could be optimized using modified NT systems (including ST) and starter fertilizer. In Iowa Mallarino et al. (1999) Utilizing conservation tillage practices and increasing fertilizer N found that ST frequently increased early growth but seluse efficiency for corn (Zea mays L.) are necessary for optimizing dom increased corn grain yields compared with NT. growers’ profits and for minimizing loss...

Soil organic C (SOC) and total N (TN) contents play a crucial role in sustaining agricultural production systems. Short-term ( 10-year) management effects on SOC and TN dynamics are often complex and variable. Three experiments were conducted to evaluate short-term tillage and cropping system effects on SOC and TN within the 0–30 cm soil depth across Iowa. The first experiment with no-tillage a...

this experiment was arranged as a strip-plot on the base of a completely randomized block design with three replications to study the effect of tillage (whether in day or night or in day by light-proof cover) and application of reduced dosage of imazethapyr and trifluralin on weed control, yield and yield components of chickpea. main plots consisted of tillage methods and subplots consisted of ...

The dynamics of soil moisture and its temperature is an important criterion for evaluating tillage technology in terms achieving plant production stability. Understanding changes depending on rainfall air necessary to develop application models agriculture 4.0. A hypothesis was adopted assuming that the thermal properties will depend cultivation. Hence, aim research learn during a growing seaso...

Conservation tillage systems provide optimum conditions to reduce soil erosion and increase surface soil organic matter. This experiment was established with the longterm goal of developing conservation tillage systems that use either chemical inputs to produce vegetables and control pests, or legume cover crops, biological pesticides, and tillage to provide plant nutrition and control pests. T...

We measured growth and development variables on single soybean [Glycin max (L.) Merr.] plants under five management strategies in the upper Midwestern USA. Plants grown under different management strategies differed significantly in their geometric structures, and were classified into their proper categories with 75 to 100% correct classification, based mainly on differences in their fractal di...
