Abstract:

A study was conducted in new orchard, Department of Horticulture, Main Agricultural Research Station (MARS), College of Agriculture, University of Agricultural Sciences, Dharwad, Karnataka during 2014-15 and 2015-16 on “Integrated nutrient management studies in banana cv. Grand Naine (AAA)” to unravel the beneficial effects of application of organic manures and chemical fertilizers with green manure, Azospirillum and PSB. At the start of experiment, the organic carbon and available NPK were medium. After the completion of the experiment the results indicated that, the organic carbon was found to be enhanced in organic treatments (T1 to T5) from 0.65 % to 0.72 %, whereas it decreased from 0.65 % to 0.57 % in integrated treatments (T6 to T12). The available N and available potash in soil was significantly higher in organic treatments than integrated treatments. The available phosphorous was decreased in organic treatments compared to integrated treatments. Plants applied with T7 {Vermicompost equivalent to 40 % RDN (24.20 t/ha) + Urea equivalent to 40 % RDN (535.73 kg/ ha) + Green manure (sunnhemp @ 8.88 t/ha) and Azospirillum (30.86 kg/ha) equivalent to 20 % RDN + PSB (30.86 kg/ha)} recorded the highest NPK concentration in banana leaf, fruit and pseudostem at harvest (3.25%, 0.32% and 2.87 % in leaf, 3.27%, 0.32% and 3.15% in fruit and 3.43%, 0.34% and 3.02% in pseudo stem respectively). The highest and gross returns (Rs.4.97 lakh/ha) and moderate net returns (Rs.3.04 lakh/ha) was also recorded in T7 treatment
