The study was carried out in the greenhouse at Al-Tuwaitha Experimental Station / Baghdad, Agricultural Research Directorate, during December 2011 to February 2012 using Riviera cv. potato. Treatments included effect of interaction between nutrient solution and foliar spray on potato plants grown hydroponically. Completely Randomized Design (CRD) was adapted. The results showed superiority of all fertilizer treatments under study comparing with the control treatment F0. Treatment F7 (Nutrient Solution + Agroleaf) significantly increased the number of stems, height of plant, leaf area and dry weight of shoots (4.00, 66.33 cm, 95.40Dcm2, 31.22 g respectively), in comparison with the control. Moreover this treatment showed significant increase in the percentage of N, P and K in the leaves (1.91, 0.99, 3.68%, respectively). compared with the control treatment which gave 0.13, 0.00, 1.07% respectively. However F5 treatment showed the highest percentage in N(1.06%) compared with the F0 treatment (0.07%.) in the tubers.

    Early-season nitrogen (N) is necessary for optimal potato vegetative growth and creating an optimal growing condition for high yields; however, on sandy soils it also increases the risk of losing fertilizer N through leaching. This 3-year field experiment evaluated whether a smaller amount of N...

    Meristem dormancy in perennial plants is a developmental process that results in repression of metabolism and growth. The cessation of dormancy results in rapid growth and should be associated with the production of nascent transcripts that encode for gene products controlling for cell division...
