Neval Topcu Altıncı | Rüstem Cangi | Deniz Üstün
Plants are constantly exposed to adverse conditions in their environment, which may occur in different ways, limiting their growth. These negative states that affect and / or prevent growth, development and metabolism in plants are called stress. Salicylic acid (SA) is a hormone-like substance commonly found in plants and is now accepted to play an important role in regulating plant growth and development. Salicylic acid also increases the tolerance of plants under abiotic stress conditions such as salinity, high and low temperature, water, heavy metal, frost and drought stress. This study is one of the important white wine grape varieties belonging to Turkey's Narince grape varieties growing in Tokat made widely used. Salicylic acid (SA) was applied to the plants in 4 different doses (0, 0.5, 1.0, 1.5 µmol l-1) before high temperature stress to be applied and they were exposed to high temperature for 12 hours at 40°C in the growth chamber. At the end of the 21 days after the stress application, shoot length (cm), fresh -dry shoot and root weights (g) were taken in order to follow the plant growth from the plants. Proportional water content (%), Ion flow (%) to reveal the effect of salicylic acid and the cell membrane damage rate (%) was calculated.

Deniz Köçeroğlu | Tahir Yücel | Emre Bakkalbaşı | İsa Cavidoğlu
Türkiye kuruyemiş üretimi ve tüketimi açısından dünyanın önde gelen ülkeleri arasında yer almakta ve birçok ürün kuruyemiş olarak kullanılmaktadır. Bu ürünlerden biri de karpuz çekirdeğidir. Bu çalışmada Mardin, Diyarbakır ve Batman illerinden temin edilen ve çerezlik olarak tüketilen karpuz çekirdeklerinin bazı kimyasal bileşenleri belirlenmiştir. Ayrıca Batman ilinden temin edilen karpuz çekirdekleri 140, 160 ve 180°C’de 60 dakika boyunca kavrulmuş ve kavurma işleminin karpuz çekirdeği yağının oksidatif stabilitesi üzerine etkileri araştırılmıştır. Karpuz çekirdeklerinin kuru madde, kül, yağ, protein, toplam tokoferol ve toplam fenolik madde miktarlarının sırasıyla %95,39-95,58, %3,10-3,38, %51,65-52,75, %32,76-34,87, 360,12-393,16 mg/kg ve 427,75-478,80 mg GAE/kg yağsız kısım aralıklarında değiştiği tespit edilmiştir. Karpuz tohumlarının yağ asidi bileşimi incelendiğinde ise elzem yağ asidi olan linoleik asit açısından (%60,74) önemli bir kaynak olduğu ve oleik asidi de (%20,48) yüksek miktarda içerdiği belirlenmiştir. Yapılan çalışmada karpuz çekirdeklerinin yağ asidi bileşiminin kavurma işleminden etkilenmediği ve peroksit sayısının ise 1,57- 3,0 meq O2/kg yağ olarak dar bir aralıkta değiştiği gözlenmiştir. Buna karşın kavurma sıcaklığının, örneklerin peroksit değeri üzerindeki etkisi istatistik açıdan önemli bulunmuştur. K232 değerleri örneklerde kavurma süresince 2,54 ile 4,01 arasında değişirken, K268 değerleri ise 4,99 ile 5,04 arasında değişmiştir. 180°C’de kavrulmuş örneklerin K232 ve K268 değerleri 140 ve 160°C’de kavrulmuş olanlardan istatistiksel olarak farklı bulunmuştur. Çalışma sonucunda karpuz çekirdeklerinin elzem yağ asidi olan linoleik asidi önemli miktarlarda içerdiği ve kavurma işleminin yağ oksidasyon parametrelerinde düşük düzeylerde değişimlere neden olduğu tespit edilmiştir.

