Yield, Soil Health and Nutrient Utilization of Field Pea (Pisum sativum L.) as Affected by Phosphorus and Bio-fertilizers under Subtropical Conditions of Jammu

Abstract: A field study was conducted in Rabi season of year 2009-10 at the Agronomy Farm of SKUAST-J to evaluate the response of field pea (Pisum sativum cv. Rachna) to levels of phosphorus and bio-fertilizers under sun-tropical conditions of Jammu. Recommended dose of phosphorus recorded seed and stover yield of 15.85 q ha -1 and 33.63 q ha -1 , respectively higher than other phosphorus levels and control. Among seed inoculation treatments, dual inoculation of Rhizobium + PSB produced significantly higher seed and stover yield of 15.01 q ha -1 and 33.90 q ha -1 than inoculation with Rhizobium, PSB and control. The effect of recommended dose of phosphorus and dual inoculation on soil available NPK, NPK uptake in crop as well as protein content in seed was found significantly higher as compared to other treatments. Besides, the interaction effect of phosphorus and bio-fertilizers on soil available was found significant.

Agronomic Bio-fortification of Rice and Maize with Iron and Zinc: A Review

Abstract: Earlier, the agriculture system was oriented more towards achieving higher agronomic yields than the nutritional quality of food. Green revolution significantly enhanced the crop production primarily rice, wheat and maize production was boosted to meet the energy needs of growing population. As a consequence of the predominance of cereal-based staples that are fundamentally low in micronutrients, specifically Zn and Fe, more than 2 billion people worldwide suffer from an insidious type of deficiency known as micronutrient malnutrition. Just moderate amounts of micronutrient malnutrition can affect cognitive development, reduce disease resistance and increase the risk of women dying during childbirth. The approach to micronutrient fertilization has been shown to improve the yield and nutritional content of the staples. Agronomic biofortification provides an immediate and effective method to enhance accumulation of micronutrients especially Zn and Fe in cereals. An adequate amount of plant available micronutrients is a prime requisite to ensure adequate nutrient uptake. Most of the cereals are grown in soils deficit in Zn and under reduced conditions of rice ecosystem, its availability is decreased due to formation of less soluble Zn complexes with sulphate and carbonate. The form of fertilizer used, timing and method of Review Article Jan et al.; IRJPAC, 21(16): 28-37, 2020; Article no.IRJPAC.61049 29 application is critical for the enhancement of the grain quality of Zn and Fe. The effectiveness of agronomic biofortification can be enhanced by application of synthetic chelated micronutrient fertilizers and/or organic fertilizers fortified with micronutrients in combination with NPK ensuring proper nourishment of crops with adequate nutrient supply by slow release of nutrients in soil solution. Further, the response of foliar application has shown better results than soil application. Previous studies suggest that Zn fertilization not only enhances Zn concentration in grain but also improves the overall performance of maize crop. Agronomic biofortification of crops is advantageous in terms of accessibility, rapid result, ease in application and high sustainability.

Hydroponics – A Review

Abstract: Hydroponics can be briefly defined as cultivation of plants without soil (Savvas, 2017). In short, hydroponics, a Greek word meaning “hydro” (water) and “ponos” (labour) is the method of growing plants in different types of substrates (chemically inert), sand, gravel, or liquid (water), in which nutrients are added, but no soil is used (Savvas, 2003; Douglas, 1975) or hydroponics is a technique of growing plants in soil-less condition with their roots immersed in nutrient solution (Maharana and Koul, 2011). The word hydroponics was coined by Professor William Gericke in the early 1930s describe the growing of plants with their roots suspended in water containing mineral nutrients. Europe is considered the biggest market for hydroponics in which International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 8 (2020) Journal homepage: http://www.ijcmas.com

Rice-Wheat cropping system under changing climate Scenario: A review

Abstract: Climate change directly or indirectly influences all economics aspects, but agriculture is among the sectors which are most sensitive and inherently vulnerable to climate. The impacts of increased temperature from global warming and changes in rainfall patterns resulting from climate change are expected to reduce agricultural production and put further pressure on marginal land. Climate change and especially increase in ambient temperatures will reduce the yields of major cereal crops especially Rice-wheat. Hence, to achieve our goals of food security, we need to emphasize the use and production of food crops that can withstand the on-going changes to the climate, especially in the arid and semi-arid regions around the globe that are at a greater risk of food insecurity. There are key factors that significantly impact to mitigate stress conditions of the climate, i.e. short duration crop, value added weather services, genotype with higher per day yield potential, weather linked agricultural insurance etc.

