Abstract

The aim of the study was to obtain proper technique for cultivating shallots of Bima Brebes variety through the use of chicken manure and NPK fertilizer on tidal land. The research was located on tidal land in Sukatani Village, Tanjung Lago District, Banyuasin Regency, South Sumatra Province, located at a position of 1.30° – 4.0° South Latitude and 104° 00' – 105° 35' East Longitude. The study used a randomized block design with one treatment factor and three replicates. The treatment was the dose of organic chicken manure with 5 levels, namely P0 = no chicken manure; P1 = 10 tons of manure per hectare; P2 = 15 tons of manure per hectare; P3 = 20 tons of manure per hectare; P4 = 25 tons of manure manure per hectare. Each treatment was mixed with NPK fertilizer at a dose of 200 kg NPK ha-1 (M). Data analysis was carried out by analysis of variance using F test and least significance difference (LSD) test. The variables observed were leaf length, leaf number, plant dry weight, specific leaf area, specific leaf weight, root-shoot ratio, relative growth rate, net assimilation rate, bulb fresh weight, bulb number, bulb diameter, bulb dry weight, and percentage of bulb shrinkage. The results showed that the use of chicken manure 10 tons/ha and 200 kg NPK/ha affected the growth of shallots on leaf length, root-shoot ratio, relative growth rate, bulb fresh weight and bulb dry weight. It was then concluded that it can increase the growth and yield of shallots of Bima Brebes variety on tidal land.

Abstract

The aimed of this study was to determine the effect of chicken manure application on red chili plants using conventional and floating cultivation techniques. The research was carried out on the experimental farm for conventional cultivation techniques and in research pond for floating cultivation located in the Faculty of Agriculture, Sriwijaya University, Indralaya Campus, Ogan Ilir, South Sumatra with an altitude of 10 m above sea level from July to November 2022. The experiment used a randomized block design with one factor, namely chicken manure (0, 10, 20 and 30 tons/ha) with three replications. While the floating experiment used 200 cm x 100 cm of bamboo rafts. Parameters observed included plant height, number of leaves, crown diameter, fruit length, fruit diameter, fruit weight per fruit, and total fruit weight per plant. Data were analyzed using Analysis of Variance (ANOVA) at the 5% level. The results showed that increasing the dose of chicken manure up to 30 tons/ha in both cultivation techniques increased plant height and number of leaves. Likewise for the number and weight of fruit, obtained at the same dose in conventional techniques, namely 30 tons/ha. However, fruit length and diameter parameters were higher in floating cultivation at all doses of chicken manure treatments. Therefore, it was concluded that the use of chicken manure could increase the growth of chili plants in both cultivation techniques, although the size of the polybags used could not support the growth and yields optimally.
