in order to investigate effect of organic manure and super absorbent on physiological and biochemical traits of potato (solanum tubersum, cv marfona), a split plot experiment was conducted as randomized complete block design with three replications at research farm, agriculture college, university of razi in 2010. main factor included two levels of super absorbent a200 (0 and 70 kg/ha,) and spl...

The experiment was carried out to evaluate the effect of different levels of dried slurry (DS) as source of nitrogen fertilizer on yield and chemical composition of maize fodder (Zea mays). Four levels of DS (0, 10, 12 and 14 ton/ha) were applied in a Randomized Block Design (RBD). Green biomass yields was significantly higher in DS incorporated groups compared to control. The highest (P<0.01) ...

in recent years, surplus usage of chemical fertilizers and inattention the importance organic matter to improve soil fertility, leading to increasing use of chemical fertilizer, environmental pollution and etc. in order to study the different fertilizer levels (organic, chemical and combined) on yield of grain corn (s.c.704) experiment was conducted at the research farm faculty of agriculture t...

in order to investigate the effect of fertilizer types and irrigation regimes on quality criteria of three medicinal plants: lavander, rosemary and hyssop, an experiment was conducted at research field of faculty of agriculture, ferdowsi university of mashhad, during two growing years of 2007-2009. a split plot design with three replications was used. treatments were three irrigation intervals ...

Biomass and energy evaluation was carried out in the Municipality of Teresópolis Rio de Janeiro, Brazil. Th e following agricultural and natural systems were considered: (i) vegetables systems (leaf, fruit and mixed vegetables); (ii) citrus; (iii) ecological agro-forestry; (iv) cattle ranching, (v) silvopastoril systems, (vi) forest fragments and, (vii) forest in regeneration stage (1, 2 and 3 ...

Two soil compaction trials were conducted at Riverside and Kaalrug near Malelane in the northern irrigated area of the South African sugar industry. Treatments for the trial at Riverside were fresh citrus peel incorporated at 318 tons/ha (95 ton/ha dry material), dry cane trash at 30 tons/ha left on the soil surface and a combination of these two. Compaction was applied by driving a 30 ton rigi...

in order to study the influence of municipal solid waste compost and nitrogen fertilizer on grain and forage yield of sweet corn an experiment was conducted at marvdasht during 2009. the experiment was arranged in split plots based on randomized complete block design with two factors and three replications. main plot included 5 levels of nitrogen fertilizer (100, 150, 200, 250, 300 kg n ha-1) a...
