A field experiment conducted at IIRR, Hyderabad with three crop establishment methods (normal transplanted rice, mechanized SRI and wet DSR) as main plot treatments and sensor based irrigation management practices (alternate wetting and drying with 5, 10, 15 cm depletion of water level below the soil surface and continuous flooding) as subplot treatments in split plot design on clay loam soil. Significantly least weed abundance was observed in normal transplanted rice and with mechanized SRI with continuous flooding irrigated conditions during rabi seasons of 2021 and 2022. Wet direct seeded rice exhibited severe weed infestation (significantly high weed density and weed drymatter) under alternate wetting and drying conditions compared to mechanized SRI and normal transplanting method.

“…Grain yield was maximized in this cultivar when grown in environments where sowing is performed from May 1 to June 1. The timing of sowing of the flax cultivars significantly affects growth and development (Ganvit et al 2019), as well as grain yield (Dabalo et al 2020), and grain oil content (Stanck et al 2017).…”

“…This shows that plant height was more subjective by genomic than weed management. Bekele et al (2018) and Ganvit et al (2019) examined the enlarged plant height by means of the control plot as a consequence of severe opposition between plants which caused them to get longer in the exploration of light and the absence of accessibility of abundant growth-boosting aspects in the control plot that permitted the plants to progress in height, the struggle among weeds and crop for sunlight and space in control plots caused in elevated plants. The maize plant height was moderately higher in plots that were treated with herbicides for weed control than in the control plots where no herbicide was sprayed (Nawab et al 1999;Hassan et al 2010;Hunde et al 2021;Memon et al 2022).…”

A large quantity of maize is wasted due to weeds in Holeta and Ejere districts of Central Ethiopia. The weeds invade the crop fields during the early growth stage by germinating from the soil and driving nutrients from the soil. To manage the crop from the weeds, farmers exercise cultural weed control methods. However, this method of managing the weeds from the crop is tiresome and inefficient. Hence, it was assumed that application of the crops with herbicides soon after sowing or practicing weed free from emergence up to the time of maturity prevents the weeds. The study was to test the efficacy of herbicides on several weed species and increase maize production. The RCBD with three replications was used with plot dimensions every one calculating 5m x 4m. Plots were treated with AGENT 600 ml ha -1 , COYOTE 440 SE 3L.ha -1 , Primagramgold 3L.ha -1 , S-Maspor 960 EC 3L.ha -1 , Surestart 3L.ha -1 and weedy check. The application of S-Maspor 960 EC reduced the density of Corrigiola capensis by 93.3 %, Plantago lanceoleta by 51.6%, Spergula arvensis by 51.6% in Ejere tested location whereas treating plots with Surestart significantly decreased the remaining weed species in Holeta and Ejere. Furthermore, significantly increased cob length by 4.3%, grain yield by 17.58 folds, and reduced yield loss by 93.3% as compared to weedy check plots were also received from the application of Surestart. It is concluded that the application of Surestart 3L ha -1 has proven to significantly decrease weed density and enhanced grain yield.
