(Springer Singapore, 2018) M.L. Dotaniya; N.R. Panwar; V.D. Meena; C.K. Dotaniya; K.L. Regar; Manju Lata; J.K. Saha
Heavy metal pollution is emerging with time and reduces the chances of healthy food production from natural resources. Heavy metals are toxic in nature and caused various types of malfunction in plant, animal, and human bodies. Some heavy metals are essential for plant growth in lower level; but higher level shows toxic effects on plant growth. Heavy metals are also having carcinogenic, muta- genic, malfunctioning, and teratogenic and mostly affected the neurological, liver, and kidney function. Increasing population with higher pace needs food from the fixed-cultivated land. It is a great challenge for the researcher and policy-maker in one side mitigating the food crisis without contamination of natural resources. The waste generation per capita increased with tremendous rate and vice versa freshwa- ter resources shrinking. The needs of management for wastewater (WW) or metal-contaminated soil for the sustainable crop production in most of the developing countries. Various heavy metal remediation techniques are used for the removal of metals from environment. Among the techniques, bioremediation techniques are eco-friendly in nature, in situ, low cost, and energy saving. Phytoremediation tech- niques are green techniques with a wider scope of contamination removal. The cli- matic changes are also affecting the crop and soil production capacity; it needs more research in abiotic stress. © Springer Nature Singapore Pte Ltd. 2018. All rights reserved.

(Springer Singapore, 2019) Kirti Saurabh; Rakesh Kumar; J.S. Mishra; Hansraj Hans; Narendra Kumawat; Ram Swaroop Meena; K.K. Rao; Manoj Kumar; A.K. Dubey; M.L. Dotaniya
Rice-wheat cropping system (RWCS), one of the prominent agricultural production systems, at an area of ~26 M ha is confined to the Indo-Gangetic Plains (IGPs) in South Asia and China. Crop residues obtained from field crops are essential sources of nutrition and organic carbon (40% of total dry biomass constituted by C) for the next crops, and hence they not only increase the agricultural productivity but also are responsible for the better quality of soil, water, and air. Perhaps the most important challenge facing exhaustive RWCS in all regions of the world is effective management of post-harvest crop residues. Disposal of wheat residue is easy as it can be used to feed animals. However, due to the presence of high silica content, rice residue is usually burned. Residue burning is the main method of disposal in areas under combined harvesting in the IGPs of eastern India as it reduces cost. However, burning of crop residue (CR) is not eco-friendly as it results in fast degradation of soil organic matter and nutrients and increased CO2 emission creating intense air pollution as well as global warming. Therefore, exploitation of CR is a crucial element for a sustainable production system, and it has generated much interest in the recent years by reducing the consequence of residue burning and increasing the soil organic matter (SOM) and the nutrient-supplying capacity. CR retention infield can be considered a key element in promoting soil health with increased physical, chemical, and biological properties. In RWCS, residue management can be done by (1) wheat residue retention in rice and its residual effect in succeeding wheat crop, (2) rice straw retention in wheat and its residual impact in following rice, and (3) wheat straw retention in rice and rice straw. © Springer Nature Singapore Pte Ltd. 2020.

