Dynamics of Herbicidal Potential: Effects of Two Bacterial Species and Five Aqueous Plant Extracts on Yield and Yield Components of Rice (Oryza sativa L.) and Surof (Echinochloa crus-galli L.)
Journal Title: Journal of Soil, Plant and Environment - Year 2023, Vol 2, Issue 1
Abstract
This research aimed of investigate the effects of foliar applications using different levels of herbicidal potential from two bacterial species and five aqueous plant extracts on the yield and yield components of Oryza sativa L. and Echinochloa crus-galli L. The study followed a split factorial design based on randomized complete block design (RCBD) with three factors and three replications during the 2017-2018 crop year. The primary treatments consisted of aqueous extracts from Sorghum, Broccoli, Nettle, Eucalyptus and Elderberry, as well as Streptomyces sp-albos containing thaxtomin, Xanthomonas campestris, and control s (without aqueous plant extracts and surfactant). The secondary factor involved foliar application treatments with varying levels of concentration, including zero (control), 5, 10, and 15 per thousand extracts and the third experimental factor included Oryza sativa L. and Echinochloa crus-galli L. The findings revealed that as the extract concentration increased, plant height, leaf area index (LAI), grain yield, biological yield, chlorophyll a, chlorophyll b, and total chlorophyll contents decreased. Conversely, grain starch content increased with higher extract concentrations, with the most pronounced effects observed at 15 per thousand extract concentration. It was also observed that the use of extracts led to reduced yield characteristics and components in both Oryza sativa L. and Echinochloa crus-galli L. Among the extracts, Elderberry extract exhibited the most significant negative impact.  Comparatively, Oryza sativa L. demonstrated higher plant height, LAI, grain yield, biological yield, harvest index, chlorophyll content, grain protein content, and grain starch content when compared to Echinochloa crus-galli L. The results suggested that various extracts, particularly Nettle, along with 15 per thousand concentrations of Elderberry and Nettle extracts, hold potential for controlling Echinochloa crus-galli L. during the germination stage under field conditions.
