Abstract/ Executive Summary:

The study was conducted in the field at Nagarpur, Tangail, Bangladesh, from November 2016 to February 2017 to find out the role of honey bees on mustard yield. Honey bee (Apis mellifera) was the main insect pollinator during mustard flowering season. Mustard seeds of variety Tori-7 were selected for this experiment. Three different treatments were used, viz. control, netting with honey bees and netting without honey bees. Honey bees helped mustard pollination, but decreased the flowering period (6 days) of the mustard plant. Honey bees assisted the pollination of mustard and increased the number of pod per plant (14%) as well as the number of seeds per pod (11%). Honey bees enhanced the pollination of mustard plant, and netting with honey bees increased the mean seed yield (15%) per plant of mustard, however, decreased the period of flowering stage of mustard. Mustard yield was considerably higher in honey bee foraging plots.

Objectives:

To study the role of honey bees on mustard yield in Bangladesh perspective.

Methodology:

The experiment was carried out during the period from November 2016 to February 2017 to find out the effect of honey bee foraging in mustard field and role of honey bee on mustard yield. The study was conducted in the field at Nagarpur, Tangail. The soil of the experimental area belongs to the Modhupur Tract under AEZ No. 28 and it was dark grey terrace soil. The mustard seeds of variety Tori-7 were selected for this experiment. The variety was local one and improved by the Bangladesh Agricultural Research Institute (BARI) in the year of 2004. The plant height of this variety ranges 60-75 cm and the life cycle is 70 -75 days when cultivated in robi season. The experimental plot was opened in the first week of November 2016 with a power tiller, and was exposed to the sun for a week, after which the land was harrowed, ploughed and cross-ploughed several times followed by laddering to obtain a good tilt. Weeds and stubble were removed, and finally obtained a desirable tilt of soil for sowing mustard seeds. The experiment was conducted considering three treatments and laid out in a completely randomized design (CRD). Each treatment was replicated four times. Field trials were conducted during the winter season in the field at Nagarpur, Tangail. The unit plot size was 2.5m x 1.2m. The distance between plots and blocks was 50 cm and 100 cm, respectively. Row to row distance for mustard was 25 cm. Similar distance was maintained when seeds were sown. The fertilizers N, P, K, S, Zn and B in the form of Urea, TSP, MP, Gypsum, Zinc sulphate and borax, respectively were applied. The entire amount of TSP, MP, Gypsum, Zinc sulphate and borax were applied during the final preparation of land. Urea was applied in two equal installments at final land preparation and at 30 days of seed sowing. The seeds of mustard were sown insole and in intercrop plot on 26 November 2016. After the establishment of seedlings, all other intercultural operations, such as thinning, weeding, and irrigation were accomplished, when necessary, for better growth and development of the mustard crop. Single irrigation had been applied just once before flower initiation. The plots were provided with well-arranged drainage facilities including the facility of removing excess rainwater if any. Weeding was done twice in the field to keep the plots free from weeds ensuring better growth and development of the crops. The newly emerged weeds were uprooted carefully at the flowering stage by mechanical means. For the experiment, a piece of net was set up over a selected plot on 18 December 2016, so that only honey bees present in the selected plots. The net size was 2.5 m x 1.2m x 2.5m. For the experiment, boxes were set up over selected plots on 31^st December 2016. Mustard harvesting at maturity (days of sowing) was done manually in each plot. The harvested crops of each plot was bundled separately, properly tagged and brought to shade. Care was taken for harvesting, threshing and also cleaning of mustard. The seeds were cleaned and finally the weight was recorded and converted into per hectare yield. Mustard of each plot was threshed separately, cleaned, sun-dried, weighed and packed. Data were analyzed by IBM SPSS 25 software for proper interpretation. The data recorded on different parameters were subjected to analysis of variance (STAT Graphics Centurion XV) and means were compared by Duncan’s Multiple Range Test (STAT Graphics Centurion XV) at 5% level of significance.

Achievement/Findings:

Finding the result pod length was higher compared to other treatments in open conditions due to different pollinators’ presence. Pod length is short in without bee condition of field due to lack of pollination and malformation of pod. Number of seeds was found higher in bee netted condition compared to other treatments due to well pollination, but the seed sizes are comparatively smaller hence resulted in the less weight of the 1000 number of mustard seeds. Though the seed size is small, but the total yield was the highest in the netted bee condition due to well pollination of mustard flower.