Plant beneficial rhizospheric microorganism (PBRM) strategies to improve nutrients use efficiency: A review
(Elsevier B.V., 2017) Vijay Singh Meena; Sunita Kumari Meena; Jay Prakash Verma; Ashok Kumar; Abhinav Aeron; Pankaj Kumar Mishra; Jaideep Kumar Bisht; Arunava Pattanayak; Muhammad Naveed; M.L. Dotaniya
Plant beneficial rhizospheric microorganisms (PBRMs) are rhizospheric microbes that are able to colonize rhizosphere and to improve plant growth, development and nutrient use efficiency (NUE) by means of a wide variety of mechanisms like organic matter mineralization, biological control against soil-borne pathogens, biological nitrogen (N) fixation, potassium (K), phosphorous (P) and zinc (Zn) solubilization and root growth promotion. Improved grain production to meet the food demand of an increasing population has been highly dependent on chemical fertilizer input based on the traditionally assumed notion of ‘high input, high output’, which results in overuse of fertilizers but ignores the biological potential of roots or rhizosphere for efficient mobilization and acquisition of soil nutrients. A very interesting feature of PBRMs is their ability of enhancing nutrient bioavailability or NUE by ∼ 20-40% with various nutrients. Although chemical fertilization is a quick method, it is not recommendable economically and environmentally, especially if overused. Several PBRMs species have been characterized as biological N-fixer, P, K-solubilizing microorganisms while other species have been shown to increase the solubility of micronutrients, like those that produce siderophores for iron (Fe) chelation. The enhanced amount of soluble macro- and micronutrients in the close proximity of the soil-root interface has indeed a positive effect on plant nutrition. There is a growing body of evidence that demonstrates the potential of various microbes to enhance plant productivity and yield in cropping systems. However, the molecular mechanisms underlying these phenomena, the signals involved as well as the potential applications in a sustainable agriculture approach, and the biotechnological aspects for possible rhizosphere engineering are still matters of discussion. © 2017 Elsevier B.V.
Potassium uptake by crops as well as microorganisms
(Springer India, 2016) M.L. Dotaniya; V.D. Meena; B.B. Basak; Ram Swaroop Meena
Potassium (K) is one of the essential major plant nutrients. Its importance in agriculture has increased with intensive agriculture as well as deficiency occurring in crop plants. Global population is increasing at a quantum rate, which pushes the targeted yield to higher levels for mitigating the food demand of hungry mouths. Production of more food material from limited land is a challenge for the researcher and it aggravates nutrient deficiency, due to more uptake of plant nutrients, especially K, by high-yielding crop varieties. Among plant nutrients, deficiency of K limits the crop growth and reduces the crop yield. The source of K is native or via various replenishment paths, i.e. crop residue, microbial biomass and a range of waste materials. Researchers mentioning the wide gap between the addition of K and removal during crop production are highlighting the challenge to maintain a sustainable crop yield. The nutrient balance in the soil system is also affected by the quantity of nutrient that is taken up, raising nutrient storage in the soil-plant–microbe system, and how much is recycled by crop residues. The use of potassium-solubilizing microorganisms (KSMs) can increase the K level in the soil solution and ultimately increase plant growth and development. The main mechanisms of KSMs are acidolysis, chelation, exchange reactions, complexolysis and organic acid production in the soil. K fertilizers cost much more than other fertilizers, so use of KSMs in agricultural crop production can be a sustainable option for enhancing in situ K availability from the fixed sink of agricultural soils. © Springer India 2016.

Reuse of poor-quality water for sustainable crop production in the changing scenario of climate
(Springer Science and Business Media B.V., 2023) M.L. Dotaniya; V.D. Meena; J.K. Saha; C.K. Dotaniya; Alaa El Din Mahmoud; B.L. Meena; M.D. Meena; R.C. Sanwal; Ram Swaroop Meena; R.K. Doutaniya; Praveen Solanki; Manju Lata; P.K. Rai
The availability of freshwater is limited for agriculture systems across the globe. A fast-growing population demands need to enhance the food grain production from a limited natural resources. Therefore, researchers and policymakers have been emphasized on the production potential of agricultural crops in a sustainable manner. On the challenging side, freshwater bodies are shrinking with the pace of time further limiting crop production. Poor-quality water may be a good alternative for fresh water in water scarce areas. It should not contain toxic pollutants beyond certain critical levels. Unfortunately, such critical limits for different pollutants as well as permissible quality parameters for different wastewater types are lacking or poorly addressed. Marginal quality water and industrial effluent used in crop production should be treated prior to application in crop field. Hence, safe reuse of wastewater for cultivation of food material is necessary to fulfil the demands of growing population across the globe in the changing scenario of climate. © 2022, The Author(s), under exclusive licence to Springer Nature B.V.
