RESPONSE OF GROWTH AND PRODUCTIVITY OF TOMATO FOR SPRAYING WITH BOTANICAL EXTRACTS AND CHEMICAL AND ORGANIC FERTILIZER UNDER GREENHOUSE CONDITIONS

Abstract

Two experiments were conducted in a plastic house at AL-Latifia Research Station, Agricultural Research Directorate, Plant Breeding and Improvement Center during the spring season of 2018 to study the response of growth and productivity of tomatoes for spraying with botanical extracts (Roselle and Fenugreek) with concentrations (0,2,4g.L-1 and fertilization experience included (chemical fertilizer recommendation, poultry residues, humic acid liquid, and powder).  Two Experiments' within Randomized Complete Block Design (R.C.B.D) were adopted. The first experiment results showed the superiority of the treatment of spraying with Roselle extract (4 g.L-1) significantly of increasing the leaf area, the content of chlorophyll, and the number of fruit 327.10 dcm2 47.88   SPAD and51.89 respectively, while were 221.40 dcm2,39.90   SPAD and 40.57 respectively in the control treatment. And there is a non-significant influence of the source of botanical extracts on the weight and size of fruits, Moreover, the treatment of spraying with Roselle extract (2 g.L-1) showed a significant increase in the plant yield and total yield of 6.02, 3765.00 kg respectively compared with control treatment 3.90, 2465.00 kg respectively. While the second experiment results showed, that the treatment of chemical fertilizer showed significant increase in the plant yield and total yield which were 8.63 and 5392.00 kg respectively, and non-difference significantly with the treatment of manure of poultry, which was 8.61 and 5383.00 kg respectively compared with the treatment of control that was 4.69 and 2929.00 kg respectively
