Correlation analysis for grain yield and other agronomic parameters for 90 single crosses hybrid maize evaluated in three agrological zones in Ghana
A trial was conducted to determine the correlation between grain yield and agronomic parameters of 90 F1 early maturing maize hybrids in 2012 in Fumesua, Ejura and Kpeve; representing the Forest, Forest-Savannah Transition and Coastal- Savannah Transition zones of Ghana, respectively. The objective of the work was to determine the correlation between grain yield and other agronomic parameters of maize across three...
An overview of tomato fruit-ripening mutants and their use in increasing shelf life of tomato fruits
The potential of tomato ripening mutants; rin, nor, alc, nr, gr, etc to prolong the shelf life of tomato cannot be overemphasized. Ripening mutants have gained a considerable attention in the last few years to extend shelf life. They have been characterized and examined for their potential utilization in lengthening shelf life of tomatoes. Mutant genes are therefore available to extend the shelf-life of tomato via...
Physico-chemical characterization of prickly pear (Opunicia Ficus indica) in the semi-arid region of Bahia State, Brazil
In Brazil, prickly pear has gained increasing attention, mainly due to its nutritional benefits of health promotion, however, its postharvest conservation is still incipient and has to be evaluated. The objective of this work was to evaluate the physical and physico-chemical characteristics of prickly pear from three municipalities in the semi-arid region of the state of Bahia-Brazil. The fruits were harvested at random...
Comparison of GGE biplot and AMMI analysis of multi-environment trial (MET) data to assess adaptability and stability of rice genotypes
Genotype × Environment (G×E) interaction and stability performance were investigated on paddy yield of eighteen rice genotypes and twelve locations using two well renowned statistical models; genotype main effect and G×E Biplot analysis (GGE) and additive main effects and multiplicative interaction (AMMI) analysis. The aim of this study was to elucidate the performance of some advance rice...
Determinants of smallholder farmersâ€™ awareness of agricultural extension devolution in Kenya
The devolved governance structure in Kenya places the provision of agricultural sector services such as extension at the local units. However, farmers’ awareness on this aspect and where services are available remains limited and often, there is confusion. In order to provide clarity and enhance the understanding of extension service delivery, this study sought to characterize farmers’ awareness of...
Effects of Schinus terebinthifolius extracts on the control of Sitophilus species in stored wheat grains
The objective of this study is to evaluate the efficacy of Schinus terebinthifolius extract in controlling the insects of stored wheat. The experimental design was completely randomized with 10 replicates in a factorial scheme of 4 × 9, for extracts (control, aqueous extract, and hydro alcoholic extract of 5 and 15% of Brazilian pepper tree) and nine dates of evaluation (3, 6, 9, 16, 23, 30, 37, 44 and 51 days)...
