Two field experiments were carried out during 2014 / 2015and 2015 / 2016 seasons in the Kabret El-Bahara area , Suez Governorate to study, the response of wheat Sids 13 cultivar to the combination between five levels of mineral fertilization (without, N.P.K. fertilization, 40 of the recommended, 60, 80 and 100% rate) and spring with five levels bio-fertilizers treatments (without (tap water), bacteria (Azospirillum) 150 ml., bacteria (Rezobium) 150 ml., bacteria (Azotobacter) 150 ml. and Bio-Green Merakl compound 250 ml./200 liters/ fed. Using the split plot design which, the bio-fertilizers treatment were distributed in the main plots, whereas mineral fertilization in subplots in four replicates.The obtained results can be summarized as follows:The results showed that a significant increase in yield and yield components using ground mineral fertilization at the rate of N.P.K. fertilization ware 100% in the 1 st .seson and 80%of the recommended, dose in both seasons, respectively, without any significant between 80 and 100%, respectively. Also, the findings revealed that the five bio-fertilizers of marked differences were significant and increased the yield and yield components and the best bio-fertilizer was a Bio-Green Merakl compound 250 ml., in both seasons.The interaction between mineral and bio-fertilizers gave sign increases in yield and its component. The best practice at a rate of N.P.K. fertilization is 80% of the recommended + spraying with Bio-Green Merakl compound of 250 ml. /fed., in both seasons.The results showed also that mineral fertilization at the rate of 80% of the recommended and spraying with Bio-Green Merakl compound 250 ml of resulted in significant increase, in the chemical components of wheat grains namely: nitrogen, total protein, phosphorus and potassium in both seasons.It was found from the calculation of the economic yield of crop that the use of the high rate of mineral fertilization at the rate 80% of the recommended and spraying with Bio-Green Merakl 250 ml /fed is the best experimental economic transaction for the farmer under South West of Suez Canal conditions.
Two field experiments were carried out during 2015 / 2016 and 2016 / 2017 winter seasons in the Kabret El-Bahara area -Suez Governorate, Egypt to study the response of fodder beet (Beta vulgari, L.) Rotta cultivar to the combination between four levels organic manure fertilizer treatments at a rates of 10, 20, 30 and 40 m 3 / fed and application with four levels of potassium fertilizer treatments (24, 36, 48 and 60 kg k 2 O / fed. Using the split-plot design which, the organic manure treatment were distributed in the main plots, whereas, the potassium fertilizer treatments in sub-plots in four replicates.The obtained results could be summarized as follows:The results showed that the higher levels of organic fertilizer gave the highest values and the best was the level of 40 m 3 / fed Compared to the level of 10 m 3 / fed In all the characteristics of the study at 100 and 150 days from sowing and also the characteristics of the yield and its components at harvest in both seasons.The increase of potassium fertilization added to soil at a rate of 60 kg k 2 O / fed resulted in the highest values of growth traits at (100 and 150 days from planting), yield and its components at harvests compared to the levels of potassium fertilization at the levels of 24, 48, 60 kg k 2 O / fed, respectively in both seasons.The results also showed that the addition of organic fertilization at a rate of 40 m 3 / fed along with potassium fertilization at a rate of 60 kg K 2 O / fed gave the highest values in the studded characteristics of growth, yield and its components in both roots and tops. It was also found that the increase in the protein content of the top and roots as well as total carbohydrates was detected due to the treatment 40 m 3 / fed organic fertilizer plus 60 kg K 2 O / fed added to the ground, respectively, in both seasons.Likewise the results revealed that the content of the top of nitrogen and potassium was highest in the roots and reached to the using the 40 m 3 / fed organic fertilizer along with 40 m 3 / fed potassium fertilization of 60 kg K 2 O/ fed.The results of the calculation of the economic yield of the crop showed that the cultivation of beet crop by using organic fertilization at a rate of 40 m 3 / fed plus potassium fertilization at a rate of 60 kg / K 2 O/ fed proved to be is the best experimental economic experiment for the farmers.
The field experiment was carried out during two successive summer seasons of 2014 and 2015 at the agricultural experimental station of Khamisa, Desert Research Center Siwa Oasis, to study the response of three sunflower varieties, i.e. Hysun333, Sakha 53 and Giza 102 to foliar application by natural compounds chitoker. Seven natural compound treatments which used were , 1-without natural compound (as control), 2-spraying by 150 ml./100 liters in the vegetative growth stage, 3spraying by 150 ml./100 liters in the vegetative and syphilis growth stages. 4-Spraying by 200 ml./100 liters in the vegetative growth stage, 5-spraying by 200 ml./100 liters in the vegetative. 6-Spraying by 250 ml./100 liters twice in the vegetative growth stage, and, 7-spraying by 250 ml./100 liters twice in the vegetative and syphilis growth stages.The obtained results could be summarized as follows:Sunflower verities were differed significantly in yield and its components, oil contents and oil yield. Giza 102 variety was superior to Hay Sun 333 and Sakha 53 varieties.A significant difference between the parameters of the natural compounds as chitoker, where the spraying twice by chitoker at 250 ml./100 liters of during the vegetable and flowering stages had a significant increase as compared to the rest of the treatments. All studied traits were significantly affected by the interaction between varieties and spraying by different chitoker treatments. An general, sprayed Giza 102 variety twice by the natural Chitoker at 250 ml. / 100 L. rate during vegetative and pre-flowering stages produced the highest yield, yield components and oil yield.The results of the calculation of the economic yield of the crop showed that the cultivation of the sunflower crop in Giza 102 + spraying with the natural compound Chitoker rate of 250 ml./100 liters of water in two stages are spraying in the stage of vegetable growth and spray in pre-growth flowering Is the best experimental economic transaction for the farmer, With some other factors being given an economic rate but to a lesser degree. This study concluded that the cultivation of Giza 102 sunflower variety + spraying twice with the natural compound Chitoker rate of 250 ml./100 liters of water in two stages of vegetable and pre-growth of the Zahra under the conditions of Siwa Oasis gave the best results economically.
