A field experiment was conducted during winter season of 2014-2015 in a private farm near AL- Khalidiyah district of west of Ramadi city 43° longitude and 33° latitude, to in vistigate effect of sowing date (10th Oct, 20th Oct, 30th Oct and 9th Nov) and cutting date (45, 60, 75 day from sowing) in some of growth characteristics, fodder yield and quality of oat (cv. Shofan 11). Split-plot arrangement was used in RCBD with three replicates. Sowing dates occupied the main plots, while the cutting dates occupied the sub-plots. The results were summarized as follows: Cutting date after 75 day from sowing was superior in most traits in first cut; however, plant height 87.66 cm, number of leaves 6.97 leaf plant-1, stem diameter 5.40 mm, fresh and dry weight of fodder 46.58 and 6.27 ton. ha-1 respectively, As for second and third cutting dates, the first date was superior in most traits under study (e.g. plant height, number of leaves, stem diameter and fresh fodder) their averages were 21.90, 19.90 ton. ha-1 and dry fodder 2.69, 2.72 ton. ha-1 for the first and second cut respectively.
The sowing date 10th Oct in most studied traits for the three cuttings. As for the two way interaction between the cutting dates and sowing dates, plants sown at 10th Oct and cut after 75 days in most of studied traits e.g. number of leaves, stem diameter, fresh and dry fodder where the means were 7.46 leaf plant-1, 5.99 mm, 57.49 ton ha-1 8.29 ton ha-1 in first cut. Plants sown at 10th Oct and cut after 45 days was superior in plant height, number of leaves, stem diameter, fresh and dry weight which recorded 69.90, 71.90 cm, 5.26, 4.63 leaf plant-1, 5.03 and 4.52 mm, 28.78, 28.68 ton ha-1, 3.25 and 4.30 ton ha-1 for the second and third cut.

A field experiment was carried out in loamy silty soil during the spring and autumn seasons of 2013 in Anbar governorate/ Al-Khalidiya district that located on 43° longitude and 33° latitude in order to know the effect of four sowing date in spring season which included (13th March, 10th April, 20th April and 30th April), while the autumn season included (10th July, 20th July, and 30th July) which have occupied the main plots. However, the plant densities have occupied the sub plots, which were (D1-133333, D2-100000, D3-80000 and D4-66666 plant.ha-1. The experiment has been carried out in split plot arrangement in RCBD for three replications. The results were summarized as follows:
The lower plant density (D4) was superior in number of leaves in plant in the two seasons, while the plant density D3 in spring season gave highest average of leave area. For the stem diameter, the plant density D4 was superior in both seasons. As for yield and its components, the plant density D2 was superior by giving the highest average for number of pods in plant and did not show any significant differences in autumn seasons for this trait, while in number of seeds in pod did not show significant differences in both seasons. In 100-seed weight, there were no significant differences in spring season while the plant density D3 gave highest average for this trait. In the yield (ton.ha-1), the plant density D2 was superior in giving highest average in spring season and low density D4 in autumn season. Sowing date did not show significant effect in number of leaves in plant in spring and autumn season and in leaf area and stem diameter. Sowing date gave significant differences; however, the date 30th July gave highest average for this trait in autumn season, while the date 31st March in spring season gave the highest average of stem diameter. The date 10th July in autumn season gave the highest average in the two seasons, while in 100-seed weight and seed yield, the date 31st gave the highest average for the both traits while did not show significant differences and for the same traits in autumn season. The interaction has affected in most traits except leaf area and number of pods in plant and number of seeds in pod in autumn season. As for 100 seed, weight did not show any significant differences in spring season. In seed yield (ton.ha-1) did not show any significant differences between study factors in both seasons.

Five Genotype of maize were used in this study were planted in autiem seoson of 2009 by using arandomiz complete blook design with three replication . The aim of this study was study the effect of sowing dates on yield and yield components of five maize genotypes. Results showed that sowing plants on 30th july give the highest earlength (23cm ), row number perear( 18 row ) weight of 1000 kernels ( 325 gm), and total grain yield (11.5 t / ha ) . grain yield per hectare ( 11.5 t/ ha ) by sowing during 30 July.

Field experiment was conducted at Kadisaea Governorate to investigate effect of three swing rates (100, 140 and 180 kg. ha) on growth and yield of four rice cultivars (Anber- 33, Anber Menathera, Anber Baghdad and Anber Furat).
The results indicated that Anber Baghdad C. V. gave significant increment in plant height, number of panicles per m2, weight of 1000 grains and yield. The cultivar of Anber Menathera gave largest flag leaf area and highest number of grains per panicle.
Sowing rate (180 kg. ha-1) superior in no. days (planting to 50% flowering), FLA (Flag Leaf Area), No. panicle per m2, which rwflected in highest yield.
Data showed significant interaction between sowing rate and cultivars, and that increasing of sowing rate of CV. Anber Baghdad to 180 kg/ ha, encouraged the plant to posses highest No. panciles/ m2 No. grain/panicle, weight of 1000 grain, so these all reflect in highest yield.

Abstract
A field trial was conducted at the field crop station of IPA Agricultural Research Center in Abu-Ghraib during the autumn seasons of 2000 and 2001. The objective was to study the effect of sowing dates on yield and yield components of two maize genotypes. A split plot arrangement in a randomize complete block design with three replications was followed. Planting dates (1st , 15th and 30th July) were assigned in the main plots, Where as the two genotypes (IPA 3001 and Buhooth 106) were assigned to the sub plots. Results showed that sowing plants on 15th July gene the highest ear length (18.3 cm), row number per ear (17.3 row), weight of 1000 kernels (346.7 gm) and total grain yield (9.3 t/ha). Results also showed that the hybrid IPA 3001 gave the highest ear length (18.9 cm), row number per ear (17.7row), weight of 1000 kernels (341.7 gm) and total grain yield (9.6 t/ha). Where as the lowest values of the above mentioned characteristics were found in Buhooth 106 plants. The hybrid IPA 3001 plants produced the highest grain yield per hectare (10.4 t / ha) by sowing during mid July.
