Abstract/ Executive Summary:

The experiment was conducted at the Regional Agricultural Research Station, Ishurdi, Pabna during rabi season, 2012-2013 to find out the superior variety/lines under zero tillage mulched cultivation. Seven garlic varieties/lines viz., BARI Roshun-1, BARI Roshun-2, GC0018, GC0024, GC0027 and GC0034 and one local cultivar were used in the experiment. Garlic line GC0034 produced the highest bulb yield (13.40 t/ha) having higher individual bulb weight, number of leaves/plant, number of clove/bulb, 100-clove weight and neck diameter. The line GC0027 showed the highest plant height and bulb diameter.

Keywords: Performance, Garlic varieties, Zero tillage, Mulched condition

Location: RARS, Ishurdi, Pabna

Start Date: 11-11-2012

End Date: 01-04-2013

Program Area: Crop-Soil-Water Management

Commodity: Garlic

Objectives:

To find out the superior variety/lines under zero tillage mulched cultivation.

Methodology:

The experiment was conducted at the Regional Agricultural Research Station, Ishurdi, Pabna during rabi season, 2012-2013 to find out the superior variety/lines under zero tillage mulched cultivation. The land was medium high and the soil was clay loam in texture. The experiment was laid out in a RCB design with three replications. Seven garlic genotypes namely BARI Roshun-1, BARI Roshun-2, GC0018, GC0024, GC0027, GC0034 and one local cultivar were evaluated. The unit plot size was 2m x 1.20m. The initial soil moisture was 40.14%. The crop was planted in line, maintaining 15 cm x 10 cm plant spacing. The crop was fertilized with 155-35-125-30-2-1 kg N-P-K-S-Zn-B/ha. One third nitrogen and all other fertilizers were applied on the muddy soil as basal before planting and two third nitrogen was top dressed in two equal installments at 25 and 50 days after planting. Two weeding was done at 25 and 50 days after emergence. The crop was planted on 11 November 2012 and harvested on 1 April, 2013. The changes of soil moisture level at different days after emergence are depicted in Fig. 1. Data on yield and yield components were recorded and analyzed statistically. The mean values were adjusted by LSD at 0.05 levels of probability.

Achievement/Findings:

Garlic line GC0034 produced the highest bulb yield (13.40 t/ha) having higher individual bulb weight, number of leaves/plant, number of clove/bulb, 100-clove weight and neck diameter.The line GC0027 showed the highest plant height and bulb diameter.Garlic lines GC0018, GC0027 and GC0034 performed better under zero tillage mulched condition compared to BARI Roshun-1, BARI Roshun-2, GC0024 and one local cultivar. Among them GC0034 gave the highest bulb yield.
