Abstract/ Executive Summary:

Effect of plant density and fertilizer rate on the performance of short duration mustard cv. BARI Sarisha-14 was investigated with an experiment from October, 2015 to June, 2016 at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh.The experiment was laid out in split plot design with three replications. The experiment consisted of four plant densities: P1: 56 plants/m² (30 cm × 6 cm), P2: 67 plants/m²(25 cm × 6 cm), P3: 80 plants/m² (25 cm × 5 cm), P4: 100 plants/m²(25 cm × 4 cm) and four rates of fertilizer: F0: Control (no fertilizer) F1: 100% of fertilizer recommended rate (Fertilizer Recommendation Guide-2012), F2: 120% of fertilizer recommended rate F3: 140% of fertilizer recommended rate. The highest seed yield was obtained (1.60 t/ha) in plant density P2: 67 plants/m² (25 cm × 6 cm) with the combination of high rates of fertilizer F3: 140% of recommended fertilizer rate. The next best result was (1.50 t/ha) recorded in case of plant density P1:56 plants/m² (30 cm × 6 cm) with the combination of fertilizer rate F3: 140% of recommended fertilizer rate. It indicated, high plant density with combination of recommended fertilizer reduce yield. It is concluded from the study that of BARI Sarisha-14 in combination with plant density (25 cm x 6 cm) and high rates of fertilizer produced highest seed yield at agro-climatic condition of Mymensingh.

End Date: 17-01-2016

Program Area: Crop-Soil-Water Management

Commodity: Mustard

Objectives:

The present study is undertaken to assess the effect of plant density and fertilizer rate on the performance of recently released mustard cultivar BARI Sarisha-14.

Methodology:

The experiment was conducted at the Agronomy Field Laboratory of the Department of Agronomy, Bangladesh Agricultural University (BAU), Mymensingh, during the period from 2 October, 2015 to 17 January, 2016. The experimental site was a medium high land with well drained clay loam textured soil having 6.9 pH value.The site is located on the sub-tropical zone where temperature is moderately low and plenty of sunshine during Rabi season. BARI Sarisha-14, a new high yielding short duration variety under cruciferae family was used as test crop. Four plant densities viz., 56 plants/m² (30 cm× 6 cm), 67 plants/m² (25 cm × 6 cm), 80 plants/m² (25 cm × 5 cm), 100 plants/m² (25 cm × 4 cm) and four rates of fertilizer viz., Control (no fertilizer), 100% of recommended fertilizer rate (Fertilizer Recommendation Guide-2012) i.e; Urea = 200 kg/ha, TSP = 130 kg/ha, MoP= 120 kg/ha, Gypsum= 80 kg/ha), 120% of recommended fertilizer rate, 140% of recommended fertilizer rate were used in the experiment. The experiment was laid out in two factor split plot design with three replications. The unit plot size was 1.6m x 1.25m. Half of urea and full doses of TSP, MP and gypsum were applied as basal dose during final land preparation. Remaining half urea was applied as top dressing at the time of flower initiation stage (25 days after sowing). Hand weeding was done two times at 15 and 30 DAS. Thinning was done in all unit plots with care to maintain a constant plant population in each row. The crop was grown with all other agronomic managements as and when necessary. For the convenience of collecting data, five sample plants/plot were selected at random. The sample plants were uprooted prior to harvest and dried properly in the sun before collecting data. The seed and straw yield/plot were recorded after cleaning and drying them properly in the sun. All the collected data were analyzed with package MSTAT (Russel and Freed, 1986). The mean differences among the treatments were tested with Duncan’s Multiple Range Test (Gomez and Gomez, 1984).

Achievement/Findings:

Plant density P2 = 67 plants/m² (25 cm x 6 cm) and 140% of recommended rates of fertilizer were best for BARI Sarisha-14 for highest yield and it should be tested at different Agro-ecological Zones of the country.
