Optimizing the Determinants of Water Use Efficiency in Mango

Abstract

Water use efficiency (WUE) is a dependent factor in orchard ecosystems. Enhancing WUE in any agroecosystem is the national priority for achieving the goal of more fruit per drop of applied water. Farmers' practice of full irrigation in the basin by flooding reduces the scope of better WUE. Innovative approaches like deficit irrigation certainly improve WUE in mango, across climates. Statistical analysis and histographic diagrams showed maximum frequency distribution of pan evaporation of 103% in class intervals of 3.14 to 5.97 mm day -1 followed by 0.3 to 3.13 mm day -1 (99%) under subtropical conditions. The histographic distribution of reference evapotranspiration (ET0) indicated the highest frequency distribution of 96% in 4.98 to 6.32 mm day-1 and 83% in 0.93 to 2.27 mm day-1. Statistical histographic distribution of mango (cv. Dashehari) yield under subtropical climatic conditions indicated 85.4 to 108.04 kg fruits tree -1 at a 9% frequency level. The highest WUE of 20.43 to 23.96 kg fruits m -3 of water applied was obtained under a 6% frequency distribution. The deficit irrigation strategy was found to be the most appropriate for optimum yields of mango under subtropical conditions.

Genetic Engineering in Indian Mustard (Brassica juncea L.): Current Progress and Future Directions for Enhanced Crop Improvement

“…Hybridization, leveraging the phenomenon of heterosis, has emerged as a powerful strategy to enhance productivity in numerous crop species. Brassica juncea, commonly known as oilseed mustard and a staple oilseed crop in the Indian subcontinent, exhibits distinct gene pools, particularly Indian and east European varieties [42]. Addressing this challenge, we present the development of DMH-1, a hybrid mustard variety, facilitated by a novel Cytoplasmic Male Sterility (CMS)-restorer system conducive to large-scale hybrid seed production [43].…”

“…Further characterization revealed that '126-1' CMS did not induce aberrations in floral or vegetative features, maintaining normal flower development, nectar production, and female fertility [42]. The development of DMH-1, utilizing the '126-1' CMS, involved crossing the Indian cultivar Pusa bold with the east European line EH-2.…”

A Comprehensive Review on the Impact of Climate Change on Fruit Yield and Quality in Modern Horticultural Practices

“…Comparative analyses of historical and current quality data for fruits in India reveal significant changes over time. For instance, long-term studies on mangoes in Uttar Pradesh show shifts in quality parameters like flavour and texture, corresponding with regional climatic changes over the past few decades [30].…”

Estimating heat use efficiency in mango under subtropical climate

“…The energy-matter interaction occurring within an agroecosystem needs to be quantified to have an understanding of climatic responses to the existing production ecosystem. Adak et al (2022) quantified the water use efficiency under subtropical climates to optimize water practices in mango. Knowledge of weather indicators, their dynamics, and their effects on tree functions is of great value for evaluating treeclimate interaction at a particular zonal area.…”
