Abstract/ Executive Summary:

A study was conducted in Calcareous Low Ganges River Floodplain Soil (AEZ 12) at Regional Pulses Research Station (RPRS), Madaripur during the Rabi season of 2013-14. The objectives were to evaluate the effect of zinc (Zn) and boron (B) on the yield and yield contributing characters of field pea (Pisum sativum) and to estimate the optimum dose of Zn and B for yield maximization. There were 25 treatment combinations comprising five levels each of boron (0, 1.0, 1.5, 2.0 and 2.5 kg ha^-1) and zinc (0, 1.0, 2.0, 3.0 and 4.0 kg ha^-1) along with a blanket dose of N₂₀ P₁₆ K₃₀ S₁₀ kg ha^-1 was used. The experiment was laid out in RCBD factorial with three replications. Results showed that the combination of B_2.0Zn_3.0was produced significantly higher seed yield (1074 kg ha^-1). The lowest seed yield (744 kg ha^-1) was found in control (B₀Zn₀) combination. The combined application of zinc and boron were observed superior to their single application. Therefore, the combination of B_2.0Zn_3.0may be considered as suitable dose for field pea cultivation in Bangladesh.

Keywords: Zinc, Boron, Field pea, Floodplain Soil

Location: Regional Pulses Research Station (RPRS), Madaripur

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Crop-Soil-Water Management

Objectives:

(i) To evaluate the response of Zn and B on the yield and yield contributing characters of field pea.

(ii) To find out a suitable dose of Zn and B for the maximization of field pea yield.

Methodology:

A study was conducted in Calcareous Low Ganges River Floodplain Soil (AEZ 12) at Regional Pulses Research Station (RPRS), Madaripur during the Rabi season of 2013-14. There were 25 treatment combinations comprising five levels each of boron (0, 1.0, 1.5, 2.0 and 2.5 kg ha^-1) and zinc (0, 1.0, 2.0, 3.0 and 4.0 kg ha^-1) along with a blanket dose of N₂₀ P₁₆ K₃₀ S₁₀ kg ha^-1 was used. The treatments were arranged viz. T₁= B₀ Zn₀; T₂= B_1.0 Zn₀; T₃= B_1.5 Zn₀; T₄= B_2.0 Zn₀; T₅= B_2.5Zn₀; T₆= B₀ Zn_1.0; T₇₌B_1.0 Zn_1.0; T₈= B_1.5 Zn_1.0; T₉= B_2.0 Zn_1.0; T₁₀= B_2.5 Zn_1.0; T₁₁= B₀ Zn_2.0; T₁₂= B_1.0 Zn_2.0; T₁₃= B_1.5 Zn_2.0; T₁₄= B_2.0 Zn_2.0; T₁₅= B_2.5 Zn_2.0; T₁₆= B₀ Zn_3.0;T₁₇= B_1.0 Zn_3.0; T₁₈= B_1.5 Zn_3.0;T₁₉= B_2.0 Zn_3.0;T₂₀= B_2.5 Zn_3.0;T₂₁= B₀ Zn_4.0;T₂₂= B_1.0 Zn_4.0;T₂₃= B_1.5 Zn_4.0;T₂₄= B_2.0 Zn_4.0and T₂₅= B_2.5 Zn_4.0.Before setting the experiments, initial soil samples were collected from the experimental field from 0-15 cm depth and the collected samples were analyzed for chemical properties using standard procedures in the laboratory. The experiment was laid out in RCBD factorial with three replications. The unit plot size was 3 m × 2 m. Blanket dose of fertilizers N₂₀ P₁₆ K₃₀ S₁₀ kg ha^-1were applied at the time of final land preparation. The land was prepared thoroughly by a tractor driven Siegel and rotavator. Boron and zinc were applied as boric acid and zinc sulphate in the respective treatments plot during final bed preparation. Seeds (BARI Field pea-1) were sown @ 30 kg ha^-1 with a spacing of 40 cm x 05 cm on 14 November, 2013. Two weeding were done at 20 and 40 days after sowing (DAS). Intercultural operations were done properly. Crop was harvested after maturity. Yield contributing characters were recorded from 10 randomly selected plants from each plot. Yield (kg ha^-1) was recorded from the whole plot technique. The data were then statistically analyzed by using MSTAT-C.
