Assessing the Influence of Nano Urea on the Growth and Yield of Irrigated Wheat (Triticum aestivum L.) Crop

Wheat (Triticum aestivum L.) is one of the world's most essential cereal crops, serving as a staple food for a significant portion of the global population. In the pursuit of achieving higher yields in contemporary agriculture, the use of chemical fertilizers poses an increased environmental risk. However, the application of Nano urea offers a potential solution to mitigate this risk to a certain extent. To address this objective, a field experiment was conducted during the Rabi seasons of 2022-2023 at the A trial was executed in the rural area of Kanpur district of Mandhana, located 10 km from Kanpur in Uttar Pradesh, during the Rabi season of 2022-23. The experimental design involved two main factors: Factor-1 Nitrogen (at 50%, 75%, and 100% levels) and Factor-2 Foliar Spray (at one time Nano urea and two time Nano urea, with 4 ml/l). A control group was included, and the experiment was laid out in a Randomized Block Design (RBD) with 13 treatments in three replications. The results indicated that the combination of 100% nitrogen along with a foliar spray of 4 ml/L Nano urea had a significant positive impact on growth, yield, and various yield parameters. Treatment 6 demonstrated the highest values for plant height (95.66 cm), Dry matter accumulation (1014.09 g m-2), number of tillers m-2 (417.44), Leaf area index at 90 DAS (4.85), effective ear head per (m-2) (282.66), grains per ear head (65.75), test weight (48.52 g), grain yield (46.15 quintals/ha), and straw yield (57.92 quintals/ha). The study's results demonstrated a generally positive effect of combined Nano urea with traditional NPK nutrient supply on the growth and yield parameters of wheat in irrigated conditions.

Safflower (Carthamus tinctorius L.) is an important oil seed crop, essential as vegetable oil for humans and feed for livestock. The experiment was conducted in a split plot design to study the effects of foliar application of nano urea and urea on safflower growth and development. The results showed that application of 100% nitrogen in the form of urea topdressing at vegetative stage and foliar spray of nano urea twice at flowering and seed filling stages significantly improved the physiological parameters viz. plant height (cm), primary branches of safflower. The CSI, RWC, Seed yield (kg/ha), 100 seed weight (g) and hull content (%) of safflower also significantly improved with 100% N and foliar spray of nano urea twice at flowering and seed filling stages.

Foliar application of nano urea improves the nutrient uptake by the crop through its slow and controlled release of nutrients. It also helps in reducing environmental pollution due to leaching of fertilizers.

Comparative Evaluation of Neem-coated Urea and Nano Urea on the Growth and Physiological Attributes of Finger Millet (Eleusine coracana L. Gaertn)

An experimental study was conducted to investigate the effects of nitrogen fertilization on finger millet, with Significant nutrient losses, especially for nitrogen (N) fertilizers, occurring when chemical fertilizers are directly incorporated into the field. These losses primarily result from leaching and volatilization processes under this practice, crops tend to utilize only a fraction of the applied N fertilizers, typically ranging from 30 to 40%. These observations highlight the inefficiency of traditional fertilizer application methods and the need for improved nutrient management strategies to maximize nutrient utilization by crops and minimize environmental impacts. The study was conducted in Karunya Institute of Technology and Sciences Coimbatore. The experiment was laid out in Randomized block design (RBD) with seven treatments and replicated three times. The results of the study demonstrated that the treatment combining 50% neem-coated urea (NCU) and 50% nano urea (NU) in addition to phosphorus (P) and potassium (K) (T5) exhibited exceptional performance compared to the other treatments. This particular treatment displayed significant outcomes, including an increase in plant height of (93.7cm), improved leaf area index (3.95), greater total dry matter production (6443 kg/ha), a higher number of tillers (161.24/m2), increased productive tillers (94.2/m2), enhanced grain yield (4350 kg/ha), higher straw yield (5829 kg/ha), improved gross returns (143313 Rs/ha), a net return of (Rs. 88,247/ha), and a benefit-cost ratio of 2.60. On the other hand, the application of (75% Neem coated urea + 25% Nano urea + P and K) can be considered as a second option for obtaining higher yield and economics of growing finger millet.
