Abstract/ Executive Summary:

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from July to December 1998 to evaluate the effect of different propagating materials and levels of phosphorus fertilization on the yield and quality of Sesbania rostrata seed. The experiment consisted of four propagating materials viz., top portion, middle portion, base portion and seedling of Sesbania rostrata plant; and five levels of phosphorus viz., 0 (control), 20, 40, 60 and 80 kg P20s ha•'. The experiment was laid out in a randomized complete block design with four replications. Results showed that among the different propagating materials, top portion of the plant gave the highest seed yield (1.54 t ha•') and highest germination percentage (33.00). Plant biomass, seed yield and seed germination percentage were highest with the highest phosphorus level up to 80 kg ha•'. Top cutting coupled with 80 kg PzOs ha•' produced the highest plant biomass (5.09 t ha'') and seed yield (1.76 t ha^-1).

Keywords: .Planting materials, Phosphorus levels, Yield, Quality, Sesbania rostrata seed

Location: At the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh

Start Date: 00-07-1998

End Date: 00-12-1998

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

To see the effect of different planting materials and levels of phosphorus fertilization on the yield and quality of Sesbania rostrata seed.

Methodology:

The experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during the period from July to December 1998. The experiment consisted of four propagating materials viz., top portion, middle portion and base portion of the mother plant and seedling of Sesbania rostrata; and five levels of fertilizer viz., 0 (control), 20, 40, 60 and 80 kg P20 ha•1 . The experiment was laid out in a randomized complete block design with four replications. The size of unit plot was 4 m x 2.5 m and the number of total plot was 80. The main plot was made ready for transplanting/planting by subsequent ploughing and laddering by country plough. The whole amount of P205 in the form of triple super phosphate was applied as basal dose and mixed with soil by spading. Sesbania rostrata plants were collected from the Agronomy Field Laboratory of Bangladesh Agricultural University. The whole plant was cut into three pieces i.e., top, middle and base portions. Length of each cutting was 50 em. Slanting cut was given to the cuttings with a sharp knife. Cuttings were planted in the main field on 20 August 1998 at an angle about 40 to 50 degree. Thirty-day-old seedlings were transplanted on 30 August 1998. The cutting and seedlings were planted at a spacing of 50 em x 25 em.
