To assess the genetic parameters and phenotypic correlation coefficients for the studied traits of promising restorer lines had earliness and high yielding during F<sub>3</sub> and F<sub>4</sub> generations in hybrid rice program. Twenty populations used for each two crosses IR69625A x Giza 178R and G46A x Giza 178R evaluated in F<sub>3</sub> and F<sub>4</sub> generations. Seventy five plants divided to five groups for each population. F<sub>3</sub> and F<sub>4</sub> generations showed highlysignificant and positive variation among populations for the studied traits during two seasons. The means values for the studied traits in F<sub>4</sub> population were higher than of F<sub>3</sub> populations except days to heading, indicating the effectiveness of selection for these traits. The two crosses combinations recorded high heritability coupled with high genetic advance as percent of mean indicating to the presence of non- additive gene action in both populations. There were positive and significant associations between grain yield and the studied traits of all populations in both generations, indicated that, selections for seed set % and grain yield were effective in later generations. It could be concluded the presence of genetic diversity for two generations for the studied traits, high heritability in broad sense which indicated that genotypic variance effect play an important role in inheritance of these traits for developing new plant types using as a restorer lines in hybrid rice program.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-366912320210301Effect of Irrigation Intervals and Foliar Applications with Some Nano-Fertilizers on Growth and Productivity of Globe Artichoke Plant: A-Vegetative Growth and Chemical Content in Leaves20921615434110.21608/jpp.2021.154341ENE.

Also, agriculture sector actively consumes large amounts of fresh water share in Egypt. Agricultural drainage water represents a significant percentage of water if it is reused again by raising its quality. So, this could be obtained by using magnetic technology (water/filed) as a means of mitigation lack of water by reusing agriculture drainage water in vegetable crops irrigation like tomato and studied plant productivity under these conditions. The objectives of this research were to evaluate the efficiency of magnetized drainage water and some anti-stressors on tomato plants behavior under Delta region conditions. The data presented in this paper are the results of two field experiments and it was observed that irrigation magnetic agriculture drainage water superior untreated plants in their effects on most of studied parameters. Concerning anti-stressors treatments, melatonin followed by glycine betaine recorded the best effects on plant growth, chemical composition, enzymes activity as well as yield and fruit quality parameters in both seasons. However, plants irrigated with drainage water only achieved the lowest values of all parameters as a result of salinity stress except fruit quality. The most concluded treatment of the superior positive effect on tomato plant productivity was irrigation with magnetized drainage water with foliar spray with melatonin, also it may be considered as the best option to save water under its scarcity and limited sources.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-366912320210301Effect of Plants Distribution Systems on Growth, Yield and Quality of Cotton Variety Giza 96 under Different Levels of NPK Fertilization24324815670310.21608/jpp.2021.156703ENEl-D.

Commonly, the first cycle of selection (C<sub>1</sub>) for frequent-cutting tolerance gave a cumulative realized gain over cuttings in green forage yield over the base population reached 9.09, 76.38 and 46.62% when evaluated under infrequent, frequent and very frequent cutting regimes, respectively. Meanwhile, the second cycle of selection (C<sub>2</sub>) for frequent cutting tolerance gave a substantial realized gain in green forage yield relative to cycle one reached 108.6, 94.52 and 180.56% when evaluated under infrequent, frequent and very frequent cutting. Cumulative realized gain over cuttings in green forage yield related to the average of the evaluated check varieties were -23.14, 104.2 and 177.6 when evaluated under infrequent, frequent and very frequent cutting regimes. Meanwhile, the second cycle of selection (C<sub>2</sub>) gave a cumulative realized gain over cuttings in green forage yield relative to the average of the first cycle (C<sub>1</sub>) reached 67.32, 218.6 and 367.1% when evaluated under infrequent, frequent and very frequent cutting regimes. It was evident that the realized gain in green forage yield from selection for frequent cutting tolerance among barseem ecotypes was more obvious after the second cycle of selection proposing that successive cycles of selection might result in better gains. Also, the superiority of selected cycles (C<sub>1</sub> and C<sub>2</sub>) was clearly shown over the studied check varieties. Meanwhile, the advantage of selection for frequent cutting tolerance was sounder and more illustrative, when improved cycles were evaluated under very frequent cutting regime.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-366912320210301Developing Drip Irrigation and its Nitrogen Fertigation, Using Sub Recommended Levels for Commercial Production of Clay Loam Soil Cultivated Banana Plants31332116120410.21608/jpp.2021.161204ENT.

Egypt.Journal Article20210305During 2017/2018 and 2018/2019 seasons, two experiments under field conditions have been performed at Sakha Agricultural Research Station (ARC) Experimental Farm in Egypt, to find out the effect of drainage treatments (water table depths) on growth, yield and its components of four wheat cultivars. Every experiment had been in three replications and had been performed in a split-plot design. The main-plots were dedicated to drainage treatments (conventional drainage at 120 cm and two controlled drainage at 80 and 40 cm water table depth). The sub-plots were allocated to wheat cultivars (Sakha 95, Gemmeiza 11, Misr 2 and Giza 168). Data on the amount of water applied to the subsurface drainage system revealed that, the 40 cm treatment saved about 501.9 and 602.28 m<sup>3</sup>/fed, or about 23.75 and 28.50% of applied irrigation water in 1<sup>st</sup> and 2<sup>nd</sup> as compared to the 120 cm depth treatment. The results revealed that drainage treatment 40 cm below soil surface significantly increased early characteristics, growth and yield and wheat characteristics, giving the highest values of followed in the two seasons, by both controlled drainage and conventional drainage. Sakha 95 cultivar exceeded the other studied wheat cultivars (Gemmeiza 11, Misr 2 and Giza 168) and obtained the highest values for days to heading and maturity and for growth, yield and its components in both seasons. The drainage can be concluded depth 40 cm below soil surface for Sakha 95 and/or Gemmeiza 11 cultivars produced the highest growth and productivity under the conditions of the Sakha district in Egypt's Kafr El-Sheikh Governorate.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-366912320210301Improving Growth, Productivity and Oil Yield of Nigella sativa, L.
