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.

AbstractBread wheat (Triticum aestivum L.) is one of the most important cereal crops in Ethiopia. The productivity of wheat is markedly constrained by nutrient depletion and inadequate fertilizer application. The experiment was conducted to study the effect of nitrogen (N) and potassium (K) fertilizer rates on growth, yield, nutrient uptake and use efficiency during 2019 cropping season on Kedida Gamela Woreda, Kembata Tembaro Zone Southern Ethiopia. Factorial combinations of four rates of N (0, 23, 46 and 69 kg Nha−1) and three rates of K2O (0, 30 and 60 kg Nha−1) in the form of urea (46–0-0) and murate of potash (KCl) (0-0-60) respectively, were laid out in a randomized complete block design with three replications. The results showed that most parameters viz yield, yield components, N uptake and use efficiency revealed significant differences (P < 0.05) due to interaction effects of N and K. Fertilizer application at the rate of 46 N and 30 kg K ha−1 resulted in high grain yield of 4392 kg ha− 1 and the lowest 1041 from control. The highest agronomic efficiency of N (52.5) obtained from the application of 46 kg N ha−1. Maximum physiological efficiency of N (86.6 kg kg−1) and use efficiency of K (58.6%) was recorded from the interaction of 46 and 30 kg K ha−1. Hence, it could be concluded that applying 46 and 30 kg K ha−1was resulted in high grain yield and economic return to wheat growing farmers of the area. Yet, in order to draw sound conclusion, repeating the experiment in over seasons and locations is recommended.

The experiment was conducted to measure crop yields, nutrient concentration, nutrient uptake and balance by using different nutrient management practices for mustard-mungbean-T. aman rice cropping system in calcareous soil of Madaripur, Bangladesh. Different nutrient management practices were absolute nutrient control (T1); farmer’s practice (T2); AEZ based nutrient application (T3) and soil test based nutrient application (T4). The practices were compared in a randomized completely block design with three replications over two consecutive years. The average yield through application of soil test based nutrient (T4) was showed effective to get highest yields of mustard (1530 kg ha-1), mungbean (1632 kg ha-1) and T. aman rice (4729 kg ha-1). The same practices (T4) exhibited the greatest nutrients uptake by the test crops. The apparent balance of N and K was negative; however it was less negative and less deficiency detect in T4 treatment. Positive balance of P observed in all practices except in T1. There was a positive S balance (7.60 kg ha-1) in T4 but negative in T1, T2 and T3. Zinc balance was found positive in T3 and T4 and negative in T1 and T2. Boron balance in the system was neutral or slightly positive in T1 and negative in T2 but positive in T3 and T4. Organic matter, N, P, S, Zn and B status in soil was improved by T4 treatment. The results suggested that the soil test based nutrient application is viable and sustainable for mustard-mungbean-T. aman rice cropping system in calcareous soils of Bangladesh.

Abstract The functional types of plants (PFT) ecological approach could be used to link the preferences of ruminants. In order to investigate if ruminant preferences were associated with this approach, three PFT groups were evaluated. A group “B”, represented by Paspalum urvillei (PU-B), “C” by Nassella neesiana (NN-C) and Sporobolus indicus (SI-C) and “D” by Andropogon lateralis (AL-D). In a randomized block design with repeated measures over time, two independent cafeteria trials (autumn-winter, A-W, and spring-summer, S-S) were carried out in calves (n = 8 for A-W; n = 4 for S-S; BW=240–270 kg) arranged in four pens. In three sessions of ten minutes each, calves received 120–160 gDM of fresh cut leaves from the different species. Dry matter intake (DMI), nitrogen intake (NI) and neutral detergent fiber intake (NDFI) were measured. Data were analyzed with a mixed model that included specie and session as fixed effects and blocks as a random. The statistical analyses were performed with SAS (University Edition), data is expressed as lsmeans and was considered to differ when Tukey test presented P &lt; 0.05. No significant differences were observed between sessions. The DMI and NI were higher in NN-C and lower in AL-D (P &lt; 0.01) during A-W. However, in S-S, higher DMI and NI were observed in AL-D and SI-C while NN-C presented the lower DMI and NI (P &lt; 0.01). The FDNI did not show differences in A-W meanwhile in S-S was positively associated with DMI (Table1). Interestingly, when the season changed, it was observed a change in PFT preference, in A-W calves preferred NN-C whereas in S-S preferred AL-D. However, attributes associated with preferences were maintained in both stations, for instance, higher DMI was associated with higher NI. Additional research is required on the interactions between PFT approach and the preference of animals for different species.

The integrated use of chemical and organic fertilizers can help in sustainable and environmentally sound nutrient management of soils. A study was conducted in the farmer’s field of Godaghari, Rajshahi from February to May 2012 to investigate the effect of integrated nutrient management on nutrient uptake by rice cv. NERICA 10 and economization of inputs. Six treatments viz. T1 = Control, T2 = RFD for MYG + cowdung @ 5 t ha-1, T3 = RFD for HYG, T4 = RFD for HYG + cowdung @ 5 t ha-1, T5 = RFD for HYG + cowdung @ 5 t ha-1 based on IPNS, and T6 = RFD for HYG + 10% excess fertilizer of HYG were used. The experiment was laid out in a randomized complete block design with three replications. Results showed that the uptake of N, P, K, S, Ca and Mg by both grain and straw of rice were statistically significant due to use of integrated nutrient management. The highest nutrient uptake was recorded from the treatment T5 and the lowest value was obtained from control. Combined application of cowdung @ 5 t ha-1 along with recommended chemical fertilizers based on IPNS was more economic compared to other treatments because maximum benefit cost ratio was calculated from this treatment. The overall results suggest that integrated nutrient management can be used as an alternate option of chemical fertilization to achieve maximum yield, nutrient uptake and cost of return for rice cv.

