosphorus (P3) and NPK (P4) and a planting distance of 40x50 cm (J1) and 30x50 cm (J2), and all treatments were repeated 4 times. The experimental results were analyzed using analysis of variance at the 5% level and the Duncan Multiple Range Test. The results of the research show that fertilization and plant spacing can simultaneously increase plant height, number of leaves, fruit weight, number of fruit, wet and dry weight of ciplukan plants. The best treatment combination in P4J1.
