Abstract

A field experiment was conducted for two consecutive seasons to study the effect of Bradyrhizobium inoculation, farmyard manure (FYM), nitrogen (urea) and inoculation plus farmyard manure on growth and yield of guar crop. Four Bradyrhizobium strains were used to inoculate guar seeds (USDA3089, USDA3385, USDA3386 and ENRRI 16A) and two levels of farmyard manure, i.e. 5 (FYM1) and 10 (FYM2) ton ha¯¹. Results indicated that combining Bradyrhizobium inoculation with FYM significantly increased plant height, shoot dry weight, pod dry weight, yield and phosphorus (P) percentages compare to the control and Bradyrhizobium inoculation. However, Bradyrhizobium inoculation significantly increased plant height, shoot dry weight and pod dry weight compare with the control. Sole FYM2 treatment significantly increased shoot dry weight, pod dry weight, plant height, seed yield and seed P percent compare with the control and Bradyrhizobium inoculation. Urea application showed similar results to that of FYM2 except that urea had no significant effect on seed P percent. In conclusion, combined application of FYM and Bradyrhizobium inoculation could be a useful practice in sustaining the growth and yield of guar.
