Red cabbage is known as the millennium’s functional food, which has a lot of importance in our diet because of the health-promoting ingredients present in it. The current study investigated the synergistic relationship of rhizospheric-competent microbial agents (Trichoderma harzianum, Pseudomonas fluorescens, and Bacillus subtilis) in modulating the performance of red cabbage under the field conditions of Middle Gangetic Plains, India. Growth parameters were studied at three developmental stages, viz., pre-cupping, early head formation, and maturity. Our results suggested that the dual application of T. harzianum + P. fluorescens along with the 75% recommended dose of fertilizers (RDF) increased the number of leaves (24.6), leaf area (537.2 cm2 ), root length (19.8 cm), and micronutrient uptake (Fe, Mn, and Cu) by head of the crop, whereas the co-inoculation of P. fluorescens and B. subtilis along with 75% RDF enhanced plant spread (39.0 cm), earliness (95.2 days), and Zn uptake. Maximum plant height (28.7 cm) and chlorophyll (SPAD, 77.3) were recorded in 100% RDF (120:60:60 kg ha−1 ) and the combination of T. harzianum + B. subtilis along with 75% RDF, respectively. Interestingly, consortium (T. harzianum + P. fluorescens) bio-primed plants recorded about 14% higher root length in comparison to plants receiving sole fertilizers. The regression analysis revealed a significant relationship of Fe and Mn uptake with chlorophyll (SPAD) and between Zn uptake and the earliness of the crop. The present study indicated that seedling bio-priming with the dual consortium of efficient bio-agents is a viable strategy to lessen our dependence on chemical fertilizers for improving red cabbage production. © 2022 by the authors.

EFFECTS OF CHEMICAL FERTILIZER, FYM AND BIO-INOCULANTS ON NUTRIENT CONTENT, UPTAKE AND QUALITY OF WHEAT (TRITICUM AESTIVUM L.)
(Bangladesh Botanical Society, 2021) Hanuman Prasad Parewa; J. Yadav; V.S. Meena; A. Rakshit
Effects of different levels of chemical fertilizer, farmyard manure (FYM) and bio-inoculants on nutrient content, uptake and quality parameter of wheat were studied. Results indicated that increasing levels of chemical fertilizer, FYM and bio-inoculants significantly enhanced nutrient content and uptake by wheat, while quality parameters of wheat showed significant results with bio-inoculants application. Maximum N, P and K content and their uptake in grain (80.3, 11.07 and 25.29%, respectively) and straw (32.18, 7.14 and 95.92%, respectively) were noticed with 100% NPK over control. Application of FYM @ 10 t/ha significantly increased nutrient content (NPK) in grain and straw and their uptake over the control. The total N, P and K uptake by wheat were found to be maximum 80.97, 12.68 and 86.10 kg/ha, respectively with the application of FYM over control. Combined use of fertilizer levels and FYM, and combined use of fertilizer levels and bio-inoculants significantly increased the nutrient uptake by wheat. © 2021 Bangladesh Botanical Society.

