Influence of land configuration, irrigation levels and nipping on growth and yield of chickpea (Cicer arietinum L.)

Abstract

An experiment was conducted at soil and water management research farm, NAU, Navsari during rabi seasons of 2017-18. Plant height, branches per plant, dry matter accumulation, pods per plant, 100 seed weight, grain and stover yield as well as harvest index and economics significantly influenced by different treatments of land configuration, irrigation levels and nipping. The field experiment consist of three land configuration (L1: Flat bed, L2: Ridge and furrow and L3: Raised bed), four irrigation levels (I1: 20 DAS, I2: 20 & 40 DAS, I3: 20, 40 & 60 DAS and I4: 20, 40, 60 & 80 DAS) and two nipping treatments (N0: Non-nipping and N1: Nipping at 25 DAS). Raised method of land configuration recorded significantly higher growth, yield and economics than flat bed. Among irrigation levels, irrigation applied at 20, 40, 60 and 80 DAS showed higher growth and yield parameters as well as economics. In case of nipping at 25 DAS recorded higher branches per plant, pods per plant yield and economics, whereas, non-nipping was observed more plant height. However, 100 seed weight and harvest index was not affected significantly by different treatments of land configuration irrigation and nipping.
