Efficacy of herbicides on yield and economics of summer groundnut as well as residual effect on succeeding crops

Abstract

The present investigation was conducted to evaluate the efficacy of herbicides on yield and economics of summer groundnut as well as residual effect on succeeding crops during two consecutive summer season of 2018 and 2019 at College of Agriculture, Anand Agricultural University, Jabugam, Gujarat Oxyfluorfen, quizalofop-ethyl, imazethapyr, imazethapyr + imazamox (premix) and fluazifop-p-butyl + fomesafen (premix) were tested as alone, with integration as well as sequential application in comparison with IC fb HW at 20 and 40 DAS and weedy check in randomized block design with three replications. All the weed management practices significantly reduced the density and dry biomass of weeds and increased the pod yield of groundnut. Results revealed that Oxyfluorfen 180 g/ha PE fb IC + HW at 40 DAS provide effective control of weeds at all the intervals with higher pod and haulm yields as well as net return and BC ratio of groundnut followed by Oxyfluorfen 180 g/ha PE fb Imazethapyr 100 g/ha PoE, IC fb HW at 20 and 40 DAS, oxyfluorfen 180 g/ha PE fb Imazethapyr + Imazamox 70 g/ha PoE (premix) and fluazifop-p-butyl + fomesafen 250 g/ha EPoE (premix) fb IC + HW at 40 DAS. The plant stand, plant height and dry matter production of cotton, maize and green gram were not affected by the application of any herbicides in applied in preceding summer groundnut.

Impact of fermented organic formulations combined with inorganic fertilizers on broccoli (Brassica oleracea L. var. italica Plenck) cv. Palam Samridhi

“…Both Jeevamrut and Beejamrit exhibited high levels of microbial activity and growth hormones, which may have boosted soil biomass and promoted the availability and absorption of both added and naturally occurring nutrients, resulting in the highest crop growth and production [ 31 ]. The increase in nitrogen uptake was noticed with the application of jeevamrit which contains cow urine which is rich in uric acid, a rich source of nitrogen [ 32 ]. Foliar spray application of jeevamrit increases the supply of nutrients content and makes the nutrients readily available to the plants.…”

“…Bionutrients constitute smaller quantities of plant growth regulators (IAA and GA), which create stimuli in plant systems, which in turn enhance growth and development, leading to better fruit yield and quality (Chandrakala et al, 2011 andVij et al, 2022). Cow urine rich in uric acid, a source of nitrogen, is a readily soluble and liquid form, one of the important compounds in bionutrients that is readily available to plants and directly influences the nitrogen content (Patel et al, 2018). Mulching includes live mulch, soil mulch and straw mulch, which helps to alter the environment surrounding the plant rhizosphere.…”
