Improvement in yield of bread wheat cultivars released in Ethiopia from 1949 to 1987
(African Crop Science Society, 1995)
Thirteen bread wheat ( Triticum aestivum check for this species in other resources L.) cultivars popular in the highlands of Ethiopia and representative of the period from 1949 to 1987 were studied for two cropping seasons ...
Genotype by environment interactions and agronomic performance of doubled haploids testcross maize (Zea mays L.) hybrids
In vivo production of maternal haploid plants and advancement in chromosome doubling technology has led to rapid production of doubled haploid homozygous lines. These in turn have boosted rapid advancement in most breeding ...
Response of maize (Zea mays L.) secondary growth parameters to conservation agriculture and conventional tillage systems in Zimbabwe
(Canadian Center of Science and Education, 2016)
Previous, research focused mainly on the effects of conservation agriculture (CA) and conventional practices (CP) on crop yield mostly. A study was conducted at five sites in Zimbabwe from 2012 to 2014 to investigate effects ...
Impact of conservation tillage in rice–based cropping systems on soil aggregation, carbon pools and nutrients
Tillage intensive cropping practices have deteriorated soil physical quality and decreased soil organic carbon (SOC) levels in rice–growing areas of South Asia. Consequently, crop productivity has declined over the years ...
