The treatments studied were P0 : 0 control (without compost), P1 : 10 tonnes/ha of goat manure compost (6 kg/plot). P2: 20 tons/ha of goat manure compost (12 kg / plot), P3: 30 tons/ha of goat manure compost (18 kg / plot) and P4: 40 tons/ha of goat manure compost (24 kg / plot). The parameters observed were plant height (cm), number of leaves (strands), length of cobs without husks (cm), diameter of cobs without husks (mm), ear weight per cob without husks (g) and yield per harvest plot with husks (kg). Based on the results of the research that has been carried out, it can be concluded that giving a dose of goat manure compost has a very good effect on the growth and yield of baby corn plants. Treatment P2 (20 tons/ha) produced the highest plant height of 102.40 cm, the highest number of leaves was 9.68 at 28 days after planting, produced the highest cob length without husks per plant of 15.60 cm, the highest diameter of cobs without husks per plant 18 .70 mm, the highest cob weight per cob without husks was 49.52 g and the highest yield per husked plot was 2.36 kg.

Tidal land of overflow type D has the potential to be planted with vegetables, including cow peas, despite the infertile condition of the land.  The use of mulch (including sawdust mulch and black and silver plastic mulch) is one of the crop cultivation techniques that can be used to increase the yield of cowpeas. The purpose of this study was to determine the most optimal mulch for increasing cow peas production on tidal land of overflow type D. The research was conducted on an area owned by PT Perdangan Indonesia located at Jalan H.M. Asyik Aqil, RT 49, RW 17, Sukajadi Village, Talang Kelapa District, Banyuasin Regency, South Sumatra Province, from Oktober 2023 to January 2024.  The method used was a field experiment using a non-factorial Randomized Group Design with 3 treatments repeated 9 times.  The treatments consisted of no mulch, sawdust mulch, and silver black plastic mulch.  The best cowpea production was obtained in the application of black silver plastic mulch, which was 6.19 kg/plot, or equivalent to 16.51 tons/ha. The date indicates that there wa an increase of 27,60 % when the much was not applicated in the analysis.

This study aims to review the response of green eggplant plants (Solanum melongena L.) due to the application of liquid organic fertilizer (POC) at various planting distances. This research has been carried out in the Experimental Garden Land of the Faculty of Agriculture, Tridinanti University located in Pulau Semambu Village, North Indralaya District, Ogan Ilir Regency, South Sumatra Province. The study has been conducted from November 2023 to January 2024. The method design used was an experimental method using Group Random Design (RBD) with 6 (six) treatments and 4 (four) repeats. The number of plants studied in the experimental unit is 3 (three) sample plants. The treatment studied was J1 = planting distance 70 cm x 40 cm without POC, J2 = planting distance 70 cm x 60 cm without POC, J3 = planting distance 70 cm x 80 cm without POC, J4 = planting distance 70 cm x 40 cm using POC "Growing" 4 ml / liter water, J5 = planting distance 70 cm x 60 cm using POC "Growing" 4 ml / liter water, and J6 = planting distance 70 cm x 80 cm using POC "Growing" 4 ml/liter of water. The parameters observed are plant height (cm), number of branches (branches), age of flowering plants 60% (days), number of fruits per plant (fruit), fruit weight per plant (kg) and fruit weight per plot (kg).  Based on the results of the study, it can be concluded that the application of liquid organic fertilizer with various planting distances has a good effect on the growth and yield of green eggplant plants (Solanum melongena L.). The application of liquid organic fertilizer (4 ml / liter of water) with a plant distance of 70 cm x 60 cm (J5) produce plant height 43.41cm, number of branches 4.59 branches, age of flowering plants 42.25 days, number of fruits per plant 19.60 pieces, fruit weight per plant 3.07 kg per plant, and fruit weight per plot 27.79 kg.
