    COMPARISON OF SOME MATHMATICAL GROWTH MODELS FOR ESTIMATING OF PYHSIOLOGICAL GROWTH CHARACTERS OF ALFALFA (MEDICAGO SATIVA L.)
    (Society for Innovative Agriculture, University of Agriculture, 2021) Karadavut, U.; Palta, C.
    Clover plant is a perennial plant and can be harvested 3-6 times depending on growing area. Because of this feature, it is very less used in growth studies. This study was carried out in Yozgat ecological conditions where, 4 harvesting can be taken. Bilensoy (registered variant in Turkey) alfalfa variety growth analysis was made depending on time for each cut. At growth analysis, leaf area index, leaf area ratio, leaf growth ratio, plant growth ratio, relative growth ratio and net assimilation ratios were measured. Growth analysis was made on 5 plants taken from each plot. Measurements were taken at 6 different times of each cut. Richards, Logistic, Weibull, MMF, Gompertz, Exponential, Power, Gaussian, and Rational growth models were used for evaluating. Determination coefficient (R2) and Mean square error were used as comparison criteria. As a result, Weibull and Richards growth models explained very well plants growth of alfalfa. Leaf area index 96.3; Leaf area ratio 96.1; leaf growth rate 9.4; In the Weibull model with the coefficient of determination, the net assimilation ratio of 95.9 and the plant growth rate of 96.8 have the highest explanation value in the Weibull model. © 2021 Society for Innovative Agriculture, University of Agriculture.

    ESTİMATİON OF GENETİC AND ENVİRONMENTAL PARAMETERS AFFECTİNG PRODUCTİVİTY İN MORKARAMAN SHEEP AND ECONOMİC EVALUATİON OF PARAMETERS
    (Society for Innovative Agriculture, University of Agriculture, 2021) Karadavut, U.; Bahadir, B.; Karadavut, V.; Simsek, G.; Inci, H.
    This study was carried out to protect the continuity of productivity in morkaraman sheep raised in Turkey and determine their economic importance. Morkaraman sheep are concentrated in the Eastern Regions of the country. The province of Bingöl, where the study was conducted, is located in this region and has an important morkaraman population. The study was carried out between 2008-2018. Sixty-eight morkaraman sheep were used during the study period out of 317 lambing lambs. In the study, the total number of lambs born per sheep (TNLBS), the number of weaned lambs (NWL), the weights of the lambs weaned per sheep (WLWS) and the total weight of the lambs weaned in the first period (TWLWFP) were determined. In addition, Additive genetic variance, Error variance, Phenotypic variance, Heritability and Ratio of error variation were determined for these variables. As a result, the correlation between the examined variables was significant and positive, except for the relationship between TNLBS and TWLWFP. The relationship between these two variables was significant but negative. Significant changes were also observed in terms of genetic parameters. It was concluded that the economic aspects of the examined variables should not be ignored in terms of sustainability. © 2021 Society for Innovative Agriculture, University of Agriculture.

    A SİMULATİON STUDY TO DETERMİNE THE RESPONSE OF MORKARAMAN SHEEP RAİSED İN CENTRAL AND EASTERN ANATOLİAN TO CHANGİNG CLİMATE CONDİTİONS
    (Society for Innovative Agriculture, University of Agriculture, 2021) Karadavut, U.; Bahadir, B.; Karadavut, V.; Simsek, G.
    Climate change has begun to affect the whole world seriously. If necessary and sufficient measures are not taken, it seems possible that much bigger disasters will occur in the future. The agricultural sector, which forms the basis of food production, is affected the most and rapidly by this change. Significant decreases have been observed in plant and animal production. Our primary purpose is to determine the reproductive potential of animals and the amount of resistance to climate change and evaluate the economic situation. The study was carried out within ten years, covering 2009-2019. In this study, morkaraman sheep bred in the province of Kırşehir in the Central Anatolian Region and the province of Bingöl in the Eastern Anatolia Region is considered material in Turkey. In order to obtain the data used, a total of 296 sheep, 145 sheep in the Eastern Anatolia Region and 151 sheep in the Central Anatolia Region, were evaluated. The simulation study was carried out using the polygenic model. The variables examined are as follows; Lactation time (days), Average daily milk yield (ml), Daily amount of feed consumed for 1 kg live weight (kg), Yield (%), Incidence of Mastitis, Daily oil yield (g/day), Daily protein yield (g/day), Fertility (%), Fertility time (productivity) (Days), Change in milk yield for each degree above 22 °C and Protein change for each degree above 22 °C (g/°C/day). As a result, in a one-degree increase in temperature, the highest negative effect is seen in the average daily milk yield and lactation period. Fertility and the amount of feed consumed per kg of weight had the lowest value. The preliminary work to be done with the work is that the selection of animals that are resistant/tolerant to climate change should be made. © 2021 Society for Innovative Agriculture, University of Agriculture.
