RESPONSE OF WHEAT (Triticwn aestivum L.) ON BORON FERTILIZATION

Abstract

The experiment was carried out in Sher-e-Bangla Agricultural University. I)haka during the period from December 2011 to April 2012 to observe the response of wheat to boron fertilization. The experiment comprised four levels of boron (0. 1.0. 1.5 and 2.0 kg B ha'). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different yield contributing characters and yield were recorded and statistically significant variation was recorded for ditThrent levels of boron. At 30-70 DAS and at harvest the longest plant (23-90 em) and the maximum number of tillers plani' (2.37-5.40) was recorded from 2.0 kg B haS'. while the shortest plant (17.6-74.18 cm) and minimum number of tillers plant' (1.8-3.77) from 0 kg B hi'. The highest number of spikelets spike' (21.67) was recorded from 2.0 kg B ha'. whereas the lowest number (18.83) from 0 kg B hi'. The highest number oftotal grains spike' (52.06) was recorded from 2.0 kg Bhi'. while the lowest number (35.87) was found from 0 kg B ha'. The highest 1000-seed weight (44.79 g) was obtained from 2.0 kg B ha' and the lowest (40.31 g) from 0 kg B ha1. The highest grain yield hectare1 (3.88 ton) was observed from 2.0 kg B ha1. while the lowest (3.14 ton) was found from 0 kg B ha'. The highest straw yield hectare1 (4.96 ton) was observed from 2.0 kg B ha', whereas the lowest (3.49 ton) from 0 kg B hi'. In grain sample. the highest N. P. K and B content was thund from 2.0 kg 13 ha' (0.139. 0.36. 0.47 and 0.83% respectively), while the lowest values were obtained from control (0.103. 0.28, 0.34 and 0.64% respectively).
