Abstract:
An experiment was conducted at the farm of Sher-e-Bangla Agricultural University, Dhaka
during the period of December, 2019 to May, 2020 with a view to study on the effect of Stalwart
Nano Product (SNP2) and a commercial fungicide (Carbendazim) on growth, yield and yield
components of Boro rice. The experiment was carried out in a Randomized Complete Block
Design (RCBD) with three replications. Two rice varieties (BRRI dhan28 and BRRI dhan63)
and the Nanoproduct with or without Carbendazim [07 levels of which were denoted by T

] were considered as factors of the experiment.
Analysis of variances were done through CROPSTAT software and significant levels of
treatments were judged at 5% level of probability. The mean separation test was done by LSD
at 5% level of significance. Matrix ranking, and scoring were done for placing performances
of treatments in order by relating to the scores to the weight given to different data obtained
from parameters studied. Results revealed that BRRI dhan63 showed higher result than BRRI
dhan28 in respect of grain yield (6.11 t ha
-1
) as evidenced by the highest dry matter
accumulation (g) and lower unfilled grains panicle
-1
. As an individual effect of the
Nanoproduct, the highest grain yield (5.74 t ha
-1
) was shown by T
5
due to reflection of the
highest no. of total tillers hill
-1
, effective tiller hill
-1
and filled grains panicle
-1
. However, in the
case of combined effect of treatments, the uppermost level of grain yield (6.35 t ha
) was
recorded in BRRI dhan63 treated with T
5
treatment. In this case the best result was facilitated
due not only to the highest effective tillers per hill with filled grains per panicle but also the
lowest number of non-effective tiller and unfilled grains per panicle recorded in our study.
Result also revealed that the use of the Nanoproduct boosted up yield comparing to the control
treatment (T
0
) in both varieties under study.
