This research used a Randomized Block Design (RAK) with 5 (five) treatments and 5 (five) replications, each replication consisted of 20 plants, so the number of plants studied was 500 plants. The number of samples observed in each experimental unit was 3 (three) plants. The treatments in this research were as follows: P0 = No NPK fertilizer, P1 = 100 kg/ha NPK fertilizer, equivalent to 60 g/plot, P2 = 200 kg/ha NPK fertilizer, equivalent to 120 g/plot, P3 = 300 kg/ha NPK fertilizer, equivalent to 180 g/plot, P4 = 400 kg/ha of NPK fertilizer, equivalent to 240 g/plot. Parameters observed in this study were plants height, number of branches, flowering age, number of fruit per plants, harvest age, fruit diameter, fruit weight per plants and fruit weight per plot. Applying NPK fertilizer has a good influence on plant growth and yield of Provita F1 eggplant. Applying of NPK fertilizer at a dose of 120 g/plot (P2) produces a plant height of 48.8 cm, number of branches 7.73, flowering age 30.47 dap, number of fruit per plant 3.49, harvest age 65 dap, fruit diameter 43.01 mm, fruit weight per plant 2.11 kg and fruit weight per plot 2.79 kg.

This research aims to determine the growth and yield response of waxy corn (Zea mays ceratina) plants due to the application of various doses of swallow manure fertilizer.  This research was carried out in Sri Karang Rejo Village, Lalan District, Musi Banyuasin Regency from October 2022 to December 2022.  The research design used was an experimental method using a Randomized Block Design (RAK) with 4 treatments and 6 replications, each plot consisting of 50 plants, so the number of plants examined was 1200 plants.  The number of samples in the experimental unit was 3 plants.  The treatments studied were P0 = no fertilizer, P1 = 10 tonnes/ha equivalent to 10 kg/plot, P2 = 15 tonnes/ha equivalent to 15 kg/plot, P3 = 20 tonnes per/ha equivalent to 20 kg/plot.  The variables observed were plant height (cm), number of leaves (strands), length of cobs without husks (cm), diameter of cobs without husks (cm), number of cobs per plant (cobs), weight of cobs with husks per plant (g), weight husked cobs per plot (g). The response to the growth and yield of waxy corn (Zea mays ceratina) plants due to the application of various doses of swallow dung fertilizer resulted in a good response to the growth and yield of waxy corn plants (Zea mays ceratina) due to the application of various doses of swallow dung fertilizer. Providing 20 tons of swiftlet manure per ha can produce a plant height of 141.85 cm, ear length of 12.1 cm, ear diameter of 3.7 cm, ear weight per plant of 133.7 g, and ear weight per plot of 5,825 g.

The research aims to determine and understand the influence of S.R.I and conventional rice cultivation on the yield and production of lowland rice from the Black, Red and Ciherang varieties. This research was carried out in the Greenhouse of the Faculty of Agriculture, UTP. The research was carried out from February to August 2019. The experiment was structured using a completely randomized design (CRD) with a two-factor factorial pattern. The first factor is rice cultivation which consists of two treatments, namely conventional cultivation (K) and S.R.I cultivation (S) and the second factor is Variety (V) with three treatments, namely the Black variety (H), the Red variety (M), the Ciherang variety (C ), with 3 replications and 18 treatments. The research results reveal that S.R.I cultivation can increase production results between 21 - 50% when compared to conventional. Then the SRI system can increase the number of productive tillers per hill by 50.12%, the weight of grain per hill by 22.30%, the weight of grain per ha by 9.3 tons per hectare (60%) and the weight of 1000 grains by 21.43% compared to the conventional system.

The purpose of this study was to determine the effect of giving various concentrations of growth regulators (ZPT) on the growth of IRR 112 clone rubber sleeping eye stum. This research was carried out at SMK-PP Negeri Sembawa located in Lalang Sembawa Village, Sembawa District, Banyuasin Regency, South Sumatra. This research starts on the 4th week of September until the 1st week of December 2022. Based on the research results obtained, it can be concluded that the administration of Atonik growth regulator with P3 concentration (2 ml ZPT Atonik /l water) gave the highest yield at the age of 8 MST obtained a shoot length of 25.71 cm and a shoot diameter of 0.81 cm , and at the age of 10 WAP, the shoot height was 29.00 cm and the diameter of the shoot was 0.95 cm and the number of leaves was 36.00 in IRR 112 clone IRR 112 eye stum sleep rubber seedlings.

This study aims to determine the response of flower cabbage plants (Brassica oleraceae var Botrytis L.) to the growth and yield due to the provision of various doses of Bokashi fertilizer in lowland areas. This research was conducted in Purwosari Village, Sembawa District, Banyuasin Regency, which started from September 2017 until November 2017. This research was conducted by (experiment) Randomized Block Design (RAK) method consisting of 6 treatments and 4 replications. The treatment in this study was P0 = without Bokashi / ha (control), P1 = 10 tons of Bokashi / ha (50 g / polybag) fertilizer, P2 = 15 tons of Bokashi / ha (75 g/ polybag) fertilizer, P3 = 20 tons fertilizer Bokashi / ha (100 g/ polybag), P4 = 25 tons of Bokashi / ha (125 g/ polybag) fertilizer, P5 = 30 tons of Bokashi / ha (150 g/ polybag) fertilizer. The observed variables were number of leaf (strands), plant height (cm), day of flower (day after planting), flower diameter (cm), fresh weight of plant flower (g), fresh weight of plant stalk (g). Based on the results of the research that has been carried out it can be concluded that: 1) The administration of Bokashi fertilizer has not affected the growth of flower cabbage (Brassica oleraceae var. Botrytis L.) plants in polybag, but has a good effect on the results. 2) The administration of Bokashi fertilizer did not show differences for all treatments on plant height, number of leaves and day of flowering, but gave a difference in the diameter of the flower, the fresh weight of the flower of the plant and the fresh weight of the plants. 3) The provision of 150 g of Bokashi / polybag produced flower cabbage plants, namely the flower diameter of 11.30 cm, the fresh weight of flowers at 108.04 g / plant and the fresh weight of berries of 193.69 g / plant.
