Influence of intercropping systems on soil health, productivity and quality of guava (Psidium guajava l.) in Eastern India

Abstract

ABSTRACTA guava based intercropping systems comprising of nine intercrops such as mango ginger, turmeric, tomato, cowpea, frenchbean, ragi, niger, upland paddy and control (without intercrop) was conducted to study the influence of various intercropping systems on plant and soil health of guava orchard. The results revealed that guava + cowpea system showed significant improvement in bulk density, electrical conductivity, water holding capacity, organic carbon content and pH of orchard soil. The guava + cowpea system also recorded significantly maximum available nitrogen and potassium content in the soil, whereas the maximum available phosphorus content were obtained in guava + mango ginger system. The nitrogen, phosphorus, and potassium (N, P and K) content of guava leaf were found to be maximum under the guava + cowpea system. The fruit yield of guava was recorded highest in guava +cowpea intercropping system. However, the total soluble solids (TSS) and acidity of fruits were not affected by the intercropping systems.
