Effect of clove diameter and plant growth regulators on growth and yield of balady garlic (allium sativum l. )‎

الملخص EN

The present investigation was laid out during the growing winter seasons of 2015/2016 and 2016/2017 at private farm in Sharnop, Damnhour City, Behera Governorate, to study the effect of clove size and plant growth regulators: 6-Benzylaminopurine (BAP), Naphthalene acetic acid (NAA) on growth and yield of Balady garlic cultivar (Allium sativum L cv).

 Experimental design was split plot in a randomized complete blocks design with three replicates.

The main plot was clove size, and the sub main plot was growth regulators.

The obtained results indicated that vegetative growth characters, bulb yield, its components and bulb characteristics, significantly, affected in case of size of planted bulbs in the both seasons.

Obtained results showed that large size (l) gave the highest means values for all studied traits, in both seasons, followed by medium size (m) and small size (s).

Moreover, It could be concluded that the vegetative growth characters, bulb yield, its components and bulb characteristics significantly affected with the mix treatment (BAP + NAA) which gave the highest mean values for all studied traits over size of planted bulbs in both seasons, followed by BAP and NAA respectively, in both seasons.
