Nazmul Hasan Mehedi Avijit Halder Md. Fakhrul Hasan Nowrin Islam Toma Md. Abdur Rouf Jannatul Farthouse Md. Aktarul Islam <p>The demand for healthy and ready-to-eat products has been growing steadily over the years. However, these products are very susceptible to spoilage and have a short shelf-life. In this research, edible coatings based on edible starch (aloe vera gel) and NaHCO<sub>3</sub> were applied on fresh-cut vegetable samples (carrot and potato), and the changes in their bio-chemical properties and microbial changes were monitored during 6 days of storage at 4ºC. Two factor experiments, Factor A; postharvest treatments (different concentration of aloe gel and NaHCO<sub>3</sub>) and Factor B; two vegetable species (Carrot and Potato) were laid out in a Completely Randomized Design (CRD) with three replications. Different concentration of aloe vera gel and NaHCO<sub>3</sub> solutions were prepared as per treatment. The prepared slices of vegetable species were treated with different treatment combinations and stored in 200 g capacity polyethylene bags sealed under air, vacuum or modified active atmosphere and then bio-chemically (Titratable Acidity (TA), Ascorbic Acid (AA) content, Total Soluble Solids (TSS), Reducing Sugar (RS), Non-reducing Sugar (NRS), pH) and microbiologically assessed. Higher rate of edible starch (30%) + NaHCO<sub>3</sub> (2%) treated potato (CT<sub>12</sub>) showed the superior performance on TA (1.290), TSS (5.200% Brix), NRS content (0.340) and pH (4.773% Brix) compare to control and other interaction treatments of the study at 6 days after storage while&nbsp; untreated potato (T0) showed statistically lower AA (6.575 mg/25 g) TA (0.464) TSS (3.856), pH (3.827) NRS (0.133). Growth of bacterial colonies on NA media had statistically highest (14.00) in untreated potato and lowest (5.00) in T<sub>12</sub> treated potato while fungal colonies on PDA media range of 4.00 to 11 at 6 DAS. The study may help small-scale establishments to increase the shelf-life of minimally processed vegetables.</p> 2020-06-25T00:00:00+00:00 ##submission.copyrightStatement## Influence of Seed Size on Seedling Emergence, Growth and Yield of Potted Groundnut (Arachis hypogea L.) 2020-07-06T04:35:08+00:00 Oyewole, Charles Iledun Aminu Patience <p>Pot experiments were conducted at the Faculty of Agriculture, Kogi State University, Anyigba, Kogi State in the Southern Guinea savannah ecological zone of Nigeria to evaluate the influence of seed size on plant performance with reference to seedling emergence, seedling growth, development and yield components and yield of groundnut (<em>Arachis hypogea</em>). The treatment consisted of three different seed sizes: small, medium and large seeds apportioned to a Randomized Complete Block Design (RCBD) with ten replications. For seed size, the seeds were initially graded into small, medium and large seeds based on visual assessment for length and diameter and from each group 100-seed weight was determined thus 100-seed weight became the parameter for measuring seed size as used in this experiment. The analyzed data showed no significant effect of seed size on groundnut canopy height, leaf number, leaf area, stem girth, days to first flower, number of pods / plant, pod weight, and shelling percentage, but significantly influenced mean days to seedling emergence, days to 50 percent flowering, 100-seed weight and taproot length. The significant effect of seed size on days to seedling emergence, days to 50 percent flowering, 100-seed weight and taproot length could significantly influence farmers’ opinion in the choice of seeds used in planting a field; as this could determine crop maturity, grain yield/ha while length of tap root could affect depth of root forage for nutrients and water, thus crop survival. Despite the non-significant effect of the treatment (seed size) on most parameters investigated, generally crop performance increased with seed size and <em>vice versa</em>, thus sowing of larger seeds is recommended for better groundnut performance.</p> 2020-06-25T00:00:00+00:00 ##submission.copyrightStatement## Growth, Yield and Biochemical Characteristics of Tomato (Solanum lycopersicum L.) Genotypes under Seasonal Heat Stress 2020-07-06T04:25:14+00:00 T. R. Chapagain A. K. Shrestha M. D. Sharma K. Mishra Tripathi A. Srivastva <p>This field study was conducted to evaluate yield and fruit quality of tomato genotypes under seasonal heat stress condition (April-June) in plains of Chitwan valley, Nepal for two consecutive years in 2018 and 2019 at research farm, of Agriculture and Forestry University, Rampur, Nepal. Nine tomato genotypes were evaluated for their morphological, flowering, yield and biochemical traits in a randomized complete block design with four replications. Results showed significant differences (P = 0.05) among all genotypes for all traits evaluated. Genotypes AVTO-9304 and AVTO-9801 were early flowering and flowered within 28 days after transplanting. The highest marketable fruit yield of 110.6 and 92.6 t ha<sup>-1 </sup>was recorded in genotype TO-1057 in 2018 and 2019, respectively with the mean yield of 101.6 t ha<sup>-1</sup>&nbsp; whereas genotype AVTO-9802 produced&nbsp; the lowest fruit yield in both years (34.0 and 32.0 t ha<sup>-1</sup> in 2018 and 2019, respectively) with the mean yield of&nbsp; 32.9 t ha<sup>-1</sup>.&nbsp; The highest amount of total soluble solid content (4.90 <sup>o</sup>Brix) was observed in genotype AVTO-9803. Genotype ‘AVTO-1314’ had a significantly higher amount (12.60 mg 100 g<sup>-1</sup>) of ascorbic acid but statistically at par with AVTO-9801, TO-1057 and Pariposa-4102. This study identified genotype TO-1057 as a highly productive genotype suitable for cultivation during summer months in Chitwan and this genotype could be promoted in other agro-ecological regions having the similar climatic conditions.</p> 2020-07-06T00:00:00+00:00 ##submission.copyrightStatement##
