Abstract/ Executive Summary:

A field experiment was conducted at Spices Research Centre, Shibgonj, Bogra during December,2008 to March, 2009 to determine the requirement of N, P, K and S of coriander (BARI Dhonia-1) for achieving satisfactory seed yield of this crop. Different levels of nitrogen (0, 40, 70 & 100 kg/ha), phosphorus (0, 25, 50 & 70 kg/ha), potassium (0, 30, 60 & 90 kg/ha) and sulphur (0, 10, 20 & 30 kg/ha) were distributed in the plots. There was a positive impact of those nutrients, on the yield and yield contributing characters of coriander up to a moderate level of N70P50K30S20 kg/ha. The highest seed yield (2.06 t/ha) was obtained with this moderate application of N, P, K, and S (70, 50, 30 &20 kg/ha, respectively) and yield was declined with higher doses of these elements.

Start Date: 22-12-2007

End Date: 10-03-2008

Program Area: Crop-Soil-Water Management

Commodity: Coriander

Objectives:

To evaluate the effect of different levels of nitrogen, phosphorus, potassium and sulfur on the yield and yield attributes of coriander.
To find out the combined optimum rates of nitrogen, phosphorus, potassium and sulfur for maximizing seed yield of coriander.

Methodology:

Field experiment was conducted at Spices Research Centre, Shibgonj, Bogra during 2007-2008.The experiment was set up in a Randomized Complete Block Design (RCBD) with 16 treatment combinations having three replications. There were four levels of nitrogen (0, 40, 70 and 100 kg/ha), four levels of phosphorus (0, 25, 50 and 70 kg/ha), four levels of potassium (0, 30, 60 and 90 kg/ha), four levels of sulphur (0, 10, 20 and 30 kg/ha). The total amount of TSP, MP, and Gypsum were applied during final land preparation. Urea was applied 2 equal splits at 25 and 40 days after sowing. The unit plot size was 3m x 1.5m and seeds were sown at 22 December, 2007 and crop was harvested at its maturity 10 March, 2008. Yield contributing parameters were recorded from ten randomly selected plants from each unit plot. The recorded data on different parameters were statistically analyzed by using MSTAT software to find out the significance of variation resulting from the experimental treatments. The difference between the treatment means were judge by Duncan’s Multiple Range Test (DMRT) according to Gomez and Gomez.

Achievement/Findings:

All fertilizer treatments significantly increased plant height, number of umbel per plant, 1000 seeds weight and seed yield over control. Among the fertilizer treatments there were no significant difference in number of branches per plant and number of pod per plant due to application of nutrients. The lowest plant height (47.07cm) was recorded in control (T14) and the highest plant height (74.20 cm) was found treatment T_10. Moderate level of nutrients element applied to coriander had positive effect on plant height of coriander. The highest number of umbel per plant (39.37) was obtained treatment T₁₀ and the lowest was found in control. The data reveals that application of moderate doses of nutrients elements lead to produce higher number of umbel per plant. The highest weight of 1000 seed of coriander (6.03g) was recorded in treatment T₁₀being closely followed by the treatment T₆ and the lowest (4.20g) was obtained in treatment T₁₄. The highest seed yield (2.06t/ha) was recorded in treatment T₁₀ and it was close to treatment T₁₂ (1.81 t/ha) which gave the second highest yield. The relationship between seed yield and N, P, K and S were shown in figures 1, 2, 3 and 4. It might be concluded that potassium had a luxurious consumption by coriander and the soil had sufficient sulphur for coriander cultivation. Among fertilizer treatments, N70P50K30S20 highest seed yield was obtained (2.06 t/ha) and lowest seed yield(0.39 t/ha) was obtained in control. Nitrogen, phosphorus, potassium and sulfur played an important role in increasing yield of coriander. The fertilizer treatment N70P50K30S20was observed to be the best suitable dose for coriander cultivation on Grey Terrace Soil under AEZ-25.
