Response To Water

Laboratory tests and a field experiment were carried out to evaluate the effects of priming methods on seed invigoration and field performance of soybean (cv. ‘Zan’). The field experiment was arranged as split plot based on RCB design with three replications. Irrigation treatments (I1, I2 and I3: irrigation after 70, 110 and 150 mm evaporation from class A pan) and priming methods (water, 3% KH2PO4 and 3% KNO3 for 8 h at 15±1°C) were allocated to main and sub-plots, respectively. Germination percentage, seedling dry weight and field emergence percentage decreased, but mean emergence time increased, due to seed priming. Grain yield under severe water deficit was 29.32% less than that under normal irrigation. Pods per plant, grains per plant and grain yield per plant were significantly enhanced as a result of low stand establishment caused by seed priming. Consequently, biological and grain yields per unit area and also harvest index were statistically similar for plants from primed and unprimed seeds. In general, priming methods had no any beneficial effect on laboratory and field performance of soybean seeds.

`Moss Curled' seeds of parsley (Petroselinum crispum L.) were primed osmotically in polyethylene glycol or matrically in fine, exfoliated vermiculite at –0.5 MPa for 4 or 7 days at 20 or 30 °C with 0 or 1 mm GA3. All priming treatments stimulated and hastened germination. Matric priming resulted in greater germination (89%) than osmotic priming (83%) when seeds were primed for 7 days at 30 °C, but priming agent had no effect on germination percentage following priming at 20 °C or for 4 days. In seeds primed for 4 days at 20 or 30 °C, matric priming hastened germination more than did osmotic priming. Germination was generally less synchronous with matric than with osmotic priming. Increasing priming time from 4 to 7 days increased the rate of germination, but increased germination synchrony only when seeds were primed at 20 °C. Inclusion of 1 mm GA3 during priming had little or no effect on germination. All matric priming treatments (other than 4-day priming) were repeated to assess seedling emergence in a greenhouse (25°C day/22 °C night). Priming increased the percentage, rate and synchrony of emergence, and increased hypocotyl length at 3 weeks after planting. Priming at 30 °C with 1 mm GA3 resulted in the greatest emergence percentage, hypocotyl length, and shoot dry weight. We conclude that matric priming is a satisfactory alternative to osmotic priming of parsley seeds. Chemical name used: gibberellic acid (GA3).

ABSTRACT In order to investigate salinity stress on seed reserve utilization and seedling growth of treated seeds of barley (Hordeum vulgare L.), an experiment was carried out. Factorial experiment was carried out in completely randomized design with three replicates. To create salinity stress, NaCl in osmotic levels at 0 (as control), -4, -8, -12 and -16 bar were used. For seed priming, gibberellin (GA) 50 ppm was used. Our results showed that treatment × drought interaction on these traits: germination percentage, weight of utilized (mobilized) seed, seed reserve utilization efficiency, seedling dry weight and seed reserve depletion percentage were significant. The highest germination percentage, weight of utilized (mobilized) seed, seed reserve utilization efficiency, seedling dry weight and seed reserve depletion percentage were attained from priming by gibberellin at control conditions. Thus, priming increased characteristics as compared to the unprimed. Priming improved seed reserve utilization such as: weight of utilized (mobilized) seed reserve, seed reserve depletion percentage, seed reserve utilization efficiency and seedling growth in barley under salinity stress.

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.

