Peranan Poliembrioni Terhadap Produksi Benih Pada Tanaman Jeruk Siam (Citrus nobilis L.)

This study aims to determine the growth of polyembryonic seeds in Siamese oranges and to study the growth of seedlings from polyembryonic seeds which will be used as good seeds in overcoming the problem of availability of Siamese orange seeds. The research was carried out from May to October 2022 at the Green House of the Faculty of Agriculture, Sam Ratulangi University and Eris Village, Eris District. The research method used a randomized block design (RBD) with 5 treatments repeated 4 times and found a total of 20 treatments, namely Z11, Z12, Z13, Z14, P21, P22, P23, P24, P31, P32, P33, P34, B21, B22, B23 , B24, B31, B32, B33 and B34. Data analysis used ANOVA analysis (analysis of variance). If it has no effect, then proceed with the BNT test at the 5% test level. The results showed that the growth of Siamese orange sprouts resulted in the growth of embryos up to 6 intact in one seed. Polyembryony, the ability to germinate seeds above 80.00% is one of the conditions for seeds to be recommended for seed sources 20.95%

Interaction of Municipal Garbage Waste and Local Microorganisms (LOM) of Banana Weevil on Soybean Yield

Soybean is the third main food commodity after rice and corn because soybean is a source of protein for Indonesian people. The high use of inorganic fertilizers causes fertile land resources to decrease. The need for soybeans increases with the increase in population. Reduced availability of soybean supply so efforts are needed to increase soybean production. Utilization of municipal waste as an effort to reduce the use of inorganic fertilizers. The study aimed to determine the effect of the interaction between municipal solid waste and local microorganisms on banana weevils on soybean yields. The research was conducted in Tember Village Tompaso District Minahasa Regency from May to October 2021. The study used a completely randomized factorial design. The treatment consists of, Factor I (A) = city waste compost. A0=without municipal waste compost, A1=10 tonnes/ha municipal waste compost, A2=20 tonnes/ha municipal waste compost. Factor II (B) = dosage of banana weevil local microorganisms. B0=without local microorganisms; B1= 50 ml of banana weevil local microorganisms/1 liter of water; B2=100 ml of banana weevil local microorganisms/1 liter of water, B3= 150 ml of banana weevil local microorganisms/1 liter of water. Each treatment was repeated three times to obtain 36 trial pots. The results showed that the concentration of 150 ml of local microorganisms (LOM) on banana weevil at 20 tonnes/ha of municipal waste compost increased the number of soybean seeds by 532 and the weight of soybean seeds per plant was 107 grams
