Effect of foliar application of different mixtures of chemical fertilizers and pesticides on growth and yield of tomato plant grown in desert region /Basrah

Abstract

An experiment was conducted during winter season of 2011/2012 at Al – Bourjesiah ExperimentalResearch Station. Zubair belong to Ministry of Agriculture include desert area southern of Iraq underplastic tunnels. The aim of was to study the effect of foliar application of some mixtures of chemicalfertilizers and pesticides on vegetative growth parameters, flowering and yield of hybrid tomato plant cv. "Hatouf " .The experiment included 26 factorial treatments resulting from the interaction between 13 foliarapplication of chemical fertilizers dissolved in water at average of 1.75 g/ l water to each of MAP. DAP andNPK and with two pesticides ( Match and Score) at concentration of 0.5 ml/l water alone or mixing withpesticides and two spraying times (Morning or night). Randomized Complete Block Design was used withthree replicates. Duncan's Multiple Range Test was used at probability of 5% to compare mean variations.Results can be summarized as follows:-Plants sprayed with Score + Match + NPK mixture gave a significant increase in number oflateral branch/ plant, dry weight/plant, total number of inflorescences/ plant, plant yield and total, while plants sprayedwith Score + Match + DAP mixture gave a significant increase in plant length (92.8 cm), whereas it haveno effect on leaves number/ plant. Time of spraying have no effect on all studied parameters. while theinteractions between the two factors have no effect on studied parameters except for the number oflateral branch/ plant. The highest number was 35.3 branch from treatment Score + Match + NPK mixturein the morning.Key Words: Tomato. foliar application
