EFFECT OF SEA WEED AND AMINO ACID ON FRUITING OF SOME GRAPEVINE CULTIVARS
These investigations were carried out during 2014 & 2015 growing seasons on Arra 15 and Arra 20 grapevines grown in sandy soil under drip irrigation in a private vineyard located at Tabark Farm, Ismailia Governorate, Egypt. The experiments were designed to investigate to evaluate the effects of foliar spray with different of treatments amino acid and sea weed extract levels on yield, quality and chemical constituent of Arra 15 and Arra 20 vine cultivars. Foliar spray of treatments were sprayed four times at growth start after flowering (first. of April), just after berry setting (mid. of April) then at one-month later (mid. of May) and at two weeks (last of May). The obtained results showed that Arra 15 CV vines displayed the higher effect in most cases of their tested attributes compared with Arra 20 CV vines. On the contrary, Arra 20 CV vines was high significantly cluster width (cm), cluster round (cm), yield per vine or per feddan, fruit physical and chemical characteristics compared with Arra 15 CV vines. Sprays Arra 15 CV and Arra 20 CV vines of seaweed and amino acids had an obvious promotion on cluster characteristics, as well as increased yield per vine or per feddan and improve of fruit qualitycompared with control treatment. Conclusively, from result of this research, it is recommend spraying of sea weed with amino acid four times at growth start after flowering (first. of April), just after berry setting (mid. of April), then, at one month later (mid. of May) and at two weeks (last of May) improved the cluster characteristics s and increasing fruit yield as well as enhanced fruit quality of grapevine.
