Abstract/ Executive Summary:

An experiment was conducted at Regional Spices Research Centre, BARI, Magura during April, 2010 to January, 2011 to determine the optimum dose of sulphur and zinc for increasing yield potentiality of turmeric. The highest yield (48.11 t/ha) was recorded with the combined use of sulphur @ 30ks/ha and zinc 3.0 kg/ha along with a constant level of N, P and K @ N100 P40 K90 kg/ha which was significantly different from other treatments. The agronomical data showed that the tallest plant (151.86 cm) and maximum number of (44.53) leaves were found in the treatment S3T2. Other yield components namely number and weight of primary finger rhizome were significantly higher in the same treatment.

Location: Regional Spices Research Centre, BARI, Magura

Start Date: 00-04-2010

End Date: 00-01-2011

Program Area: Crop-Soil-Water Management

Commodity: Turmeric

Objectives:

To study the effect of sulphur and zinc for turmeric production.

Methodology:

An experiment was carried out at Regional Species Research Centre, BARI, Magura during April, 2010 to January, 2011. The experiment was laid out in Randomized complete Blook Design with three replications. The treatment was consisted of four levels of sulphur (O, 10, 20 and 30kg/ha) and four levels of zinc (O, 1.5, 3.0 and 4.5 kg/ha). The land was prepared with good tilth. The unit plot size was 4.8 m ×3.0 m having the plant spacing 60cm×30 cm. BARI Holud-3 was taken as test variety. The crop was planted on 3 April, 2010. Advanced production technologies were followed during the whole crop period. The crop was harvested at maturity on 6 March, 2011. Data on plant height, number of leaves, number of tillers, number and weight of mother rhizome and primary finger, yield per clump and yield per hectare were recorded and analyzed.

Achievement/Findings:

All yield components and yield of turmeric remarkably varied with the single effect of sulphur and zinc. The highest turmeric yield (45.33 t/ha) was produced with the application of 30kg/ha of sulphur and 3.0 kg/ha of Zn. The agronomical data showed that the tallest plant (151.86 cm) and maximum number of (44.53) leaves were found in the treatment S3T2. Other yield components namely number and weight of primary finger rhizome were significantly higher in the same treatment. On the other hand, clump was also recorded in treatment S3T2 and the lowest yield 913.23 gm per clump was found in S0T0. The highest yield (48.11t/ha) of fresh turmeric was obtained with the application rate of 30 kg S/ha and 3.0kg Zinc/ha, along with soil test based. N, P and K application. Application of Sulphur at high application rate i.e. 30 kg/ha and medium dose of Zinc 3.0 kg/ha maximized the yield potentiality of turmeric.The results reveal that yield of turmeric increases at the highest application rate of sulphur and with medium dose of zinc
