Impact of Compost Tea Types Application on Germination, Nodulation, Morphological Characters and Yield of Two Lentil Cultivars
LABORATORY and field experiments were performed at Crop Science Laboratory and the Experimental Farm, respectively, Faculty of Agriculture, Menoufia University, Shebin El-Kom, Egypt, in order to evaluate the response of germination and seedling characters, nodulation, growth, nutrients uptake and yield of two lentil cultivars (Giza 4 and Family 29) to application of various compost tea types prepared from different agricultural residues (sugarcane bagasse, cotton stalk and rice straw) and their grades based on particles size (unfractionated, relatively coarse and fine). Application of compost tea includes twice ways applied together, i.e. seed priming before sowing and foliar application during growth periods (25 and 55 days after sowing). Results showed that Giza 4 significantly surpassed Family 29 for all parameters except germination %. Giza 4 outweighed Family 29 by 19.36 and 11.30% for seed yield/fad in first and second seasons, respectively. The compost tea types produced from the finest particles size (0.6-1mm) of the cotton stalk or rice straw compost revealed maximum values of germination and seedling characters, nodulation, growth, chlorophyll, NPK contents, yield and protein%. The interactions between lentil cultivars and compost tea were found to be significant for studied characters. It could be concluded that treated Giza 4 with compost tea produced from finest particles size (0.6-1mm) of cotton stalk or rice straw compost was found to be the best combination treatment for enhancing germination, nodulation, growth and productivity of lentil, indicating the importance of compost tea application to maximize lentil productivity.

Influence of Delivery Delay on Quality of Some Promising Sugar Cane Varieties under Aswan Condition
THE PRESENT work was conducted at Kom Ombo Agricultural Research Station, (latitude of 24o 28′ N and longitude of 32o 57′ E), Aswan Governorate, in the two seasons of 2015/2016 and 2016/2017 to study the effect of storage period before crushing for (0, 2, 4 and 6 days) on juice quality characteristics of three promising sugar cane varieties (G.84-47, G.2003-47 and C.57-14) in addition to the commercial variety G.T.54/9 (C9). The experimental design was randomized complete block design (RCBD) with three replications.Results indicated that brix and reducing sugars percentages tended to increase as storage periods increased up to six days before crushing. On the other hand, juice extraction, sucrose, purity, richness and sugar recovery percentages were decreased as the storage period was prolonged.Sugar cane varieties significantly differed in all studied traits. In both seasons G.T.54-9 variety recorded the highest values of juice extraction and richness percentages, while G.84-47 and G.2003-47 varieties gave the highest brix and purity percentages, respectively. Means while G.84-47 and G.T.54-9 varieties recorded the highest values of sucrose percentages in 1st and 2nd seasons, respectively. Interaction between the two factors markedly affected the rate of deterioration in all studied traits.These results might be helpful to decrease sucrose losses when delivery delayed of sugar cane, with assessment of optimum storage period. It is recommended that cane meantime should be delivered as early as possible to sugar mill to minimize sugar losses.

Improving Wheat Productivity by Application Types Different of Fertilizer under Newly Reclaimed Soil Conditions
TWO FIELD experiments were carried out at the Experimental Farm (Demo) of the Faculty of Agriculture, Fayoum University, during 2015/2016 and 2016/2017 seasons, to study the effect of organic and mineral nitrogen fertilizers under foliar application of micronutrients treatments on yield and its components of wheat plants. The experimental design was split-split plot arrangement in randomized complete blocks design with four replications where organic fertilizers were considered in the main plot, nitrogen levels arranged in the sub plot and the sub-sub plot was foliar application treatments. Results indicated that significant differences between organic fertilizers. Applying poultry manure at the rate of 10m3/fad. gave the highest values of all studied characters. Addition, mineral nitrogen fertilizer at 80kg N/fad led to significantly increased in the all studied characters as compared to using (60kg N/fad and 40kg N/fad). Significant differences were observed among the foliar spraying treatments. Spraying in the mixture micronutrients (Fe, Mn and Zn at 100g/200L water/fad) recorded the highest values for all studied characters. From the above results it could be recommended that fertilizing wheat plants by poultry manure at the rate of 10m3/fad and foliar spraying with mixture micronutrients (Fe, Mn and Zn at 100g/200L water/fad) as well as addition 80kg N/fad, to improve the productivity of wheat yield under newly reclaimed soil conditions in Fayoum Governorate.

