Why are second-generation transgenic crops not yet available in the market?
(Oxford University Press, 2020-08)
Recent studies predict that global food demand of major grain crops will not be accompanied by the required increase in yield (Hall and Richards, 2013). Additionally, current figures estimate that the impact of climate ...
Phosphorus and potassium balance in soil under crop rotation and fertilization
(Universidade Estadual de Londrina (UEL), 2012-01-01)
The use of crop rotation and manure application can provide sustainability for an agricultural production system by improving soil quality and increasing nutrient use efficiency. This study aimed to evaluate the effect of ...
Productivity and resource use in intensified cropping systems in the Rolling Pampa, Argentina
(Elsevier, 2015-04)
Increasing cropland productivity is critical to meet future global demand of food, fibers and biofuels. Recent innovations in grain crop management are aimed at designing more ecologically complex cropping systems by growing ...
Physical quality of an Oxisol under no-tillage subjected to different cropping systems
(Empresa Brasil Pesq Agropec, 2016-09-01)
