Description :
Field experiment was conducted during the rabi seasons of 2015 - 16 at shankarnagar farm of Agril. Botany Section, College of Agriculture, Nagpur to study the effect of foliar application of different concentrations of putrescine (25, 50, 75, 100, 125 and 150 ppm) and naphthalene acetic acid (25 and 50 ppm) either individually or in combination at one physiological stages (vegetative, 30 - 35 DAS) on chemical, biochemical, yield and yield contributing parameters of chickpea ( Cicer arietinum L.). The field experiment was laid out in Randomized Block Design with three replication. The observations were recorded at 25, 45, 65 and 85 DAS. The obtained results showed that 50 ppm NAA plus 100 ppm putrescine significantly improved nitrogen, phosphorus, potassium, chlorophyll content in leaves and protein content i n seeds of chickpea. Yield contributing parameters viz., number of pods plant - 1 , weight of 100 seeds and seed yield ha - 1 were also significantly enhanced. Application of putrescine and/or NAA at 100 and 50 ppm respectively produced the highest number of pods which resulted in substantially the highest seed yield. Putrescine and NAA increase the seed yield by 25.3% and 26.0% ha - 1 respectively, while the combination of 50 ppm NAA plus 100 ppm putrescine increased it by 33.2%. But, considering the B : C ratio foliar application of 50 ppm NAA was found most effective treatment having B : C ratio of 5.9 as compared to 5.1 in cont rol.
