F.FoudaDepartment of Soil sciences, Faculty of Agriculture, Mansoura University- El-Mansoura-Egypt.Journal Article20210226The current experiment was established in the experimental farm of faculty of agricultural, El-Mansoura University, Egypt, to check the growth, yield and quality of carrot (<em>Daucus carota</em> L. ) cv. Korea against the interaction application of mineral fertilization at different rates from recommended dose (50, 75 and 100%), foliar application of humic acid and addition of effective microorganisms (EM) all under compost town refuse as organic fertilization during season of 2017-2018. Experiment was laid out in complete randomized design with 14 treatments and each treatment was repeated three times.In general, it can be concluded that fertilizing with compost town refuse + 75% NPK +foliar application of humic acid and effective microorganisms gave the highest mean values of root length, diameter, weight and total yield as well as N, P, K%, Fe, Zn, Cu, Cd (mg kg<sup>-1 </sup>) as chemical components and total soluble soilds, total carotene, total carbohydrates, total sugar and vitamin A as quality parameters comparing with the control (without fertilization). As for soil availability, it was observed the highest mean values only with town refuse over control.Mansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368512120210101An Integrated Unit for Hatching and Rearing Quail91615200310.21608/jssae.2021.152003ENT. H. EL-ShabrawyAgric. Eng. Dept., Agric. Fac. Mansoura Univ.M. A.Al-RajhiAgric. Eng. Research institute, Agric. Research Center, EgyptJournal Article20210226This study was conducted to compare between the new integrated quail rearing unit with egg hatching sub-unit, and common egg incubator with traditional rearing system for (black Japanese quail and white jumbo quail) at two eggs hatching positions (vertical position with small end up and down). An integrated unit provided with upper egg incubator and furnished rearing battery cage located lower of it. The chicks were reared for 40 days of age in traditional litter floor and in furnished battery cage. The evaluation include the percentage of hatchability, chick weight, growth performance and mortality number of quail. The result indicated that the new incubation unit was able to maintain a high hatching percentage of 78.53 % for eggs of white jumbo quail with vertical egg position with small end down in average of hatching period 17 days. Chicks were growing in normal weight at 6.99 and 8.19 gram and did not suffer from any disability for black Japanese and white jumbo quail eggs, respectively and with vertical position with small end up. At different time intervals the growth performance of quail didn't show significant difference among the treatment viz. common commercial egg incubator and new incubation sub-unit. The mortality number at the first days increases for quails hatched in common commercial egg incubator. The same capacity attached egg incubator saved about 81.25 % of the total cost compared to the common commercial egg incubator, so it is recommended to use the integrated unit for incubating and rearing quailMansoura University, Faculty of AgricultureJournal of Soil Sciences and Agricultural Engineering2090-368512120210101Assessment of Land Suitability Index for the Wheat Crop Production by Using Sys’s Method and ALES Program172415200410.21608/jssae.2021.152004ENHeba S. A.RashedSoil and Water Department, Faculty of Agriculture, Moshtohor, Benha University, Egypt.Journal Article20210226Land suitability index for the wheat cultivation is carried out in east of the Nile delta of Egypt. The present area occupies the southern part of Ismailia canal and is bounded by latitudes 30° 35' 10"–31° 05' 00" N and longitudes 31° 15' 0"–32° 22' 08" E. Seventeen soil profiles were dug and classified as Typic Torrifluvents, Vertic Torrifluvents, Lithic Torriorthents, Typic Torripssaments and Typic Haplosalids. The criteria of land suitability for wheat production were adopted from guidelines of FAO (1976) and were carried out using two methods (Sys’s method and ALES program). Most of the soils under study were suitable for wheat crop production by using both two approaches. The Sys’s method has three classes, highly suitable (S1): 30.75%, moderately suitable (S2): 60.55% and marginally suitable (S3): 8.15%. While the results obtained by using the ALES program also has three classes, highly suitable (S1): 25.50%, suitable (S2): 65.80% and permanently not suitable (NS): 8.15%. Marginally or not suitable areas occurred in lakebeds mapping unit and agree with the adverse soil physical and chemical qualities (very poor drainage, heavy soil texture, high EC, high ESP and high pH). The compare of the results of the two methods indicated that, high level of agreement between the Sys’s method and the ALES program, whereas all mapping units have the same classes except for two mapping units. At the local level, this study may be utilized by farmers and decision-makers for maintaining food security and for achieving sustainable agricultural development.
