3.1 Introduction

Greenhouses are buildings with a controlled environment that facilitate plant culture and development. They offer protection from adverse external weather conditions, high temperatures, strong winds, and pests, while providing an ideal environment for plant growth. The construction of a greenhouse involves the use of various materials to ensure its structural stability, longevity, light transmission, and insulation. The different components of the greenhouse, such as the frame, flooring, and covering, are constructed using different materials such as wood, aluminum, steel, concrete, soil, gravel, and more.

2.1 Introduction

Greenhouses are used mainly for cultivating vegetables and fruits during the off-season to provide favorable growing conditions. Proper management of the greenhouse structure is necessary to create these off-seasonal favorable conditions for plants. Factors like site selection, location, atmospheric conditions, cropping pattern, and structure of the greenhouse are considered during the development of a greenhouse. The National Committee on the use of Plastics in Agriculture (NCPA-1982) suggests conducting site-specific greenhouse technology trials before implementation across the nation.

1.1 Introduction

The greenhouse industry is rapidly growing, particularly in mild climates, and is crucial for providing access to fresh and clean food. Greenhouses provide an optimal climate for crops to grow and protect them from outside pests. Furthermore, greenhouse production has the potential to reduce water waste and implement integrated protection and production (IPP). It is essential to consider the environmental impact of protected cultivation, and Life Cycle Assessment (LCA) is a valuable tool for evaluating these impacts.

1. Introduction

The Indian economy is heavily dependent on agriculture (employing 53 % population). Around 84 % of the holdings are less than 2 ha while approximately 67% of the farms have less than 1 ha of operational farmland (Government of India, 2013; Pandey and Suganthi, 2015). A large fraction of the farming population is mostly reliant on monsoon rains for irrigation. The condition of the farmers is found to be deteriorating year after year with the revelation that 27% of farmers did not consider farming as a profitable enterprise and 40% were ready to migrate to other avenues for employment (NSSO, 2005; Pandey and Suganthi, 2015). 

1. Introduction

The status of mechanization in India is at a very low level for horticultural crops. The farmers usually go behind the use of traditional methods for different farm operations (Fig 1) and practices for cultivation of horticultural crops, their handling, storage, and processing. This results in less yields, high cost of cultivation and high crop losses from harvesting till processing. The use of different available hand tools, machinery and hi-tech technologies in the production and processing of the crops will lead to increased yields and decrease in losses to a great extent (Mandhar, 1999).

Therapeutic plants have different metabolites in them because of which they are generally utilized in the whole world by individuals to fix different illnesses. India has a rich history of involving many plants for therapeutic purposes. Therapeutic plants are assuming an exceptionally dynamic part in conventional medications for the treatment of different afflictions. India is a rich wellspring of restorative plants because of the varieties in soil, their heights, and other ecological and geological conditions. India’s utilization of plants for medical services goes back nearly 5000 years, when Ayurveda systematized around 8000 natural cures by utilizing plants. Root and tuber crops possess a striking situation in the food security of the creating scene because of their high caloric worth and sugar content. Some of them are as of now under development; however different species are developing wild as a dismissed gathering of financial plants. A portion of the tuberous species is significant due to their restorative as well as modern application.
