Screening of guar accessions [Cyamopsis tetragonoloba (L.) Taub.] for higher yield potential under irrigated conditions

Twelve quantitative traits such as germination percentage, days to 50% flowering, plant height, branches plant-1, clusters plant-1, pod length, days to maturity, 1000-seed weight and grain yield plot-1 were studied to determinate ample variation and association between 100 Guar [Cyamopsis tetragonoloba (L.) Taub.] genotypes to screen out the best performing lines. Variance study of quantitative traits in various...

Stability analysis for yield and yield contributing characters in hybrid maize (Zea mays L.)

Twenty one hybrids along with two check varieties of maize were assessed for genotype environment interaction (GEI) and stability for selection of the best hybrid maize in three different Agro-Ecological Zones (AEZ) of Bangladesh during rabi season 2014/2015. The experiment was laid out in Randomized Complete Block Design with 3 replications. The additive main effects and multiplicative interaction (AMMI) model was used...

Genotype by environment interaction and yield stability of early maturing maize single cross hybrids at three locations in Southern Ghana

A grain yield trial was conducted in three locations in Southern Ghana. The objective of the trial was to determine the effects of genotype by environment interaction on 90 early maturing hybrid maize. The trial was conducted in Fumesua, Ejura and Kpeve; representing the forest, forest-Savanna transition and coastal-Savanna transition zones respectively. The analysis of variance for grain yield demonstrated that...

Effects of grass (Hyperenia spp.) mulching rate on development and yield of okra (Abelmoschus esculentus) under drip irrigation

Mulching minimizes water evaporation from cropped surfaces and increases efficiency of water utilization by the crops. A study was conducted between January to March and August to November 2015 in Zimbabwe, to establish the effect of different densities of thatch grass (Hyperrhenia filipendula) mulch on growth and yield of okra (Abelmoschus esculentus) under drip irrigation. The experiment was laid in a Randomized...
