Therefore, there is an urgent need to achieve better nutrient dynamics and sustainable production by selecting more nutrient-responsive cultivars using efficient nutrient management. The present experiment aimed to enhance crop productivity, seed quality, nutrient efficiency, and soil nutrient dynamics through efficient nutrient management under different lentil cultivars. The experiment was laid out in a split-plot design, assigning three cultivars (viz. Sapna, Garima, and HM-1) in the main plots and ten nutrient management practices in the sub-plots, replicating them thrice. Results revealed that cultivar HM-1 recorded significantly higher seed yield (1.59–1.61 Mg ha-1) and the uptake of N (67.2–67.6 kg ha-1), P (6.8–7.0 kg ha-1), K (13.8–13.9 kg ha-1), Zn (60.4–61.1 g ha-1), and Fe (162.5–165.2 g ha-1) in seed compared to Sapna and Garima.

The global pulse area, production, and average productivity increased from 1961 to 2020 (60 years). Pulses are usually grown under rainfed, highly unstable, and complex production environments, with substantial variability in soil and environmental factors, high year-to-year output variability, and variation in soil moisture. Since the last six decades, there is not much satisfactory improvement in the yield of pulses because of their cultivation in harsh environments, coupled with their continuous ignorance of the farmers and governments in policy planning. As a result, the global food supplies through pulses remained negligible and amounted to merely ~1.0% of the total food supply and 1.2% of the vegan food system. In this situation, protein-rich food is still a question raised at the global leve...

As an exhaustive crop, sugarcane removes a huge amount of plant nutrients from the soil. However, the combined use of organic and inorganic fertilizers can be a good approach to deal with nutrient depletion and promote sustainable crop production as well as improve soil health. Therefore, an attempt was made to identify the most fruitful and profitable integrated nutrient management on the aspects of growth, yield and quality of sugarcane in two consecutive growing seasons.

Thus, biofortification of staple food crops enriched with micronutrients is a more sustainable option for providing nutritional supplements and managing malnutrition in a society. Since 2001, when the concept of biofortification came to light, different research activities have been carried out, like the development of target populations, breeding or genetic engineering, and the release of biofortified cultivars, in addition to conducting nutritional efficacy trials and delivery plan development. Although, being a cost-effective intervention, it still faces many challenges, like easy accessibility of biofortified cultivars, stakeholders’ acceptance, and the availability of biofortified germplasm in the public domain, which varies from region to region. Hence, this review is focused on...

This study applied a participatory assessment method to assess farmers' preferences and willingness-to-pay for selected CSA practices and technologies in diverse rainfall zones. New climate risks require changes in agricultural technologies and approaches to improve the lives of those still locked in food insecurity and pov...

The AM (Arbuscular Mycorrhizae) fungi expand their filaments in soil and plant roots. These filamentous networks promote bi-directional nutrient movement where soil nutrients and water move to the plant and plant photosynthesis flow to the fungal network. AM fungi are ubiquitous in the soil and can form symbiosis with most terrestrial plants including major crops, cereals, vegetables and horticultural plants. Soil microbial populations are immersed in a framework of interactions known to affect the soil quality. AM fungi induced changes in plant physiology; affect the microbial populations both qualitatively and quantitatively, in rhizosphere or mycorhizosphere. Therefore, the rhizosphere of a mycorrhizal plant has different features than those of a non-mycorrhizal plant. AMF involved in fundamental activities that enhanced th...

Even after a good nutritional status in soil, it does not give its potential in crop production due to certain reasons indicating the prevalence of soil sickness. It reduces the amount of yield along with its quality of many agronomic and vegetable crops. The reasons behind the soil sickness could be autotoxicity due to release of allelochemicals by plant species, continuous monocropping, use of agrochemicals and others. These all factors destroy the proper balance of soil nutrients including micronutrients, composition and activities of soil microorganisms, disruption in rhizosphere soil homeostasis, soil physicochemical properties, and infestation of insect-pest and diseases specifically soil borne diseases. Therefore, it’s very imperative to intensify the farming system more sustainably by diversifying crops’ cultivation, preventin...

Waterlogging is a condition of soil in which excess of water limits gas diffusion. It subjects plants to the stresses of low light, limits gas diffusion, effusion of soil nutrients, mechanical damage, emission of green houses gaseous and increased susceptibility to pest and diseases. Thus growth and development of most plants except for rice and other wetland species are hindered under waterlogged conditions. Rice unlike other cereal crops can grow well in submerged fields and highly tolerant of excess water stress, from submergence. Water logging is excess water in the root zone accompanied by anaerobic conditions. Surface water logging affects daily life activities such as agriculture, transport, construction etc. Due to reduced bearing capacity, agricultural machinery cannot operate well in the fields. Water logging causes destruction of roads and structures due to reduced bearing capacity of waterlogged soil and uplift pressure.

The phenotypic and genotypic coefficient of variation (PCV and GCV) was high for days to 50% tasseling followed by kernel rows per year and 100 grains weight, respectively. Higher values of broad sense heritability were obtained for almost all the characters except days to 50% tasseling which is moderate. High heritability coupled with high genetic advance as per cent of mean was reported for plant height, grain yield per plant and ear height. However, correlation studies showed that grain yield per plant had significant phenotypic correlation with ear length, whereas, high positive direct effect on grain yield per plant was found to be highest for days to maturity followed by kernel rows per ear, grains per ear revealing that these are the major yield contributing traits in maize.

The prolonged intensive and indiscriminate use of agrochemicals adversely affected the soil biodiversity, agricultural sustainability, and food safety, bringing in long-term harmful effects on nutritional security, human and animal health. Most of the agrochemicals negatively affect soil microbial functions and biochemical processes. The alteration in diversity and composition of the beneficial microbial community can be unfavorable to plant growth and development either by reducing nutrient availability or by increasing disease incidence. Currently, there is a need for qualitative, innovative, and demand-driven research in soil science, especially in developing countries for facilitating of high-quality eco-friendly research by creating a conducive and trustworthy work atmosphere, thereby rewarding productivity and merits. Hence, we reviewed (1) the impact...
