Abstract
A series of laboratory, field and storage experiments were conducted to study the effect of seed priming on emergence, yield and storability of soybean (Glycine max) cv. William-82 NWFP Agricultural University, Pershawar during 2003 and 2004. Three seed priming durations (6, 12 and 18 h) and five PEG 8000 concentrations (0, 100, 200, 300 and 400 g L-1 water) along with dry seed (non primed as control treatment were included in the experiment. Seeds were primed, air dried and sown in the field on 3rd May, 2003 and 5th May 2004. Analysis of two years average data indicated that plants of primed seed plots took fewer days to emergence, flowering and maturity as compared with plants of non primed seed plots. Primed seed plots produced more plants m-2, taller plants and higher grain yield as compared with non primed seed plots, Days to emergence and maturity increased with increase in seed priming duration. Emergence m-2 , branches plant-1 and grain yield decreased with extending seed priming duration. Days to emergence, flowering and maturity decreased with increase in PEG concentration from 0 to 300 g L-1 water. Emergence m-2, number of branches plant-1, grains pod-1 and grain yield enhanced with increase in PEG concentration from 0 to 300 g L-1 water. In the storage experiments, primed seed produced higher germination, greater seedling storage experiments; primed seed produced higher germination, greater seedling dry weight and less electrical conductivity for seed stored at room temperature. PEG concentration of 300 g L-1 water resulted in higher germination and seedling dry weight. However water primed seed recorded maximum leachate conductance. Germination and seedling dry weight decreased with increase in seed priming duration. Seed stored in plastic bag resulted in maximum germination while seed stored in gunny bag produced greater seedling dry weight. Seed stored in galvanized iron sheet boxes and earthen posts recorded maximum leachate conductance. Germination and seedling dry weight deceased while electrical conductivity enhanced with increase in storage time. For the seed stored at controlled temperature (4OC), primed seed resulted in higher germination, seedling dry weight and less electrical conductivity. Higher germination and seedling dry weight was recorded for seed treated with 300 g L-1 water. Germination and seedling dry weight decreased while electrical conductivity with increase in storage time.
