Malnutrition problem is one of the biggest threats that India has been combating since its independence. Further, as farmers worldwide experience more frequent drought and erratic rainfall linked to climate change, the race to find and improve drought-resistant crops grows ever more important. Alternate crops must be incorporated into our normal diet, dispelling the idea that they are only grown by the poorest of the poor. Nutrient dense crops like millets, quinoa, chia, grain amaranth etc. are being increasingly recognized for their potential to play important roles as alternative food grains. Stress-resistant crops are needed to ensure yield stability under stress conditions and to minimize the environmental impacts of crop production. The introduction of new cultivated species and improved varieties of crops is a technology aimed at enhancing plant productivity, quality, health and nutritional value and/or building crop resilience to diseases, pest organisms and environmental stresses. It reduces the risk of total crop failure and also provides alternative means of generating income, as different crops will respond to climate scenarios in different ways.

Gokshura (Tribulus terrestris L.) is very valued herb in the Indian Ayurvedic system of medicine for treatment of various kinds of diseases. Plant contains various chemical viz., Gitogenin, Astragalin, Dioscin, Gracillin, Hecogenin, Ruscogenin, Trillin, Spirosterol, Saponin etc. which are found medicinally important. Various studies which are done on Gokshura revealed the result that the plant possesses Antiurolithiatic, Antimicrobial, Antihelminthic, Cardiotonic, Anti- inflammatory, Hypolipidemic, Immunomodulatory, Antispasmodic, Analgesic, Aphrodisiac, Antidiabetic, Anti-tumour, Hepato-protective, Anticarious, Anti-oxidant, CNS modulator properties. Considering its therapeutic values, this article has been done to gather complete information on different aspects of Gokshura.

In India, lakes, rivers and other freshwaters support a large diversity of biota representing almost all taxonomic groups. From an ecological point of view, the diversity of species present in the wetlands is an indication of the relative importance of the aquatic biodiversity issue as a whole. The total numbers of aquatic plant species exceed 1200 and aquatic vegetation is a valuable source of food. In the winter, migratory waterfowl search the sediment for nutritious seeds, roots and tubers. Resident waterfowl may feed on different species of aquatic vegetation year-round. Aquatic vegetables are "environmentally friendly": they suffer from few diseases and pests and can be grown without chemical fertilizers. Concerted efforts are being made to unravel the genes that lie behind some of these attractive traits, such as resistance to pests.

Dry flower industry is contributing about 70 % share of flower export from India. The technique of drying of flowers is not new and has been practiced over the centuries. Dried flower arrangements remain as it is, look beautiful and add colour to a home and do not wilt and require replacement unlike fresh flowers. Different flower parts are generally utilized for making dry flowers viz

By integrating water, nutrient, and energy, multi-enterprise farming increases productivity and profitability in small farms. By recycling byproducts and residuals from different components within the system, it has the potential to reduce cultivation costs for farmers and ensure a stable source of income and employment.

Reproduction is one of the important phenomenon in insects for their successful establishment and predominance in the Universe. It is not only involved by joining of male and female insects together and oviposition rather involves many pre copulatory behaviors which significantly influence the rate of success in reproduction. In most cases, male insects are attracted towards females by sensing through a specific cues includes pheromones, visual activities, acoustics etc. In order to ensure the copulation and reproductive success, a specialized behavior, Nuptial Gifting is noticed in many insects. It encompasses transfer of any form of nutrients from the male to the female during or directly after copulation. This transfer of gifts can be performed in three ways viz., oral gifting, seminal transfer and transdermal injection. This behavior secure the paternal investment through increase the life fitness, offspring population of the gift offering male insects and entice females for copulation and ensures maximum sperm transfer. Thereby, nuptial gifts evolved as ban to balance reproductive costs between the sexes.

Nematodes are cylindrical, multicellular, microscopic, sessile organisms that are ubiquitous in nature and possess characteristics of ideal bio-indicators. Of the estimated 5,00,000 species only 1 percent is identified and the rest are yet to be explored. Only a handful of nematode species are detrimental to plants and animals while rest attributes to many beneficial environmental impacts seen and unseen. Free living nematode C. elegans contributed significantly to research of organ development and programmed cell death. Nematode species Odontophora villoti, Parasphaerolaimus paradoxus, Trichotheristus mirabilis, Theristus pertenuis etc. act as biological indicators to disturbances like ecological disturbances like heavy metals, hydrocarbon pollution, organic enrichment, xenobiotics, and combinations. The nematodes are known to impact the process of nutrient cycling while maintaining the soil health by breaking down the organic matter in the food web. Predacious nematodes in soil parasitizes various pathogens and pests that are detrimental to the crops. In the hue and cry of sustainability entomopathogenic nematodes are promisingly widely used as biological insecticides in sustainable pest management programs. So nematodes are a major bane to the society and its full potential to synergize mankind is to be explored.

Cashew has concurred the highest status in global market because of its countable nutritive status. The productive performance of cashew is greatly influenced by how best its canopy is manipulated for harnessing maximum benefits in terms of yield. Pruning of dead wood and crisscross branches can alone increase the yield by 30-40 per cent. The dwarf rootstocks also play a role in manipulating the canopy in cashew, wherein, canopy containment and yield were influenced by rootstocks. The canopy manipulation increases cashew productivity two-to three-fold and considered as superlative solution for food security.

Natural farming follows the application of traditional knowledge which is chemical free for sustainability of agriculture. It is also known as Bharatiya Prakritik Krishi Paddhati Programme (BPKP). Mostly, compost, vermi-compost, cow dung manure, etc. are used here as organic fertilizer and manures. The natural farming has better impact on soil, air, water, etc. which ensures safe environment and safe food. By realizing the importance of natural and organic farming, ICAR-CIWA, Bhubaneswar had sensitized the selected farm women in Puri district of Odisha about utilization of farm bi-products, use of green manure and vermi-compost, etc. For the reason, enhanced the capacity of farm women in production of vermi-compost to use in farm lands, cultivation of mushroom by using paddy straw (paddy bi-product) for family nutrition and economic security and also growing azolla in indigenous earthen pots to feed backyard poultry for reducing feed cost. Nevertheless, the challenges are many in natural farming. However, it's need is badly felt by the researchers for healthy maintenance of farm lands as well as environment.

Drones are a good contender for enhancing agricultural techniques at a low cost. Aside from the financial benefits, optimizing fertilizer, pesticide, and water usage in important areas has various ecological and environmental benefits that would not be feasible otherwise. Drones, for starters, are great for monitoring and sensing techniques because they can quickly cover territory to check crop development and soil health. Drones are mostly used for this purpose since their sensors can detect the absorbance of a specific wave length, resulting in a color contrast image that visibly reflects possibly problematic locations.
