Cutting propagation was the system to produce quince nursery trees (Cydonia oblonga). Experiments have been carried out in order to identify news propagations methods. As a result of this research, the 'Japonês' quince (Chaenomeles sinensis) was selected with rootstock, due to its good plant vigor for grafting, rusticity, and adequate performance in the field, mainly in the first years after planting. However, the best grafting period and grafting method must be determined for this rootstock. This research evaluated three grafting methods and five quince scion cultivars on 'Japonês' rootstock. The quince cultivars 'Provence', 'Mendoza Inta-37', 'Portugal', 'Smyrna', and 'Japonês' were grafted by winter cleft grafting, winter budding, and summer budding on 90cm long plants of 'Japonês' quince rootstock seedlings, cultivated in 3-liter plastic bags. Plant growth evaluations started as early as 60 days, and were concluded 150 days after grafting. Cleft grafting resulted in the highest graft survival rate for 'Smyrna', 'Mendoza Inta-37' and 'Japonês' cultivars. Although the higher graft survival rate was recorded in the winter, the buds grafted in the summer had better development.

The experiment on evaluation of open pollinated genotypes of Yard long bean (Vigna unguiculata ssp. sesquipedalis) was conducted during summer season of 2016 and 2017 at Horticulture Research Division, Khumaltar Lalitpur to assess the variability in the genotypes and yield potentiality for commercial production. The experiment was laid out in Randomized Complete Block Design with three replications. Six genotypes viz. Great Wall 01, Great Wall 02, Great Wall 03, Great Wall 04 and Great Wall 08 were compared with Khumal Tane. Observations were recorded on fresh pod yield and yield attributing parameters. The plant vigor and plant uniformity score (1-5 scale) was not found significantly different among the tested genotypes. The highest number of pods per plant (46) was observed on the variety Great Wall 03 and the lowest number of pods (33) on Great Wall 01 followed by Khumal Tane (39). The fresh pod yield was noted the highest with Great wall 03 (24 t/ha) followed by Great Wall 2 (19.4 t/ha). The lowest yield was observed with Khumal Tane (12.7 t/ha). Likewise, Great Wall 03 was found tender whitish with green color when it matures and spongy type of fruit with mid early maturity (85-95 days) along with long harvesting period of 30-35 days. Although Great Wall 02 scored 4.7 in plant uniformity (1-5 scale) and 4.4 in plant vigor (1-5 scale) it was characterized as thick fleshy and whitish green color at maturity with smooth straight type flesh having early maturity (70-80 days) which could gain the demand of the market early compared to most popular Khumal Tane. Thus, among all genotypes Great Wall 03 and Great Wall 02 were recorded best for further evaluation and recommendation.

Soils with highly uniform textural, physical, and chemical characteristics still give rise to crop stand variability. Seed quality is one of the factors adding to yield variability and has become a concern for corn growers. Hybrid seed producers claim that their seeds provide a uniformity in crop emergence and productivity, but they do not always provide detailed studies to support this claim. Based on growers’ concerns, we examined fields planted with three different hybrid varieties and found that 25% to 50% of the stand had relatively weak vigor, where seed variety A showed 15% of seedlings with lower vigor, and varieties B and C had 30% of seedlings with low vigor. These apparent differences in plant vigor prompted us to initiate a cursory investigation to identify how seed size influenced seedling vigor and if the seedling’s microbial profile played a role in the early growth stages of three commonly grown corn hybrids in Ontario. Seeds were separated based on size, prior to conducting a growth room study. Different sizes of seeds from the same seed lot showed significant differences in vigor capacity and related biometric components. Significant differences were also found in their nutritional composition and microbial profiles within the different seed sizes and the roots and shoots of seedlings derived from such seeds. The results clearly indicate that seed size greatly impacts the plant growth and its microbiome, resulting in seedlings with different plant vigor, microbiomes, and performance.

Field studies were conducted to evaluate potential methyl bromide alternatives against nematods in tobacco (Nicotiana tabacum L.). Metham-sodium and dazomet were evaluated respectively under a polyethylene cover as alternatives for methyl bromide in tobacco transplant production over a two-year period (2009-2010). One genera or species of nematodes, tobacco root-knot nematod (Meloidogyne spp.), was evaluated in Qingzhou, Shandong province of China. All of the fumigant candidates were successful in controlling the pest. Another Parameter, plant vigor, was measured too. Metham-sodium 60g/m2, dazomet 80g/m2 and methyl bromide were not significantly different (P=0.05) from each other in the parameters evaluated. Results of this study indicate that Metham-sodium and dazomet are potential methyl bromide alternatives available to growers for use in tobacco parasite nematods control.
