“…These results are well within the range as reported earlier i.e. 36.2 to 68.4 kg rice grain kg P -1 and 38.3 to 76.5 kg wheat grain kg P -1 (Singh et al 2014) at different locations across India. The main effect of Zn levels averaged over P levels also significantly (p<0.05) influenced AEP in wheat and it decreased from 61.8 to 21.0 kg grain kg applied P -1 when Zn rate increased gradually from 2.5 to 5.0 kg ha -1 .…”

“…On the other hand, the aerobic growing environment and low temperatures during wheat growing season slows the dissolution of occluded P that reduces the availability of P, leading to relatively higher response of wheat to P. Thus, higher PUE by wheat illustrated that P is best used when applied to wheat. Singh et al (2014) also reported the greater efficiency of applied P in wheat compared to rice. The PUE was found to decrease when Zn rate increased gradually from 2.5 to 5.0 kg Zn ha -1 (Fig 3a).…”

Rice-wheat rotation is the most important cropping system of the Indo-Gangetic plains. On-farm experiment was conducted to reveal the effect of Zn fertilization on yield, uptake of nutrient, utilization efficiency (UE) and grain output per unit of fertilizer use through agronomic efficiency (AE) of P and Zn in rice-wheat rotation. The experiment was conducted with rice (cv. Pusa Basmati 1) and wheat (cv. UP-2425) by imposing twelve treatments involving four different doses of P (0, 20, 40 and 60 kg P 2 O 5 ha -1 ) and three different doses of Zn (0, 2.5 and 5.0 kg Zn ha -1 ) with three replications. The yield of basmati rice was not significantly influenced by P×Zn interactions however, for wheat, a conjoint dose of 60 kg P 2 O 5 and 5 kg Zn ha -1 gave the highest grain yield (5.43 t ha -1 ). Phosphorus utilization efficiency (PUE) of wheat was higher compared to basmati rice however, the reverse was true for zinc utilization efficiency (ZUE). Utilization efficiencies of the two nutrients diminished as their rate of fertilization increased, in both the crops. The AE of applied nutrients, in basmati rice varied from 31.4 to 49.7 kg grain kg -1 P and from 43.2 to 121 kg grain kg -1 Zn. In wheat, AE for P varied from 26.9 to 65.5 kg grain kg -1 and for Zn from 56.4 to 83 kg grain kg -1 . In conclusion, the utilization and agronomic efficiency of P in basmati rice can be increased by using 40 kg P 2 O 5 and 2.5 kg Zn ha -1 .

“…Beside crop establishment method, the economic cultivation of rice crop on a sustainable basis also relies on N, the most yield-limiting nutrient, and its management (Singh et al 2014). The increasing rate of N fertilizer either in basal or in the split application treatments increased the cost of production irrespective of the production system (Table 7).…”

The major challenge in sustainable rice production is to achieve the goals of increasing crop productivity, profitability, and resource use efficiency. Production systems (PS) and nitrogen (N) management patterns are two key agronomic practices influencing crop performance, profitability, water use efficiency (WUE), and N use efficiency (NUE). So, this study was conducted to check the influence of split application of N on rice productivity, NUE and profitability under dry direct-seeded rice (DDSR) and transplanted rice (TPR) systems. A field study was conducted in the summer season of 2017 and 2018 to investigate the influence of two PS (dry direct-seeded rice = DDSR and transplanted rice = TPR) and six N management treatments (N 1 = control, N 2 = 50 kg N ha −1 as basal, N 3 = 100 kg N ha −1 as basal, N 4 = 150 kg N ha −1 as basal, N 5 = 100 kg N ha −1 in three splits and N 6 = 150 kg N ha −1 in three splits) on crop productivity, profitability, and resource use efficiency. Yield-related traits, spikelet sterility, WUE, and profitability aspects were significantly influenced by PS. All aspects of crop performance, kernel quality, N uptake, and NUE (except NUE on biomass basis = NUEB) were affected by N management pattern, while no significant interaction between PS and N management was observed for any aspect. On average, DDSR improved the productive tiller density (26%), biological yield (16%), WUE (14%), and NUEB (27%) as compared with TPR. Similarly, DDSR reduced the cost of production (31-43%), while maintaining statistically similar paddy yields and reducing total water inputs (5-17%) in comparison with TPR. Among N management pattern, 100 kg N ha −1 in three splits increased paddy yields (44%), and WUE (42%) as compared with the basal application of 100 kg N ha −1. Similarly, application of N at 100 kg ha −1 in three splits improved the total N uptake (42%), agronomic NUE (146%), apparent recovery efficiency (226%) while reducing the spikelet sterility (28%) as compared with the basal application of 100 kg N ha −1. The DDSR has the potential to maintain or increase yield, WUE, NUE, and economic returns. While, split application of N at 100 kg ha −1 either in DDSR or TPR not only increased the SPADchlorophyll value, WUE, NUE, and economic returns but also reduced the spikelet sterility.

“…Prior to establishing nutrient management strategies, geographic, meteorological, and soil conditions must be taken into consideration (Duan et al, 2014) since they exert a direct influence on crop yield. Singh et al (2014) studied the optimization of nutrient management techniques in rice and wheat crops in India and highlighted the significance of crop demand, soil nutrient availability, and environmental conditions on these crops' agronomic efficiency. Hejcman et al (2012) assessed sustainability in winter wheat production after 50 years of fertilization with nitrogen, phosphorus, and potassium in the Czech Republic.…”

This study aimed at assessing the effects of nitrogen-potassium interaction on dry matter and grain yield of irrigated wheat (Triticum aestivum L.) grown in the Brazilian Cerrado. The experiment was conducted for two consecutive cropping seasons (2014 and 2015), between March and August. The experiment was arranged in a randomized block design. Treatments consisted of five nitrogen and five potassium doses in a factorial scheme (5×5). The analyzed variables consisted of the shoot and spike dry weights, and grain yield. In both years (2014 and 2015), isolated effects of nitrogen and potassium doses were observed on the assessed traits. In 2014, the highest results were achieved by the respective nitrogen and potassium doses: 145.02 and 148.32 kg ha -1 for shoot dry weight, 133.79 and 139.85 kg ha -1 for spikes, and 119.14 and 138.83 kg ha -1 for grain yield. Yet in 2015, no significant results were identified, while nitrogen doses showed a linear effect on shoot and spike dry weights, potassium rates revealed such effect on grain yield. Although nitrogen showed a higher response in terms of dry weight for shoot and spikes, potassium induced the largest increases in productivity. Thus, for greater efficiency of fertilization, a careful analysis of the level of soil fertility, the expected productivity and the technological level employed is necessary. It should be emphasized that the management of fertilization has specificities every year, requiring constant adaptation.Keywords: BRS 254 wheat; Cerrado wheat production; nitrogen-potassium ratio; nitrogen and potassium fertilizations; Triticum aestivum.
