Abstract/ Executive Summary:

An experiment was carried out at the BAU Germplasm Centre (GPC) of Bangladesh Agricultural University, Mymensingh during the period from September 2010 to February 2011 to examine the effect of management practices on the growth and yield of jujube (BAU Kul-1, BAU Kul-2 and Apple Kul). The experiment consisted of two factors viz. management and variety.. The experiment was laid out in Randomized Complete Block Design with three replications. Results revealed that, canopy volume, weight of individual fruit and total harvested fruit per plant were found maximum in BAU Kul-1 with pruning + manuring + irrigation. Maximum Numbers of leaves was found in BAU Kul-2 with manuring. The yield per hectare was the highest (10808.97t/ha) from BAU Kul-1 with the found of pruning + manuring + irrigation whereas the lowest (206.11 t/ha) was obtained from the Apple Kul with control.

Keywords: Jujube, Variety, Management, Growth, Yield

Location: BAU Germplasm Centre (GPC) of Bangladesh Agricultural University, Mymensingh

End Date: 00-02-2011

Program Area: Crop-Soil-Water Management

Commodity: Jujube, Jujube

Objectives:

1. To examine the effect of management practices on the growth and yield of jujube.

Methodology:

The present study was conducted to investigate the effect of management practices on the growth and yield of three varieties of jujube at the BAU Germplasm Centre of Fruit Tree Improvement Programme (GPC-FTIP), Bangladesh Agricultural University, Mymensingh during the period from September 2010 to February 2011. High yielding cultivar namely BAU Kul-1, BAU Kul-2 and Apple Kul were used in this study. It includes a short description of experimental site, duration of the experiment, soil, climate, materials used for the study, treatments and layout, and application of fertilizer, intercultural operations, and methods of assignment of different treatments, harvesting, and collection of data, chemical analysis and statistical analysis. The experimental area is situated in the subtropical zone, characterized by heavy rainfall during Kharif season (April to September), and scanty in Rabi season (October to March). The soil of the experimental area is sandy loam type and belongs to the Old Brahmaputra Flood Plain Alluvial Tract ( UNDP, 1988). The experimental site was a medium high land and the pH of the soil was 6.7. The experiment was done on 3 years old jujube plant of BAU Kul-1, BAU Kul-2, and Apple Kul which were previously planted. The two factor experiment was laid out in Randomized Complete Block Design (RCBD) with three replications; the total number of plant was 8×3×2=48. Planting was in hexagonal systems giving spacing of 4m×4m. The experiment consisted of two factors, details of which are described below: Factor A. Management practices on i) Pruning, ii) Manuring, iii) Irrigation, iv) Pruning + Manuring, v) Manuring +Irrigation, vi) Irrigation + Pruning, vii) Pruning + Manuring+Irrigation, viii) Control Factor B: Varieties on i) BAU Kul 1, ii) BAU Kul 2, iii) Apple Kul. Canopy volume was calculated at 30 days interval starting from September, 2010 to January, 2011. Canopy volume (m)³ = 4/3a²b, where a = half of the height, b = average of east-west and north-south plant spread was expressed in m³. The data collected from the experiment were statistically analyzed. The mean values of all treatments were calculated and the analysis of variance for most of the characters was accomplished by F variance test. The significance of difference among the treatment means was evaluated by least significance difference (LSD) test at 5% and 1% levels of probability.

Achievement/Findings:

Combined effect of variety and treatments on yield per hectare was significant. It was found that variety BAU Kul-1 along with pruning + manuring + irrigation produced the highest yield per hectare (10808.97 t/ha). On the other hand, Apple Kul with control resulted the lowest yield per hectare (206.11 t/ha).
