Abstract/ Executive Summary:

The study was conducted with the objective to determine the optimum time of sowing of niger for maximum seed yield. The experiment was conducted during the period from October to March. 1986-87 at Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. A promising selection of niger (Nig-1) was used in the experiment. The experiment was laid out in randomized complete block design with three replications. The results revealed a significant variations in plant height, number of branches/plant, number of heads/plant, number of seeds/head, days to flower, days to maturity, 1000- seed weight, and seed yield From the results, it may be concluded that niger should be planted in the first week of November for profitable production.

Keywords: Niger, Yield, Components

Location: Bangladesh Agricultural Research Institute, Joydebpur, Gazipur

Start Date: 01-10-1986

End Date: 30-03-1987

Program Area: Crop-Soil-Water Management

Commodity: Niger

Objectives:

To determine the optimum time of sowing of niger for maximum seed yield.

Methodology:

The experiment was conducted during the period from October to March. 1986-87 at Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. A promising selection of niger (Nig-1) was used in the experiment. The experiment was laid out in randomized complete block design with three replications. The crop was sown in 5 different dates from November 1, to December 31. The experimental area was dressed with 75, 120, 46 kg/ha of N, P₂0₅, and K₂O respectively at land preparation. Seeds were sown by maintaining 25 cm rows at the rate of 9 Kg/ha. Weeding and thinning were done in the third week after sowing. Observations were made on different plant characters. Above ground dry matter was determined on oven dry basis. Data were collected on plant height, number of primary branches/ plant, number of heads/plant, number of seeds/head, dry plant weight, dry seed weight and seed yield/plot. Data analysed.
