Background and Objective: Selenium (Se) is an essential plant micronutrient and has been repetedly shown to enhance crop growth and crop tolerance to abiotic stresses when applied in trace amounts. However, physiological responses of different plants vary significantly to the Se fertilizer application. The aim of this study was to investigate the effect of Se application on yield and quality parameters of peanut under field conditions. Materials and Methods: A pot experiment was conducted where Se fertilizer was applied (i) To soil at 5 different doses, (ii) As folier fertilizer or (iii) Via seed soaking at 4 different doses. Two years field experiments were conducted under East Mediterranean conditions of Turkey. Results: The yields were significantly increased by all types of Se applications. The highest yield (6130 kg ha−1) was obtained from foliar applications made 40 days after flowering. Increasing doses of Se increased 100 grain weight but oil, protein and nitrogen content of grains were not affected. Conclusion: Two years experiment clearly showed that external Se supply to peanut (all methods tested) increased yield formation in East Mediterranean conditions of Turkey. Here, particularly foliar application (3% sodium selenite) of Se 40 after flowering seems to be most effective way for its application. © 2017 Seyyid Irmak.

Effective breeding programs based on genetic diversity are needed to broaden the genetic basis of rice (Oryza sativa L.) in Turkey. In this study, 81 commercial varieties from seven countries were studied in order to estimate the genomic relationships among them using nine inter-primer binding site (iPBS)-retrotransposon and 17 simple-sequence repeat (SSR) markers. A total of 59 alleles for the SSR markers and 96 bands for the iPBS-retrotransposon markers were detected, with an average of 3.47 and 10.6 per locus, respectively. Each of the varieties could be unequivocally identified by the SSR and iPBS-retrotransposon profiles. The iPBS-retrotransposon- and SSR-based clustering were identical and closely mirrored each other, with a significantly high correlation (r = 0.73). A neighbor-joining cluster based on the combined SSR and iPBSretrotransposon data divided the rice varieties into three clusters. The population structure was determined using the STRUCTURE software, and three populations (K = 3) were identified among the varieties studied, showing that the diversity harbored by Turkish rice varieties is low. The results indicate that iPBS-retrotransposon markers are a very powerful technique to determine the genetic diversity of rice varieties. © FUNPEC-RP.

The use of organic materials as a source of nutrients on agricultural lands ameliorates soil physical properties as well as being an environmentally friendly way of disposing of their wastes. This study was conducted to determine effects of three organic materials (poultry litter, cattle manure, leonardite) on yield and nutrient uptake of silage maize. Poultry litter and cattle manure were applied based on phosphorus (P) or nitrogen (N) requirements of the crop whereas leonardite was applied only one dose (500 kg ha−1) and also combined with three inorganic fertilizer doses (100%, 75%, 50% of recommended inorganic fertilizer dose). According to the results, the highest green herbage yield and nutrient uptake values were observed in LEO-100 whereas N-based treatments significantly decreased yield and nutrient uptake of silage maize. The use of organic materials as a combination with inorganic fertilizer in silage maize cultivation is highly beneficial for sustainable forage production. © 2016 Taylor & Francis Group, LLC.

The effect of soil and foliar Zn fertilization on two varieties of peanut’s (Arachis hypogaea) yield and some yield components were examined in this study. Soil applications of Zn doses were 0, 10, 20 and 40 kg ha-1 whereas 0, 0.5, 1 and 1.5 kg ha-1 Zn were sprayed to leaves. Applications of dose amounts of Zn lead to remarkable increase in yield and 100-seed weight. The effect of Zn treatment found to be statistically important at P<0.01 levels. The highest yield was obtained at COM variety as 6580.0 kg ha-1 with 0.5 kg ha-1 Zn foliar application. The lowest yield was measured at NC-7 variety’s control plot with 3660.0 kg ha-1 in 2007. Foliar application Zn was statistically determined to be important to NC-7 variety peanut’s grain Zn concentration at P<0.05 levels in each year. The economic analyses revealed that 0.5 kg ha-1 foliar application of Zn provided maximum profit with 10271.2 USD Dollars ha-1. © Ankara Üniversitesi Ziraat Fakültesi.

