Nutritional Benefits

Water stress has become the most uncontrolled and unpredictable factor, which is continuously limiting production in crops. Legumes are the major source of protein and are well-recognized for their nutritional benefits as well as their impact on the sustainability of agricultural systems are well known. Leguminous crops are severely affected by water stress causing alterations in various development processes. Proper nutrient management helps in attaining economical legume yields from drought-prone lands. The protective role of potassium in plants suffering from water stress has been documented and it positively influences plant capacity to adjust water stress conditions. This review compromises the information on the water stress-induced harmful effects on legumes growth, nitrogen fixation, gaseous exchange and mineral uptake parameters and proposes appropriate management by potassium application to alleviate the severity of water stres on above mentioned parameters. Application of potassium proved to meet higher yield from legume on cultivation under low/residual soil moisture availability conditions.

Background: Water stress is a global issue to ensure survival of agricultural crops. Mungbean has a great nutritional value, short-duration and has an advantage that it can grow in wide range of soils and environments. For the present study, two varieties of mungbean were selected and raised in earthen pots. Methods: Water stress was imposed at 50% flowering (35-40 days after sowing) and plants were sampled at this stage. The control plants maintained at soil moisture content (SMC) of 12.0 ± 0.5% and in stressed plants, water stress was created by withholding irrigation till SMC decreased to 4.5±0.5%. In legumes, damaging effects of drought can be reduced by potassium supply. Potassium was supplied to the soil at concentration 0.00, 1.54 mM, 2.31 mM, 3.08 mM. Result: This article includes water stress-induced harmful effects on mungbean growth and development, nitrogen fixation and biochemical traits and suggests that different concentrations of potassium fertilizer help to reduce the negative effect of water stress.

Pulses cover a vast area of the Bundelkhand (UP) and Mungbean is prominent among the pulse crops and it is grown on a larger scale using local varieties entirely in dryland conditions and on residual soil moisture and fertility. In Bundelkhand, farmers grow the crops traditionally and without considering the scientific recommendations. Inorganic fertilizers (synthetic) are an important source of plant nutrients but their continuous and injudicious use posing health and environmental complications. Minimum use of inorganic sources of nutrients and rely on integrated nutrient management is the way to tackle the health and environmental issues due to imbalance and excessive use of inorganic nutrients. Phosphorus, PSB and vermicompost are found to play very important role in boosting the yield of legume crops. This research is, therefore, taken into account to evaluate the response of Mungbean crop to phosphorus, PSB, and vermicompost. The leguminous crops require more phosphorus as it is required for energy transformation in nodules. Phosphate solubilizing bacteria (PSB) is assumed to have greater significance because it helps to convert insoluble organic phosphates into simple and soluble forms. Vermicompost is a better and rich source of N, P, K, and micronutrients. Besides, containing a good proportion of exchangeable Ca, Mg, Na, etc., vermicompost enhances organic carbon to the soil and meagerly helps to release of nutrients and in turn uptake is improved. A field experiment was performed during Kharif season, 2019 at Agriculture Farm of Banda University of Agriculture and Technology Banda, Uttar Pradesh, India. Results of the study reveals that the basal applications of 75 kg DAP, 5 t Vermicompost (VC) ha-1 and seed treated by Phosphate Solubilizing Bacteria (PSB) led to a significant increase in yield attributing characters and yield and gave by 22.57% more yield advantage than the farmer’s practice. However, the application of higher doses of DAP with VC and PSB gave luxuriant growth to the crop rather than increased yield.

Indian livestock sector is one of the largest in the world and fodder is vital component of profitable animal production. Legumes are one of the predominant crops of mixed crop-livestock systems providing highly nutritious fodder as well as contributing soil fertility. Nevertheless, the fodder production and quality in the country is not adequate to meet out the prerequisite of growing livestock population. Optimum nutrition is thus required for getting the maximum forage yield and quality. Nutrient Management is propounded as a promising strategy for addressing such challenges. Microbial inoculants being an important component of integrated nutrient management are eco-friendly and economical sources of nutrient. The benefit of combining organic and inorganic sources of nutrients in integrated nutrient management has proved superior to the use of each component individually. Thus, the present review will feature the need of integrated nutrient management, plant growth promoting rhizobacteria as microbial inoculants, role of microbial inoculants in integrated nutrient management of various leguminous crops and emerging examples of integrated nutrient management in cowpea. The realization attained from literature assessed herein will further help to understand the role of microbial inoculants in integrated nutrient management.

Respiration in the light, dark respiration, and leaf water status were monitored once a day in leaves of woody plants as seedlings dried during 7- to 10-day periods. Light respiration was estimated from an electrical analogue model of the response of net photosynthesis to ambient CO2 concentration and also by the rate of CO2 evolution into CO2-free air. Respiration in the light was found to increase with water stress in four dry-habitat species and to decrease with stress in four wet-habitat species. Dark respiration changes could not account for the different trends observed. When light respiration in dry-habitat plants under water stress was temporarily inhibited, net photosynthesis during recovery from water stress was reduced compared with controls for at least a week. This may indicate a protective role of light respiration in these plants when under water stress.

Abstract Recently, we have read with great interest the article published by Ibarrola et al. (Clin. Sci. (Lond.) (2018) 132, 1471–1485), which used proteomics and immunodetection methods to show that Galectin-3 (Gal-3) down-regulated the antioxidant peroxiredoxin-4 (Prx-4) in cardiac fibroblasts. Authors concluded that ‘antioxidant activity of Prx-4 had been identified as a protein down-regulated by Gal-3. Moreover, Gal-3 induced a decrease in total antioxidant capacity which resulted in a consequent increase in peroxide levels and oxidative stress markers in cardiac fibroblasts.’ We would like to point out some results stated in the article that need further investigation and more detailed discussion to clarify certain factors involved in the protective role of Prx-4 in heart failure.

The Relationship

Parenting behaviors – specifically behaviors characterized by high control, intrusiveness, rejection, and overprotection – and effortful control have each been implicated in the development of anxiety pathology. However, little research has examined the protective role of effortful control in the relation between parenting and anxiety symptoms, specifically among adults. Thus, we sought to explore the unique and interactive effects of parenting and effortful control on anxiety among adults (N = 162). Results suggest that effortful control uniquely contributes to anxiety symptoms above and beyond that of any parenting behavior. Furthermore, effortful control acted as a moderator of the relationship between parental overprotection and anxiety, such that overprotection is associated with anxiety only in individuals with lower levels of effortful control. Implications for potential prevention and intervention efforts which specifically target effortful control are discussed. These findings underscore the importance of considering individual differences in self-regulatory abilities when examining associations between putative early-life risk factors, such as parenting, and anxiety symptoms.
