In order to evaluate the effect of seed size, plant growth regulators and some chemical materials on seed vigour and seedling growth of rice (Oryza sativa L.) an experiment was conducted in 2015 at Laboratories of Agriculture and Marshes College, University of Thi-Qar. Factorial experiment in CRD was used with four replications in two factors. The first factor included three seed sizes (4.6-5.1, 5.2-5.7 and 5.8-6.3 mm). The second factor was seeds soaking treatments (KNO3 6 gl-1, CaCl2 20 gl-1, salicylic acid 20 mg l-1, cytokinin 40 mg l-1, gibberllic acid 400 mg l-1, ascorbic acid 40 mg l-1 and seeds soaked in distilled water). The results showed that the largest seed size influenced significantly and gave the higher averages of germinatio

Two factorial experiments were conducted .The first one was field experimental which was carried out at the one of  agricultural farms in Thi-Qar governorate – Nassiriyah district during the winter seasons of 2014 - 2015 and 2015 - 2016  .The second was carried out in the laboratories of Agriculture and Marshes Colle. , Univ. of Thi-Qar  . The aim was to investigate the effect of foliar application of seaweed extract on growth , yield and seeds vigour of four bread wheat cultivars . The design of field experiment was (RCBD) in factorial experiments with three replications in two factors .The first factor included four wheat cultivars ( Bohooth -22, Al-tahadi , IPA – 99 and Al-Rasheed )

This experiment was carried out at laboratories of Agriculture and Marshes College , University of Thi-Qar and at laboratories of agriculture  college , university of  Basra  during 2013 - 2014 . The aim of this study was to    identify the effect of the different seeding rates (80,100,120 and 140 kg.ha^-1)  on viability and quality characters of  four wheat cultivars ( Abu-Ghraib, IPA – 99 , Al-fatih and Al-Iraq ) seeds . Factorial experiments in CRD was used with four replication in two factors . The results showed that there were significant differences between two factors of study and their interaction. The seeds produced  from seeding rate 80 kg.ha^-1 gave th

This study was carried out in epidemically field with common reed (Phragmites communis Trin.) plants in the Nassiriah cityThiQur governorate ,during 2009/2010 to investigate the influence of plant growth regulator gibberellin (GA3)and cytokinin (CK) in increasing the efficacy of glyphosate and Fluazifop-butyl in common reed control . Factorial experiment in RCBD was used with three replications in tow Factors . Glyphosate 3500mg .l־¹ gave the higher mean of injury score of common reed and lower mean of common reed shoots , shoots dry weight and rhizome dry weight(3.59,22.01 shoot /0.5m² ,0.57Kg / 0.5m² and 250.50gm /0,5m² ),respectively. All plant growth regulators gaves the higher means of common reed shoots and rhizome dry weight com

A field experiment was carried out in one of the agricultural fields in Thi Qar governorate in Nasiriyah during the winter season 2017-2018 The aim was to investigate the effect of foliar application of seaweed extract on yield and quality of four varieties of broad bean .The design of field experiment was (RCBD) in factorial experiments with three replications in two factors. .The first factor included four broad bean cultivars (Luz de otono – Grano Violtto -local - Aquadols. ( The second factor included four sprayed extracts of the seaweed extract (1, 2, 3 and 4 g L -1) In addition to the comparison treatment in which the plants were sprayed with distilled water only. . The plants of the broad bean that were sprayed with seaweed extract

Two factorial experiments were conducted. One of them was laboratory experiment which was carried out at the Laboratory of Agriculture and Marshes College, University of Thi-Qar during laboratories of certification and test of seeds office in Thi-Qar governorate–Nassiriyah district during 2015. The other was conducted at the lath house with used the pots during spring season of 2016. The aim was to investigate the effect of soybean seeds priming before sowing on seed vigour and seedling growth characteristics under salinity stress. The design of Lab. experiment was (CRD) while for the other experiment was (RCBD) with four replications. Each experiment consisted of two factors. The first factor included seeds soaking treatments for 24 hour
