    Biological Nitrogen Fixation: An Analysis of Intoxicating Tribulations from Pesticides for Sustainable Legume Production
    (Springer Nature, 2022) Ahmad, Zahoor; Tariq, Rana Muhammad Sabir; Ramzan, Musarrat; Bukhari, Muhammad Adnan; Raza, Ali; Iqbal, Muhammad Aamir; Meena, Ram Swaroop
    A score of pedo-environmental factors serves as limiting elements for the biological nitrogen fixation (BNF) process in root nodules of leguminous plants. Since the advent of the green revolution, pesticides have been considered indispensable for keeping crop pests below the economic threshold level to ensure sustainable production of field crops for the rapidly increasing world population. However, pesticide application has also been associated with adverse effects on plant growth and development besides causing a detrimental reduction in microbial community dynamics. Rhizobium strains that are host-specific are no exception to this threat and are negatively influenced by different pesticides, especially fungicides, which seriously affect the functioning of the nitrogen (N) fixation process. Pesticides containing different synthetic chemicals affect symbiotic nitrogen fixation (SNF), and consequently, the amount of N fixed. This leads to reliance on crop plants primarily on N available in soil solution. Ultimately, reduced soil fertility leads to deteriorate crop productivity and quality of the produce. The objective of this review has been to synthesize, explore and critically analyze the effects of pesticide applications and their physiological impacts on BNF in legumes for sustainable crop production to strengthen food security for the increasing world population. Our review elucidates that indiscriminate use of agrochemicals could result in an undesirable environment for the healthy survival of symbiotic and symbiotic organisms leading to a corresponding reduction in exopolysaccharide (EPS) synthesis leading to poor atmospheric N fixation and thus affecting the whole agroecosystems. Therefore, by giving due consideration to the harmful effects of pesticides, farmers’ awareness about the safe usage of agrochemicals might be among the top priorities to conserve the environment besides harmonically preserving living organisms. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.

    Physiological Mechanisms of Plants Involved in Phosphorus Nutrition and Deficiency Management
    (CRC Press, 2022) Ahmad, Zahoor; Barutçula, Celaleddin; Waraich, Ejaz Ahmad; Ahmad, Adeel; Ayub, Muhammad Ashar; Tariq, Rana Muhammad Sabir; Iqbal, Muhammad Aamir
    Nutrients play an important role for the better growth and production of the field crops. In fulfilling the requirements of food along with the globe, through an improvement in crop productivity, balanced nutrition plays a vital role. Food crops require phosphorus (P) as a macronutrient for several functions like transfer of energy, cell division, and storage. Phosphorus improves forage, fiber, root growth, and grain yield. It not only strengthens stalk but also improves the early maturity of plants. In resistance against cold injury and root rot disease, P plays its role. Phosphorus is also crucial for cell differentiation and energy transactions. In the plant body, as a part of nucleic acids, phosphor-proteins, and phospholipids, P is a critical constituent of plant cells. The deficiency of P creates a negative impact on the morphology as well as the physiological process of the plants. Many researchers worked on the enhancement of crop productivity and assessed the role of P in plants. This chapter elaborated on three critical aspects of phosphorus; first is the P uses and role in crop plants while the second is the physiological mechanism of P in the plant. The third section discussed the management of P deficiency or toxicity in plants. © 2022 by Apple Academic Press, Inc.

    Pod shattering in canola reduced by mitigating drought stress through silicon application and molecular approaches-A review
    (Taylor & Francis Inc, 2022) Ahmad, Zahoor; Barutcular, Celaleddin; Rehman, Muhammad Zia Ur; Tariq, Rana Muhammad Sabir; Afzal, Muhammad; Waraich, Ejaz Ahmad; Ahmad, Adeel
    Climate change has become a serious threat all over the world, which creates a negative impact on the growth, physiology and yield attributes of the crops. Drought stress is one of the major causes of climate change that contributes more to the reduction of yield of crops and its physiological aspects (i.e., stomatal conductance, leaf temperature, plant canopy temperature, membrane thermal stability index, total chlorophyll content, chlorophyll fluorescence). Pod shattering negatively affects the yield of canola under drought stress conditions. The control of shattering, caused by drought, has been difficult due to the lack of resistant cultivars. Drought at any stage of canola, either vegetative or reproductive, badly affects the canola crops in terms of growth, physiology, pod development and its shattering, which results in the reduction of yield. To overcome the pod shattering and its development, the Si plays an important role, which provides the strength to the pod when it was applied with their proper amount and proper time. Si is the beneficial element which helps in improving the growth and physiology of crop under drought stress conditions. Si helps for reducing the pod shattering in canola and improving its yield by mitigating the adverse effect of drought on canola. Molecular approaches also help to provide resistance in canola against pod shattering and improve its yield under drought stress conditions. Current review highlights the role of Si and current molecular developments to deal with constraints in pod development and it's shattering under drought stress.
