Timeliness is very important in large agricultural projects, which are characterized by large areas requiring different numbers and sizes of agricultural equipment. In order to choose the best equipment, and give the right management decisions. The intelligent manager must be aware of the optimum planting time, because the varying in the time of planting on sawing date leads to loss of productivity called (Timeliness) may reach about half of the crop.Determining the optimum time for planting is important to reduce the costs of declining yield due to timeliness and to obtain the highest yield from the farm.This research aims to cover these point machine sizes and operational available time affected the crop net return. Timeliness coefficients’ equation was adjusted for famous Egyptian crops, for maximum crop yield to avoid the early or late establishment crop yield losses.

Recently ecological intensification is introduced as a modern approach for enhancing the productivity of organic farming systems to maximize their economic returns. For this purpose, a pot experiment was conducted during the autumn season of 2018 at the Experimental and Agricultural Research Center, Mansoura University in order to evaluate the efficiency and applicability potential of engineered organic blocks derived from mineral and organic additive combination for improving cucumber productivity under sandy soil conditions. In a split-split plot design with three replicates, 36 treatments were arranged to represent three combinations of compost application (i.e. 100% compost, 75% compost + 25% rice straw and 50% compost + 50% rice straw), organic additives (control, seaweed (SW), chicken manure (CM), and seaweed + chicken manure combination) and three mineral additives (control, natural mineral ores (rock phosphate and feldspar) and a partial dose of NPK fertilizers. The obtained results cleared that 100% compost, (SW) + (CM) combination and the partial mineral NPK application were the superior treatments for increasing marketable yield productivity (Mg Fed-1), quality of fruits shape (weight, length and diameter) as well as nitrogen (N), phosphorus (P) and potassium (K) concentrations in fruits. The mutual interaction among mineral and organic constitutions of the engineered blocks introduced mineral ores application as an efficient treatment with a high capability to improve the uptake of plant nutrients (N and P in particular). It is recommended, therefore, using the combination of organic additives (e.g. CM, SW) as well as mineral additives (e.g. rock phosphate, feldspar or partial dose of NPK) to achieve the ecological intensification in organic farming systems.

The good pressing of the soil around seeds at planting moment is mean that perfect of seeding depth consequently increasing seeds germination rate. So, the technology of planter press wheel helpful to keep up the requirements of pressing the soil above the seeds, covering and seeds depth. The objectives of this study is to determine the statics and dynamics forces requirements to realize a suitable compress on planted furrow for different types of seeds crops. The constructed press-wheel unit tested under different variables of two press-wheel ratio (W1=7.3 and W2=3.3), four spring index "C" (10.5, 9.3, 7.7 and 7.1) and four adding load "AL" (99, 126, 167 and 204 N for the first press wheel “W1 = 7.3” and 120, 157, 198 and 234 N for second press wheel “W2 = 3.3”). All variables were conducted for sandy soil under two soil moisture contents of 4.8 and 13.9% “wb”. The response each of; applied loads, spring index, press wheel factor on proposed press wheel structure, it easy to define the reaction of applied loads as changing in displacements or differences between Kinetic and Potential Energy. The arbitration criteria for judging on the final relationship between action (as adding load) and soil reaction (as soil rut) can be summarized as change in soil deflection relative to travel system. From the results it can concluded that the highest soil rut recorded at wheel ratio of 3.3, the two soil moisture contents, press on soil and at decreasing the forward speed and spring index. The high total energy found at the highest forward speed, applied load and lowest the both of spring index and wheel ratio.

In a field experiment, plant growth, nodulation status, yield, mineral content, and the rhizosphere enzyme activities of peanut (Arachis hypogaea L), cultivated in sandy loam soil were studied under the effect of the amendment with humic acid and the inoculation with plant growth promoting rhizobacteria (PGPR) that applied as foliar and\or as seed coating. Bradyrhizobium was used as a single inoculum and\or accompanied with PGPR (Azospirillum sp.+ Paeniacillus polymyxa+ Serratia marcescens) with or without humic acid. Results revealed that inoculation with Bradyrhizobium as a single inoculum or accompanied with PGPR, increased significantly shoot dry weight, and yield of peanut under coating and foliar applications. Incorporation of humic acid at two rates of 3L/fed and 5L/fed as foliar and seed coating gave the highest significant values for all tested parameters. inoculation with Bradyrhizobium as single inoculum or accompanied with PGPR enhanced the nodulation status and nitrogenase activity. Also, the values of nodules and nitrogenase activity achieved by coating application method were higher than those recorded by foliar application. In addition, the combined application of coinoculation Bradyrhizobium and PGPR accompanied with humic acid led to significant increases in the content of N, P, and K in shoot plant and in soil. Likewise, humic acid amendment can stimulate the microbial activities in the rhizosphere soil. Higher values of dehydrogenase activity in the rhizosphere soil and carbon dioxide were found with coinoculation and foliar application of humic acid.

