Effect of Tillage and Planting Methods on the Soil Properties, Grain Drill Performance, and Wheat Yield

The effect of conservation tillage methods and seeding machines on the soil physical properties, performance of grain drill, wheat yield, and wheat yield components was evaluated. The research was conducted in a split block experimental design with twelve treatments and four replications, and a local wheat variety （Shiraz） was planted in this study. Main plots were tillage methods including： （1） primary tillage using moldboard plow without moldboard; （2） primary tillage with disk harrow; and （3） primary tillage with chisel plow. Subplots were grain drill types including： （1） planting with Taka grain drill without furrower; （2） planting with Taka grain drill having furrower; （3） planting with Hamadan Machine Barzegar grain drill having furrower and runner opener; 4） planting with grain drill having ripple opener. Parameters including mean weight diameter of clods （MWD）, soil bulk density, uniformity of seed planting depth, seed distribution uniformity, seed emergence, crop yield, and crop yield components were measured. SAS software was used to analyze the collected data and the method of benefit to cost ratio was used to compare the treatments from the economic point of view. Results indicated that tillage method had no significant effect （P = 0.05） on the measured parameters. Plant per unit area, seed emergence, uniformity of seed planting depth, and MWD were significantly affected by the grain drill type （P 〈 0.05） while, the type of grain drill had no significant effect on the rest of measured parameters. Taka grain drill without furrower had the highest uniformity of planting depth and proper soil MWD, and grain drill with ripple opener had the highest seed emergence and plant per unit area. Interaction between tillage methods and grain drill types affected the soil MWD, seed emergence, and crop yield （P 〈 0.05） in such a way that the combination of primary tillage with disk harrow and planting with grain drill having ripple opener provided the highest crop yield.

Effect of Self-fertilization on Performance, Breeding and Germplasm Management of Four Local Faba Bean Cultivars

Faba bean is self- and cross-fertilized species. The consequences of self-fertilization are important factors determining the germplasm management in such species with levels of heterogeneity and heterozygsity. Effects of self-fertilization on floral, yield and yield components characters were evaluated by comparing two levels of selfing, produced in bee-proof cages, in open-pollination at two locations in Sudan. Selfing process results in no significant differences in yield and yield components within each cultivar. Autofertile lines with reduced partial dependence on insects for seed set could be produced. Spatial isolation should be used to maintain the genetic purity of such lines. An alternate strategy for entries multiplication should focus on increasing heterozygosity and the maintenance of cross-fertilization inside the entries to prevent contamination with foreign pollens. Our results follow the previous knowledge on faba bean genetic resources conservation and management.

Evaluation of the Nutritional Supplement VIUSID Vet Powder on the Productive Behaviour of Sows and Boars

The objective of this research was to evaluate the effect of administering VIUSID vet powder on the productive behaviour of sows and the quality of semen of boars. Two experiments were conducted on farms in the province of Sancti Spiritus, in the central region of Cuba. One was with sows, starting 21 days before parturition until weaning, and another was with boars in directed mounting. Each sow received 10 grams of VIUSID vet powder everyday, mixed with food, from 21 days before the probable date of farrowing and until weaning （33-day lactation period）. In the boars, the treatment consisted of administering 10 grams of VIUSID vet powder with feed, once a day for 6 weeks （week 1 to 6）; from week 7 onwards, the supplement was suspended. Results showed that, supplying VIUSID vet powder significantly improved the principal post-partum productivity indicators and significantly reduced diarrhoea and administration to boars in production for 6 weeks, which has improved spermatic motility and does not affect the other variables representative of the quality of the semen.

The Effect of the Supplemental Different Levels of Anise Seeds （Pimpinella anisum） in Diet on Broiler Performance

This experiment was conducted at the poultry farm, poultry research station, state board of agriculture research, ministry of agriculture to study the effect of supplemental anise seed on broiler diets. A total of 640 of one-day old unsexed broiler chicks （Cobb） were used in this study. They were randomly distributed to four treatments. Anise seeds were supplemented at the levels of 0.2%, 0.4% and 0.6% compared with the control group for 49 days. The results showed： there was a significant （P 〈 0.05） increase in the rate of body weight for the two treatments 0.6% and 0.4% of the anise seeds compared with 0.2% and control treatments, body weight gain take the same direction, like in body weight, the highest treatment was 0.6% followed by treatment 0.4% as well as the feed consumption has increased in these treatments than in 0.2% and control treatments, so about feed conversion ratio the treatment 0.6% of the anise seeds recorded the best feed conversion ratio compared with other treatments. Significant decreased in mortality and significant increased in production index by increasing the level of anise seeds in feed. Dressing percentage increased significantly for all treatments using anise seeds and treatment 0.6% recorded highest dressing percentage, from the other hand percentage of abdominal fat decreased significantly by increasing anise seed levels and no significant difference in the percentages of liver, gizzard and heart were recorded in this study. About carcass cuts, the weights of primary cuts （thigh, drum stick, breast） relative to body weight recorded significant increase in the treatments using anise seeds at the expense of secondary cuts （neck, wings, back）. There was a significant decline （P 〈 0.05） for total bacterial （E. coli and Staphylococci） in small intestine in all level of anise seeds （0.2%, 0.4%, 0.6%） in ration while the decline of two types of bacteria in colon recorded in 0.4% and 0.6% treatments compared with 0.2~/0 and control treatments. Conclude from this study the possibility of using anise seeds at all levels used in the experiment and the best level that can be used to get the best performance of the positive results of broiler chickens is 0.6%.
