Abstract

The Indonesian Government's efforts to enhance Human Resource (HR) quality include ensuring adequate food production, purchasing power, access, and nutritional intake. This study aims to assess the impact of single and mixed herbicides on corn plant growth and yield. Employing a Randomized Block Design (RBD) with eight treatments replicated three times, the research was conducted from February to June 2023 at the Farmer's Gar-den. Results indicated that herbicide treatments, particularly those with atrazine + saflufenacil as the active in-gredients, demonstrated the most favorable effects on plant height at 6 WAP and 8 WAP, the number of leaves at 6 WAP, ear length, ear weight, and dry seed weight per plot. The atrazine + saflufenacil herbicide treatment had the best effect on plant height at 6 WAP and 8 WAP, number of leaves at 6 WAP, ear length, ear weight, and dry seed weight per plot.

Ammar M, Susilawati S, Irmawati I, Harun MU, Achadi T, Sodikin E, Wulandari SS. 2022. The application of  NPK  fertilizer on growth and yields of kale (Ipomoea reptans poir.) in floating system. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 628-634. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).South Sumatra Province is a province with great swampland potential. One of the uses of lebak swamp land is by floating cultivation. Floating cultivation in this study used a raft made of 10 bamboos with a size of 2x1 M. This study aimed to determine the effect of npk fertilizer application on the growth and yield of land kale plants in a floating manner. This research was carried out Embung on the campus of Sriwijaya Indralaya University, from May to July 2022. The study was prepared using a Randomized Group Design (RGD) with 4 treatments, each treatment was repeated 3 times and received 12 treatment units, each treatment unit had 3 plants, so that the total number of plants was 36 plants. P0= Control P1= 0.5 g NPK/polybag P2= 1 g NPK/polybag P3= 1.5 g NPK/polybag. Observed parameters include plant height, number of leaves, degree of leaf greenness, leaf area, fresh weight of the crown, fresh weight of the leaves, fresh weight of the roots, length of the roots, dry weight of the crown, dry weight of the leaves and dry weight of the roots. Based on the results of the study, it was shown that the administration of the recommended dose of NPK fertilizer P2 = 1 g NPK/Polybag gave the best results compared to other dose treatments.

Abstract

Shallot (Allium ascalonicum L.) can be cultivated across a wide range of altitudes, from lowlands to highlands; however, production in Indonesia is predominantly conducted on dryland areas. In response to the national program promoting shallot production expansion outside Java, the development of shallot cultivation in South Sumatra faces challenges due to extensive wetland conditions. Floating cultivation systems offer a potential alternative for optimizing wetland utilization. This study aimed to evaluate the adaptability and performance of several shallot varieties under floating cultivation with different rates of chicken manure application. Plant analysis was carried out at the Plant Physiology Laboratory, and the experiment was carried out from June to August 2024 at the Embung (research reservoir) and Experimental Garden, Faculty of Agriculture, Sriwijaya University, Indralaya. A randomized block design with two factors and three replications was applied. The first factor consisted of four shallot varieties (Tajuk, Bauji, Batu Ijo, and Bima Brebes), while the second factor involved chicken manure rates of 0, 10, 20, and 30 t ha⁻¹. Data were analyzed using RStudio and presented in tables and figures. The results showed that the Bauji variety exhibited superior growth and yield compared to the other varieties. Increasing chicken manure application up to 20 t ha⁻¹ significantly improved shallot growth and productivity. It can be concluded that the Bauji variety, combined with 10 t ha⁻¹ chicken manure, is suitable for cultivation using a floating system in tropical wetlands.
