Evaluation of Integrated Fertilizers Management on Growth and Seed Production of Bottle Gourd (Lagenaria siceraria L.) under Sohag Governorate Condition

This field experiment was carried out at Shandweel Research Station, Sohag Governorate, Agricultural Research Center, Egypt, during the two summer seasons of 2020 and 2021 to evaluate the influence of Integrated Nutrient Management (INM) application of organic, inorganic and bio- fertilizer on vegetative growth, flowering, fruit yield, dry seed yield and its components as well as seed quality of bottle gourd. All studied treatments were arranged in a randomized complete block design with three replicates. The results mentioned that the combinations of adding [75% RDF (NPK) + Azospirllum +10m3 FYM/fed] was the best treatment and gave the highest values of vegetative growth and flowering, fruit yield, dry seed yield and its components as well as seed quality and followed by adding [50% RDF (NPK) + Azospirllum +10m3 FYM/fed]. However, the lowest mean values of vegetative growth and flowering, fruit yield, dry seed yield and its components as well as seed quality were obtained by adding (Azospirllum/fed).
