AbstractThe experiment was carried out during growing season (2016-2017) at station of greenhouses, AL-Muthanna university- collage of agriculture- second research station (Al-Bander) to study the response of introduced tomato cultivars to different concentrations of potassium under protected agriculture conditions. The research included three cultivars (Pusa ruby - Arka vikash- Arka Alok) and three levels of Potassium Fertilizer (90-180-270 kg/ha-1). The Randomized Complete Block Design with factorial experiment (RCBD) with three replicates. The results showed the superiority of Arka Alok variety over others in plant height 121.76 cm, fruit width 6.82 cm, fruit length 4.23 cm, average fruit weight 130.61g, leaf area 129.5 cm2, the yield per plant 2.16 kg. The potassium level (270 Kg/ha-1) was also significantly higher in plant height 118.79 cm, fruit width 5.477 cm, fruit length 3.536 cm, 84.60 g, leaf area 127.3 cm2, TSS 4.97 and chlorophyll content 406.89 mg.m2 and yield per plant 2.16 kg. While the interaction showed significant difference (Arka Alok × 270 Kg.ha-1) in fruit length was 4.24 cm, chlorophyll content was 374.91 mg. m2 and the yield per plant was 2.82 kg. plant-1.-1.
