YIELD PERFORMANCE OF WHITE MAIZE (SAUWMT-9-3-4) UNDER VARYING FERTILIZER DOSES AND SPACING IN KHARIF-1 SEASON

Abstract

The experiment was conducted at the research farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207, Bangladesh during Kharif-1 season from 22 th March 2019 to 24 th June 2019 to study the yield performance of white maize (SAUWMT-9-3-4) under varying fertilizer doses and spacing in Kharif-1 season. The experiment comprised two factors, Factor A: Different fertilizer doses i.e. F = Recommended doses of fertilizer, F = 25% less than recommended doses of fertilizer, F 3 2 = 25% more than recommended doses of fertilizer and, Factor B: Three level of spacing i.e. S 1 = 60 cm × 20 cm, S 2 = 50 cm× 20 cm, S = 40 cm× 20 cm, The experiment was conducted following split plot design with three replications. Both the fertilizer dose and spacing level along with their Combined had significant effect on almost all vegetative and reproductive parameters. The highest values in plant heights (202.20 cm and 209.75 cm), highest leaf areas at lower (731.63 cm 3 2 and 733.26 cm ), at cob (762.27 cm 2 and 749.61 cm 2 ) and upper units (809.56 cm 2 and 573.34 cm ) plant -1 respectively found from F 3 S 1. The highest values in number of rows cob

(14.33), number of grain row -1 (30.78), and number of grain cob -1 (414.74) and 100 grain weight (34.70 g) were recorded from the treatment F 3 S . The highest grain yield, stover yield and biological yield (10.22, 11.27 and 21.49 t ha 2 -1 , respectively) were found from F 3 S 2 .
