This book was released on 2018-02-13 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is the most widely grown starch in Ghana, and yet domestic supply does not meet demand, because maize productivity is low. Trials were performed in northern Ghana in 2015 to determine whether hybrid varieties would outperform the varieties planted by farmers and, therefore, increase maize productivity. Two foreign hybrids performed consistently better then Obaatanpa, the most widely used variety in the north. In 2016, Adikanfo, the best performing hybrid, and certified Obaatanpa were made available for purchase at subsidized rates in the communities where the 2015 trials had been conducted. A survey was then carried out to study whether the trials had any effect on technology uptake or behavioral change among farmers in the region and if the varieties performed as well on the farmers’ fields as in the trials. This paper presents the descriptive results of the survey.

This book was released on 2018-02-07 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is an important staple crop in Ghana, but maize productivity is low. Other countries with similar agroecological conditions have increased maize productivity by increasing the use of maize hybrids. This paper presents the results of maize trials in northern Ghana, in which hybrids were tested to see if they performed significantly better than the varieties planted by farmers. This paper details the procedures of the maize trials and presents descriptive statistics of the trial results. The trials demonstrated that two foreign hybrids performed consistently better than Obaatanpa, the most widely used variety in the north. The foreign hybrids performed consistently well in all districts and appear to be well-suited for planting in northern Ghana.

This book was released on 2021-04-13 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report examines the evolution of farm input subsidy programs in Ghana, with a focus on the Planting for Food and Jobs (PFJ) initiative, which was introduced in 2017 and replaced the Fertilizer Subsidy Program (FSP) that was launched in 2008. A review of PFJ implementation reports and other official data sources reveal that information on general program features, such as beneficiary numbers, subsidized input quantities, and program budget is readily available and useful for understanding program design and implementation. National crop production estimates are also reported annually, and these provide evidence of rapid output growth in the agricultural sector, especially within the cereals subsector. However, the implementing agency, the Ministry of Food and Agriculture (MoFA), lacks a system for closely monitoring and reporting PFJ program impacts at farm-level. Consequently, most of the published information on the marginal contribution of PFJ to national crop output is based on simulations, which make strong assumptions about seeding rates, fertilizer use by crop, and input use efficiency on beneficiary farms. With this drawback in mind, these simulations show that PFJ contributed substantially to crop output growth, a result which is not implausible considering the quantities of inputs provided, but one that requires further on-farm validation. Recommendations are offered around beneficiary targeting, interpretation of employment impacts, and the need for regular monitoring of farm-level impacts, all of which will help improve transparency of the program.

Book excerpt: Kenya will increasingly rely on modern agricultural technology to increase productivity since land extensification is no longer a feasible option to satisfy national food demands. The purpose of this thesis was to investigate the factors that affect the adoption of improved maize varieties in Kenya and the influence of farmers' preference on maize varieties. A field survey of 444 Kenya farm households was conducted by the University of Nairobi. A discrete choice model was constructed to determine the impact of demographic and socioeconomic variables and farmers' perception on the choice producers make between open pollinated varieties (OPV) and hybrid maize varieties. The importance of maize performance characteristics were identified by stated preferences of producers' weights of those characteristics across all farmers. Results indicated that producers stated preferences for choosing hybrid versus OPV have the most significant effect on the adoption and use of hybrid maize. Land preparation technique, drought effect, distance to market, age, gender, education level and occupation of the household head were also found to have significant influences. Improved yield performance is the most important characteristic. According to farmers' perceptions, hybrid maize performs worse than OPV maize in drought escape, which has a negative impact on hybrid maize adoption. Results suggest that yield potential was the greatest advantage for hybrid maize varieties, and also the most significant characteristic a household considered when make adoption decisions (39.66% weight). Maintaining the current levels of yield performance and finding ways to narrow the yield gap are the primary matters for future maize varieties, not only for hybrid maize, but also GM maize. Hybrid maize has poor performance on drought escape, and drought has a negative effect on hybrid adoption. It is necessary to improve the drought escape performance for the future maize varieties. Lower income families have a lower adoption rate on hybrid maize varieties, which indicates that the input including seed and fertilizer were burdens for low income family. Reducing the input cost and implementing credit contracts will increase adoption of new maize varieties.

Available in PDF, EPUB and Kindle. Book excerpt: Maize is an important food crop in Ghana, accounting for more than 50 percent of the country’s total cereal production. The Ghana Grains Development Project (1979–1997) and the Food Crops Development Project (2000–2008) made major investments to improve maize yield. Despite these efforts, the average maize yield in Ghana remains one of the lowest in the world, much lower than the average for Africa south of the Sahara.

This book was released on 2011-02 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is one of the most important staple crops in the world. To feed ever burgeoning population, there is a need to increase production and productivity of the crop. Adoption of hybrid maize technology led to the substantial increase in total maize production. However, small farmers, who are constrained with the relatively high inputs requirement of hybrids. This book describes about the method how reduction of cost and enhancing of maize production could be done by mixing hybrids and open pollinated varieties (OPVs) in a sustainable manner thereby providing options to the resource poor farmers. Likewise, it describes about the agronomic manipulation of increased maize production techniques through mixed culture of different combination of maize seed between hybrids and OPVs. Also, it explains how substitution of hybrid seeds with OPVs up to 50% proves economically sound alternative practice of maize production system for resource poor growers in general and developing country in particular. Likewise, it provides information on economic benefit of mixed cultivar culture of maize for increasing production as well.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In mid-hill of Nepal, the cereal-legume intercropping has popularly been practice to optimize yield potentiality and profitability, however, intercropping facilitating variety of maize are hardly tested. A field experiment was conducted at Agriculture Knowledge Center, Ghyalchowk, Gorkha in 2021/22 to explore the yield performance of maize varieties in sole and intercropping and to determine the possibilities of improvement of intercropping productivity through selection of suitable varieties. The four maize varieties [viz., Arun-2, Rampur composite, Rampur hybrid-10, Rasi-3033 hybrid] were planted in randomized complete block design lay-out to compare the suitability of different maize varieties in intercropping. Field experiment showed average grain yield of maize intercropped with cowpea was reduced non-significantly, however the open pollinated varieties (namely Arun-2 & Rampur composite) produced significantly lower grain yield, mainly due to lower number of kernel rows, number of kernels and test weight. The number of kernel rows, number of kernels and test weight were statistically similar between Rasi-3033 hybrid and Rampur hybrid-10 in both sole and intercropping system, so their grain yield was not greatly changed in intercropping. The major yield component for restricting yield in intercrop was number of kernels/row with higher coefficient of determination. However, test weight was the most important limiting factor in sole. In overall, hybrids varieties yields outstanding than OPV's indicates that hybrids are good for better intercropping yield productivity to farmers.
