“…The treatment foliar spray of 0.5 % TNAU Zn EDTA (T 10 ) recorded significantly higher Zn content and control (NPK alone -T 1 ) recorded lowest Zn content. This is in agreement with the findings of Teixeira et al, (2019) who reported that Zn content and Zn uptake in the Mombasa grass was directly proportional to the rate of foliar applied chelated Zn, contributing to the yield of better quality forage. The improvement in the Zn concentration and uptake observed in this experiment comparing ZnSO4 and Zn-EDTA, is similar to that reported by Gangloff et al, (2002).…”

New chelated Zn formulations TNAU Zn EDTA (9.7 % Zn) and TNAU Zn citrate (9.0 % Zn) were developed and tested in comparison with ZnSO 4 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 ZnSO 4, 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 % ZnSO 4, 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 ZnSO 4 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.

“…Brazilian livestock needs to ally productivity and sustainability, very divergent purposes that are being demanded by the population increase, climatic changes and behavior of consumers. In this context, the discovery and use of rational technologies are essential, since the increase in the meat and milk production are only achieved with large quantities of chemical fertilizers and openings in new areas (Teixeira et al 2019).…”

The objective of this study was to evaluate the effects of strains of Azospirillum brasilense, Pseudomonas fluorescens and Rhizobium tropici on the shoot dry weight (SDW) and root dry weight (RDW) yield, N uptake and nutritive value of 'Mavuno' grass inoculated with plant growth-promoting bacteria. We evaluated the effects of inoculation with the Ab-V5 and Ab-V6 strains of Azospirillum brasilense and Pseudomonas fluorescens or coinoculation with Rhizobium tropici and Ab-V6, with and without nitrogen (N) application, as well as re-inoculations. The growth promoting bacteria + N promoted increases in SDW and RDW yield, tillers dry weight, relative chlorophyll index and N uptake. There were no effects of re-inoculation by Azospirillum brasilense, Pseudomonas fluorescens and Rhizobium tropici on nutrition, nutritive value and SDW and RDW yield, demonstrating that this technique still needs further studies with 'Mavuno' grass in the form and the correct period to be performed.

“…The edaphoclimatic conditions and the great territorial extension are factors that, since the beginning of the Brazilian livestock, define an important characteristic of this activity, to have almost the whole of the herd raised in pastures, which constitute in the most practical and economic way to produce and to feed the cattle (Sá et al 2019;Teixeira et al 2019).…”

The objective of this study was to evaluate the effects of plant growth promoting bacteria (PGPB) inoculation in Zuri guinea grass [Megathyrsus (syn. Panicum) maximus] on shoot dry weight (SDW) and root dry weight (RDW) yield, morphological compositions, number of tillers, and nutrients concentrations in SDW. The experiment was carried out under greenhouse conditions in a randomized block design consisting of eight treatments with five replicates. The inoculation with the Ab-V5 and Ab-V6 strains of Azospirillum brasilense and Pseudomonas fluorescens or co-inoculation with Rhizobium tropici and Ab-V6, with nitrogen (N) fertilization, as well as reinoculations of the plants after cuttings were taken were evaluated. The plant growth-promoting bacteria and N fertilization promoted increases in SDW and RDW yield, tillers dry weight, relative chlorophyll index (RCI) and nutrients uptake in shoots of Zuri guinea grass. There were effects of reinoculation the PGPB by P. fluorescens in shoots, N, magnesium (Mg) and boron (B) concentration in SDW.
