The increasing level of soil degradation has made soil biological health an important aspect of managing the problems of RWCS through understanding the role of microbes in enhancing soil health and by increasing the adoption of conservation agriculture-based practices. Our two-year study revealed that soil biological health, as measured by soil acetylene reductase activity (ARA), soil chlorophyll, microbial biomass carbon (MBC), soil dehydrogenase enzyme activity, and soil alkaline phosphatase activity (APA), was significantly impacted by the rice and wheat cultivation methods. The system of rice intensification (SRI) and zero tillage wheat (ZTW) system had significantly higher values for all the studied microbial parameters. The application of Anabaena-Pseudomonas biofilm formulation along with 75% recommended dose of nutrients (RDN) (90 kg N/ha and 19.35 kg phosphorus (P/ha) significantly improved all studied microbial parameters in both rice and wheat. The microbial properties such as dehydrogenase enzyme activity, alkaline phosphatase activity and microbial biomass carbon (MBC) had significantly higher values in treatment with RDN over 75% RDN indicating the role of optimal fertilization in soil biological health maintenance. A significant improvement in ARA and soil chlorophyll in inoculated treatment showed superior performance of inoculated microbes over inherent soil microbes in nitrogen fixation. The study of a combination of different rice and wheat cultivation methods and their influence in the long run on soil biological health in RWCS emphasizes the need for soil biological health maintenance considering its significant role in the system’s sustainability.","PeriodicalId":17022,"journal":{"name":"Journal of Rice Research and Developments","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84872606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dhaincha (Sesbania aculeata), Cowpea (Vigna unguiculata), and urd bean (Vigna mungo) were grown along with direct seeded rice, uprooted and used as a green mulch, 25 days after seeding. Six varietal trials were conducted under aerobic conditions during the 2017 and 2018 wet seasons in which the entries RP 6191-HHZ1-Y4-Y1-Y1 (6.90 t ha-1), PA 6129 (hybrid) (6.45 t ha-1), RP 6273-HHZ4-DT3LI1-LI1 (6.10 t ha-1), CR Dhan 201 (5.185 t ha-1), US 380(hybrid) (5.28 t ha-1), NVSR 2107 (4.73 t ha-1), IIRRH 124 (hybrid) (4.70 t ha-1) with early maturity were found promising. In varietal trials, intermediate plant height (100 to 110 cm), non-lodging and high yield (>4.0 t ha-1) were major criteria for selection. Two to three irrigations were applied as per the requirement. Naveen variety under aerobic conditions produced maximum yield with 125 kg N per hectare in both years.

Growth parameters like plant height, tillers per plant, yield attributes viz; length of panicle, number of filled and unfilled grains per panicle, test weight, straw yield, and harvest index were compared under both conventional and SRI methods. Subplots comprising four nitrogen management practices like control (N1),100% organic (N2), 50% organic+50% inorganic (N3) 100% inorganic (N4) were taken. The maximal yield was recorded in SRI (5265 kg ha-1) than conventional cultivation i.e., Normal Transplanting (4168 kg ha-1). Among the nitrogen management practices 50% inorganic + 50% organic treatments (N3) showed better performance when compared to 100% inorganic (N4), followed by 100% organic (N2) and control (N1). The pooled analysis of grain yield was observed to be highest in the N3 treatment (5551 kg ha-1), followed by N4 (5185 kg ha-1), N2 (4988 kg ha-1), and control N1 (3142 kg ha-1).

A total of 46 cultivars including hybrids (10), High yielding varieties (HYVs) (28) and elite cultures (8) were tested. Data pooled over years and seasons indicated that SRI was significantly superior in terms of number of tillers, number of panicles per square meter, days for 50% flowering and grain yield with low inputs viz; energy, man power and irrigation. Hybrids, HYVs and elite culture recorded a grain yield of 6.54 t/ha, 5.65 t/ha and 5.50 t/ha under SRI as compared to 5.13, 4.59 and 4.58 t/ha, respectively under NTP, thereby indicating that SRI excelled NTP in grain yield. Pooled data of six seasons, three years among the cultivars indicated that SRI recorded higher grain yield (5.90 t/ha) over NTP (4.77 t/ha) with mean percent grain yield increase of 23.4%. Intensification method was also promising over conventional transplanting in terms of energy use efficiency (SRI 10.17% over NTP 6.20%) and economy parameters (B:C ratio 2.0 in SRI and 1.20 in NTP).
