Abstract
An experiment was
conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University,
Dhaka, Bangladesh during the period from March to June, 2016. The treatment
consisted of two factors: Factor A:
Three heat tolerant variety. viz; V1:
KSP-1700, V2: KSP-176, and V3: KSP-30. Factor B: Four levels of potassium
fertilizer. viz; F0: (control); F1: 80
kg K/ha; F2: 120 kg K/ha and F3: 160 kg K/ha. These three
varieties performed better with proper management of potassium fertilizers on
plant height, single bulb weight, fresh foliage weight, yield plot-1
and yield ha-1. The highest yield ha-1 (25.01 t) was recorded from V1K2
treatment combination.
