ASSESSMENT OF JEDDAH PARKS HEALTH STATUS BY Cyperus rotundus AND SOIL ANALYSIS UNDER WASTE WATER IRRIGATION Planta Daninha
EL-NAKHLAWY,F.S.; AL-SHAREEF,A.R.; IHSAN,M.Z..
ABSTRACT To investigate the health status of public parks in Jeddah city, a field survey was conducted based on the Cyperus rotundus weed and soil analysis of wastewater-irrigated parks during 2012. The city was divided into five different locations (North, South, East, West and Middle) and five parks were randomly sampled from each location; thus, the total number of sampled parks were twenty five. Toxic metals concentration were analyzed in the soil and in the plants while bacterial count was determined from the weed leaves. All studied toxic metals have significantly crossed the European Union safety limits for plant samples, while soil samples were just beyond the limit. The highest concentration was perceived for Lead (133-232 mg kg-1) and was...

WATER USE EFFICIENCY, GROWTH AND YIELD OF WHEAT CULTIVATED UNDER COMPETITION WITH Setaria Planta Daninha
IHSAN,M.Z.; EL-NAKHLAWY,F.S.; ISMAIL,S.M..
ABSTRACT Understanding the critical period of weed competition is indispensable in the development of an effective weed management program in field crops. Current experiment was planned to evaluate the critical growth period ofSetaria and level of yield losses associated with delay in weeding in rain-fed drip irrigated wheat production system of Saudi Arabia. Field experiment was conducted to evaluate the effect of weeding interval (07-21, 14-28, 21-35, 28-42 and 35-49 days after sowing) and drought stress (75% and 50% of field capacity) on Setaria growth, wheat yield and water use efficiency. Season long weedy check and wellwatered (100% FC) plots were also maintained for comparison. Weeding interval and drought stress significantly (p ≤ 0.05) affected...

Estimation of weed dry biomass and grain yield as a function of growth and yield traits under allelopathic weed management in maize Planta Daninha
MAHMOOD,A.; KHALIQ,A.; IHSAN,M.Z.; NAEEM,M.; DAUR,I.; MATLOOB,A.; EL-NAKHLAWY,F.S..
Growing concerns about toxicity and development of resistance against synthetic herbicides have demanded looking for alternative weed management approaches. Allelopathy has gained sufficient support and potential for sustainable weed management. Aqueous extracts of six plant species (sunflower, rice, mulberry, maize, brassica and sorghum) in different combinations alone or in mixture with 75% reduced dose of herbicides were evaluated for two consecutive years under field conditions. A weedy check and S-metolachlor with atrazine (pre emergence) and atrazine alone (post emergence) at recommended rates was included for comparison. Weed dynamics, maize growth indices and yield estimation were done by following standard procedures. All aqueous plant extract...

Allelopathic Effects of Different Plant Water Extracts on Yield and Weeds of Wheat Planta Daninha
NAEEM,M.; CHEEMA,Z.A.; IHSAN,M.Z.; HUSSAIN,Y.; MAZARI,A.; ABBAS,H.T..
ABSTRACT: Use of synthetic herbicides to control weeds poses serious threats to sustainable agricultural production around the globe. The phytotoxic effect of different plant water extracts (i.e., sorghum, sunflower and mulberry) against weeds has been previously studied; however, their combined effects at different rates are yet to be explored. In this study, mixtures of allelopathic water extracts of sorghum + sunflower and sorghum + sunflower + mulberry were sprayed each at 12, 15, 18 and 21 L ha-1 at 40 and 55 days after sowing in wheat to control wild oats (Avena fatua), little seed canary grass (Phalaris minor), lamb’s quarters (Chenopodium album) and swine cress (Coronopus didymus). A synthetic herbicide Affinity 50 WP (Carfentrazone-ethyl 0.75% +...

Trianthema portulacastrum and Cyperus rotundus Interference in Maize and Application of Allelopathic Crop Extracts for Their Effective Management1 Planta Daninha
NAEEM,M.; MAHMOOD,A.; IHSAN,M.Z.; DAUR,I.; HUSSAIN,S.; ASLAM,Z.; ZAMANAN,S.A..
ABSTRACT Horse purslane (Trianthema portulacastrum) and purple nutsedge (Cyperus rotundus) are two noxious C4 weeds of maize crop causing extensive yield losses. A two years field experiment was performed to estimate interference of T. portulacastrum and C. rotundus and to evaluate the role of allelopathic water extracts for effective weed management in maize. Five plant water extracts in ten binary combinations were foliar applied in triplicated randomized complete block design. Plots treated with commercial herbicide atrazine and weedy check (control), were also maintained for comparison. The highest density of both weed species was observed at 45 days after sowing (DAS) while weed dry biomass was higher at 60 DAS. Binary combination of sorghum-sunflower...
