“…This genetic and physiological variation leads to release of more root exudates and secondary plant metabolites near rhizospheric zone which accelerated microbial diversity. This result was in conformity with that of Purohit et al, 2019.…”

Field experiment was carried out during 2018 and 2019 in a rice-green gram cropping system to study the effect of phosphorus (P) management in kharif rice under acidic Alfisols of Odisha, India. The experiment was conducted in split-plot design with three replications. Four main plots viz., P1-100% of soil test dose (STD) for P as basal to rice, P2- 100% of STD for P to both the crops, P3-50 % of STD for P to rice and 100% of STD for P to green gram, P4 -100% of STD for P to both the crops applied to green gram were allotted to the main plots and three rice varieties viz., V1-Mandakini, V2-Lalat and V3- Pratikhya were considered in the sub plots. Application of 100% STD for P to both the crops (P2) resulted in the highest grain and straw yield (3981 and 4715 kg ha-1, respectively). Rice variety Pratikshya maturing in 145 days produced the highest grain and straw yields of 3808 and 4399 kg ha-1, respectively. The grain quality parameters of rice like protein content (6.75 %), amylose content (20.36 %) and alkali value (4.60) were found highest in P2 which was significantly different from other P management practices. Rice variety Pratikshya produced a better quality grain like protein (6.63 %), amylose (20.28 %) and alkali value (4.56). Significantly highest total chlorophyll content (4.61 mg g-1 fresh leaves) was also observed with P2 among the P management practices and a value of 4.46 mg g-1 fresh leaves chlorophyll content was recorded in rice variety Pratikhya. Microbial biomass carbon increased up to 30 days after transplanting (DAT) and decreased thereafter up to 45 DAT irrespective of phosphorus doses and rice varieties. The soil dehydrogenase activity was increased due to application of different doses of phosphorus and rice variety irrespective of growth stages. P uptake by rice was estimated highest with P2 (100% of STD for P to both the crops) and cv. Pratikhya responded better among the varieties.

“…The application of organics increased the dehydrogenase activity due to degradation of added materials which provides intra and extracellular enzymes and increase microbial activity in the soil [27,28]. The dehydrogenase activity of organic management soil was more than conventional management [29,30].Liming of acid soil enhanced the dehydrogenase activity of soil by creating a congenial environment for microbial growth [31] The finding of this experiment was also agreed with the findings of [12,32,33].…”

The present work is a follow-up study to identify the effects of nine years long-term integrated nutrient management practices on soil microbial activities in a cereal-based cropping system which was initiated in 2010. The microbial activities like microbial population and enzyme activities were estimated at three different soil depths; 0-15 cm, 15-30 cm and 30-45 cm, in response to different treatment regimes of inorganic fertilizers, organic manures, biofertilizers, and lime. The results identified a decreasing trend in the microbial population and enzyme activity with increased soil depth. Of all the treatment regimes, the maximum enhancements of dehydrogenase and urease activities were observed when there was a combined application of lime with inorganics and organic manure. Additionally, this treatment also increased the bacterial population while decreasing the fungal and actinomycetes population in the soil. The increased soil microbial activities in this treatment can be attributed to the role of organic manures.

“…The dehydrogenase activity measured in this study increased from sowing to 60 DAS in summer and kharif maize and declined towards harvest. Similarly, [18] revealed that the dehydrogenase activity was maximum at the panicle initiation stage and thereafter it decreased in rice in acidic sandy soils of Bhubaneswar, India.…”

An experiment was conducted at Zonal Agricultural and Horticultural Research Station, Hiriyur with four different nutrient management approaches during 3 consecutive years 2019-20, 2020-21 and 2021-22. The experiment consists of 4 treatments, viz., T1 – Natural farming - Seed treatment with Beejamrutha + Ghana jeevamrutha @ 1000 kg ha-1 before sowing + Jeevamrutha @ 200 L ha-1 @ 15 days interval + mulching at 30 DAS; T2 – Organic farming - Seed treatment with Rhizobium + PSB + N equivalent basis of vermicompost; T3 – Package of Practice – Recommended dose of N, P2O5, K2O and FYM; T4 – Farmers practice - FYM @ 7 t ha-1 and 45: 115 kg ha-1 N, P2O5, respectively in a randomized complete block design (RCBD) with 5 replications. The results revealed that the application of organic manures such as vermicompost and FYM and concoctions like jeevamrutha and ghanajeevamruta for 3 years has improved soil biological properties in both seasons. Treatments varied significantly among different nutrient management approaches with respect to dehydrogenase, urease, phosphatase and arylsulfatase activity in the rhizosphere soil of the summer and kharif maize. Significantly higher enzyme activities were noticed in organic farming treatment followed by package of practice and natural farming treatment. The lowest activities were observed in farmers practice treatment. Similarly, microbial biomass carbon, nitrogen, phosphorus and sulphur were highest in organic farming treatment and lowest in farmers practice treatment.
