A FIELD experiment was conducted during 2018 and 2019 seasons, at Sakha Agricultural Research Station, Kaferelshiekh, Egypt. To study the efficacy certain herbicides [Nicosulfuron (Shamshon 75%WG), Flumetsulam (Candy 80%WG), Bromoxynil+ Terbuthylazine (Monester 35%SE) and Nicosulfuron+ Bromoxynil (Scrop 75%WG)] at full rate (alone) (30g, 30g, 500cm3 and 120g /fed.), respectively, and at used rate (75 or 50%) of full rate mixtures with mineral oil at 1 and 2%, beside, Maisterpower 4.53% OD (Foramsulfuron-sodium+ Iodosulfuron-methyl-sodium+ Thiencarbazone-methyl) at full rate (alone) 500cm3/fed., (fed= feddan=0.42 hectare), hand hoeing (twice) and weedy check on weed control, productivity and grain quality. Each experiment was laid out a Randomized Complete Blocks Design.Results revealed that both (Monester and Scrop) at used rate 75%+ min.oil 1% or Maister power at full rate gave more controlling effect on total weeds which was reflected to increase yield and its components, than other treatments in both seasons. Also, previous treatments gave increasing grain yield which was directly correlated with increasing vegetative growth traits, yield components and quality characters of grains compared to other treatments in both seasons.Results indicated that the herbicide and adjuvants selected and relative amount used both of them must be tailored to specific condition of each application, therefore, it could replace the two herbicides (Monester or Scrop) at used rate 75% with min.oil 1% by Maister power at the full rate (alone), to avoid the appearance development weeds-resistant to herbicide, beside, without loosing weed control efficiency and grain yield, its components and quality in maize.

THIS INVESTIGATION was carried out to induce the mutations in bread wheat (Triticum aestivum L) at the Experimental and Research Farm, Faculty of Agriculture, Al-Azhar University. Two wheat geno.types were treated with different concentrations of di methyl sulfoxide and sodium azide (NaN3). The highest grain yield/ plant (81.27g and 80.56g) were obtained from Sids 14 treated with either (di- methyl sulfoxide at 2000ppm) or sodium azide at 6000ppm. The untreated plant Sids 14 gave 39.23g. The variety Sids 14 was more productive than Misr 1 induction of stable promising mutants according to the final results at M2 especially with respect to high grain yield/ plant. In general, Sids 14 was more response to chemicals treatment for 1000 grains weight than Misr 1 and gave higher 1000 grains weight. Sids 14 di methyl sulfoxide 1, Sids 14 DMS2, Sids 14 Sodium Azide1 , Sids 14 Azide2 and Sids 14 Azide3 gave (58.27,55g). The geno.types Misr1 Azide 3 (2, 3 and 6) were short but the genotypes Sids 14 DMS1 (3 and 7) were tall, while the genotypes Sids 14 DMS1 (5 and 6) were very tall in both M1 and M2. In spite of the high 1000 grain weights variety Sids 14 gave the highest grains no./ spike 72, Sids 14 Azide3 and Sids 14 DMS1 giving 88.33 and 87.44 grains, respectively. Mutants Sids 14 Azide3 and Sids 14 DMS1 surpassed the original plants in grain no. spike by 22.68% and 21.44%, respectively. There was a significant and positive correlation between yield and spike no./ plant, spikelet no./ spike and grain/ spike across both varieties and generations. There was a low correlation coefficient between grain yield/ plant and 1000 grain weights (0.016) and the negative correlation between grain yield/ plant and plant height (cm).

SALINITY stress significantly impacts the growth, development and yield of sorghum. Knowledge about the productivity of sorghum under salinity stress condition is lagging, due to the marginally limited information about the physio-biochemical and molecular mechanisms underpinning salinity stress tolerance. The study aimed to investigate the physio-biochemical and molecular mechanisms associated with the differential responses under salinity stress condition in sorghum. To achieve our objectives, the physiological and biochemical salinity stress parameters, including membrane stability index, enzyme antioxidant activities, proline and chlorophyll contents, measured at the seedling stage, were elucidated to identify the salinity stress response status of the genotypes. The quantitative real-time polymerase chain reaction (qPCR) was perform to elucidate the expression pattern of different categories of genes under salinity stress in sorghum genotypes. From our results, enhanced enzyme antioxidant activities, membrane status, increased proline content and lower K+/Na+ concentration under 300mM NaCl stress identified PI 585451 to be the most salinity stress-tolerant genotype. Nevertheless, increased MDA and Na+/K+ level, lower proline, chlorophyll content and antioxidant enzyme activities in PI 585454 marked it to be sensitive to salinity stress. Besides, the transcript expression analysis of different genes, showed an upregulation in PI 585451 than in PI 585454. The results highlighted the differences in metabolic response to salinity stress that may play an important role in the provision of information, required for breeding and development of sorghum genotypes that are tolerant to salinity stress.

TWO FIELD experiments were done at Experimental Farm, Faculty of Agriculture, Menoufia University, Shebin El- Kom, Egypt, during 2018 and 2019 seasons to study the effect of 3 irrigation intervals, i.e., irrigation every 12 (I1), 17 (I2) and 22 days (I3) on growth, productivity and quality of 6 yellow maize genotypes (G), i.e., S.C 178, S.C 176, S.C 168, T.W.C 368, T.W.C 360 and T.W.C 352. The results could be summarized as follows:1- Increasing irrigation intervals from 12 up to 17 and 22 days significantly decreased number and area of leaves and leaves, stem and total dry weight/plant, total chlorophyll, relative water content (RWC), plant height, length and diameter of ear, number and weight of grains/ear, 100 grain weight as well as grain, stover and biological yields/fed, protein and oil % and yields/fed, but significantly increased proline content in leaves in both seasons.2- S.C 168 G surpassed the other genotypes in area and dry weight of leaves/plant, grain yield/fed, crop and harvest indices as well as protein yield/fed. T.W.C 368 G was superior in stem and total dry weight/plant, plant height, ear diameter, no.of grains/ear,100-grain weight as well as stover and biological yields/fed. However, S.C 168 G and T.W.C 368 G recorded the best values of RWC, no.of ears/plant, grain weight/ear, protein% and oil yield/fed as compared with the other genotypes. The highest significant values of proline content and no.of leaves/plant were obtained by T.W.C 352 G and T.W.C 360 G, respectively in both seasons.3- Maize genotypes S.C 168 as well as T.W.C 360 and T.W.C 352 under I2 and T.W.C 368 under either I2 or I3 had the lowest values of relative yield reduction and drought suS.Ceptibility index (< 1), indicating that those genotypes are relatively drought tolerant genotypes compared to other tested genotypes in our experiment condition.
