Abstract
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.
