“…Besides plant protection, these smart NPs are extensively used to regulate the physiological process. For example, SiO 2 NPs (silicon dioxide NPs) elevates seed germination rate in Lycopersicon esculentum [ 71 , 72 ], chitosan-polymethacrylic-NPK increase biomass, nutrient uptake and antioxidant enzymes in Phaseolus vulgaris [ 73 , 74 ], Au-NPs (gold NPs) promotes seed germination, seedling growth, enzymatic activity and nutrient uptake in Zea mays [ 75 , 76 ], SiO 2 -NPs improve uptake of NPK, increase enzymatic activity and seed germination rate in Hyssopus officinalis and Z. mays [ 77 – 79 ], chitosan-CuNPs (copper NPs) enhance seed germination, activation of α-amylase, protease and activity of various antioxidant enzymes in Z. mays [ 2 , 80 , 81 ], chitosan-ZnNPs (zinc NPs) increase accumulation of zinc content and defense enzymes in Triticum durum [ 82 , 83 ], chitosan-γ-polyglutamic acid-gibberellic acid NPs promotes seed germination, root development, leaf area, hormonal efficiency, extracellular enzymes and nutrient efficiency [ 83 , 84 ], Chitosan-polymethacrylic acid-NPK NPs promotes protein content and nutrient uptake [ 74 , 85 ], ZnO-NPs (zinc oxide NPs) increase activity of catalase (60.7%), superoxide dismutase (22.8%) and nutrient acquisition [ 86 , 87 ], CeO 2 -NPs (cerium oxide NPs) enhance seed germination and vigour, enzymatic activity and nutrient uptake in Spinacia oleracea and Z. mays [ 88 – 91 ], AuNPs increase chlorophyll content and antioxidant enzyme activities in Brassica juncea [ 92 ] and TiO 2 NPs (titanium oxide NPs) enhance chlorophyll content, nutrient uptake, activity of Rubisco and antioxidant enzymes in S. oleracea and Cicer arietinum [ 89 , 93 ] (Table 1 ).…”

Conventional agriculture solely depends upon highly chemical compounds that have negatively ill-affected the health of every living being and the entire ecosystem. Thus, the smart delivery of desired components in a sustainable manner to crop plants is the primary need to maintain soil health in the upcoming years. The premature loss of growth-promoting ingredients and their extended degradation in the soil increases the demand for reliable novel techniques. In this regard, nanotechnology has offered to revolutionize the agrotechnological area that has the imminent potential over conventional agriculture and helps to reform resilient cropping systems withholding prominent food security for the ever-growing world population. Further, in-depth investigation on plant-nanoparticles interactions creates new avenues toward crop improvement via enhanced crop yield, disease resistance, and efficient nutrient utilization. The incorporation of nanomaterial with smart agrochemical activities and establishing a new framework relevant to enhance efficacy ultimately help to address the social acceptance, potential hazards, and management issues in the future. Here, we highlight the role of nanomaterial or nanocomposite as a sustainable as well stable alternative in crop protection and production. Additionally, the information on the controlled released system, role in interaction with soil and microbiome, the promising role of nanocomposite as nanopesticide, nanoherbicide, nanofertilizer, and their limitations in agrochemical activities are discussed in the present review.

“…Spinetoram was effective against Sitophilus oryzae and Rhyzopertha dominica at the application rate of 5 and 0.1 ppm, respectively, mortality of both insects was achieved after 14 days (Vassilakos et al, 2015). The use of nano-engineered alumina insecticide powders was reported by Buteler et al (2020), the powder is removed at the end of storage using a pneumatic system to avoid safety issues. Chiral amides 8i and 8j effectively control Rhyzopertha dominica, a common wheat pest (Aguiar et al, 2019).…”

Postharvest losses in food grains – A Review

Grains (cereals and legumes) are universal foods that provide calories, proteins, essential minerals and vitamins. They are essential to the nutrition of many including infants and children. Attack by insects and microorganisms, particularly fungi, during drying, storage and processing, affects the quality, safety and market value of grains. Fungal attacks before or during drying can be disastrous, the effect can persist throughout the supply chain. Postharvest grain losses pose challenges to food and nutritional security, public health, and many developing nations' economy. Postharvest storage structures and packaging materials are expected to extend the shelf life of the grains by protecting them from insects, microorganisms, environmental factors and making the microenvironment unfavorable for insect and microbial activities. Traditional storage and packaging materials are highly inefficient in this sense and are associated with quality degradation. Traditional storage and packaging materials commonly used by farmers, mostly in developing countries, include granary, crib, wooden box, gunny bag and polypropylene woven bag. Modern storage and packaging materials commonly used are metal silo and hermetic bags; they are effective but unfortunately cannot be afforded by most farmers in developing countries. The article reviewed postharvest storage management of cereals and legumes. Literature was gathered through a comprehensive literature review. The use of various traditional storage and packaging materials for grains was debated. Techniques for the prevention of postharvest losses were extensively discussed, emphasis was given to novel technology and the use of natural insecticides. Challenges associated with controlling postharvest losses were also summarised. In the end, research gaps were identified and recommendations were provided about minimizing grain contamination and postharvest losses.

“…The (Buteler M. et.al., 2020) study presents the design and the evaluation of a laboratory device, which combines mechanical motion of wheat grain and turbulent air streaming inside a positive pneumatic conveyor system [8]. The experimental results, which were conducted under laboratory conditions, show that the recovery efficiency of the prototype was equal to 98.0% ( ± 1.4) on average.…”

The article presents the design of a pneumatic screw conveyor used to move (transport) grain materials. On the basis of this design, an experimental setup was created, enabling the performance of the new conveyor belt to be investigated in the laboratory, including the power parameters. The Altivar-71 frequency converter was used in experimental studies to determine the power parameters of the pneumatic screw conveyor for the transport of grain materials. Based on the results of the experimental studies, graphs of the power characteristics of the pneumatic screw conveyor drive over the time of the transport of grain materials were obtained. By analysing the graphs obtained, it is established that the smooth operation of the conveyor belt depends on the properties of the transported material. In particular, it affects the switching frequency of the pneumatic drive, which prevents it from overloading and, therefore, premature breakdown. In addition, activation of the pneumatic actuator destroys the resulting thickening of the transport granular material. Experimental studies have also been conducted on changes in performance Q of the pneumatic screw conveyor depending on the initial values of the high-pressure air supply P.
