Determination of suitable varieties for second product peanut growing in Mardin province

Due to different reasons, only corn plant is preferred for second crop planting in Mardin province. However, there are some researches on low-cost plant cultivation, which can be an alternative to the second crop after the main crop, because the corn plant both exploits the soil and needs a high amount of water and increases the cost of electricity due to the irrigation done with pressurized systems. The peanut plant is one of them. Since good results were obtained in the second crop peanut cultivation carried out under farmer conditions in Mardin in 2020, it has been the subject of this research. In this sense, the adaptation of 10 peanut varieties as the second product after wheat under pandemic conditions in 2021 in Mardin province was investigated. Trials were carried out in Random Blocks Trial Design with three replications. In the study, characteristics such as plant height, number of main branches and fruit per plant, internal ratio, fruit yield per plant, seed yield per plant, 100 seed weight, fruit yield and grain yield were investigated. According to the results of analysis of variance, significant differences were determined between cultivars in terms of plant height and number of main branches by 0.5%, and between cultivars by 0.1% in terms of other characteristics. According to the results of variance analysis; plant height; 62.1-53.1 cm, number of main branches; 4.53-5.20 units/plant, pods per plant; 27.3-42.5, grain rate 37.0-47.1%, grain yield per plant (bean); 71.7-120 g, yield per plant (seeds); 25.1-51.3 g, weight of 100 seeds; 68.1-103.4 g, grain yield (pods); 2143-5079 kg/ha, grain yield (seed); 937-2207 kg/ha. According to these results; in terms of grain yield, fruit yield, fruit yield per plant and 100 grain weight; NC-7 and Masal cultivars had high values for Gazipaşa cultivar in terms of seed ratio. As a result, NC-7 and Masal varieties are recommended for second crop cultivation in Mardin conditions.
