Abstract

A field experiment was carried out during the growing seasons of 2016/2017 and 2017/2018 at Al-Zubair district, Basra Province, to study the response of three varieties of oats (Ganzania, Shafaa and Carrolup) to mineral and bio fertilizer, nitrogen-fixing bacteria (Azotobacter chroococcum), phosphorus solubilizing bacteria (Pantoea agglomerans) and potassium solubilizing bacteria (Bacillus subtits and Bacillus mucilaginosus) were used in seven levels: (B0 = control, B1 = mineral NPK, B2= NPK bio fertilizer, B3 = N bio. + mineral PK, B4 = NP bio. + mineral K, B5 = NK bio. + mineral P and B6 = PK bio. + mineral N) on yield components, grain yield and  the concentration of NPK nutrients in grains and vegetative parts. Randomized complete block design RCBD was used which arranged according to split-plot design with three replicates, the fertilizers were placed on the main plots, while varieties were at the sub-plots. The results showed that fertilization with bio-fertilizer NPK (B2) increased significantly the studied traits (NPK% concentration in grains and vegetative part, panicles/m2, grains/panicle, 1000 grain weight, grain yield, biological yield and protein yield). For the two seasons, while treatment B2 gave an increase in grain yield of 189.96 and 197.3%, and the biological yield 112.92 and 137.36% compared with control treatment for the two seasons respectively. Varieties differed in most of the studied traits, Ganzania resulted in highest grain yield in the first season (5.774 t/ha) while Shafaa gave the highest yield in the second season (8.691 t/ha). The interaction of Ganzania with B2 and gave the highest grain yield (8.429 t/ha) in the first season, while in the second season all varieties showed significant superiority with B2 and produced the highest grain yield, biological yield and protein yield without significant difference between them. The study recommends the use of bio-fertilization that containing various microorganisms (nitrogen-fixing and phosphorous  potassium solubilizing bacteria) and it is preferable to grow Ganzania or the Shafaa variety.

Abstract

The present research is carried out at the Farms of Agricultural Secondary School in AL Salamieh city, Hama Governorate, Syria, during the season 2015 to evaluate the productivity of three sweet corn varieties; one was local variety, Faihaa1; and two Ukrainian varieties; Randevo F1 and Snekofa Karaliva F1 under the effect of different planting dates (1st and 15th April) in order to determine the best variety and the most suitable planting date in spring season. The results showed that the grain yield and yield components of Faihaa1 variety were higher than that of Randevo and Snekofa Karaliva in the first planting date (1st April). The increase of grain yield recorded were (3.38-2.86-ton/ha), and fresh ears yield with husks recorded were (1.88-0.58-ton/ha) respectively. Also, the results showed that there was significant increase in number of ears per plant, number of grains per ear and ear grain weight of Faihaa 1 variety compared to Randevo F1 and Snekofa Karaliva F1. And grain yield and yield components of Faihaa 1 were higher than Randevo F1 and Snekofa Karaliva F1. The highest grain yield was at the beginning of April for all varieties, and the fresh grain yield recorded was (9.01) ton/ha. The fresh grain yield and other productivity characters decreased on mid-April for all varieties. The results showed that there was significant increase in the productivity characters in Faihaa 1when it was planted at the beginning of April.

Abstract

The experiment was conducted at Al Muriea Station, Der Al Zur Agricultural Research Center, (GCSAR), Syria, during 2010/2011 season, in a loamy silt soil, the soil composed of 40 and 32% of clay and silt, respectively. NPK contents were 4.1:10.9:121.5 respectively, while boron content was 1.56%. This study aims to study the effect of boron fertilizer application method and level on the production and quality traits of two sugar beet varieties, one was monogerm (Scorpion), the other was multigerm (Nadir). Split plot design with three replications was used. Boron fertilizer was appointed in the main plots, but the varieties were allocated randomly in the sub plots. Four levels of ground boron fertilizer were added to the soil (as Borax 11%) (5, 10, 15, and 20 Kg Borax/Ha), and two levels of spray boron fertilizer (as Borax 11%) were sprayed on the leaves (10, and 20 Kg Borax/Ha), besides the control treatment, the total treatments of boron addition were six. The results showed that ground boron application has no significant effects on the studied traits, because of the high content of boron in the soil 1.56 ppm. The results exhibited a significant effect of the spray boron on sugar and root yields (ton/ha).

Abstract

The field experiment was conducted at Al Mray’eyh Research Station, Scientific Agricultural Research Center of Der- Al Zur (NE Syria) during 2009/2010 and 2010/2011 seasons, to study the effect of two methods of irrigation (sprinkler, furrow) and five levels of nitrogen fertilizers (0, 60, 120, 180 and 240), on technological and production traits of three sugar beet varieties, i.e. Dita, Reda, and Nadir in summer time. The experiment was sown in August. A split split plot design was used with four replications. The results exhibited that the addition of 180 pure unit of nitrogen achieved the best technological and production traits. Dita monogerm variety surpassed the other varieties in most of the technological and production characters. It is recommended the sprinkler irrigation, because it increased sucrose percentage (16.2%) and root yield (73.7 ton/ha), as compared with furrow irrigation (15.9%, 67.2 ton/ha) respectively, besides sprinkler irrigation saves water consumption about 20% as compared with furrow irrigation method.
