Abstract

Cayenne pepper (Capsicum frutescens L.) was a plant that has high economic value. The application of phosphate fertilizers in inorganic forms is not friendly to the environment and is slowly available to plants. This research was carried out from October 2019 to January 2020 in Pancot Village, Kalisoro Village, Tawangmangu District, Karanganyar Regency with an altitude of 1200 meters above sea level and Andisol soil type. This study used a completely randomized design with two treatment factors (factorial), namely the first factor is the dose of fast soluble phosphate fertilizer namely 0 kg/ha (no SP36 fertilizer), 150 kg/ha (one application), 150 kg/ha (3 times application), 100 kg/ha (3 times application), and 50 kg/ha (3 times application). The second factor is the dose of chicken manure consisting of 2 levels, namely 0 tons/ha (no chicken manure), and 40 tons/ha. Parameters observed were plant height, flowering age, fresh weight of the plant, number of branches, and number of fruit per plant. The results showed that fast soluble phosphate fertilizer had a very significant effect on plant fresh weight and fruit number. Manure treatment has a significant effect on the parameters of plant height, fresh weight of the plant, total fruit per plant. The interaction of fast soluble phosphate fertilizer and manure had a significant effect on flowering age, fresh weight, and the number of fruits per plant. The best results were in the interaction of fast soluble phosphate fertilizer with a dose of 50 kg/ha and 40 tons/ha of manure.

Abstract

The study aims to identify the classes and the determinant factors of land suitability of Tobacco in order to provide recommendations for land management as an effort in increasing the development of Tobacco in Eromoko District, Wonogiri Regency, Indonesia. This research used a descriptive-exploratory approach by field surveys, laboratory analysis, and matching the data with growth requirement characteristics for Tobacco crops. The field survey was carried out based on a working map, namely the Land Mapping Unit (LMU), overlaid maps of soil type, slope, and rainfall. Research results illustrated that 18 LMUs were included in the marginally suitable class (S3) (4,968.78 ha, about 51% of research area) with limiting factors wa; oa; nr; na; eh, and 8 LMUs were included in the unsuitable class (N) (4,919.11 ha, about 49% of research area) with limiting factors N and eh. This study provide information about the land suitability class and the limiting factors each area to determine the potential success of Tobacco cultivation and make suitable improvement efforts. Keywords: Hilly land, Land management, Limiting factors, Sustainable agriculture, Tobacco growth potential.

Abstract

Sediment deposition in the upstream river areas can cause drought and disrupt agricultural activities. This study aims to analyze the potential for drought in the Keduang Sub Watershed based on the Land Map Unit. The Keduang Sub-Watershed area has high potential for the development of agricultural land for food crops, but is not free from the potential for drought. The study was conducted using a soil survey method that was strengthened by soil sampling and laboratory analysis. Parameters for determining soil damage that causes the potential for land drought include soil physical properties, namely specific gravity, structure, soil color, porosity, permeability, slope, and soil type. The results showed that the potential for drought at the research location was still high. This is influenced by the level of soil damage that varies from low, medium to high. Land drought can be an obstacle to agricultural activities, and improper land management can worsen the situation. Conservative actions to overcome this problem include the addition of organic matter, crop rotation, application of soil cover or mulch, and processing agricultural land according to the contour direction. These activities are expected to overcome soil damage so that the potential for drought can be overcome. Keywords: Conservation activities, Land drought, Physic soil properties, Soil damage.
