Abstract/ Executive Summary:

A field experiment was conducted at the Pulse Research Sub-station of Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during rabi season of 2016-17 to evaluate the effect of growth and yield of lentil with organic and inorganic nutrients and to determine the optimum rate of nutrients of lentil. Five different combinations of nutrients viz. FRG 2012, 75% FRG + 25% CD, 50% FRG + 50 % CD, 75% FRG + 25% PM, 50% FRG + 50% PM were included in the study with one control (Native fertility). The effect of nutrient combinations on the plant growth parameters was not significant but yield characters varied significantly. The higher seed yield was produced (2016-2017) in the treatment 75% FRG +25% PM (935 kg/ha^-1) . Average of two years the heights seed also produced in treatment T₄ = 75% FRG +25% PM (1017 kg ha^-1). It may be concluded that 75% of the recommended doses of inorganic nutrients and 25% of organic sources of nutrients from poultry manure is the best treatment combination to produce lentil in the grey Terrace Soil (AEZ 28) of Gazipur.

Location: Pulse Research sub-station, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, Bangladesh

Start Date: 00-00-2016

End Date: 00-00-2017

Program Area: Crop-Soil-Water Management

Commodity: Lentil, Soil fertility

Objectives:

To determine the optimum dose of nutrients to achieve higher yield of lentil.

Methodology:

The field experiment was conducted at research farm of Pulse Research sub-station, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during rabi season of 2015-16 and 2016-17. The soil characteristics of the area are the Grey Terrace Soil (AEZ 28). The initial soil samples collected from the experimental plot from a depth of 0-15 cm and were analyzed in the laboratory following standard methods. Initial values of some important chemical parameters of soil of the experimental field are presented in table 1.Nutrient status of cowdung and poultry manure applied in the experimental plots. The trial consisted of six nutrient treatments such as T₁= FRG 2012, T₂= 75% FRG + 25% CD, T₃= 50% FRG + 50 % CD, T₄= 75% FRG + 25% PM, T₅= 50% FRG + 50% PM and T₆= Control. The experiment was laid out in Randomized Complete Block design with 3 replications. The unit plot size was 4m×3m. Nutrients N-P-K-S-Zn-B were supplied from Urea, TSP, MP, Gypsum, Zinc sulphate and Boric acid, respectively. All the fertilizers were applied during the final land preparation. The variety was BARI Masur-7. Seeds were sown on the 18 November, 2016 at a rate of 30 kg ha^-1 continuous in line at a depth of 2 to 3 cm below the soil surface. One irrigation was applied immediately after seed sowing. Intercultural operations such as thinning, weeding, applying insecticides were done as and when necessary. The mature plants of lentil were harvested on 3^rd March, 2017. Data on growth characteristics and yield parameters were recorded and analyzed statistically.

Achievement/Findings:

The effect of fertilizers in combination with cowdung and poultry manure influenced the growth and yield of lentil. The higher yield was produced from, 75% FRG + 25% PM. Average of two years treatment T₄(produced the highest seed yield 1017 kg/ha^-1 followed the treatment T₃ (987 kg/ha^-1)and T₄ (927 kg/ha^-1). It may be concluded that 75% of the recommended doses of inorganic nutrients and 25% of organic sources of nutrients from poultry manure is the best treatment combination to produce lentil in the grey Terrace Soil (AEZ 28) of Gazipur.
