| dc.description.abstract | A field experiment was conducted at the Agronomy research field of Sher-e-Bangla Agricultural University in Dhaka from November 2019 to March 2020 to study the influence of biochar and Potassium on the enhancement of growth and yield of wheat (BARI Gom 31) under different irrigation regimes. In the experiment, the treatments consisted of four doses of biochar and Potassium viz. B0K0= 5 t ha Biochar + 0 kg ha -1 K, B1K1= 5 t ha -1 Biochar + 48 kg ha -1 K, B2K2= 5 t ha Biochar + 36 kg ha -1 K, B3K3= 0 t ha -1 Biochar + 48 kg ha -1 K and four different irrigation levels viz. I0 = Control, I1= Irrigation at crown root initiation stage, I2= Irrigation at crown root initiation stage + Flowering stage, I3= Irrigation at crown root initiation stage + Flowering stage + Grain filling stage. The experiment was laid out in 2 Factor Split Plot Design with three replications by assigning irrigation to main plot and biochar and Potassium to sub-plots. There were 16 treatments combination. The collected data were statistically examined to determine the effectiveness of the treatments. Results revealed that there were significant variations among the treatments in the most of the examined parameters. As for growth parameters, the highest plant height (87.42 cm), no. of tillers/plant (6.60), leaf area index (42.21) and for yield parameters, the highest ear length (17.01 cm), no. of spikelets/ear (18.13), no. of grains/ear (37.70), 1000-grain wt. (46.66 gm), grain yield (3.53 t 1 ), straw yield (3.56 t ha -1 ) and harvest index (49.80) were recorded under I2B2K2 due to irrigation at crown root stage and flowering stage interaction with Biochar: 5 t ha -1 and K: 36 kg ha -1 . On the contrary, lowest values for above mentioned cases were obtained with I0B0K0. The results revealed that irrigation at crown root initiation and at flowering stage with 5 t ha -1 biochar and 36 kg Potassium enhance both growth and yield of wheat. | en_US |
