However, soils with good organic matter content having high water holding capacity with neutral pH are considered good for higher productivity. Being a sensitive crop to moisture stress particularly excess soil moisture and salinity stresses; it is desirable to avoid low lying fields having poor drainage and also the field having higher salinity.
Therefore, the fields having provision of proper drainage should be selected for cultivation of maize. AICRP organizes interdisciplinary, interinstitutional, co-operative and systematic testing of newly developed cultivars of both public and private sectors for different agro-climatic zones of the country. The project resulted in refining efforts in varietal improvement.

Identification of early and extra-early maturing tropical maize inbred lines resistant to Exserohilum turcicum in sub-Saharan Africa Badu-Apraku, B. When they mapped out the genetic connections between the specimens, the researchers discovered several distinct lineages, each with their own unique relationship to teosinte. Most significantly, the results revealed that although maize domestication began with a single large gene pool in Mexico, the grain was carried elsewhere before the domestication process was complete.
The partially domesticated maize seems to have landed in the southwest Amazon, which was already a hotspot for the domestication of other plants, including rice, squash and cassava. Kistler theorizes that maize was adopted into farming practices there, giving the domestication process a chance to pick up where it left off. It is possible, though not certain, that maize in this new location evolved more quickly than maize in the center of domestication, which would explain why the 5,year-old cobs from the cave in Mexico appear to be in an intermediary phase of domestication at a time when maize was already being cultivated in the Amazon.
After incubating in the southwest Amazon for several thousand years, maize went on the move again, according to the study authors—this time to the eastern Amazon, where it grew amidst a general flourishing of agriculture that archaeologists have observed in the region. Another interesting discovery lay in the fact that modern maize from the Andes and southwestern Amazon is closely related to maize grown in eastern Brazil, which points to another movement eastward.
The amount of maize grown in the UK has rocketed since the s. In there was around 20, acres of maize being farmed in Britain, by this had reached , acres. And there is no sign of this growth slowing down. You must be logged in to post a comment.
