<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>

SUMMARYThis study investigated the feasibility of using sole organics or a combination of organics with inorganic fertilizer to improve maize production in on-station and on-farm experiments in central Kenya. In the on-station experiment, combined application of Calliandra calothyrsus, Leucaena trichandra and Tithonia diversifolia at 30 kg N ha−1 plus inorganic fertilizer (30 kg N ha−1) consistently gave significantly higher maize grain yields than the recommended rate of inorganic fertilizer (60 kg N ha−1). Sole application of calliandra, leucaena and tithonia also increased maize yields more than the recommended rate of inorganic fertilizer. In the on-farm experiment, calliandra, leucaena, tithonia and cattle manure either alone or combined with inorganic fertilizer increased maize yields with a similar magnitude to that of inorganic fertilizer. These organic resources could therefore be used to supplement inorganic fertilizer as a whole or in part. There was a yield gap between on-station and on-farm trials with on-station yields having, on average, 65% greater yields than the on-farm yields. There is therefore potential for increasing yields at the farm level by closing the yield gap.

Pressurized Irrigation

Climate change and water scarcity are the most important challenges of the agricultural sector, and pressurized irrigation systems (PISs) are one of the most significant ways to improve agricultural water productivity. The main purpose of this research was to identify the factors affecting the use of PISs by farmers. The statistical research population was a total of 2396 Iranian model farmers. The Cochran formula was used to determine the number of statistical samples. Accordingly, this comprised 331 people. The methodology of the study was mixed method research. The structural equation modeling technique, Mann–Whitney U, and Kruskal–Wallis tests were used to test the hypotheses. The results showed that the personal characteristics, tendency, attitude, self-efficacy, subjective norms, governmental support, environmental tensions, and technological features were the most important factors which influenced the farmers. It was found that all of these variables had a positive and significant relationship with the using of PISs by farmers, and they were able to predict 52% of the behavioral changes (R2) of the farmers. Among these variables, the attitude, with a path coefficient (β) of 0.48, had the highest impact on the using of PISs by the farmers.

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.

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%.
