Abstract

This study was conducted to determine the response of corn plants to the second cob pruning treatment and liquid complementary fertilizer (LCF) spraying on the Growth and Production of Waxy Corn Plants (Zea mays ceratina L.). This study was conducted at the Experimental Garden of Pabentengan Bajeng Village, Gowa Regency, South Sulawesi, from September to December 2018. The materials used in this study were local waxy corn seeds, liquid complementary fertilizer (Bram Evolution) urea and NPK fertilizer. The Split Plot Design method was used. The main plot is without pruning and with pruning, while the sub-plot is Spraying Liquid Complementary Fertilizer (LCF) consisting of 4 levels, namely without LCF spraying, spraying with a concentration of 10 mL/L water, 20 mL/L water, and 30 mL/L water, 8 treatment combinations repeated 3 times to obtain 24 experimental units. The results of this study indicate that pruning the second cob increases the dry weight of the plant, seed weight per plant, seed weight per plot, and seed weight per hectare. LCF spraying and the interaction between pruning and LCF spraying treatments did not affect the observed parameters

Abstract

Red chilli productivity is influenced by land suitability, climatic factors, and nutrient content. Various ways are done and continue to be developed to overcome land problems with actual soil conditions that are not suitable, as well as to overcome the constraints of high rainfall. The purpose of the study was to determine the actual and potential land suitability and inhibiting factors for large chilli plants in Gantarang District. The results of actual land suitability are marginal suitability (S3) with limiting factors of water availability (high rainfall) in all land units and rooting media (soil depth) in land units 4 and 7. Improvement efforts made for high rainfall are by making drainage channels, raising beds, and planting at the end of the rainy season. Improvement efforts with the limiting factor of soil depth in land units 4 and 7 are tillage on solid, soft, and thin layers. Efforts to improve soil depth require sophisticated tools and technology, and high costs.

Abstract

This research was conducted in Kampili Watershed, South Sulawesi. This research was conducted from February to April 2021. This study was conducted using USLE method and USLE formula as an analysis tool to determine the rate of erosion and tolerable erosion as well as identification of damaged land in the Kampili watershed of south Sulawesi. The results showed the rate of erosion that occurs in each land use, namely, in plantation land use has an erosion rate of 94.54-ton ha-1 per year, in the use of mixed plantation land medium density has an erosion rate of 281.10-ton ha-1 per year, in the use of rice fields has an erosion rate of 4.13-ton ha-1 per year and in the use of open land has an erosion rate of 853.53-ton ha-1 per year. The value of erosion that can be tolerated (T) of each land use is, in the use of farmland has a value of T of 17.66-ton ha-1 per year, in the use of mixed garden land density has a value of T of 15.99-ton ha-1 per year, in the use of rice fields has a value of T of 16.40, in the use of open land has a value of T of 12.25-ton ha-1 per year. Meanwhile, for the identification of damaged lands is determined by looking at the value of erosion class that is light, very light, medium, heavy and very heavy.
