Growth, yield and phosphorus use efficiency of potato varieties propagated from apical rooted cuttings under variable phosphorus rates

This study determined effect of phosphorus (P) rates on growth, yield and phosphorus use efficiency (PUE) of potato varieties propagated from apical rooted cuttings. Experiments were conducted at Egerton University, Njoro and Kenya Agricultural and Livestock Research organization, Molo, in a split plot arrangement in randomized complete block design with three replicates. Main plot factors were four potato varieties...

Standard heterosis and heterotic grouping of highland adapted maize (Zea Mays L.) inbred lines in Ethiopia

The current study was initiated to estimate the magnitude of standard heterosis for grain yield and yield related traits in a line x tester hybrids and to classify the inbred lines into different heterotic groups. Fifty entries consisting of 48 testcrosses developed from 12 inbred lines and 4 testers using line x tester design and two commercial check hybrids used in the study. The experiment was conducted using alpha...

Genetic variability and correlation of agronomic and malt quality traits in Ethiopian sorghum [Sorghum bicolor (L.) Moench] landraces at Sheraro, Northern Ethiopia

Sorghum (Sorghum bicolor (L.) Moench) is a major cereal crop, grown in a wide range of agro-ecology. However, in Ethiopia there are very few high yielding improved sorghum varieties for malting purpose. A field experiment was conducted at Sheraro, sub-site of Mytseberi Agricultural Research Center during the 2017 cropping season. The objectives of the study were to identify sorghum landraces with high grain yield, study...
