Impact of Bio-fertilizer on Growth Parameters and Yield of Potato

Abstract

Application of different bio-fertilizers alone or in combination with others as seed, soil and foliar spray revealed that the bio-fertilizers have stimulatory effect on germination, sprouting behaviour and growth parameter of potato. The maximum germination and number of bud with 5 in number per tuber was recorded from T7 treatment in which treatment was given as soil application FYM @ 150gm/pot + Mustard cake @ 150 gram/pot + tuber treatment with T. viride + foliar spray with bio-formulation of T. viride. It was also cleared that bio-fertilizers have stimulatory effect on vigour of plants. The maximum plant height was recorded in treatment T7 (soil application of mustard cake + tuber treatment and foliar spray with T. viride) with the value of 11.16cm at 30 day age of plant followed by treatment T4 (soil application of mustard cake + tuber treatment and foliar spray with Azotobacter), T1 (soil application of neem cake + tuber treatment with PSB), representing value of 11.06cm and 10.73cm, respectively. The effect of seed treatment and foliar spray with bio-fertilizer on tuber size and yield was recorded that maximum number of large size tubers (5) and yield (844.85gm) was found in T7 treatment, where treatment was given as soil application FYM @ 150gm/pot + mustard cake @150gm/pot + tuber treatment with T. viride + foliar spray with bio-formulation of T. viride
