Some fruits have difficulties in germination hence their propagation is adversely affected by seed coat dormancy resulting in poor inhibitions and germination potential. This experiment was conducted to determine the effect of pre-treatments on the germination and early growth performance of Moringa oleifera seedlings at nursery stage. The pre-treatment included soaking 24hours, 48 hours, 72hours and control seed not soaked. The experiment was arranged in a Complete Randomize Design (CRD) with four treatments and three replications. A total of 360 seeds (Three replications of 90 seeds) per treatment weresown. The growth parameters such as number of leaves, numbers of branches, stem height, stem width and leaf area were assessed. Data was analysed using descriptive statistics. Germination percentage across the various pre- germination treatments revealed that Moringa seeds soaked for 24hours had the highest percentage germination of 87.7% closely followed by seeds soaked in cold water for 48hours (68.8%). The least percentage germination was observed in Moringa seeds soaked in water for 72hours (53.3%). The results also indicated that pre-treatments of Moringa seeds significantly (P<0.05) improved the performance of the seedlings with regards to number of leaves, branches, plant height, stem width and leaf area with 24hours Moringa oleifera seeds soaked in cold water.

Breaking Seed Dormancy

The purpose of this research was to determine the appropriate methods of breaking seed dormancy, level of water uptake, and the influence of gibberellic acid on the early growth of Tamarindus indica seedlings. The scarification methods used included: concentrated sulphuric acid (H2SO4), manual scarification, flaming, hot and cold water treatments. The experiments were conducted in the laboratory on Petri dishes and in potting media. GA3 was used to optimize the production of seedlings by spraying the solution on the foliage. The treatment for 10 minutes with concentrated H2SO4 gave the maximum germination percentage and water uptake (80.41%). GA3 enhances the growth of the seedlings by increasing the height, the number of leaves and stem girth at eight weeks after sowing. In conclusion, all the scarification treatments applied to the seeds of T. indica proved effective. The ten minutes treatment with concentrated H2SO4 was the best treatment for breaking seed dormancy of T. indica. And gibberellic acid enhanced early and fast seedling growth as it increase height, number of leaves and stem girth of T. indica.

The research work conducted at the Teaching and Research Farm of University of Abuja was aimed at assessing the effect of Moringa oleifera, selected leguminous plants and inorganic fertilizer on the performance of orange fleshed sweet potato in Alley Cropping System. Randomized Complete Block Design (RCBD) using five treatments with three replications was applied. Data collected include: percentage survival of sweet potato, length per vine (cm), number of leaves per vine, leaf area of sweet potato, weed dry matter (g/m2), yield of sweet potato roots. Highest number of leaves (28) per plant was recorded in the control plot while the plots with NPK fertilizer had the highest length per vine (94.55cm) though not significantly (p>0.05) different from others. Higher percent survival (88%) of sweet potato was recorded from control plots. Stands grown in Arachis hypogeae plots produced the highest leaf area (0.202m2) while plots in which NPK fertilizer was applied experienced highest weed dry matter (4.083g/m2) although highest root yield (1.2t/ha) was recorded from the plots with NPK fertilizer.

Vegetables form major part of human dietary/nutritional needs. It provides the necessary vitamins and minerals as well as antioxidants to boost immunity. Different vegetables however have different benefits and require different growing conditions. This study investigated the effect of two growing conditions (Screen-house and open field) and soil amendments; Mexican sunflower compost (MSC; applied at 0, 5, 10 t/ha) and NPK 15:15:15 (applied at 0, 50 and 100 kg N/ha) on the growth performance, yield, and nutritional quality of five selected vegetables (Amaranthus cruentus, Celosia. argentea, Solanum macrocarpon, Solanum nigrum and Solanum incanum). Each treatment was replicated three times and experiment arranged in completely randomized design, Compost was applied a week before seed sowing vegetables grown in the screen-house generally performed better than the open field in terms of leaf area and chlorophyll content. The response however varied based on the vegetable and the soil amendments. Solanum species, performed better than Amaranthus under screen-house than open field. Chlorophyll in the leaf responded positively to NPK fertilizer under screen-house conditions while growth parameters such as plant height, stem girth, number of leaves under screen-house and field conditions varied depending on the vegetables. The number of leaves and leaf area increased with soil amendments. Moisture, crude protein and ash contents were reduced under open field compared to screen-house. The zinc and iron contents of the vegetable leaves showed that addition of compost was superior to NPK and screen-house better than open field. It can be concluded that vegetables grown in the screen-house performed better in their respective growth parameters than vegetables are grown under the open field.

Aims: An experiment was conducted to compare the growth performance of two varieties of Moringa oleifera (wild variety and PKM-1) under different seasonal period at two locations in northern Burkina Faso, and the potential for improving household nutrition. Study Design, Place and Duration of Study: Two separate trials corresponding to sowing period (cold and warm) were laid out at each site (Bani and Tougou) in a completely randomized block design with three replicates between December 2017 and September 2018. Methodology: Each block was subdivided into two plots of 8 m² (separated from each other by 3 m break) intended to receive each variety of Moringa at each sowing period. The seeds were sown with 2 seeds by pit at 2 cm depth with spacing of 0.5 m x 0.5 m in each plot ploughed up to 30 cm. Watering was done daily during the dry season and consisted of applying 24 liters of water in each plot at two times. Vegetative growth measurements (plant height, number of leaves) were done weekly while leaf biomass production was assessed monthly from the 40th day after sowing. Results: The results showed that seedlings growth parameters and foliar biomass differed significantly (p < 0.001) among the two Moringa oleifera varieties and were influenced by the sowing period and sites. Although the two varieties grew well, Moringa oleifera var PKM-1 grew faster and produced much leaves compared to the wild or local variety. Then, greater growth attributes (height and number of leaves) and foliar biomass were noted for PKM-1. Conclusion: The warm period (March / April) appear to be the most recommendable period for the growth and biomass accumulation of the two varieties of Moringa oleifera.

