Book Description
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.

Book Description
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.

Book Description
Maize is an important food crop in Ghana, accounting for more than 50 percent of the countrys total cereal production. The Ghana Grains Development Project (19791997) and the Food Crops Development Project (20002008) 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.

Book Description
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.
