Response of Snap Bean Plants to some Treatments under Temperature Stress Conditions

Abstract

to study the effect of soil applications, i.e., seaweed (5 gm/100 L) (feldspar 75 kg/fed.), foliar applications, i.e., chitosan (175 ppm), yeast extract (20 ml/l), proline (50 ppm), salysilic acid (150 ppm), ascorbic acid (200 ppm), potassium silicate (100 ppm), ATP (0.03 gm/l), Royal jelly (0.1 g/l), fulvic acid (0.25 g/l) and citric acid (0.3 g/l). on growth, yield and chemical composition on snap bean cv. Giza 6. The obtained results revealed that, summer season data gave higher value of growth, yield and chemical composition of plants compared with the winter seasons date. Soil addition with seaweed at 5gm/l and spraying chitosan at 175 ppm gave the highest growth, yield and chemical components of bean plants, followed by yeast extract at 20 ml/l, and proline at 50 ppm. Sowing snap bean cv. Giza 6 in 20 th May with adding seaweed as a soil at 5 gm/l and spraying with chitosan at 175 ppm introduced the best interaction with respect to growth, yield and chemical composition of plant. From the obtained results it could be recommended that sowing snap bean cv. Giza 6 in 20 th May with seaweed extract addition at 5g/100 L. and spraying with chitosan at 175 ppm and/or yeast extract at 20 ml/l, and/or proline at 50 ppm improved growth, yield and chemical composition of snap bean growing at summer season.
