Abstract:
Detail information about optimum level of N fertilizers application and superior okra
cultivar is limited. The response of three cultivars of okra [Abelmoschus esculentus (L.)
Moench] viz. BARI Dherosh 1, Arka anamica and Shatdari to nitrogen (N) levels (0,
59.8, 64.4, 69.0 and 73.6 kg N/ha) were examined by using Randomized Complete Block
Design (RCBD) with three replications at the Horticultural Farm of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207, during the period from
March to June, 2005. Yield increased with increasing the N levels. The three cultivars
performed best in both yield and yield contributing characters at the highest N level 73.6
kg N/ha. The highest yield was recorded from Arka anarnica (17.3 t/ha) followed by
BARI Dherosh I (15.3 tlha) and Sbatdari (9.4 t/ha) at 73.6 kg N/ha. The cultivar Arka
anamica and N level 73.6 kg/ha is the suitable combination for successful okra
cultivation.
