Water deficit is one of the main limiting factors affecting plant growth. Selection in water-limited environments can result in populations or species with improved response to drought. Water deficit decreases yield and quality, therefore, it is important to identify genotypes that are tolerant to deficit irrigation conditions. In this study, the water-deficit tolerance of 59 pepper-inbred lines was determined. Experiments were conducted in a growth chamber and under field conditions (Şanlıurfa) with a control (100% full-irrigation) and water-deficit treatment (50% irrigation). Fruit weight, fruit length and number of fruits were recorded. Pepper lines 1900, 896 A-W, 74, 760, 1560-W, 912 A-W, 405-A, 953-W, 226, 1105-W and 441 were identified as the most tolerant to water deficit conditions. Present findings revealed that these pepper lines could be used to develop cultivars that have satisfactory yield under water deficit conditions.

This study was carried out to determine the effect of non-genetic factors on growth and reproductive traits in Saanen goats. For this aim, total of 274 Saanen goats and kids were investigated for growth and reproductive traits in South Marmara Region of Turkey. Fertility parameters were evaluated during two reproductive years. Saanen kids were measured from birth to 6 months of life. The average live weights at birth, weaning, 60th, 90th, 120th and 180th days of age were calculated and determined as 3.05±0.04kg, 11.80±0.27kg, 12.26±0.08kg, 14.20±0.32kg, 17.41±0.45kg, 25.01±0.65kg, respectively. The effects of sex and birth type on live weights until 90th days of age; maternal age only on birth weight; month at birth on all of investigated days were found significant statistically. The pregnancy, birth rate per pregnancy (BRP), birth rate per mating (BRM), infertility, abortion, kidding rate (single, twin or triplet), survival rate (until weaning), number of kids per parturition (NKP), number of kids per mating (NKM) were found; 92.98%, 85.07%, 91.25%, 7.02%, 8.75%, 36.12%, 49.00%, 14.88%, 89.13% and 1.74±0.06, 1.42±0.07 respectively. The effects of maternal age on all rates (out of BRM and abortion rate); the year on birth, abortion, single kidding rate, survival rate and NKM were found significant for reproductive traits. The advanced reproductive performance and rapid growth rates were observed in Saanen goats. Environmental factors such as age, year, sex, birth type and month at birth were found significant on some growth and reproductive traits in Saanen. So consideration of these factors could be useful as a selection criteria in dairy goat breeding.

This study was carried out in greenhouse and laboratories of Department of Horticulture (Faculty of Agriculture, Ordu University, Ordu, Turkey) in 2013-2014 production seasons in Ordu ecological condition. Commercial garden cress standard seeds were used as plant materials. Plant densities were calculated upon the seed quantity spread on 1 m2, and seeds were sown for 1.0, 1.5, 2.0 and 2.5 g per m2. Peat: perlite mix prepared in proportion of 3:1 was used as the growing medium and filled in 50×16×14 cm sized plastic pots. The garden cress plants were harvested on the 45th day after seeding. The yield, leaf petiole length, leaf length, leaf width and chlorophyll content of the harvested plants were determined. It has been determined that quality parameters vary depending on plant density and varieties. The highest plant yield was obtained from “BT Bu-ter” garden cress variety with 2.489.2 g/m2. The plant yield in different plant densities was increased in the rates varying between 3.31% and 8.25%. The increasing plant densities caused an increase in yield but negatively affected the leaf quality in terms of both length and chlorophyll content. Leaf width, leaf length, leaf petiole length and chlorophyll content were decreased depending on the increase in plant densities. Based on the information obtained, it was considered useful to choose a plant densities based on the variety and growing season according to the growing purpose.

Genetically modified (GM) crops are being planted at large scale worldwide. In most of the countries, GM crops are processed into livestock feed. The land is used for cultivation of GM plants has been increased in recent years; in 2012 GM plants were grown on over 170 million hectares in 28 countries by 17.3 million farmers and extended to 185.1 million hectors in 2016 worldwide. GM plants have been used as feed for animals and the number of studies has proved their safety for animal and public health. This paper reviews the possible effects of GM crops on livestock, poultry, and aquatic animals by reviewing different type of studies, in which parameters such as performance, reproductive and health assessment were investigated. The most of peer-reviewed papers evaluating the effects of feeding animals with transgenic crops were based on GM plants with improved agronomic traits i.e. herbicide-tolerant plants and pets-tolerant plants; however, in some cases GM plants with boosted nutritional properties assessed. In most experiments, either Bt (Bacillus thuringiensis) maize, Roundup Ready (RR) soybean or both fed to animals. Measurable differences in various parameters were mostly observed in Bt maize and soybean fed separately or simultaneously to animals. In this review, scientific studies showing the effects of the use of GM products in the nutrition of domestic animals on performance, health and reproductive parameters are investigated.
