dc.description.abstract | The experiment entitled “Effect of different seed priming treatments on seed yield and its quality in groundnut (Arachis hypogaea L.)” was carried out in Sagdividi Farm, Department of Seed Science and Technology during kharif-2018 and laboratory experiment at Seed Testing Laboratory, Department of Seed Science and Technology, Junagadh Agricultural University, Junagadh. The field experiment was conducted in FRBD with three replications. There were two genotypes viz., GG-20 and GJG-22 and nine priming treatments viz., untreated seed (control), water, KH2PO4 (1%), CaCl2 (1%), KCl (1%), Boron (0.5%), GA3 (25 ppm), MnSO4 (0.5%) and KNO3 (1%) for 6 hours priming followed by shade drying. The observations on different plant characteristics such as field emergence percentage, days to 50 per cent flowering, plant height, days to maturity, number of mature pods per plant, seed yield per plant, seed yield per plot, seed yield per hectare, harvest index and laboratory observations such as 100 seed weight, germination percentage, root length, shoot length, seedling dry weight, seedling vigour index-I, seedling vigour index-II and electrical conductivity were recorded. All the field observations were recorded under the sun light in three replications. Plant height, number of mature pods per plant and seed yield per plant were observed from five tagged plants. GJG-22 genotype took lower days to 50 per cent flowering and days to maturity as compared to GG-20 genotype. Plots having seed primed with CaCl2 (1%) recorded earlier flowering and days to maturity which was at par with seed primed with KCl (1%) and KH2PO4 (1%). GJG-22 genotype showed significantly the highest field emergence percentage, plant height, number of mature pods per plant, seed yield per plant, seed yield per plot, seed yield per hectare and harvest index over genotype GG-20. Plots having seed primed with CaCl2 (1%) significantly showed highest field emergence percentage, plant height, number of mature pods per plant, seed yield per plant, seed yield per plot, seed yield per hectare and harvest index which was at par with seed primed with KCl (1%) and KH2PO4 (1%). The genotype GJG-22 primed with CaCl2 (1%) was non-significantly highest in field emergence percentage, plant height, number of mature pods per plant, seed yield per plant, seed yield per plot, seed yield per hectare and harvest index; while non-significantly lowest in days to 50 per cent flowering and days to maturity.Abstract In seed quality characters seeds of genotype GJG-22 was better in 100 seed weight, germination percentage, root length, shoot length, seedling dry weight, seedling vigour index-I, seedling vigour index-II and electrical conductivity than seeds of genotype GG-20. Seed primed with CaCl2 (1%) was better in 100 seed weight, germination percentage, root length, shoot length, seedling dry weight, seedling vigour index-I, seedling vigour index-II and electrical conductivity. The higher seed quality characters noticed in CaCl2 primed seeds might due to the role of calcium in membrane stabilization and act as an enzyme cofactor. Seeds of genotype GJG-22 primed with CaCl2 (1%) was better in root length, shoot length, seedling dry weight, seedling vigour index-I, seedling vigour index-II and electrical conductivity. While its non-significant effect on 100 seed weight and germination percentage. It was observed that seed priming has a positive effect on the sowing quality of groundnut seeds, as well as performance, leading to higher yield. Seed priming with CaCl2 (1%) followed by KCl (1%) and KH2PO4 (1%) for 6 hours followed by shade drying recorded higher values for growth and seed yield characters, while seed priming with CaCl2 (1%) which recorded higher value for quality characters as compared to other priming treatments. The increase in the seed yield by CaCl2 (1%) followed by KCl (1%) and KH2PO4 (1%) were mainly due to increase in field emergence percentage and number of pods per plant. The increases in growth, seed yield and quality characters due to the activities of numerous enzymes, enhanced metabolic activity, presence of growth promoters, make available high energy biomolecules, improved mobilization of nutrient and more food reserve materials in seeds. It is concluded that the seeds of groundnut primed with the CaCl2 (1%) for better field emergence percentage, successful establishment of seedlings and also to get better pod yield and quality of groundnut crop. | en_US |
