Abstract
Field trial was conducted to optimize the micronutrient application in lentil crop (Variety-WBL-77) at Regional Research Station (Old Alluvial Zone), Uttar BangaKrishi Viswavidyalaya, Majhian during 2019-20 and 2020-21. Foliar application of Fe, Zn and B (at 50 and 100 ppm each) were applied twice, first at pre anthesis stage and second at pod development stage. Parameters such as plant height (cm), dry matter (g/m2), number of nodules per plant and number of pods per plant were observed highest with T8(RDF+50 ppm Zn+Fe+B foliar spray) treatment whereas the T1 (RDF) showed the lowest value for each parameter. T3 (RDF+100 ppm Zn foliar spray) resulted with maximum 1000 seed weight (g). T8 (RDF+50 ppm Zn+Fe+B foliar spray) was also recorded with the highest seed yield (kg/ha), stover yield (kg/ha). Both T7 (RDF+100 ppm B foliar spray) and T8 (RDF+50 ppm Zn+Fe+B foliar spray) treatments were resulted with the same value of harvest index followed by the rest of the treatments. Therefore, the treatment T8 (RDF+50 ppm Zn+Fe+B foliar spray) proved best among the treatments selected and can be recommended for lentil (Variety-WBL-77).
