The size and activity of the soil microbial biomass was studied in the plant row and in the inter-row of a sugarcane field under burning or green cane harvesting. The sites sampled were on the long-term trash management trial situated at Mount Edgecombe. Soils were sampled to 30 cm depth in (i) the centre of the plant row, (ii) 30 cm out from the row centre and (iii) 60 cm out from the row cent...

A field study was conducted on sandy clay loam soil to evaluate the impact of row spacing and N application method on the productivity of maize (Zea mays L.). The experiment was conducted using four row spacings (60 cm spaced single rows, 90 cm spaced double row strips, 90 cm spaced single rows and 135 cm spaced double row strips) and two methods of nitrogen (N) application (broadcast and band ...

background and objectives: potato (solanum tuberosum l.) plant is one of leading agricultural products in the world. it is the fourth most cultivated food crop after wheat, rice and maize. planting density and weight of minituber are the factors influencing on the yield and yield components on seed tuber production in potato. plant density strongly affected yield, both by number and by weight a...

Abstract Field experiments were conducted over 2 yr (2019 to 2020) at two locations in Iowa evaluate multi-tactic strategies for managing multiple herbicide–resistant (MHR) waterhemp [ Amaranthus tuberculatus (Moq.) Sauer] a corn ( Zea mays L.)–soybean Glycine max (L.) Merr.] rotation. The effect of three herbicide programs on A. control was tested (2019). effects the prior year’s weed control,...

Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30,...

abstract in order to investigate the effect of crop row spacing and cocklebur (xanthium strumarium) densities on yield and its components of two sesame cultivars, a field experiment was conducted in 2009-2010 growing season at research farm of university of agricultural sciences and natural resources of gorgan, iran. the experiment was established as factorial arrangement using a randomized com...

according to the contradictory reports of researchers, tillers may have positive or negative effect on wheat yield. thus, this study was conducted to investigate the role of tillers on wheat yield under two row spacing of 12.5 and 25 cm and four plant densities of 125, 250, 375 and 500 plants per m2, at gorgan university of agricultural sciences and natural resources farm in anbare-ololum reign...

in order to study the sowing system, row distance and weeding effect on yield and yield components of intercropped maize with peanut, this experiment was conducted, as factorial based on a rcbd with three replications at the research farm of agriculture center of zabol university (iran) during growing season 2011- 2012. sowing system were four levels including sole maize, sole peanut, 50% maize...
