Weed control in processing tomatoes

open access: yesCalifornia Agriculture, 1977
High yields in processing tomatoes depend on a great many factors, not the least of which is good weed control. Weeds compete severely with the tomato, primarily for water and light, and interfere with mechanical harvest.

The influence of soil tillage systems and weed control methods on weed infestation of potato (Solanum tuberosum L.)

open access: yesActa Agrobotanica, 2012
A field experiment was conducted in the years 2002- 2004 at the Zawady Agricultural Experimental Station (52o06' N; 22o06' E), belonging to the University of Podlasie in Siedlce, Poland. The investigated factors were two soil tillage systems (traditional

Concurrent Response of Soybean to Fixed (Full and Limited) and Variable Rate Irrigation Management in Three Soil Types: II. Growth, Yield, Evapotranspiration and Water Productivity

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Soybean growth, yield, crop evapotranspiration (ETc) and crop water use efficiency (CWUE or crop water productivity, CWP) under different irrigation levels in three different soil types in the same field were investigated concurrently. Treatments in each soil type were: (i) variable rate irrigation (VRI), (ii) fixed rate full irrigation (FR‐1″)

Weed control in cole crops

open access: yesCalifornia Agriculture, 1968
Of the many herbicides tested recently in California cole crops, FW-925 (TOK-E–25) —applied pre-emergence without incorporation—had the largest and most consistent margin of safety for direct-seeded cole crops.

Effect of weed control methods on growth of five temperate agroforestry tree species in Saskatchewan

open access: yesThe Forestry Chronicle, 2017
Most tree species in agroforestry plantings are intolerant to vegetative competition and sites must be intensively cultivated to eliminate weeds. Many studies have been conducted to investigate what factors limit seedling growth because of the presence ...

Concurrent Response of Soybean to Fixed‐ (Full and Limited) and Variable‐Rate Irrigation Management in Three Soil Types: I. Soil Water Dynamics

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT This research investigated soybean soil water dynamics under different irrigation levels in three different soil types in the same field concurrently. Treatments imposed in each soil type were: (i) variable‐rate irrigation (VRI), (ii) fixed‐rate full irrigation (FRI‐1″ or FRI‐25.4 mm) and (iii) fixed‐rate limited irrigation (FRI‐0.75″ or FRI ...

Weed control in seedling alfalfa

open access: yesCalifornia 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 ...

Weed flora, yield losses and weed control in cotton crop

open access: yesJulius-Kühn-Archiv, 2016
Cotton (Gossypium spp.) is the most important fiber crop of world and provides fiber, oil, and animals meals. Weeds interfere with the growth activities of cotton plants and compete with it for resources.
