“…Earlier reports showed that increased application of nitrogen significantly increased stem length in chrysanthemum (Patel and Chaudhari, 2011), 9 in China aster (Gaikwad et al, 2004)10 and in bird of paradise (Disha, 2016). 11 Improvement in fresh weight might be due to improved vegetative growth of plant under appropriate level of nitrogen which caused more storage of carbohydrates resulting improved fresh weight.…”

“…Similar results were obtained by Chauhan (2012) 12 in golden rod and Ahirwar et al, (2012) 13 in African marigold. The improvement in vase life might be due to nitrogen which produces carbohydrates that extend the vase life but with increase in nitrogen, depletion of carbohydrates causing digestion of proteins which might reduce sugar content, an important factor to extend vase life in chrysanthemum as stated by Disha (2016) 11 in bird of paradise and Patel and Chaudhari (2011) 9 in chrysanthemum.…”

An investigation was carried out to study the effect of nitrogen and phosphorus on growth, flowering and yield of cut chrysanthemum cv. Thai Chen Queen. The experiment was laid out in randomized block design (RBD) with factorial concept comprising of twelve treatment combinations with four levels of nitrogen, viz., 100 kg N/ha (N1), 150 kg N/ha (N2), 200 kg N/ha (N3) and 250 kg N/ha (N4) and three levels of phosphorus, viz., 50 kg P2O5/ha (P1), 75 kg P2O5/ha (P2) and 100 kg P2O5/ha (P3). The treatments were replicated four times. The results indicated that application of 200 kg N/ha (N3) to cut chrysanthemum was most effective to increase plant height whereas, plants receiving 150 kg N/ha significantly improved vegetative growth as well as quality and yield of flowers. Application of 75 kg P2O5/ha was found promising for growth, quality as well as yield parameters.

“…Phosphorus is not only a structural element of cell organelles (such as mitochondria and chloroplast) but also the primary constituent of phospholipids (ATP and NADPH) that are used for energy metabolism in light and dark reactions. Indeed, P is indispensable for plant photosynthesis and respiration, such that changes in the P concentration available for plant uptake would alter their vegetative and reproductive growth (George et al, 2016; Patel et al, 2017). An external P addition usually tends to enhance plants’ internal P concentration, accelerating their photosynthetic efficiency and thus promoting biomass accumulation (Graciano et al, 2006; Suriyagoda et al, 2014).…”

Previous studies have demonstrated changes in plant growth and reproduction in response to nutrient availability, but responses of plant growth and reproduction to multiple levels of nutrient enrichment remain unclear. In this study, a factorial field experiment was performed with manipulation of nitrogen (N) and phosphorus (P) availability to examine seed production of the dominant species, Stipa krylovii, in response to N and P addition in a temperate steppe. There were three levels of N and P addition in this experiment, including no N addition (0 g N m−2 year−1), low N addition (10 g N m−2 year−1), and high N addition (40 g N m−2 year−1) for N addition treatment, and no P addition (0 g P m−2 year−1), low P addition (5 g P m−2 year−1), and high P addition (10 g P m−2 year−1) for P addition treatment. Low N addition enhanced seed production by 814%, 1371%, and 1321% under ambient, low, and high P addition levels, respectively. High N addition increased seed production by 2136%, 3560%, and 3550% under ambient, low, and high P addition levels, respectively. However, P addition did not affect seed production in the absence of N addition, but enhanced it under N addition. N addition enhanced seed production mainly by increasing the tiller number and inflorescence abundance per plant, whereas P addition stimulated it by decreasing the plant density yet stimulating height of plants and their seed number per inflorescence. Our results indicate seed production is not limited by P availability but rather by N availability in the temperate steppe, whereas seed production will be increased by P addition when N availability is improved. These findings enable a better understanding of plant reproduction dynamics in the temperate steppe under intensified nutrient enrichment and can inform their improved management in the future.

Previous studies have demonstrated changes in plant growth and reproduction in response to nutrient availability, but how investigations of such responses to multiple levels of nutrient enrichment remains unclear. In this study, we manipulated nitrogen (N) and phosphorus (P) availability to examine seed production responses to three levels each of N and P addition in a factorial experiment: no N addition (0 g N m-2 yr-1), low N addition (10 g N m-2 yr-1), high N addition (40 g N m-2 yr-1), and no P addition (0 g P m-2 yr-1), low P addition (5 g P m-2 yr-1), high P addition (10 g P m-2 yr-1). Low N addition enhanced seed production by 814%, 1371%, and 1321% under ambient, low, and high P addition levels, respectively. High N addition increased seed production by 2136%, 3560%, and 3550% under ambient, low, and high P addition levels, respectively. However, P addition did not affect seed production in the absence of N addition, but it did enhance it under N addition. Furthermore, N addition enhanced seed production mainly by increasing the tiller number and inflorescence abundance per plant, whereas P addition stimulated it by decreasing the plant density yet stimulating height of plants and their seed number per inflorescence. Our results indicate seed production is limited not by P but rather by N in the temperate steppe, whereas seed production will be increased by P addition when N availability is improved. These findings enable a better understanding of plant reproduction dynamics of steppe ecosystems under intensified nutrient enrichment and can inform their improved management in the future.
