Effect of Chicken Manure Levels, Biofertilizers and Some Foliar Application Treatments on Garlic 1. Plant Growth and Leaf Pigments

Abstract

Two field experiments were carried out during the two successive winter seasons of 2008/2009 and 2009/2010 at El-Gemmeiza Agricultural Research Station, Gharbeya Governorate, to evaluate the effect of chicken manure levels, biofertilizers, some foliar application treatments and their interactions on plant growth and leaf pigments of garlic (Allium sativum L.) Sids 40 clone. The obtained results showed that the highest values of plant height, number of leaves/ plant, leaf area , fresh and dry weights/plant, neck and bulb diameters at 105 and 135 days after planting in both seasons and dry weight of bulb at 135 days after planting, chlorophyll a, b and total (a+b) as well as carotenoides were recorded with the highest nitrogen rate (120 kg N/fed.) in the form of chicken manure at 4.137 ton/fed. or mineral N (control). Inoculation of garlic cloves with biofertilizers caused a high significant effect on all plant growth characters and leaf pigments as compared to uninoculated plants. Spraying garlic plants with yeast extract significantly increased plant height, number of leaves/ plant, fresh and dry weights/ plant, neck and bulb diameter as well as dry weight of bulb at 135 days after planting, chlorophyll a, b and total (a+b) as well as carotenoides in both season followed with spraying seaweed extract treatment. The best results of vegetative parameters were obtained with application of nitrogen fertilizer at 120 kg N/fed. of chicken manure at rate of 4.137 ton/fed. or mineral nitrogen with biofertilizers and foliar application of yeast extract. Therefore, this treatment could be recommended for improving garlic vegetative growth parameters under similar conditions to this study.

Effect of some Bio-stimulants on Growth, Yield and Bulb Quality of Garlic Grown in Newly Reclaimed Soil, New Valley-Egypt

“…The obtained results are in accordance with those reported by Tartoura and El-Saei (2006), Abd El-Mageed et al (2009), El-Morsy et al (2011 and Dawa et al (2012) on garlic.…”

“…It was reported that the yeast extract had a stimulatory effects on several process in plant such as cell division, chlorophyll formation, synthesis of protein and nucleic acid beside its content of protective agents, i.e., sugars, amino acids, protein and several vitamins (Wanas, 2006). Treated garlic plants with yeast extract as foliar spray had significant effect on vegetative growth, yield and its components as well as bulb quality (El-Morsy et al, 2011;Dawa et al, 2012;Mansour, 2012;Abou El-Khair and Khalil, 2014;Shalaby andEl-Ramady, 2014 andAhmed, 2015) on garlic plants and (Fawzy et al, 2012 andShafeek et al, 2015) on onion plants. Other effects of yeast on plant growth and yield of some vegetable crops El-Greadly, 2007 andFawzy et al, 2010) on beans, (El-Tohamy et al, 2008) on eggplant, (Fathy et al, 2000) on tomato, (El-Desuki and El-Greadly, 2006) on pea, (Ghoname et al, 2010) on sweet pepper, (Ahmed et al, 2011 andAhmed et al, 2013) on potato and Shehata et al (2012) on cucumber.…”
