Abstract/ Executive Summary:

Effect of 4 different row spacing -15, 20, 25 and 30 cm with a constant row spacing of 10 cm and levels of N - 0, 28, 56, 84 and 112 Kg/ha on the performance of Sonora-64 cultivar of wheat was studied. The results indicated that levels of N had significant effect on all the characters studied. Plant population in 20 cm row spacing could not be compensated by better response of other yield contributing characters where wider spacing was adopted. On the other hand at 15 cm row spacing the number of fertile tillers/plant showed a sharp decline. The row spacing of 20 cm with 112 kg/ha nitrogen produced the best yieId.

Keywords: Row spacing, Levels of nitrogen, Wheat

Location: Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh

Start Date: 00-00-1977

End Date: 00-00-1978

Program Area: Crop-Soil-Water Management

Commodity: Wheat

Objectives:

To find out the optimum row spacing and level of N/ha for maximum grain yield of wheat.

Methodology:

An experiment with Sonora-64, a dwarf high yielding Maxican wheat cultivar was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the wheat growing season 1977-78. The average organic matter content, total nitrogen, available N, P₂0₅ and K₂0 as obtained from soil analysis are 0.96, 0.10, 0.002. 0.12 and 0.6%. respectively. The seeds were sown under 15, 20, 25 and 30 cm row to row distant at a constant plant spacing of 10 cm within the rows. with five different levels of N 0, 28, 56, 84 and 112 Kg/ha in addition to 65Kg of P₂0₅ and 55Kg of K₂0 per hectare. The experiment was laid out in a spilt plot design with four replications. The treatments of row spacing were assigned to the main plots and the levels of N to the unit plots (3.0m x 4.5m). The crop was irrigated twice each at the following day of nitrogen top dressing. Three hand weeding were done after 15, 40 and 55 days of seeding. Data on different characters were collected from 20 randomly selected plants/plot and on the entire plot basis. The crop was harvested after 11 2 -11 8 days of sowing.

Achievement/Findings:

The results indicated that levels of N had significant effect on all the characters studied. Plant population in 20 cm row spacing could not be compensated by better response of other yield contributing characters where wider spacing was adopted. On the other hand at 15 cm row spacing the number of fertile tillers/plant showed a sharp decline. The row spacing of 20 cm with 112 kg/ha nitrogen produced the best yield.