AbstractThis study was carried out to determine effects of salinity on germination and seedling development of commercially important common bean genotypes in Cameroon. The seeds of eight genotypes were used for both trials. The germination experiments were carried out on petri dishes in the laboratory while early growth trials continued in plastic pots in the screenhouse. Both stages were setup using a randomized complete block design with three replications. Germination and early growth trials of the different genotypes were studied using distilled water as control or osmotic potentials of 50, 100, 150 and 200mM NaCl to study the effects of salinity on germination and seedling growth characteristics. Leaf concentrations of Na+ and K+ were determined. At the germination level, germination percentage, germination index and the coefficient of velocity of germination decreased with increasing salinity while the mean germination time and time to 50% germination increased with increasing level of salt. All the growth variables decreased with increasing salinity with the exception of the root length which was not affected by salinity. It was observed that increasing salinity induced a significant increase in leaf Na+ and substantial reduction in the accumulation of K+ in the leaves. For ions accumulation, germination variables and growth parameters, significant differences at 0.001 probability levels were found among salinity treatments, common bean genotypes and most of their interactions. Significant correlations were found between all germination variables and between most growth parameters. From the effect of salt application, the common bean genotypes namely KEBCB049, KEB-CB053 and Mac-33 were the most tolerant while KEB-CB055 and KEB-CB050 were the most sensitive. The results confirm that there is genotypic variation in salinity tolerance and that the most tolerant genotypes should be further explored in selection programs, with the aim that they should be promoted for cultivation in tropical zones affected by salinity.

P. australis, E. crassipes (in mangrove swamp) and S. officinarum (in rainforest) are capable of tolerating some levels of crude oil in soil. However, some important growth characteristics such speedy growths, extensive root system and increased biomass desirable for efficient rhizoremediation are depressed. To cushion this suppressive effects, plants were subjected to the following treatments: Plant + Soil (PS) (Control); Plant + Soil + Oil (PSO); Plant + Soil + Oil + Fertilizer (PSOF); Plant +Soil + Oil + Fertilizer + Microorganisms (PSOFM); and Plant + Soil + Fertilizer + Microorganisms + Solarization (PSOFMS). Treatments were monitored for 120 days to determine their effects on the following growth parameters: Germination, germination percentage, height, and root length, dry weight, and leaf area. Results indicated that treatments PSOF, PSOFM and PSOFMS enhanced all growth parameters over contaminated untreated soil (PSO) with the exception of germination in P. australis and S. officinarum; while root length, leaf area in E. crassipes were statistically the same for PS, PSO, PSOFM and PSOFMS (P ˂ 0.05). Overall, growth enhancement efficiencies of the applied treatments were in the order: PSOFM ˃ PSOF ˃ PSOFMS. Thus, growth of these plants can be enhanced in crude oil contaminated soil by the above treatments for efficient rhizoremediation.

This study was carried out in College of Forestry, Navsari Agricultural University, Navsari, Gujarat. Total 20 clones having age of 5 ½ years were selected for early growth evaluation at field condition. There was a significant variation (P < 0.05) among 20 clones of Eucalyptus for growth parameters viz., tree height, DBH, mid-diameter, form quotient and volume of standing tree. Tree height varied from 18.5 to 23.6 m with DBH range of 11.47 to 16.07 cm. Mid-diameter indirectly helps to assess the tapering of tree and it ranged from 6.99 to 10.57 cm among 20 clones. The form quotient was used while calculation of volume of Eucalyptus clones. The form quotient varied between 0.58 and 0.71 with overall mean of 0.63 at studied site. Volume of standing tree ranged from 0.12 to 0.28 m3. The overall results showed that clones such as C12 (P2045), C17 (B2253), C4 (P413), C8 (P526), C7 (P498), C16 (SRO16) and C11 (P3020) performed superior for early growth attribute and stem form and these clones suggested for large scale plantation in South Gujarat region.

The present investigation was carried out at the Forestry Research Farm, Navsari Agricultural University; Navsari to evaluate the gamma rays at 10 kR, 20 kR and 30 kR induced variability in Jatropha curcas L. on germination, growth and yield for seven Jatropha genotypes (Phule J-1, Urlikanchan, Hansraj, SKN Big, Chhatrapati, Hansot and MPJ-55). The significantly maximum germination percentage (66.96%), seedling survival (74.18%), seedling collar diameter (0.958cm), shoot length (49.442cm), number of leaves per seedling (7.757) and leaf area (37. 58)was observed in Chhatrapati genotype during nursery stage. While low rate of gamma rays treatment (10 kR) had stimulatory effect for germination percentage, seedling survival, seedling collar diameter, shoot length, number of leaves per seedling and leaf area. However, higher gamma rays doses (30 kR) drastically reduced all studied characters. The interaction effect of genotype and gamma rays were significant for number of leaves per seedling. Further, it was not significant in other traits like germination percentage, seedling survival, seedling collar diameter, shoot length and leaf area.
