Abstract:
An experiment was conducted during the period of November 2016 to April 2017 at
Agronomy farm of Sher-e-Bangla Agricultural University Dhaka-1207, Bangladesh to
evaluate the impact of nitrogen, phosphorus and biofertilizer on nodulation, growth
and yield of chickpea. Treatment consisted of two levels of biofertilizer i.e.
B0=without biofertilizer, B1= biofertilizer (80 g/1.2 kg seed); and six levels of
fertilizer i.e. F0= all fertilizer (MoP=18 g/plot, Boric acid=5.4 g/plot) except N & P,
F1=50% less N & P (urea=11.25 g/plot, TSP= 20.25g/plot, MoP==18 g/plot and boric
acid=5.4g/plot), F2= 25% less N & P (urea=16.87 g/plot, TSP=30.37 g/plot, MoP=18
g/plot and boric acid=5.4 g/plot), F3= recommended dose of N & P with others
(urea=22.5 g/plot, TSP=40.5 g/plot, MoP=18 g/plot and boric acid=5.4 g/plot),
F4=25% higher N & P (urea=28.12 g/plot, TSP=50.62 g/plot, MoP=18 g/plot and
boric acid=5.4 g/plot), F5= 50% higher N & P (urea=33.75 g/plot, TSP=60.75 g/plot,
MoP=18 g/plot and 5.4 g/plot). The experiment was laid out in a spilt plot design with
three replications. Result revealed that the highest values of vegetative growth i.e.
plant height, number of branches plant
-1
, plant dry weight, nodule number, nodule dry
weight, and yield and yield contributing character i.e. number of seeds pod
(1.35),
1000 seeds weight (438.73 g), seed yield (2078.61 kg ha
-1
), stover yield 2228.00 kg
ha
-1
) and harvest index (33.82%) were highest in B1 (biofertilizer) and F4 (1.75,
432.93g, 2055.00 kg ha
-1
, 2251.33 kg ha
-1
and 32.86 %, respectively) fertilizer. This
combination also showed the best result for all vegetative and reproductive growth
and development. Therefore, B1 (biofertilizer), F4 (25% higher than recommended N
&P) and the combine effect B1F4 could be used to cultivate chickpea.
