Abstract
Tropical soils are characterized by inadequate fertility, low pH, organic matter, inability to take up nutrients, and lower crop yield. The nutrition provided by organic inputs might have solved some of these problems rather than solo chemical fertilizers. Therefore, a combination of soil amendment with banana pseudostem-based compost and foliar spray of banana pseudostem sap was tested to evaluate the sweet corn’s nutrient uptake, yield, and quality. The study included four levels of banana pseudostem-based co-compost (BPC), viz., CF: control (100% recommended chemical fertilizers); C5: 5 t ha−1; C10: 10 t ha−1; C15: 15 t ha−1; and three foliar frequencies of banana pseudostem sap (BPS), WFS: without application; 2TFS: two; and 3TFS: three times. The treatments were repeated three times, followed by the factorial completely randomized block design. Increasing the dose of compost and foliar sap improved corn growth, yield, and quality. Compared to chemical fertilizers, soil amendment with BPC significantly improved N (7.31%) and P (19.4%) uptake, corn yield (10.6%), and 11.4%, biomass in the 15 t ha−1 compost-treated pot. Similarly, the three foliar sprays of BPS separately increased on average by 8% and 6.5% of cob yield and biomass, respectively over the non-spraying treatment. In contrast, the interaction effects of BPC (15 t ha−1) and foliar spray of BPS (three times) also significantly increased K, Ca, and Mg uptake by 120, 844, and 1823%, respectively, compared with those of the control. Consequently, the phenolic and total sugar content increased by 16.21% and 7.28%, respectively in BPC (15 t ha−1) related to the response of sole chemical fertilizers. Banana pseudostem-based compost at the rate of 15 t ha−1 with three foliar sprays of banana pseudostem sap could increase the productivity and quality of sweet corn in acidic soil.
期刊介绍:
The Journal of Soil Science and Plant Nutrition is an international, peer reviewed journal devoted to publishing original research findings in the areas of soil science, plant nutrition, agriculture and environmental science.
Soil sciences submissions may cover physics, chemistry, biology, microbiology, mineralogy, ecology, pedology, soil classification and amelioration.
Plant nutrition and agriculture submissions may include plant production, physiology and metabolism of plants, plant ecology, diversity and sustainability of agricultural systems, organic and inorganic fertilization in relation to their impact on yields, quality of plants and ecological systems, and agroecosystems studies.
Submissions covering soil degradation, environmental pollution, nature conservation, and environmental protection are also welcome.
The journal considers for publication original research articles, technical notes, short communication, and reviews (both voluntary and by invitation), and letters to the editor.
