The continuous rise in global population demands more food production under limited land resources accompanied by climate change. More oversupply of quality seeds to meet ever-growing food demand is a highly challenging task. Seeds with low vigour level limit the growth and yield of crops at varied field conditions. Hence, an experiment was conducted to develop a technique for the fast and homogeneous growth of kabuli chickpea seeds. The priming treatments evaluated in the present study enhanced the various seed quality parameters of kabuli chickpea significantly when compared to control. Hydro-priming for 4 hours (at 20°C) and air drying for 72 hours showed better results compared to rest of the treatments both in fresh seeds which recorded higher first count (66.38%), germination (92.50%) root length (11.85 cm), shoot length (6.16), mean seedling length (18.01), dry seedling weight (747 mg), seedling vigour index-I (1665), higher speed of emergence (0.3992) and old seeds with higher first count (61.88%), germination (74.13%) root length (8.15 cm), shoot length (5.85 cm), mean seedling length (14.00 cm), seedling dry weight (611 mg), seedling vigour index-I (1056), higher speed of emergence (0.3814). The aged seeds have recorded 29 % increase in germination percentage in contrast to 8 percent increases in fresh seeds. Kabuli chickpea seeds could be subjected to hydropriming, an affordable, alternative, and eco-friendly technique for improving seed and seedling vigour of kabuli chickpea.

The Impact

Background: Aspergillus niger and A. flavus cause rotting, damping-off, loss in germination and toxification of oil seeds. Aspergillus is a common mold in tropical and Sub-tropical countries and causes aflatoxin contamination. A. flavus and A. niger were responsible for storage rot of groundnut. In addition to storage rot, aflatoxin contamination also leads to adverse effects on consumer health. Therefore, present study was conducted to estimate the impact of both A. niger and A. flavus on seed quality parameters of groundnut. Methods: Effect of major seed borne fungi A.niger and A. flavus on seed quality characters of thirteen different genotypes of groundnut was observed in the present study. All the seedling quality characters were measured as per ISTA guidelines. Result: On an average A. niger caused 25.14, 25.18, 43.99, 26.20 and 44.75 per cent reduction in seed germination, seedling length, seedling vigour index I, seedling dry weight and seedling vigour index II, respectively, over the control whereas A. flavus caused average per cent reduction of 22.38, 24.23, 41.18, 23.92 and 40.95 in seed germination, seedling length, seedling vigour index I, seedling dry weight and seedling vigour index II, respectively, over the control.

The experiment was conducted at Department of Seed Science and Technology CCS, Haryana Agriculture University, Hisar, Haryana from 2013-15 and comprised of seventeen treatment combinations of manures (viz., FYM and Vermicompost), bio-fertilizers (viz., Rhizobium and PSB) and fertilizers. The freshly harvested fenugreek seeds of all the seventeen treatment plot combinations were stored in plastic containers under ambient conditions up to a period of eighteen months. Seed quality was assessed at a regular interval of six months. A significant decline in seed quality was observed in all the nutrient combinations as the period of ageing increased. It was observed that the treatment combination of Rhizobium and PSB along with 75% Recommended Dose of Nitrogen (RDN) recorded significantly higher germination % (87.33%), seedling length (24.77 cm), dry weight (7.5 mg), vigour index-I (2163) and vigour index-II (657) followed by PSB with 100% RDN and Rhizobium with 100% RDN after eighteen months of ambient storage as compared to control. The electrical conductivity (333 µS cm-1g-1) was also recorded minimum in the treatment Rhizobium and PSB along with 75% RDN followed by PSB with 100% RDN and Rhizobium with 100% RDN after the period of ambient storage while the maximum was recorded in control. The study highlighted that the slightly reduced dose of inorganic nitrogen was best when applied in combination with bio-fertilizer (Rhizobium+PSB) for maximizing the storage potential of fenugreek seed as compared to the rest of treatments.
