Abstract
The impact of chemical farming and the negative consequences on the environment and human health in Bangladesh are on the rise. Organic farming is gaining attention and increasing globally because it is eco-friendly, safe and has benefits for human health. A field study was conducted at the horticulture farm of Bangladesh Agricultural University (BAU), Mymensingh, to evaluate the growth and yield performance of cabbage cv. Atlas—70 using organic and inorganic fertilizers in various plant spacing arrangements. Two factor experiments were conducted on plant spacings of 60 cm × 40 cm (S1), 60 cm × 50 cm (S2) and 60 cm × 60 cm (S3) and fertilizers vermicompost (T1), biogen (T2), integrated plant nutrient system (IPNS) Organic (⅔) + inorganic (⅓) (T3) and inorganic (T4). IPNS (T3) application increased the marketable yield (54.77 t·ha−1) of cabbage. The highest marketable yield (48.75 t·ha−1) was obtained with a plant spacing of 60 cm × 40 cm (S1). No significant variation was found in plant spacings S1 and S2. The treatment combination of S2T3 recorded the highest plant height (37.81 cm), plant spread (47.75 cm), cabbage head (21.80 cm), stem length (12.31 cm), thickness of the cabbage head (12.53 cm) and marketable yield (65.0 t·ha−1). The results suggest that IPNS (T3) combining organic and inorganic fertilizer applications with a 60 cm × 50 cm spacing (S2T3) increases the yield performance of cabbage.
Highlights
The sustainability of conventional agriculture in Bangladesh is under threat from the continuous degradation of land and water resources, as well as declining yield due to indiscriminate use of agro-chemicals
There are mixed fertilizers or integrated plant nutrient systems (IPNS) where organic fertilizer is combined with inorganic fertilizer for soil improvement and higher yield
The soil pH and electrical conductivity (EC) increased after harvesting the crop [24].The average yield of cabbage was significantly influenced by the organic and inorganic fertilizer treatments and plant spacings
Summary
The sustainability of conventional agriculture in Bangladesh is under threat from the continuous degradation of land and water resources, as well as declining yield due to indiscriminate use of agro-chemicals. There are mixed fertilizers or integrated plant nutrient systems (IPNS) where organic fertilizer is combined with inorganic fertilizer for soil improvement and higher yield. This reduces the dependency and need for a higher amount of inorganic fertilizer in crop production. Plant spacing and fertilizer applications have significant influence on the growth and yield in crop production. The judicial application of organic or inorganic fertilizers is an important consideration to improve the yield and quality of the product. The objective of the work is to evaluate the growth and yield performance of cabbage in various plant spacing arrangements using different organic and inorganic fertilizers
