Effect of mulch and irrigation levels on yield and quality of barley (hardeum vulgare l.)
(Journal of Pure and Applied Microbiology, 2016) Kiran Hingonia; Ramesh Kumar Singh; Ram Narayan Meena; H.P. Vermal; Rajendra Prasad Meena
field study was carried out at the Banaras Hindu University's Agricultural Research Farm during the rabi (dry) seasons of 2013-14 in a Randomized block design (RBD) with three replications, consisting of 9 treatments, namely, T1-(6 t/ha mulching + No irrigation), T2 (6 t/ha mulching + One irrigation at 35 DAS), T3-(6 t/ha mulching + Two irrigation at 35 DAS & 85 DAS), T4 (4 t/ha mulching + No irrigation), T5 (4 t/ha mulching + One irrigation at 35 DAS), T6 (4 t/ha mulching + Two irrigation at 35 DAS & 85 DAS), T7 (No mulching + No irrigation), T8 (No mulching + One irrigation at 35 DAS) and T9 (No mulching + Two irrigation at 35 DAS & 85 DAS). The research results indicated that amongst different mulching and irrigation levels, the treatment T3 recorded expressively higher grain yield, straw yield, quality parameters and nutrient uptake. This in turn resulted in significant improvement in grain, straw yield, biological yield and nutrient uptake in T3 over remaining mulching and irrigation levels.
Organic farming—a key to food security and agricultural sustainability
(Elsevier, 2023) Ram Narayan Meena; Kanti Meena; Mamta Choudhary
The foundation of the Indian economy is agriculture. Our nation is now able to provide food security thanks to agricultural progress and technological advancement. Each technology has advantages and disadvantages, and this improvement in agriculture has led to the unsystematic use of a huge amount of chemical fertilizers and pesticides, which have a detrimental effect on both human health and the environment. As a result, returning to our traditional farming practices—ones devoid of chemicals, pesticides, and fertilizers—is the only way to care for the land and help the soil rebuild. Given that organic farming prevents nutrient exploitation and boosts soil organic matter content, adaptation and mitigation based on this method can build on the well-established practice. Soils used for organic farming therefore hold and capture more water than soils used for conventional farming. Furthermore, organic farming increases the variety of income sources and flexibility to deal with the negative effects of climate change and variability, such as altered rainfall patterns, by incorporating highly diverse farming systems. This decreases the vulnerability of farmers to climate change and variability. This chapter summarizes the rationale, key factors for organic farming for achieving sustainability. © 2023 Elsevier Inc. All rights reserved.
Role of nanotechnology in organic agriculture
(Elsevier, 2023) Kanti Meena; N.D. Meena; Ram Narayan Meena; Mamta Choudhary; Shashi Meena; Satendra Kumar
Organic agriculture is a holistic way of production that preserves and improves agroecosystem health, including biodiversity, biological cycles, and soil biological activity. Nanotechnology is a rapidly developing field of research and application; its terminology and use are in flux. Over time, technological breakthroughs are monitored, and research indicates that nanotechnology will be the future. Organic farming is a preferable alternative to the use of chemical fertilizers and pesticides and is supported by major nations. This is true, especially about human food consumption for health benefits. Utilizing nanoparticles as nanofertilizers, nanopesticides, nano-biosensors, and nano-growth promoters, among other applications, nanotechnology provides enhanced management of organic farming. These nanoparticles can be manufactured by chemical, physical, and biological processes. Chemical and physical methods of synthesis are inapplicable to organic agriculture since they do not meet the standards of organic farming and have their challenges. Thus, the biological process, also known as the green synthesis of nanomaterials, fits the requirements of organic farming and has attracted the attention of scientists. Extracts of plant components and other microorganisms, including bacteria, fungi, and mycorrhiza, can be utilized as raw resources for the environmentally friendly synthesis of nanoparticles. The objective of the green synthesis of nanoparticles was to decrease the negative effects of nanoparticles produced by chemical synthesis. We lack the requisite toxicological and ecological expertise to accurately evaluate nanotechnologies and nanoparticle-containing substances. Each nanotechnology application should be evaluated separately, in our opinion. Positive and negative lists appear to be an efficient way to regulate the use of nanotechnology in organic agriculture. The current review addresses the green synthesis of essential organic farming elements such as nanofertilizers, nanopesticides, and nano-growth promoters, as well as their transportation methods, advantages, and disadvantages in organic farming. © 2023 Elsevier Inc.
