Abstract
Nutrient solution and its nutritional compositions may have the effect on growth and fruit quality attributes of cherry tomato. To avoid the build-up of toxins, mineral deficiencies, nutrition abnormalities, or the spread of disease, producers should use optimum level of nutrient solution. Therefore, the present experiment was conducted to identify a suitable strength of nutrient solution for cherry tomato in hydroponic system. Treatment considered six levels of nutrient solution [viz., S1: ½ strength Rahman and Inden (2012), S2: ¾ strength Rahman and Inden (2012), S3: Full strength Rahman and Inden (2012), S4: ½ strength Hoagland and Arnon No. 2(1940), S5: ¾ strength Hoagland and Arnon No. 2 (1940) and S6: Full strength Hoagland and Arnon No. 2 (1940)] and two varieties [viz., V1: Local market cherry tomato (red), V2: Irelands cherry tomato (yellow)]. Growth and yield contributing characters, quality parameters, physiological traits and biochemical composition were analyzed. The maximum plant height, number of leaves per plant, first flowering, number of flowers per cluster, number of fruit per cluster, number of cluster per plant, average individual fruit weight and average cluster weight per plant were found in S3. Meanwhile, V2 performed better in respect of plant height, number of leaves per plant, first flowering, number of flowers per cluster, number of fruit per cluster, number of cluster per plant, average individual fruit weight and average cluster weight per plant. Therefore, cherry tomato cv. V2 can be cultured in hydroponic system with applying S3 (Full strength Rahman and Inden nutrient solution).
Highlights
Agriculture of Bangladesh is under threats of climatic changes
The results revealed that the plant heights of tomato increased with the increased in the strengths of nutrient solutions
This might be due that full strength Rhaman and Inden solution has ability to supply proper amount of nutrients required for the cherry tomato culture in hydroponic system
Summary
Agriculture of Bangladesh is under threats of climatic changes. Climatic change is detrimental in our agriculture sector. Its advantages over conventional production systems are faster growth, higher productivity, easier handling, greater water efficiency Barbosa et al (2015) and lesser use of fertilizers Rana et al (2011) and Da Silva Cuba et al (2015) Hydroponics crop make it possible to obtain good quality products, when compared to conventional systems. The advantages in this system include the high crop quality and yield, lower expenses with fertilizers and a more efficient use of water, besides a reduction in the environmental pollution and a greater control and efficient in the productive process Logendra (2009) It is protected from unfavorable weather conditions because it is generally stationed in controlled environment greenhouses, and has the added capability of year-round production Spray and Spray (2019).
