Abstract
Turmeric is known for its use in medicine, cosmetics, food and textile industries. The present investigation was carried out at farmer’s field, Byadamudlu village, Chamarajanagara district, Southern Dry Zone of Karnataka to study the influence of specific nutrient management practices on nutrient uptake, growth, yield and quality of turmeric in turmeric - muskmelon cropping sequence. The experiment was laid out in a randomized complete block design with fourteen treatments and three replications. Significantly higher growth, yield parameters and fresh rhizome yield (34.07 t ha-1) were
recorded on application of fertilizers recommended by the University of Agricultural Sciences, Bangalore (UAS-B) along with microbial consortia (MC), a bio-fertilizer and arka actino plus (AAP), a bio-pesticide. Higher curcumin (5.257 %) and essential oil (5.424 %) were registered due to treatment T14 (N150P125K250 -100% UAS (B) rec. +MC+AAP). Total nutrient uptake by turmeric was higher in treatment T14. Nutrient management practice which include MC+AAP along with N150P125K250 (T14) recorded maximum soil microbial population and enzymatic activity at all intervals. Higher soil
available nutrients (N, P2O5 and K2O) viz., 232.3, 72.34 and 476.7 kg ha-1 were recorded in T3, T2 and T11, respectively at harvest of turmeric. Nutrient use efficiencies of nitrogen (63.72 %), phosphorus (37.17 %) and potassium (79.26 %) were higher in T14. The residual effect of treatment T14 was superior in terms of better growth parameters, fruit yield (17.87 t ha-1) and nutrient uptake by muskmelon. Higher soil microbial population and enzyme activity after harvest of muskmelon were registered due to residual influence of treatment T14. Higher gross returns for the entire cropping sequence was ` 6,90,270 with benefit cost ratio of 3.2:1 was recorded in treatment T14. N150P125K250 -100% UAS (B) rec. +MC+AAP is recommended for turmeric in turmeric - muskmelon cropping sequence in Southern Dry Zone of Karnataka.
