Abstract/ Executive Summary:

A field experiment was conducted at the Pulse Research Sub-station of Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during the rabi season of 2015-16 to evaluate the effect of growth and yield parameters 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 fertilizer combinations on the plant growth parameters was not significant but yield characters varied significantly. The higher seed yield was produced in the treatment FRG 2012 (1105kg/ha),75% FRG +25% CD(1101 kg/ha) and 75% FRG + 25% PM (1098 kg/ha).

Keywords: Pulses, Lentil, Grain yield, Soil, Nutrient

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

Start Date: 00-00-2015

End Date: 00-00-2016

Program Area: Crop-Soil-Water Management

Commodity: Lentil

Objectives:

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

Methodology:

The field experiment was conducted at the research farm of Pulse Research sub-station, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during the rabi season of 2015-16. The soil characteristics of the area is 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 the soil of the experimental field are presented in table 45. The nutrient status of cowdung and poultry manure applied in the experimental plots are shown in Table 46. From initial soil test results, the higher values of phosphorus, sulphur, zinc and boron were observed at Gazipur. 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, T_{5 =}50% FRG + 50% PM and T_{6 =}Control. The experiment was laid out in a 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 11 November, 2015 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 20 February, 2016. Data on growth characteristics and yield parameters were recorded and analyzed statistically.

Achievement/Findings:

The effect of inorganic fertilizers in combination with cowdung and poultry manure influenced the growth and yield of lentil. The highest seed yield of lentil 1105 kgha^-1 was produce from FRG 2012, followed by 1101 kg ha^-1 (75% FRG + 25% CD) and 1098 kg ha^-1 (75% FRG + 25% PM) respectively. However, this is the first year trial. The experiment will be continued in the next year for confirmation.
