Influence of Organic Manure, on Microbiological Properties of Calcareous Soil

Abstract

A long-term field experiment was started during rabi 1988-89 in calcareous soil at RAU, Pusa Farm in split plot design with NPK levels in main plots and organic sources in sub-plots. Rice and wheat as 35 th and 36 th crop were grown for present investigation. Post-harvest soil samples were analysed for bacterial, fungal and actinomycetes population. Result of study revealed a considerable increase in the population of bacteria, fungi and actinomycetes with continuous application of chemical fertilizers and organic manure alone or in combination. Bacterial population increased to a tune of 8.73, 24.60 and 28.82 per cent over control (31.50 x 10 6 cfu g -1

Initial Development of Melon when Grown in Different Concentrations of Exhausted Peat Organic Compost

“…Thus, concentrations above 15% of the exhausted compost started to compromise the development of melon in the initial phase, this availability may have been enhanced with the action of microorganisms present in the composition of the organic compost, thus increasing the cycling of nutrients and that became available in high concentrations in the substrate [16,17].…”

Production of Pepper Seedlings With Different Doses of Organic Compounds in Substrate

“…However, high levels of the compound impaired the development, once by elevating the amount of salt in the soil solution, its electrolytic and osmotic capability increase, entailing the loss of water by the seedlings (EPELDE et al, 2018;HOU et al, 2017). Therefore, concentrations above 70% harmed the development of the vegetal, that may be amplified with the presence of microorganisms, in which an elevated nutrients cycling were performed, being available in high concentrations in substrate (ZUO et a., 2018;PANDEY et al, 2017).…”

“…The higher concentration of calcium and potassium (Table 1) did not influenced the stomata functionality, since the pepper displayed a suitable growth. However, it was expected that nutrients would influence in opening and closure of stomatal, once they are directly linked to the action of calcium and potassium pumps in osmotic balance of stomatal cleft cells (PANDEY et al, 2017;FRANKS et al, 2015).…”
