Abstract
Field trials were conducted on tomato for yield and quality of fruits using different types of organic and inorganic fertilizers at the horticulture farm of Bangladesh Agricultural University (BAU), Mymensingh. Fertilizer treatments were tested on two varieties of tomato ca. Roma VF and BARI 15. The fertilization treatments were T1, vermicompost (12 t/ha); T2, compost (10 t/ha); T3, integrated plant nutrient system (IPNS) or mixed fertilizers (organic 2/3 part and inorganic 1/3 part); T4, inorganic fertilizers; and a control (T5). Results showed growth and yield (20.8 t/ha) in tomato were higher in the IPNS treatment. A higher number of fruits per plant (73.7) and plant height (73.5 cm) were obtained from mixed fertilizers (organic 2/3 + inorganic 1/3) or IPNS (integrated plant nutrient system) in Roma VF than other treatments. Fruit yield and diameter were found statistically significant. No significant difference was observed in the quality (total soluble solids) of tomato fruits in both varieties’ response to the treatments. The electrical conductivity and pH of the soil were improved by the application of organic manure.
Highlights
The organic production system aims at supporting and sustaining healthy ecosystems, soil, farmers, food production, the community, and the economy
Reduction and elimination of the adverse effects of synthetic fertilizers and pesticides on human health and the environment is a strong indicator that organic agriculture is gaining worldwide attention [1,2]
The analysis ofDiscussion variance results showed that the effect of mixed fertilizers on tomato yield was
Summary
The organic production system aims at supporting and sustaining healthy ecosystems, soil, farmers, food production, the community, and the economy. Solaiman and Rabbani [11] reported results and their findings on the application of a combination of cow dung and a half dose of inorganic fertilizer. Bio fertilizers such as Trichoderma enriched with inorganic fertilizers play a significant role in the growth and yield of crops, e.g., mustard and tomato, and have the potential to reduce 50% of the cost of inorganic fertilizers [12]. The objective of this research project was to evaluate the effect of organic and inorganic fertilizers combined on the growth, yield and quality of tomato and on soil properties
