| Abstract | ||
| During 2013, 2014 and 2015 seasons, Early sweet grapevines received N as 100% mineral N or as 25% to 75% mineral N with 12.5 to 37.5 % plant compost and Minia Azotene biofertilizer. The target was selecting the best ratio between different N sources. Using N as 50 to 75% mineral N besides 12.5 to 25% plant compost and Minia Azotene biofertilizer gave the best results with regard to growth and yield. An obvious reduction on yield was observed with using N as 25% mineral N + 37.5% plant compost + 37.5 % Minia Azotene biofertilizer. For improving yield of Early sweet grapevines, it is suggested to use N as 50% mineral N plus 25% plant compost and 25% Minia Azotene, for promoting physical and chemical characteristics of the berries, it is recommended to use N as 25% mineral N + 37.5 % plant compost + 37.5 % Minia Azotene biofertilizer. | ||
