Response of Faba Bean (Viciafaba L.) To Different Planting Densities and Bio-Mineral Fertilization Systems.

摘要

Two field experiments were conducted during two winter seasons (2010/2011 and 2011/2012) in the Experimental farm of Faculty of Agriculture, Cairo University, Giza, Egypt to study the response of faba bean to two planting densities (25 or 33 plants/m2) and different fertilization systems (100% mineral NP normal levels i.e, 70% (NP)+ seed inoculation with Rhyzobium leguminosarum, 70% (NP)+ compost as an organic fertilizer and 70%(NP)+ seed inoculation + compost on growth and productivity of Giza 40 cultivar. Planting density, fertilization treatments and their interactions had a significant effect in all characters under study. Use of 25 plants/m2 (105,000 plants/faddan) increased number of branches / plant, number of pods /plant, 100-seed weight, seed weight/plant, straw,seed yield/ faddan, nitrogen and protein percentage. Use of 70% NP + Rhizobium + compost resulted in significant increased in number of branches and pods / plant and hence seed yield/plant, per faddan, nitrogen and protein percentage. Planting 25 plants Im1 with 70% NP+ Rhizobium + compost gave the highest number of branches / plant, number of pods/ plant, 100- seed weight and hence the straw and seed yields / fed. as well as recorded the highest average of nitrogen and protein percentage.
