The production of fruit crops is largely dependent on the environmental conditions and nutritional status of the plants. Any alteration in the environmental conditions and nutritional status may results in different physiological disorders which affect the growth of the plants and also the quantity as well as quality of the fruits. The precise and early recognition of physiological disorders is important for the timely adaptation of remedial strategies to reduce the crop loss. Physiological disorders in fruits crops may be due to single factors or multiple factors may be involved in the appearance of physiological disorders. A sound knowledge about the cause of physiological disorder is useful to adopt suitable remedy for the disorder.

Introduction

The abnormal growth behavior or unusual external and/or internal conditions of fruits which results due to adverse environmental conditions and nutritional imbalances are considered as physiological disorders. Physiological disorder is best defined as external or internal malfunctioning resulting from improper environmental or cultural conditions before and/or after harvest. Variation from normal temperature, light, moisture, nutrient, harmful gases, insufficient supply of growth regulators, deficiencies or excesses of nutrient etc. are some of the important environmental and cultural factors of physiological disorders (Fig. 1). Physiological disorders affect the quality as well as quantity of the fruit crops. Detection of precise physiological disorders is not easy and requires a strong knowledge regarding them.

Introduction

Fresh fruit journey from the farm to the consumer’s table is an intricate process which needs a lot of attention. The way that the produce is harvested and handled is of supreme importance in relation to its quality shelf life and general market attractiveness. Improper handling practices during these critical stages can bring both quantitative and qualitative loses hence the perishable produce will lose its commercial value and appeal to the consumers (Kader, 2005). No doubt the significance of successful harvesting and post-harvest handling practices is crucial and has an impact on quality features and safety in case of fresh fruits. Poor management can cause physical assault ripening speed and more susceptibility to the growth of micro-organisms which makes the produce unsuitable for consumption or processing.

Horticulture sector, comprising fruits, vegetables, floriculture, medicinal and aromatic crops, mushroom, spices and plantation crops, had witnessed phenomenal growth in production and productivity during the last two decades. Resultantly, horticulture in India is recognised as one of the fastest growing sectors in the world. The production has reached to 351.92 million tonnes in 2022-23 as compared to 231 million tonnnes in 2010. Progressive urbanization, increased spendable income and awareness for balanced and nutritious food have contributed towards increasing demand of horticulture produce. The increasing demand coupled with higher income returns per unit area has triggered this growth pattern, which has been largely possible due to policy environment to support horticulture both for research and development.

Fruits represent a vital component of global agriculture, serving as not only a significant source of essential nutrients but also a lucrative sector of the economy. However, from the moment of their inception on the tree to their arrival on consumers’ tables, fruits undergo a complex journey influenced by a myriad of factors. Among these, pre-harvest practices wield a profound impact on fruit quality, enzymatic activities, texture, ripening, and ultimately, post-harvest transportation losses. Each pre-harvest practice, from mineral nutrition to harvesting methods, plays a distinct role in shaping the biochemical composition and physical attributes of fruits, ultimately affecting their marketability and shelf life. Mineral nutrition stands as one of the foundational pillars of fruit production, with essential minerals serving as building blocks for various biochemical processes. Irrigation practices represent another critical aspect of pre-harvest management, as water availability profoundly impacts fruit development and composition. Different irrigation regimes can influence enzymatic activities, fruit texture, and the timing of ripening, necessitating strategic water management to achieve desired fruit quality while minimizing post-harvest losses. Canopy regulation, achieved through training and pruning techniques, offers growers a means to manipulate light penetration and airflow within the orchard. Moreover, the application of plant growth regulators (PGRs) emerges as a tool for fine-tuning fruit development and ripening processes. By modulating hormonal signals, PGRs can alter enzymatic activities, influence fruit texture, and mitigate transportation losses. However, judicious application is paramount to avoid adverse effects on fruit quality and safety. Harvesting decisions, including the determination of optimal maturity and the timing and method of harvest, profoundly impact fruit quality and post-harvest losses.

