Effect of Vinclozolin Spray, Plant Growth Habit and Inter-Row Spacings on Botrytis Grey Mold and Yield of Chickpea uri icon

abstract

  • The chickpea genotypes ICCL 87322 (with tall, erect and compact growth) and H 208 (a traditional bushy, spreading type) were planted at row spacings of 30 X 10 or 60 X 5 cm, artificially inoculated with B. cinerea and sprayed or not sprayed with vinclozolin. Fungicide application reduced grey mould severity and increased yields in both seasons. The wider row spacing resulted in lower disease ratings and higher yields; ICCL 87322 yielded over 5 t/ha in the 60 \mult\ 5 cm rows in the 1988/89 season and consistently gave lower diseases ratings and higher yields than H 208., 3 ref., The chickpea genotypes ICCL 87322 (with tall, erect and compact growth) and H 208 (a traditional bushy, spreading type) were planted at row spacings of 30 X 10 or 60 X 5 cm, artificially inoculated with B. cinerea and sprayed or not sprayed with vinclozolin.
