In addition, hand hoeing (twice) and weed check (control), under influence of different application methods as pre-emergence (experiment 1) or pre-planting (experiment 2) on vegetative growth and grain sorghum were simultaneously examined. Each experiment was laid out in a Randomized Complete Blocks Design, with four replicates. The results showed that there was no difference on efficacy of weed control between two application methods of soil-herbicides whereas there was satisfactory controlling effect of total weeds in both seasons. Also, the results revealed that in the preemergence application gave the highest injury in vegetative growth, which were inversely related between the vegetative growth and yield and its components. Whereas the increasing reduction in number of plants/plot, yield and its components decreased. On the contrary, in pre-planting application there was no adverse effect on vegetative growth, rather there was a positive correlation, whereas increases in number of plants/plot, yield and its components increased, in both seasons. Generally, it is concluded that, sorghum vegetative growth, yield and its components were not affected by these herbicides, so that appear to have good potential for controlling effect on weeds and selectivity of grain sorghum when applied pre-planting (14 days from application) but (pre-emergence) is risky.","PeriodicalId":11430,"journal":{"name":"Egyptian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76735228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each field trail included the following treatments: a) Mulching with black and green polyethylene sheets, b) Mulching with rice or wheat, straw c) Herbicides (Atazan 75% WG at 50 g fed. and Steler star 21% SL at 300 cm fed.) both at full rate (alone) and at reduced rate with their integration by different mulching or with adding mineral oil, beside, Maister power 4.53% OD, at full rate alone (500 cm fed.), with hand hoeing twice at 20 and 40 days after sowing and weedy check. Each experiment was laid out in a Randomized Complete Blocks Design with four replicates. The results showed that both Atazan 75%WG and Steler star 21%SL at reduced rate 50% of full rate (25 g and 150 cm fed., respectively) combined with mulching rice or wheat straw (both of them at 10 ton fed.), also, the same herbicides at reduced rate 25% of full rate (37.5 g fed. and 225 cm fed., respectively) with adding mineral oil at 1% gave superiority a significant differences whereas, weed control efficiency of Atazan combinations reached to (87.8, 86.8 and 84.3%), while Steler star combinations were (88.6, 87.6 and 84.9%), compared to full rate of each Atazan and Steler star alone (69.0 and 73.8%, respectively) in the first season. In the second season the same trend was achieved as the previous treatments.

The same trend occurred in the econd survey at 85 DAP.

The seventeen quinoa genotypes were arranged in a randomized complete blocks design (RCBD) with three replicates. The results clearly indicated that the earliest mature and shortest duration genotypes were Giza-1, QS17-1 and QS18, which stayed only 119 days in the field, whereas QS14 and QS16 accessions, stayed up to 147 days from planting date till harvest as a moderate maturity accessions in their growth duration. The rest of the genotypes stayed between 120 and 140 days from planting to harvest as a short to moderate duration. The highest values of plant height and the number of branches per plant were recorded for QS16 accession, whereas the lowest values were recorded for QS17-1 accession in both seasons. The heaviest 1000-grains weights were recorded for QS18, QS17-1 accessions and Giza-2 cultivar. Meanwhile the lightest 1000-grain weight were recorded for QS16 and QS14 accessions, in both seasons, regarding grain yield per plant and per ha, Misr-1 cultivar recorded the highest values, while QS17-1 recorded the lowest values in both seasons. The study concluded that Misr-1 cultivar gave a high yield potential under sandy soil conditions, while Q27, Q21, Q26, Q18 and Q22 are promising accessions for developing new varieties. Molecular diversity was measured using inter simple sequence repeat (ISSR) and random amplified polymorphism DNA (RAPD). The results revealed that the polymorphism level differs from one ISSR primer to another, which reflects the primers ability to detect diversity among quinoa genotypes. On the other hand,the data revealed the ability of RAPD to discriminate among the seventeen quinoa genotypes. Combined data across ISSR and RAPD systems explored similarity indices among the seventeen quinoa genotypes. The highest value was 94% among genotypes Q27, Q29, Q12 and Q29 and genotypes Q18 and QS16. While, the lowest values were recorded among genotypes Q26 and QS17-1 followed by genotypes Giza-2 and Misr-1 and also genotypes Giza-2 and Q29.

The present investigation was carried out at Al-Fayoum Governorate, (29°17ˋ N; 30°53ˋ E), Egypt, during 2017/2018 and 2018/2019 growing seasons. The objective was to study the effect of saline soil in three locations (villages), namely S 1 , (3.57 dSm -1 ) Monshat Sinnuris, S 2 , (8.6 dSm -1 ) Monshat bani Othman, and S 3 , (11.84 dSm -1 ) Monshat Tantawy, on plant growth, quality and yield traits of ten multigerm sugar beet varieties. The experimental design was a randomized complete blocks with three replications. The results showed that root yield and sugar yield, as well as root dimensions significantly decreased by increasing soil salinity levels as compared with the control treatment. Under severe soil salinity, Florima cultivar was superior in root and sugar yields (13.71 and 1.82 ton/fed.). respectively. On the other hand, Euklid cultivar recorded the least values (11.38 and 1.39 ton/fed), respectively. As for the interaction between soil salinity levels and sugar beet varieties, the highest values for root and sugar yields were recorded by the varieties Florima, Toro, Cleopatra , Tarbelli , which were cultivated under severe soil salinity (11.84 dSm -1 ). The results recommended the above four varieties to be cultivated by farmers under saline soil. These varieties are tolerant to soil salinity and they can produce a stable root and sugar yields in the stressed soil. Heritability of metric traits is of great significance to the breeders as its magnitude indicated the accuracy with which a variety can be recognized by its phenotypic expression and determines the generation in which selection can be profitable. The results showed that five varieties had a salinity susceptibility index (SSI) based on root and sugar yields <1 and were relatively tolerant to salinity stress.","PeriodicalId":11430,"journal":{"name":"Egyptian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79089641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
