“…The apparent nitrogen recovery (R) depends on the congruence between plant demand for N and the quantity of this nutrient released from N fertilizer applied [59]. The R value in cereals, including wheat, ranges from 30% to 50%, and with lower N doses and best nutrient management it could reach 50-80% [61]. A low R value entails economic and ecological effects.…”

Optimization of fertilization enables to obtain a yield of high quality and quantity, brings economic profits, and reduces environmental threats. The aim of the three-year field experiment was to determine the efficiency of fertilization with a new fertilizer available on the Polish market and containing nitrogen (N) and sulfur (S) in proportions designed for cereals cultivation (30% N and 6% S as ammonium nitrate and ammonium sulfate). Other treatments included no fertilization; fertilization with ammonium nitrate (34% N); fertilization with standard nitrogen and sulfur fertilizer with N supplementation with ammonium nitrate. Nitrogen doses were 150, 200, and 250 kg N ha−1. Sulfur was applied in doses of 30, 40, and 50 kg S ha−1. A beneficial effect of using fertilizer containing N and S in proportions designed for cereals cultivation was observed. The highest mean optimal nitrogen dose and maximum winter wheat yield were recorded for the new fertilizer (217 kg N ha−1 and 8251 kg ha−1, respectively). Sulfur supplementation with the new fertilizer significantly increased apparent nitrogen recovery (mean values 48.9%, 44.6%, and 40.6% for doses 150, 200, and 250 kg N ha−1, respectively), agronomic efficiency (11.1 and 8.6 kg kg−1 N for doses 200 and 250 kg N ha−1, respectively), and physiological efficiency (24.7 kg kg−1 N for dose 200 kg N ha−1).

Functional crop diversity enhances crop productivity, stability, and food security through efficient nutrient cycling and water utilization; however, performance is variable under marginal environments. We applied stability analysis to assess impacts of grain legume integration on maize (Zea mays L.) grain yield, yield stability, N use efficiency (NUE), and ability to meet household protein requirements. Six field trials were conducted across three agroecological zones over five cropping seasons. We used additive main effect and multiplicative interaction to assess grain yield stability of maize in unfertilized maize, maize fertilized with 69 kg N ha−1 (Mz69), maize–pigeonpea [Cajanus cajan (L.) Millsp.] intercrop (MzPp), and maize in rotation with soybean [Glycine max (L.) Merr.] (SbRot), peanut (Arachis hypogaea L., PnRot), and peanut–pigeonpea intercrop (PnDLR). Maize in rotation or intercrop received 10.5 kg P2O5 and 35 kg N ha−1, whereas the Mz69 treatment received 21 kg P2O5 and 69 kg N ha−1. Maize grain yield in rotation with legumes was not significantly different from yield for Mz69. In wetter environments, MzPp intercrops had low maize grain yield (−35%) relative to Mz69, whereas in drier environments, maize had higher grain yield (14%) relative to rotated maize. Rotating maize with legumes increased NUE (56%) and protein contributions (65%) relative to Mz69. Grain yield of maize in SbRot consistently had the highest yield and was the most stable technology. Simple statistical models can be used to test multicrop stability. Integrating maize with legumes as intercrops or rotation can allow farmers to achieve high and stable yield under varying rainfall, with modest fertilizer investments.

“…Across all nutrient management strategies, there were differences in the total uptake of both [45][46][47]32]. Other studies have acknowledged that the application of micronutrients is known to also increase the use efficiency of macronutrients [16] and also enhances higher macronutrients apparent recoveries [48].…”

To close the nutrient-related yield gaps in maize, balanced nutrition using primary and secondary macronutrients as well as micronutrients is recommended. Multi-nutrient diagnostic field trials were conducted in Guinea Savanna of Nigeria to assess the interactive effects of macronutrients and micronutrients on maize grain yields, nutrient uptake as well as N, P and K use efficiencies. The treatments consisted of a control (zero fertilizer applied), an NPK treatment and 10 other treatments in which macronutrient (Mg, S) and/or micronutrients (B, and Zn) were added to the NPK. The experiment was laid out in Randomized Complete Block Design with 3 replications. Data collected were subjected to mixed model with nutrient management strategy as fixed effects while replication nested in location and interaction between location and nutrient management strategy as random effects. The results revealed significant effects (P < 0.05) of nutrient management strategy on maize yield, nutrient uptake and nutrient use efficiencies of N, P and K. The study revealed that yield advantage over the recommended NPK fertilizer as a result of application macronutrients and micronutrients were highest with Mg in Lere (2.4 t ha−1), S + B + Zn in Faskari (2.8 t ha−1), S + B in Doguwa (1.5 t ha−1) and S + Zn in Toro (2.4 t ha−1).  Addition of Mg, S and B significantly increases macronutrient uptakes over the recommended NPK only. Agronomic use efficiency, internal utilization efficiency, apparent recovery efficiency and partial factor productivity were significantly increased with the addition of S, Mg, and B but were not improved with Zn application. It was concluded that nutrient limitations to maize in the Guinea Savanna go beyond N, P and K. This study recommends that S, Mg, and B are needed to improve maize productivity and engender improve the use efficiency of NPK fertilizers.
