Abstract/ Executive Summary:

Plasticulture technique is a commonly used technique for advanced strawberry production. Due to high cost and tough maintenance, this technique is not practiced commercially in Bangladesh. It is observe that, if the irrigation system can be switched to a cheaper one with high efficiency, then the cost can be minimized. It applied Micro-drip mediated irrigation system to minimize the cost. The proposed modification of plasticulture using micro-drip irrigation system was outstanding in all our concerned horticultural parameters like height of the plants, number of leaves, north-south spreading, and east-west spreading of the plants. Paired Samples analysis between conventional and plasticulture procedure, test of significance for the pairs of mean, analysis of variance and LSD test at 5% level of significance were done for statistical analysis to conclude the result. The statistical analysis had also shown that the plasticulture method proposed by us was highly significant over the conventional technique and practical for the rural farmer of Bangladesh. It reduces the production costs, improves fruit quality and yield, and reduces the need for chemical pesticides.

Objectives:

The objective of this study was to develop a farmer friendly cultivation system of strawberry.

Methodology:

The entire experiment was conducted in the village of Usmaninagar Thana named Thanagaon, in Sylhet district of Bangladesh. Soil preparation & soil pH: The experimental field was prepared by ploughing the land well and the soil pH and solarization was done. The optimum Soil P^H (6.0-6.2) for strawberry cultivation was adjusted using dolomitic lime. The soil pH 6.1 was reported prior to sowing the saplings in the field. Soil solarization: Solarization of soil was done as described by Chen et al (1991) with some modifications. It covered the soil with black plastic in order to reduce the soil borne pathogen through passive capture of solar radiation, as a substitute of chemical fumigants. Bed Preparation & mulching: Cultivation beds were prepared manually. The size and shape of each bed was 10-inch deep with 30 to 32 inches wide at the base and 26 to 28 inches wide on top to ensuring the slope. Black, thick (1.00-1.25 mm), long lasting and re-useable plastic mulch were manually installed to the prepared bed. The bed was checked for air tight quality, which was ensured by covering the mulch ends with mud. Irrigation system: Conventional and micro drip adapter mediated irrigation systems were followed in our current investigation. The conventional irrigation was done by manual water sprayers while micro drip adapter mediated irrigation was adorned with saline bags (used) by removing the canula (needle) and drip chamber from the bag. The bags with tube, micro drip adapter (controller), drip and dropper were thoroughly washed 3-5 times in detergents, slightly hot water and dried, in order to remove any uncertain chemicals. The upper portion of the bag was cut by a sharp knife smoothly to pour water into the bag for irrigation. Then one bag was hung beside each strawberry plantlet by a support and the tube was inserted into the plastic mulch and the controller remained outside the mulch. The micro drip adapter was manually switched to fully forcing mood. Planting: For each experimental block 200 saplings were planted. The saplings were collected form Plant genetic engineering Lab. of Department of Genetic Engineering and Biotechnology, which were produced through tissue culture approach (Zobayer et al,2011). The plastic mulch were cut by a sharp knife in round shape (as smaller as possible) and the saplings were planted 18 inch apart from each other. Statistical Analysis: SPSS 10.0 software was used for the analysis of experimental data. Paired sample analysis, Test of significance, ANOVA test and LSD (Latin Square Design) test were carried out the efficient process of strawberry cultivation.

Achievement/Findings:

By all statistical mean the data set of plasticulture is better than conventional method. As switched of the irrigation system of the plasticulture technique, which made the technique much cheaper than the previously practiced plasticulture technique. The plasticulture technique proposed by us was more suitable for the agricultural condition of Bangladesh, as it was higher yield, quality fruit production, lower or zero use of chemical pesticides, low experience is required for maintenance as well as season extending method with a profitable cost benefit ratio.
