Abstract

The present investigation was carried out for “Impact of chitosan based bio-active seed coating on field performance, yield and yield attributing characters of Chickpea (Cicer arietinum L.)”. For this purpose, 11+1 treatments including control on Chickpea seeds variety-Pragati were used to study under field conditions during Rabi, 2022. Field experiment was laid out in Randomized Block Design with three replications. Analysis for the data based on ANOVA and mean performance in field experiment revealed significance mean sum of squares due to seed treatments for all the characters under study. In order to response different method of seed treatment were evaluated by screening a range of duration and concentration viz T0- Control, T1- Chitosan @1%+Salicylic acid @1% for 8Hrs, T2- Chitosan @2%+Salicylic acid @1% for 8 hrs, T3- Chitosan @3%+Salicylic acid @1% for 8Hrs, T4- Chitosan @4%+Salicylic acid @1% for 8hrs, T5- Chitosan @5%+Salicylic acid @1% for 8hrs, T6- Chitosan @1%+Bee Wax @0.1% for 8hrs, T7- Chitosan @2%+Bee Wax @0.1% for 8hrs, T8- Chitosan @1%+Bee Wax @0.1%+Lime essential Oil @0.1% for 8hrs, T9- Chitosan @1%+Oleic acid @1% for 8hrs, T10- Chitosan @2%+Oleic acid @1% for 8 hrs, T11- Chitosan @2%+Oleic acid @1%+Lime essential Oil @0.1% for 8hrs. To find out Impact of different concentration seed treatment on Chitosan, Salicylic acid, Bees Wax, Oleic acid, Lime essential oil on growth, yield and yield attributing traits of Chickpea showed that significant treatment Field emergence, Plant height, Number of Branches, Days to 50% flowering, Days to maturity, Number of leaves per plant, Number of pods per plant, Number of Seeds per pod, Seed yield per plant, Seed yield per plot, Biological yield, Harvest index. The study helps to improve the quality of seed with help of Chitosan, Salicylic acid, Bee Wax, Lime essential Oil, Oleic acid seed bioactive coating treatment which are cost effective and economic, non-toxic, eco-friendly sources. seed bioactive coating treatment with it is concluded from the present study that Impact of chitosan based bioactive seed coating on germination growth and yield of Chickpea. T4- Chitosan @4%+Salicylic acid @1% for 8 hrs showed significantly enhance the yield and yield attributing traits followed by T6- Chitosan @1%+Bee Wax @0.1% as compared to control(untreated) seeds. These recommendations are based on six months experimentation and the treatment recommended is T4- Chitosan @4%+ Salicylic acid @1% for 8 hrs.
