Tillage system is one of the main factors influencing growth and physiology wheat (Triticum aestivum L.), that eventually translates to high yield good kernel quality. The objectives this study were determine effects ridge (RT) flat tillage (FT) systems on (i) production spring wheat, (ii) root (iii) soil physical properties. Trials conducted at Kenya Agricultural Livestock Research Organizatio...

ing. The band control received a coulterknife pass without fertilizer. Soybean response to direct P application was evaluated in seven trials (Sites 1 through 7). The treatments were applied in the fall (October or November) after harvesting the previous corn crop and before soils had frozen. At the remaining seven trials (Sites 8 through 14), P was applied 1 year earlier (in the fall prior to ...

Accurate simulation of agricultural management effects on N loss in tile drainage is vitally important for understanding hypoxia in the Gulf of Mexico. An experimental study was initiated in 1978 at Nashua, Iowa of the USA to study long-term effects of tillage, crop rotation, and N management practices on subsurface drainage flow and associated N losses. The Root Zone Water Quality Model (RZWQM...

The purpose of this research is to study the effect deep loosening row spacings on physical properties soil and yield organic potatoes. Two variants cultivation were used in spacings: usual 25 cm deep. was carried out with a row-crop chisel cultivator. Its design developed at institute. Analysis data obtained as result experimental studies showed that had positive compaction both inter-row widt...

Carrot (Daucus carota L.) has historically been classified as a northern crop because it predominantly grows in the regions of Nigeria. Transportation harvested roots to south consequently resulted decay, shrinkage, loss due high temperature and long distant travels, cost produce etc. The objective was find out variety tillage method that will enhance production carrots Southeast Nigeria approp...

Abstract China is a huge agricultural country with rich straw resources. However, the problem to be solved urgently find means use crop effectively and reasonably. To study influence of no-tillage mulching measures on soil compactness organic matter, taking black test field in Gaojia Village, Lishu County, Jilin Province as research object, characteristics matter different tillage layers under ...

The effect of different tillage systems on the size distribution of aggregates and organic carbon distribution and storage in different size aggregates in a Hydragric Anthrosol were studied in a long-term experiment in Chongqing, China. The experiment included three tillage treatments: conventional tillage with rotation of rice and winter fallow (CT-r) system, no-till and ridge culture with rot...

The purpose of the study is to substantiate design scheme and parameters working bodies a combined machine for tillage sowing grain on sloping lands. authors have developed that performs technological operations tillage, sowing, ridge formation prevent water erosion. diagram given. basic principles methods classical mechanics, mathematical analysis, statistics were used in this study. Theoretic...

Recent developments in biofuel demand and the rapid adoption of modern transgenic hybrids are changing production systems towards more corn after corn, more intensive tillage, higher plant populations, and ever higher crop residue levels at harvest. Meeting society’s needs for food, feed, and fuel from grain corn, and in the future from corn stover, requires continued refinement of tillage syst...

Emphasis and interest in carbon (C) and nitrogen (N) storage (sequestration) in soils has greatly increased in the last few years, especially C with its’ potential to help alleviate or offset some of the negative effects of the increase in greenhouse gases in the atmosphere. Several questions still exist with regard to what management practices optimize C storage in the soil profile. A long-ter...
