Storage of Rabi or Summer Groundnut with Desiccants to Prolong Seed Viability and Seedling Vigour

Basave Gowda, Y.A. Nanja Reddy

Abstract


Experiment was conducted to study the storability of rabi or summer grown groundnut pods with desiccants to prolong seed viability and seedling vigour. Pods of variety KRG-1 produced during rabi or summer season were stored in different packaging materials with and without desiccants. Germination percentage, seedling dry weight, seedling vigour, electrical conductivity and field emergence percent were recorded at 2, 5 and 8 months after storage (MAS). At 8 MAS, highest germination (72 %) was maintained in pods stored in Poly lined (300 gauge) gunny bag (PLGB) + silica gel (30g.kg-1 pod) which was on par with PLGB + Calcium chloride (10g.kg-1 pod), whereas only 63 % germination was recorded in pods stored in gunny bag. Seedling vigour and field emergence were also highest in PLGB with desiccant. If the rabi or summer produce is used for seed purpose, farmers may be advocated to dry the produce to 7 % seed moisture content and store in the gunny bags lined with polythene bag (300 gauge) with desiccant, either silica gel (30g.kg-1 pod) or Calcium chloride (10g.kg-1 pod) to achieve proper crop stand and productivity.
