Abstract
New chelated Zn formulations TNAU Zn EDTA (9.7 % Zn) and TNAU Zn citrate (9.0 % Zn) were developed and tested in comparison with ZnSO4 and commercial Zn EDTA in a field experiment with maize crop conducted during 2018-19 at Tamil Nadu Agricultural University, Coimbatore. The experiment was laid out in Randomized Block Design with treatments control (NPK alone), soil application of 7.5 kg Zn ha-1 as ZnSO4, 0.75 and 1.5 kg Zn ha-1 as TNAU Zn EDTA, TNAU Zn citrate and commercial Zn EDTA, foliar spray of 0.5 % ZnSO4, TNAU Zn EDTA, TNAU Zn citrate and commercial Zn EDTA thrice on 30, 40 and 50 days after sowing (DAS). Significantly highest grain yield (7158 kg ha-1) and stover yield (12741 kg ha-1) were recorded in the treatment foliar spray of 0.5 % TNAU Zn EDTA which remained on par with the application of 1.5 kg Zn ha-1 as TNAU Zn EDTA, foliar spray of 0.5 % TNAU Zn citrate and foliar spray of 0.5 % commercial Zn EDTA. Foliar spray of 0.5 % TNAU Zn citrate registered grain yield of 6962 kg ha-1 and stover yield of 12115 kg ha-1. Significantly highest grain Zn content and uptake of 32.4 mg kg-1 and207 g ha-1 respectively were observed in the treatment foliar spray of 0.5% TNAU Zn citrate. Stover Zn content (36.5 mg kg-1) and uptake (436 g ha-1) were significantly highest with foliar spray of 0.5% TNAU Zn EDTA. Percentage yield increase due to foliar spray of 0.5 % TNAU Zn EDTA and 0.5 % TNAU Zn citrate formulations were 12.3 and 9.17 % respectively over ZnSO4 foliar spray. The treatments foliar spray of 0.5 % TNAU Zn EDTA and 0.5 % TNAU Zn citrate thrice on 30, 40 and 50 DAS recorded higher grain and stover yield as well as Zn content and Zn uptake over all other treatments.
