The Rosalina F 1 tomato hybrid was used in this study to produce organic tomatoes. There were five treatments, chicken manure, plant compost, animal compost, chemical fertilizer and humic acid. The highest values of fruit weight were found with treatment of chicken manure, 83.6 and 78.3g, in seasons 2019 and 2020, respectively. While the plant compost treatment recorded the highest values of plant height, 120 and 118 cm, in seasons 2019 and 2020, respectively. The lowest values of unmarketable crop in 2019 was 83.30g/plant with plant compost treatment and 88.33g/plant in 2020 was with chicken manure treatment, while the highest values of unmarketable crop were found when treated with animal compost, 136 and 125g/plant, in seasons 2019 and 2020, respectively. With respect to N and Ca percentage, the highest concentrations were recorded with plant compost treatment, 0.52, 2.98% and 2.95 2.89% in 2019 and 2020, respectively. Regarding K%, the highest concentration was recorded with animal compost treatment, 4.2 and 4.66% in 2019 and 2020, respectively. The trait of firmness firmness recorded highly significant values were recorded with chicken manure treatment, 0.36 lb/inch 2 in both seasons. It was found that total plant yield and marketable crop weight per plant recorded the highest values with chicken manure, 1736 and 1646g/plant (unmarketable crop weight per plant 90g) in season 2019, and 1628 and 1540g/plant (unmarketable crop weight per plant 88.3g) in season 2020, respectively. In most cases, no significant differences were realized between chicken manure and plant compost treatments. The lowest significant values of all measured parameters were achieved when tomato plants received chemical fertilizer or humic acid treatments.

Jaguar Yellow) plant under unheated plastic greenhouse conditions. This study was carried out for two successive seasons of 2016/2017 and 2017/2018 at the farm of the Arid lands Agriculture graduated studies and Research Institute (ALARI), Shoubra Elkheima area, Qalyobia governorate, Egypt. The experiment were laid out in a completely randomized design (CRD) with 3 replications, and the end results have been subjected to analysis of variance (ANOVA). Freshly extracted gerbera seedling have been planted into pots filled with peatmoss + sand (1:1), peatmoss + sand + vermicompost (1:1:1), peatmoss + sand + compost (1:1:1) with or without 250ml of Azotobacter + Azospirllum mixture, as biostimulant, and slow-release NPK (4.2g) or fast-release NPK (2.5g) fertilizers to each plant, to determine the effect of fertilizer, biostimulant and growing medium types on the production of potted gerbera. Growth and flowering characteristics were measured. Results indicated that medium combination of sand + vermicompost + peatmoss (1:1:1) with biostimulant, regardless of the fertilizer type, gave significantly increased results in all measurements, compared to all other combinations. Plants grown in medium supplemented with biostimulant and fast-release fertilizer, gave flowers with good qualities While the medium combination sand + vermicompost + peatmoss (1:1:1) with biostimulant in combination with either one of NPK mineral fertilizers (fast-release fertilizer and slow release fertilizer) gave significantly increased results in most parameters, shown in higher total vegetarian and quality when combined with slow release fertilizer than fast-release fertilizer. Under this treatment, number of leaves per plant was (24.8), number of daughter plants/pot (5.3/plant), Leaf greenness (SPAD) (59.00), number of flower (1.28), flower head diameter (8.3 cm) and flower stalk diameter was (2.72 mm). These records were all significantly higher than other treatments.

Global and regional interest in the sustainable management of limited freshwater supplies to meet the rapidly increasing population and food demands has resulted in advanced scientific research on ET measurement, rapid water accounting, and irrigation schedules in the NENA region. The primary goal of this paper is to compare actual daily evapotranspiration (ET) collected by a remote sensing model and validated by Energy Balance (EB) flux tower field measurements. The flux tower was installed in a wheat field in Sids Agricultural Research Station in Beni Suef Governorate. Through the integration of Moderate Resolution Imaging Spectroradiometer (MODIS) Terra and Sentinel-2 data, a new remote sensing-based ET model is built on two parties: Thermal condition factor (TCF) and vegetation condition fraction (VCF). The remote sensing-based ET estimation model was evaluated using ET field mea...

