Maize phenology as an indicator of climate change simulated by RegCM4 under RCP4.5 and RCP8.5 in Mozambique

The IPCC fifth assessment report indicates an increase in air temperature under future scenarios over Mozambique. It may affect the development cycle and length of phenological stages of maize, and compromise the agricultural activity in Mozambique. The goal is to quantify the response of maize phenology to referred projected changes in climate, especially highlighting changes in air temperature patterns over...

Comparison of the effectiveness of heterotic grouping methods in classifying intermediate maturing maize (Zea mays L.) inbred lines under stressful and non-stressful environments

The effectiveness of a hybrid breeding program depends on the heterotic patterns that can be used to utilize grain-yield heterosis. This study was carried out to (a) categorize inbred lines into heterotic groups using three different methods and (b) determine the most effective heterotic grouping method for categorizing set of inbred lines.  A total of 96 hybrids generated from thirty-two set of inbred lines...

Heterosis, combining ability and reaction of tomato parental lines and their F1 hybrids to bacterial wilt caused by Ralstonia solanacearum in Kenya

Strategies to manage bacterial wilt disease causing 64-100% yield loss have limited effectiveness. A 10×10 diallel mating design excluding reciprocals and self was employed in this study to evaluate combing ability effects, heterosis, and reaction to bacterial wilt in 10 tomato parents. Genotypes AVTO1424 (11.87%), AVTO1429 (12.29%) and AVTO1314 (13.53%) were found to have significantly lower disease incidence,...

Role of income from rice cultivation on livelihoods of rice farmers: Evidence from Ahero Region, Kenya

In Africa, the demand for rice has increased rapidly as urbanization progresses and assistance is being provided to improve productivity and rice farming management. In the rice-cultivation area near Lake Victoria in western Kenya, where farmers are called “outgrowers”, wage labor costs put pressure on rice farming and reduce profits. However, wage laborers were rice farmers living in the same area. The...

Environmental effects on sugarcane growth from on-farm data in the Brazilian Midwest

Climate and soil water availability are factors that influence the growth and yield of sugarcane. These factors can also serve as valuable indicators for predicting maturity and biometric changes in sugarcane, and also enhanced productivity. The aim of this study was to determine the biometric and sucrose accumulation responses of surgarcane as a function of agrometeorological data and soil water storage. The study was...

Genetic diversity of Cleome gynandra germplasm in Burkina Faso using SSRs molecular markers

Cleome gynandra L. is an important traditional leafy vegetable in Burkina Faso diets. Because of its high nutritional value, it makes a good dietary supplement, providing an important nutritional and medicinal requirement. The aim of the present study was to assess the genetic diversity and intra- and interpopulation relationships of the C. gynandra collection using SSR molecular markers specific to C. gynandra. Nine...

Opportunities, perceptions and challenges in production and use of traditional grains in Semi-Arid Masvingo District, Zimbabwe

This paper aims to understand farmers’ perceptions and challenges in production and use of traditional grains as well as feed manufacturers perceptions on inclusion of traditional grains in feed formulations. The study also seeks to ascertain the opportunities for increased adoption of traditional grains as an adaptive strategy to climate change. Climate change has contributed to a shift in seasons and...

Genotype and Environment Interaction for yield performance of 12 Advanced Tongil rice genotypes with Doubled Haploid Background under Salts tress conditions in Tanzania

Rice (Oryza sativa L.) is an important global food commodity crop. Its yield was affected by genotype, environment, and the interaction between genotype and environment that demands the development of diverse tolerant rice to increase yields and adaptation. Genotype and Environment interaction for yields of rice Tongil types with doubled haploid (DH) were evaluated in three locations. A randomized complete block design...
