Growth, Yield, Seed and Seedling Quality Parameters of Rapeseed-mustard Varieties under Different Seed Priming Options

Abstract

Rationale: Crop production and quality of produce get affected by drought, stand establishment and low availability of nutrients. Apart from various prevailing methods, seed treatment through priming now-a-days has been found to noticeably improve crop establishment for increasing seed yield and quality.
 Aim: To study the effect of various seed priming options on rapeseed-mustard varieties.
 Place of Study: A field experiment was conducted at AB Block Farm, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal, India during winter season of 2017-2018.
 Methodology: Experiment comprised six rapeseed-mustard varieties (Anushka, Sanchita, TBM-143,TBM-204, Kranti and Pusa Bold) in main plot and five seed priming options (KH2PO4 @ 0.15 mol 100 ml water-1 5 g seeds-1, KNO3 @ 0.1 mol 100 ml water-1 5 g seeds-1, PEG 6000 @ -0.3 MPa 100 ml water-1 5 g seeds-1, hydro priming @ 100 ml 5 g seeds-1 and control) in subplot, replicated thrice in a split plot design. Observations on growth and yield contributing parameters were recorded from the field. Further, various quality parameters of seed and seedlings were evaluated in the laboratory. Data on all the parameters were finally statistically analyzed.
 Results: Among the varieties, Pusa Bold performed better in terms of growth, yield contributing parameters and seed yield under seed priming through either KH2PO4 @ 0.15 mol 100 ml water-1 5 g seeds-1 or PEG 6000 @ -0.3 MPa 100 ml water-1 5 g seeds-1. Seed and seedling quality parameters such as root and shoot lengths, seedling fresh and dry weights, germination % and vigour index were also improved under the same.
 Conclusion: Cultivation of mustard variety, Pusa Bold by seed priming through any of those two chemicals (KH2PO4 or PEG 6000) can be recommended for New alluvial zone of West Bengal, India.

Impact of Foliar Spray of Bioregulators in Terminal Heat Stress Condition on Test Weight, Oil Content and Seed Viability of Mustard (Brassica Juncea L.)

“…Between the two varieties variety Maya (V 2 ) was found to be significantly superior in test weight and oil content except seed viability % this may be because of the freshly harvested seed lot have highest seed quality which may not show significant difference however, maximum test weight (3.91g), oil content (38.38%), seed viability (93.79%) was recorded in V 2 over V 1 . There findings were in accordance with the findings of (Rai et al 2017) who found that performance of mustard varieties in differ each other for seed viability, similar findings were reported by (Das et al, 2020).…”

Correlation of seed vigour with field emergence in lentil varieties (Lens culinaris)

“…These findings differed from Hussaini (1984) [10] in maize & from Singh, (2012) [15] in okra. These variation among varieties are may be due to genetic makeup of varieties or due to the accumulation of food reserves in seeds (Rai et al, 2017) [14] reported that performance of varieties in respect to seed viability, germination %, seedling length, seedling dry weight and seedling vigour index I & II were differ each other similar findings were reported by (Das et al, 2020) [7] .…”

Early Generation Selection Parameters for Genetic Improvement using Morpho-physiological and Seed Yield Components in Brassica species

“…The imperative need for nutritionally rich edible oils is constantly increasing in our daily life due to expanding human population. India ranks fourth largest oilseed producing economy worldwide [2]. Among various oilseed crops in India and the rest of the globe, rapeseed-mustard (Brassica spp.)…”
