Abstract

The study was conducted on soil from lower - Kanan project to investigate the effect of clay percentage and typed clay minerals on some mechanical properties of soil. The study dealed with collecting distributed and undistributed soil samples to examine percentage of clay , type of minerals , bulk density , porosity , hydraulic conductivity and shering strength of soil. Also moisture content under different tension was measured .The results showed that clay content in soil was 48% and clay plus silt were 92% . Wide ranges of clay minerals were obtained . The clay minerals were 38% Semictrite , mixture of illite and pallygroscite were 23% , and chlorite 13% and kaolinite 3%.These characterization of clay and clay minerals with 32% of CaC03 result in compacted soil with variable bulk density, porosity, moisture content and low hydraulic conductivity and high shering strength The soil contained a hardpan layer was suitable for irrigation and drainage vacillates. Such soil was not suitable for cultivation under these condition because of the poor root penetration, low water movement and low oxygen diffusion.

Abstract

A Field experiment was conducted during the season 2000-2001 at Abu-Ghraib experiment station , ministry of Agric, Baghdad to study the effect or interaction between K-fertilizer and spraying with Fe and Mn'on vegetative growth of wheat (Triticum aestivum L.), cv. Abu-Ghraib -3. Potassium was applied at a rate of (0, 60 , 120 kg K.ha"1) as K2S04 - Three concentrations of Fe and Mn were used as foliar fertilization. The levels of (0 , 50 and 100 mg Fe.L"1) as FeSO„.7H20 and (0 , 25 and 50 Mn.L ) as MnSO,,.H,0 were used as sources for Fe and Mn, respectively. Foliar fertilizers were applied at three stages of "growth, once at elongation , twice at elongation and booting and three times at elongation , booting and flowering stages. The results indicated that the application of K , Fe and Mn significantly increased the dry weight and uptake. Increasing dry weight was mainly related to the application of potassium fertilizer (16.9 gm.planf1) in spite of the high level of available potassium , and secondary to the iron application (16.46 gm.plant"1). The high response of wheat was at 120( kg K.ha"1, 50 mg Fe.L" and 25 mg.L as foliar nutrition at elongation and booting stages (18.7 g.plant" ).

Abstract

Four subspecies of maize; saccharata, indentata, indurata and everta were intercrossed. This was to study the direct effect of pollens on seed characteristics (xenia). The result obtained showed that xenia was not exist in the Fl seeds of those crosses for pollens had no direct effect on any seed trait studied. However, the female cytoplasm controlled all seed traits unless hybrid vigour or dominance appears. That was attributed to the fact that female contributes with 2 nuclei and the pollen with one nucleus through fertilization. A maximum of 51.6% hybrid vigour in seed weight was found in saccharata when used as female, while a negative heterosis (- 25.6%) was found in seed weight when everta used as female?The inheritance of colour and shape of Fl seeds was controlled by the female cytoplasm, but in some crosses it gave a midparent value. Meanwhile, dent shape was similar in inheritance to that of colour and shape of seed. The saccharata subspecies gave always a dented seed when used as female in regardless of pollen, while the other three subspecies (when used as female) and crossed by saccharata gave either flint trait or midparent. It was concluded from this work that traits of Fl seeds are under female cytoplasm control unless heterosis or dominance appears. That is to say, hybrid vigour could appear immediately (if exist) on the Fl seeds of the crossed female and not the xenia effect.

Abstract

To investigate the effects of planting season and date of harvest on sunflower seed quality.and viability, field and laboratory experiments were carried out at the farm of Field Crops Research Sta./ Agric. Res, Center. Five A-line inbreds, and one R-line were crossed to produce five hybrids, grown and compared. Results revealed that spring and fall plantings gave; 18.1% and 27.3% seed moisture at harvest (SMH), 79% and 88% first count germination (FCG), 77% and 81% field emergence (FEP), 90% and 91% emergence in cold test (ECT), and 17 and 19 mg seedling dry weight (SDW), respectively. Meanwhile, harvesting seed at maturity and one month later gave; 31.8% and 13.5% (SMH), 86% and 80% (FCG), 82% and 72% (FEP), 91% and 90% (ECT), and 19 and 17 mg (SDW), respectively. Inbred and hybrid seeds responded differently to planting season and date of harvest. Accordingly, we could manage which inbred or hybrid to be grown or harvested. The results showed that (ECT) was not recommended to test seed viability, whereas (FCG) and (FEP) gave similar trends in their response to planting season and date of harvest. This recommends the use of either tests to judge seed viability instead of common germination test and (ECT). The maternal effect of cytoplasm of all inbreds have increased (SDG) according to a preprogramed organ weight/ growth rate relationship. Seeds of inbreds and hybrids gave average (FEP) of 83% and 81% in the spring, and 82% and 72% in the fall, respectively. Interactions of genotypes by planting season, and genotypes by date of harvest were significant and that indicates the different response of genotypes to both variables studied.
