A field experiment was conducted during 2006–07 to evaluate the effect of different irrigation systems and fertilizer levels on the physico chemical properties of the soil and pod yield of pea on gravelly loam (Typic Eutrocrept) soil of Nauni, located in the sub-humid sub-tropical zone of Himachal Pradesh. It was observed that soil physico-chemical properties responded significantly to the interactive effect of fertilizer levels and the irrigation systems. The study revealed that flood irrigation increased the pH (from 5.86 to 6.34 in surface soil and from 6.33 to 6.51 in sub surface soil) and EC (from 0.13 to 0.15 dSm−1 in surface soil and from 0.14 to 0.17 dSm−1 in sub surface soil) but decreased the CEC from 9.73 to 9.27 cmol (p+) kg−1 in surface soil and from 9.72 to 9.63 cmol (p+) kg−1 in subsurface soil. Double of the recommended dose of FYM resulted in maximum organic carbon percentage in the soil (1.26 and 1.13% in surface and subsurface soil respectively). Significant increase in the availability of N, P and K in soil was recorded with increase in the fertilizer dose. Drip irrigation+ fertigation resulted in increased content of exchangeable Ca, Mg and S in the soil. Application of the recommended dose of NPK through fertigation gave significantly higher pod yield than all other interactions.
