| Filed experiments were conducted during 2014 and 2015 seasons in a private orchard in El-Nianaia, Minufiya governorate, Egypt to study the effect of foliar spray with in aqueous solutions of biofertilizer (azolla and blue green algae extract at the rate of 1 L/20L water for each, commercial liquid organic fertilizer of humic acid (H.A.) at the rate of 200 cm3/20 L water and their combinations on vegetative growth, yield and fruit quality. Trees of apricot (Prunus armeniaca L.) cv. Canino at 10-years-old trees grown in clay loam soil at 3 x 4 m apart under flood irrigation system. The obtained results indicated that most of the used treatments improved the means of blade width and length, leaf surface area, weight and total chlorophyll. Also, fruit set %, yield/tree, the fruit dimensions, volume and weight, as well as stone weight and flesh weight % take various significance levels as compared to control in both seasons. However, the highest means in most of previous treatments were attained in both seasons with their combinations of Azolla, blue green algae extract and humic acid. The changes in the percent of weight loss, TSS, acidity and total sugars in juice were improved during the period of cold storage. The firmness of the fruits was descendingly decreased as the advancing of period of cold storage, but the opposite trends was right regarding TSS and weight loss %, which were progressively increased with prolonging the period of cold storage. Whereas acidity % was declined by all the applied treatments to reach the minimal values by either blue green algae treatments or when mixed with either Azolla or humic acid. In addition, leaf content of N, P, K and Mg as well as fruit content of N, P, K, Ca, Mg, Na, Fe, Zn and Cu were also increased. Hence, it can be recommended to spray the foliage of 10-years-old trees "Canino" apricot cv. grown under clay loamy soil with the aqueous extract Azolla + Blue green algae + humic acid, to increase both yield, fruit quality parameters and fruit storability period. | ||||