(MDPI, 2022) Hanuman Prasad Parewa; Janardan Yadav; Vijay Singh Meena; Deepranjan Sarkar; Sunita Kumari Meena; Amitava Rakshit; Rahul Datta
Two-year field experiments were conducted to study the effect of different levels of inorganic fertilizers, farmyard manure (FYM), and bio-inoculants on wheat productivity and profitability. Results specified that judicious application of inorganic fertilizers, FYM, and bio-inoculants significantly increased the productivity and profitability of wheat. Data suggested that the aggregate levels of fertilizer up to 100% NPK ha−1 resulted in significant increases in all growth attributes, grain yield (+206%), straw yield (+177%), and harvest index (+7%) as compared to control. Meanwhile, plots with the application of 10 t ha−1 FYM significantly (p < 0.05) increased grain yield (+26%) and straw yield (+22%) as compared to the control. Similarly, significant enhancement in grain and straw yields was observed with the application of PGPR + VAM over no-inoculation. Results showed that the significantly higher grain and straw yield attained by application of 75% NPK fertilizer + 10 t ha−1 FYM was at par with the application of 100% NPK fertilizer alone. Further, net returns (profitability) and B:C ratio (2.37) were significantly higher with fertilization with 75% NPK + 10 t ha−1 FYM along with PGPR + VAM as compared to 100% NPK alone. Overall, it can be concluded that the combination of 75% NPK and 10 t ha−1 FYM along with PGPR + VAM represented the optimum for net return and B:C ratio and reduced (25%) dose of NPK as compared to the rest of the treatment combinations. © 2022 by the authors.
Organic interventions conferring stress tolerance and crop quality in agroecosystems during the United Nations Decade on Ecosystem Restoration
(John Wiley and Sons Ltd, 2021) Deepranjan Sarkar; Pradeep Kumar Dubey; Rajan Chaurasiya; Ardith Sankar; Shikha; Neha Chatterjee; Sabuj Ganguly; Vijay Singh Meena; Sunita Kumari Meena; Hanuman Prasad Parewa; Amitava Rakshit
Excessive use of synthetic chemicals in conventional agriculture largely degraded the agroecosystems that constitute approximately 40% of the global terrestrial ecosystems. Moreover, changing climate resulted in a substantial loss in agricultural productivity (both in quantity and in quality) mainly due to diverse abiotic and biotic stresses. This draws public awareness about depleting natural resources, viz., soil, land, and water due to unsustainable agricultural practices and equivalently concerns for food-related animal and human health risks. Modern organic agriculture has shown positive impacts in terms of food/biomass production, climate resilience, soil health, biodiversity, nutritional security, and good quality of life; and is of prodigious demand for nutrient-rich organic food products. In the ensuing decade, owing to the principal focus for the quality aspects or health benefits of organic agriculture, this review explores how organic interventions affect the nutritional value and yield quality in a production system; enable plants to adapt to adverse futuristic environmental conditions, and address the global food and nutritional security challenges. The chronological emergence, current global status, public perceptions, and key components of organic agriculture with their attached health benefits are inextricably synthesized herein. Fostering the ethos of organic agriculture under the UN Decade on Ecosystem Restoration (2021–2030) is highly imperative for agroecosystem restoration and its sustainable management. Moreover, the multidimensional paybacks of organic agriculture help in attaining important global goals and targets such as the Bonn Challenge and United Nations Sustainable Development Goals (UN-SDGs) by the year 2030. Therefore, invigorating the escalation of organic farming as a concurrent strategy of soil, land, and ecosystem restoration is the need of the hour. © 2021 John Wiley & Sons, Ltd.
Sustainable crop production and soil health management through plant growth-promoting rhizobacteria
(Springer Singapore, 2018) Hanuman Prasad Parewa; Vijay Singh Meena; Lokesh Kumar Jain; Anirudh Choudhary
Plant growth-promoting rhizobacteria (PGPR) are the heterogeneous group of soil bacteria that are inhibiting in the rhizosphere, around/on the root sur- face, which improve the plant growth directly or indirectly via production and secretion of various regulatory substances. PGPR affect plant growth and develop- ment either by releasing phytohormones or other biologically active substances, altering endogenous levels of plant growth regulators (PGR), enhancing availability and uptake of nutrients through fixation and mobilization, reducing harmful effects of pathogenic microorganisms on plants and/or employing multiple mechanisms of action. Nowadays, PGPR have received more attention for its use as a biofertilizer for sustainability of agroecosystems. Numerous studies have suggested that PGPR in an integrated nutrient management (INM) system could be used as effective sup- plements to chemical fertilizers for promoting crop yields and soil health on sus- tainable basis. In prospect to healthy and sustainable agriculture PGPR approach revealed as one of the best alternatives. © Springer Nature Singapore Pte Ltd. 2018. All rights reserved.

Plants are an important component of the ecosystem and vital for survival of human beings. As human beings need nutrition for their proper growth and development, plants also require different nutrients to complete their life cycle. Among the all essential nutrients, zinc is one of the important nutrients required not only by plants but also by human beings. Several researchers have reported the decline in zinc level of Indian soils. An approx. 47–49% of Indian soils are facing zinc deficiency, which is continuously rising up. The deficient soils are not able to supply the crop the required amount of nutrients, since soils with zinc deficiency are unable to provide an adequate amount of nutrients. The cereal crop like rice is prone to face zinc deficiency worldwide. Keeping in view such global crop issues, a greater attention is required to fulfil the zinc requirement of crop by different agronomic and plant breeding approaches. Zinc biofortification becomes one of the promising strategies to supply zinc in the crop at an optimum level. Zinc solubilization and mobilization are one of the suitable strategies to overcome zinc-deficiency issues. The chapter has emphasized on mechanism of biofortification and its challenges and limitations for adoption at ground level. © Springer Nature Singapore Pte Ltd. 2020.
