“…These results are in confirmatory with the studies of Robinson (2007), Lordan et al (2018) and Reig et al (2019), who reported maximum TCSA and crown volume per tree at wider spacing and minimum under close spacing in apple. Similarly, Dhiman et al (2018) recorded that the tree growth parameters like tree height spread, annual shoot growth, scion and stock girth, and tree volume was highest in low planting density of 2666 trees ha .…”

“…Tree height, spread and volume, annual shoot growth, scion and stock girth, tree volume, leaf area and pruning wood weight was found more in planting densities of 2666 trees ha compared to the other planting densities. The -1 larger tree size in lower densities might be due to the more availability of space for vegetative growth of the trees and lack of competition for the nutrients, water and light, while smaller tree size in higher densities may be due to the more competition for nutrients and water (Dhiman et al 2018). These results are in confirmatory with the studies of Robinson (2007), Lordan et al (2018) and Reig et al (2019), who reported maximum TCSA and crown volume per tree at wider spacing and minimum under close spacing in apple.…”

The experiment laid out in a randomized block design (factorial) had treatment combinations of three planting density, two training systems and fertigation doses of 100 and 75 per cent of AD (NPK). The results revealed that trees planted at a density of 2666 trees ha -1 registered highest annual shoot growth, increase in tree height, spread, scion girth, and volume. The lowest tree growth was recorded in high density planting of 5333 trees ha . The results showed a positive relationship between productivity and planting density. The productivity -1 increased with increasing density, while yield per trees decreased. Among the training systems, vertical axis trained trees reported the highest annual shoot growth, increase in tree height, spread, scion girth, and volume and the lowest tree growth was observed in vertical axis system. However, the maximum productivity was registered by the trees trained with Tall spindle system and the minimum was noted in vertical axis system. In case of fertigation, significantly highest tree growth parameters and productivity was registered by the trees subjected 100 % AD (NPK). Among three factors interaction, the highest tree growth parameters were recorded in trees planted at density of 2666 trees ha , trained -1 with vertical axis and subjected 100 % AD (NPK).

Three fast-growing trees, viz., Populus deltoides, Eucalyptus spp. and Casuarina equisetifolia were studied, in high-density plantation at Padilla, Prayagraj, Uttar Pradesh with following treatments viz., T1: Poplar (1×1m), T2: Eucalyptus (1×1m), T3: Casuarina (1×1m), T4: Poplar (1.2×1.2 m), T5: Eucalyptus (1.2×1.2 m), T6: Casuarina (1.2×1.2 m), T7: Poplar (1.5×1.5 m), T8: Eucalyptus (1.5×1.5 m) and T9: Casuarina (1.5×1.5 m). The experiment was established in year July 2021 and data was collected in June 2022. The result indicate the maximum height was recorded in T2: Eucalyptus (1×1 m) 3.81 m followed by T5: Eucalyptus (1.2×1.2 m) 3.78 m, T8: Eucalyptus (1.5×1.5 m) 3.40 m which was at par with each other and minimum in T9: Casuarina (1.5×1.5 m) 2.42 m whereas the maximum girth was found in T4: Poplar (1.2×1.2 m) 6.91 cm followed by T2: Eucalyptus (1×1 m) 6.61 cm, T5: Eucalyptus (1.2×1.2 m) 6.16 cm, T1: Poplar (1×1 m) 5.91 cm which was at par with each other and minimum in T9: Casuarina (1.5×1.5 m) 3.22 cm after one year. Various linear function was attempted to predict biomass based on GBH (G) and Height (H). Prediction accuracy of Height, girth model was slightly better than the height and girth model. Linear model (Y=a + bH + cG), where Y denotes dependent variable (biomass) and H and G denotes independent variable (Height or Girth), performed better (than the remaining tested models) in terms of estimation precision and prediction accuracy. The AGB was maximum was found in T2: Eucalyptus (1×1m) 0.676 kg tree-1 followed by T5: Eucalyptus (1.2×1.2 m) 0.598 kg tree-1 and minimum in T9: Casuarina (1.5×1.5 m) 0.214 kg tree-1. After completion of one year Eucalyptus (1×1 m) showed best growth among all treatments.

“…In the past 60 years, a high-density plantation system that uses dwarf trees with close spacing has replaced the traditional production system that used standard trees with wide spacing (Robinson, 2011). Global trends demonstrate that a high-density plantation system's intensification in plantations leads to higher yield and production per unit area (Dhiman, 2018). A novel cultivation method called high-density planting allows for the accommodation of more plant's unit -1 area than is possible with traditional planting density (Goswami et al, 2014).…”

The study was carried out in area of Kandaghat and Solan blocks of Himachal Pradesh, India from November 2021 to April 2022 to study the constraints in high-density apple cultivation by the farmers of the mid-hills area of Himachal Pradesh, India. The present study fully relied on the primary data through a properly structured schedule for the production year 2021–2022, with a sample size of 60 farmers involved in high-density apple plantations. Garret’s ranking technique was used to find constraints perceived by the high-density apple cultivators. The objective of the research was to identify the prevailing problems of the high-density apple sector in the selected area. In this study the major problems faced by the high-density apple growers in production were the high cost of high-density apple plants, followed by identifying the disease, costly labor, and lack of technical guidance. Major marketing-related constraints expressed in the marketing of high-density apples were the problem of fluctuation of price, the high price of transportation, distant market, and high commission charges, further the data revealed that the major environmental and other related constraints were that the grading process and certification process seemed to be costly, problems from hailstorms were also found. The study also highlighted the need of proper marketing facilities as marketing helps in improving the living standard and eliminate the constraints in product and services.
