Pulses are gaining more important position in Indian Agriculture.But the average productivity of pulses (764 kg ha-1) is much less productive than the global average (848 kg ha-1).To increase its productivity application of important fertiliser to cowpeas during their critical growth stages is aeffective strategy to enhance their yield. Especially smart fertilizers like Nano Di-ammonium Phosphate (DAP) and Zinc Ethylene Diamine Tetra Acetic acid (Zn EDTA) are very helpful in that. Therefore, the field experiment was done in the dairy Farm, School of Agriculture and Animal Science, Gandhigram Rural Institute, Gandhigram, Tamil Nadu during January 2024 to March2024 to assess the impact of Nano DAP and Zn EDTA on growth and yield of cowpea. It was laid out in Randomized Block Design (RBD) with seven treatments under three replications. Among the different treatments, Recommended Dosage of Fertilizers (RDF) 50% Phosphorus, 100% Nitrogen (N) and potassium (K) + Seed treatment and two foliar sprays of 0.2% of Nano Di-ammonium Phosphate (DAP)+ Foliar spray of 3% Zinc Ethylene Diamine Tetra Acetic acid (Zn EDTA)(T7) achieved supremely improved growth parameters like plant height, no.of branches per plant, leaf area index, dry matter production, and yield attributes viz., pod length, no.of pods per plant , no.of seeds per pod and test weight . Further it recorded a higher seed yield,haulm yield and harvest index. The minimum value was recorded under control treatment (T1).Experimental results clearly revealed that RDF 50% P, 100% NK + Seed treatment and two foliar sprays of 0.2% of Nano DAP + Foliar spray of 3% Zn EDTA(T7) has recorded the highest yield of 1720 kg ha-1.

Nano fertilizers have emerged as promising alternative smart fertilizers to ensure high crop production and soil restoration. In this study, we aimed to synthesize an eco-friendly and feasible potassium-incorporated nitrogenous nano fertilizer using physical and chemical methods. The synthesized nano fertilizers were characterized using Carbon, Hydrogen, Nitrogen and Sulphur (CH-NS) Elemental Analyzer, Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Scanning Electron Microscopy (SEM), and Dynamic Light Scattering (DLS) techniques. Based on the results, a suitable product was selected for preliminary trials in plant nutrition.The most essential nutrients for crops are macronutrients, such as nitrogen, phosphorus, and potassium. In the chemical synthesis, the nano fertilizer was prepared by extracting nutrients from ripe banana fruit rind (peels) and leaf extracts using chitosan nanoparticles, which served as a useful matrix for loading nutrients into crops. Subsequently, the synthesized nano fertilizer was analyzed, which revealed a particle size of 293 nm and a maximum nitrogen content of 3.51% and potassium content of 4.47%. For the physical synthesis, a planetary ball mill was used, where chitosan and potassium carbonate obtained from banana peel ash were ball milled to reduce their size. The results indicated a particle size of 5308 nm; a maximum nitrogen content of 5.55% and potassium content of 3.01%. After comparing both outcomes, the fertilizer synthesized using the chemical method was chosen for analyzing its effect on plant growth. Trials with crop plants demonstrated that the growth rates of plants increased with a decrease in the dosage of the nano fertilizer. Further elaborative field trials with different crops are suggested to evolve commercial recommendations to farmers.
