Response of Integrated Dose of Plant Nutrients to Vegetative and Reproductive Growth and Yield of Tissue Cultured Banana

Abstract

To assess the response of integrated dose of plant nutrients to vegetative and reproductive growth and yield of tissue cultured banana (Musa paradisiaca L.) var. Grand Naine, a field experiment was conducted at Horticulture Garden, Department of Fruit Science, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (Uttar Pradesh), India, during the cropping season 2019-2020. The experiment was laid out in randomized block design using three replications and eleven treatmentsviz.,T1-100% RDF of NPK (110 + 30 + 330g NPK), T2-75% RDF of NPK + 50g Azotobacter + 50g PSB + 50g T. harzianum, T3-50% RDF of NPK + 50g Azotobacter + 50g PSB + 50g  T. harzianum, T4-25% RDF of NPK + 50g Azotobacter + 50g PSB + 50g T. harzianum, T5-75% RDF of N + 100% RDF of PK + 50g Azotobacter +50g PSB + 50g T. harzianum, T6-50% RDF of N + 100% RDF of PK + 50g Azotobacter + 50g PSB + 50g T. harzianum, T7-75% RD of K + 100% RDF of NP + 50g Azotobacter + 50g PSB + 50g T. harzianum, T8-50% RD of K + 100% RDF of NP + 50g Azotobacter + 50g PSB + 50g T. harzianum, T9-75% RDF of P + 100% RDF of NK + 50g Azotobacter + 50g PSB + 50g T. harzianum, T10-50% RDF of P + 100% RDF of NK + 50g Azotobacter + 50g PSB + 50g T. harzianum and T11-Control (without any fertilizers). Results obtained from the present study clearly showed that plants supplied with 75% Recommended dose Fertilizer of NPK (Nitrogen, Phosphorus and Potash) + 50g Azotobacter + 50g Phosphate solubilizing bacteria  + 50g Trichoderma harzianum, produced the highest pseudostem height (158.64cm), girth (71.26cm), total number of leaves (35.10), number of functional leaves (18.12), length of inflorescence (120 cm), minimum number of days from planting to flowering (251), number of days from flowering to harvesting (95.33), with maximum bunch weight (26.75 kg), number of fingers per bunch (176.05), number of hands per bunch (8.66), number of fingers per hand (20.33), finger weight (154.18 g), finger length (21.66 cm), finger diameter (16.50 cm) and yield (66.87 t/ha).
