Abstract: Growing consumer demand for year-round supply of fresh strawberries in Ontario justifies cropping of dayneutral strawberry to extend the growing season. Currently they are grown on about 20% of the strawberry acreage in Ontario, and the harvest season has been expanded from six weeks to six months. This study assessed current dayneutral strawberry production technology, calculated cost of production, and evaluated effects of varying sale prices, channels of sale and yields on returns. The data were grower-generated and collected through paper-based surveys of existing dayneutral strawberry growers. The surveys were conducted in 2011 and 2012 in southwestern Ontario. Study results demonstrated that dayneutral strawberry production was labor and resource-intensive, but an economically viable enterprise. The net revenue was channel-of-sale and yield dependent.

Abstract: The objective of this study was to investigate the effects of strain and non-genetic factors on egg qualities and carcass characteristics of indigenous Guinea fowl. The study was carried out at the Poultry Section of the Department of Animal Science Education, University of Education, Winneba, Mampong-Ashanti, Ghana, from 2014 to 2016. Four strains of local Guinea fowls; namely Pearl, Lavender, White and Black were used. Three non-genetic factors were considered; season of hatch, generation and sex of bird. Data were collected on 603 local Guinea fowls for the study. Data were analysed using the General Linear Procedure (GLM) of SAS. Results obtained showed that egg weight was significantly (p<0.05) affected by generation. Parental generation had higher value (37.9±3.98) than the first filial generation (37.64±0.93); however, strain and season had no significant (p>0.05) effect on egg weight and hatch weight. Generation had significant (p<0.05) effect on yolk weight. Parental and first filial generations had 13.7±0.24 and 13.2±0.21 yolk weights respectively. Haugh unit was significantly influenced by strain; white had highest (79.04±2.49) Haugh unit, followed by lavender (77.67±2.03), black (76.51±2.49) and pearl (71.14±1.2). Generation had significant (p<0.05) influence on live and dressing weights. Sex had no significant (p>0.05) effect on head, neck and shank weights. The interaction of sex and Strain had significant (p<0.05) influence on live, heart and intestine weights. Generation had no significant (p<0.05) effect on carcass characteristics. Strain had significantly (p<0.05) influence on moisture and carbohydrate. In conclusion, the strains and non-genetics factors (sex, season and generation) influence the egg and carcass qualities of indigenous Guinea fowl, hence the effects of these factors must be considered in genetic selection of indigenous Guinea fowls.

Abstract: The objective of the study was to evaluate the efficiency of biofertilizers in improving wheat yield, yield components, and nutrients balance in soil. Local and imported biofertilizers were applied in a field experiment at Erbil, Iraq for the season 2016-2017. The experimental design was Randomized Complete Block Design (RCBD) with four replicates. The experiment consisted of five treatments: T1 = Natrusoil (Commercial Biofertilizer) only, T2 = Natrusoil + 25% Chemical Fertilizers (CF), T3 = Local Biofertilizer B1 + 25%CF, T4 = Local Biofertilizers B2 + 25%CF, and T5 = CF as a Control (Recommended: Urea = 260 kg/ha, DAP = 180 kg/ha). Management practices in soil preparation and crop management followed the common and general procedures. Most test biofertilizers significantly increased yield of wheat grain or yield components. Maximum significant grain yield was obtained from biofertilizers treatments Natrusoil+25%CF (4.659) and B1+25%CF (4.691) as compared with the Control (3.987 kg ha-1). The increase in yield was in the range 17-18%. The application of biofertilizer resulted in a positive effect on nutrients balance in the soil at the end of season regardless of type of biofertilizrs as indicated by the increase in levels of NH4, NO3, P, and K. Among the benefits of using bioferilizers is the reduction in cost. The reduction was 47% in using the imported Natrusoil + 25%CF increased to 72% when using the Natrusoil alone.

Abstract: This survey aims a better knowledge of the extent of the culture and the farmer fashion of management of the species of Amaranthus spp cultivated in Burkina in order to propose adequate methods of management, improvement and valorization. For that, a prospecting collects coupled of an ethnobotanical investigation have been achieved in the three climatical zones of the country. The prospecting collects permitted to constitute a collection of ninety-nine (99) accessions. The ethnobotanical investigation has showed that the culture of the amaranth is in net progression and is practiced in all climatical zones of the country. The producers who are mostly men (64.45%) use the agromorphologic and organoleptic characteristic in the designation of the cultivars. Eight (08) morphotypes has been identified among witch green morphotype is the most cultivated. More than 60.43% of the producers get the seed by selection according to the needs of the consumers against only 23.02% by gift and 16.4% by purchase to variable prices from CFA 50 (0.076 €) to 3500 (5.34 €) for a conditioning from 0.5 to 1kg. Furthermore seeds are often preserved in mixture with the ash, in bottles, in cans, in canaries or in sachets.

Abstract: In order to find a new technique for breeding super high varieties of wheat s, according to the theory that rare gene activity will be caused then make new genotypes, and promote branch and evolution of species in strange radiation fields, and the principle of mutagenic breeding, In order to increase crop yield, it is necessary to improve the physiological metabolic intensity of plants and improve the hybridization advantages in breeding. In order to improve the hetero sis of hybrids, there must be large genetic differences between parents and close to extreme types as far as possible. However, for crops with little genetic difference among wheat and other varieties, it is difficult to develop new varieties with high yield by conventional hybrid breeding. Therefore, by means of radiation mutagenesis, one or two parents of the hybrid can be mutated, which can improve the genetic difference between the parents and enhance the hetero sis of the hybrid parents. For this, we call it "new technology". In this paper, the technology of breeding high varieties directly in progeny with various radiation factors and of F0, F1, F3 by irradiation is called "classical technique.” By comparing "new technology" with "classical technology", this paper introduces the practice and application prospect of the new technology, and introduces the characters, advantages and disadvantages and application value of the super-large grain wheat variety "Long Nan 71a" cultivated by the new technology.
