Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 58
Abstract
An experiment was conducted to evaluate the effect of nitrogen and micronutrients on growth and yield of ber (Ziziphus mauritiana L.) cv. Gola under malwa plateau of Madhya Pradesh at the Instructional cum research fruit orchard, Department of Fruit Science, College of Horticulture, Mandsaur during 2010-11 on well established six years old orchard of ber planted at 6.0 m X 6.0 m.. The experiment was laid out in Randomized Block Design (RBD) with three replications. The experiment comprised eleven treatments including control (T1), Urea 1.5 %, (T2), Urea 1.5% + ZnSo4 0.25% (T3), Urea 1.5%+ ZnSO4 0.50% (T4), urea 1.5% + ZnSO4 1.00 % (T5), Urea 1.5% + ZnSO4 0.25% + Boron 0.25 % (T6), urea 1.5% + ZnSO4 0.50% + Boron 0.50% (T7), urea 1.5% + ZnSO4 1.00% + Boron 1.00 % (T8), Urea 1.5% + ZnSO4 0.25% + Boron 0.25% + MnSO4 0.2 % (T9), Urea 1.5% + ZnSO4 0.50% + Boron 0.50% + MnSO4 0.4 % (T10) and Urea 1.5% + ZnSO4 1.00% + Boron 1.00% + MnSO4 0.6 % (T11). The results revealed that the maximum shoot length (184.33 cm, 194.33 cm, 211.10 cm at 15, 30 and 45 days after spray respectively), maximum number of leaves per shoot (650, 670, 675 at 15, 30 and 45 days after spray respectively), maximum leaf area (33.13 cm2, 34.87 cm2 and 35.85 cm2 at 15, 30 and 45 days after spray respectively), minimum days taken to 50% flowering (6.5 days) and maximum fruit retention (41.16) were observed T11 (receiving Urea 1.5% + ZnSO4 1.00% + Boron 1.00% + MnSo4 0.6%). However, the maximum shoot girth (7.21 cm, 7.72 cm and 8.22 cm respectively), highest per cent of fruit setting (5.156), highest yield (33.63 kg) per tree , highest yield per hectare (93.15q) were obtained under T10 ( receiving Urea 1.5%+ ZnSO4 0.50% + Boron 0.50% + MnSO4 0.4%). The minimum values of observations were noted in control under the present studied.
