Wheat, one of the most important staple food crops in the world, is adversely affected by drought. With a view to understand the traits, which can be used as a quick criteria for early prediction of drought response, field and laboratory experiments were conducted to evaluate eight wheat (Triticum aestivum L.) genotypes. Moisture stress in laborato...

Moisture stress is one of the most important factors limiting the survival and growth of plants in semi arid tropics. Osmotic adjustment is an important adaptive response to moisture stress in wheat (Triticum aestivum L.). The objective of this study was to determine the relationships between osmolyte accumulation, activity of enzymes involved in o...

Conventional agriculture can result in loss of organic matter (OM), resulting in degradation of cultivated soil. A study was conducted to assess the impact of different tillage treatments in rice and wheat cropping system on soil organic carbon and nitrogen pool.

The future of agriculture is questionable under the current climate change scenario. Climate change and climate- related calamities directly influence biotic and abiotic factors that control agroecosystems, endangering the safety of the world’s food supply. The intricate interactions between soil microorganisms, including plants, bacteria, and fung...

Sustainable food security and safety are major concerns on a global scale, especially in developed nations. Adverse agroclimatic conditions affect the largest agricultural-producing areas, which reduces the production of crops. Achieving sustainable food safety is challenging because of several factors, such as soil flooding/waterlogging, ultraviol...

Wheat is the major staple food crop of India as well as of world. There is a need to enhance the production to feed the growing population in near future. There are many factors responsible for reduction in yield and weed infestation is one of the principle reasons among them. Weeds compete with the crops for various essential resources and do not...

Soil microbes are microscopic organisms that inhabit the soil and play a significant role in various ecological processes. They are essential for nutrient cycling, carbon sequestration, and maintaining soil health. Importantly, soil microbes have the potential to sequester carbon dioxide (CO2) from the atmosphere through processes like carbon fixa...

Plants are a highly advanced kingdom of living organisms on the earth. They survive under all climatic and weather variabilities, including low and high temperature, rainfall, radiation , less nutrients, and high salinity. Even though they are adapted to various environmental factors, which are variable, the performance of a crop will be compensate...

Mycorrhizal fungi have a unique symbiotic relationship with citrus plants that is essential for citrus growth. For establishing symbiosis between plants and fungus, it is important for the plant to supply the energy to the fungus for their growth and maintenance via photosynthetic products, while in return the fungus provides nutrients and water to...

Climate change has been considered among the greatest challenge to living organisms. Medicinal and aromatic plants are no exception to it. The practice of use of therapeutic plant has proved to be particularly important in the health system all over the world. WHO predicted that 60% of the earth population and 80% of the population of 3rd world cou...

Climate change is presently the greatest threat for biodiversity, species relocation, and distribution and metabolism of most of the organisms. Plants and their interacting flora and fauna are also highly affected with this climate change, which is the main cause of biotic stress for plants. Plants in their surrounding environment often come across...

Rice–wheat cropping system (RWCS) is considered as the furthermost vital system in the Indo-Gangetic Plains of South-Asia, including India, Pakistan, Bangladesh, and Nepal. Recently, the deficiency of micronutrients like zinc (Zn) has emerged as one of the prime limitations for the sustainability issues of this RWCS in Zn deficient calcareous soils...

A study was conducted in an ongoing experiment under AICRP on micronutrients at nursery jhilli of RPCAU, research farm. The experiment consisted of thirteen treatments, of which twelve combinations were of four doses of zinc (Zn) (2.5, 5.0, 7.5 and 10 kg ha-1), three frequencies (only once, alternate year and every year) of application along with c...

Water scarcity is a great constraint to plant productivity. The losses of yield due to drought supersede all the other losses since both the severity and duration of the stress are critical. Reduction in leaf size, stem extension and root proliferation takes place due to drought stress, which collectively hampers plant water relations and reduces w...

Rice is a staple food of more than half of the world’s population; more than 3.5 billion inhabitants depend on rice for obtaining 20% of their daily calorie intake. Nitrogen is the most important for crop growth and yield potential. Indeed, nitrogen is essential to stimulate tillering, leaf growth, photosynthesis, and protein synthesis. Significant...

The present investigation has been carried out to study the effect of various concentrations of salicylic acid (SA) on the germination performance of wheat (cv. C 306 and HI 1544) seeds, which are most prominently grown varieties in Vidisha district of Madhya Pradesh. The seeds of these varieties were exposed to different concentrations of salic...

Today’s life is highly energy dependent. Is it possible to meet our energy demand in the future by rapidly depleting energy resources? The answer is no. The alarming hike in crude oil and its final products prices evidently shows the terrible future conditions.