SUMMARY -Crop model programs are currently needed to study the impact of climate change on agricultural production. This could help the decision makers to implement future agricultural strategies together with different scenarios related to agricultural practices. One of these programs is DSSAT (Decision Support System for Agrotechnology Transfer), which is used to evaluate and predict wheat yield under all environmental conditions such as soil, weather, irrigation and fertilizers and simulate the yield of different wheat cultivars to select the cultivar(s) for different environments. We measured data taken from a field experiment carried out at Maryout (Northwest Coast of Egypt) during 1991-92, 1992-93 and 1993-94 growing seasons to evaluate the productivity of some bread wheat varieties under rainfed and supplementary irrigation conditions at different growth stages. The experiment included twenty-four treatments, which were the combination of four supplementary irrigation schedules: (i) only rainfed 170 mm of rainfall; (ii) one irrigation at heading stage 480 m 3 /ha; (iii) one irrigation at milk ripe stage 480 m 3 /ha; and (iv) two irrigations at the above stages (960 m 3 /ha) and six wheat varieties (i.e. Sakha 8, Sakha 69, Giza 155, Cham 4, Cham 6 and Gomam). Predicted and measured grain were compared and the results indicated that there were significant and favorable differences between the six wheat cultivars where Cham 4 and Giza 155 cultivars had the higher grain yield under rainfed treatment. Whereas, under one supplementary irrigation treatment Sakha 69 cultivar recorded the higher grain yield followed by the Cham 6 cultivar. Moreover, Cham 6 and Sakha 69 cultivars produced the higher grain yield under the two supplementary irrigation treatments. On the other hand, there was a significant increase in the grain yield with increasing supplementary irrigation times. The potential impact of climatic change on wheat production was evaluated by simulation of wheat production under climatic change conditions by the year 2040 compared to the predicted production under current conditions. In this respect results indicated that the grain yield increased differently according to the wheat cultivar. This may be due to the positive effect of duplication in CO 2 on wheat as C 3 plants. 'horizon 2040 en comparaison avec la production prévue sous les conditions actuelles. A cet égard les résultats ont indiqué que le rendement en grain augmentait différemment selon le cultivar de blé. Ceci pourrait être dû à l'effet positif de la duplication du CO 2 du blé chez les plantes C 3 telles que le blé.

The aim of this study is predicting degree day's unit and annual generations of the tomato leaf moth Tuta absoluta under current and expected future climate by using the relationship between the accumulated thermal heat units expressed as degree-days unit (DDU) and the population fluctuations. Evaluated how temperature influence the annual generation in four governorates in Egypt using the climate change data output from the HadCM3 model for A1 scenario proposed by the Intergovernmental Panel on Climate Change. The obtained results indicate that population of the Tuta absoluta in Qena governorate gave the highest number of generation as compared to other locations (EL Beheira, Giza and Fayoum governorates) under current climate. Generation numbers of T. absoluta under climate change conditions increased especially in Qena governorates. However, the expected generation numbers of the pest at 2050 and 2100 are be 12-14 and 13-15 generations per year, respectively.

As many evidences indicated that some remarkable changes could happen in climate scenario, the present work is mainly directed to discuss sensitivity of climate change upon the potato production in Egypt. The selection of potato product is mainly dependent upon that potato represent strategic crop cultivated in Egypt. The SUBSTOR potato model was employed to simulate physiological processes and yield of potato production. SUBSTOR model is a mechanistic, process-oriented model for tuber yield includes crop development. The present work introduces two possible cases of climate changes for the sake of climate crop production relationship. The actual measurements for potato production characteristics were used in the comparison with present and predicted. The climate change data is used from two general circulation models (CSIRO and HadCM3) for A1 greenhouse gases Scenario during 2050. The results of the work indicated that the potato yield decrease from 11 to 13% under climate change and the climate change data output from HadCM3 model gave the highest value of potato yield comparing with CSIRO model. And Valor cultivar gave the highest potato yield compared to Dezareah cultivar when the irrigation treatment taken place under current and future climate.
