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 ...
Sowing density rather than row spacing influences chia radiation use and yield
(Wiley, 2022-10)
Chia (Salvia hispanica L.) production worldwide has been encouraged due to its high essential fatty acid content that is effective for reducing cardiovascular affections. However, few studies have assessed the sowing density ...
Cultivars of early soybeans subjected to cross-sowing in sowing populations
(2018-01-01)
Cross sowing is a little studied technique which may contribute to increase productivity. The objective of this study is to evaluate the effects of cross-sowing on population arrangements of early soybean cultivars with ...
Sowing operation direction and population densities in corn growing
(Univ Federal Campina Grande, 2019-03-01)
Among the factors that may influence corn yield are sowing operation direction and plant population, since they alter the shade index between crop rows, and consequently the efficiency of interception of the photosynthetically ...
Adubação nitrogenada e densidade de semeadura em soja
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2010-02-19)
In cultivars with a cycle shorter than 120 days it is known that there is a relationship between the speed of canopy closure and the grain yield. Aiming at a better initial growing and consequently a quickest canopy closure ...
Physical properties of Oxisol under conventional corn cultivation and no-till management systems
(2019-03-01)
Searches for soil management systems that aim at maintaining soil quality are fundamental, along with sustainable agricultural and farming management. Thus, the aim of the present research was to assess soil parameters ...
Effect of seed vigor and sowing densities on the yield and physiological potential of wheat seeds
(Abrates-assoc Brasileira Technologia Sementes, 2021-01-01)
Initial seed vigor and sowing density interact in establishment of plants in the field, and can thus affect expression of the plasticity of the wheat crop and the yield and physiological quality of the seeds produced. The ...
Breeding potential of maize composite Isanao VF1 in small spacing in the second growing season
(Brazilian Soc Plant Breeding, 2008-03-01)
The purpose of this study was to verify the breeding potential of the maize composite Isanao VF1 in the second growing season. One hundred and fifty half-sib progenies were evaluated of spacing of 0.45 m, densities of ...
Forage mass production and grazing loss of sorghum hybrid in response to the density of the sowing and the spacing between planting lines
(2011-07-01)
The objective of this experiment was to evaluate dry matter yield and loss of grazing due to animal trampling in response to sowing density and spacing between lines in the planting. Sorghum hybrid 1P400 was submitted to ...
