Physiological process of germination depends on several factors such as temperature, water potential, light and nutrients. A laboratory study was carried out to asses, the effect of different Vermiwash sources on germination and seedling growth of fenugreek. A factorial design was used with four replications. Treatments were factorial of different Vermiwash (water as a control=W0, Vermicompost extract of wheat straw=W1, horse manure=W2, sheep manure=W3, 25% straw + 75% horse manure =W4, 25% straw + 75% sheep manure =W5, 50% straw + 50% horse manure =W6, 50% straw + 50% sheep manure =W7, 25% alfalfa residue + 75% sheep manure =W8, 50% alfalfa residue + 50% sheep manure =W9, 25% chicken manure + 75% straw manure =W10) and two levels of Vermiwash concentration (20% and 40%). Results showed that germination rate was significantly affected by all treatments. The maximum germination rate was observed at concentration of 40 percent of vermiwash with 25% alfalfa residue + 75% sheep manure. The maximum percentage of germination was obtained in 20 percent of vermiwash with sheep manure treatment and concentration of 40% in wheat straw. A significant difference was observed through treatments at 1% level in root length. In addition, root dry weight differed significantly among treatments at the 5% level. Also, a significant increasing was considered in root length by increasing the concentration of vermiwash.

Abstract A laboratory experiment regarding germination and seedling growth test was conducted with three black gram genotypes tested under three salinity levels (0, 75 and 150 mM), for 10 days, in sand culture within small plastic pot, to investigate the germination and seedling growth characteristics. Different germination traits of all black gram genotypes, like germination percentage (GP), germination rate (GR), coefficient of velocity of germination (CVG) greatly reduced, as well as mean germination time (MGT) increased with increasing salt stress. At high salt stress, BARI Mash-3 provided the highest GP reduction (28.58%), while the lowest was recorded (15.79% to control) in BARI Mash-1. Salinity have the negative impact on shoot and root lengths, fresh and dry weights. The highest (50.32% to control) and lowest reduction (36.39%) of shoot length were recorded in BARI Mash-2 and BARI Mash-1, respectively, under 150 mM NaCl saline conditions. There were significant reduction of root lengths, root fresh and dry weight, shoot length, shoot fresh and dry weight in all genotypes under saline condition. The genotypes were arranged as BARI Mash-1 > BARI Mash-3 > BARI Mash-2, with respect to salinity tolerance.

The effects of different salt sources (C Cl2, NaCl, and KCl) and concentrations, as measured by electrical conductivity, (0, "control", 1, 3, 5, 7 and 9 dS m-1) on seed germination and seedling growth of ?Ferro?, ?Obez?, ?RS 841? and ?Strong Tosa F1? pumpkin varieties used as rootstock were investigated in this study. The results showed that germination rate, root length, shoot length, fresh root weight, dry root weight, fresh shoot weight and dry shoot weights tend to decrease when the electrical conductivity of the solution is higher than 5 dS m-1, independent of salt sources and in all of the varieties. Three days after seeding, a germination ratio of 5 % was obtained from RS 841 variety in all salt source and concentrations, while a germination ratio over 50 % was obtained in ?Strong Tosa? variety for the same conditions except CaCl2 salt source. Nevertheless, seeds germinated in medium having high concentrations of CaCl2 had lower germination rate and poor seedling growth, compared to media having the same concentrations of NaCl and KCl. It was concluded that all of the varieties studied were more sensitive to the concentrations prepared using CaCl2 than that of the KCl, and NaCl.

With the increased development of new tall fescue cultivars used in turf, it is important to understand their individual response to herbicide treatment. The effect of prodiamine on tall fescue root dry weight and root length of selected tall fescue cultivars was studied in the greenhouse in 1.3-m-deep pots of calcined clay. Prodiamine at 0.8 kg ai/ha did not significantly affect either root dry weight or root length. However, the mean root dry weight and maximum root length averaged over all cultivars were significantly reduced at 4 wk after treatment with 1.7 kg/ha. When the prodiamine treatments were repeated in a second experiment, both rates caused a significant reduction in the mean root dry weight and maximum root length but there was no significant difference between prodiamine rates. Single degree of freedom contrasts between the untreated and treated turfs for each cultivar had some differential response in root dry weight. The reduction in root dry weight in the prodiamine treatments was more pronounced in the second study because the turf was less mature. ‘Olympic’ and ‘Rebel’ tall fescue had significantly reduced root dry weight at the 1.7 kg/ha rate in first study; whereas, ‘Amigo,’ Olympic, ‘Sundance,’ and ‘Taurus' tall fescue had significant reduction in root dry weight at both 0.8 and 1.7 kg/ha prodiamine rates. ‘Midnight’ Kentucky bluegrass had significantly reduced root length at both prodiamine rates in the second experiment but in general there was little difference among tall fescue cultivars treated with prodiamine.

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.

Seed priming is a pre-sowing treatment used to reduce stress effects in crops .This technique has been used to increase the germination rate of seeds mainly under unfavorable environmental condition. Crop productivity faces many problems like that unavailability of suitable condition that causes unbalanced seedling growth and poor germination. Hormones are essential to improve plant growth, development, crop yield quality and quantity. Auxin is essential hormones that improves germination of seeds and reduce stress effects. Laboratory experiment was conducted to study the effect of seed priming using different concentrations of IAA and IBA on carrot seeds (Daucus carota). In laboratory experiment, three concentrations of IAA and IBA (75 ppm, 50ppm, 25ppm) treated with distilled water with priming duration of 24 hours. Experiment was laid out in CRD with three replications. Data was collected to investigate the effect of seed priming with IAA and IBA under these condition like that (fresh weight, dry weight, speed of germination, root length, seed length, seedling length, final germination rate, mean germination time and dry matter content). Maximum fresh weight, final germination percentage, seedling length, energy of germination, speed of germination and mean germination rate was recorded IBA 75ppm. Maximum dry weight and dry matter content was observed IBA 25ppm.Maximum shoot length was recorded IBA 50ppm. Non-significant difference was recorded in root length.