The effects of iron application on some agronomic properties and yield of peanut were determined by measuring basic agronomic properties such as micronutrient contents of soil, leaf and grain samples, oil and protein contents of grain and hundred seed weight. Variety-dose trial was established in 2006 and 2007. Soils were treated with providing 0, 10, 20 and 40 kg ha-1 iron whereas foliar applications were undertaken with 0, 1, 2 and 3 kg ha-1 iron following twenty days of flowering. Iron contents of soil samples were higher than threshold value of 4.5 mg kg-1 which ranged from 7.52 to 9.34 mg kg-1. However, even at this adequate soil Fe, phenological observations revealed iron chlorosis. The average yield in soil treatment at zero dose plot Fe of NC-7 variety was 4417.2 kg ha-1 and increased up to 4848.6 kg ha-1 with application of Fe 10 kg ha-1. Similar results were found for ÇOM variety in soil Fe treatments. The yield of ÇOM variety for zero dose was 4553.3 kg ha-1 and increased to 5273.0 kg ha-1 with Fe 10 kg ha-1 applied plot. The maximum amount with 5317.6 kg ha-1 yield was achieved at 20 kg ha-1. The applications of Fe significantly increased (P<0.01) peanut yield and hundred seed weight. The highest yield of 6030 kg ha-1 in 2007 was obtained with 2 kg ha-1 foliar to ÇOM variety, the lowest yield of 3890 kg ha-1 in 2006, was determined at NC-7 variety which was control. Fe applications had similar positive effects on 100 grain weight. However, oil yield and protein contents of peanuts did not respond to treatments. Economic analysis revealed that the highest income of 10208.0 $ ha-1 was obtained with foliar application of 1 kg ha-1 Fe.

In this study, a new approach for faster determination of quality in hay bale and haylage was aimed. To this end, the relationships between bale densities, dry matter (DM), pH content and penetrometer values in hay bale and haylage were investigated. The mixture of caramba (Lolium multiform cv Caramba) and berseem clover (Trifolium alexandrinum L) was used as forage material. It was harvested by using two different harvesting methods and stored as dry hay and haylage. The penetrometer values were measured at four different points on bales. It was obtained that the pH content decreased with increase in bale density (R2 = 0.86) and with decrease in DM content (R2 = 0.86). The values measured at vertical-middle point gave higher correlation with density and pH contents. © 2016, Eesti Pollumajandusulikool. All rights reserved.

This study estimates the technical efficiency of goat rearing in the province of Isparta in Turkey using Data Envelopment Analysis (DEA). The data used were collected from 92 goat farmers using the stratified sampling method by means of a questionnaire. The technical efficiency of the goat farming varied widely between 0.13 and 1.00. The mean efficiency of 92 goat farms was calculated to be 0.44 and 0.66 for constant and variable returns to scale assumptions, respectively. The greatest slacks were in feedstuff concentrates and labour used. The most significant factors affecting efficiency of goat production were farmer experience, cooperative membership, milk yield per goat, and family and hired labour. Technical efficiency should be improved by providing farmers with well-organised education, an extension program, and research and development programs on goat rearing. © 2016 Sociedade Brasileira de Zootecnia.

The effects of disturbed soil structure on yield and some quality factors such as protein, starch, ash of bread wheat (Triticumsp.) were examined in Cukurova Region. Yield, 1000 kernel weight, plant in m2, protein, starch, ash, oil and gluten contents of grain samples were described in this study. Wheat plants were planted in two different experimental plots. Once, flume (small channel) which is 60 cm deep were cracked in the experimental field. Then, this flume was covered with soil after 30 days. This covered flume soil which have disturbed soil structure were used as control parcels. Other experimental parcels were planted on field which undisturbed soil that have block structur. Wheat plants were planted in two different experimental plots. The effect of disturbed soil structure on yield found to be statistically important at 0.01 levels in each bread wheat varieties. The highest yield was obtained at control parcel which disturbed soil structure of Ceyhan-99 variety as 6100.0 kg ha-1. The yield was 5253.3 kg ha-1 in parcel 1 in which undisturbed soil structure of Adana-99 variety and increased to 5621.6 kg ha-1 in control parcel. Also yield was 5910.0 kg ha-1 in parcel 1 in which undisturbed soil structure of Ceyhan-99 variety and increased to 6100.0 kg ha-1 in control parcel which disturbed soil structure. Similar of disturbed soil structure were also effective on 1000 kernel weight. While 1000 kernel weight of disturbed soil of Ceyhan-99 variety was 36.16 g, the 1000 kernel weight of plot 1 which undisturbed soil structurerealized as 35.76 g. This increasing were statistically important with 0.01 levels on 1000 kernel weight in Ceyhan-99 variety but this effective was statistically insignificant in Adana-99 variety. Also disturbed soil structure was affected on the Plant m-2. The effect of disturbed soil structure on the Plant m-2 was statistically important with 0.01 levels in Adana-99 variety and was statistically important with 0.05 levels in Ceyhan-99.
