Abstract:
A field experiment was conducted to assess the effect of integrated nutrient
management on the growth and yield of NERICA 10 at the research farm olSher-eBangla
Agricultural University, Dhaka, Bangladesh during Aus season (Mid MarchJuly),
2012. 100 kg N form urea and 20 kg N substituted by vermicompost (T
3
Treatment) produced the maximum yield and yield attributing characters of NI2RICA
10. But the eflèct of vermicompost along with nitrogenous fertilizer was the most
pronounced than that of cowdung or nitrogenous fertilizer alone. Similar effects were
also observed on N. P. K, S content and their uptake by NERICA 10. The effect of
100 kg N from urea along with 20 kg N from vermicompost (T
3 Treatment) was
statistically identical to 100 kg N from urea with 20 kg N substituted by cowdung (1
4
Treatment), 80 kg N from urea with 40 kg N substituted by vermicompost (T
5
Treatment). 80 kg N from urea with 40 kg N substituted by cowdung (T
6
Treatment).
60 kg N from urea with 60 kg N substituted by vermicompost (Ti Treatment), 40 kg
N from urea with 80 kg N substituted by vermicompost (1
9
Treatment) and 100% N
substituted by equal portion of vermicompost and cowdung (Ti
l Treatment). The
effect of 100 kg N from urea along with 20 kg N from vermicompost (T
3 Treatment)
Treatment). 100% recommended N i.e. 120 kg
nitrogen / ha (T
2
Treatment). 60 kg N from urea with 60 kg N substituted by cowdung
was
dissimilar with Control
(Ti
(18 Treatment) and 40 kg N from urea with 80 kg N substituted by cowdung (Ti
o
Treatment). In post harvest soils, the contents of total nitrogen, available phosphorus.
exchangeable potassium and available sulphur increased due to application of
cowdung and vermicompost compared to initial soil. In the contrary, soil p1l value
decreased slightly as compared to that of initial soil. The overall resulLs indicate that
100 kg N from urea along with 20 kg N from vermicompost was the best treatment in
producing higher rice yield with sustenance of soil fertility.
