    (Elsevier, 2021) Chandra, Kailash; Chand, Subhash; Khatik, C.L.; Jatav, H.S.; Kumar, Santosh; Pandey, A.K.; Sandhya; Mahla, Subhash; Omprakash; Khan, M.A.; Meena, Ramu; Kumar, Sunil; Singhal, Rajesh; Kumawat, Gaytri
    Organic seed production is need of present scenario, where every person is concern with quality food. The most compelling reason of using organically produced product is, it has less chemical impact on environment. Ensuring quality of organically produced seed is also important criteria where legal standards are checked and certificate of quality provided through various process. In order to understand all the process or organic seed, its production and certification we need to learn about organic seed, its importance, national standards for organic seed production, seed production plans, factors influencing it and many other aspects related to organic seed production. Breeding strategy for organic seed production is an important criterion to breed variety which suits in an eco-friendly cultivation of crops. In India, many farmers produce seed organically however lack of legal certification for their produce make it unable to catch the price as certified organic seed fetch. It is an important issue that everyone involved in organic seed production must know what, how and where they can get and use the input materials for this type of seed production for sustainability. Therefore this chapter include all the materials which are allowed, restricted and prohibited to use for organic seed production and certification. Key challenges and suggested organic farming practices have also been explained which will be helpful for scientific community who are approaching toward eco-friendly agriculture. Special reference has been given to Rajasthan, where from applying for organic seed product to obtain their certificate has been illustrated. � 2021 Elsevier Inc.

    Physiological and biochemical effect of elevated night temperature stress on bread wheat (Triticum aestivum L.)
    (United Arab Emirates University, 2023) Ahmad, Md. Afjal; Prakash, Pravin; Dujeshwer, K.; Srivastava, J.P.; Singh, Anil K.; Jatav, H.S.
    A laboratory experimentation was done in the Department of Plant Physiology, Institute of Agricultural Sciences, Banaras Hindu University to evaluate elevated night temperature effect in wheat (Triticum aestivum L.) to see the response in some antioxidant and biochemical parameters in two wheat cultivars viz. HUW-234 (comparatively tolerant to heat stress) and sonalika (comparatively susceptible to heat stress). A significance difference was recorded in the parameters pertaining to antioxidant system includes catalase, SOD and APX activity were found to increase substantially when the plants kept under stress conditions (250C/240C day and night temperature) than the plants kept under controlled condition (250C/150C day and night temperature). The percent increase in the antioxidant enzyme activity was found to be more in the tolerant genotype (HUW-234) than in the susceptible genotype (Sonalika). There was 23.52 % increase was reported in the catalase activity by tolerant genotype when kept under stress conditions than those kept under control. Significant reductions were reported in most of the photosynthetic and membrane parameters viz., chlorophyll �a�, chlorophyll �b� and membrane thermostability index. Similar percent reduction was reported with respect to biochemical parameters (total protein content, starch content and soluble sugar content) in the susceptible variety kept under high night temperature regime. Based on the pooled data of two-year experimentation it can be concluded that variety HUW-234 was found to be more tolerant than variety sonalika to HNT stress. � (2023), (United Arab Emirates University).

    Sewage sludge quality assessment of sewage treatment plant, Bhagwanpur, Varanasi and its safe utilization in agriculture
    (Triveni Enterprises, 2021) Jatav, H.S.; Singh, S.K.; Jatav, S.S.; Latare, A.M.; Kumar, V.; Singh, P.
    Aim: To study about the sewage sludge treatment process and its physico-biochemical analysis of sewage sludge for feasible use. Methodology: Sewage sludge samples were collected from sewage treatment plant, Bhagwanpur, Varanasi, India and processed through 2 mm sieve and further analyzed for different physical, chemical and biological analysis and compared with standard. Results: Sewage sludge consisted multielement along with a good amount of organic matter. However, sewage sludge also contained some amount of heavy metals and organic pollutants that can adversely affect soil micro-organisms. Interpretation: Sewage sludge application in soil offers essential nutrients for plant growth and decreases environmental and economic factors that restrict landfill or incineration disposal of sewage sludge. However, a careful assessment of the characteristics of soil and sewage sludge, as well as plant species to be grown, is required prior to soil application of sewage sludge. The present study will support the use of sewage sludge in agriculture to improve the soil health with a safe limit application. � 2021 Triveni Enterprises. All rights reserved.
