Effect of plant density, potassium fertilization and foliar application with some micro-element nutrients on the yield and quality of sweet sorghum [electronic resource].

Includes references.

Two field experiments were conducted at the Sabahia Research Farm in Alexandria Governorate, Egypt during 2009 and 2010 summer seasons to study the effect of plant density (25, 30 and 35cm), potassium fertilization (0 and 50kg Ifad land some micro-elements, as foliar application with chitocare after 45 days and 90 days from planting, on yield and quality of sweet sorghum (Sorghum bicolor, L.) The treatments were arranged in split-split plot design in three replications. The most important results were summarized as follows. Plant density at 35 em led to attain the highest values of leaf area index, stalk yield (kg), weight of syrup and T.SS %. Potassium fertilizer level (50kg k₂O fad) gave the highest leaf area index. Foliar spraying with chitocare showed supevority of leaf area index, stalk yield, weight of syrup and T.S.S % and juice quality parameters. As for, the interaction between the potassium fertilizer level and foliar spraying chitocare had significant effect for T.S.S %.
