FIELD STUDY OF RESPONSE OF THE ELECTRICAL RESISTANCE OF 2− AND 4-ELECTRODE PLASTER OF PARIS BLOCKS TO VARIATIONS IN SOIL MOISTURE

The influence of grazing on the vegetative cover of fescue grassland in southwestern Alberta was assessed by studying two adjoining sites, one lightly grazed, the other ungrazed. Percentage basal area, yield, water-intake rate, soil temperature, soil moisture, and amount of root material were compared on a paired plot basis.The data showed that light grazing resulted in the development of a richer flora dominated by Danthonia parryi. Protection from grazing appeared to simplify the flora with a trend toward a cover consisting largely of Festuca scabrella. There was little evidence of difference in productivity between the two sites. Cooler and moister conditions prevailed in the upper 12 inches of the soil profile of the ungrazed site as a result of heavy accumulation of mulch. Considerably more root material to a depth of 54 inches was present on the lightly grazed site. The harmful effects of herbage removal, shown by clipping studies, were not apparent in the field study under a light rate of grazing.

Soil Moisture Status

Soil moisture status can be measured using neutron probes, time domain reflectometry, tensiometers, gravimetric methods, and electrical resistance blocks. Most methods have limitations; they may be time-consuming (gravimetric), expensive (neutron probe, time domain), or fixed in place (tensiometer, gypsum block, and neutron probe) (Schmugge, 1980; Weems, 1991). Water management in droughty, urban areas of the country would benefit from identification of a portable, fast, and relatively inexpensive soil moisture measuring device suitable for use in urban lawns and gardens. In this study, we have identified an instrument that may be suitable for this purpose.

Aims: Production of chili (Capsicum annuum Linnaeus; Solanaceae) in rain-fed regions of Nepal during the winter is constrained by the limited availability of soil moisture. Mulching has been a proven tool to conserve soil moisture and enhance yield. A field study was conducted in the winter of 2019 to identify the most suitable mulch that enhances the yield and yield attributing parameters of chili. Study Design: Seven treatments with three replications were evaluated under the randomized complete block design. Among the treatments, rice straw (5 kg/plot) and water reed (5 kg/plot) were used as natural mulches. While, plastic mulches: transparent (25 µ), silver (25 µ), black (25 µ), and black thick (50 µ) (double thickness) were used as synthetic mulches. Only soil with no mulch was the control. Place and Duration of Study: The study was conducted at Bangau, Dang, Nepal from November 2019 to May 2020. Methodology: We measured soil temperature at 10 cm depth using soil thermometer, and calculated soil moisture through oven dry method. Similarly, weight of ten fresh and ten dry fruits was recorded from each plot using an electronic scale. Number of fruits per plant was also counted. All the data were analyzed using ANOVA and means were separated following a post hoc test. Results: The highest soil moisture (18.38%), number of fruits per plant (24.91), fruit fresh weight per ten fruits (59.86 g), and fruit dry weight per ten fruits (14.65 g) were recorded in black thick plastic mulched plots. Furthermore, the lowest fresh weed weight (95.30 g) was also measured in black thick plastic mulched plots. Whereas, the highest soil temperature (18.92°C) was recorded in transparent plastic mulched plots. Conclusion: This study concludes black thick plastic as the most effective among the treatments tested in this study in enhancing yield and yield attributing parameters of chili.
