Abstract
This research was conducted during spring growing season 2011 in unheated plastic house at the Colloge of Agriculture and Forestry , Mosul Universty , to study the effect of different organic fertilizers on vegetative growth , quantity and quality of yield of cucumber hybrid F1 of Grass variety. The organic treatments included : Italpollina , Roct Dove manure , Liqued manure Nitrogreen , Rottend Sheep manure , Humic acid , Sea plant extract Seamino , Chemical fertilizer , and non-fertilizer Control treatment . This experiment was designed as Randomized Complet Block Design ( RCBD ) with tree replication . The results could be summarized as follows : Growth characteristics: Plant length , dry weight per plant and fruit length were as nonsignificantly affected by adding organic fertilizers and chemical fertilizer , whereas the Seaplant extract was significantly superior in fruit diameter and yield and its componed as compared with control and Roct Dove manure treatment . The Italpollina treatment was significantly superior in the total and marketable number fruits per plant as compared with control and Nitrogreen treatments . On the other hand , the same previous treatment was significantly characterized in the total and marketable yield of fruits ( 142.27, 136.46 ton/ ha. ) , with an increase ( 29.67% , 32.81% ) as compared with control treatment respectively ,while increase was nonsignificantly as compared with other treatments in the early fruits yield. Key wards : Organic manure – Cucumber – Plastic houses .
