Rashid Obeed
Journal of Plant Nutrition, 2017
The present study was carried out on Kinnow mandarin trees (Citrus reticulata Blanco) to study the effect of urea, zinc (Zn) and boron (B) foliar sprays either alone or in combinations on fruit yield and quality. Trees were grown in alkaline sandy loam soil at Dirab, Riyadh, Saudi Arabia. All trees were sprayed twice: before full bloom (February) and after fruit set (April) during two growing seasons. The obtained results showed a significant increase in tree yield and enhancement in fruit physical characteristics (fruit weight, pulp, juice, volume, length and diameter), as well as fruit chemical characteristics [soluble solids content, acidity, pH, total sugars and ascorbic acid] by all foliar treatments in comparison with the control (water only) in both seasons. Spraying urea in combinations with B and Zn resulted in higher fruit yield and better physico-chemical characteristics as compared with urea only, urea C B or urea C Zn.

Calcareous and alkaline nature of soil hinders smooth up take of micronutrient from soil. Hence, the impact of foliar feeding of micronutrients (Zn, Fe, B, Cu) in different combinations on growth, yield and quality of sweet orange cv. Mosambi in a non-conventional citrus growing area was evaluated. Results revealed that treatment combination of Zn @ 0.5% + Fe @ 0.2% + B @ 0.3% + Cu @ 0.1% (T9) followed by B @ 0.3% + Fe @ 0.2% (T6) and Zn @ 0.5% + B @ 0.3% (T7) was most effective for improving growth of Mosambi plants in terms of shoot length, leaf number, leaf area as well as photosynthetic efficiency of the plant. The yield per plant was also obtained maximum in T9 (14.94 kg). Further, fruit quality attributes in terms of TSS, total sugar, flavonoids, ascorbic acid content as well as antioxidant capacity of the fruit were recorded maximum in T9 with at par result in T6. Therefore, three foliar spray of Zn @ 0.5% + Fe @ 0.2% + B @ 0.3% + Cu @ 0.1% from May-July can be recommended to...