Reactive Oxygen Species in Plants: From Source to Sink

Abstract: Reactive oxygen species (ROS, partial reduction or derivatives of free radicals) are highly reactive, dangerous and can cause oxidative cell death. In addition to their role as toxic by-products of aerobic metabolism, ROS play a role in the control and regulation of biological processes such as growth, the cell cycle, programmed cell death, hormone signaling, biotic and abiotic stress reactions and development. ROS always arise in plants as a by-product of several metabolic processes that are located in different cell compartments, or as a result of the inevitable escape of electrons to oxygen from the electron transport activities of chloroplasts, mitochondria and plasma membranes. These reactive species are formed in chloroplasts, mitochondria, plasma membranes, peroxisomes, apoplasts, the endoplasmic reticulum and cell walls. The action of many non-enzymatic and enzymatic antioxidants present in tissues is required for efficient scavenging of ROS generated during various environmental stressors. The current review provides an in-depth look at the fate of ROS in plants, a beneficial role in managing stress and other irregularities. The production sites are also explained with their negative effects. In addition, the biochemical properties and sources of ROS generation, capture systems, the influence of ROS on cell biochemistry and the crosstalk of ROS with other signaling molecules/pathways are discussed.

Hydroponics의 經濟性에 對하여

Abstract: The word hydroponics comes from two Greek words, \"hydro\" meaning water and \"ponics\" meaning labor. The concept of soilless gardening or hydroponics has been around for thousands of years. The hanging Gardens of Babylon and The Floating Gardens of China are two of the earliest examples of hydroponics. Scientist started experimenting with soil less gardening around 1950. Since then other countries, such as Holland, Germany, and Australia have used hydroponics for crop production with amazing results.

Nitrogen and Legumes: A Meta-analysis

Abstract: The current progress in agricultural production does not really cater to the demand of the burgeoning human population Consequently, this puts global food and nutritional security at a great risk This challenge calls for concerted efforts of all stakeholders to produce required quantity and quality of assured foods for ensuring food security In the past, the principal driving force was to increase the yield potential of food crops and to maximize productivity Today, the drive for productivity is increasingly combined with a desire for sustainability For farming systems to remain productive and to be sustainable in the long term, it will be necessary to replenish the reserves of nutrients which are removed or lost from the soil The nitrogen (N) inputs derived from atmospheric N via biological N fixation (BNF) Therefore, current farming systems need sustainable intensification through the inclusion of legume crops This facilitates the precise use of nitrogen (N) by reducing their losses into the environment and ensures self-sufficiency in protein The relevance of legumes in this context is enhanced as these crops offer numerous amenities that remain in line with prevalent sustainability principles Legume crops provide protein-rich food, oil and fibre while supplying the 195 Tg N year−1 (also includes actinorhizal species) to the agroecosystem through the process of biological nitrogen fixation (BNF) Besides serving as the fundamental global source of good-quality food and feed, legume crops contribute to 15% of the N in an intercropped cereal and mitigate the emission of greenhouse gases (GHGs) by reducing the application demand of synthetic nitrogenous fertilizers Legume cultivation releases up to seven times less GHGs per unit area than non-legume crops Legumes allow the sequestration of carbon (142 Mg C ha−1 year−1) in soils and induce the conservation of fossil energy inputs in the system The other benefits of legume crops include their significant positive impacts on biodiversity and soil health Rotating legume crops with non-legume crops has the dual advantage of cultivating the legumes with slight or no extra N fertilizer Care should be taken to ensure the availability of adequate N for the succeeding non-legume crops The legume crops respond very well to conservation of agricultural practices Overall, these characteristics are crucial to agriculture both in developing and developed countries apart from the conventional farming systems Legumes in rotation promote exploration of nutrients by crops from different soil layers They also help in reducing pressure on soil created by monocropping Thus, crop rotation acts like a biological pump to recycle the nutrients Hence, inclusion of legumes in the cropping system is inevitable to advance soil sustainability and food and nutritional security without compromising on the long-term soil fertility potential
