Abstract: Essential nutrient needs for the growth of sweet corn can be fulfilled by the fertilization process. The combination of NPK+Mg fertilizer is one of the options to obtain adequate nutrient availability and increase sweet corn yield. This research aimed to determine the effect of NPK+Mg fertilizer on potassium availability, potassium uptake, and yield of sweet corn (Zea mays saccharata Sturt) Talenta variety in Inceptisols Jatinangor. This experiment was conducted at research field of Soil Fertility and Plant Nutrition, Department of Soil Science and Land Resources, Faculty of Agriculture, Universitas Padjadjaran from May to August 2019. The experimental design that had been used in this research was Randomized Block Design (RDB), which consisted 6 treatments of 1 control treatment, 1 standard NPK fertilizer treatment, and 4 treatments of NPK 12:12:17+9 MgO in different dosage. Each treatment was repeated four times so that there were 24 experimental plots. The results showed that the combination of NPK+Mg fertilization gave significant effect to the potassium availability, potassium uptake, and yield of sweet corn. 1 dosage of NPK+Mg fertilization (250 kg ha-1) gave the best effect on increasing potassium availability of 2,25 cmol kg-1, potassium uptake of 1,50%, and the yield of sweet corn of 8,68 ton hectare-1 in Inceptisols Jatinangor.

Abstract: Almost all farmers in Ethiopia were depending on rainfall for their agricultural activities. Even if farmers depend on rainfall, climate change, especially drought highly affect the productivity of farmers in the country in general. The main objective of this review is to review household perception on climate change, adaptation strategies and determinants of choice of climate change adaptation strategies in Ethiopia. For this review secondary data was collected from published and unpublished documents related to this topic and organized. From the reviewed published and unpublished documents, smallholder farmers perceive climate change through local knowledge and their past experience rather than scientifically identified perception using GIS and remote sensing technology, farmers employed different climate change adaptation strategies such as cultivating different crops, planting different crop varieties, changing planting dates, use of soil and water conservation techniques, conservation agriculture practices and engaging in non-farm income activities. From the review result access to information, farming experience, number of households in one village, distance to main market, and income of household, and agro-ecological settings influenced farmers’ adaptation choices to climate change.