Effect of Inter Row Spacing with or Without Weed Control in Wheat ( Triticum aestivum L.)
TWO FIELD experiments were carried out at the Experimental Farm of the Faculty of Agriculture (Demo), Fayoum University, during 2016/2017 and 2017/2018 seasons, to study the effect of row spacing and weed control treatments on yield and its components of wheat plants and its associated weeds. The experimental design was split- plot arrangement in randomized complete block design with three replications where row spacing was considered as the main plot, weeds control treatments arranged in the sub-plot. Results indicated that row spacing treatments were significantly on annual weeds (g/m2) and yield components in both seasons. Narrow row spacing at 15cm gave the highest values of plant height at harvest (cm), number of spikes/m2, grain and biological yield (ton/fad) in both seasons.The results indicated that the narrowest row spacing under this study (15cm) decreased the dry weight of total weeds by 42.22 and 43.29g/m2 in first and second seasons, respectively, compared to wide row spacing. Weed control treatments were significant on yield and yield components in both seasons. The herbicides treatment with Granstar+Topik gave the highest values for all traits under these study in both seasons. The interaction between row spacing and weed control treatments were reacted significantly on annual weeds (g/m2) in both seasons. Wheat sown under narrow row spacing 15cm and applying Granstar+Topik herbicides achieved the best crop of wheat under the experiment conditions.

Effect of Ascorbic and Humic Compounds Pre-Treatment on Growth Characteristics of Some Sugarcane Varieties under Salinity Stress
SUGARCANE ( Saccharum spp.) shows high sensitivity to salinity at various growth stages. A pot experiment was conducted at the Agricultural Research Center, Giza (latitude of 28.76 0N and longitude of 29.23 0E) under natural conditions in November 2015/2016 and 2016/2017. The present work was carried out to find out the influence of four soaking treatments (without soaking, tap water, ascorbic and/or humic acid) and three levels of salt stress (tap water, 3000 and 6000ppm NaCl) on some growth traits of three sugarcane varieties (viz. G.84-47, G.2003-47 and G.2003-49). The concentration of both ascorbic and humic acid was 1.0mM. After soaking in ascorbic and/or humic acids, five pieces of 2-budded sets were grown in plastic pots (45x50cm) containing soil of clay mixed with sand at 2:1.Emergence %, growth measurements (stalk height, stalk diameter, leaf area, stalk fresh weight, stalk dry weight, root fresh weight, root dry weight, total chlorophyll and proline content) were recorded. The results indicated that increasing salinity levels under all soaking treatments was accompanied with a gradual reduction in all studied traits of the evaluated sugarcane varieties, except proline content, which showed an opposite trend.Under conditions of this work, the commercial G.84/47 cane variety showed higher tolerance to raising salinity level up to 6000ppm in irrigation water over the other two ones. Meanwhile, soaking cane cuttings of the tested varieties in ascorbic and/or humic acids can be recommended to improve their growth traits when canes irrigated with saline water.

Effect of Reduced Irrigation and Potassium Fertilization on Quantity and Quality of Giza 95 Cotton Plants
TWO FIELD experiments were conducted at the Farm of Sids Agricultural Research Station, ARC, Egypt, during 2016 and 2017 seasons to study the response of cotton to potassium fertilization (12, 24, 36 and 48kg K2O) as soil application as well as 5kg K2O/fad as foliar spraying three times at squaring, beginning of flowering and top of flowering) under different irrigation intervals at recommended irrigation interval (every 12 days), every 15 days, every 18 days and every 21 days). The results show that increasing potassium fertilization up to 36kg or 48kg K2O/fad as soil application as well as decreasing irrigation interval to 12 days exhibited the highest values of plant height, number of fruiting branches/ plant, number of open polls/plant, seed cotton yield, earliness % and seed index as well as leaf content of N, K, chlorophyll A and B and carotenoids. On the other hand, lint percentage and fiber properties did not respond to either potassium or irrigation treatments, while P content increased as increasing water irrigation. Increasing both potassium levels and the irrigation intervals improved water use efficiency and water utilization efficiency. The results of the interaction between potassium and irrigation treatments reveal that irrigation cotton plants every 15 days when fertilized with 48kg K2O/fad as soil application produced highest growth, yield and its components and chemical content of cotton leaf equal to these irrigated every 12 days and supplied water 36 or 48kg K2O/fad.

