  This study was carried out, in Konya Bahri Dagdas International Agricultural Research Institute’s practice and research land. In the study, silage corn varieties growth analyses were made which depending on time. Relative Growth Rates (RGR) were measured all cultivar and times. While these analysis making 5 plants were taken from each plot and measured on these plants. Richards, Logistic, Weibull and Gompertz growth models were used for evaluating. At the models comparing determination coefficient (R2), mean square error were used. As a result this showed that RGR is different from growth features. Weibull function explained RGR better than other models for all of cultivars.

  This study was carried out at Central Anatolian Region ecological conditions. In this study were aimed to compare some statistical growth models for describing seedling growth in early period. Quadratic, square root, exponential and weibull models were used to describe seedling growth. Coefficient of determination and mean square error were used as comparison criteria. As results, when 1000 seeds weight increased, germination rate decreased. Also, when germination rate decreased, leaf length at 25 days and dry weight plant-1 at 25 days decreased, but no of days for 1st tiller to appear increased. Quadratic model explained better than other models for seedling growth.

  The aim of this study was to examine how differences in grain yield, nutritive value, ensilability and harvesting losses of intensively managed some winter cereals (bread wheat, triticale and rye) harvested during the advancing stages of ripening. Three cereal crops (Triticum aestivum L., cv. Konya-2002, Triticale Wittmack. cv. Mikham-2002 and Secale cerale L., cv. Aslim-95) were assessed and Dry Matter concentration (DM), Organic Matter Digestibility (OMD), Crude Protein (CP), Ash Content (AC) and Water Soluble Carbon Hydrate (WSC) were evaluated in five date of harvesting. Dry matter yields changed relatively between harvest dates in three crops. Nutritive value, crude protein and organic matter were relatively small. There were no clear and consistent relationships between harvesting loss and stage of ripeness in current experiment. Loss of wheat yield was relatively high in 2 years. Loss of rye yield showed lower than other. Grain DM concentration increased by average of 9.5 g kg-1 (wheat), 9.2 g kg-1 (rye) and 10.1 g kg-1 (triticale) per day the interval.

  This study was conducted at research and experimental areas of Bahri Dagdas International Agricultural Research Institute. For the experiment, 8 forage plants were used (all plants with a C3 type of photosynthesis and they were grown under some conditions). The experiment was laid out Randomized Complete Block design with four replications. We analyze importance of the growth parameters Relative Growth Rate (RGR), Net Assimilation Rate (NAR), Leaf Area Rate (LAR), Leaf Weight Rate (LWR) and Root Weight Rate (RWR). A large variation in physiological characters between species was observed. Slow-growing species had a constant RGR, NAR and LAR in early stages. Genotypic variation in physiological characters may be an explanation for the observed.

  This study was conducted to determine some yield characters of corn cultivar in Konya province which is located in Middle Anatolian region in 2003 and 2004 years. Eight corn cultivars (Monton, Monzon, Ranchero, Ada, Montel, Progen, 35P12 and TTM 8119) were tested in randomized complete block design with four replicates. Corn yield changed from 10397 kg ha-1 (cv Ranchero) to 12725 kg ha-1 (cv Monton). Corn yield level in Konya was comperatible to other region in Turkey. Therefore, it can be new and large corn production area in coming years.
