Abstract Pot experiments were conducted under the green house conditions to study the response of two cultivars of wheat (Triticum aestivum cv. i.e Sakha 93 and Seds -1) to chicken manure as a soil treatment and amino acids as a foliar spray treatments on grain weight as well as the straw weight and yield components of macro nutrients (N, P, K, Ca, Mg and Na) and micro nutrients (Fe, Mn, and Zn) under irrigation with water of different salinities. Amino acids spray treatments included: non spraying (T1), Arginine (T2), Proline ’Pr’ (T3) and Proline +Glutarnic acid (Pr+G1) (T4), Humic acid ’HA’ Humic acid + Arginine 11A+Ar’ (T6) and Humic acid + Proline + Glutamic `11A+Pr+G1’ T7 [7 treatments]. Different levels of irrigation water salinity were also assessed. There were 3 different levels of salinity by diluting sea water with tap water. There was a ratio of 1:5 (8.29 dSm’) and a ratio of 1:3 (11.02 dSm-I) beside tap water itself (.59 dSm1) . Soil was taken from the 0-30 surface layer from El Nubaria Research Station. It was air dried, gently crushed and sieved through a 2 mm screen and packed in plastic bags at a rate of 2Kg / bag, the soil bags were placed in PVC pots. The design of the experiment was a randomized complete block, factorial. Factors of the experiment are 4 as follows: 1- Manuring: non- manured `Mo’and chicken manured Mil 2 treatments]. Summary and Conclusion -209- 2-Two cultivars of wheat (Triticum aestivum cv. Sakha 93 and Seds -1) 3-Salinity of irrigation water: water of dSm-1: 0.59 (W1) ; 8.29 (W2) ; and 11.02 (W3) [ 3 treatments . 4-Foliar spray with amino and humic acid:seven treatments as mentioned before. Treatments were done in 3 replicates, Soil fertilization: fertilizers were added to soil and mixed thoroughly as follows: Amonium nitrate (33.5%N) as a N source at the rate of 75 mg N/kg, super phosphate 6.8% P at the rate of 40 mg P/kg and the potassium sulphate (40% K) at the rate of 25 mg K /kg, respectively. Grains of wheat were soaked in a mixture of tap and saline water (8.29 dsm-I) for 24 hours, then were planted 10 grains per pot and irrigated with the tap water when needed up to 10 days (seedling emergence). The seedlings were then thinned into 5 per pot followed by application of the water treatments. One experiment was done with spraying at 15 days after sowing; another was done with spraying at 21 days after sowing . After 150 days the plants were harvested, washed, dried at 70°C and the dry matter and grain yields were recorded. Plant samples were taken ground, wet digested and N, P, K, Ca, Mg, Na and micro nutrients (Fe, Mn and Zn). The obtained results can be summarized as the following: Summary and Conclusion -210- Yield and Yield Components: Grains and straw yields: Applied chicken manure to soil significantly increased grain and straw yields under all levels of salinity.

The 15 DAS values were greater than the 21 DAS values. It could conclude, that the addition of chicken manure and humic and amino acids to the saline soil or when use salinity water may elevated the negative effects of salinity. Thus, the plant growth and yield could be increased by the addition of chicken manure and humic and amino acids under the saline conditions. |
