Abstract/ Executive Summary:

Application of the optimum dose of the combination of Rhizobium inoculation (RI) and phosphorus (P) fertilizer could be an important factor to get maximum yield in soybean. The experiment was conducted at Noakhali Science and Technology University Field Laboratory to examine the effect of different combine doses of RI and P on nodulation, growth, and yield of Binasoybean-1. Four levels of RI (0, 25, 50, 75 g kg^-1 seed i.e. I₀, I₁, I₂, I₃) and P (0, 18, 36, and 54 kg P ha^-1 i.e. P₀, P₁, P₂, P₃) were applied. Plant height and no. of nodule plant^-1 showed significant interaction effect between different levels of RI and P at all sampling dates. Dry weight plant^-1 showed significant at 60 and 75 days after sowing (DAS) whereas insignificant results showed at 45 DAS. The highest plant height, no. of nodule plant^-1 and dry weight plant^-1 were observed in 75 DAS with the combinations of RI and P rates at I1P0 (25 g kg^-1 seed and 0 kg P ha^-1 ), I₁P₁ (25 g kg^-1 seed and 18 kg P ha^-1 ) and I3P1 (75 g kg^-1 seed and 25 kg P ha^-1 ) respectively. The interaction effect between the different levels of RI and P with the no. of pods plant^-1, no. of effective pods plant^-1 no. of seed pod^-1 and 1000 seed weight were statistically significant, whereas insignificant relation with the no. of non-effective pods plant^-1 and pod length. Besides, total node number and plant dry weight without seed at harvest stage showed a highly significant positive correlation with seed yield, indicating higher vegetative growth increase seed yield of soybean. Among sixteen treatment combinations, the highest seed yield (2.297 t ha^-1 ) was obtained from the treatment combination of I2P3 (50 g kg^-1 seed and 54 kg P ha^-1 ) and it may be suggested as a proper dose of RI and P for Binasoybean-1.

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer, Soybean

Objectives:

To examine the combined effect of RI and P on nodulation, growth and yield of soybean.

Methodology:

The experiment was carried out at Noakhali Science and Technology University field laboratory during the period from 15^th January to the 1^st week of May 2018. The area lies between 10 m above sea level and latitude 22.790 with loamy soil, medium-high land. The area was characterized by a sub-tropical climate. And, average temperature and rainfall were 27.5ºC and 33.125 mm respectively during the experimental time (WMN 2018). Experimental setup- The Binasoybean-1 seed was sown on 15 January 2018. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. There were 48 plots having the size of each plot was 2.5 m × 4 m. Four levels of RI (0, 25, 50, 75 g kg^-1 seed i.e. I₀, I₁, I₂, I₃) and P (0, 18, 36, and 54 kg P ha^-1 i.e., P₀, P₁, P₂, P₃) were applied as a treatment. Chemical fertilizer was applied as basal at a rate of urea: M_OP: Gypsum: Boric acid = 55:110:100: 10 kg ha^-1. Weeding was done 20-25 days after emergence and pesticide and water were applied as when as necessary. Measurement and data collection: Plant height (cm), number of nodules plant^-1 (the whole plant uprooted softly, then visible nodules were counted), dry weight (gm) were measured at 45, 60 and 75 days after sowing for 5 plants which was randomly selected from each plot. Besides, number of pods plant^-1, number of effective pods plant^-1, number of non-effective pods plant, pod length (cm), number of seeds pod^-1, the weight of 1000 seeds (gm), total node number at harvest stage, plant dry weight without seed at harvest stage (gm), yield (t ha^-1 ) for 5 plants which was randomly selected from each plot. Statistical Analysis- Analysis of variance was done with the help of the MSTAT-C computer package programme, developed by Russel (1986). The mean differences among the treatments were adjudged by the DMRT test (Gomez and Gomez, 1984). Additionally, the Pearson correlation coefficients with significant level were measured by using data analysis tool of Microsoft Excel (Version 2016).

Achievement/Findings:

Results revealed that the use of RI at 50 g kg^-1 seed in combination with 54 kg ha^-1 P appeared as the best practice for producing the highest grain yield of Binasoybean^-1. This conclusion has been made based on the place of the study, yield may vary in another place due to different fertility status of soil in Bangladeshi.
