Abstract : The purpose of this study is to determine the impact of welfare distribution on import taxes. government revenues, consumer spending, producer revenues, efficiency losses (production, consumption, net effect) and level of competitiveness of cane sugar Indonesia by Domestic Resource Cost (DRC) calculation. This research was conducted from July to October 2022. The study used secondary data From relevant previous studies and other references such as journals, journals and bulletins Such. The findings show changes in government revenue, consumer surplus, Producer Surplus, Net Economic Losses in Production and Consumption, and Currency Gains Economicization is subject to import tariffs and price elasticities related to supply and demand. that It also showed that the competitiveness of Indonesian sugar products is higher than that of the same products. Other countries because the value of DRC is less than one..

Abstract : Hydroponics crop production has significantly increased in recent years worldwide, which allows an efficient use of water and fertilizers, as well as better control of climate and pest factors. Furthermore, hydroponics production under protected structure can increase crop quality and productivity, which results in higher competitiveness and economic incomes. The study was conducted to evaluate the postharvest quality of honeydew melon (Cucumis melo L. var. inoduros) under aggregate hydroponic system using inorganic and organic nutrient solutions. Randomized Complete Block Design (RCBD) was used in this study with two test factors: Factor A – with and without foliar application of fermented malunggay and Factor B- Organic and inorganic nutrient solutions and combinations, replicated three times. Results revealed that honeydew fruit were harvested at the average days of 56 with 80-95% plants survival. Postharvest quality and properties, the free radical scavenging activity (FRSA), Chlorophyll a and b, carotenoids, vitamin C and oxidation-reduction potential were significantly affected by the different treatments. FRSA was higher in honeydew melons applied with the combination of trichantera and commercial nutrient solution. Fermented golden snail treatment obtained the highest value of chlorophyll a and b and fermented trichantera gave the highest total carotenoids. Commercial nutrient solution and fermented trichantera obtained the highest vitamin C and Oxidation-reduction Potential, respectively..

Abstract : Tomato (Lycopersicon esculentum Mill.) is one of the top fruits in the Philippines with high nutritional value. The study was conducted to determine the effects of various safe phytochemical extracts and Calcium chloride (CaCl2) on the postharvest quality and shelf life of tomato under ambient temperature and identify the most effective treatment to improve tomato fruit quality. The study was laid out using Completely Randomized Design (CRD). Tomato fruits were dipped in different fruit extracts and combination of CaCl2: T1-hagimit, T2-hagimit+1% CaCl2, T3 - starfruit, T4 - starfruit+ 1% CaCl2, T5-cat's whisker, T6-cat's whisker+ 1% CaCl2, T7 –Pineapple, T8-Pineapple+ 1% CaCl2, T9 -1% CaCl2, T10 -Control (untreated). Phytochemicals derived from starfruit with 1% CaCl2 had significantly delayed tomato fruit softening than control and other treatments. Phytochemicals of pineapple alone, hagimit and cat’s whisker combined with calcium effectively decreased the respiration rate of tomato fruits until 40 days of storage. Percent weight loss, visual quality rating, shelflife, pH value, TSS (Brix) and TA (%) were not significantly affected. This result indicates that the application of phytochemicals combined with calcium chloride as coating improves the fruit quality of tomato..

Abstract : This study critically examined the effects of Total Factor Productivity on rice output in Nigeria. Data for this study such as land area, labour, capital and rice output from 1961 to 2020 were collected from various sources such as World Bank online statistical depository, United States Department of Agriculture Economic Research Service [26], [8], [16]. Data were analysed using descriptive such as mean and graph and inferential statistics such as Ordinary Least Square Regression model. Result from the study showed that although there is a positive trend in rice TFP in Nigeria over the years, the average rice TFP is regressive (i.e., less than 1). Furthermore, rice TFP (coefficient = 12.282; p<5%) had statistically significant effect on rice output. The study therefore recommended that promoting the adoption of modern technologies and improving management practices, policymakers can help enhance TFP and increase rice output, thereby improving food security and promoting economic development..

Abstract : This study examined the effect of rice production input variables and climate change variables on rice output in Nigeria. Data for this study such as temperature, rainfall, relative humidity, sunshine duration, land area, labour, capital and rice output from 1961 to 2020 were collected from various sources such as Nigeria Meteorological Agency (NIMET), World Bank online statistical depository, United Nations online database, United States Department of Agriculture Economic Research Service [22], Food and Agriculture Organisation Corporate Statistical Database [7], [14]. Data were analysed using descriptive and inferential statistics. Specifically, the study revealed that rice output in Nigeria had a positive slope for the period under review. Land (coefficient = 0.212; p<1%), rainfall (coefficient = 1612.441; p<5%), relative humidity (coefficient = -81289.210; p<5%) and temperature (coefficient = 324766.300; p<5%) had statistically significant effect on rice output. Based on the findings of this study, it therefore recommends that there is need for rice farmers to adopt artificial irrigation in order to mitigate the effect of climate change for optimum rice productivity..