Role of biofertilizers in conservation agriculture
(Springer Singapore, 2016) Mahendra Singh; M.L. Dotaniya; Amit Mishra; C.K. Dotaniya; K.L. Regar; Manju Lata
In the present time, chemical fertilizers are more in practice for crop production which affected the soil and environment quality. The higher amount of chemical inputs in agricultural production system affected the sustainability of the agricultural crop production systems, increased cost of cultivation, and caused partial factor productivity decline, and maintaining the global food security and environmental quality became a daunting challenge. Indiscriminate and imbalanced use of fertilizers, mostly urea, and the poor application of organic matter to cropland have led to considerable reduction in soil health. Nowadays our agriculture has shifted to old-age practice like conservation agriculture. It is using old tool and techniques with incorporation of modern science and scientific principles. In general, biofertilizer is organic in nature containing an effective particular microorganism in a concentrated form which originated either from the plant root nodule or from the soil of the rhizosphere. Biofertilizers have emerged as potential environment-friendly inputs that are benefited for agricultural crop production system. They hold vast prospective in fulfilling the plant nutrient requirements, which are reducing the chemical fertilizer application and minimizing environmental pollution. The bioinoculants are used as a seed treatment or soil treatment, improving plant nutrient availability and finally crop growth and yield. These contain living cells of diverse types of microorganisms and have the potential to solubilize and mobilize plant nutrient elements from insoluble form through biological process and also fix atmospheric nitrogen. The adequate use of biofertilizers helps in maintaining soil quality and thus provides a low-cost approach to manage crop yield along with protecting the environment. © Springer Science+Business Media Singapore 2016.
Role of soil enzymes in sustainable crop production
(Elsevier, 2018) M.L. Dotaniya; K. Aparna; C.K. Dotaniya; Mahendra Singh; K.L. Regar
Sustainable crop production is the current focus of agricultural research across the globe. The increasing population with a higher pace creates food shortages and reduces the per capita availability of food grains, demanding food security. The soil enzymes are the mediators of organic matter decomposition and soil nutrient transformations. Their patterns of activity in relation to environmental factors and management practices help to design sustainable management practices. Enzymes are the indicator of soil biological quality, responding to soil management changes much before other soil quality indicator changes are detectable. In the dynamic climate change era, the influence of climate change on soil productivity can be assessed by monitoring soil enzyme activities as well as changes occurring in soil properties. Thus, knowledge of soil enzymes is essential to design and evaluate new sustainable crop management practices. The soil enzymes can also be exploited for many applications beyond agriculture. © 2019 Elsevier Inc. All rights reserved.

(Springer Berlin Heidelberg, 2016) M.L. Dotaniya; S.C. Datta; D.R. Biswas; C.K. Dotaniya; B.L. Meena; S. Rajendiran; K.L. Regar; Manju Lata
Purpose: Sugarcane industries are age-old industrial practices in India which contribute a significant amount of by-products as waste. Handling and management of these by-products are huge task, because those require lot of space for storage. However, it provides opportunity to utilize these by-products in agricultural crop production as organic nutrient source. Therefore, it is attempted to review the potential of sugar industries by-products, their availability, and use in agricultural production. Methods: A large number of research experiments and literatures have been surveyed and critically analyzed for the effect of sugarcane by-products on crop productivity and soil properties. Results: Application of sugar industries by-products, such as press mud and bagasse, to soil improves the soil chemical, physical, and biological properties and enhanced the crop quality and yield. A huge possibility of sugarcane industries by-products can be used in agriculture to cut down the chemical fertilizer requirement. If all the press mud is recycled through agriculture about 32,464, 28,077, 14,038, 3434, 393, 1030, and 240 tonnes (t) of N, P, K, Fe, Zn, Mn, and Cu, respectively, can be available and that helps in saving of costly chemical fertilizers. Conclusions: Application of sugarcane industries by-products reduces the recommended dose of fertilizers and improves organic matter of soil during the crop production. It can also be used in combination with inorganic chemical fertilizers and can be packed and marketed along with commercial fertilizer for a particular cropping system. That helps in reduce the storage problem of sugarcane industries by-products across the India. © 2016, The Author(s).
