  • ABSTRACT

An experiment conducted at the Qlyasan Agricultural Research Station,- Faculty of Agricultural Sciences, during the fall season of 2011- to study the response of four maize genotypes (SC 301, Mar Ket , Talar and Cadiz) to the temperature and light intensity under field and greenhouse conditions. Obtain all genotypes from different sources (IRAN, Turky, Local and, Turky). Randomized complete block design (RCBD) and complete randomized design (CRD) were used with four replications for field and greenhouse experiments , respectively. Light intensity measured by PHYWE-type- LUX meter. Shading used for diminishing over heat. Light- bulbs used for balancing light interception inside the greenhouse . Result showed significant differences among maize genotype under field conditions in their response to the temperature and light intensity in studied vegetative growth traits except plant height and chlorophyll content which measured in post-silking. There were significant differences in accumulated numbers of Crop heat unit among genotypes, in which genotype SC 301 needed minimum numbers of Crop heat unit (2121.6) , while genotype Talar needed maximum numbers of Crop heat unit (2346.625) and there were differences in the distribution pattern of the accumulated heat units on the growth stages of the genotypes. There were significant differences among four maize genotypes in the rate of leaf appearance across the growth season, and in the number of Crop heat unit required for phyllochron in different stages of growth , and the superiority was to genotype Talar compared to other genotypes. The significant exceeding of genotype Talar also was in Leaf Area Index due to larger numbers of leaves.

Effect of plant density on seed yields and it is components of two pea (Pisum sativum L.) cultivars under rainfed condition in Sulaimani province. Jornal of karbala for Agricultural Science , Volume 6. Number 1. December 2019 ISSN: 2309-5199 EISSN:2616-6933 .

ABSTRACT

This study was carried out to investigate the response of two cultivars of pea (Markerbsen and Zuckerbsen) to three plant densities (20, 40. And 80 plant/m2) under the rain fed condition in Sulaimani province, during the growing seasons of (2014-2015 and 2015-2016) .At 50% anthesis, the plant height and above ground dry matter accumulation, and at harvest the yield and yield components ({number of branch per plant, number of pod per plant, number of seed per pod, number of seed per plant, seed weight per pant (g/), 1000 seed weight (g) , biological yield (g), seed yield (kg/ha) and harvest index (HI) } were evaluated. The results showed no significant effects of cultivars, plant densities and their interaction on plant height, while, the cultivar of Zuckerbsen was significantly accumulated above ground dry matter compared to Markerbsen and at lowest plant density (20 plant/ m2) followed by (40 plant/ m2). Number of branch per plantو number of pod per plant, number of seed per pod, number of seed per plant, biological yield had not affected by both cultivars and plant densities. However, the highest and significant weight of seed ,1000 seed weight, harvest index (HI) were obtained in first growing season by Zuckerbsen cultivar at 20 plant/m2 compared with Markerbsen cultivar at (40 and 80 plant/m2) densities and second growing season . The highest seed yield was obtained by Zuckerbsen cultivar in both growing seasons at plant density of (80plant/m2) with value of 3159.95 kg/ha) in first growing season and value of (2873.65 kg/ha) in second growing season followed by Markerbsen cultivar in first growing season with value of (2599.52 kg/ha) at 80plant/m2) compared to other plant densities this mean both cultivar performed better in first growing season with higher rainfall and lower temperature during pod development compared to second growing season. This study suggested Zuckerbsen cultivar and plant density of 80plant/m2 for Sulaimani province

Optimizing Phosphorus Fertilization Promotes Dry Matter Accumulation and Phosphorus remobilization in Oil Seed Flax (Linum usitattissimum. L.). Journal of Zankoy Sulaimani ,Volume 21. Page 29-36 . ISSUE: 10742 .

ABSTRACT

This experiment was carried at Qlyasan Research Station. Faculty of Agricultural Sciences, University of Sulaimani, during 2016-2017 to study the effect of four levels of phosphorus fertilizer in the form of P2O5 (0 control, 100, 200 and 300 kg P2O5ha-1) on two oilseed flax varieties (Poland and Syria local) dry matter and Phosphor accumulation and their translocation from source to sink . Results showed that Poland variety with the 200kg P2o5 ha-1 in all studied parameters significantly being higher than Syria local, and other levels of P2O5 fertilizer. Compared to control 200kg P2O5 increased DM accumulation at 50% anthesis by (44.48 and 27.04%), DM translocation efficiency by (24.46and 38.19% ),Contribution of leaves DM to final grain by (53.57 and 44.060%), P accumulation in vegetative tissues at 50% anthesis by (69.59 and 81.65 %), P translocation efficiency by (51.85 and 70.02%), leaf P contribution to final grain by (50.69 and 73.63%), also at maturity increased biological yield by (27.16 and 29.72%), and increased grain yield by (20 and 27%) for Poland and Syria local respectively, with no significant increment above that level. In both varieties at 50% anthesis the leaves DM were increased and reached peak at 200kg P2O5ha-1 but as the plant reached maturity the leaves DM significantly lower by ten times than stem DM+NG. These results suggest that 1.The leaves in oil seed flax are the major DM and P contributor to grain after anthesis whereas the stem and NG are the stronger demand for DM and P post anthesis.2. Variety of Poland under the 200kgP2O5 ha-1 could be suitable for grain yield under rainfed condition in Sulaimani province.
