QUALITY LOSSES IN TEMPORARY SUNFLOWER SEED STORES AND INFLUANCES OF STORAGE CONDITIONS ON QUALITY LOSSES DURING STORAGE

The aim of storage is to preserve properties of products and their freshness. If suitable storage conditions are not supplied according to product variety, quality and quantity losses increase. Decreasing these losses is possible with providing suitable storage conditions and storage management. In this study were aimed at determining of storage losses in the temporary sunfl ower seed stores and investigating the influences of storage condition on quality losses of sunfl ower during storage

STORING SUNFLOWER SEEDS AND QUALITY LOSSES DURING STORAGE

In this research, sunfl ower storage buildings in the Thrace region were examined. Infl uences of storage condition on product losses were investigated. According to the results of experiments in selected stores, the worst storage conditions and the most quality losses were determined in the concreate store, on the other hand the most suitable conditions and the least losses were determined in model store

SPATIAL DISTRIBUTION IN A DRY ONION FIELD (A PRECISION FARMING APPLICATION IN TURKEY)

Objective of this study is to determine spatial variability in a dry onion fi eld and to produce a management strategy which is based on spatial variability of yield and soil components. The onion fi eld properties were determined and given in maps. Soil samples were taken to determine properties of soil such as pH, salt, humidity, CaCO3, organic matter, total N, Zn, Fe, P2O5, Ca+Mg, K, texture. Longitudinal slope was also measured. Results were used to produce maps. Most percentage of the fi eld soils was determined as clay-loam. Small part of the fi eld was loam. Yield of dry onion decreased by increasing of Organic Matter, Total Nitrogen, Iron, and Zinc in the fi eld according to the related maps. Relationship between yield and phosphorous, CaCO3, Ca+Mg and salt was positive according to the related maps

Usage Possibilities of Diatomite in the Concrete Production for Agricultural Buildings

Construction materials evidently affect economy, strength, durability, safety and expediency of constructions. Selecting locally available material will bring a cost-advantage to structures built in rural parts. Such a case is especially valid for agricultural structures. In present study, effects of a natural pozzolan, diatomite admixture on concrete workability characteristics, setting duration and behavior under axial loading were investigated and possible use of diatomite-blended concrete as a light-weight construction material in agricultural structures was evaluated. This research was carried out in Tokat/Turkey in 2012. Concrete samples were prepared by using different admixture ratios of diatomite as a light-weight aggregate with standard sand and crashed sand aggregates. Water/cement ratios of mixtures were determined by taking a constant slump value into consideration. Unit weight, compressive strength and water absorption test were carried out over the samples. According to the results, unit weight, compressive strengths and water absorption in 150, 200 and 250 doses changed with increasing diatomite contents, respectively, from 1470 kg/m3 to 2210 kg/m3, from 20.45 MPa to 1.14 MPa, from 6.04% to 23.85%. Results revealed significant cost-savings by using diatomite aggregate to produce light-weight concrete blocks to be used in agricultural structures. It was also concluded that such blocks might provide significant insulative advantages for heat-balance of livestock barns.

Determination of Spatial Variability in Olive Production: Part I - Soil

The aim of this research is to determine soil spatial variability and strategies of fertilization. This research was carried out in an olive orchard which has 84 trees in Turkey. Soil analyses were realized by using samples which were taken from grids. Soil of the olive orchard was suitable for olive growing due to physical and chemical analysis except organic matter, (partially P), Mn, and Zn. Due to the results of analyses; N, P, Mn and Zn will be required for the next year olive production. The fertilization strategies must be included these applications. It should not be forgotten that the soils which are adequate in potassium and partially phosphorus, may become poor in P and K as like organic material in the length of time

The Effects of 15 or 30 s SIT in Normobaric Hypoxia on Aerobic, Anaerobic Performance and Critical Power

Sprint interval training (SIT) is a concept that has been shown to enhance aerobic-anaerobic training adaptations and induce larger effects in hypoxia. The purpose of this study was to examine the effects of 4 weeks of SIT with 15 or 30 s in hypoxia on aerobic, anaerobic performance and critical power (CP). A total of 32 male team players were divided into four groups: SIT with 15 s at FiO2 : 0.209 (15 N); FiO2 : 0.135 (15 H); SIT with 30 s at FiO2 : 0.209 (30 N); and FiO2 : 0.135 (30 H). VO2max did not significantly increase, however time-to-exhaustion (TTE) was found to be significantly longer in the post test compared to pre test (p = 0.001) with no difference between groups (p = 0.86). Mean power (MPw.kg) after repeated wingate tests was significantly higher compared to pre training in all groups (p = 0.001) with no difference between groups (p = 0.66). Similarly, CP was increased in all groups with 4 weeks of SIT (p = 0.001) with no difference between groups (p = 0.82). This study showed that 4 weeks of SIT with 15 and 30 s sprint bouts in normoxia or hypoxia did not increased VO2max in trained athletes. However, anerobic performance and CP can be increased with 4 weeks of SIT both in normoxia or hypoxia with 15 or 30 s of sprint durations
