INFLUENCE OF FOLIAR APPLICATION OF ZINC AND BORON ON THE GROWTH AND YIELD OF LENTIL

Abstract

An experiment was carried out at the Agronomy Farm of Sher-e-Bangla Agricultural University, Dhaka to evaluate the influence of foliar application of zinc (Zn) and boron (B) on the growth and yield of lentil during the period from November 2017 to March 2018. Zn and B were applied as foliar application in different combinations such as F 0 = Control (without Zn and B), F 1 = Zn foliar application, F 2 = B foliar application and F 3 = Zn and B foliar application at four growth stages, i.e S 0 = control (without Zn and B), S 1 = at 10 leaf stage, S 2 = at 10 leaf stage + flowering and S 3 = at 10 leaf stage + flowering + pod formation were considered for the present study. The experiment was laid out in split plot design with three replications. Data on different growth and yield parameters were recorded and analyzed statistically by using MSTAT-C software program. The level of significance among the treatments was estimated by the Duncan’s Multiple Range Test (DMRT) at 5% level of probability. The result revealed that application of Zn and B (F 3 ) as foliar spray was superior in producing highest yield (1701.7 kg ha ), as well as higher growth and yield attributes characters. In case of foliar application at 10 leaf + flowering + pod formation stage showed highest yield (1701.3 kg ha ) yield attributes and growth characters. On the other hand, treatment combination of F 3 S 3 (Zn and B foliar application with combination of time of application at 10 leaf stage + flowering + pod formation) showed the highest plant height (38.28 cm), dry weight plant -1 1 (9.33), number of pods plant -1 -1 (26.29 g), number of branches plant (52.44), number of seeds pod -1 (2.12), shelling percentage (43.24%), 1000 seed weight (22.49 g), seed yield (1852.0 kg ha ), stover yield (1956.3 kg ha -1 ) and biological yield (3808.3 kg ha -1 ) where lowest result on the respected parameters were obtained from the treatment combination of F 0 S 0 (without Zn and B).