Weeds are unwanted plants in crop that can be control by different methods among them use of aqueous extract of crop is an imperative method. To investigate the allopathic potential of aqueous extract of winter crop Papavare somniferum (opium) on summer weed Echinochloa cruss-galli (barnyard grass) laboratory experiments were conducted. The experiment coomprised seven concentrations (0, 0.25, 0.50, 1, 2, 4, and 8%) of different plant parts i.e., leaves, stem and flower of P. somniferumwere. All the tested concentrations and plant parts of P. somniferum significantly reduced mean emergence time, germination index, germination percentage, time to 50% germination as well as well growth of E. cruss-galliweed. However, maximum mean emergence time (9.07 days), time to 50% germination (3.67 days) was noted at leaves and stem extract, respectively. Application of aqueous extract of stem at 8% concentration resulted in greatest time to complete 50% germination (5.42 days) and lowest fresh weight (6.28 g), dry weight (1.00 g) and root length (0.33 cm) of E. cruss-galli. Whereas leaf extract at 8% concentration produces less shoot length (1.13 cm) and more emergence time (9.18 days). Lowest emergence percentage (6.67%) and germination index (0.89) were produced by aqueous extract of fruit at 8% concentration. On the basis of this experiment, it can be concluded that higher concentration (8%) of stem extract of P. somniferumwas used to biologically control the infestation of E. cruss-galli weed.

Abstract Borage is a valuable medicinal plant with various constituents in leaves, flowers and seeds. Hence, it is important to improve the performance of this medicinal plant under different environmental conditions. Thus, two field experiments were arranged as split-plots based on a RCB design with three replications in 2012 and 2013, to evaluate the effects of seed priming and different irrigation intervals on selected physiological properties of borage leaves. Irrigation intervals (irrigation after 60, 90, 120, 150 mm evaporation from Class A pans, respectively) and priming treatments (control, water, KNO3 and KH2PO4) were allocated to the main and sub plots, respectively. The chlorophyll content index was enhanced under limited irrigation treatments, mainly due to a decrease in leaf area index and intercepting more radiation. However, the membrane stability index was stable under different irrigation intervals. Decreased relative water content and leaf area index and increased leaf temperature under lower water availability led to some reductions in the grain yield of borage. All of the priming techniques, particularly hydro-priming, enhanced the seedling emergence rate, leaf area index and consequently grain yield per unit area. Therefore, seed hydro-priming can be used to improve the field performance of borage, particularly when sufficient water is available.

Two experiments were conducted in the Savelugu-Nanton Municipality of the Northern Region of Ghana in 2012 and 2013 to assess the effect of N fertilizer on growth, N remobilization and grain yield of three local varieties of soybean (Glycine max [L] Merill). The experiments were a 3 x 4 factorial laid in Randomized Complete Block Design (RCBD) with four replications. Factor A was soybean varieties (Jenguma, Quarshie, Ahotor); Factor B was 0, 15, 30 and 45 kg N ha-1. The experimental fields were planted manually on the flat by drilling and later thinned to 2 plants hill-1 at 0.50 m × 0.10 m with a population of about 400 000 plants ha-1. Growth and yield parameters measured were plant height, nodule number plant-1, nodule dry weight plant-1, percent nodule effectiveness, number of pods plant-1, number of seeds pod-1, 100 seed weight, harvest index and grain yield. The results showed that the control recorded lower figures in all growth parameters. Nitrogen remobilization was also observed in all plots, which indicate that soybean needs greater levels of N during grain filling. Again, N remobilization and soybean yield were highest in the 45 kg N ha-1 treatment compared to the other treatments. However, considering the overall yields, farmers in the study area should be advised to adopt starter N fertilization of soybean for higher yields as the soils are highly degraded in soil fertility.

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 Low seed germination and seedling emergence is one of the main problems in saline areas. Seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stresses. The objective of this research was to evaluate the effect of seed priming with NaCl and water on growth and seed reserve utilization of millet seeds under salinity stress. Treatments were combinations of four levels of salinity stress (0, ⊟4, ⊟8 and ⊟12 bar) and three levels of seed priming and control with three replicates. Results showed that with increase in salinity stress, germination components such as germination percentage, germination index, mean time to germination, normal seedling percentage, seedling length, seedling dry weight of utilized (mobilized) seed and seed reserve utilization efficiency decreased, but seed priming showed lower reduction. The highest germination characteristics and seed reserve utilization was obtained by halo-priming in control conditions. It is concluded that priming results in improvement in germination components of millet in salinity stress conditions.
