EFFECTS OF BORON AND ZINC ON THE GROWTH, YIELD AND NUTRIENTS CONTENT OF LENTIL

Abstract

An experiment was carried out at the research farm of Sher-e-Bangla Agricultural University, Dhaka and chemical analysis was carried out in the Soil Science Division of Bangladesh Agricultural Research Institute (BAR!), Joydebpur, Gazipur during the period from November 2016 to March 2017 to evaluate the effect of three levels of boron viz., 0, 2,4 kg B -I -I ha and zinc viz., 0, 5, 10 kg Zn ha on growth and yield and nutrients content of lentil (BARI Masur-5). The maximum plant height (31.18 cm) at harvest, branches plani' (28.73) at harvest, pods plant' (79.13) at harvest, seed yield (1140.20 kg ha-'), stover yield (1649.73 kg ha"), 1000 seed weight (23.02 gm) were achieved by 2 kg ha" B and 5 kg ha' Zn The highest amount (4.780 %) of nitrogen content was observed in lentil when the field was fertilized with the dose of boron and zinc 4 kg ha4 B and 0 kg Zn ha" The highest amount of phosphorus content (0.768 %) was found under treatment 0 kg ha" B and 5 kg Zn ha-1 .The highest amount (1.707 %) of potassium content were observed in lentil when field was fertilized with the dose of 2 kg ha B and 5 kg Zn ha" .The highest amount (10.08 ppm) of boron content was observed in Lentil when the field was treated with 4 kg ha-1 B and 5 kg Zn ha-1 .The highest amount (62.03ppm) of zinc content was observed in lentil when the field was treated with 2 kg ha-1 B and 10 kg Zn hi'.
