| Abstract | ||
| An experiment under plastic house was conducted during season 2000-2001 in a loam texture soil Typic Torrifluvent to study the effect of levels and methods of triple super phosphate fertilizer 20% P and potassium sulfate fertilizer 41% K as P- and K- sources on growth and yield of tomato lycopersicon esculentum Mill, Carmello cultivar at the College of Agriculture- Univ. of Baghdad- Abu-Ghraib. A factorial experiment in RCBD included two methods of application: soil application an foliar application. Four levels for each method S1O + O1S2 75+100, S3 150-200, S4 225-300 (P+K).ha-1 were applied to soil, half soil application fertilizer was carried out in band beside plants after 30 days of transplanting, whereas the second half after 60 days planting. The foliar spray of fertilizer was started 66 days after planting and repeated every 30 days five times. F1 0+0, F2 7.5+10, F3 15-20, F4 22.5+30 (P+K) kg.ha-1 were applied in foliar applications with five consecutive time. All treatments received 1000kg N.ha-1. Urea 46% as N-source was used. Results showed that the combination treatment S3F3: 150-200 (P+K)kg.ha-1 added to soil +15+20 (P+K) kg.ha-1 as foliar had significant data in most growth characters, yield and P+K concentration in plants compared to percent of fertilizer efficiency for yield, fertilizer use efficiency, average fruit weight, P, K % in plant leaves, early yield and total yield were 51%, 8.6%, 29%, 40.9%, 36.1%, 50.2% and 50.0% respectively for the above mentioned characters compared to control treatment S1F1. It was concluded that the use of foliar and soil application together was important to get better yield of tomato. | ||
