Effect of microenvironment and nitrogen levels on growth and yield of cabbage Brassica oleracea var capitata and its simulation analysis

Abstract

The investigation entitled Effect of microenvironment and nitrogen levels on growth and yield of cabbage (Brassica oleracea var capitata) and its simulation analysis was initiated at Vegetable section, Research Farm, Bihar Agricultural University, Sabour, Bhagalpur, Bihar, India during 2017-18 to 2018-19. The experiment comprising of three dates of transplanting (D1 = 29 November 2017, D2 = 9 December 2017, D3 =19 December 2017), three nitrogen levels (N1=125 kg/ha, N2= 150 kg/ha), N3= 175 kg/ha) and three varieties (V1= Golden Acre, V2= Disha and V3= NS183) was laid out in Split-Split Plot Design (SPD) replicated three times comprised of twenty-seven treatment combinations. Crop simulation model (DSSAT v4.6) was used to describe yield predictability in a set of environment. newline
