Agriculture is the backbone of the economic system of the country. Most countries have an economy that depends on agriculture—either in a small or a big way. From employment generation to contribute to National Income, agriculture is important. The green revolution was pivotal for the progress of agriculture in India and helped us attain self-susta...

The relative presence of pollutants such as suspended particulate matter (PM2.5 and PM10); gases such as NO2, SO2, CO2, CO, and CH4; volatile organic compounds; polyaromatic hydrocarbon; and heavy metals (Ni, Cd, As, Pb, etc.) determines the quality of air, which is not only a critical determinant of human health but also a key regulator of plant g...

Radionuclides have now become part and parcel of our lives, and there does not seem any escape from them. Radionuclides have shown immense application potential in various fields of science and medicine, and thus, their management acquires utmost priority. Radioisotopes also command natural existence in almost all the excavated mineral ores and fos...

Agriculture plays a very important role in influencing major economic sectors of the developing and the developed world and is regarded as one of the most crucial factors in the country’s development. Sustaining quality agriculture production is a necessity particularly of the under-developed, the developing and those countries which are inclined t...

Sulphur dioxide (SO) and particulate matter (PM) are one of the major air pollutants emerging out of the industrial development and human activities. Plants exhibit differential sensitivity to SO 2 pollution and its affect on plant growth can be both direct and/or indirect. The present study was conducted in controlled tunnels to assess the effect...

Sulfur dioxide (SO 2) and particulate matter (PM) are one of the major air pollutants emerging out of industrial development and human activities. Plants exhibit differential sensitivity to SO 2 pollution and its effects on plant growth can be both direct and/or indirect. We have earlier reported that a high SO 2 stress contributes toward the S-nut...

Contribution of stem photoassimilates towards grain filling may have significance under stress, since it may force the plant to initiate an early leaf senescence, thereby limiting the availability of flag leaf photosynthates for grain filling. Radiotracer feeding of ¹⁴C-sucrose to the internode by stem injection method at 20 days stage after anthes...

Two separate experiments were conducted with four bread and two durum wheat cultivars, to test a hypothesis that high ethylene production will alter phytosiderophore production and release dynamics either directly, by competitive partitioning of SAM, or indirectly by causing changes in the root system architecture under iron deficiency. A significa...

Widespread deficiency of soil macro (N) and micro nutrient (Fe) limit crop productivity and nutritional quality of the produce worldwide. Iron is relatively immobile in plants however, its retranslocation can be facilitated by naturally produced chelator in the leaves. Synthesis of these metal-chelators depends on N nutrition of crops. The present...

Assessment of contribution of source towards sink development is very important for deciding pruning intensity and fruit load. In the present study, ¹⁴C-sucrose was used as a tracer to study source–sink carbon flow dynamics in Kinnow, for which branches having one or two fruits were selected and leaves at the proximal or distal position, to the fru...

Legumes have tremendous dietary value for human nutrition. However, the productivity of food legumes is always compromised owing to their insufficient ability to tolerate abiotic stresses such as drought or water logging, marginal soil, low/high temperatures and salt stress. Stress induces changes at the morphological, physiological, biochemical an...
