AbstractSeed priming significantly affects germination and post germination emergence in seedling of plants. Okra is an important vegetable plays significant role in human nutrition. However, little information is available regarding effect of seed priming on germination and post germination early vegetative growth. Therefore, a pot experiment was conducted to find out the effect of seed priming on the emergence and seedling vigor in different okra varieties. Six local Bangladeshi okra varieties were primed in water for 24 hours and evaluated their germination and post germination emergence. The varieties were named as V1-V6 (V1 = Flash power, V2 = Durga, V3 = BARI dheros-2, V4 =Okra pornota, V5 =Dandy all green, V6 = Boishakhi). Post priming evaluation was done based on germination percentage, root-shoot length of seedlings, seedling height, and dry weight of seedlings, germination index and speed of germination at different days after sowing (5-15 DAS). Highest germination was observed in V3 (88.00%) and lowest was in V5 (25.33%). Root length was highest in V3 and V4 (8.77cm) and lowest was observed in V2 (5.15cm). Shoot length of the seedlings was highest in V3 (7.94cm) followed by V1 (7.33). Shoot length of the seedlings was lowest in V5 (5.12cm). Seedling height was highest in V3 (16.71cm) which was followed by V6 (16.26cm). The lowest seedling height was observed in V1 (12.50cm). Dry weight of the seedlings was highest in V3 (2.32g) which was followed in V1 (2.26g). The lowest dry weight was observed in V5 (1.99g). The variety V3 performed better in most of the evaluated parameters and suggested for commercial cultivation.

Early Seedling

Screening of chickpea lines for salt tolerance through seed germination and early seedling growth is crucial for their evaluation. Seeds of 30 chickpea genotypes were germinated on a sand bed irrigated with saline (3, 6, 9, 12 dS/m) and control solutions upto 30 days. At the early seedling stage (25-30 days), germination percentage, chlorophyll content, proline, root length, shoot length and seedling dry weight were found to be affected due to salinity. Salt tolerance index (STI) for plant biomass maintained a significant correlation with chlorophyll, proline, shoot length, and root length, which indicated that these parameters could be used as selection criteria for screening chickpea genotypes against salt stress. Significant differences in shoot length, root length, and seedling dry weight in 30-day-old seedlings were observed among selected chickpea genotypes as well. From the overall observation of germination characterstics and early seedling growth, it is concluded that the chickpea genotypes, HC-1, HC-5, ICC 867, ICC 5003, H-10-41 showed better salt tolerance as compared to the available salt tolerant check variety.

This study aimed to determine the effect of seed priming (on-farm, hydro, halo, osmo, vitamin c priming, and hardening) on the germination and seedling growth of spring rice varieties: hardinath-3, hardinath-1, and chaite-5 at ambient room temperature. A factorial completely randomized design (CRD) was carried out with two factors: methods of priming and varieties at agriculture knowledge center (AKC), kapilbastu during march 2020. There were, in total, 21 treatment combinations and four replications. Parameters observed were germination percentage, speed of germination, vigor index, root length, shoot length, fresh weight, and dry weight of rice seedlings. Hardinath-3 had superior performance in terms of germination percentage (95.35 %), vigor index (183.86), root length (11.51 cm) and shoot length (7.39 cm) compared to hardinath-1 and chaite-5; the speed of germination, however, was greater in hardinath-1. Seed hardening - alternate soaking (tap water for 24 hours) and drying - induced higher germination percentage (94.91 %), speed of germination (96.00), and vigor index (197.43) than did other priming methods; germination percentage of vitamin c primed seeds (94.75 %), nevertheless, were at statistical par with hardened seeds. Hardened hardinath-3 seeds were better in regards to germination percentage (97.50 %) and root length (12.92 cm), while the speed of germination (97.50) and vigor index (210.50) was greater in hardened hardinath-1. Vitamin c primed seeds of hardinath-3 and hardinath-1 were finer with dry weight, shoot length, and vigor index. In conclusion, farmers' are suggested to hardened seeds of hardinath-3 before sowing to promote uniform germination and growth.

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.

