Study of Various Rootstocks and Scion on Leaf Nutrient Status in Mango (Mangifera indica L.)

Abstract

The current experiment, entitled “Study of various rootstocks and scions on leaf nutrient status in mango (Mangifera indica L.)” The experiment was framed in RBD (Randomized Block Design) with three replications studied for leaf nutrient analysis. The combination of five rootstocks and three scions, was carried out in the Department of Horticulture (Fruit and Fruit Technology), Bihar Agricultural University, Sabour, Bhagalpur, Bihar, during 2020–21 to evaluate the best combination regarding leaf nutrient content. The appropriate rootstock allows sufficient intake of nutrients and movement while additionally allowing for lesser fertilizer treatment rates, decreasing the possibility of leaching nutrients and toxicity while preserving fruit quality and yield. The analysis of the experiment macronutrient data related to N: P: K content in the leaf of the scion with the influence of different rootstocks has been presented in Table 1. The highest percentage of nitrogen, phosphorus and potassium were observed respectively treatments i.e. T7: Zardalu grafted on Olour (1.62%); T9: Bombay Green grafted on Olour (0.19 %); and T15: Bombay Green grafted on Mahmood Bahar (0.76%), whoever the investigation of micronutrients (Cu, Fe, Mn, and Mg) in leaves of different treatments of rootstocks has been presented in Table 2. The maximum value of copper, iron, manganese and magnesium content of leaf was observed respectively in the treatments i.e. (T13) Zardalu when grafted on Mahmood Bahar (38.33 ppm), (T8) Zardalu grafted on Mylepalium (109.00 ppm), (T4) Zardalu grafted on Mylipalium (0.24 ppm) and (T4) Zardalu grafted on Mylepalium (0.24ppm).
