Abstract/ Executive Summary:

An experiment was conducted at the Horticulture Research Farm, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh from November 2015 to March 2016 to find out the effects of potassium on the growth, yield, and Physico-chemical properties of three garden pea (Pisum sativum) varieties. The experiment comprises three Garden pea varieties viz. V₁ = IPSA Motorshuti-3, V₂ = Broad Bean MasterPiece, and V₃ = BARI Motorshuti-1 and four levels of potassium viz. K₀ (Control), K₁ (25 kg ha^-1), K₂ (50 kg ha^-1), and K₃ and (75 kg ha^-1), respectively. The experiment was laid out in a randomized complete block design with three replications. The results of the experiment reviled that K nutrition and genotypic variation significantly (p < 0.05) determined the yield of the garden pea. Different levels of potassium had significant influences on almost all the parameters studied in these three varieties. Maximum plant height (166.67 cm), branches plant^-1 (7.00), pods plant^-1 (39.00), sugar content (15.40%) was obtained from V₁K₂ (IPSA Motorshuti-3 with 50 kg K₂O ha^-1) treatment. Whereas highest pod length (8.533 cm), pod breadth (9.47 mm), number of seeds pod^-1 (8.67), green seed weight (305.00 g), Magnesium content, (0.29%) was obtained under the treatment V₂K₂ (Broad Bean Masterpiece with 50 kg K₂O ha^-1). The maximum green pod yield (12.78 t ha^-1), calcium content (0. 20%), vitamin- A (1.03 mg/kg), was obtained from V₃K₂ (BARI Motorshuti -1 with 50 kg K₂O ha^-1).

Commodity: Potash, Gardenpea

Objectives:

To see the effect of different levels of potassium on the growth, yield, and Physico-chemical properties of three garden pea (pisum sativum) varieties.

Methodology:

The experiment was set up at the Research Farm of Horticulture Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh from November 2015 to March 2016. The experimental site was at 25°39′ N latitude and 88°41′ E longitude with an elevation of 37.58 meters above the sea level. The experimental field was a medium-high having sandy loam soil with pH 6.20. The experiment comprises three garden pea varieties viz. V₁ = IPSA Motorshuti-3, V₂ = Broad Bean Masterpiece, and V₃ = BARI Motorshuti-1 and four levels of potassium viz. K₀ (Control), K₁ (25 kg ha^-1), K₂ (50 kg ha^-1), and K₃ and (75 kg ha^-1), respectively. So the combination of the treatments was V₁K_0, V₁K_1, V₁K_2, V₁K_3, V₂K_0, V₂K₁, V₂K₂, V₂K₃, V₃K₀, V₃K₁, V₃K₂, and V₃K₃, respectively. The experiment was laid out in a randomized complete block design with three replications. Data were collected on different growth, yield, and quality contributing characteristics i.e. plant height (cm), number of primary branches plant^-1, number of flowers plant^-1, number of pods plant^-1, number of seeds pod^-1, pod length (cm), pod breadth (mm),1000 seed weight (g), green pod yield (t ha^-1). Dried Seeds were analyzed chemically for the following: dry matter, calcium, magnesium, potassium, vitamin C, vitamin A, and total sugar content. Finally, the data were analyzed by using MSTAT - C.

Achievement/Findings:

The positive response between variety and potassium application on yield components and the Physico-chemical properties of garden pea was noticed in this study. However, the garden pea genotype V₃ (BARI motorsuti -1) was more responsive to K₂ (50 kg ha^-1) level of potassium in respect of different growth, yield attributing, and Physico-chemical parameters. So it can be concluded that the variety BARI Motorsuti-1 with potassium at the rate of 50 kg ha^–1 is a promising practice for the highest yield of a garden pea.
