Potassium, Poultry Waste and Licorice Extract Effect on Growth , Yield and Substance of Garlic ( Allium atroviolaceum L. )

Abstract

A factorial experiment was conducted for the 2012-2013 on garlic ( Allium atroviolaceum L. ) at agricultural Station Tikrit University According ( RCBD ) . the experiment included twelve treatment produced by interaction between the organic fertilization with three levels (zero , 10 m 3 / acres, 20 m3 / acre ) and potassium fertilization two levels (zero , 40 kg / acre ) and spraying extract of licorice two levels (zero, 10 g / l) with three replicates , to study the effect of potassium and poultry waste and licorice extract to the growth and yield some effective compounds : The study showed1- The results showed that organic fertilization has given a significant increase in plant height ( cm ), leaf area cm2 , head diameter (mm), total yield ( 87.08 cm, 99.2 cm2 , 62.53 mm, 21.2 T / ha ), while the potassium fertilization give significant increase in , head diameter ( 58.25 mm) .2- The interaction between organic fertilizer, potassium fertilization had significant increasing in plant height, area leaf, total yield) ( 88.18 cm, 101.6 cm2 , 21.95 t / ha ..3- The tri interaction between organic fertilizer, potassium and licorce extract had significant increasing to plant height , leaf area , total yield ( 88.7 cm , 104.4 cm2 , 22.95 T/H ) while the inereaction between licorice extract and potassium had superiority in leaf area , total yield ( 116 cm2 , 23.73 t / ha ) .4- The treatment F3K2G1 had clear effect: S-allyl cystine and Y-glutomyl cystine which was more superiority to other treatment, it gave highest concentration reached ( 59.69 micrograms . ML ) ( 65,534 micrograms . ML ) compared with control . the treatment F3K2G2 highest concentration of (agoene) reached to ( 103.48 micrograms . ML ) compared with control , while the treatment F2K2G1 gave highest concentration of Di - allyl tri sulfide reached to 68.88 micrograms . Ml ) compared with F1K2G2 treatment .
