Agronomic management exhibits great influence on growth and yield of crops by modifying physical, chemical and biological properties of soil and plants. Field experiment was conducted during June to December, 2018 to assess the effect of agronomic management viz. light intensity, application of manuring and weed management on soil microclimatic variations and its effects on root yield of Sida hemp (Sida alnifolia L.). The treatments included two levels of light intensity (open and 50 per cent shade), two levels of manuring (no manure and FYM@10 t ha-1), and four weed management practices (black polythene mulching, organic mulching with paddy straw @ 5 t ha-1, hand weeding at 1,3,5 MAP (Month after planting) and no weeding). Higher soil temperature at 10 cm depth was observed in open condition and under black polythene mulching throughout the growing period. Higher soil moisture content at 15 cm depth was recorded under shade and black polythene mulching. Black polythene mulching resulted in increase in soil temperature and soil moisture content by almost two percent as compared to bare soil in open condition. The highest root yield of 14.66 t ha-1 was noticed in plots with black polythene mulching with FYM under open condition. Soil temperature and light intensity showed positive correlation with root yield.

“…Here, the root biomass of P. yunnanensis showed a decreasing trend with the increasing shading levels. Previous studies have shown that soil moisture, shade, and planting methods can stimulate root growth and enhance a species’ invasive ability [ 54 ]. Based on these results, we found that the biomass of P. yunnanensis may be reduced in the underground part and transferred to the aboveground part with different levels of shading.…”

Pinus yunnanensis is an important component of China’s economic development and forest ecosystems. The growth of P. yunnanensis seedlings experienced a slow growth phase, which led to a long seedling cultivation period. However, asexual reproduction can ensure the stable inheritance of the superior traits of the mother tree and also shorten the breeding cycle. The quantity and quality of branching significantly impact the cutting reproduction of P. yunnanensis, and a shaded environment affects lateral branching growth, development, and photosynthesis. Nonetheless, the physiological characteristics and the level of the transcriptome that underlie the growth of lateral branches of P. yunnanensis under shade conditions are still unclear. In our experiment, we subjected annual P. yunnanensis seedlings to varying shade intensities (0%, 25%, 50%, 75%) and studied the effects of shading on growth, physiological and biochemical changes, and gene expression in branching. Results from this study show that shading reduces biomass production by inhibiting the branching ability of P. yunnanensis seedlings. Due to the regulatory and protective roles of osmotically active substances against environmental stress, the contents of soluble sugars, soluble proteins, photosynthetic pigments, and enzyme activities exhibit varying responses to different shading treatments. Under shading treatment, the contents of phytohormones were altered. Additionally, genes associated with phytohormone signaling and photosynthetic pathways exhibited differential expression. This study established a theoretical foundation for shading regulation of P. yunnanensis lateral branch growth and provides scientific evidence for the management of cutting orchards.

“…This might be due to the reason that the growth rate of the plants was higher at the beginning, which exceeded the supporting capacity of SM. The rapid growth of vegetation coverage may lead to insufficient SM content [48]. Previous research results showed that the infiltration rate of alpine grassland with high vegetation coverage was 125%, which was higher than that of grassland with low vegetation coverage [49].…”

Soil moisture is one of the most critical soil components for sustained plant growth and grassland management. Unmanned aerial vehicles (UAVs) are gradually replacing manual labor in various aspects of grassland management. However, their potential for monitoring soil moisture in grasslands remains largely unexplored. High vegetation coverage and frequent rainfall in the Tibetan Plateau pose a challenge for personnel working in alpine meadows. To explore the potential of UAV technology for soil moisture detection in these areas, we conducted a rainfall reduction experiment in Maqu County, China to understand the relationships among soil moisture, vegetation coverage, and visible-light images captured using UAVs. The findings indicated a significant correlation between topsoil moisture and the brightness values in visible-light images acquired by UAVs (p < 0.0001). These results demonstrated that visible-light brightness, vegetation coverage, rainfall reduction, and aboveground biomass can be utilized for estimating the topsoil moisture using these images (y = −0.2676 × Brightness + 0.2808 × Vegetation coverage −0.1862 × Rainfall reduction + 0.1357 × Aboveground biomass + 37.77). The model validation worked well (E = 0.8291, RS = −3.58%, RMA = 10.38%, RMSE = 3.5878, Pearson’s r = 0.9631, PSI = 0.0125). This study further addresses the problem of topsoil moisture measurement in flat areas of mesoscale moist alpine meadows and is expected to facilitate the widespread adoption of UAV use in grassland ecology research.
