Effect of intercropping systems on growth, yield components, guaran production and chemical constituents of guar plant [electronic resource].

Includes references.

The present work aimed to study the effect of intercropping systems on growth, seed yield components, guaran production and chemical constituents of guar plant when intercropped with roselle plant. The intercropping systems used were (1+1), (1+2), (1+3), (2+1) and (3+1) of roselle andguar, respectively. Furthermore, solid system of guar was used as control. The obtained results refered to that using most of intercropping systems, except that of (1+1), increased plant height, number of branches or leaves, fresh and dry weights of leaves, shoots or root and root length per plant compared to solid planting system of guar. Using of intercropping system of one row of roselle with one row of guar (1+1) gave the highest values of pods number and weight of seeds per plant comparing to solid planting system and the other intercropping systems. In addition, the intercropping system of one row of roselle with three rows of guar (1+3) gave the highest values of seed yield per faddan as well as total carbohydrates phosphorus and potassium percentages and contents in guar seeds compared to the solid planting system. In the same time, total nitrogen and protein contents per plant seeds were increased by using of intercropping system of (1 + 1) compared to solid planting system or the other systems. Generally, it could be concluded that using of intercropping system of alternating one row of roselle with three rows of guar resulted in the highest values in seed yield per faddan, guaran production as well as some chemical constituents of guar plant cultivated under Sharkia Governorate conditions.
