Effect of micronutrients (Zn, B and Mo) foliar application at various growth stages of chickpea (Cicer arietinum L.) on yield and yield components [electronic resource]

Two field trials were conducted during 2015/16 and 2016/17 winter seasons, at Agric. Res. Stat., Fac. Agric., Cairo Univ., Giza, Egypt, to study response yield and its attributes of chickpea to zinc (Zn), Boron (B) and molybdenum (Mo) in four combination at three growth stages; V3: vegetative stage (30 days after planting), R1: start of flowering (45 days after planting) and R6: pod initiation (60 days after planting). The treatments of micronutrients foliar application were T1 (application with tap water), T2 (Zn 0.5 g/l + B 0.5 g/l), T3 (Zn 0.5 g/l + Mo 0.5 g/l), T4 (B 0.5 g/l + Mo 0.5 g/l), T5( Zn 0.5 g/l + B 0.5 g/l + Mo 0.5 g/l). The T5 treatment (Zn + B + Mo) produced significantly the greatest seed yield feddan-1 (702 and 727 kg), stover yield feddan-1 (2275 and 2276 kg), harvest index (23.6 and 24.1%) respectively, in both seasons. The results indicated that the spraying time of microelements did not significantly effect on yield traits in 2015/16 and 2016/17 seasons. The greatest productivity of seed (705 and 732 kg/ fed.) in 2015/16 and 2016/17 seasons, respectively was recorded by combined application of zinc (0.5 g/l) + Boron (0.5 g/l) + molybdenum (0.5 g/l) as foliar spray at start of flowering stage compared with other tested treatments. Combined application of zinc, boron and molybdenum as foliar spray at 45 DAP significantly enhanced the crop yields and protein (%) in seed of chickpea.
