Genetic analysis of yield and yield attributing characters of blackgram (Vigna mungo (L.) Hepper) during summer season in gangetic alluvial soil of West Bengal

A field experiment was conducted during rabi (winter) seasons of 2007-08 and 2008-09 to study the effect of integrated nutrient management on growth, yield, oil content and nutrient uptake of yellow sarson (Brassica cam-pestris L var. yellow sarson) in older alluvial soil of West Bengal. Significantly higher leaf area index (1.75 at 40 days after sowing; DAS), dry matter accumulation (1366.9 g/m2 at 80 DAS) and highest number of siliquae/plant (118.3), number of seeds/siliqua (21.8), seed yield (1.90 t/ha), stover yield (3.86 t/ha) were recorded significantly (at 5% lev-el) higher with poultry manure (PM) @2.5t/ha +50%RDF (Recommended Dose of Fertilizer i.e. 80-40-40 of N-P2O5-K2O kg/ha) + PSB (phosphate solubilising bacteria) + AZ (Azotobacter) during both the years and on pooled basis. An average of 30.5% and 233% increase in seed yield by this treatment was recorded over sole application of RDF and control respectively. Integrated application of PM (2.5 t/ha) + 50% RDF + PSB + AZ recorded highest oil content (43.16%) and positive effect on soil fertility status. The highest benefit: cost ratios (2.26 and 2.4 in 2007-'08 and 2008-'09 respectively) were achieved from the use of 50% RDF + PM (2.5 t/ha) +PSB+AZ.

Experimental Region

The field experiment was conducted at District Seed Farm, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal in summer season of 2011 and 2012. Pre-sowing bio-priming was done with Trichoderma viride and Pseudomonas fluorescens with an un-primed control to assess the trend of okra varieties viz., Lalu, Arka Anamika, Ramya, Satsira, Lady Luck,Debpusa Jhar,Japani Jhar and Barsha Laxmi due to bio-priming of seeds towards vegetable production Significant variation among the varieties was noted for all the characters studied. Okra variety Lalu gave highest vegetable yield per plant in both years and it was statistically at par with Arka Anamika. Vegetable yield per plant was increased by 4.33 to 20.08% in first year and 3.68 to 19.60% in second year with T. viride as compared to P. fluorescens and un-primed control. Individual varieties indicated that vegetable yield per plant was maximum with Lalu when priming was made with both the bio-inoculants followed by Arka Anamika during both years. Hence, Lalu and Arka Anamika may be recommended for experimental region for higher yield and pre-sowing seed bio-priming may be recommended with both T.viride and P. fluorescens for enhanced vegetable yield of okra.