Common bean (Phaseolus vulgaris L.) production is constrained majorly by drought and low soil fertility in Kenya. These limitations have never been adequately approached due to financial challenges and lack of better technology. A study was carried out in Kirinyaga and Embu Counties to evaluate the effects of tillage method and residual fertilizers on yield performance of dry bean. Dry bean was grown in the short rains season on plots preceded by fertilized maize (Zea mays L.) grown in the long rains season. The trials were laid out in a randomized complete block design with a split-plot arrangement. The tillage methods, NT+CR and CT-CR, where NT: No-tillage, CT: Conventional tillage, and CR: Crop residue, were assigned the main plot and residual fertilizers (NK, NP, PK, NPK, and NPK+CaMgZnBS) the subplots. The results showed that there was 35% and 46% more water retention under NT+CR than under CT-CR system in Embu and Kirinyaga sites, respectively. NT+CR produced higher biomass, more number of pods per plant, number of seeds per pod, and 1000-seed weight. Plots with residual NPK+ZnBMgCaS yielded higher biomass at 60 DAE, number of seeds per pod, 1000-seed weight and grain yield than plots with other treatments. The residual NPK+ZnBMgCaS and NPK treatments out yielded PK treatment by 600 kg ha-1 and 370 kg ha-1 (Embu) and by 710 kg ha-1 and 330 kg ha-1 (Kirinyaga), respectively. Based on these results, cultivation of dry bean on residual fertilizer nutrients solely or in combination with no-till and crop residue retention after maize harvest has the potential to improve the yields and food security among farmers in the region.

Güngör Karakas
The purpose of agricultural policies is to meet the food demand that the society needs. While supports and incentives for agricultural production increase production, they can have negative consequences on climate change. In parallel with the increase in agricultural production and climate change in the world, there has been a serious increase in both food waste and obese numbers recently. While the overproduction effort of agricultural products creates pressure on the environment, it causes obesity and overweight problems. According to the World Health Organization (WHO), Turkey is at the forefront among the countries where there are obese and overweight people. In the 11th Development Plan in Turkey, in 2018 the prevalence of obesity is 30% (for ages 15 and over) in 2023 is targeted to be reduced to 29.1. The aim of this research is to draw attention to the relationship between climate change and obesity and to address the issue within the framework of the 11th Development Plan. Obesity issues for Turkey; since it is important in terms of food security, climate change and agricultural policies, it is necessary to develop political guidance and protection measures in terms of health, economy, education, environment and national security.

Effect of Different Forms and Levels of Urea Fertilizer on Rice (Oryza sativa L) and Mineral Nitrogen Status in Soil Full text
2020
MD. Belal Hossain | Rakhi Rani Sarker
Field experiment was conducted to determine the effect of prilled urea (PU) and urea super granule (USG) with their different nitrogen levels (N1 : 70, N2 : 100 and N3 : 130% of the recommended dose) on rice and NH4+-N/NO3- -N in post-harvest soil. Experiment was laid out in a randomized completely block design with three replications at Bangladesh Institute of Nuclear Agriculture (BINA) Farm, Mymensingh, Bangladesh during 2015-16. Higher yield attributing characters (plant height, effective tiller panicle-1, panicle length were achieved from USG × N2 treatment. USG, N2 (100% N) and USG × N2 produced the highest grain (3.60, 3.64, 3.78 t ha-1) and straw yield (3.55, 3.45, 3.70 t ha-1) respectively. Though USG × N3 treatment produced the highest effective tiller, panicle length and unfilled grain but USG × N2 treatment produced maximum grain yield of rice due to higher filled grain. In respect of mineral nitrogen, NH4+-N was decreased with the increase in soil depth but opposite result was found in NO3- -N in soil. Deep placement of USG fertilizer released NH4+-N slowly and steadily compared to prilled urea in soil. As a result, one time fertilizer application of USG is better than three times broadcast application of PU in terms of crop yield, nitrogen status in different depth of soil and labour cost. Future research needs to develop the effective USG fertilizer applicator for deep placement in soil during crop production.
