Abstract/ Executive Summary:

An experiment on coriander (Coriandrum sativum L.) was conducted at the experimental field of Department of Horticulture, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur during November 2012 to April 2013 to find out the suitable foliar doses and application frequency of urea and planofix (NAA). The experiment was laid out in factorial randomized complete block design with three replications. The treatment consisted of six foliar dozes viz. T₁ (Tap water as control), T₂ (0.10 % urea), T₃ (0.25 % urea), T₄ (0.40 % urea), T₅ (5 ppm planofix) and T₆ (10 ppm planofix) and three application frequencies viz. F₁ [20 days after sowing (20 DAS)], F₂ (30 DAS) and F₃ (20 and 30 DAS). Maximum foliage yield (6.94 t/ha) was recorded in 10 ppm planofix coupled with it’s twice application at 20 and 30 DAS which was closely followed the foliage yield (6.33 t/ha) by 5 ppm planofix with the same application frequency. The foliage yield was increased with the increase in urea concentration. The highest foliage yield (5.37 t/ha) was also recorded from twice application of urea and planofix at 20 and 30 DAS, respectively. Planofix 10 ppm with its twice application at 20 and 30 DAS gave the highest benefit-cost of ration 2.51.

Start Date: 00-11-2012

End Date: 00-04-2013

Program Area: Crop-Soil-Water Management

Commodity: Coriander

Objectives:

To determine the profitable foliar doses and application frequency of urea and planofix for coriander cultivation.

Methodology:

The experiment was conducted at the Horticulture Research Farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during the period from November 2012 to April 2013 to study the effect of urea and planofix on coriander foliage yield. The field experiment having two factors was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatment consisted of six foliar dozes viz. T₁ (Tap water as control), T₂ (0.10 % urea), T₃ (0.25 % urea), T₄(0.40 % urea), T₅ (5 ppm planofix) and T₆ (10 ppm planofix) and three application frequencies viz. F₁ [20 days after sowing (20 DAS)], F₂ (30 DAS) and F₃ (20 and 30 DAS). Replication to replication and plot to plot distance were 1.0 m and 0.5 m, respectively. The size of each unit plot was 3 m x 1 m (3 m² ). The total area of the experiment was 332 m² . Total number of plots was 54. The planofix is a product of Buyer Crop Science containing NAA use as foliar spray. The variety Rosina of Pahuja seed company, India was used as plant material. The seeds (fruits) were rubbed for separating two mericarps (seeds) and were soaked in water for 24 hours to enhance germination. Seed were also treated with Bavistin @ 2 g per kg of seeds before sowing. The seeds were sown in rows 10 cm apart continuously by hand @ 40 kg/ha. To allow uniform sowing in rows seeds were mixed with some loose soil and watering after sowing just to supply sufficient moisture needed for quick germination. The field was kept weed free initially by hand weeding. Weeding was done after 25 days after sowing (DAS). Data were recorded on the plant spread , plant height, longest leaf length, leaves per plant, plant weight, green plants/m², green plant weight/m² , foliage yield (t/ha). All the data were compiled and analyzed statistically by MSTAT--C program. The mean comparison was done at 5% level of probability following the Duncan`s Multiple Range Test (DMRT).

Achievement/Findings:

The growth parameters viz. plant spread, plant height, leaf length, leaves/plant, plant weight, plant weight/m² and foliage yield were found maximum from the foliage spray of 10 ppm planofix as well as it twice application at 20 and 30 days after sowing. Planofix 5 ppm in combination with it’s twice spray at 20 and 30 DAS produced the second highest foliage yield of coriander. The solution of urea 0.40% coupled with twice spray at 20 and 30 DAS produced reasonable foliage yield of coriander. Thus, 10 ppm planofix with its twice application may be used for maximum production of foliage yield of coriander.
