The field experiment was conducted at Horticulture farm, Rajasthan Agricultural Research Institute, Durgapura (Jaipur-Rajasthan) during 2019-20 and 2020-21. The experiment comprised of 12 treatment combinations consisting of 3 drip irrigation levels (50%, 75% and 100% at PE level) and 4 fertigation levels (100%, 75%, 50% of recommended dose of fertilizers through drip and 100% of RDF as basal dose). The experiment was laid out in factorial Randomized Block design. The experimental results revealed that among different treatment combinations highest fruit quality characters such as TSS (B0), TSS:Acid, reducing sugar (%), total sugar (%) and lowest value for acidity (%) and non-reducing sugar (%) of pomegranate fruit was found under treatment I2F3 (75% irrigation at PE level + 75 % RDF through drip).

“…It is also clear from the pooled data for two consecutive years that fruit lengths and diameters improved by 10.67% and 8.66%, respectively, and were improved under DI75 as compared with DI50 conditions. The increased fruit lengths and diameters under moderate water deficit conditions might be due to balanced vegetative growth and maximum interception of light, as elucidated by Kumawat et al (2017) for guava. Similar findings for guava were also reported by Kaushik et al (2013) and Preet et al (2021).…”

Drip irrigation and mulching are often used to alleviate the problem of poor water management in many crops; however, these technologies have not yet been tested for applying water at critical stages of guava orchard growth in subtropical humid Tarai regions of India to improve the yield and quality. A field experiment was conducted over 2020 and 2021 which included three irrigation strategies: severe deficit irrigation (DI50), moderate deficit irrigation (DI75), and full irrigation (FI100), as well as four mulching methods: silver-black mulch (MSB), black mulch (MB), organic mulch (MOM), and a control without mulch (MWM). The results showed that both the relative leaf water content (RLWC) and the proline content exhibited an increasing trend with a decrease in the irrigation regime, resulting in a 123% increase in the proline content under DI50 conditions compared with FI100, while greater plant growth was recorded in fully irrigated plants and using silver-black mulch. Leaf nutrient analysis showed that FI100 and MOM produced significantly higher concentrations of all nutrients. However, moderate deficit irrigation (DI75) along with silver-black mulch (MSB) produced higher numbers of fruits per plant, higher average fruit weights, higher fruit yields, and maximum ascorbic acid contents. The irrigation water productivity (IWP) decreased with an increase in the irrigation regime; from severe water deficit to full irrigation, resulting in a 33.79% improvement in IWP under DI50 conditions as compared with FI100. Regression analysis outperforms principal component regression analysis for fruit yield prediction, with adjusted R2 = 89.80%, RMSE = 1.91, MAE = 1.52, and MAPE = 3.83. The most important traits affecting the fruit yield of guava, based on stepwise regression, were leaf proline, leaf Cu, fruit weight, and IWP.

“…of guava plant growth response due to rhizospheric microclimate alteration. The increment in growth activity is also regulated by the amount and duration of bioavailable nutrients in the soil solution by optimizing photosynthesis and its partitioning; thus, a significant increment in canopy volume may have been the result of fertigation scheduling at 80% CPE [29]. Drip irrigation maintains a consistent moisture regime in the soil and roots remain active throughout the season, resulting in optimum availability of nutrients and proper translocation of food materials, which accelerate the fruit growth and development in guava.…”

“…Drip irrigation maintains a consistent moisture regime in the soil and roots remain active throughout the season, resulting in optimum availability of nutrients and proper translocation of food materials, which accelerate the fruit growth and development in guava. An increase in the vegetative growth with increasing fertigation levels might be attributed to better supplementation and utilization of nutrients and moisture, particularly in the plants with the highest dose of NPK when applied through fertigation, which in turn enhances cell division and formation of more tissues, results in more vegetative growth, and leads to higher annual extension and plant spread increase in leaf area [29]. A direct relationship between nitrogen application and vegetative growth is a well-established fact in guava [27].…”

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.
