Abstract/ Executive Summary:

An experiment was conducted at the Bangladesh Agricultural University. Mymensingh during November 1976 to March 1977 with three weeding treatments such as no weeding; one hand weeding. three weeks after seeding; two hand weedings. three and six weeks after seeding; and 9 different dates of sowing at an interval of 5 days from 5 November to 15 December. Weeding and the interaction of weeding and date of sowing had no significant effect on any of the characters studied. The date of Sowing significantly influenced all the characters studied except the plant height and 1000-grain weight. November 15 sowing appeared to be the optimum time for getting highest yield.

Keywords: Weeding, Sowing, Yield, Lentil

Location: Bangladesh Agricultural University, Mymensingh

Start Date: 00-11-1976

End Date: 00-03-1977

Program Area: Crop-Soil-Water Management

Commodity: Lentil

Objectives:

To see the effect of weeding and date of sowing on the yield of lentil.

Methodology:

The experiment was conducted at the Bangladesh Agricultural University, Mymensingh during November 1976 to March 1977. Three weeding treatments such as no weeding (control); one hand weeding, three weeks after seeding; two hand weedings, three and six weeks after seeding; and nine dates of sowing 5, 10, 15, 20, 25 and 30 November and 5, 10 and 15 December were included in the study. The experiment was laid out in a split plot design with three replications. The weeding treatments were placed in the main plots while the dates of sowing were in the sub plots measuring 2.44 sq. m. each. Seed stocks were collected from four districts of Bangladesh namely, Bogra, Mymensingh, Chittagong and Pabna (Mian, 1976). Prior to seeding, the seed samples of each district were tested for their germination percentage. The tested seed stocks were mixed thoroughIy and broadcast in the field at the rate of 18,46 kg per hectare. A basal dose of 20-18-20 kg/ha of N, P₂0₅ and K₂0 respectively was applied through urea, triple superphosphate and muriate of potash, Weeding was done with Niranee, an indigenous hand implement. The whole plot was harvested between 26 February to March 1977 by cutting plants with sickle close to the ground for yield. Observations were made on the plant height at harvest and yield components from 10 randomly selected plants uprooted from each plot. The 1000 grain weight was determined from the sun-dried grains of each unit plot. The collected data were analysed statistically and the means were compared by Duncan's New Multiple Range Test.

Achievement/Findings:

Weeding and the interaction of weeding and date of sowing had no significant effect on any of the characters studied. The date of sowing significantly influenced all the characters studied except the plant height and 1000-grain weight. November 15 sowing appeared to be the optimum time for getting highest yield.
