The objective of this study was to determine the agronomic diversity of gamma-ray at 50 Gray dose   during the phase of embryogenetic callus in napier grass cv Taiwan. This research used a randomized blok design (RBD) of gamma-ray and without radiation elephant grasses (P. purpureum cv Taiwan). There were 51 numbers in irradiated elephant grass, each number three replicated and five plant per number each. Without irradiation control used elephant grass (P. purpureum cv Taiwan); there were 10 clumps in one block and each line number had been repeated three times. Gamma radiation showed no impact on plant height and stem weight (dry weight) at P>0.05, but had a significant effect on number of tillers, leaf length, leaf width, total weight, fresh weight, leaf (dry weight), weight of stem (fresh weight). Gamma ray irradiation selection does not have to generate high output but can be developed on sub optimal soil or extreme weather conditions such as tolerant felling, which requires less high plant.

Weed-competitive cultivars are desired in the wake of growing popularity of organic farming, environmental pollution and evolution of herbicide resistance in weeds. This research work evaluated the weed competitive ability of three forage maize cultivars (ADA-523, AGA and SASA-5) against the noxious weed barnyardgrass (Echinochloa crus-galli (L.) P.Beauv.). The study was conducted in spring 2018 and repeated in summer 2018. Results of this study showed that maize-barnyardgrass competition significantly decreased the growth of forage maize plants. For instance, barnyardgrass decreased the maize plant height by 11.9-16.9%, leaf length by 13.3-20.2%, leaf width by 20.2-27.4%, and number of leaves by 14.3-25.0%. Fresh and dry weights of maize plants were also significantly decreased as a result of weed-crop competition. Barnyardgrass decreased the shoot fresh weight (30.7-60.6%), shoot dry weight (33.3-52.2%), leaf fresh weight (33.4-56.5%) and leaf dry weight (31.9-50.0%) of the maize plants. An interactive effect of weed × maize cultivars was found non-significant. Forage maize cultivars also varied occasionally for their traits. Nevertheless, ADA-523 had a higher plant height, leaf length, leaf width, leaf fresh weight and leaf dry weight than the cultivars AGA and SASA-5. On the other hand, the cultivar SASA-5 had a higher shoot fresh weight, shoot dry weight and root fresh weight than the other cultivars in the study. This research work concluded that the forage maize cultivars in the study did not vary for the weed-competitive ability. Further, barnyardgrass-maize competition could decrease the growth and development of the maize cultivars.

AbstractThe present study was aimed to biosynthesize selenium nanoparticles (SeNPs) and assess their foliar applications to improve the growth of wheat plants under controlled irrigation and drought stress. Bud aqueous extract of Allium sativum L. was used as a reducing and stabilizing agent of SeNPs followed by their optical and morphological characterization by using ultraviolet-visible spectroscopy, scanning electron microscopy, Fourier-transform infrared, and energy dispersive X-ray analysis. Various concentrations of SeNPs (10, 20, 30, and 40 mg/L) were applied exogenously to drought-tolerant (V1) and drought-susceptible (V2) wheat varieties at the trifoliate stage. Under the positive control conditions, plants were irrigated with 450 mL of water/pot (100% field capacity); and under water-deficit environment, plants were irrigated with 160 mL of water/pot (35% field capacity). Remarkable increase in plant height, shoot length, shoot fresh weight, shoot dry weight, root length, root fresh weight, root dry weight, leaf area, leaf number, and leaf length has been observed when 30 mg/L concentration of SeNPs was used. However, the plant morphological parameters decreased gradually at higher concentrations (40 mg/L) in both selected wheat varieties. Therefore, 30 mg/L concentration of SeNPs was found most preferable to enhance the growth of selected wheat varieties under normal and water-deficient conditions.

Growth and the chlorophyll and carotenoid contents were measured in greenhouse-grown yellow nutsedge (Cyperus esculentusL. ♯ CYPES), following treatment with glyphosate [N-(phosphonomethyl)glycine]. Herbicide was applied as a foliar spray at concentrations of 0.1, 1.0, 5.0, and 10.0 mM. After 2 weeks, growth was inhibited, and chlorosis and leaf apex necrosis were observed. Plant height was reduced, leaf fresh weight was decreased by 40%, and leaf dry weight was slightly affected. Rhizome, tuber, and secondary shoot formation was strongly inhibited, but root development was not affected by glyphosate treatment. With the 10-mM treatment, dry weight of the underground system was reduced by 80%. Chlorophyll and carotenoid levels were decreased by 52 and 54%, respectively, following glyphosate treatment.

Turmeric is an important spice crop of Bangladesh. A field experiment was conducted at farmer’s field of North Jhatibunia, Mirzagonj, Patuakhali during April, 2015 to February, 2016. The study was performed to find out the effect of green manure and nitrogenous fertilizer on the growth and yield of turmeric (BARI Halud-2), in coastal region of Bangladesh. In this study different combinations of green manure along with nitrogenous fertilizer were used. There was eight treatment combinations (viz. 7 ton biomass/ha + 100 kg N/ha, 7 ton biomass/ha + 80 kg N/ha, 7 ton biomass/ha + 60 kg N/ha, 7 ton biomass/ha + 40 kg N/ha, 7 ton biomass/ha + 20 kg N/ha, 7 ton biomass/ha, 100 kg N/ha and control). The highest number of leaves per plant (11.67) were recorded by the combined application of 7 ton biomass/ha along with 100 kg N/ha. The highest plant height (80.70 cm) and the longest leaf length (47.33 cm) were recorded by the application of 100 kg N/ha. The highest number of tillers per plant (7.67), maximum number of primary rhizomes per plant (9.00), maximum fresh weight of clump (189.67 g), highest fresh weight of roots (48.01 g), maximum fresh weight of rhizomes (277.70 g), maximum dry weight of clump (20.01 g), highest dry weight of roots (9.25 g), maximum dry weight of rhizomes (67.50 g) and maximum yield of fresh rhizome per hectare (6.64 tons) were recorded by the combined application of 7 ton /ha biomass+ 40 kg N/ha. Highest number of secondary rhizomes per plant (17.00) and maximum number of tertiary rhizomes per plant (7.00) were recorded by the application of 7 ton biomass/ha + 60 kg N/ha. With a few exception, the best performance in terms of growth and yield of turmeric were found from the combination of 7 ton biomass /ha + 40 kg N/ha.
