Effect of different fertilizer sources (chemical and biological) on yield and yield components and some agronomic traits of two varieties of garlic (Allium sativum)

In order to study the Effect of different fertilizer sources (Chemical and biological) on yield and yield components and some agronomic traits of two varieties of garlic (Allium sativum) an experiment as spilt plot in randomized complete block design with three replications has been conducted in the Agriculture and Natural Resources Research Station of Zehak in 2014. Different fertilizer sources was in 7 levels include (Nitroxin, nitrokara, fertilizer phosphate 2, chemical fertilizer NPK, chemical fertilizer+ nitroxin, chemical fertilizer+ nitrokara, chemical fertilizer+ fertilizer phosphate 2) as the main factor and two varieties of garlic include hamedani and chines as the subordinate factor. The result showed that different fertilizer sources was significant effect on plant height, steam diameter, garlic yield, garlic diameter and number of clove. So that, the result showed that varieties was significant effect on plant height, garlic yield, garlic weight, number of clove, clove diameter and clove weight. Such that, means comparison of fertilizer effect showed that highest plant height (50.16 cm) and garlic yield (8350.7 kg.ha-1) was obtained from chemical fertilizer+ nitroxin (F5) treatment and in other hand lowest plant height (30.50 cm) and garlic yield (6636 kg.ha-1) was obtained from chemical fertilizer NPK (F4) treatment. In addition, means comparison of varieties showed that highest plant height (43.52 cm) and garlic yield (8342.3 kg.ha-1) was obtained from var. hamedani (V2) treatment and in other hand lowest plant height (39.90 cm) and garlic yield (6949.4 kg.ha-1) was obtained from var. chines (V1) treatment, respectively.
