“…When the fertilizer dose was reduced, it fastened the maturity due to less availability of nutrient support to the crop plant. A similar finding was reported that the different NPK levels significantly affected the days to maturity by Handayati and Sihombing (2019). The head diameter of the sunflower also significantly differed among the hybrids and fertilizer levels.…”

The present study aimed to assess the high-yielding sunflower hybrids responding to various fertilizer levels. The experiment was conducted . with treatments that includes five genotypes in factor A (H1: COH 3, H2: DRSH-1, H3: KBSH-74, H4: KBSH-44, and H5: CO 2) and three fertilizer levels in factor B (F1: 50 percent RDF, F2: 100 percent RDF and F3: 150 percent RDF) in a three replications factorial randomized block design The study revealed that plant height and days to maturity of sunflower showed significant differences among the hybrids and different levels of fertilizer. Days to 50 per cent flowering significantly differed among the hybrids and not by the NPK level. The newly developed sunflower hybrid COH 3 recorded a higher yield (2194 kg ha-1) with high oil content (39.8 percent) and oil yield of 875 kg ha-1. Hybrid COH 3 registered a higher gross return of Rs. 70,208/- per ha with a net return of Rs.28,202/- and a cost-benefit ratio of 1.60. Among fertilizer levels, the 150 percent RDF recorded the highest yield, which was on par with the 100 per cent RDF. In monetary terms, rupee return per rupee investment was greater than 100 percent. As a result, in the Tamil Nadu region, sunflower hybrid COH 3 cultivation with 100% fertilizer, i.e., 60:90:60 kg NPK ha-1, was shown to be economical with better oil yields.

“…A study was conducted in the Haryana state of India with a total area of 1225 acres and found that an average yield was recorded 5.35% higher in wheat, 24.24% in sesame and 8.4% in mustard by applying nano fertilizers of nitrogen and zinc along with the organic farming practice ( Kumar et al., 2022 ). If N nano fertilizer was applied at the rate of 60 kg ha −1 on Sunflowers would produce the highest seed yield (17.6%) and oil yield (28.7%) as compared to conventional N fertilizer ( Handayati and Sihombing, 2019 ). Half doze of HA-N nano fertilizer shows a similar effect of urea in rice ( Bhavani et al., 2020 ).…”

Drought is a leading threat that impinges on plant growth and productivity. Nanotechnology is considered an adequate tool for resolving various environmental issues by offering avant-garde and pragmatic solutions. Using nutrients in the nano-scale including CaP-U NPs is a novel fertilization strategy for crops. The present study was conducted to develop and utilize environment-friendly urea nanoparticles (NPs) based nano-fertilizers as a crop nutrient. The high solubility of urea molecules was controlled by integrating them with a matrix of calcium phosphate nanoparticles (CaP NPs). CaP NPs contain high phosphorous and outstanding biocompatibility. Scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and X-ray diffraction analysis (XRD) were used to characterize the fabricated NPs. FE-SEM determined no areas of phase separation in urea and calcium phosphate, indicating the successful formation of an encapsulated nanocomposite between the two nano matrices. TEM examination confirmed a fiber-like structure of CaP-U NPs with 15 to 50 nm diameter and 100 to 200 nm length. The synthesized CaP-U NPs and bulk urea (0.0, 0.1% and 0.5%) were applied by foliar sprays at an interval of 15 days on pre-sowed VL-379 variety of finger millet (Eleusine coracana (L.) Gaertn.), under irrigated and drought conditions. The application of the CaP-U NPs significantly enhanced different plant growth attributes such as shoot length (29.4 & 41%), root length (46.4 & 51%), shoot fresh (33.6 & 55.8%) and dry weight (63 & 59.1%), and root fresh (57 & 61%) and dry weight (78 & 80.7%), improved pigment system (chlorophyll) and activated plant defense enzymes such as proline (35.4%), superoxide dismutase (47.7%), guaiacol peroxidase (30.2%), ascorbate peroxidase (70%) under both irrigated and drought conditions. Superimposition of five treatment combinations on drought suggested that CaP-U NPs at 0.5 followed by 0.1% provided the highest growth indices and defense-related enzymes, which were significantly different. Overall, our findings suggested that synthesized CaP-U NPs treatment of finger millet seeds improved plant growth and enzymatic regulation, particularly more in drought conditions providing insight into the strategy for not only finger millet but probably for other commercial cereals crops which suffer from fluctuating environmental conditions.

“…Additional data indicates that nanoparticles (NPs) may enter epidermal and cortical cells through the cell wall and collect evenly or in clusters in the endodermis [124]. When nitrogen nano-fertilizer is administered at a rate of 60 kg ha1, it has been shown that it results in the greatest seed production (17.6%) and oil production (28.7%) when compared to conventional nitrogen fertilizer treatments [126]. It was revealed that a highly effective phosphorus (P) nanofertilizer increased the growth rate and seed production of soybean substantially (Glycine max).…”

The major issues influencing human health in developing countries is the nutrient deficiency in different field crops. Several problems with the low efficiency of using the traditional chemical fertilizers by plants, despite there are more development in agricultural cultivation. Therefore, biofortification with nano-fertilizers and nano-biostimulants have been proposed as potential ways to enrich diets with nutrients. Organic fertilizers confront the issue of extending the duration of nutrient release and decreasing mineral content; however, inorganic fertilizers suffer from volatilization and loss of leaching. Nanotechnology’s application in agriculture has enormous promise to address these issues. The use of nanoparticles in biofortification of wheat is gaining traction due to their capacity to provide the optimal amount of fertilizer at the optimal time, hence reducing environmental concerns, facilitating nutrient uptake and absorption, and increasing grain production and profitability. Wheat is a major field crop that can solve with applying nano-biofortification the problem of malnutrition and nutrient deficiencies in humans. Although numerous research experiments on nano-bio-fortification of wheat plants have been conducted, this review article summarizes the benefits and results of nano-bio-fortification for grain maximization through a comprehensive review of nanomaterials and fertilizers and their effective role in bio-fortification and grain yield maximization. Moreover, current trends in the usage of many nanotechnology-based biofortification methods for wheat production were highlighted. Several methods for wheat improvement, including macro and micronutrient supply, are reviewed in more details. Understanding several features of the safe use of nanoparticles and their future prospects may assist in their effective use in terms of economics and nutritional needs after the usage of nano-fertilizers and nano-biostimulants in biofortification and wheat grain yield maximization.
