Abstract

A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh, during the period from November 2021 to March 2022 to evaluate the influence of micronutrients management on growth and yield of two lentil varieties viz., BARI Masur-8 (V1) and Binamasur-8 (V2) and 6 micronutrients management (no fertilizer - F1, recommended fertilizer dose (RFD) (40-90-40-55 Kg ha1 of urea-TSP-MoP-Gypsum) with 10 Kg ha1 ZnSO4 as basal - F2, RFD with zinc (Zn) as foliar spray - F3, RFD with Zn and boron (B) as foliar spray - F4, 50% RFD + 50% cow dung (5 t ha1) - F5 and 50% RFD + 50% cow dung + Zn and B as foliar spray - F6). No significant effect had found for variety except 1000-seed weight but micronutrients management along with interactions significantly effects on all studied parameters of lentil. The higher 1000-seed weight (34.16 g) was recorded in BARI Masur-8. The highest plant height (37.09 cm), number of branches plant1 (7), dry weight of root plant1 (159.17 mg), dry weight of shoot plant1 (3319.33 mg) and number of pods plant1 (62) was observed at F6 treatment. The highest 1000-seed weight (31.68 g) were recorded at F2 treatment. The highest weight of nodules plant1 (10.33 mg at 60 DAS), seed yield (2.62 t ha1), straw yield (2.12 t ha1) and biological yield (4.74 t ha1) were found at F3 treatment. The highest plant height (38.45 cm), number of branches plant1 (7), number of pods plant1 (63), seed yield (2.91 t ha1) and harvest index (58.65%) were recorded at V2F6 whereas the highest weight of nodules plant-1 (26 mg), straw yield (2.22 t ha1) and biological yield (5.02 t ha1) were found at V1F3 but the highest 1000-seed weight (34.87 g) at V1F1. The highest number of seeds pod1 (1.83) was found at V2F1. So, two varieties showed similar performance on yield. Foliar application of Zn has the potentiality to increase seed yield. The variety Binamasur-8 with 50% RFD + 50% cow dung + Zn and B (F6) as foliar spray could bring maximum yield (2.91 t ha1) of lentil followed by treatment F2, F3, and F4.
