| Abstract |
Two field experiments were carried out under plastic greenhouse at the Vegetable Farm of Faculty of Agriculture, Benha University during the two winter seasons of 2019/2020, and 2020/2021 to study the effect of foliar application with some growth stimulants, i.e., amino acids at 0.5 and 1 g/L, zinc at 1 and 2 g/L, calcium boron at 2 and 4 ml/L, salicylic acid at 500 and 1000 ppm, chitosan at 2 and 4 g/L and lithovit at 1 and 2 g/L in addition to the control treatment (spray with tap water) on vegetative growth, chemical constituents of plant foliage, productivity, fruit quality and storability of cucumber fruits. The experiment was designed as complete randomized block with 3 replicates. Obtained results show that treatment the plants with amino acids at 1g/L exhibited the highest values for all measured growth aspects, photosynthetic pigments and macronutrient content N, P, K and total carbohydrates. Moreover, the highest number of fruits/plant, fruit yield/plant and total fruit yield/m2 were obtained as a result of spraying cucumber plants with caboron at 4 ml/L every 10 days intervals starting 21 days form transplanting with best physical and chemical quality. In addition, preharvest foliar application of chitosan at 4g/L can be recommended for preservation for physical and chemical quality induces of cucumber fruits (the lowest weight loss, decay percentage) during cold storage 7°C up to 21 days. |
