Abstract/ Executive Summary:

The experiment was carried out at Agronomy Field laboratory, Department of Agronomy and Agricultural Extension, university of Rajshahi, to study the effect of irrigation and sowing method on yield and yield attributes of mustard. The experiment consists of two factors i) irrigation viz. no irrigation (I₀), one irrigation (I₁) and two irrigations (I₂) ii) sowing method viz. line sowing method (M₁) and broadcasting method (M₂). A split- plot design was used for the experiment by assigning the irrigation on the main plots and sowing method to the sub plots with three replications. Irrigation had significant effect on all the yield and yield contributing characters. The highest plant height, number of branches plant^-1, filled siliqua plant^-1, sliqua length, number of seed siliqua^-1, 1000-seed weight and stover yield were obtained from I₂ (two irrigations) and consequently it produced the highest seed yield. Sowing method also had significant influence on almost all the yield and yield contributing characters. All the yield contributing characters except number of unfilled siliqua plant^-1 were found best at line sowing method (M₁) and consequently it produced the highest seed yield. However it could be noted from the study that the combination of two irrigations with line sowing method is better to get higher yield of mustard.

Start Date: 00-11-2010

End Date: 00-02-2011

Program Area: Crop-Soil-Water Management

Commodity: Mustard

Objectives:

To find out the effect of irrigation and sowing method on the yield and yield attributes of mustard.

Methodology:

The experiment was conducted at the Agronomy Field Laboratory, Department of Agronomy and Agricultural Extension, Rajshahi University, Rajshahi, during the period from November, 2010 to February, 2011 to study the effect of irrigation and sowing method on yield and yield attributes of mustard. The field belongs to the High Ganges River Flood Plain soils of AEZ-11. The soil was sandy loam. The soil of the experimental plot contained pH 7.56, total nitrogen (%) 0.084, available P (ppm) 11.25, available K (ppm) 35.54, available S (ppm) 24.36, available Zn (ppm) 35.24 and available B (ppm) 25.45. The experiment was designed with two factors. Factor (A) Levels of irrigation viz (i) No irrigation (I₀) ii. One irrigation (I₁) (25 days after sowing) and (iii). Two irrigation (I₂) (One at 25 DAS and other at 50 DAS) and factor B. Sowing method viz (i) Line sowing (M₁) and ii. Broadcasting (M₂). Split plot design was used for the experiment by assigning the irrigation in the main plots and sowing method in the sub plots. The treatments were replicated three times. The size of each plot was 2 m×2 m. BARI sarisha-13 was used as experimental material. The land was opened by a power tiller, later on it was ploughed and cross ploughed with country plough followed by laddering. The first ploughing was done 24 October 2010 and final land preparation was done on 5 November 2010 respectively. The experimental land was fertilized with urea, TSP, MoP, Gypsum and Borax fertilizers @ 250, 180, 100, 150 and 10 kg ha^-1 respectively. The whole amount of TSP, MoP, Gypsum and Borax were applied as basal dose at final land preparation. Urea was applied in three equal splits, 1/3 as basal, 1/3 at 25 DAS and the rest 1/3 at 50 DAS. The seeds were sown on 9 November 2010. Two weedings cum thinning were done. Irrigations were done as per experimental treatments. The crop was harvested at the 90% of the siliqua maturity on 24 February 2011 at 102 DAS. Before harvesting the whole plot, 10 plants were randomly selected from each plot for collecting data on yield attributes. The sample plants were uprooted prior to harvest and dried properly in the sun and collected data from these plants. The seed and stover yields were measured from the plot after harvesting, cleaning and drying the plants from the whole plot. Data recorded were compiled and tabulated in proper form for statistical analysis. Analysis of variance was done with the help of computer package MSTAT-C. The mean differences were compared with Duncan’s Multiple Range Test (Gomez & Gomez, 1984).