Laboratory experiments were carried out to determine the effects of harvesting stages on the seed quality of chickpea. Chickpea seed of three varieties (BARI Chola-5, BARI Chola-6 and BARI Chola-8) were collected at three harvestings times i.e. from three different times at 7 days interval prior to harvesting, viz. i) when the pods were yellowish with a few yellow greens (H1 stage), ii) when most of the pods were light brown with a few yellow (H2 stage), and iii) when all the pods were completely brown and dry (H3 stage). Significant variation was observed in three varieties of chickpea for all the parameters studied except vigour-I. The highest germination percentage, root length, shoot length, root plus shoot length and vigour-II was observed in BARI Chola-5 which was significantly higher over BARI Chola-8. Dry weight was found to be significantly higher in BARI Chola-8 which was identical to BARI Chola-6. Moisture content was significantly higher in BARI Chola-8. Seed collected at the stage when most of the pods were light brown with a few yellow (H2 stage) recorded the highest germination percentage, dry weight, vigour-I and root length. Pods (H1 stage) gave the highest moisture content in seeds. BARI Chola-5 seeds recorded the highest germination at H2 stage. Interaction effects of varieties and harvesting stage had non-significant effect on germination percentage, vigour-I, shoot length and vigour-II in both the years.

The experiment was carried out at the research field of Agronomy and Farming Systems Division, Bangladesh Sugarcrop Research Institute (BSRI), Ishurdi, Pabna during 2012-2013 to determine the most suitable spacing for sugarbeet cultivation in Bangladesh. The experiment was conducted with nine spacing viz. 50 cm × 20 cm, 60 cm × 20 cm, 70 cm × 20 cm, 50 cm × 25 cm, 60 cm × 25 cm, 70 cm × 25 cm, 50 cm × 30 cm, 60 cm × 30 cm and 70 cm × 30 cm in a randomized complete block design with three replications. The effects of spacing on sugarbeet plantation were observed on growth and growth contributing components (germination percentage, number of leaves plant-1, root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, shoot dry weight, crop growth rate) of sugarbeet. The highest germination percentage (95.67%), number of leaves plant-1 (34.33) at 30 DAS, shoot length (54.07 cm) at 120 DAS, root fresh weight (969.47 g plant-1) at 150 DAS, shoot fresh weight (752.47 g plant-1) at 120 DAS and other growth contributing parameters were obtained with the spacing 70 cm × 30 cm. However, the maximum root length (38.97 cm) was obtained with 50 cm × 20 cm spacing. It was concluded that the wider spacing promoted the growth of individual beet, though the optimum spacing for maximum root growth of sugarbeet was 50 cm × 20 cm. Bangladesh Agron.

The present investigation on effect of nitrogen [N0 (Control), N1 (50 kg N/ha), N2 (100 kg N/ha), and N3 (150 kg N/ ha)] and plant growth regulators [G0 (Control), G1 (50 ppm GA3), G2 (50 ppm NAA) and G3 (500 ppm Cycocel)] on seed yield per plant and seed quality parameters in brinjal (Solanum melongena L.) cv. GJB 3 was carried out at the Instructional Farm, Department of Agronomy, Junagadh Agricultural University, Junagadh during kharif 2015-16. The experiment was laid out in field as per randomized block design (Factorial) with three replications. The seed harvested from 16 different treatments combinations replicated thrice from the field were analyzed in the laboratory following completely randomized design (factorial) for various seed quality parameters. Application of nitrogen @ 150 kg N/ha recorded significantly (P<0.05) highest seed yield per plant, shoot fresh weight, root dry weight, shoot dry weight and vigour index – 2 (mass), while application of 100 kg N/ha resulted in significantly (P<0.05) highest germination percentage, root length, shoot length, root fresh weight and vigour index – 1 (length). Application of GA3 at 50 ppm recorded significantly the highest seed yield per plant, germination percentage, root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, shoot dry weight, vigour index – 1 (length) and vigour index – 2 (mass). Among the 16 different treatment combinations, nitrogen @ 150 kg/ha and GA3 50 ppm noted the maximum seed yield per plant, shoot dry weight and vigour index – 2 (mass), while significantly the maxi-mum germination percentage, root length, shoot length, root fresh weight, shoot fresh weight and vigour index – 1 (length) were registered in treatment combination nitrogen 100 kg N/ha and GA3 @ 50 ppm. Therefore, it is advised that application of 100-150 kg of N/ha as a nitrogenous fertilizer and spray GA3 @ 50 ppm (G1) at 45 days after transplanting helps in increasing the seed yield per plant and seed quality parameters in brinjal seed production.

