Abstract:
The present investigation entitled “Influence of foliar application of micronutrients on physical and yield attributes of mrig bahar guava (Psidium guajava L.) cv. Sardar” was carried out at College of Agriculture, Golegaon under VNMKV, Parbhani, M.S. (India) during year 2020-21. The experiment was laid out in Randomized Block Design having eleven treatments with three replications. The details of treatments were as T₁: Control treatment, T_2: zinc sulphate 1.0%, T_3: copper sulphate 1.0%, T₄: boron 1.0%, T₅: magnesium sulphate 1.0%, T₆: zinc sulphate 1.0% + magnesium sulphate 1.0%, T₇: copper sulphate 1.0% + magnesium sulphate 1.0%, T₈: zinc sulphate 1.0% + boron 1.0%, T₉: copper sulphate 1.0% + boron 1.0%, T_10: magnesium sulphate 1% + boron 1.0% and T_11: zinc sulphate 1.0% + boron 1.0% + copper sulphate 1.0% + magnesium sulphate 1.0%.The maximum fruit width (6.50cm), fruit weight (240.46 g) and fruit volume (197.93ml) were recorded under T₈ (zinc sulphate 1.0% + boron 1.0%) while highest number of fruits per plant (98.00) with treatment T₁₁ (zinc sulphate 1.0% + boron 1.0% + copper sulphate 1.0% + magnesium sulphate 1.0%).The maximum yield per tree (19.75 kg) and yield per hectare (219.43 q/ha) were recorded in T₁₁ treatment (zinc sulphate 1.0% + boron 1.0% + copper sulphate 1.0% + magnesium sulphate 1.0%).
