One of the most important factors that increase soil fertility is the amount of soil organic matter. One of the ways to increase soil organic matter is the addition of organic fertilizers. Yemsoy soybean cultivar was used in the study, and pot study was carried out in 3 replications according to the randomized blocks experimental design. In the study, three different fertilizer doses (EC 0- 0.5- 1), three different grape pomace compost (0- 20-40 %) were applied to the peat perlite mixture, and mycorrhiza and bacteria inoculation to these environments. At the end of a 60-day growing period, the plants were harvested from the top of the pot, and measurements were made. In the study, there was an increase in the above-ground fresh and dry weights, root fresh, and root dry weights of soybean plants grown with increasing fertilizer rates. The addition of compost to the growing medium, the addition of mycorrhiza, and bacteria caused different results in the investigated properties. The increase in compost and plant nutrition doses was effective in increasing plant growth.

Toprak verimliliğini artıran en önemli faktörlerin başında toprak organik madde miktarı gelmektedir. Toprak organik maddesini artırmanın yollarının başında organik gübrelerin ilavesi gelmektedir. Çalışmada Yemsoy soya fasülyesi çeşidi kullanılmıştır, tesadüf blokları deneme desenine göre 3 tekerrürlü olarak saksı çalışması yürütülmüştür. Çalışmada torf perlit karışımına üç farklı gübre dozu (EC 0-0,5–1), üç farklı üzüm posası kompostu (%0–20–40) ve bu ortamlara mikoriza ve bakteri aşılaması şeklinde gerçekleştirilmiştir. Bitkiler 60 günlük bir yetiştirme süresi sonunda saksı üstü kısmından hasat edilerek ölçümler yapılmıştır. Çalışmada artan gübre oranlarında yetiştirilen soya bitkisinin toprak üstü yaş ve kuru ağırlıkları, kök yaş ve kök kuru ağırlıklarında artışlar yaşanmıştır. Yetiştirme ortamına kompost katılması, mikoriza ve bakteri katılması incelenen özelliklerde farklı sonuçlar ortaya çıkmasına sebep olmuştur. Kompost ve bitki besleme dozlarının artışı bitki gelişimini artırmada etkili olmuştur.

In this study, it was aimed to increase grain yield and grain zinc content by foliar application of zinc in different soybean varieties. In this study, umut-2002, altınay and cinsoy cultivars were used as material and foliar zinc application (0-60 kg ha-1) was applied to these cultivars. In the study, plant height, first pod height, leaf chlorophyll content, number of pods per plant, number of pods per pod, 100-seed weight, grain yield, grain protein content and grain zinc ratio were measured. This increase was also observed in grain protein content and grain zinc content. Among the varieties, the highest grain yield was obtained from the Umut-2002 variety, while the highest protein content was measured from the Altıny variety.

In this study, input oriented efficiency analysis of soybean growing in Adana province was performed. Data were collected from 84 farmers with face to face survey method by using stratified sampling method. In the analysis of data economic analysis of soybean production was performed and after input use efficiency in soybean production was analysed by Data Envelopment Analysis. In addition, the distribution of expenditure and income components is examined according to the status of the enterprises being efficiency. According to the analysis results, the average soybean area width in Adana province is 121.78 and average soybean yield 430 kg/da calculated as. According to DEA with input oriented, technical efficiency was calculated as 0.881, pure technical efficiency as 0.950 and scale efficiency as 0.920.
