EFFECT OF NANOPRODUCT AND CARBENDAZIM ON GROWTH, YIELD AND YIELD COMPONENTS OF BORO RICE

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 0 – controlled (only water); T 1 – Carbendazim @ 2g L ii -1 ; T 2 –SNP2 @ 1.0 ml L – SNP2 @ 2.0 ml L -1 ; T 4 –SNP2 @ 3.0 ml L -1 ; T 5 – Carbendazim @ 2g L -1 -1 ; T 3 + SNP2 @ 1.0 ml L – Carbendazim @ 2g L -1 + SNP2 @ 2.0 ml L -1 ] 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.
