Abstract Drought stress affects many maize growing regions in sub-Saharan Africa. As population increases, the gap between maize supply and demand increases. There is, therefore, need to develop maize lines that are tolerant to drought as well as amiable to Agrobacterium-mediated transformation. This study aimed to assess the competence of tropical maize lines after co-cultivation on Yeats Extract Peptone (YEP) media to Agrobacterium-mediated transformation and determine the relative express...
Maize is an important cereal crop that requires a high dose of fertilizer for optimum growth and productivity. While primary nutrients and sulphur are known to impact on the crop’s growth, data remains relatively scanty on the comparative productivity of these four nutrients. A field experiment was conducted at Bolgatanga municipality and Bongo district of Ghana during the 2020 cropping season to assess the relative agronomic productivity of each primary nutrient (N, P and K) and of sulphur...
An experiment to investigate the effects of nitrogen, phosphorus type and inoculation on grain yield of soybeans in two soil series. Soybean ranks first as an oilseed crop in the world and been a legume, it goes through a biological N-fixation process which is the second most important biological process after photosynthesis. Low soil fertility results in low crop yield which affects the livelihood of farmers and increasing yield of oil seed crops such as soybean has the potential to save Gha...
In Sub-Saharan Africa, rice is a staple food as well as a cash crop for both commercial and smallholder farmers. However, the yield is very low, because of inherent low soil fertility, as well as poor agronomic techniques. Multiple-location studies were conducted at Botanga (irrigated) and Nyankpala (rain-fed) to determine the most effective way to apply Zn and S to rice and to assess the effect of Zn and S, on rice grain yield. The treatments evaluated were foliar spray of NPK [Zn + S], NPK ...

The yield of soybean in Ghana stands at 1.45 t ha-1 out of an achievable harvest of 3 t ha-1 and among the contributory reasons for the low yields are inherent low soil fertility and lack of adequate indigenous bacteria in the soils used for soybean production. Amendment of the soil is believed to hold the key to improve yields of soybean. The objective of the study was to determine the effect of Bradyrhizobium japonicum inoculant (USDA 110 and USDA 136 stains) in combination with soil amendm...
Rice (Oryza sativa L.) is a widely cultivated cereal crop in varied environments. It is grown for its high-quality grains that are high in carbohydrates. Rice production has employed more than 20 million African farmers, and it is estimated that rice provides a living for roughly 100 million people. A field experiment was carried out at two locations during the 2020 farming season, to examine the relative responses of rice to soil P and foliar P, and if foliar P application could compensate f...
Abstract Leafspot disease is a major yield limiting factor in groundnut growing areas in Northern Ghana. This study was to monitor the progression of the disease in ten selected groundnut genotypes. Six were derived from a cross between BC3F6 interspecific introgression lines (43-09-03-02 or 60-02-03-02) and Spanish groundnut genotypes (Schubert and TS32-1) while the remaining four are released groundnut varieties in Ghana. Nkatiesari and Chinese served as the resistant and susceptible checks...
Abstract Nitrogen is very essential for every crop production due to its function in plant growth and development. It is an essential component of DNA and proteins which are the building blocks of life. Notwithstanding its vast importance, nitrogen is worldwide considered as one of the most limiting factors of production. The need to meet the huge nitrogen requirement has necessitated the use of synthetic fertilizer which continued application affects soil health, environment and agricultural...
Abstract The cultivation of maize (Zea mays L.) in northern Ghana is synonymous with fertilizer application, but efficient nutrient uptake and utilization are major factors that influence yield parameters and grain yield. The impact of neem cake (NC) and its oil as soil amendments on nutrient uptake and efficiency of Nitrogen (N), Phosphorus (P), and Potassium (K), as well as growth, yield components and yield of maize, was investigated. The trial was conducted at two locations, Tamale Techni...
Abstract The Department of Crop Science in the University for Development studies has produced mutant soybean genotypes with improved agronomic traits. A Series of evaluations of these mutant genotypes have been carried out at different agroecological zones in Ghana and high-yielding mutants such as 150 Gy, 200 Gy, 250 Gy, and 300 Gy have been identified. The present study used the above genotypes as planting material for the studies in the dry season and rainy seasons of the year 2020 to eva...
Abstract: Cookability of common bean is constrained by hardness which results to extend cooking times, low widespread consumption, and high cost of cooking fuel, the consequence of this is malnutrition due to nutritional deficiencies and food insecurity. A study was conducted in the seed Laboratory of Kenya Agricultural and Livestock Research Institute (KALRO)-Katumani to investigate the effects of physical properties of eleven bean varieties (GLPX92, KATX69, EMBEAN118, WAIRIMU, EMBEAN14, GL...

Abstract: Lentil (Lens culinaris Medikus) is a self-pollinated diploid (2n = 14) annual cool season legume crop that is produced throughout the world and valued as high protein food. Genetic diversity is essential for genetic improvement of crops to make selection and improvement for a given trait. The objective of the were study the genetic variation for different agronomic traits of lentil, the phenotypic and genotypic correlation coefficien0ts among these traits and the direct and indirec...
Abstract: Ethiopia’s sugar industry is increasing more than ever before and becoming one of the major pillars of the country’s economy. Conventional propagation of sugar cane has very low rate of multiplication and harbors diseases. This study was conducted to develop micropropagation techniques for rapid multiplication of disease-free sugarcane planting material through apical meristem explant. Sterile sugarcane variety (sp-70) was cultured on MS basal medium supplemented with BAP (0, 0...
