EFFECT OF SOME ORGANIC FERTILIZER TREATMENTS ON GROWTH AND PRODUCTIVITY OF SOME HUSK TOMATO CULTIVARS

Abstract

Two field experiments were carried out during the two successive growth seasons of 2013 and 2014 in Abu-Ghaleb-Giza governorate (58 Km north Cairo from the desert road). The experiment include 15 treatments which were the simple combination between five levels of organic nitrogen Fertilizer (100% organic, 75% organic + 25% mineral, 50% organic + 50% mineral, 25% organic + 75% mineral and 100% mineral), with three husk tomato cultivars (Toma Verd, Pi1291561 and local one), The obtained results indicated that, the two foreign cultivars resulted have more plant growth measurements (height of plant, leaves and shoots number per plant, fresh and dry weight of whole plant) over the local cultivar. Within the two foreign cultivars Toma Verd, gained the more vigoursity than Pi1291561 cultivar. Also, the highest values of fruits, early, marketable and un-marketable of husk tomato, all of them were correlated to growing Toma Verd cultivar. The physical fruits quality (weight, diameter and size of fruit) recorded their highest values with cultivation foreign cvs. However local cultivar produced the highest values of dry matter, TSS values and Vit. C content. The foreign cultivars resulted the highest values of N, P, K and total acidity valu
