Effect of lime, organic and inorganic fertilizers on soil chemical properties and yield of Chilli (capsicum frutescens l.)

Tóm tắt

Five treatments (NT1, NT2, NT3, NT4 and NT5) of organic fertilizer (processed 10 tons cow manure ha-1), liming (3,5 tons ha-1) and three rates of inorganic fertilizer (NPK:90-60-60 kg/ha) were evaluated on soil chemical properties and yield of chilli. Significant effects of processed liming, cow manure (CM) and inorganic fertilizer (NPK) rates on nutrient were obtained. Interaction effects between lime, CM and NPK were significant. The reslts indicated that lime, cow manure in combinination with lower dose of blanced inorganic fertilizers led to increase of soil organic matter, labile soil organic matter and available phosphorus in soil, significant difference compared to control. The maximum yield 1,48 t ha-1 at NT5 was found under the combined use of 10 tons CM/ha + 3,5 tons CaO/ha + NPK. It was also observed that some of the soil chemical properties were significantly influenced with the application of different treatments of lime and CM while  total N, available P, available K and OM were significantly affected with the application of both organic and inorganic fertilizers in different combinations. The chili yield of treatments with organic manure, chemical fertilizers; lime, organic manure, chemical fertilizers, there was a significant difference compared to control treatments.The results showed that chilli yield increased significantly from 0,302 tons /ha at NT3 (only CM) to 1,48 tons/ha at NT5 (10 tons CM/ha + 3,5 tons CaO/ha + NPK).