Intercropping Systems of Sunflower and Peanut under Different Irrigation Regimes and Potassium Fertilizer Levels
TWO FIELD experiments were conducted at the research farm of Ismailia Governorate, Egypt during 2016 and 2017 summer seasons. This study was used to determine the suitable spatial arrangement of sunflower and peanut in an intercropping system under three irrigation water levels and three fertilizer (K) levels on yield, the land and water equivalent ratios and farmer's net income.The three irrigation treatments (0.7, 1.0 and 1.2ETo), the three K fertilizer levels (57, 86 and 114K2O kg/ha) and the four intercropping systems of sunflower and peanut (different spatial arrangements) were arranged in a strip split plot with three replications.The results indicated that application of 1.0 and 1.2ETo had similar effect on most of yield traits of the intercrops. Application of 114K2O kg/ha had the highest values of most yield traits of the intercrops. Intercropping sunflower with peanut (S1), where peanut seeds were sown on both sides of all the raised beds, sunflower seeds were sown on one row above the raised beds and the following bed was left without intercropping gave the highest values of peanut and sunflower yield and its attributes.In conclusion, the highest yield, land and water equivalent ratios, as well as farmer's net income can be obtained under 1.2ETo, 114K2O kg/ha and S1 intercropping system.

Required Interval of Weather Data for Proper Irrigation Scheduling
CLIMATE variability is very common in Egypt recently, therefore studying its effects on irrigation scheduling for crops is important. The objective of this study was to define a number of years of former weather data prerequisite to estimate evapotranspiration (ETo) to schedule irrigation in three sites in Egypt (El-Gharbia, Beni Swief and Sohag). Daily values of weather data were collected for 10 years (2008-2017).Monthly ETo values were calculated by The BISm model. Descriptive statistics (mean, range, R2, CV and SD) were done to determine the temporal and spatial variability between monthly values of weather elements, as well as ETo. Furthermore, assessment of ETo values trend (decreasing or increasing) was done.The results showed that there were increasing temporal and spatial trends in the 10-year weather data, as well as ETo values in the 3 sites. However, it was more pronounced from 2015 to 2017. Furthermore, the results indicated that the range, CV% and SD were lower in the 3-year interval (2015-2017), compared to 10-year interval for all sites. There were stronger relationships between weather elements and ETo values in the 3-year interval, compared to 10-year interval, as represented by R2 values.Thus, it can be concluded that the recent 3-year interval is the most suitable interval for ETo calculation for proper irrigation scheduling to improve water management on field level in Egypt.

Effect of Nano-Fertilizer and N-Fertilization Levels on Productivity of Egyptian Cotton under Different Sowing Dates
Two field experiments were carried out on clay soil in El-Gemmeiza Agric. Res. St., ARC, El-Gharbiya Governorate, during 2016 and 2017 to study the effect of nanofertilizer and N-fertilization levels on productivity of cotton Giza 86 under two sowing dates. The experiment design was a split split-plot. The main plots involved two sowing dates; (Early at 8th April and Late at 8th May). While, the sub plots were allocated to three treatment of nanofertilizer (without, Lithovit 2.5g/L and Lithovit 5g/L). Application three times (at squaring,initiation of flowering and two weeks after flowering). While, the sub sub-plots were allocated to three N-fertilization levels, (50%, 75% and 100% recommended dose). The most importantresults obtained could be summarized as follows: Sowing date had a significant effect on growth, yield and its omponents. Where, the early sowing date surpassed the late sowing date. The levels of N had significant effect on growth, seed cotton yield and its components in both seasons. The rate of N (75%) gave the good averages in this respect. The Nano-fertilizer by Lithovit had significant effect on growth, seed cotton yield and it compounds. All treatments had a not significant effect on fiber properties. Early sowing date in combination with the N fertilizer (45kg N/fad) and foliar application with Lithovit (5g/L water) for obtaining gave the high productivity of Egyptian cotton variety Giza 86.
