Weed Control, Growth, Nodulation, Quality and Storability of Peas as Affected by Pre- and Postemergence Herbicides

Abstract

Weeds represent a major constraint for successful pea cultivation, resulting in loss of green pea yield and quality. Two field experiments were carried out during the winter seasons of 2018/2019 and 2019/2020. The objectives of the current study were to evaluate the efficacy of pendimethalin, butralin, fluazifop butyl, bentazon, and hoeing on weed control, and their impact on pea growth, nodule formation, yield, quality, and storability. The results indicated that hoeing and fluazifop butyl were the most effective treatments for weed control in terms of the lowest values of total weed dry weight. The bentazon and fluazifop butyl herbicides didn’t affect active nodules number, plant height, plant weight, root length, or number of leaves and branches. Additionally, bentazon and hoeing resulted in the highest total yield per plant and protein content. Butralin and pendimetalin achieved the lowest yield, and butralin also resulted in the lowest plant height and weight. Bentazon-treated peas had the highest chemical compositions in terms of chlorophyll, carotenoids, total sugar, and vitamin C contents in pea pods at harvest and during cold storage at 4 °C and 95 RH for 45 days. No detectable residues of the four herbicides under study were detected in green pods, suggesting that pods can be safely consumed at the time of harvesting. It can be concluded that nodules formation in pea was not affected significantly by the application of the tested herbicides, except pendimethalin and butralin. Furthermore, bentazon had a positive impact on nodules formation and pods quality and could be used effectively for controlling the broadleaf weeds, and it was simultaneously a selective and safe herbicide in pea cultivation.

A Controlled-Release Nanofertilizer Improves Tomato Growth and Minimizes Nitrogen Consumption

“…The acidity percent was calculated from the titration data as a percentage of citric acid in the juice [ 19 ]. Vitamin C was analyzed based on a titration method as described by Abdallah et al [ 20 ]. Briefly, 10 g fresh fruits were homogenized with 90 mL of oxalic acid (6%) for 10 min., then 2,6-dichlorophenol indophenol was used to titrate 25 mL of filtrated solution.…”

Pre-Harvest Application of Salicylic Acid, Abscisic Acid, and Methyl Jasmonate Conserve Bioactive Compounds of Strawberry Fruits during Refrigerated Storage

“…The amount of ascorbic acid in the fruit was measured in mg/100 g FW. Total phenolic compounds (TPC) in the fruit juice extract were quantified using the Folin-Ciocalteu reagent and standard gallic acid, as reported previously [29], with minor modifications. In brief, strawberry aliquot puree was centrifuged at 8000× g at 25 • C for 20 min.…”

Effectiveness and Selectivity of Pre- and Post-Emergence Herbicides for Weed Control in Grain Legumes

“…In most grain legume cropping systems, chemical control is mostly preferred by farmers since herbicides are a more reliable, effective, and profitable method of controlling different weed species [ 19 ]. In grain legumes, it is well documented that the most important type of herbicide is the pre-emergence (PRE) one [ 20 ].…”
