Bazı Organik Besin Kaynaklarının Cin Mısırın (Zea mays L. everta) Tane Verimine Etkisi

This study was carried out to determine effect of sixteen different organic nutrition sources to grain yield of popcorn (Zea mays L. everta) in Cermik district of Diyarbakir province of Turkey between 2010 and 2011 years. The research was established according to Randomized Complete Block Designs (RCBD) with 3 replicates and Ant-Cin 98 popcorn variety was used as crop material in the study. Organic nutrition sources were torf, compost, cattle manure, chicken manure, horse manure, sheep manure, pigeon manure, vermicompost, seaweed + cattle manure, compost + humic acid, cattle manure + humic acid, chicken manure + humic acid, horse manure + humic acid, sheep manure + humic acid and torf + humic acid except conventional. In both years, applications affected significantly popcorn yield (P≤0.01). According to average of two years, the highest popcorn grain yields were found at seaweed + cattle manure, horse manure + humic acid and sheep manure + humic acid applications. Grain yields of these applications were 526.54 kg da-1, 516.85 kg da-1 and 497.07 kg da-1, respectively. Seaweed + cattle manure, horse manure + humic acid, sheep manure + humic acid and pigeon manure of applications were caused a 9.47%, 7.45%, 3.34%, 0.52% increase in yield compared with the conventional application, respectively. Also economic analysis was performed in this study. The greatest net profits were obtained from horse manure + humic acid application (2280.64 TL da-1) in 2010 while horse manure (2545.82 TL da-1) application in 2011. According to yield, quality and economic net profit; horse manure, chicken manure, compost, cattle manure, sheep manure and humic acid applications can be used in organic popcorn farming.
