Abstract: Maize (Zea mays L.) seed production is directly related to the quality of seeds obtained from parental inbredlines. Storage duration is an important factor that can determine quality of any crop seed. This research was conducted with the objectives of to assess the effects of storage duration on seed germination, vigor and seedling emergence of different maize inbredlines stored for variant years. The experiment evaluated the effect of five (ML395, CML202, CML165, CML312 and A7033) inbred lines and three seed storage durations of uncontrolled environment (5, 17 and 29 months) infactorial combinations and arranged in laboratory and lath house using a completely randomized design (CRD) with four replications, conducted in 2017/18main cropping season. The result of analysis of variance was showed significant at (P < 0.005) seed physical quality viz seed moisture content and thousand kernel weight was significantly affected by the two main effect and seed physiological quality parameters like germination percentage, speed of germination, field emergence index, seedling vigorindex-I and II was significantly affected by two main factors and former combinations of the treatment at P < 0.005 respectively. The results of this finding showed that as seed storage duration increased beyond five months, physical and physiological quality parameters of seed become declined. Thus storing seed of maize inbredline for beyond five months are reduce the quality parameters. For that storing seed for short period of time to maintain its quality is preferred.

Abstract: In the present study upon experiment was conducted where the influence of sunlight on the Growth and Yield of aloe Vera plant in summer. A pot experiment was performed in sindh agriculture university tando jam, sindh, Pakistan, during the period from march 2022 to June 2022 to quantify the influence of sunlight on growth and yield of aloe vera plant in summer to different shadows. The trial was laid out at Sindh Agriculture University, Tando jam, Sindh, Pakistan. The plants about 3 months olds of aloe vera plant were transplanted in earthen pots and placed at different shadows, T0 plant kept at sunlight, T1 plant kept in shadow, and T2 aloe vera plant was kept in sunlight for 5 to 7 hours. Outcomes found out that the tremendous variant was found for the special increase contributing characters of aloe vera plant in summer due to T2 aloe vera plant was kept in sunlight for 5 to 7 hours. The highest length of leaves about (18 inches), greatest number of leaves per plant (16), greatest number of suckers / plant (7), and highest wirth of leaf of aloe Vera (4 inches), highest weight of leaf (335 g), highest weight of leaf gel (275 g) was found from the (T2), Alternatively, the lowest length of leaves (13 inches), or lowest number of leaves (12), lowest number of suckers per plant (4), and the lowest worth of leaves (3.2 inches), lowest weight of leaf (290 g), lowest weight of leaf gel (145 g) result was observed from the T0 plant kept at sunlight, and middle results was observed from the T1 such as the length of leaves (14.4 inches), number of leaves (14 ), number of suckers per plant (5), and wirth of leaf (3.4 inches), weight of leaf (300 g), weight of leaf gel (200 g).

Abstract: Air pollution is a very complex problem in the oil-bearing region of Niger Delta and poses multiple challenges in management and mitigation. This study is aimed at providing air quality monitoring plan and adaptation strategies for the residents of three oil bearing communities. Air quality data of the area was collected from NASA after a field study to determine the coordinates of the study area. After downloading the data, the latitude, longitude, and concentration data had to be extracted from the set of data using a computer high level language called python. The data formats gotten in this research were netcdf4, he5, and hdf. The techniques of analysis used were descriptive in the form of tables and trend analysis. Furthermore, geospatial analysis was carried out to note the spatio-temporal hot and cold spots in the area. The hot spot analysis tool calculates the Getis-Ord statistic for each geo-referenced household. This tool identified those households with either high or low attribute values that cluster spatially. In conclusion, wind and human activities greatly influence the pollutants distribution in the study area. Across these communities, Mgbede community is the cold spot region in both seasons while Ebocha is a hot spot region during the dry season and Okwuzi a hot spot region during the rainy season. Again, the concentration of HCHO increases across the three communities during the wet season, while that of PM2.5 decreases in the three communities during the wet season. In a related development, the concentration of SO2 across the three communities decreases during the dry season. Thus, this study proposed monitoring and adaptation plan to atmospheric pollution in the study area by the residents.
