The Effect of Organic and Inorganic fertilizers on growth and Yield of Sunflower (Helianthus annuus L.)

Abstract

A field experiment was carried out at Sudan university of science and technology college of Agriculture studies Shambat, winter season ( 2017 2016 ) to study the effect of organic and inorganic fertilizers on growth and yield of some sunflower (Helianthus annuus L. ) genotypes. The experiment was designed at factorial experiment in randomized complete block design with three replications and used three genotypes (V1= 0398, V2=SIRANA, V3=MR1362) and two types of fertilizers: Organic (compost), Inorganic fertilizers (Urea and Diamoniumphosphate). The parameters ware taken from the experiment is (plant height (cm), number of leaves, stem diameter (cm), leaf area (cm2), disk diameter (cm), 100-seed weight (g) and yield (ton/ha). The results showed that significant different among the fertilizers in: (plant height, number of leaves, stem diameter, leaf area, 100-seed weight and yield (ton/ha) butno significant different in disk diameter (cm). also that significant different among genotypes in number of leaves and yield but no significant different at all the rest of parameters and no significant different at interactions in all parameters except the yield (ton/ha).
