    EFFECTS OF FOLIAR AND SOIL APPLICATIONS OF DIFFERENT MANGANESE FERTILIZERS ON YIELD AND NET RETURN OF BEAN
    (TAYLOR & FRANCIS INC, 2014) Ozbahce, Aynur; Zengin, Mehmet
    This study was carried out in order to determine the effect of various manganese fertilizers [manganese sulfate (MnSO4.3H(2)O) (MS), 27% manganese (Mn) and manganese ethylenediaminetetraacetic acid (Mn-EDTA) (ME), 12% Mn], their doses (0, 6, 9, 12mg Mn kg(-1) for the soil and 0, 0.2, 0.3, 0.4% for the leaf) on yield and net return of dwarf bean. Field experiments were conducted in the randomized blocks split plot design with four replications under Konya ecological conditions in Turkey. Soil applications were made on bands as a single application at sowing whereas foliar applications (FA) were made at two times. Results of the field experiments showed the highest bean yields were significantly obtained by the fertilizer of ME-FA sprayed (243.80 and 257.74kg da(-1)). For both years, the lowest yields were obtained by the MS-SA applications (166.97 and 180.60kg da(-1)). The maximum net income was US $104.16 da(-1) and US $156.06 da(-1) by years.

    The effects of potassium on the yield and fruit quality components of stick tomato
    (KOREAN SOC HORTICULTURAL SCIENCE, 2013) Colpan, Efnan; Zengin, Mehmet; Ozbahce, Aynur
    This research was performed to determine the effects of potassium applied on soil to increase dose on the yield and yield components of stick tomato (Lycopersicon esculentum L. var. AimAYek) grown in greenhouse conditions in the Antalya Province in 2010. In this experiment, the AimAYek fresh tomato variety commonly grown in the Mediterranean region was tested with applications of 0, 40, 80, 120, and 160 kg K2O/ha. According to the results, the yield was greatest (195.7 Mt center dot ha (-1)) with 120 kg K2O/ha application. The effects of potassium application on tomato yield and yield components were statistically significant (P < 0.01 and P < 0.05). Depending on the application dose, plant stem diameter ranged from 14.22 to 14.99 mm, plant length 173.05 to 181.69 cm, fruit diameter 70.33 to 73.84 mm, fruit number per plant 29.20 to 34.57, fruit weight 160.45 to 185.63 g, penetration resistance 2.45 to 2.99 kg center dot cm (-2), pH 5.10 to 5.20 and sugar content 3.67 to 3.97 A degrees Brix. In addition, the leaf N/K ratio also affected the tomato yield. Significant correlations were found among the macro and micronutrients of the leaf, yield, and yield components.