Horticulture crops contribute significantly for the total agricultural production and productivity. World production of fruits accounted for the total volume of 933 million tonnes (FAO, 2023). India being second largest producer for majority of fruit commodities had a production total reaching 108.34 million tonnes in 2022-2023 from an area of 7.15 million hectares. It accounts for 33 per cent to the agriculture GVA (Gross Value Added) and plays an important role in the Indian economy. India is second largest producer of majority of fruits and vegetables. Diverse agro-climatic zones in the country make it possible to grow almost all varieties of fruits in India. Produced fruits are used for domestic consumption, processing and export purposes. During 2022 23, fresh fruits exports was valued at 6219.46 crores (APEDA, 2023). The fruits grown in India includes domestic fruits and nuts along with the exotic fruits contributing for the food and nutritional security. The growth of these economically important fruits provides scope for maintaining rich germplasm, enhance bio-diversity and maintain ecological balance.

Introdction

Fruits are an important supplement to the human diet, as they provide minerals, vitamins and fiber required for maintaining good health. Fruits are also rich in phytochemicals (7, xanthophylls, polyphenols, flavonoids, phenolic acids, organic acids etc.) which possess good antioxidant properties. India’s diverse climatic conditions ensure availability of almost all the varieties of fresh fruits and vegetables. According to FAO (2021), the country ranks first in the production of bananas (26.45%), mangoes (including mangosteens and guavas) (43.80%) and papayas (39.30%). The scenario of horticulture crops in India has become very encouraging. The percentage share of horticulture output in agriculture has become 33 per cent (Anonymous 2021). India has witnessed increase in horticulture production over the last few years. Significant progress has been made in area expansion resulting in higher production. Over the last decade, the area under horticulture grew by 2.1 per cent per annum and annual production increased by 3.9 per cent. During 2020-21, the production of horticulture crops was 334.60 million tonnes from an area of 27.74 million hectares. The production of fruits has increased from 76.42 million tonnes in 2011-12 to 108.34 million tonnes in 2022-23 (Agricultural Statistics at a Glance 2022). The area under cultivation of fruits stood at 7.05 million hectares. The total production of fruits in the year 2020-21 was highest in case of Andhra Pradesh (17.70 million tonnes) followed by Maharashtra (11.73 million tonnes) and Uttar Pradesh (11.23 million tonnes) (Anonymous 2021). India now is the second largest producer of vegetables and fruits in the world. The country ranks at first position in the production of banana, mango, lime and lemon, papaya and okra. The area and production of fruits in India is presented in Table 1. The fruits namely banana, mango, citrus, papaya, guava, grapes, apple, pineapple and sapota account for more than 85 per cent of the total production of fruits. The other fruits which are produced in India are almond, walnut, jackfruit, bael, ber, custard apple, kiwi, passion fruit, peach, pear, plum, strawberry etc.

The contribution of dairy sector in the Indian economy has tremendous impact on the country’s GDP. India being the world’s highest milk producing country, dairy industry has a major role in changing the twin problem of the nation that is poverty and unemployment. Dairy sector also involves the under privileged group, especially the dairy farm women. There are many success stories regarding the life changing experiences gained by the farm women, who had taken dairy farming as a means to sustain their livelihood. In the area of gender equality, dairy sector has proved to be a women centric enterprise. Most of the activities pertaining to dairy farming are mostly carried out by the farm women. The dairy farming activities carried out by the farm women are tedious and in major cases their contribution remains unnoticed. They are usually carrying out activities, where most of their energy is drained, resulting in drudgery. Matters related to decision making, their opinion about adopting new technologies, starting an enterprise are not given importance by their family members. This leads to a greater setback in the emergence of success of dairy sector. Therefore, empowerment of farm women in dairy sector is one of the important criteria for the dairy industry to reach a greater height and for overall development of nation.
