Abstract/ Executive Summary:

Total dry matter at 73 DAS at maturity was the highest in the treatment T₈in which B and Mo was applied @ 1 kg ha^-1 as basal in addition to NPKS. The yield and yield attributes showed significant differences due to different treatments. However, the treatment T₈had maximum grain yield 4.87 g plant ^-1 followed by T₉ and T₁₃. The treatment T₁ produced the lowest grain yield 1.63 g plant^-1. Similarly, the treatment T₈had maximum straw yield 2.28 g plant ^-1 followed by T₉ and the treatment T₁ produced the lowest straw yield 0.70 g plant^-1. The higher yield in the treatment T₈was contributed by higher number of pods plant ^-1 and 1000 grain weight.

Keywords: Yield, Boron, Molybdenum and Mungbean

Location: BINA HQ, Mymensingh

Start Date: 15-03-2007

End Date: 30-06-2007

Program Area: Crop-Soil-Water Management

Commodity: Mungbean

Objectives:

To assess the effect of micro-nutrients boron and molybdenum on the growth and yield of mung bean

Methodology:

A pot experiment was conducted on the growth and yield of mung bean. The experiment was consisted of 13 treatments viz., T₁ = control (absolute), T₂ = NPKS ( 15, 25, 30 and 15 kg ha^-1, recommended dose for deficit low soil but high yield goal), T₃ = NPKS+ basal dose with boron @ 1 kg ha^-1, T₄ = NPKS+ basal dose with boron @ 2 kg ha^-1, T₅ = NPKS+ basal dose with boron @ 3 kg ha^-1, T₆= NPKS+ basal dose with molybdenum @ 1 kg ha^-1, T₇ = NPKS+ basal dose with molybdenum @ 2 kg ha^-1, T₈ = NPKS+ basal dose with boron and molybdenum @ 1 kg ha^-1, T₉ = NPKS+ basal dose with boron and molybdenum @ 1 kg ha^-1 and 2 kg ha^-1, T₁₀ = NPKS+ basal dose with boron and molybdenum @ 2 kg ha^-1 and 1 kg ha^-1, T₁₁ = NPKS+ basal dose with boron and molybdenum @ 2 kg ha^-1 and 2 Kg ha^-1, T₁₂ = NPKS+ basal dose with boron and molybdenum @ 3 kg ha^-1 and 1 kg ha^-1, T₁₃ = NPKS+ basal dose with boron and molybdenum @ 3 kg ha^-1 and 2 kg ha^-1. A total of 117 pots were prepared with 8 kg soils in each. The pots were arranged in 3 sets with 3 pots per set of 13 treatments. Preliminary 3-4 seeds were sown and they were thinned keeping two plants per pot at two leaf stage. The experiment was laid out in completely randomized design (CRD. Data were recorded at 45, 60 and finally at 73 DAS at maturity. At all samplings, data on leaf area, leaf, stem and root dry weights were recorded and at maturity yield and yield components were recorded.

Achievement/Findings:

Boron application either as basal or foliar spray in summer mung did not show statistical significant differences in grain yields but doses of 2 -3 kg ha^-1 had almost similar yield. Similarly its application in mustard also affected very little on grain yield when applied either as basal or in spray in RD of 4 kg ha^-1.
