Effect of integrated nutrient management on growth and yield of banana Cv. Grand Naine (AAA) (ratoon crop)

Abstract

The present investigation was carried out during 2018-2019 at Horticultural Research Station, Aswaraopet, Bhadradri Kothagudem district, Telangana State. The experiment was carried by planting tissue culture banana Cv. Grand Naine plants at spacing of 1.8x1.8m with eleven treatment combinations with different fertigation levels along with organics like arka microbial consortium, neem cake, jeevamrutha with and without bunch covering which was conducted as a integrated study for ratoon crop with Randomized Block Design (RBD) and replicated thrice. For the growth characters like pseudo stem height, after three and five months of ratooning the treatment T4 has recorded significantly highest at all the crop growth. The highest pseudo stem height (100.56 cm) was also recorded in T4 whereas lowest pseudo stem height (95.63cm) was noticed in T1. The likewise the other characters like pseudo stem girth, functional leaves, leaf length, leaf breadth, leaf area, leaf area index and number of suckers the results were found to be maximum in treatment which received 75 per cent fertigation with combination of all organic nutrients and minimum results were observed with Recommended Dose of Fertilizers (RDF). The maximum number of hands per bunch (10.74), highest finger length (18.80 cm) and finger girth (13.98cm) highest finger weight (138.09g) highest weight of hand (3.94 kg) highest yield per plant and per hectare (28.03 kg and 86.49t/ha) was noticed in While, the minimum results were obtained in T1. The integrated use of organics i.e, Arka Microbial Consortium (AMC), neem cake, jeevamrutha, panchagavya and inorganic nutrients through 75 per cent fertigation along with bunch protective measures has given the good results.
