Abstract/ Executive Summary:

(PSTU) during November 2011 to April 2012 to assess the growth and yield performance of onion as influenced by different organic manures. The experiment comprised four levels of organic manures viz., poultry manure, cowdung, compost and musterd oil cake and two onion varieties viz., BARI Piaz 4 and Faridpur vati. The two-factor experiment was laid out in the randomized complete block design (RCBD) with three replications. Data were collected on growth and yield components of onion. Statistically significant variation was observed in respect of variety, manure treatments and their combinations. Growth characteristics, viz., plant height, number of leaves per plant and leaf length was better with BARI Piaz 4 (48.87, 7.90 and 42.86 cm, respectively) and poultry manure (50.32, 7.82 and 44.26 cm, respectively). The variety BARI Piaz 4 and poultry manure performed the best on production of fresh weight (39.55 and 42.22 g, respectively) and dry weight of bulb (32.89 and 41.97 g, respectively. In respect of variety, the highest yield (13.62 t/ha) was found from the variety BARI Piaz 4. Among the organic manure treatments, the highest yield (13.70 t/ha) was observed from poultry manure, where as the lowest yield (11.80 t/ha) was marked from control treatment. In case of combined effect the highest yield (14.72 t/ha) was obtained from the treatment combination of poultry manure and BARI piaz 4.

Keywords: Onion, Organic manures, Growth and yield

Location: Research Farm of Patuakhali Science and Technology University (PSTU)

Start Date: 00-11-2011

End Date: 00-04-2012

Program Area: Crop-Soil-Water Management

Commodity: Onion

Objectives:

1. To study the influence of organic manures and their combinations on growth, yield and quality of onion. Hence, the present study was undertaken to assess the growth and yield performances of onion varieties as influenced by different organic manures.

Methodology:

The experiment was carried out at the Research Farm of Patuakhali Science and Technology University (PSTU) during November 2011 to April 2012 to assess the growth and yield performance of onion as influenced by different organic manures. The experiment comprised four levels of organic manures viz., poultry manure, cowdung, compost and musterd oil cake and two onion varieties viz., BARI Piaz 4 and Faridpur vati. The two-factor experiment was laid out in the randomized complete block design (RCBD) with three replications. The land which was selected to conduct the experiment was opened 1st December 2011 with the help of a power tiller and then it was kept open to sun for 7 days prior to further ploughing. Afterwards it was prepared by ploughing and cross ploughing followed by laddering. Different organic manures such as poultry manrue, cowdung, compost and mustard oil cake were applied in the field at 15 days before transplanting as per the treatments and finally incorporated with the soil one day before transplanting. The 45 days young plants of assigned two onion varieties were transplanted in the research field on December 14, 2011. Different intercultural operation was done to keep the plots free from weeds and for better aeration of soil. Data from the experiment were statistically analyzed in MSTAT-C computer program. The mean values for all the parameters were calculated and the analysis of variance for the characters was accomplished by ‘F’ test. The significance difference between two pair of means was tested by the Duncan’s Multiple Rnage Test (DMRT) at 5 % levels of probability.

Achievement/Findings:

Statistically significant variation was observed in respect of variety, manure treatments and their combinations. Growth characteristics, viz., plant height, number of leaves per plant and leaf length was better with BARI Piaz 4 (48.87, 7.90 and 42.86 cm, respectively) and poultry manure (50.32, 7.82 and 44.26 cm, respectively). The variety BARI Piaz 4 and poultry manure performed the best on production of fresh weight (39.55 and 42.22 g, respectively) and dry weight of bulb (32.89 and 41.97 g, respectively. In respect of variety, the highest yield (13.62 t/ha) was found from the variety BARI Piaz 4. Among the organic manure treatments, the highest yield (13.70 t/ha) was observed from poultry manure, where as the lowest yield (11.80 t/ha) was marked from control treatment. In case of combined effect the highest yield (14.72 t/ha) was obtained from the treatment combination of poultry manure and BARI piaz 4.
