Comparative effects of bio-compost and compost on growth, yield and nutrients content of pea and wheat plants grown on sandy soils

Abstract: Two field trials were conducted on a sandy soil at Ismailia Agriculture Research station to evaluate response of both pea and wheat plants to added Bio-compost (rice straw compost inoculation with some microorganisms i.e., Azotobacter Chroococcum ,Bacillus Megaterum and Bacillus Circulars) , compost I (rice straw compost and inoculation the soil with the same microorganisms) compared with compost II rice straw compost (without inoculation) and mineral fertilizers (N,P and K).
The agronomic yield component were recorded and the chemical analysis of soil and plants for both pea and wheat at flowering stage (shoots) and harvest stage (straw, seeds or grains), respectively, were done. Total count of three types of bacteria were determined in soil samples at two growth stages as well as dry weight and number of nodules were recorded for pea plants.
Obtained results revealed that application of both Bio-compost and compost I increased the amount of organic matter content, available N (NH4 ,NO3) , P (P2O5) and K (K2O) as well as EC and pH values decreased in soil samples at both growth stages of pea and wheat plants. Data also show that compost I treatments were superior in this studied parameters as compared to Bio-compost and compost II.
Nitrogen , phosphorus and potassium uptake along with crude protein in seeds or grains were increased in mineral fertilizers treatments , compost I and Bio-compost as compared to compost II.
On the other hand, data also show that added of compost I as a single inoculums were the best results in the numbers of microorganisms as compared to different treatments in two stages of pea and wheat plants. .In addition to that compost I treatment increased the nodulation status of pea plants, but the highest increased in dry weights and numbers of nodules were recorded when used rice straw compost and inoculation the soil with Azotobacter Chroococcum .This may be suggest the more suitability of added rice straw compost and inoculation the soil with bacteria as compared to Bio-compost and /or compost II fertilizers for both pea and wheat plants
