Economics of wheat and canola cropping systems for Oklahoma.

摘要

A crop rotation that includes winter wheat and winter canola may enable producers in the region to better manage weeds and diseases, increase yields, and potentially increase net returns. The first objective is to determine the costs and net returns of conventional tillage and no-till management farm practices for five wheat production systems. The second objective is to determine the breakeven yield for canola for a given expected wheat price, wheat yield, and canola price, under a conventional tillage system. Conventional-till and no-till management practices were examined for five alternatives: wheat seeded in (a) early September for forage-only, (b) early September for forage-only with foxtail millet seeded as a summer forage double crop, (c) early September for dual-purpose (forage plus grain), (d) late September for dual-purpose (forage plus grain), and (e) mid October for grain-only.; The conventionally tilled early September wheat planted for forage plus grain was the most economical of all production systems with a net return to land, labor, and management of {dollar}78.13 per acre.
