FOLIAR APPLICATION OF PHOSPHORUS, SULPHUR AND MICRONUTRIENTS OF ZINC AND IRON ON GROWTH AND YIELD OF RICE (Oryza sativa L.) UNDER RAINFED AND IRRIGATION IN THE GUINEA SAVANNA ECOLOGY OF GHANA

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...

LEAFSPOT DISEASE EPIDEMICS AND COMPONENTS OF RESISTANCE OF SELECTED GROUNDNUT (Arachis hypogaea L.) GENOTYPES IN GHANA

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...

EVALUATION OF ELITE SOYBEAN (Glycine max (L) Merril) GENOTYPES FOR NITROGEN NUTRITION, WATER USE EFFICIENCY AND GRAIN YIELD IN THE GUINEA SAVANNA AGRO ECOLOGICAL ZONE OF NORTHERN GHANA

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...

UPTAKE AND EFFICIENCY OF NITROGEN, PHOSPHORUS AND POTASSIUM IN MAIZE PRODUCTION AS INFLUENCED BY NEEM (Azadirachta indica L.) SOIL AMENDMENTS IN THE GUINEA SAVANNAH ECOLOGICAL ZONE OF GHANA

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...

RESPONSE OF MUTANT SOYBEAN (Glycine max L) GENOTYPES TO DROUGHT AND HIGH SOIL TEMPERATURE IN THE GUINEA SAVANNA AGROECOLOGY OF GHANA

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...

The effects of physical properties of common bean (Phaseolus vulgaris L.) varieties on soaking and cooking time

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...

Contribution of managed honeybees (Apis mellifera scutellata Lep.) to sunflower (Helianthus annuus L.) seed yield and quality

Abstract: Insects are considered to be responsible for 80-85% of all pollination, with honeybees being well known for their pollination services for many crops. The effect of managed honeybee pollination on sunflower seed yield and quality (germination percentage and oil content) was investigated at the University of Pretoria experimental farm and in commercial sunflower fields at Settlers. This was done through pollinator exclusion and pollinator surveys on sunflower field plots located at ...

GENETIC VARIABILITY AND ASSOCIATIONS OF YIELD AND YIELD RELATED TRAITS OF LENTIL (Lens culinaris Medik.) GENOTYPES AT DIRE DAWA, ETHIOPIA

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...

IN VITRO PROPAGATION OF SUGAR CANE (Saccharum Officinarum L. var. (Sp-70) THROUGH APICAL MERISTEM

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...

GENETIC VARIABILITY AND ASSOCIATION OF AGRONOMIC CHARACTERS IN COMMON BEAN (Phaseolus vulgaris L.), GROWN AT ZIWAY, EAST SHEWA, ETHIOPIA

Abstract: The purpose of this study was to estimate the extent of genetic variability of agronomic traits and their contribution to seed yield. Twelve quantitative characters including plant height, pods per plant, seeds per pod, days to flowering, seed yield per plots, harvest index and hundred seed weighted of twenty four genotypes of common bean (Phaseolus vulgaris L.) was studied. The experiment was conducted at Ziway farmer’s field as randomized complete block design planted in three ...

NUTRIENT FLOWS AND BALANCES UNDER CROP-LIVESTOCK FARMING SYSTEM OF YABALA, BEDELE DISTRICT, SOUTHWESTEREN OROMIA, ETHIOPIA

Abstract: Agricultural practices of smallholders with low external and internal inputs fluxes cause the risk of depleting soil nutrient stocks, seriously threatening future agricultural production potentials in Ethiopia. To curb soil fertility depletion in these areas, it needs quantification of fluxes that are responsible for nutrient import into and export out of the farming system. The objective of this study was to quantify nutrient fluxes, pools and NPK balances at farm and field scales...

IMPACT OF SALINITY STERESS ON SEED GERMINATION AND SEEDLING GROWTH ON SELECTED VARIETY OF TOMATO (LycopersiconesculentumMill.)

Abstract: Soil salinity is a major environmental issue threatening agricultural productivity worldwide. Therefore, screening for salt tolerant varieties is the most important and overcomes the salinity problems and treated with different saltconcentration.thus, this study aimed to study five selected tomato varieties collected from Awash Malkasa agriculture.

CLIMATE SMART CROP PRODUCTION TECHNOLOGY OPTIONS FOR ADAPTATION TO AND MITIGATION OF CLIMATE CHANGE IN GREAT RIFT VALLEY REGION OF ETHIOPIA

Abstract: Climate variability and change have serious direct and indirect consequences for crop production and nitrous oxide (N2O) emission in rainfed agriculture-based developing countries in general and in semi-arid environments like the Great Rift Valley (GRV) of Ethiopian particular. Agriculture is a sector that is vulnerable to the effects of climate change while it is contributing both as a sink and source to anthropogenic N2Oemission. Therefore, applying Climate Smart Crop Production ...
