Economic net returns per hectare area from the turmeric genotypes applied with nitrogen and potassium levels

Abstract

The fresh yield of rhizomes (101.72 q/ha) and dry matter recovery (37.39%) were found to be significantly higher in case of Roma genotype of turmeric over PCT-8 and Suroma. The genotype Suroma produced the significantly lowest turmeric yield (96.13 q/ha), 5.59 q/ha less than Roma. The dry matter recovery was also lowest (35.24%) in case of Suroma. The maximum fertility level (N200K200) recorded significantly higher fresh yield of rhizomes (100.90 q/ha) over all the remaining fertility levels. The treatment interactions were found to be non-significant for both these parameters. Amongst the three genotypes, Roma gave maximum net income up to Rs.474564/ha with B:C ratio 4.50. The second best genotype was PCT-8 giving net income up to Rs.461350/ha with B:C ratio 4.40.In case of fertility levels, the increasing fertility levels from N100K100 to N200K200 resulted in increase in net income as well as B:C ratio. Thus the maximum dose (N200K200) gave the highest net income of Rs.468560/ha, whereas it was only Rs.449210/ha from N100K100. Based on two years mean values, the extra net income from N200K200 over N100K100 was up to Rs.19350/ha. Similarly the net income was upto Rs.15870/ha from N200K150 over N100K100. The increased net income under highest NK level was due to increased rhizomes yield/ha which fetched higher market value.
