Weed control in seedling alfalfa
California Agriculture, 1967 Pre-emergence herbicides offer the advantage of reducing early competition in seedling alfalfa stands. The disadvantages of present pre-emergence herbicides is that they have to be incorporated, which adds extra expense, and they do not control all of ...

Irrigation and Drainage, EarlyView.ABSTRACT There is limited integrated evaluation of nitrogen (N) and irrigation management strategies for improving maize yield and productivity using crop models. The effects of N and irrigation on maize yield and productivity under centre pivot (CPI) and subsurface drip irrigation (SDI) using the CERES‐Maize model were investigated. N treatments were (

Economic evaluation of a weed-activated sprayer for herbicide application to patchy weed populations [PDF]
Spatial distribution of weeds in a crop is patchy. Traditional boom sprayers waste herbicide by applying it to areas where weed density is already low.

Weed control studies in strawberries
California Agriculture, 1967 Present-day strawberry culture demands a field clean of weeds. This is particularly true in some areas of California where the practice of covering beds with a clear polyethylene film for several months (beginning usually in January or February) creates ...

Irrigation and Drainage, EarlyView.ABSTRACT Irrigation can strongly influence agricultural productivity and sustainability. While sensor‐based irrigation has the potential to improve yield, reduce input costs and enhance resource‐use efficiency, its adoption in commercial agriculture remains limited.

California Agriculture, 1969 Under the conditions of the experiments reported, trifluralin, nitralin, DCPA, bensulide and two commercially unavailable compounds were safest on young grape vines. Fair to good weed control was obtained at safe rates except where resistant weed species

Journal of the Agricultural and Applied Economics Association, EarlyView.Abstract Greenhouse gas emissions from crop production contribute to anthropogenic climate change, while agricultural soils also sequester atmospheric carbon. Direct measurement of soil organic carbon (SOC) is limited by high sampling costs and the vast spatial extent of farmland.
