ABSTRACT
To study the “Fruit Characteristics and Yield of Mango cv. Amrapali as Influenced by Bio-enhancers and Bio-fertilizers” a field experiment was conducted in the Garden, Department of Horticulture, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.) during 2020-2021. The experiment consists of 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 (100 g/tree), FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Panchagavya (3%) + Azotobacter (100 g/tree), FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Jivamrit (20%) + Azotobacter (100 g/tree), FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Amritpani (20%) + PSB culture (100 g/tree), FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Panchagavya (3%) + PSB culture (100 g/tree), FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Jivamrit (20%) + PSB culture (100 g/tree) which were replicated thrice in randomized block design by using one plant as a unit per treatment. The application of different bio-enhancers and bio-fertilizers to mango plant was made as per the requirement of the treatment.The experimental results clearly revealed that the plants treated with the application of FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Panchagavya (3%) + Azotobacter (100g/tree) produced fruits with significantly higher length, width, weight, volume, pulp weight, pulp:peel ratio with more yield. However, the fruit with minimum fruit length, width, weight, volume, pulp weight, pulp:peel ratio, and yield were recorded from the plants treated with the application of FYM (25 kg/tree/year) + Organic mulch (Paddy straw) i.e., Control. Thus, on the basis of the above observations, this can be suggested that the application of FYM (25 kg/tree/year) + Organic mulch (Paddy straw) + Panchagavya (3%) + Azotobacter (100 g/tree) were effective for substantially higher physical fruit characteristics and yield under the sub-tropical plains of Central Uttar Pradesh, India.
ABSTRACT
A field experiment was conducted during two consecutive Rabi seasons 2020-21 and 2021-22 at Students’ Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, India. The field experiment allocated three irrigation scheduling namely: I1: two irrigations at CRI (crown root initiation) and Jointing stage, I2: three irrigations at CRI, Jointing and Booting stage and I3: Four irrigations at CRI, Tillering, Booting and Milking stage, two moisture conservation practices viz: M0: without mulching and M1: Organic mulch at the rate of 10 t ha-1 + Kaolin 6% spray and three nutrient management practices viz: N1: 100% Recommended dose of fertilizers (RDF) (150:60:40 kg ha-1 NPK), N2: 85% RDF + Farm yard manure (FYM) @ 5.0 t ha-1 and N3: 75% RDF + FYM @ 10.0 t ha-1. The field experiment was laid out in double split plot design with three replications. On pooled basis of two years experimentation the results indicated that, four irrigations at CRI, Tillering, Booting and Milking stage recorded significantly highest value of crop growth rate (CGR) (13.15 and 19.28 g m-2 day-1 at 30-60 and 60-90 days after sowing (DAS), respectively), grain yield (4381.60 kg ha-1) and consumptive use of water (457.39 mm) while, significantly highest water use efficiency (11.97 kg ha-1 mm) was received under two irrigations at CRI and Jointing stage over the rest of irrigation schedules. In respect of moisture conservation practices, organic mulch @ 10 t ha-1 + Kaolin 6% spray recorded significantly water use efficiency (11.41 kg ha-1 mm) compared to without mulching treatment while, highest consumptive use of water (380.72 mm) was recorded under without mulching. Integration of 85% RDF + FYM @ 5.0 t ha-1 recorded significantly maximum water use efficiency (10.99 kg ha-1 mm) compared to other treatments while, highest consumptive use of water (381.41 mm) was recorded under the treatment of 100% RDF.
