Analysis of Physio-Genetic Traits for Drought Tolerance in Maize (Zea mays L.)

Soil profile studies was conducted in Baragaon Nandur Village, four soil orders viz two entisols, one inceptisols, vertisols were analyzed for chemical properties which are derived from basalt, basaltic alluviam and slightly conditioned by topography. Calcium was ranged from 22.30, 19.70 to 23.78, 18.20 to 26.51, 17.5 to 25.5 cmole (p+) kg-1 in Entisols (A), Entisols (B,) Inceptisols, and Vertisols, soils respectively. In case of magnesium it wasranged from 14.75, 8.86 to 13.58, 8.75 to 16.47, and 9.23 to 13.33 cmole (p+) kg-1. in Entisols (A), Entisols (B), Inceptisols, Vertisols, soil pedons respectively.Available sulphur in the soil was 10.75 mg kg-1in Entisols (A), and it was ranged from 7.54 mg kg-1 to 15.75 mg kg-1 In Entisols (B). While in Inceptisols it was ranged from 10.37 to 14.12 mg kg-1 and inVertisols this range was 6.37 to 24.5 mg kg-1.The value of DTPA extractable Fe ranged from 2.04 to 3.07 mg kg-1 in Entisols (B), 4.10 to 4.25 mg kg-1 in Inceptisols, 2.07 to 5.81 mg kg-1 in Vertisols and 4.33 mg kg-1 in Entisols (A). DTPA extractable Mn content of Entisols (A) was 4.42 mg kg-1.Entisols (B) was ranged from 2.29 to 3.50 mg kg-1. Manganese content in Inceptisols ranged from 3.19 to 4.98 mg kg-1. in Vertisols it was ranged from 2.30 to 4.90 mg kg-1.Zinc content was 0.49 mg kg-1 in Entisols (A) and it was ranged from 0.24 to 0.32 mg kg-1, 0.28 to 0.53 mg kg-1, and 0.38 to 0.45 mg kg-1, in Entisols (B), Inceptisols and Vertisols respectively. Copper content in Entisols (A), Entisols (B), Inceptisols, and Vertisols, ranged from 1.18, 0.44 to 0.92 mg kg-1, 1.73 to 2.46 mg kg-1, and 1.56 to 2.07 mg kg-1respectively.The present investigation was undertaken to generate comprehensive information about the characteristics of soil for evolving proper soil and water management strategies so as to maximize and sustain agriculture production.
