| Abstract | ||
| An experiment was conducted in Kufa Technical Institute for the growing season of 2008/2009 in unheated plastic house .This study included 8 interaction treatments, two tomato cultivars i-e Dombito(V1) and MonteCarlo(V2) with four spraying treatments(5times),the first on transplants ten days before transplanting,the second 30 days after transplanting and three spraying with an intervals of 14 days from second spraying.The treatments were : 1. water spraying only(control),(T1). 2. Mixture spraying of Fe +Zn +B with conc. of 1.5mg/L for each nutrient (T2). 3. Spraying with growth regulator(Atonik)with conc. of 15%,(T3). 4. Spraying with amixture of( Fe+Zn+B and Atonik),(T4). the aim was to study the effects of foliar spraying with micronutrients and growth regulator( Atonik) on Vegetative growth,yield and some chemical characteristics for the above two cultivars under unheated plastichouse conditions. Results showed that,the highest values of vegetative growth(plant haight,stem diameter,plant leaf number,plant leaf area and plant dry weight)were produced From the interacti of (V1) and (T4),which were(234.2cm.,2.81mm.,164.8,896.7cm2 and 92.8g),respectively. Meanwhile,the lowest values were,117.4cm.,1.38mm.,72.7leaf area and(8.33g) for plant height,stem diameter,plant leaf number,and plant dry weight,respectively were produced from control treatment and (V2). The highest yield value came from the interaction between (V2) and (T4),which produced 22.05/Ton/180 m2. The highest of fruits/plant and highest early yield producd from the interaction between (V1) and (T4) which reached 64.72 fruits and 3.21 kg/plant,respectively.The highest mean of fruit weight and highest yield/plant were 170.24 g.and 10.77 kg.respectively produced from the interaction of (V2) and (T4).compared with the lowest values for the above parameters that produced from (V2) and (T1). Treatment(T4)accompanied with the two cultivars for all studied chemical characteristics were signicantly affected vit.C.,total soluble solids and the percentage of fruit total acidity. | ||
