Abstract/ Executive Summary:

The study was carried out during 2007-2008 season in the research field of Wheat Research Centre, Bangladesh Agricultural Research Institute, Dinajpur to know the effect of lime, Magnesium (Mg) and Boron (B) on yield and yield components of wheat and also their residual effect on mungbean. The geographical position of the area is between 25°62´ N, 88°63´ E and 38.20 meter above sea level. The experiment was laid out in Randomized Complete Block Design with three replications, both in wheat and mungbean. Treatments for wheat were (I) recommended fertilizer + Mg + B, (II) recommended fertilizer + lime + B + Mg, (III) recommended fertilizer + lime + Mg, (IV) recommended fertilizer + lime + B and (V) control (Only recommended fertilizer) and for mungbean were (I) recommended fertilizer + Mg + B, (II) 75% of recommended dose, (III) recommended fertilizer + B, (IV) recommended fertilizer + Mg and (V) control (without fertilizers). Results showed that the highest yield and yield components of wheat were recorded from recommended fertilizers + lime + B + Mg treated plot and the second highest were recorded from recommended fertilizers + lime + Mg treated plot. The lowest was recorded in control plot (only recommended fertilized). In case of mungbean the highest was found from recommended fertilizers + B treated plot, this treatment was limed in previously cultivated wheat crop and the lowest was recorded from control plot (without fertilizer).

Commodity: Wheat

Objectives:

1. The present study has been undertaken to know the effect of lime, Mg and B on yield and yield components of wheat (Triticum aestivum L.) and their residual effect on mungbean (Vigna radiata L.).

Methodology:

Experimental procedures for wheat - The experiment was laid out in Randomized Complete Block Design with 3 replications. For wheat treatments were- (I) recommended fertilizer + Mg + B, (II) recommended fertilizer + lime + B + Mg, (III) recommended fertilizer + lime + Mg, (IV) recommended fertilizer + lime + B and (V) control (Only recommended fertilizer). Unit plot size was 5×4 m. For liming, CaCO₃ was applied in treatment wise at the rate of 2 t ha^–1and irrigation was done immediately after application. Mg and B were applied treatment wise at the rate of 10 and 1 kg ha^–1, respectively. For wheat experiment variety Prodip (BARI Gom-24) was used. Seed was treated with Provax-200 WP an effective seed treating fungicide, consisting of Carboxin and Thiramon. Sowing was done on 04 December 2007 in lines 20 cm apart at a seed rate of 140 kg ha–1. Recommended fertilizer dose for wheat was 120- 35-50-20-4 kg ha–1 N-P-K-S-Zn. Two-third of N and full amount of other fertilizers were applied as basal during final land preparation. Rest 1/3 of N fertilizer was applied after first irrigation on 21 days after sowing (DAS). Second and third irrigations were given at booting (47 DAS) and grain filling (78 DAS) stage. Data on wheat experiment - Data on plants m^–2 (no.), tillers m^–2 (no.), spikes m^–2 (no.), plant height at maturity (cm), spike length (cm), Spikelets spike^–1 (no.), grains spike^–1 (no.), 1000-grain weight (g), straw yield (t ha^–1), grain yield (t ha^–1) and harvest index (%)were recorded. Grain yield was adjusted to 12% moisture. The harvest index (%) was calculated according to the following formula. Harvest index (%) = Grain yield / Biological yield (grain yield + straw yield) ×100. Experimental procedures for mungbean - After harvested of wheat mungbean was grown in the same plots. Treatments for mungbean experiment were- (I) recommended fertilizer + Mg + B, (II) 75% of recommended dose, (III) recommended fertilizer + B, (IV) recommended fertilizer + Mg and (V) control (without fertilizers). According to the research finding (Fatell et al., 2007), it was assumed that the effect of liming would continue at least for the next crop. For this reason liming was not done before mungbean. The recommended dose of fertilizers for mungbean as 20-20-30-10-4 kg ha^–1 N-P-K-SZn. Mg and B were applied treatment wise at the same rate for wheat. All the fertilizers were applied as basal during final land preparation. Variety BARI Mug-6 was sown on 11 April 2008 at a seed rate of 30 kg ha^–1 in lines 30 cm apart. The light irrigation was done just after sowing. Thinning was done on 11 DAS. Weeding was done 24 DAS. Insecticide was applied 2 times. Other intercultural operation was done when necessary. Crop was harvested at full maturity. Data on mungbean: Data on plants m^–2 (no.), plant height at harvest (cm), Fresh weight of plants m^–2 (g), pods plant⁻¹ (no.), pod length (cm), seeds pods⁻¹ (no.), 1000- grain weight (g), biological yield (t ha^–1) and grain yield (t ha^–1) were recorded. Data on soil - Soil pH was measured immediately before liming, and 56 and 70 Days after liming (i.e. 42 and 56 DAS). Soil pH was measured in a 1:2 soil/water using glass electrode pH meter. Organic carbon was determined by Walkley and Black oxidation method , total N was determined by micro Kjeldhal method. Ca and Mg were determined by extractable method, P, K, S and Zn were determined by modified Hunter’s methods. B was determined colorimetrically by the Azomethine- H method. Data analysis - Data were complied and subjected to statistical analysis. Analysis of variance (ANOVA) was done and means separation was done according to Duncan’s New Multiple Range Test

Achievement/Findings:

From the results it is concluded that yield and yield components of wheat were the highest recommended fertilizers + lime + Mg + B treated plot and the second highest were recorded from recommended fertilizers + lime + Mg treated plot. The lowest was recorded in control plot (only recommended fertilized). In case of mungbean the highest was found from recommended fertilizer + B treated plot, which was limed in previously cultivated wheat crop and the lowest was recorded from control plot (without fertilized).
