Abstract/ Executive Summary:

An experiment was conducted at the research field of Horticulture Research Centre, BARI, Gazipur during Rabi season of 2012-13 to 2014-15 to evaluate the response of different doses of N, P and K on the yield and yield attributes of chrysanthemum (var. BARI Chrysanthemum-1) and to find out the optimum and economic doses of NPK for maximizing yield of chrysanthemum. Treatments comprising four levels each of N (0, 100, 150 and 200 kg ha^-1), P (0, 50, 75 and 100 kg ha^-1) and K (0, 90, 135 and 180 kg ha^-1) along with blanket dose of 2 kg B and 4 kg Zn ha^-1 were used. The treatments were assigned in a randomized complete block design with three replications. The combined effect of NPK significantly increased yield and yield attributes of chrysanthemum for each of the yearly experiments as well as the average of three years results. Significantly, the highest flower yield (12.45, 11.47 and 11.96 t/ha) was obtained with the application of N₁₅₀P₇₅K₁₃₅ kg ha^-1 (T₃) along with blanket dose of 2 kg B and 4 kg Zn ha^-1 for the years of 2012-13, 2013-14 and 2014- 15, respectively and it was statistically identical with T₄ (N₂₀₀P₇₅K₁₃₅ kg ha^-1) treatment. Application of 150 kg N, 75 kg P and 135 kg K increased yield by 52.76, 42.29 and 36.51%, 152.08, 126.23 and 99.13% and 88.35, 51.30 and 60.75%, respectively, over their control in respect to the years. The highest benefit-cost ratio 5.54 followed by 5.14 was obtained from T₃ (N₁₅₀P₇₅K₁₃₅ kg ha^-1) followed by T₄ treatment, respectively. From the quadratic regression equation averaging three years data the optimum and economic doses 155 and 151.8 kg N, 79.3 and 77.68 kg P and 118.75 and 115.7 kg K, respectively were found which could be recommended for chrysanthemum production in Grey Terrace Soil of Joydebpur under AEZ 28.

Objectives:

The present study was undertaken to evaluate the response of N, P and K on the yield and yield attributes of chrysanthemum and to find out the optimum and economic doses of NPK for maximizing yield of chrysanthemum in Grey Terrace soil of Joydebpur, Gazipur.

Methodology:

Three years experiments were conducted at the Horticultural Research Farm, BARI, Joydebpur, Gazipur during Rabi season of 2012-13 to 2014- 15 to evaluate the response of N, P and K on the yield and yield attributes of chrysanthemum and to find out the optimum and economic doses of NPK for maximizing yield of chrysanthemum. The soil test values showed that the experimental soil was deficient in nutrients especially N, P and K. The field experiment was set up in a randomized complete block design with three replications. Treatments comprising four levels of fertilizer nutrients each of N (0, 100, 150 and 200 kg ha^-1), P (0, 50, 75 and 100 kg ha^-1) and K (0, 90, 135 and 180 kg ha^-1) along with a blanket dose of 2 kg B and 4 kg Zn ha^-1 were used. The unit plot size and plant spacing were 2 m x 1.50 m and 40 cm x 30 cm, respectively. Every plot except control plot had received blanket dose of 2 kg B and 4 kg Zn ha^-1. The variety BARI Chrysanthemum-1 was used as the test crop. Urea, TSP, MoP, boric acid and zinc sulphate were used as a source of N, P, K, B and Zn, respectively. Total amount of P, K, B, Zn and 1/3^rd N were applied at the time of final land preparation and the remaining N were applied in two equal splits each at 30 and 45 days after planting, respectively. Thirty days old seedlings were transplanted on 27^th November, 2012; 2^nd December, 2013 and 6^th November, 2014, respectively. Intercultural operations such as weeding, irrigation etc. were done as and when required. Flowers were harvested four times from 13^th February to 8^th March, 2013, 13^th February to 12^th March, 2014, 24^th January to 2^nd March, 2015, respectively. Data on growth, yield and yield contributing characters were recorded from ten selected plants at each treatment. The collected data were analyzed statistically using the statistical package MSTAT-C.

Achievement/Findings:

From three years study, results indicated that judicious nutrient management in chrysanthemum can ensure high profit. Application of 150-75-135 kg NPK ha^-1 along with blanket dose of 2 kg B and 4 kg Zn ha^-1 showed the best performance for chrysanthemum production. From quadratic regression equation averaging three years data 155 kg N, 79.3 kg P and 118.75 kg K ha^-1 and 151.8 kg N, 77.68 kg P and 115.7 kg K ha^-1, respectively were found as the optimum and economic doses which could be recommended for chrysanthemum production in Grey Terrace Soil of Joydebpur under AEZ 28.
