Corn response to subsoiling and nematicide application.
A 2-year field study evaluated the influence of subsoiling and nematicide application, alone and in combination, on the growth and yield of field corn in a sandy soil in north-central Florida. The field had a 25-30-cm-deep tillage pan (plowpan) and was infested with Belonolaimus longicaudatus, Hoplolaimus galeatus, Trichodorus christei, and Pratylenchus spp. Subsoiling increased corn yield both...
متن کاملInteraction of four soybean cultivars with subsoiling and a nematicide.
Yields of four soybean, Glycine max, cultivars were increased with subsoiling under the row and application of the nematicide, DBCP i 1,2-dibromo-3-chloropropane) in Tiflon sandy loam heavily infested with the root-knot nematode Meloidogyne incognita. These cultivars represent four maturity groups: very early (V), "Essex', early (VI), "Davis': medium (VII), 'Ransom'; and late (VIII), ' Hutton '...
متن کاملA Portable Tillage Profiler for Measuring Subsoiling Disruption
A portable tillage profiler (PTP) was constructed using a laser distance sensor, a linear actuator, a portable PC, and a lightweight aluminum frame that can quickly and accurately measure aboveground and belowground soil disruption caused by tillage. A laboratory experiment was conducted that determined that soil color did not detrimentally affect the PTP, with expected vertical errors of 2.3 m...
متن کاملYield Response of Spring Maize to Inter-Row Subsoiling and Soil Water Deficit in Northern China
BACKGROUND Long-term tillage has been shown to induce water stress episode during crop growth period due to low water retention capacity. It is unclear whether integrated water conservation tillage systems, such asspringdeepinter-row subsoiling with annual or biennial repetitions, can be developed to alleviate this issue while improve crop productivity. METHODS Experimentswere carried out in ...
متن کاملInfluence of Altitude Atmospheric Pressure on Octane Requirement (RESEARCH NOTE).
The normal specifications of motor gasolines as well as their combustion characteristics in internal combustion engines are reviewed in this paper. The effective factors influencing the fuel performance, such as the molecular structure of the fuel constituents, the operating conditions and the atmospheric pressure and temperature are also discussed. A relationship between the optimum octane num...
