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...

in order to study the effects of different irrigation system and different amounts of nitrogen fertilizer on yield and quality of sugar beet, an experiment was conducted at ekbatan research station, hamedan during 2005-2006 as split plot based on randomized complete block design  with three replications. the main plots were irrigation systems (furrow, sprinkler and drip irrigation) and subplots...

to study the effects of different amounts of sulphur and boron fertilizers on grain yield and grain quality of bread wheat cultivar pishtaz, an experiment was conduncted in karaj during two cropping seasons 2001-2003. three levels of sulphur (s0= 0, s1=250 and s2= 500 kgha-1) and three levels of boron (b0= 0, b1= 20 and b2= 40 kgha-1) were different treatments of the experiment arranged in rcbd...

Crop management like planting time is a crucial factor for maximizing yield especially seed production. Seed production of carrot greatly influenced by temperature as it requires adequate periods cool (vernalization) flowering and To find out optimum steckling quality the experiment was conducted at Field Laboratory Horticulture Farm, Bangladesh Agricultural University, Mymensingh during period...

this study was conducted to determine the effect of variable nitrogen supply on yield parameters of two sugar beet varieties, as well as on biomass allocation to different parts of sugar beet plant at safi-abad agric. res. center during 2003-4 and 2004-5. five nitrogen rates (0, 60, 120, 180 and 240 kgha-1) and two monogerm sugar beet varieties (shirin and rasol) arranged as factorial in a rand...

Onion is an herbaceous biennial monocot cultivated as annual. In most research the greater seed yield in onion cultivars used to be due higher range of stalks per plant and a wider umbel diameter which had been influenced through utility Nitrogen Phosphorus fertilizers. The wide variety flower opening on every day was by using hours sunshine attention phosphorous nitrogen. remedies tended decre...

in order to determine the effect of different tillage methods on grain yield and yield components of two wheat cultivars an experiment was conducted in sanandaj in during 2005 and 2006-2007. experiment was carried out in a split plot design based on rcbd with four replications. the three methods of tillage, including moldboard plow, chisel plow and no tillage were arranged as main plots, and tw...

In the context of climate change, sowing date and cultivar choice can influence productivity sorghum, especially where production is constrained by low soil fertility early terminal drought across challenging agro-ecologies north-eastern Nigeria. Planting within an optimal window to fit cultivar’s maturity length critical for maximizing/increasing crop yield following appropriate climate-smart ...
