Abstract
To examine the effect of variety and different level of potassium (K) on yield of jute, an experiment was conducted at the Agronomy Field Laboratory, Patuakhali Science and Technology University, Dumki, Patuakhali from May to September 2016 using three variety viz. C-2197, C-3069 and C-3473. There are four levels of K viz. 0, 35, 45 and 55 kg ha-1. The land was fertilized as per treatment specifications from muriate of potash along with recommended doses of urea, TSP, gypsum and zinc sulphate. The experiment was laid out in randomized complete block design (RCBD) with three replications. The variety O-3069 had significant influence on number of internodes per plant (64.20), plant diameter (21.15mm), fiber weight per plant (25.92g), fiber yield (5.18t ha-1), stick weight per plant (64.75g) and stick yield (12.94t ha-1). The highest results of plant height (3.81m) and green weight with leaf (4.04kg/10 plant) were obtain from C-3473 and green weight without leaf (3.54 kg/10 plant) were obtained from C-2197. Among the different potassium levels 55kg K ha-1 had significant influence on number of internodes per plant (70.13), plant diameter (22.60mm), green weight with leaves (4.43kg/10 plant) and green weight without leaves (3.91kg/10 plant), fiber weight per plant (27.93g), fiber yield (5.59t ha-1), stick weight per plant (69.60g) and stick yield (13.90t ha-1). The highest plant height (4.13m) were obtained from 35 kg K ha-1. The variety O-3069 with 55kg K ha-1 had significant influence on plant diameter (24.00mm), fiber weight per plant (31g), fiber yield (6.2t ha-1), stick weight per plant (77.53g) and stick yield (15.50t ha-1). The highest results of plant height (4.30m), number of internodes per plant (73), green weight with leaf (4.85kg/10 plant) and green weight without leaf (4.25kg/10 plant were obtain from C-3473 with 55kg K ha-1. The results of the present experiment showed that the C-3069 was the best among the varieties. On the other hand, 55kg k ha-1 was proved to be better than any other lower and higher levels of potassium. Therefore, it can be inferred that jute can produce the highest fibre yield from a combination of variety C-3069 with 55kg k ha-1 in field under the coastal region of Bangladesh.

Jute (Corchorus capsularis) is an important foreign exchange earning commercial golden fibre crop of Bangladesh
Jute is the second important fibre crop of the world and it is generally known as golden fibre of Bangladesh as it contributed as lion share to the economy
Observation of the present study, it may be concluded that the variety C-3069 and 55kg K ha–1 as singly or their interaction were more successful for remarkable production of jute
Summary
Jute (Corchorus capsularis) is an important foreign exchange earning commercial golden fibre crop of Bangladesh. Jute is the second important fibre crop of the world and it is generally known as golden fibre of Bangladesh as it contributed as lion share to the economy. It is grown in Bangladesh, India, Myanmar, Nepal, China, Taiwan, Thailand, Vietnam, Cambodia, Brazil and some other countries. In Bangladesh, the area of Jute cultivation is 7, 08,723 hectares of land where the total production is 83, 95,840 bales per annum with an average yield of 4.79 bales per acre (11.846 bales per hectare) which was found by the statistical report of 2010-11 [2]. Yield per hectare has decreased from 2.39 t ha-1 in 2010-2011 to 2.00 t ha-1 in 2012-2013. [7]
