Impacts of honeybee density on crop yield: A meta-analysis
(Wiley Blackwell Publishing, Inc, 2019-02-03)
1. There is increasing recognition that pollination deficits are limiting crop yields world-wide. However, management strategies for optimal insect pollination are still unclear for most crops. Current management focuses ...
Root growth and nutrient accumulation in cover crops as affected by soil compaction
(2002-03-25)
Crop rotation using cover crops with vigorous root systems may be a tool to manage soils with some degree of compaction. Root and shoot growth as well as nutrient accumulation by summer species suitable for crop rotation ...

Physical quality of an Oxisol under no-tillage subjected to different cropping systems
(Empresa Brasil Pesq Agropec, 2016-09-01)
The objective of this work was to evaluate the physical quality of an Oxisol under no-tillage subjected to different crop rotations and crop sequences. The experiment was carried out in a clayey Oxisol, during six years, ...
Effects of density and sowing pattern on weed suppression and grain yield in three varieties of maize under high weed pressure
We tested the hypothesis that improved weed suppression
by maize can be achieved through increased crop
density and spatial uniformity. Field experiments on
three varieties of maize sown at three densities (5, 7
and ...
Quality control to seeding systems and densities in peanut crop
(2014-01-01)
The mechanisation of peanut cultivation has evolved over the years, but there are still obstacles that affect the quality of mechanised operations. Among these, sowing is essential for ensuring an adequate plant stand and ...
