“…The enhancement in both grain and straw yield of STCR -IPNS 3.5 t ha -1 is due to the balanced supply of nutrients through the combined application of inorganic fertilizers along with organic manure viz., FYM. It deliberately emphasizes that crop meets the immediate nutrient requirement through inorganic fertilisers and the nutrient requirement for later growth stages has been met by organic manures which had significant effect not only in improving the yield but also in reducing the nutrient losses to the environment thus managing the optimum nutrient supply (Manik et al, 2019). Similar results were reported by Suresh and Santhi (2018) in maize and Ravikiran et al (2018) in pearl millet on black calcareous soils.…”

The present investigation was undertaken to validate the Inductive cum Targeted yield model based Fertiliser Prescription Equations (FPEs) developed under Soil Test Crop Response based Integrated Plant Nutrition System (STCR-IPNS) for desired yield target of pearl millet (var CO 10) on a mixed black calcareous soil (Periyanaickenpalayam soil series-Vertic Ustropept). The field experiment was conducted during Kharif 2019 at TNAU Farm, Coimbatore, and was laid out in a randomized block design with ten treatments that were replicated thrice. The results emanated from the field experiment brought forth the fact that the various growth and yield attributes of pearl millet were significantly influenced by STCR treatments as compared to blanket treatments. There was a +10% variation in achievement of yield targets proving the validity of the fertiliser prescription equations developed for desired yield target of pearl millet (var CO 10) on a mixed black calcareous soil. Using the data on grain yield and quantity of nutrients applied, the various parameters viz., per cent achievement, response ratio and benefit: cost ratio were computed. Among the treatments, STCR-IPNS-3.5 t ha-1 has demonstrated its supremacy by registering higher grain yield of 3455 kg ha-1 with a relatively higher response ratio of 12.57 kg kg-1 and BCR of 1.94. STCR-IPNS-3.5 t ha-1 has recorded a yield increase of 43.1, 21.2 and 74.6 per cent over blanket (100% RDF), blanket plus FYM 12.5 t ha-1, and farmer's practice respectively and the increase in response ratio was 4.28, 1.18 and 5.27 kg kg-1 respectively. Therefore, for achieving higher grain yield, nutrient uptake, response ratio, and BCR in pearl millet (var CO 10) on a mixed black calcareous soil (Periyanaickenpalayam soil series-Vertic Ustropept), STCR-IPNS based fertiliser prescriptions can be followed.

Climate variation and change are an unavoidable phenomenon faced by the natural habitat of this planet. For getting potential yield from vegetable crops under the changing climate conditions, the practical strategies at field level can serve as a guideline for the farmers. Moreover, there are several strategies available for mitigating the harmful effects of climate change. In this manuscript, efforts have been made for reviewing the mitigating strategies against the impact of climate change in vegetable crops via conventional approaches. Considering the situation, the information reviewed revealed that significant result of conventional approaches with climate-smart adoptions strategies has a direct bearing on vegetable production for the increasing population in frenziedly changing climate scenario.

“…It is believed that at least 10% of arable fields can be affected by flooding (FAOSTAT, ). As such, it concerns many cultivated species, including major crops, like wheat, and alternative agricultural practices have to be found to overcome this problem (reviewed in Manik et al, 2019 [ 3 ]). Flooding leads to occasional or prolonged root submergence (waterlogging).…”

Root oxygen deficiency that is induced by flooding (waterlogging) is a common situation in many agricultural areas, causing considerable loss in yield and productivity. Physiological and metabolic acclimation to hypoxia has mostly been studied on roots or whole seedlings under full submergence. The metabolic difference between shoots and roots during waterlogging, and how roots and shoots communicate in such a situation is much less known. In particular, the metabolic acclimation in shoots and how this, in turn, impacts on roots metabolism is not well documented. Here, we monitored changes in the metabolome of roots and shoots of barrel clover (Medicago truncatula), growth, and gas-exchange, and analyzed phloem sap exudate composition. Roots exhibited a typical response to hypoxia, such as γ-aminobutyrate and alanine accumulation, as well as a strong decline in raffinose, sucrose, hexoses, and pentoses. Leaves exhibited a strong increase in starch, sugars, sugar derivatives, and phenolics (tyrosine, tryptophan, phenylalanine, benzoate, ferulate), suggesting an inhibition of sugar export and their alternative utilization by aromatic compounds production via pentose phosphates and phosphoenolpyruvate. Accordingly, there was an enrichment in sugars and a decline in organic acids in phloem sap exudates under waterlogging. Mass-balance calculations further suggest an increased imbalance between loading by shoots and unloading by roots under waterlogging. Taken as a whole, our results are consistent with the inhibition of sugar import by waterlogged roots, leading to an increase in phloem sugar pool, which, in turn, exert negative feedback on sugar metabolism and utilization in shoots.
