The breadth and focus of the methyl bromide alternatives research program in Florida is not limited exclusively to evaluation of chemical combination treatment regimes. The Florida program also encompasses an evaluation of a diversity of nonchemical tactics. Some of the nonchemical alternatives evaluated include: 1) Cover crops 7) Pest Resistant Crop Varieties 2) Organic Amendments 8) Solarizat...

Sustainable soil and crop management practices that reduce soil erosion and nitrogen (N) leaching, conserve soil organic matter, and optimize otton and sorghum yields still remain a challenge. We examined the influence of three tillage practices (no-till, strip till and chisel till), four cover rops {legume [hairy vetch (Vicia villosa Roth)], nonlegume [rye (Secaele cereale L.)], vetch/rye bicu...

The photosynthetic leaf area may be influenced by soil texture. The objective of this experiment was to evaluate photosynthetic leaf area under different soil textures, based on soil electric conductivity (EC) measurements, tillage systems, and N rates in dryland corn (Zea mays L.) from 2007 to 2009. A commercially available soil electric conductivity (EC) measurement system (Veris Technologies...

The issue of reducing tillage resistance and lowering energy consumption has become increasingly relevant. Strip a positive impact on soil protection reduction. This study analysed the components rotary blades their relationship with operating parameters developed mathematical between (power fuel consumption). We summarised into three parts: air resistance, lateral rotational friction (divided ...

Re®nements of high residue cropping practices are needed to provide crop producers viable systems that are both economically and environmentally sound. Several tillage treatments in combination with row-placed fertilizer were evaluated in a 3 year study on maize (Zea mays L.) on a Luvic Phaeozem in southern Wisconsin, USA. Tillage treatments included fall chisel, fall and spring in-row residue ...

applying a suitable tillage method is vital to chickpea production in dryland conditions. hence, eight tillage methods were studied using strip plots in a randomized complete block design with three replications over three years at the dryland agricultural research institute in maragheh, iran. the amount of rainfall in the three years of the study were 202, 264 and 203 mm, respectively, which w...

Agricultural ecosystems have been viewed with the potential to sequester atmospheric carbon dioxide (CO2) by increasing soil organic carbon (SOC) through reduced tillage and cover cropping practices. There remains considerable uncertainty, however, regarding the carbon (C) sink/source potential of these systems and few studies have examined C dynamics in conjunction with other important greenho...
