The primary objectives of modern agriculture includes the environmental sustainability, low production costs, improved plants’ resilience to various biotic and abiotic stresses, and high sowing seed value. Delayed and inconsistent field emergence poses a significant threat in the production of agri-crop, especially during drought and adverse weather conditions. To open new routes of nutrients’ acquisition and revolutionizing the adapted solutions, stewardship plans will be needed to address these questions. One approach is the identification of plant based bioactive molecules capable of altering plant metabolism pathways which may enhance plant performance in a brief period of time and in a cost-effective manner. A biostimulant is a plant material, microorganism, or any other organic compound that not only improves the nutritional aspects, vitality, general health but also enhances the seed quality performance. They may be effectively utilized in both horticultural and cereal crops. The biologically active substances in biostimulant biopreparations are protein hydrolysates (PHs), seaweed extracts, fulvic acids, humic acids, nitrogenous compounds, beneficial bacterial, and fungal agents. In this review, the state of the art and future prospects for biostimulant seedlings are reported and discussed. Biostimulants have been gaining interest as they stimulate crop physiology and biochemistry such as the ratio of leaf photosynthetic pigments (carotenoids and chlorophyll), enhanced antioxidant potential, tremendous root growth, improved nutrient use efficiency (NUE), and reduced fertilizers consumption. Thus, all these properties make the biostimulants fit for internal market operations. Furthermore, a special consideration has been given to the application of biostimulants in intensive agricultural systems that minimize the fertilizers’ usage without affecting quality and yield along with the limits imposed by European Union (EU) regulations.

Food-based components represent major sources of functional bioactive compounds. Milk is a rich source of multiple bioactive peptides that not only help to fulfill consumers ‘nutritional requirements but also play a significant role in preventing several health disorders. Understanding the chemical composition of milk and its products is critical for producing consistent and high-quality dairy products and functional dairy ingredients. Over the last two decades, peptides have gained significant attention by scientific evidence for its beneficial health impacts besides their established nutrient value. Increasing awareness of essential milk proteins has facilitated the development of novel milk protein products that are progressively required for nutritional benefits. The need to better understand the beneficial effects of milk-protein derived peptides has, therefore, led to the development of analytical approaches for the isolation, separation and identification of bioactive peptides in complex dairy products. Continuous emphasis is on the biological function and nutritional characteristics of milk constituents using several powerful techniques, namely omics, model cell lines, gut microbiome analysis and imaging techniques. This review briefly describes the state-of-the-art approach of peptidomics and lipidomics profiling approaches for the identification and detection of milk-derived bioactive peptides while taking into account recent progress in their analysis and emphasizing the difficulty of analysis of these functional and endogenous peptides.

A long-term field experiment started in 1995 on Research Farm of Department of Soil Science, CCS Haryana Agricultural University Hisar (India) was selected to study the effects of organic manures and chemical fertilizers on productivity, seed quality and nutrient use efficiency of wheat under pearl millet-wheat cropping system. The organic manures (15 Mg FYM, 5 Mg poultry manure and 7.5 Mg pressmud) were applied alone and in combination with fertilizers (150 kg N + 30 kg P 2 O 5 ha -1 ) and compared with chemical fertilizers applied alone (150 kg N + 60 kg P 2 O 5 ha -1 and 75 kg N + 30 kg P 2 O 5 ha -1 ). The results showed that the application of organic manures in combination with N and P fertilizers significantly increased all yield attributes, i.e. plant height, number of tillers/m row length, spike length, number of grains/spike. Higher grain yield of wheat (61.4, 57.4 and 62.7 q ha -1 ) was observed when recommended dose of N and half of P was applied in conjunction with FYM, poultry manure and pressmud, respectively. Grain yield of wheat increased by 13.5, 6.1 and 15.9%, respectively, under same treatments when compared with recommended dose of N and P fertilizers. Among the organic manures, highest yield (32.9 q ha -1 ) was obtained with pressmud application. However, application of organic manures alone resulted in poor yield and even lower than 50% recommended dose of N and P fertilizer. All the seed quality parameters (standard germination, shoot length, root length, seedling dry weight, seedling vigour index-I and -II) improved with the combined application of organic manures and chemical fertilizers as compared to their individual application. The partial factor productivity of N and P increased with combined application organic manures and chemical fertilizer as compared to chemical fertilizers applied alone, however, nutrient harvest index and their utilization efficiency decreased with combined application of organic manures and fertilizers as compared to their individual application.
