Study the Frequency of Solution Use in Selected High Value Horticulture Crops

AKM Salim Reza Mollik

M.R. Islam

Abstract/ Executive Summary:

Study the frequency of solution application in production of capsicum through hydroponics culture was conducted at the glass house of Olericulture Division, Horticulture Research Centre, BARI, Joydebpur, Gazipur, during October 2013 to March 2014. From the study it was found that the plant height was higher in T₂ (41cm) treatment followed by T₃ (35cm) and lowest in T₁ (32cm).The days to 1st flowering was earlier T₃ (30) and late in T4 (36days) treatment. The days to 50% flowering was earlier in T₂ (40 days) followed by T₁ (42) and late in T₃ (45 days). The 1st harvest was earlier in T₁ (55 days) late in T₃ (65 days). The number of fruits per plant was higher in T₁ (15) and followed by T₂ (12) and lowest in T₃ (10). Fruits size were large in T₁ (8.5x6.0cm) and small in T₂ (5.2x4.5cm). Individual fruit weight was higher in T₁ (110g) and lower in T₃ (78g). The yield per plants were heights in T₁ treatment(1.65kg ) and followed by T₂ (1.03kg) and lower in T₃ (0.78kg).

Start Date: 00-10-2013

End Date: 00-03-2014

Program Area: Crop-Soil-Water Management

Commodity: Capsicum

Objectives:

To identify the interval of nutrient solution application for successful capsicum production in hydroponic culture.

Methodology:

The experiment was carried out at the glass house of Olericulture Division, Horticulture Research Centre, BARI, Joydebpur, Gazipur, during October 2013 to March 2014. The study was set up in CRD design with three treatments and three replications. BARI Capsicum -1 was used as variety. The treatments were T₁= 15 days interval, T₂= 30 days interval T₃= 45 days interval. Water non Circulating methods were used. The seedlings were grown in sponge block. The sponge were cut into 2.5 cm cube size, in the middle of the cube the seeds were sown after that foam were placed in a tray (60x80x25cm) containing 30L fresh water. A news paper was placed over the Styrofoam to control the evaporation of water. After germination the newspaper was removed. At two to three true leaf stages 10 to 20 cc nutrient solutions were added at an interval of 2 to 3 days. After 3 to 4 weeks the seedlings were transplanted in individual plastic buckets. Each bucket contain 10 liter of water and 100ml of each nutrient solution ‘A’ and’ B’ adding in the bucket. The composition of nutrient solution to prepare 1000 liters solution: Potassium hydrogen phosphate 263.00g; Potassium Nitrate=583.00g; Calcium Nitrate=100.00g; Magnesium sulphate=515.00g; EDTA iron=79.00g; Manganese sulphate=6.10g; Boric acid=1.70g; Copper sulphate=0.39g; Ammonium molybdate:0.37g; Zinc sulphate=0.44g. Seedlings of cucumber were transplanted on November 15, 2012 and harvested up to March 2013.The intercultural operations such support the plant with nylon tape ,solution and acid adding etc. were done as and when necessary. The EC and pH were maintained 2.0 ds/m and 6.5 respectively. Data on Ec, PH, solution regularly and adjust EC and pH every days, temperature, yield and yield contributing parameters were recorded and statistically analyzed.

Achievement/Findings:

The highest yield was obtained from 15 days interval solution applicable (1.65kg/plant) and followed by 30 days interval (1.03kg/plant) and lowest in 45 days interval solution application (0.78kg/plant). The benefit cost return higher in T₁ (1:1.4) treatment and lower in T₃ (1:0.56). So T₁ treatment was profitable than other two treatments. For the above study It can be concluded that nutrient solution application after 15 days interval produced higher quantity of fruit of capsicum (1.65kg/plant) and lower in 45 days interval of solution application (0.78kg/plant).
