Effect of Bio-enhancers and Bio-Fertilizers on Growth and Quality of Mango cv. Amrapali under Sub-tropical Plains of Central Uttar Pradesh, India

A Field experiment was conducted in the Garden of Department of Horticulture, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.) during 2020-2021. The experiment was laid out in randomized block design with seven treatments i.e., FYM (25 kg/tree/year) + Organic mulch (Paddy straw) i.e., Control, FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Amritpani (20%) + Azotobacter (100g/tree), FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Panchagavya (3%) + Azotobacter (100g/tree), FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Jivamrit (20%) + Azotobacter (100g/tree), FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Amritpani (20%) + PSB culture (100g/tree), FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Panchagavya (3%) + PSB culture (100g/tree), FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Jivamrit (20%) + PSB culture (100g/tree) which were replicated thrice using one plant as a unit per treatment. The mango cultivar “Amrapali” was treated with different organic materials like farm yard manure, organic mulch (Paddy straw), Azotobacter, PSB culture, Panchagavya (3%), Jivamrit (20%) and Amritpani (20%) respectively and compared with the control.

The experimental results revealed that plants treated with the application of FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Panchagavya (3%) + Azotobacter (100g/tree) recorded a significantly higher number of leaves per shoot, number of inflorescence per branch, maximum TSS, total sugar content, sugar: acid ratio and is at par with application of FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Panchagavya (3%) + PSB culture (100g/tree) (14.67) and FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Jivamrit (20%) + Azotobacter (100g/tree). Thus, on the basis of the above observations, this can be suggested that for getting substantially more vegetative growth and quality fruits, the application of FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Panchagavya (3%) + Azotobacter (100g/tree) should be made under the sub-tropical plains of Central Uttar Pradesh, India.
