| Popis: | Investigating the effect of urea and nano-nitrogen fertigation and foliar application of nano B and Mo on growth and yield of potato Solanum tuberosum L. [Rivera-A]. The study was conducted in a private farm located in the Al-Taleah area - Babylon governorate. The experiment consisted of (12) treatments consisting of separated fertigation of nano nitrogen (25% N) and urea (46% N), single treatments of leaf spraying of nano Mo (5%), Nano B (9%), nano-binary combinations (Mo+B) and (U+ Nano Mo), (U+Nano B), Nano (N+Mo), Nano (N+B), and tricombination treatments of (U+Mo+B), Nano (N+Mo+B) additional to the control treatment. Randomize Complete Block Design (RCBD) and one way simple experiment with three replicates. Fertilizers were applied at levels of 40 liters h-1 of Nano-N fertilizer (25% N) and 300 kg h-1 urea fertilizer (46% N). They were sprayed early in the morning after (40) days after planting four times. Two weeks is the period between an application and another according to the recommendation of (1) kg h-1 nano-fertilizer of (B) and (500) g h-1 of Mo. Fertilizers were injected and sprayed at (10, 20, 30 and 40)% of the total amount of the fertilizer were applied as the first, second, third and fourth applications, respectively. Some growth traits were tested including the chlorophyll content in the leaves, the total dry vegetative yild, the soft tubers yield, and the biological yield, proteins and ascorbic acid yield compared to the control (spray water only). The results of the Duncan test showed a significant increase in most of the studied traits of nano-tricombination (N+Mo+B) in the fresh tubers yield, dry vegetative yield , the biological yield, starch yield ,the total protein and ascorbic yield (37.53, 1.799, 8.138,4.152 , 481.3and 653.8 meg ha-1) respectively .compare to control (21.58 , 0.890, 4.463 ,2.323 , 366.1 and 215.5 meg ha-1) respectively. |