The study was aimed to explore the phytotoxic potential of Sonchus oleraceus L. on the emergence and seedling growth of Echinocloa cruss-galli L. and quantification of allelochemicals present in leaves, stem and fruit of S. oleraceus weed. The experiment comprised of aqueous extracts of leaf, roots and fruits applied at 0.25, 0.5, 1, 2, 4 and 8% (w/v) along with a control (0%). Data regarding seed emergence, emergence index, emergence percentage, root length, shoot length and seedling dry weight was recorded. All the tested concentrations of all parts of S. oleraceus significantly inhibited the seed emergence, emergence index, emergence percentage (%) and growth and delayed mean emergence time and time taken to 50% emergence of E. cruss-galli weed. However, maximum mean emergence time (5.20 days) and time taken to 50% emergence (3.49 days), were noted at 8% concentration of fruit and leaf aqueous extract, respectively. Fruit aqueous extract at 8% concentration caused the lowest germination index (1.70), germination percentage (40%), root length (0.09 cm), shoot length (0.45 cm) and dry weight (0.16 g) of E. cruss-galli. Results suggested that the extract of S. oleraceus weed at concentration (8%) can be used as potential bio-herbicide for the control of E. cruss-galli weed.

Abstract The objective of this study was to evaluate the effectiveness of seed priming in improving seed germination and seedling vigor of Vicia villosa under laboratory conditions. Chemical stimulators included: gibberel-lic acid (125,250 and 500 ppm), salicylic acid (100,200 and 300 mg/lit) and extract of Eucalyptus camaldulen-sis (0, 25, 50, 75 and 100 %). This experiment was carried out as factorial experiment based on a randomized completely design, with four replications. The results showed that Eucalyptus camaldulensis extract had in-hibitive effect on germination and early seedling growth of Vicia villosa. Early seedling growth of Vicia villosa increased by pretreatment of seeds in chemical stimulators so that the highest effect was observed in gibberellic acid (250 ppm). The chemical stimulators don’t have any effect on germination speed. Interaction effects of allelopathic and pretreatment with chemical stimulators were significance on germination percentage, root, shoot and plant length and seed vigor index.

Effects Of Temperature

Puccinecia ciliata is a salt-tolerant, winter-growing grass. The responses of germination of P. ciliata to salinity and temperature were investigated. With a day/night temperature regime of 25/15�C, the final germination percentage of P. ciliata in distilled water was 54%, and was not significantly affected by salinities up to 87 mol m NaCl (osmotic potential, =, -0.4 MPa), but decreased to 5.2% in 260 mol m-3 NaCl (=, -1.2 MPa). The n at which the final germination percentage was reduced by 5O0/n of that in distilled water was about -0.5 MPa, which was similar to that of Lolium perenne. However, for L. perenne, the final germination percentage decreased more rapidly with increasing salinity and from a higher value in distilled water (97%) compared with P. ciliata. Germination of P. ciliata was completely inhibited at constant 33�C and was low (<20%) where day temperature was 30�C and night temperature was greater than or equal to 17�C. Maximum germination was observed where day and night temperatures were between 17 and 24�C, but were not equal. The rate of germination decreased with increasing salinity and was maximal at temperatures between 17�C and 24�C. The reduction in the final germination percentage in NaCl solution was apparently an osmotic effect since the final germination percentage in iso-osmotic solutions of mannitol, polyethylene glycol, NaCl, KC1 and KNO3 were similar. P. ciliala and L. perenne were more salt sensitive during germination than during early seedling growth; for 35-day-old seedlings, shoot dry weight was reduced by 50% of that of the nonsaline treatment when irrigated with solution with = of -0.75 MPa for L. perenne and - 1.25 MPa for P. ciliala.

Background: Drought stress at germination and early growth stages hinders the seedling establishment in chickpea which ultimately affects the economic yield. Such adverse affects of drought can be mitigated by screening and identifying the tolerant genotypes of chickpea which is commonly cultivated under rain-fed conditions during post-rainy season. Methods: Effect of drought stress on germination and early seedling growth of thirty three chickpea genotypes was studied under four different concentrations of PEG 6000 (-0.3, -0.6, -0.9 and -1.2 MPa) along with control and hydration under laboratory conditions during 2018-19. Result: Significant variation was observed among the genotypes for germination, root length, shoot length and seedling vigour index under different concentrations of PEG 6000. Complete inhibition of germination was observed in most of the genotypes at -1.2 MPa. Based on the results obtained, JG 11 and NBeG 3 were considered as tolerant since they showed comparatively higher germination, root length, shoot length and seedling vigour even at -1.2 MPa, while NBeG 723 and NBeG 833 were considered as susceptible genotypes because of their poor germination and seedling growth even at lower levels of drought stress.
