Abstract The study was aimed to analysis determinants of inorganic fertilizer use intensity on cereal crops among small holders in Toke Kutaye District, West Shewa Zone, Ethiopia. Correctional data were collected from 156 respondents using two stage random sampling methods. Data analyses were carried out using descriptive statistics and Double hurdle model. Result of the first hurdle reveals that out of twelve explanatory variables Sex ,Education, Off/non-farm income, Land size and Improved seed were determine positively whereas Age and Distance from nearest market determine small holders use of inorganic fertilizer negatively. The result of second stage of double hurdle model indicate that, out of twelve explanatory variables Sex, family size and Land size were positively affect extent (intensity) of inorganic fertilizer use whereas Age and Distance of household from nearest market determine use intensity negatively. Therefore, these results implied that there is a room to increase inorganic fertilizer use intensity on cereal crop productions. Hence, Farmers capacity to purchase this input beginning from lower income farmers to model farmers should be acknowledged; and should be designed the means to address those who have no ability to use inorganic fertilizer in their own farm through diverse development interventions.

<p>This work examines the factors that influence whether or not a farmer applies inorganic fertilizer in the Ghanaian context. Current maize yields in Ghana average only one-third of their estimated potential, but this yield gap can be reduced by improving farming practices and growing conditions in Ghana; specifically, yields in Ghana can likely be increased by intensifying the use of inorganic fertilizer, other inputs, and irrigation systems. Recently, Ghana introduced a fertilizer subsidy program to help increase fertilizer-use rates. This paper examines alternate instruments for increasing fertilizer use by determining farm-holder characteristics correlated with inorganic fertilizer use. The results show that the farmer's distance from the closest weekly market, whether the farmer has a pre-harvest contract, and whether the farmer has property rights on the field have a significant effect on fertilizer use.</p>

The Comparison of Hot Chili Farming Incomes by Using Organic Fertilizer and Mixture Fertilizer (Organic, and Inorganic)(Case Study In Subak Kudungan, Bontihing Village, Kubutambahan Distric,Buleleng Regency)The problem faced by famers of hot chili is obstacle the cultivation which done from the less production result of achieve national potential target of 10 to 20 tonnes/ha and to overcome obstacles especially in plants cultivation which done by applying a low-tech chemical inputs and cultivation technology of conservation which is implemented in integrated crop processing hot chili by applying organic fertilizer. Therefore this research aims to know the comparison of hot chili farming incomes by using organic fertilizer and mixture fertilizer. This research was conducted from August until September 2016 in Subak Kudungan Bontihing village Kubutambahan distric Buleleng regency. The data were analyzed by income analysis, R/C ratio analysis and Uji-t analysis. The results showed that hot chili farming incomes in one season per hectare using inorganic fertilizer is loweer than using a mixture fertilizer, use inorganic fertilizer Rp 21. 586.846,00 and use mixture fertilizer Rp 26.489.791,00. R/C ratio hot chili farming using organic fertilizer which is 2,09 higher than using mixture fertilizer 2,03. The result of Uji-t analysis showed hot chili farming incomes using inorganic fertilizer and mixture fertilizer was not significantly different at the level 5%.

Abstract. In addition to enhancing agricultural productivity, synthetic nitrogen (N) and phosphorous (P) fertilizer application in croplands dramatically alters global nutrient budget, water quality, greenhouse gas balance, and their feedback to the climate system. However, due to the lack of geospatial fertilizer input data, current Earth system and land surface modeling studies have to ignore or use oversimplified data (e.g., static, spatially uniform fertilizer use) to characterize agricultural N and P input over decadal or century-long periods. In this study, we therefore develop global time series gridded data of annual synthetic N and P fertilizer use rate in agricultural lands, matched with HYDE 3.2 historical land use maps, at a resolution of 0.5°  ×  0.5° latitude–longitude during 1961–2013. Our data indicate N and P fertilizer use rates on per unit cropland area increased by approximately 8 times and 3 times, respectively, since the year 1961 when IFA (International Fertilizer Industry Association) and FAO (Food and Agricultural Organization) surveys of country-level fertilizer input became available. Considering cropland expansion, the increase in total fertilizer consumption is even larger. Hotspots of agricultural N fertilizer application shifted from the US and western Europe in the 1960s to eastern Asia in the early 21st century. P fertilizer input shows a similar pattern with an additional current hotspot in Brazil. We found a global increase in fertilizer N ∕ P ratio by 0.8 g N g−1 P per decade (p < 0.05) during 1961–2013, which may have an important global implication for human impacts on agroecosystem functions in the long run. Our data can serve as one of critical input drivers for regional and global models to assess the impacts of nutrient enrichment on climate system, water resources, food security, etc. Datasets available at doi:10.1594/PANGAEA.863323.
