Reduced-tillage, cover crop intensive production systems have several important potential benefits for sweet corn growers including: fuel and labor savings; reduced equipment wear and tear; more timely planting under wet conditions; and improvements in soil physical, chemical and biological properties. Since sweet corn is an important rotational crop for many high value vegetables, improvements...

The Response of Morphological and Physiological Traits Grain Yield Corn to Planting Method Sugarcane Residue Compost

This study investigated the chemical composition and ruminal degradability of corn stover in three maize-planting regions in Qiqihaer, Heilongjiang Province, China. The whole stover was separated into seven morphological fractions, i.e., leaf blade, leaf sheath, stem rind, stem pith, stem node, ear husk, and corn tassel. The assessment of nutritive value of corn stover and its fractions was per...

Densities of the root-knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood,were compared following summer crops of tropical corn (Zea mays L.) and sorghum (Sorghum bicolorL.) at several locations in north Florida. Densities of M. incognita remained low soil) following the sorghum cultivars DeKalb FS25E and DeKalh BR64 and the sorghum­ sudangrass (S. sudanense [Piper] Stapf) hybrid D...

Conservation practices are implemented on farm fields in the USA through Farm Bill programs; however, there is a need for greater verification that these practices provide environmental benefits (e.g., water quality). This study was conducted to assess the impact of Farm Bill eligible conservation practices on soluble P (SP) and total P (TP) losses from four fields that were monitored between 2...

The population dynamics and damage potential of an undescribed species of Belonolaimus were investigated for 2 years in a naturally infested commercial corn field in southwestern Kansas and for a third year in a field microplot study. Population trends and vertical distribution of nematode life-stages were monitored and relationships between corn yields and initial or midseason nematode populat...

In this research effects of active toothed coulter on planter penetration in semi-dried soils covered with previous wheat (Triticum aestivum) residue was studied. Therefore, effects of three levels of speed ratio (coulter peripheral speed/tractor forward speed; 1.22, 2, 3) at two previous residue levels (baled and non-baled) and two modes of planter attachment (with and without row cleaner) on ...

in order to examine of the weed damage on corn and determination of the most suitable index for corn (zea mays l.) yield reduction in field condition and multi-species weed competition, an experiment as an interval mapping was carried out in the researching field of mashhad university during 2008-2009. treatments were complete control (pre-planting treflan and hand weeding), no control (no herb...
