“…The higher growth characteristics at higher fertigation levels may partially be assigned to the higher leaf nutrient content (NPK) in the tree foliage, which had a positive correlation with the level of fertilizer used (Treder 2006). The present findings are in confirmatory with the studies of Raina et al (2013), Kumar et al (2016) and Thakur et al (2020) who observed , maximum tree height and spread, annual shoot growth, trunk girth and tree volume with the application of 100 per cent AD (NPK) fertigation dose.…”

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).

“…Phosphorus fertigation via drip irrigation facilitates both horizontal and vertical movement of soil phosphorus near the outlet [43], and raises soil phosphorus concentration to a greater extent within the 0-30 cm soil layer rather than at the 30-60 cm layer in pear orchard [44]. Kumar et al [45] reported that available P was, in general, higher in surface 0-20 cm soil layers; however, it was markedly higher under drip fertigation compared to surface-irrigated apple orchards. Similarly, increasing doses of fertigation improved soil phosphorus and potassium availability have been reported for apricot [46].…”

In the current study, efforts were made to standardize fertigation for providing the recommended doses of fertilizers (RDF) i.e., 300, 260, and 200 g/plant/year for N, P, and K, respectively, together with optimization of irrigation scheduling so that guava plants could avoid the frequent episodes of nutritional stress, water scarcity, or overwatering. The experiment’s execution was confined to a three-factor randomized block design, with a total of 19 treatments that were replicated four times. Briefly, these treatments included drip irrigation and nutrient (NPK) application through fertigation dosages (RDF; 100, 80, and 60%) with and without silver-black plastic mulching. Different applied fertilizer dosages, together with different levels of irrigation and soil mulching, had a significant impact on the guava plant’s vegetative, reproductive, and nutritional aspects. Under silver-black plastic mulch, drip irrigation at cumulative pan evaporation (CPE) 80 and 100% of the prescribed dosage of fertilizers, better macronutrient availability in the soil, and improved plant development were recorded (M1DI2F1). Overall, using drip fertigation to provide NPK fertilizers close to the root zone increased the availability of nutrients to the plants as compared to the traditional fertigation and irrigation methods. Thus, this sustainable high-tech horticultural approach could be analyzed for its efficacy or applied to other crops to obtain adequate economic outcomes.

“…In a study conducted in 2018, Chen et al [26] found that when the annual N application rate in apple orchards was 200 kg•hm −2 , the photosynthetic capacity, fruit tree growth, and fruit quality were better than those obtained with an annual N application rate of 300 kg•hm −2 . Similarly, Kumar et al (2016) supplied fruit trees with 70 g of N each. Then, comparing different fertilization rates and fertilization methods, they found that 80% fertilization not only saved 40% of water and 20% of fertilizer by reducing fertilization and drip irrigation but additionally, improved productivity and ensured higher fruit quality in their sample [27].…”

Apple production provides smallholders with low economic benefits, while high environmental emissions limit the sustainability of the apple supply chain. Furthermore, coordination to achieve greater economic benefits and environmental protection, thereby improving the sustainability of the apple supply chain, remains underdeveloped. Here, we have analyzed the current status of the economic benefits and environmental emissions of the apple production process and explored the level of collaboration within the apple supply chain, based on an analysis of farmer horticultural practices for high production, high economic benefit, and low environmental emissions, in combination with substance flow analysis. Our study showed that compared with traditional practice, high-yielding, high-efficiency practice allowed fruit yield, partial productivity of nitrogen fertilizer, and economic benefit to increase by 33%, 61% and 49%, respectively, while soil nitrogen residue levels decreased by 13%. The improvement and adoption of technology in the apple-planting process significantly improved the sustainability of the apple supply chain: the economic benefit increased by 63%, while the nitrogen footprint decreased by approximately 68%. Additionally, the application of integrated nutrient management technology in the apple planting process significantly improved the sustainability of apple production, thereby synergistically improving the economic and environmental impact of the apple supply chain.
