Abstract/ Executive Summary:

The present study aimed to evaluate the growth and yield attributes of lime and lemon under different cultural management practices. The experiment consisted of four years old three lemon varieties viz. BAU Lebu-1, BAU Lebu-2, and BAU Lebu-3 and eight management practices such as pruning, manuring, irrigation, pruning + manuring, manuring + irrigation, irrigation + pruning, pruning + manuring + irrigation and control (no treatment). Results revealed that the highest plant height, canopy volume, and yield were found in BAU Lebu-3 (Semi seedless), while lowest was recorded in BAU Lebu-2, though highest number of fruits plant-1 and its percent edible portion were found in BAU Lebu-1 (Kagzi). For interaction effects, pruning together with manuring and irrigation exhibit the highest plant height, canopy volume, and yield in BAU Lebu-3, however, maximum number of fruits and percent edible portion were observed in BAU Lebu-1. The lowest plant height, canopy volume, number of fruits, percent edible portion and yield were obtained in BAU Lebu-2 with control treatment. The results of the present study suggest that BAU Lebu-3 along with treatment combination of pruning + manuring + irrigation can be produced with the highest growth and yield in the off-season.

Keywords: Management practices, Canopy volume, Percent edible portion, Growth, Lime, Lemon

Location: Germplasm Centre of Bangladesh Agricultural University, Mymensingh

Start Date: 00-08-2010

End Date: 00-01-2011

Program Area: Crop-Soil-Water Management

Commodity: Lemon

Objectives:

To observe the effect of divergence management practices on the growth and yield of lemon and lime.

Methodology:

Study location The present experiment was conducted at the Germplasm Centre of Bangladesh Agricultural University, Mymensingh during the period from August 2010 to January 2011. Experimental materials The experiment was done on four years old citrus plants (BAU-Kagzi lebu, Semi seedless lebu and Elachi lebu). The plants were more of less established by layers and planted in 2007 and all the plants were uniform in size. The plants were under the partial shade of aonla, horitoki and bohera trees. Experimental design and treatments The Two-factor experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Each block contains 24 plants. Per replication, there was a single plant. Thus the total number of plants were (3×8×3×1) = 72. In each block, combination of different treatments and varieties were assigned randomly. Planting was in hexagonal system giving spacing of 4m×4m. The experiment was designed to study the effect of different types of management practices (Pruning, manuring and irrigation application) on the fruiting of lime and lemon. The experiment consisted of two factors, which were as follows: Factor A: Types of citrus fruits, viz. V₁ = BAU Lebu-1 (Kagzi), V₂ = BAU Lebu-2 (Elachi scented) and V₃ = BAU Lebu-3 (Semi seedless) and Factor B: Treatment, viz. T₁ = pruning, T₂= manuring, T₃ = irrigation, T₄ = pruning + manuring, T₅ = manuring + irrigation, T6 = irrigation + pruning, T₇ = pruning + manuring + irrigation and T₈ = control (no pruning + no manuring + no irrigation). Management practices Pruning was done on 12 August 2010. Diseased, dead, unproductive branches, cross branches, shoots, water sprouts and leaves were pruned with the help of secateurs as per treatment. All plants were pruned in same height and almost same number of branches was kept. The application of manures and fertilizers was done immediately after pruning and before blossoming. All the manures and fertilizers were mixed together and applied around the plant base with sufficient care. All the treatments were fertilized with 30kg-350g-300g-300g-1kg per plots cow dung- urea-TSP-MP-paragon super respectively. When fertilization of all plants was completed, then irrigation was applied by supplying pipe and subsequent irrigation was done as and when required. Intercultural operation was done as when necessary. Data collection and analysis Data were recorded on plant height (cm), canopy volume (m3), number of leaves per plant, time of flowering, time of fruit setting, time of harvesting, no. of total fruits per plant, number of harvested fruits per plant, number of damage fruits per plant, weight of individual fruit (g), length and breadth of fruit (cm), weight of pulp (g), weight of peel (g), percent (%) edible portion, total soluble solids (TSS%), Yield per plant (kg), yield per hectare (t/ha) from each plant. In case of fruit, five (5) fruits were selected at random from each plant labeled and data were recorded after harvesting of the fruits. The recorded data were analyzed following Gomez and Gomez (1984) and means were compared at the 5% level of probability.

Achievement/Findings:

From the present study, it may concluded that the offseason fruit yield of lime and lemon could be increased successfully through proper cultural management practices and by cultivating the recommended varieties; BAU Lebu-1, BAU Lebu-2 and BAU Lebu-3.
