Abstract/ Executive Summary:

Farmers are mostly face problem in the context of their cultivation to select right variety with proper levels of fertilizer especially phosphorus for better yield of French bean (legume crops). An experiment was conducted in the field of Fulgach village under Lamonirhat district at the northern region of Bangladesh during November 2014 to February 2015 to assess the effect of phosphorus levels on the growth, yield attributes and yield of French bean (Phaseolus vulgaris L.) varieties. The experiment was conducted maintaining randomized complete block design consisting three French bean varieties, viz. V₁ - BARI Jhar Sheem-1, V₂ - BARI Jhar Sheem-2 and V₃ - Nick and four levels of phosphorus viz. P₀, P₂₀, P₄₀ and P₆₀ kg phosphorus ha^-1, respectively replicated thrice. Varieties showed significant results on growth and yield attributes except number of branches plant^-1 but phosphorus exhibited significant results of all growth and yield attributes except number of seeds pod^-1. Varieties combined with phosphorus given significant results of all the parameters. Highest pod yield (22.70 t ha^-1) was obtained from BARI Jhar Sheem-2 while lowest (16.64 t ha^-1) from BARI Jhar Sheem-1. Highest dose of phosphorus @ 60 kg ha^{- 1} gave highest pod yield (22.12 t ha^-1), where as lowest (18.82 t ha^-1) was obtained in control. Apparently, the highest value of pod yield (24.40 t ha^-1) was found from the combination of BARI Jhar Sheem-2 with 60 kg ha^-1 phosphorus and lowest (15.23 t ha^-1) from the combination of BARI Jhar Sheem-1 with control treatment.

Commodity: French bean, Fertilizer

Objectives:

The study was undertaken to evaluate the influence of phosphorus levels on the growth, yield attributes and yield of French bean varieties.

Methodology:

The research work was conducted in the field of Fulgach village under Lalmonirhat district at the northern region of Bangladesh during November 2014 to February 2015 to evaluate the proper level of phosphorus on growth, yield components and yield of French bean varieties. The initial soil having pH - 5.85, organic matter - 1.29%, nitrogen - 0.07%, phosphorus - 18.35 ppm, potassium - 0.24 mg 100 g^-1 of soil, respectively. The experiment was conducted in the randomized complete block design (RCBD) with three replications. Treatments consisted with three varieties namely, V₁ - BARI Jhar Sheem-1, V₂ - BARI Jhar Sheem-2 and V₃- Nick (released by Lal Teer Seed Limited) of French bean and four levels i.e. P₀ - Control, P₂₀ - 20 (45.8 kg P₂O₅ ha^-1), P₄₀ - 40 (91.6 kg P₂O₅ ha^-1), P₆₀ - 60 kg phosphorus ha^-1 (137.4 kg P₂O₅ ha^-1) of phosphorus, respectively. Two seeds were sown at each hill on 12 November 2014 maintaining at a spacing of 30 cm × 20 cm row to row and hill to hill, respectively. Manures (Cowdung @ 10 t ha^-1) and fertilizers like urea, potassium and dolomite @ 120 : 60 : 1235 kg ha^-1 Were applied as per the treatments. Entire amount of cowdung, dolomite, phosphorus, half of urea and potassium were applied during final land preparation. The rest half of nitrogen and potassium were applied in two equal splits after 20 and 35 DAS (days after sowing) of seeds. In general, market grade boron and zinc were applied as foliar spray @ 1g litre^-1 of water at 20 and 40 DAS. Plots were kept weed free and crop received three irrigation during crop period. Pods were harvested at tender stage through hand pickings and weighed to estimate the yield of fresh pods. Plant height, number of branches plant^-1, pod length, pod breadth, number of pods plan^t-1, number of tender seeds pod^-1, pod weight plant^-1 and pod yield were recorded from randomly selected five plants for growth parameters and ten plants for yield estimation avoiding border effect. Collected data on various parameters were analyzed by MSTATC statistical package program. The analysis of variance for the characteristics under study was performed by F- variance test and difference between the pairs of treatment means was compared using the Least Significant Difference (LSD) test (Gomez and Gomez, 1984). The meteorological data of the experimental site revealed that the maximum (25.61⁰C) and minimum temperature (14.34⁰C) and the crop received 50.1 mm rain showers during November to February.

Achievement/Findings:

From the results and discussions it can be concluded that 60 kg ha^-1 phosphorus showed significant impacts on the growth, yield attributes and yield of French bean. BARI Jhar Sheem-2 gave better production than those of BARI Jhar Sheem-1 and Nick varieties. Whereas 60 kg ha^-1 phosphorus combined with BARI Jhar Sheem-2 gave higher yield in the active Tista flood plain of Bangladesh.
