Abstract:

A study was carried out in the Department of Soil Science and Agrl Chemitry, College of Agriculture, Vellayani, Kerala Agricultural University to compare the respiratory and microbial activities under integrated plant nutrient system between rhizosphere and non rhizosphere in laterite soil under Integrated Plant Nutrient System. The rhizosphere and non rhizopshere samples of the test crop Okra were collected and analysed for microbial parameters and respiratory activity. The fertility index ( Enzyme activity numbe) was also worked out.Microbial count was calculated using serial dilution technique. For bacteria in the rhizosphere soil, T8 (P (50 %) as PSB enriched vermicompost + P (50%), N & K) recorded the maximum bacterial count while in the non- rhizosphere soil, highest value of bacterial colonies was recorded by T12 (P (75%) as PSB enriched vermicompost + P (25%), N & K). Treatment T9 (NPK (50 %), PGPR mix-1 enriched vermicompost + N, P & K (50%) recorded maximum number of fungal colonies in rhizosphere soil and actinomycetes in the non rhizosphere soil. In the non rhizosphere soil, maximum number of fungal colonies was observed with the application of T9 and T13. Treatment T13 (N, P, K, (75 %) as PGPR mix-1 enriched vermicompost + N, P & K (25 % )recorded the highest values for actinomycetes in the rhizosphere soil. The enzyme activity number is found to be higher than the rhizosphere soil.It is understood that rhizosphere, the soil adjacent to plant roots is significantly different from bulk soil in chemical, biological and microbiological properties
