Abstract

This study aims to determine the effect of chicken manure and NPK fertilizer as a basal fertilizer on Ultisol soil fertility and tomato plant yields and to find out the dose of chicken manure and NPK fertilizer as a basal fertilizer that affect both Ultisol soil fertility and tomato crop yields. This research was carried out at the Field Laboratory II of the Faculty of Agriculture and the Integrated Laboratory of Halu Oleo University, from March to June 2022. This study was conducted using a Randomized Block Design (RBD). The treatment tested was chicken manure and NPK fertilizer as a basal fertilizer consisting of 4 treatments, namely treatment without chicken manure (K0), chicken manure 200 g polybag-1 (K1), chicken manure 400 g polybag-1 (K2), chicken manure 600 g polybag-1 (K3). Each treatment was repeated by 3 tests, so there were 12 experimental units. The results showed that the application of chicken manure and NPK fertilizer as a basal fertilizer with various doses had an influence on soil fertility and tomato crop yields. In the K0 and K1 treatment, the fertility status was low, while the K2 and K3 treatment the fertility status increases to moderate, while the dose of chicken manure and NPK fertilizer as basal fertilizers that had higher on ultisol soil fertility and tomato plant yields, namely a dose of 600 g polybag-1 (K3) when compared to and a dose of 0 g polybag-1 (K0).

Abstract

Soil characteristics determine the potential yield of cultivated plants. Soil morphological characteristics generally differ between depths and locations, so different management efforts are required. This study aimed to determine the morphological characteristics of the soil in each layer and between sub-districts on upland rice cultivation land in North Buton Regency. The research method is based on free survey observations with an area administration approach to upland rice cultivation. Soil observation is carried out by drilling. Drilling is carried out to a depth of 120 cm or up to a layer of soil parent material. Qualitative soil descriptions have been carried out directly in the field to obtain an overview of soil morphological characteristics between layers and locations. The results showed the morphological characteristics of the soil on upland rice cultivation in North Buton Regency, where soil colors are generally brown (ranging from dark brown to yellowish brown; Hue 7.5-10 YR with low value and chroma respectively). Soil texture generally includes fine to medium texture, ranging from clay, silt to loam, except for the slightly coarse-textured Bonegunu area (sandy loam) in the subsoil layer. Soil consistency generally includes firm in moist conditions, plastic and sticky in wet conditions. Soil organic matter content is generally moderate, except for the Kambowa area which is low. While the soil pH levels, both between depths and locations, are in the slightly acidic category. It is necessary to pay attention to the differences in pedogenesis factors between locations in the management of upland rice cultivation in the North Buton Regency to realize optimal and sustainable productivity.
