Assessment of Herbicidal Mixtures for Effective Weed Management in Blackgram under Irrigated Conditions of Pudukkottai District

An On Farm Trial was conducted to assess the herbicide for effective weed management in irrigated black gram in Pudukkottai district during the year 2022-2023 through ICAR-Krishi Vighyan Kendra, Vamban, Pudukkottai. Five farmer’s fields were selected in the Mangalakoil village of Karambakudi block. The technological options adopted in the On Farm Trial were TO1: EPOE application of quizalofop ethyl @ 50 g a.i/ha and imazethapyr @ 50 g a.i /ha on 15 – 20 DAS, TO2: Sodium Acifluorfen 16.5% + Clodinafop- Propargyl 8% EC (ready mix) at 1000 ml/ha and Farmers practice: Two hand weeding on 15 and 30 DAS. Herbicide dose was calculated and were applied as per the treatment schedule in the farmer’s field and observation on weed density was taken at periodical intervals. Weed dry weight and weed control efficiency were calculated. Outside the OFT plots, un weeded control plot was maintained for taking observation on weed count and to calculate weed control efficiency. During the cropping period one off campus training at Mankalokoil village was conducted to enrich the knowledge among farmers on the use of early post emergence herbicide for the control on weeds and critical technologies to be followed in blackgram. From the average yield obtained and economics worked out, it was concluded that Early post emergence application of Sodium Acifluorfen 16.5% + Clodinafop- Propargyl 8% EC (ready mix) at 1000 ml/ha is recommended to the farmers of Pudukkottai for the control of broad spectrum of weeds with higher yield and economic returns in blackgram

Reconfigurable MIMO Antenna for 5G Communication Applications

The current article presents the design of reconfigurable multiband antenna fed by coplanar waveguide feeding using commercially available pin diodes. Multiple input multiple output structure is proposed to reduce the polarization diversity related issues. The designed antenna operating in the wideband with coverage in 5G band. The proposed model is showing huge bandwidth of almost 10 GHz with peak realized gain of 6.8 dB. Good impedance characteristics in the operating band with Omni directional radiation makes this model suitable for future communication applications.</jats:p

Approaches and methods for individual performance assessment in information systems projects

Organizations have to manage human resources effectively, as these are fundamental to their success. Indeed, it is widely recognized that human resources have a direct influence in the performance of organizations. Therefore, organizational success is highly dependent on an adequate management of human resources. In this context, the performance assessment of people is crucial, as it is an important process for implementing efficient and effective motivational and rewarding systems. However, in the case of information systems projects, there is not much research work focused on human resources performance evaluation. This chapter aims to contribute to fill this gap by reviewing several approaches and methods for performance assessment, which can be applied to information systems projects. The presented approaches and methods are focused on personality, behaviors, comparison, and outcomes/results
