Effect of Mineral, Bio and Organic fertilization on Garlic production
Two field experiments were carried out at Mansoura Agriculture Research Station during the two seasons of (2014 2015) and (2015 2016) to study the effect of spraying micro elements in combination with Bio. and organic fertilization on garlic production. The treatments tested are Zn at 60 Ppm Mn at 60 Ppm Fe at 80 Ppm and Zn Mn Fe at 60 60 80 Ppm respectively were sprayed on garlic plants grown in plots treated with Bio fertilizer Nitrobin Phosphorin and combined with organic fertilizer at rate of 10 m Fed 50 of the recommended dose of chemical fertilizer and 100 chemical fertilizer. The results indicated that chemical fertilizers at 100 and 50 (FYM) 50 chemical fertilizers have insignificant effect on plant height, bulbing ratio and bulbing diameter in the two years. While number of leaves and neck diameter were higher in the first season .as affected by 50 (FYM) 50 (chemical fertilizers) Moreover 100 chemical fertilizers give less yield than 50 (FYM) 50 (chemical) in the two years. Bio fertilizers treatments give higher yield than treatments without Bio fertilizers. However, number of leaves was higher in the Bio fertilizers treatments but neck diameter, bulbing diameter and bulbing ratio were not affected in the two yearsAs for spraying with microelements (Zn, Mn, Fe) all parameters were affected significally in the two years. Since microelements give rise to higher values in vegetative growth and total yield (Ton Fed) The results indicated that the triple interactions have no effect on all vegetative growth parameters in the two years but total yield was affected significally in the two years. Finally spraying garlic with (Zn Mn Fe) gives the highest yield under application of (nitrobin phosporin) in combination with 50 FYM 50 chemical fertilizers.
