to investigate the changes in yield and yield components of dry land wheat (triticum aestivum l. cv agosta), under the influence of residue and nitrogen levels and different tillage practices, a field experiment was conducted during the 2006-2007 growing season, in the agricultural research station of the college of agriculture, shiraz university, iran. the experiment was designed as a split-sp...

To study Assessing the impact of tillage practices on soil carbon losses dependents it is necessary to describe the temporal variability of soil CO2 emission after tillage. It has been argued that large amounts of CO2 emitted after tillage may serve as an indicator for longer-term changes in soil carbon stocks. Here we present a two-step function model based on soil temperature and soil moistur...

Snow and ice removal and clearing roadways after a winter storm account for major portion of roadway agencies located in snowy region’s maintenance budget. With the decreasing funds and increasing demand from the motoring public for mobility, roadway agencies are continuously looking for new innovative approaches for winter maintenance operations. One of the main focus of these approaches inclu...

Soil micro-food webs play an essential role in maintaining or improving the stability of agricultural soils, and they can be influenced by tillage. However, little is known with respect to soil microbial faunal communities their relationships shaped long-term tillage practices. The goal this study was investigate impact 38 years no-tillage (NT), subsoil (ST), moldboard plow (MP), rotary ridge (...

Livestock development in rainfed areas is slower due to the inadequate supply of nutritious fodder. Mono-cropping systems also have a negative impact on forage yield and nutrition as cereals are deficient protein. Hence, there dire need grow with legumes improve quality. Therefore, two-year field study was undertaken evaluate winter cereal–legume their mixtures viz. oats (cv. PD2-LV65), barley ...

An innovative task learning system called PLOW (Procedure Learning On the Web) lets end-users teach procedural tasks to automate their various web activities. Deep natural understanding and mixed-initiative interaction in PLOW makes the teaching process very natural and intuitive while producing efficient/workable procedures.

Abstract The process of smooth plowing with the turnover layers within its own furrow is characterized by high energy costs due to interaction plow body and in conditions blocked cutting. purpose research substantiate type second-rear frontal plow. proposed front for contains twin screw housings, first-row colliders, rear right- left-turning second-row colliders. Screw housings are equipped mir...

Abstract This paper reviews and analyzes the impact of residue burning on environment human health, influence ex-situ in-situ management reducing pollution improving soil crop yield, farmers’ economic benefits. Paddy is cultivated 43.8 Mha in India, producing 118.43 Mt grain an estimated 165.8 straw. Burning most common practice for managing rice residues mainly due to its simplicity, low cost,...

The ARS Root Zone Water Quality Model (RZWQM ver. 3.25) was used to simulate the effect of field measured macroporosity on atrazine transport to subsurface drain lines. Field data on atrazine concentrations in subsurface drain flow from corn fields, for modified no-till (mNT) and moldboard plow (MP) systems, were used to evaluate the performance of the RZWQM for the growing seasons of 1990, 199...
