“…The literature also suggests that the physico‐chemical properties of soil vary depending upon existing land use and its management regimes (Chisanga et al, 2018; Juhos et al, 2019; Silva‐Olaya et al, 2022). The observed range of BD, porosity and pH in this study corroborates well with the previous studies on various land use systems ranging from agricultural, horticultural, pasture, fallow/wasteland to rangeland of the NWH region (Bargali et al, 2019; Bargali & Bargali, 2020; Debnath, Narayan, et al, 2020; Loria et al, 2016; Meena et al, 2018). Soils of temperate fruit orchards had significantly ( p < 0.05) lower BD over FL and BL lands, averaged over soil depths (Figure 2a).…”

“…Since porosity is inversely related to BD (Bargali & Bargali, 2020), the plausible explanations discussed for the variability of BD between land use and soil depths are somewhat applicable to porosity (Figures 2b and 3b), as well. Soil pH, averaged over depths, did not alter significantly (p > 0.05) between the land uses (Figure 2c) and these soils can essentially be categorized as slightly acidic to near neutral in soil reaction Pareek et al, 2019).…”

In recent years, soil fertility in the Northwestern Himalayan (NWH) region has deteriorated partly due to accelerated soil erosion but mainly due to ineffective nutrient management for field crops. However, it is largely unknown whether long‐term temperate fruit farming has adverse effects on the soil fertility in NWH or not. Therefore, we conducted a study with the purpose of evaluating the impact of different land uses in the NWH ecosystem, namely: peach orchard (PO), apple orchard (AO), fertile‐fallow land (FL), and barren land (BL) on soil physico‐chemical characters, nutrient storage capacity, and soil quality index (SQI), along a soil‐depth gradient. A total of 116 composite soil samples [four treatments (i.e., land uses), 4‐ soil depths (0–0.2, 0.2–0.4, 0.4–0.6, and 0.6–0.8 m) and 5, 9, 9, and 6 replications for PO, AO, FL, and BL systems, respectively] were collected for laboratory analyses. Across depths, the soils under temperate fruit plantations had better soil physical conditions (i.e., lower bulk density and higher porosity) over FL and BL lands. The soils in this study can be categorized as slightly acidic to near neutral in soil reaction. Soils under temperate fruit plantations (PO and AO), averaged over depths, had significantly (p < 0.05) less quantity of soil organic C, available nutrients (i.e., primary‐, secondary‐, and micro‐nutrients), nutrient storage capacity, and indices of soil quality, as compared to FL lands. These unfavourable effects were augmented in subsoils (0.2–0.8 m) than topsoils (0.0–0.2 m) affecting secondary‐ and micro‐nutrients more than primary‐nutrients. Results further revealed that these lands display a less favourable (i.e., very high) C:N ratio that could easily be degraded if brought under intensive farming. Restoration of depleted soil fertility in temperate fruit‐tree‐based ecosystems of NWH could be achieved through incentive‐based building‐up of soil organic matter and adoption of a soil‐test‐based nutrient management regime.

“…Population load, poverty, agricultural expansion and intensification, and development of infrastructure have been suggested as major threats to soil structure and biodiversity [ 1 , 2 , 3 ]. Due to the above-mentioned disturbances, land-use systems have been affected adversely in terms of microbial activities, nutrient cycling, and reduced the soil productivity [ 4 , 5 , 6 ].…”

The application of organic manures was found to be beneficial, however, the integrated use of organic manures with chemical nitrogen fertilizers has proven more sustainable in increasing the photosynthetic attributes and grain yield of the winter-wheat crop. A multi-factor split-plot design was adopted, nitrogen and manure fertilizer treatments were set in the sub-plots, including nitrogen-gradient treatment of T1:0 kg N ha−1, T2:100 kg N ha−1, T3:200 kg N ha−1, and T4:300 kg N ha−1 (pure nitrogen -fertilizer application) The 25% reduction in nitrogen combined with the manure-fertilizer application includes T5:75 kg N ha−1 nitrogen and 25 kg N ha−1 manure, T6:150 kg N ha−1 nitrogen and 50 kg N ha−1 manure, and T7:225 kg N ha−1 nitrogen and 75 kg N ha−1 manure. The maximum results of the total chlorophyll content and photosynthetic rate were 5.73 mg/g FW and 68.13 m mol m−2 s−1, observed under T4 in Zhongmai 175, as compared to Jindong 22 at the heading stage. However, the maximum results of intercellular CO2 concentration were 1998.47 μmol mol−1, observed under T3 in Jindong 22, as compared to Zhongmai 175 at the tillering stage. The maximum results of LAI were 5.35 (cm2), observed under T7 in Jindong 22, as compared to Zhongmai 175 at the booting stage. However, the maximum results of Tr and Gs were 6.31 mmol H2O m−2 s−1 and 0.90 H2O mol m−2 s−1, respectively, observed under T7 in Zhongmai 175 as compared to Jindong 22 at the flowering stage. The results revealed that grain yield 8696.93 kg ha−1, grains spike−1 51.33 (g), and 1000-grain weight 39.27 (g) were significantly higher, under T3 in Zhongmai 175, as compared to Jindong 22. Moreover, the spike number plot−1 of 656.67 m2 was significantly higher in Jindong 22, as compared to Zhongmai 175. It was concluded from the study that the combined application of nitrogen and manure fertilizers in winter wheat is significant for enhancing seed at the jointing and flowering stages. For increased grain yield and higher economic return, Zhongmai 175 outperformed the other cultivars examined. This research brings awareness toward the nitrogen-fertilizer-management approach established for farmers’ practice, which might be observed as an instruction to increase agricultural management for the winter-wheat-growth season.

Kumar & Tiwari, 2017;Padalia et al, 2022;Vibhuti et al, 2020). Ecological and socioeconomic factors including geographic area, weather, water accessibility, homegarden size, agricultural policy, market needs and household aspects are determining factors influencing the diversity and utilization of products obtained from the traditional homegardens (K.

The aim of the present study was to analyse the species utilization pattern and their relative prevalence in homegardens varying in size and altitude. Four sites were selected along an altitudinal gradient viz., very low (up to 350 m), low (350-700 m), mid (700-1500 m) and high altitudes (above 2000 m) in Kumaun Himalaya, India. At each altitude, homegardens were categorized into three size classes viz., large (above 0.007 ha), medium (0.004-0.006 ha) and small homegardens (up to 0.003 ha). Maximum species richness was recorded in large sized homegarden at all altitudes except mid altitude where maximum species was observed in medium sized homegardens. Across altitudes, maximum plant species (39) was recorded at mid altitude whereas minimum species (24) were present in high altitude homegardens. Amaryllidaceae was the most important family followed by Oxalidaceae across all the altitudes. In case of plant utilization pattern, maximum species were utilized as a medicine (44.23 %) followed by vegetables (26.66 %), fodder (18.1 %), miscellaneous (15.97 %), spices (13.97 %) and fruits (12.34 %). Among the species, A. cepa (1380) and C. annuum (1026) showed most prevalence whereas S. cumini (278) was the least prevalent species. Across the altitudinal gradient, mid altitude showed most (2341, 1330) relative prevalence whereas high altitude showed least (876, 0) relative prevalence for A. cepa and M. indica, respectively. Management practices and conventional activity could show a higher effect on species composition and their utilization pattern to improve food security and conserving plant genetic diversity in altitudes.