Two field experiments were conducted at two sites in Sakha Agric. Res. Station Farm, North Delta, during two successive winter seasons, 2017/2018 and 2018/2019 to study the effect of individual and combined applications of gypsum, compost tea and biochar on some soil properties and wheat (Triticum aestivum, L) productivity under saline and saline-sodic soils. Gypsum requirements (G), 400 L compost tea (C), 1 Mg biochar (B1) or 2 Mg biochar (B2) were applied. Data revealed that application of G+ C+ B2 decreased soil ECe by 28.06 and 13.16 %, SAR by 17.23 and 8.92 %, ESP by 17.23 and 8.92 % for site 1 and site 2, respectively as compared to the control. While, the sodium removal efficiency (RSE %) with different treatments was increased in somewhat according to the following order: G+C+B2 ˃ G+C+B1 ˃ G+C ˃ G+B2 > G+B1 ˃ G ˃ C+B2> B2 > C+B1 > C > B1 compared to that of the initial soil. Also, the application of different soil amendments decreased soil bulkdensity and increased soil porosity after the two growing seasons. The plant height, 1000-grain weight, grain yield and straw yields of wheat were significantly increased with different treatments.

The objective of this work is to study the improvement of soil physical properties under different soil treatments using saline water. The field experiment was conducted at Ras Sudr station South Sinai. in sandy loam soil in order to study the effect of the application of farmyard manure (FYM), agricultural elemental sulfur (A.S.) and their combinations (FYM + A.S.) on some soil physical and chemical properties. The experiment used three rates of farmyard manure (10, 15 and 20 ton/fed), three rates of agricultural sulfur (50, 75 and 100 kg/fed) and their mixtures by 20 ton/fed farmyard manure with each of 50, 75 and 100 kg/fed of agricultural sulfur. In addition, three levels of irrigation water applied (50, 75 and 100% from available water). The barley crop (Giza 123) as indicator which was planted in November, 2017 using drip irrigation system. Irrigation water used for the experiment has values of, Ec and SAR (sodium adsorbed ratio) 8.96 dS.m-1 and 22.74, respectively. The results showed that the effect of all studied soil treatments were significantly decreased the soil bulk density, while the effects of irrigation water applied rates were significantly increased relatively to control. Hydraulic conductivity values were significantly decreased by using different rates of FYM and combination FYM+A.S., while it significantly increased using A.S treatment alone relatively to control. The increase of soil available water was in the order FYM+A.S. > FYM > A.S. > control. Their values were affected significantly by different treatments and integrated application rates of FYM + A.S. Hydraulic conductivity values were significantly decreased with increasing irrigation water levels. Data clearly evident that the size of water stable aggregates as well as mean weight diameter were improved due to the use of FYM and combination FYM + A.S. as compared to application of A.S. alone. The EC values decreased with increasing rates of FYM and combination (FYM+A.S.), while reverse trend was noticed with A.S. alone. Application of soil treatments decreased each of SAR, ESP and pH, while these parameters were increased with increasing levels of irrigation water applied. The effect of the treatments on Investment Ratio (I.R.) could be arranged as follow: 20 ton/fed FYM + 100 Kg/fed A.S. >15 ton/fed FYM >20 ton /fed FYM + 75 Kg/fed A.S. > 20 ton/fed FYM > 20 ton/fed FYM + 50 Kg/fed A.S. > 10 ton/fed FYM >75 Kg/fed A.S. >100 Kg/fed A.S. > 50 Kg/fed A.S.> control under 100% irrigation water applied.
