Abstract/ Executive Summary:

Effect of soil incorporated Tricho-compost @ 5.5 t/ha (T₁) and foliar spray of Tricho-leachate @ 4 ml/l at 15 days interval (T₂) each alone or in combination (T₃) were evaluated on mortality of strawberry plant in the maintenance nursery and growth and development of daughter plants in the main filed. Traditional practice of maintenance of plants in the nursery bed was considered as control (T₄). The study was conducted at the Regional Horticultural Research Station, Bangladesh Agricultural Research Institute, Sibpur, Narsingdi, during June 2015 to March 2016 and BARI Strawberry-1 was used in the study. The lowest mortality (6.67%) in the nursery bed was recorded in saplings treated by T₃, while the highest mortality (16.67%) was recorded in the control plot (T₄) and the trend was also followed in the main field. Days to flowering (47.67) and days to first harvest (71.67) of saplings treated by T₁ were earlier as compared to that of saplings of control plot (60.67 and 93.33 respectively). The maximum harvest duration was recorded in saplings treated by Tricho-compost (74 days) followed by T₂ (61.33 days) and T₃ (59.33 days). Total Soluble Solid (TSS) of fruits were also improved when the plants were treated by Tricho-products. The maximum fruit yield (621.68g per plant) was recorded from T₃; while, the lowest yield (396.83g per plant) was recorded in saplings treated by Tricholeachate @ 4ml/l.

Start Date: 00-06-2015

End Date: 00-03-2016

Program Area: Crop-Soil-Water Management

Commodity: Strawberry

Objectives:

To find out the effectiveness of Tricho-compost and Tricho-leachate on survivability of strawberry plants in the maintenance nursery including growth and development of subsequent daughter plants in the main field.

Methodology:

The experiment was conducted at the Regional Horticulture Research Station (RHRS), Sibpur, Narsingdi during June 2015 to March 2016. Land type of the experimental plot was sandy loam. Inherent nutrient status of the soil was estimated before starting the experiment and data are presented in Table 1. The experiment consisted of four treatments which are as follows: T₁= Soil incorporated Tricho-compost @ 5.5 t/ha; T₂= Foliar application of Tricho-leachate @ 4 ml/l at 15 days interval; T₃= Combined application of T₁+T₂; T₄= Control (Traditional practice of maintenance of plants in the nursery bed); Tricho-compost, a Trichoderma based compost fertilizer, was prepared at the Horticulture Research Centre (HRC), BARI, Joydebpur, Gazipur following the procedure described by Nahar et al. (2012) by mixing a definite concentration of spore suspension of a Trichoderma harzianum strain with measured amounts of processed cow-dung, poultry refuse, water hyacinth, vegetable wastes, sawdust, maize bran and molasses. Tricho-leachate, a liquid by-product of the Trichocompost, was obtained during decomposition of Tricho-compost materials. Required Tricho-compost and Tricho-leachate were collected from the HRC. Nutritional status of Tricho-products was determined in the Laboratory of the Soil Science Division, BARI, Joydebpur in February 2015 and results are presented. The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications. The unit plot size both for nursery and crop field consisted of 1m x 3m, accommodating 12 plants in double rows planting system with 50 cm × 40 cm spacing. The plants of the previous crop were transferred in the maintenance nursery in 2nd week of June 2015. The nursery beds were treated with Tricho-compost @ 5.5 t/ha as per treatment allocation. Foliar application of Tricho-leachate was done @ 4 ml/l of water at 15 days interval. Blanket doses of cowdung, Urea, TSP, MoP, gypsum, zinc sulfate, borax were applied at the rate of 30 t/ha and 250, 200, 220, 150 10 and 12 kg/ha, respectively in the field before planting (Mondal et al., 2011). Same fertilizers with similar doses were used in the main filed. Thirty day old sapling having three to four leaves obtained from each treatment were transplanted in the main field in 2nd week of November 2015. Same treatments of Tricho-products and similar plot sizes as used in nursery beds were followed in the main field for growing crop. Plants in the main field were covered with shade net that cuts thirty percent light to provide partial shade and also acts as a bird invasion protector. Data on 1st flowering date, 1st harvesting date, harvest duration, plant height and spreading of plant at 1st harvest, number of leaves/plant at 1st harvest, cumulative number of fruits/plant, weight of individual fruit, fruits length, fruits breath, TSS% of fruit, yield per plant were recorded. Data on plant mortality per cent was transformed by following ARCSIN transformation. Collected data were analyzed statistically and means were separated by LSD.

Achievement/Findings:

It appears that Tricho-compost and Tricho-leachate enhance flowering, fruit set and vegetative growth of strawberry with the added benefits of control of soil borne diseases in the field. Early harvesting could clearly be of great benefit to the growers. Soil incorporation of Tricho-compost with foliar application of Tricho-leachate was the most appropriate combination of Tricho-products.