A pot experiment was carried out at the Laboratory of Department of Agronomy, Hajee Mohamad Danesh Science and Technology University (HSTU), Bangladesh during 2016 to evaluate the response of maize varieties at germination and seedling growth stages under salt stress. The seeds of the BARI (Bangladesh Agricultural Research Institute) developed four maize varietiesviz.Barnali, Khoi Vutta, Mohor and BARI Maize 5 were placed in plastic pots (each of 25 cm length and 12 cm width) on sand bed irrigated with tap water (control), 100 and 200 mM NaCl salt solutions. It was replicated in thrice with completely randomized design (CRD). Salinity stress significantly affected the germination characters and seedling growth parameters of maize varieties. The germination percentages (GP) and germination rate (GR) reduced significantly with increasing salinity, and the variety Khoi Vutta showed the highest GP and GR followed by Barnali and Mohor showed the lowest GP and GR followed by BARI maize 5. Under high salinity level, seedling growths characteristics like shoot and root lengths, fresh and dry weight of shoot and roots reduced remarkably in the variety Mohor indicating salt susceptible while the minimum reduction of the aforementioned traits was observed in the variety Khoi Vutta demonstrating high salt tolerant variety. The studied varieties can be ranked on the basis of salt tolerance as Khoi Vutta > Barnali > BARI Maize 5 > Mohor from the experiment.

Abstract This study aims to determine the effect of the application of plant growth regulators and osmoconditioning treatment to improve the germination of true shallot seeds. This research was conducted in Asam Kumbang, Medan Selayang, Medan, Indonesia. The research method was a Randomize Block Design with 2 factors, the first factor is Plant Growth Regulators (Z) with 6 levels, namely Z0 (Without PGRs Application), Z1 (Gibberellin 500 ppm), Z2 (Putrescine 15 ppm), Z3 (Putrescine 20 ppm), Z4 (Putrescine 15 ppm + Gibberellin 500 ppm), Z5 (Putrescine 20 ppm + Gibberellin 500 ppm). The second factor was the osmoconditioning treatment with Polyethylene Glycol (PEG) 6000 (O) with 4 levels, namely O0 (Without Osmoconditioning Treatment), O1 (PEG 6000 3%), O2 (PEG 6000 4%), O3 (PEG 6000 5%). Parameters observed were germination rate, germination rate index, percentage of germination, germination ability, simultaneous growth of seeds, seedling length, root length, seedling dry weight, and catalase activity test. The results of this study were: application of plant growth regulators could improve true shallot seed germination, indicated by the observed values of all parameters which were significantly different from those of the control (without PGRs application). The plant growth regulator that produced the best increase in germination was Gibberellins 500 ppm, although the difference in effect with other PGRs was not significantly different. Meanwhile, the osmoconditioning treatment with PEG 6000 was also able to improve the germination of true shallot seeds as indicated by an increase in most of the observed parameters, but in the root length parameter it was seen that the tendency of PEG 6000 3% always gave the highest value but gave the lowest value for this parameter. The best concentration of PEG 6000 in the osmoconditioning treatment to improve true shallot seed germination was 3%.

A field experiment was established on Coto clay (Typic Eutrustox) to evaluate the use of chicken manure as fertilizer for papaya. Four manure rates (0, 5,10 and 15 t/ha) were evaluated in all possible combinations with four rates of inorganic fertilizer (0, 56, 112 and 224 g/plant/month of 15-15-15). Fresh and dry weight of papaya leaves (petioles and blades) increased significantly with manure applications, but no effect of inorganic fertilizer treatments was observed. Phosphorus and potassium concentration in papaya blades was higher in plots receiving 15 t/ha of chicken manure. Fertilizer applications increased K content in blades and decreased magnesium content. Both manure and fertilizer treatments increased fruit yield. The application of 10 and 15 t/ha of manure resulted in fruit yields of 42.19 and 54.76 t/ha. These yields were significantly higher than the yields obtained with the 0 and 5 t/ha treatments. The 0, 56,112 and 224 g/plant/month fertilizer treatments resulted in fruit yields of 28.11, 42.60, 37.22 and 38.25 t/ha, respectively. The yield of the 0 fertilizer treatment was significantly lower, but no significant difference was observed among the other fertilizer treatments. Chicken manure applications increased soil available phosphorus (Bray 1-P) from 16.57 to 28.64 mg/kg, and soil exchangeable potassium from 0.12 to 0.19 cmolc/kg. Fertilizer applications had no significant effect on these two parameters. A significant correlation was observed between papaya yield and Bray 1-P. A Pearson correlation coefficient of 0.65 was obtained when both manure and inorganic fertilizer plots were considered. The correlation coefficient increased to 0.82 when only manure-treated plots were considered, but decreased to 0.25 when only fertilizer-treated plots were considered. Manure applications were more effective in increasing soil available phosphorus than fertilizer applications. Manure applications apparently prevent phosphorus fixation on Coto clay, increasing soil available phosphorus and thus favoring higher fruit yields.
