to study the effect of plant density on seed yield and yield components of two lentil cultivars a field experiment using factorial design based on a complete block design was conducted with three replications at research farm of college of agriculture and natural resources, university of tehran (karaj) in 2008. treatments were lentil varieties (ziba, mardom), and plant densities (80, 160, 240, ...

in order to study of some effective phenologic and physiologic characteristics on 18 sunflower hybrids yield under optimum conditions, an experiment was conducted as randomized complete block design with three replications at the research field of seed and plant improvement institute-karaj in 2006-2007. the result indicated that the hybrids showed significant difference in phonologic characteri...

African yam bean (Sphenostylis stenocarpa) is an underexploited legume with the potential of becoming an alternative food staple to alleviate the problem of food security. An assessment was carried out on the growth and yield of AYB affected by Telfairia mosaic virus (TeMV) Infection. Telfairia mosaic virus caused severe mosaic, leaf distortion and malformation on AYB. Analyses of results revea...

water deficit stress is the most important environmental constraint for growth, yield and productivity of crops, including the oil seed crops. this study was aimed at studying the influence of differing irrigation régimes on growth, chlorophyll , proline and some antioxidants content along with grain yield, yield components and oil content of sesame genotypes using a 4-replicate split plot rand...

Identifying key yield components can help establish better crop management strategies to increase crop yield. The present research was conducted in south-western Saskatchewan in 1999 and 2000 to determine the interrelationships among various yield components and their direct and indirect effects of each component on seed yield of field pea (Pisum sativum L.). The semi-leafless cultivar Carrera ...

katoul is a new soybeam cultivar originated from a genotype named d.p.x.3589 imported from the united states of american in 1990. this genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in gorgan and other research stations during 1999-2002. the mean seed yield of d.p.x.3589 in all these experiments was 3333 kgha-1 ...

milkthistle (silybum marianum l.) is a rangeland medicinal plant growing wild in different locations in iran. in the present research work, the effect of n, p and k in their different proportions of n0p0k0, n100p100k50, n150p150k100 and n200p200k150 kgha-1 as compared with control (no fertilizer application) on the plant's growth was put to test. suc variables as plant height, no. of capit...

A field experiment was conducted on the Effect of phosphorus fertilizer and seed rates growth yield common bean (Phaseolus vulgaris L) at Farm agriculture faculty Kunduz University during spring season 2023 to determine optimum for maximum in northeast Afghanistan (Kunduz province). The treatment consists three levels (0kgP2O5ha-1, 40kgP2O5ha-1 80kgP2O5ha-1) four combined (125 kgha-1, 150 175 k...
