Amy Falila — 2026-06-30

This study was conducted to evaluate the growth and yield responses of rice (Oryza sativa L.) varieties Inpara 3 and Inpara 9 to the application of NPK fertilizer under a floating cultivation system. The experiment was carried out at Lebak Pond, Jakabaring Sport Center, Palembang, South Sumatra, from June to September 2025. A Randomized Block Design (RCBD) was employed, consisting of three levels of NPK (16:16:16) fertilizer application, namely 8.4, 9.9, and 11.4 g plant⁻¹. Observed variables included plant height, number of productive tillers, 1000-grain weight, grain weight per clump, fresh and dry biomass per clump, and number of grains per panicle. Supporting parameters such as chlorophyll content, pH, and climatic conditions were also recorded.significantly affected almost all growth and yield parameters for both rice varieties. This study demonstrates that an NPK dose of 8.4 g/pot (P1) tends to provide the most efficient and optimal growth response for floating rice in swamp land conditions. The Inpara 9 variety generally exhibited superior vegetative growth and several yield components compared to Inpara 3, as evidenced by plant height (114.67 cm); productive tillers (39.56); fresh stover weight (176.94 g); dry stover weight (103.41 g) and grains per panicle (91.00). However, Inpara 3 outperformed in specific yield components, namely 1000-grain weight (26.04 g) and grain weight per hill (70.06 g).

This study aimed to determine the response of sweet corn (Zea mays sacchara Sturt.) to cow manure fertilizer application at various planting distances. This research was conducted at the experimental garden of the Faculty of Agriculture, Tridinanti University, located in Pulau Semambu Village, North Indralaya District, Ogan Ilir Regency, South Sumatra Province. The research was conducted from May to June 2025. This research method used a Randomized Block Design (RBD) with 6 (six) treatments and 4 (four) replications. The number of samples observed in each experimental unit was 4 (four) plants. The treatments in this study were P1 = 10 tons of cow dung manure / ha (7.2 kg / plot) with a planting distance of 40 cm x 30 cm, P2 = 10 tons of cow dung manure / ha (7.2 kg / plot) with a planting distance of 40 cm x 40 cm, P3 = 10 tons of cow dung manure / ha (7.2 kg / plot) with a planting distance of 40 cm x 60 cm, P4 = 20 tons of cow dung manure / ha (14.4 kg / plot) with a planting distance of 40 cm x 30 cm, P5 = 20 tons of cow dung manure / ha (14.4 kg / plot) with a planting distance of 40 cm x 40 cm and P6 = 20 tons of cow dung manure / ha (14.4 kg / plot) with a planting distance of 40 cm x 60 cm. The variables observed were: plant height and leaf area at the ages of 2, 4 and 6 WAP, cob diameter without husk, cob weight with husk per plant, cob weight without husk per plant and cob length. Based on the research results, it can be concluded that the P2 treatment (10 tons of cow dung manure/ha (7.2 kg/plot) with a planting distance of 40 cm x 40 cm) produced the highest plant height at 6 WAP of 167.83 cm, the widest leaf area at 6 WAP of 2,006.13 cm2, the largest diameter of the cob without husk was 44.05 mm, the heaviest weight of the cob with husk per plant was 377.75 g, the heaviest weight of the cob without husk per plant was 319.75 g and the longest cob length was 25.63 cm.

This study aimed to determine the growth response of sugarcane (Saccharum officinarum L.) seedlings of the Bunga Mayang 1650 (BM 1650) variety to the application of chicken manure in polybags. The research was conducted at PT. Sinergi Gula Nusantara MKSO Unit Cinta Manis, Ogan Ilir, South Sumatra, from 1 July to early 3 October 2025. The experimental method used was a Randomized Block Design (RBD) with 5 treatments and 5 replications. Each experimental unit consisted of 3 sample plants. The treatments applied were as follows: P0 = 0 grams of chicken manure/polybag, P1 = 25 grams/polybag equivalent to 5 tons/ha, P2 = 50 grams/polybag equivalent to 10 tons/ha, P3 = 75 grams/polybag equivalent to 15 tons/ha, and P4 = 100 grams/polybag equivalent to 20 tons/ha. The observed parameters included plant height (cm), number of leaves (leaves), leaf area (cm²), stem diameter (mm), number of internodes, and chlorophyll content (mg/L). The results showed that the application of chicken manure had a highly significant effect on the growth of sugarcane (Saccharum officinarum L.) seedlings. The treatment of chicken manure at 50 grams/polybag (equivalent to 10 tons/ha) produced the best results, as indicated by growth parameters such as plant height, number of leaves, leaf area, stem diameter, and the number of internodes had no significant effect on chlorophyll content.

Maharani — 2026-06-30

This research aims to determine the growth of rice plants of Mapan P05 and Hipa 21 rice varieties due to the application of NPK fertilizer in the floating raft cultivation system. This research was carried out in the Blackwater pool Lebak Jakabaring Sport Center area, Palembang, South Sumatera, which took place from Week 2 (Two) of June 2025 to Week 3 (Three) September 2025. The research design used is Randomized Block Design (RAK). The treatment tested consists of three levels of NPK fertilizer dosage (16:16:16), namely P1 (8.4 grams/plant), P2 (9.9 grams/plant), and P3 (11.4 grams/plant). The observed parameters consist of plant height (cm), the number of overall and productive tillers, weight of 1000 grains (g), grain weight per pot (g), dry weight per pot (g), chlorophyll content, soil pH and water pH. The research results show that the application of NPK fertilizer has a real to very real effect on almost all growth and yield parameters in both rice varieties. This study proves that the dose of NPK fertilizer 11.4 g/plant of the Mapan P05 Variety has a higher and more productive yield potential compared to the Hipa 21 Variety, shown by the total number of tillers 37, 22, the number of productive tillers 34.11, weight of 1000 grains 26.04 g, grain weight 108.90 g and dry seed weight 84,51 g, while the Hipa 21 variety is only superior in plant height of 115.04 cm.

Muhamad Roihan — 2026-06-30

This study aims to determine the response of growth and production of rice plants of Inpari WBC 13 variety due to NPK Mutiara fertilizer doses in a floating farming system. The research was conducted in the Kolam Lebak Jakabaring Sport Center area, Palembang, South Sumatra, from the second week of June 2025 to the third week of September 2025. The research method used was a Randomized Block Design (RBD). The treatments tested consisted of three levels of NPK fertilizer (16:16:16), namely P1 (8.4 g/pot), P2 (9.9 g/pot), and P3 (11.4 g/pot). The observed parameters included main parameters and supporting parameters. The main parameters consisted of plant height (cm), total number of tillers, number of productive tillers, weight of 1000 grains (g), grain weight per pot (g), and dry biomass weight per pot (g). Supporting parameters included chlorophyll content, soil pH, and water pH. The results showed that the application of NPK fertilizer had a significant to highly significant effect on most growth and yield parameters. The NPK fertilizer dose P2 (9.9 g/pot) showed the most optimal growth and yield response in the floating rice cultivation system in swampy lowland areas. The Inpari WBC 13 variety tended to show better vegetative growth, as indicated by higher plant height and total number of tillers.
