to study the including rhizobium treatment (strain numbers of 133, 116 & combination of them) along with 100% nitrogen fertilizer application and a check (no inoculation & no fertilizer) on certain agronomical and physiological traits of three common bean cultivars (viz. bahman, darkhshan & sayiad) a field experiment was performed at research station of university of tehran (karaj-iran) in 2010...

Selection of plant species, their varieties or hybrids and the formation productivity is an urgent need today due to shortage biofuel production at world level. The purpose research was reveal influence technological measures (row spacing density standing) on elements crop structure castor varieties. Research conducted during 2020-2021in field conditions study stand row width Khortytska 3 Olesi...

The use of glyphosate resistant soybean (GRS) cultivars has increased rapidly from their introduction in 1996 to over 50% of Wisconsin soybean acres in 1999. While much research has been conducted using conventional cultivars to measure the influence of row spacing and seeding rates on soybean growth and yield, little has been done with new GRS cultivars. It may be necessary and/or more profita...

The present field experiment was conducted during winter (rabi) seasons of 2018–19 and 2019–20 at ICAR-Central Potato Research Institute, Regional Station Jalandhar, Punjab to find out the suitable planting geometry dehaulming date for enhancing seed potato (Solanum tuberosum L.) yield profitability under north-western plains India. According study strongly influenced size tuber quality. Among ...

Objective: In order to study the effect of solopotasse fertilizer on yield and essential oil of cumin medicinal plant. Methods: A experiment in randomized complete block design with three replications conducted in kermam city, Iran, in 2013. solopotasse fertilizer in four levels (0, 50, 100 and 150 kg/h) investigated. Plant height, number of umbrella per plant, number of seed per umbrella, 1000...

in this paper, a numerical method for nding minimal solution of a mn fullyfuzzy linear system of the form ax = b based on pseudo inverse calculation,is given when the central matrix of coecients is row full rank or column fullrank, and where a~ is a non-negative fuzzy mn matrix, the unknown vectorx is a vector consisting of n non-negative fuzzy numbers and the constant b isa vector consisti...

This study was aimed to the examination of the effect of tillage row spacing and bush spacing on the performance and components of Phaseou vulgaris var. (line: cos16). The investigation was conducted as cut terraces and in terms of complete random blocks in three replicates at Brujerd Agricultural Research and Natural Resources in the agricultural year 2009-2010. Here, the main terraces with th...

Pre-dispersal seed predators are often chosen as biocontrol agents because of their high impacts on plant fitness; however, they have a mixed record in realizing decreased plant population growth. Few studies have experimentally removed agents to explore their impact on weed population growth. Here, we used manipulative experiments with invasive yellow starthistle (YST), Centaurea solstitialis,...

tall fescue (lolium arundinaceum (schreb) sj darbysh.) is one of the fescue species that widely used as forage grass. tall fescue is self-incompatible and wind cross pollination. this study was conducted to study agronomic and morphological characteristics of 25 polycross families of tall fescue during 2011 and 2012 at research station farm in isfahan. number of days to pollination, height of p...

Manual transplanting, a pre-dominant practice in almost all the paddy growing areas India, is laborious, burdensome, and has many expenses on raising, settling, transplanting nursery. The process’s limitations motivated replacement of conventional methods. study was divided into two phases. first phase included laboratory testing three levels metering mechanisms, namely cell type (M1) with 10 c...
