Abstract:
The study was conducted to evaluate to
effectiveness of Bio fertilizer and combined
inorganic fertilizer on growth and yield of radish
(Raphanus sativus L). This study was designed
with five treatments having ten replicates.
Treatments are T1-(Control); Recommended
amount of chemical fertilizer by Department of
Agriculture (RDOA), T2-1/2 RDOA of urea
+Recommended amount of Triple super
phosphate and Muriate of potash +250ml/ha Bio
fertilizer, T3-1/2 RDOA of urea + TSP&MOP
+500ml/ha Bio fertilizer, T4-1/2 RDOA of urea +
TSP & MOP + 750ml/ha Bio fertilizer, T5 -1l/ha
Bio fertilizer alone. All other agronomic practices
were followed based on DOA recommendation.
Plant height, number of leaves, leaf area were
measured by in weekly interval. Fresh weight of
and, dry weight of leave, storage root length and
diameter, fresh weight and dry weight of storage
root were measured at the time of harvesting (6th
week after planting). Analysis of variance was
performed to determine significant difference
among treatment (p<0.05). The results revealed
that treatments combining inorganic fertilizers
with biofertilizer (T3 and T4) significantly
enhanced plant growth and tuber yield compared
to inorganic fertilizers alone (T1) as well as
biofertilizers alone (T5). The highest tuber yield
was observed in T4, demonstrating the
effectiveness of biofertilizers in improving nutrient
uptake, root elongation, and soil microbial
activity. These findings suggest that integrating
biofertilizers with inorganic fertilizers can
enhance radish productivity while reducing the
environmental impact of excessive chemical
fertilizer use.