Poor agronomic management such as nutrient management and plant density are critical challenges of lentil production in Ethiopia. Therefore, this study was conducted to determine the effects of different row spacing and phosphorus (P) applications on the seed yield of lentil at Ude and Minjar, in 2017 up to 2019. The experiment was conducted in completely randomized block design with three replications. The treatments were comprised of a factorial arrangement of three levels of row spacing (20, 30 and 40 cm) and four levels of P fertilizer (0, 30, 60 and 90 kg P2O5 ha-1). The result revealed that at Ude, the row spacing x P fertilizer interactions was a significant effect on the biomass, seed, and haulm yield of lentil. However, at Minjar; only the main effects of row spacing and P fertilizer had a significant effect on biomass, seed, and haulm yield. Phosphorus agronomic use efficiency was significantly influenced by the interaction of row spacing and P fertilizer. As a result, the highest phosphorus agronomic use efficiency was recorded at 30 kg P2O5 ha-1coupled with 20 cm row spacing at both locations. The economic analysis revealed that 20 cm row spacing and 30 kg P2O5 ha-1fertilizer managements gave the highest net benefit and acceptable marginal rate of return (MRR) as compared to other practices at both locations. Therefore, 20 cm row spacing and 30 kg P2O5 ha-1rate of fertilizer would be recommended to enhance the productivity of lentil in the study areas.

Use Efficiency

Nutrient use efficiency (NUE) is an important concept in the evaluation of crop production systems. With emerging nutrient deficiencies under intensive agriculture, there is a need to improve NUE. One of the approaches to enhance it is by judicious use of fertilizers (adequate rate, effective source, methods and time of application) as well as inclusion of organic manures. Organic nutrient sources are very effective but as their availability is not sufficient to meet the nutrient demand, we have to integrate both organic and inorganic sources of nutrients together in order to achieve higher NUE. Common measures of NUE include Partial Factor Productivity (PFP), Agronomic Efficiency (AE), Apparent Recovery Efficiency (RE), Physiological Efficiency (PE) and Internal Utilization Efficiency (IE). Mineral Fertilizer Equivalent (MFE) is another parameter that can be used to assess short term release of nutrients (mainly nitrogen) from organic nutrient sources

A field experiment was undertaken to study the effect of nutrient management on rice cv. Puspa (IET-17509) during pre-kharif season of 2013 and 2014. The experiment was conducted at Rice Research Station, Bankura with eleven different nutrient management practices i.e., N1 = N, P2O5, K2O @ 60, 30, 30 kg ha-1 (RDF);N2 = RDF + Vermicompost @ 2.5 t ha-1; N3 = RDF + FYM @ 5 t ha-1 ; N4 = FYM @ 5 t ha-1, N5 = Vermicompost @ 2.5 t ha-1 ; N6 = RDF + glyricidia (well decomposed) as green manure @ 3 t ha-1; N7 = RDF + ZnSO4 @ 20 kg ha-1 N8 = RDF + borax @ 2 kg ha-1 ; N9 = RDF + Vermicompost @ 2.5 t ha-1 + ZnSO4 @ 20 kg ha-1 ; N10 = RDF +Vermicompost @ 2.5 t ha-1 + borax @ 2 kg ha-1 ; N11 = RDF + Vermicompost @ 2.5 t ha-1 + ZnSO4 @ 20 kg ha-1 + borax @ 2 kg ha-1 respectively in randomized block design comprising of three replications. The result of experiment revealed that rice plot fertilized with the combination of NPK @ 60:30:30 + VC + ZnSO4@ 20 kg ha-1 + borax @ 2 kg ha-1 recorded the highest grain yield of 4.45 t ha-1 which was 56.69 % higher (2.84 t ha-1) than the FYM treated plot. Organic substitution by FYM and vermicompost (VC) had failed to register the significant impact on growth, yield and nutrient uptake. Nutrient uptake and residual nutrient status was also highest in NPK @ 60:30:30 kg ha-1 + VC @ 2.5 t ha-1 + ZnSO4 @ 20 kg ha-1+ borax @ 2 kg ha-1 fertilized plot.

Abstract An alpha-amylase enzyme has the potential to increase starch digestibility, thus improving feedlot cattle performance and efficiency. The objective of this experiment was to evaluate the addition of an alpha-amylase enzyme on two steam-flaked bulk densities and subsequent performance of finishing beef steers. Forty-eight crossbred steers (325 ± 19 kg), were used in a complete randomized block design with a 2 × 2 factorial treatment design. Factors were corn processing and enzyme addition. Dietary treatments were steam-flaked corn-based diets with two bulk-flake density weights of corn (0.32 kg/L vs. 0.39 kg/L). Experimental treatments were 1) 0.32 kg/L with no enzyme (32NE), 2) 0.39 kg/L with no enzyme (39NE), 3) 0.32 kg/L with enzyme (32E), and 4) 0.39 kg/L with enzyme (39E) on a DM basis. The enzyme was applied at 0.50 kg/T of steam-flaked corn (As-fed basis). Data were analyzed using a mixed model with fixed effects of flake weight, enzyme, and flake weight × enzyme interaction. Throughout the feeding period, starch availability for 0.32 kg/L and 0.39 kg/L corn averaged 60.7% and 42.2%, respectively. Steers receiving the alpha-amylase enzyme had no differences in BW (P ≥ 0.62), ADG (P ≥ 0.55), and DMI (P ≥ 0.56) compared to NE steers. Furthermore, carcass characteristics did not differ (P ≥ 0.26) between E and NE steers. Feeding an alpha-amylase enzyme to finishing cattle had no detrimental effects on performance or carcass characteristics. Overall, a more highly processed corn was observed to decrease dry matter intake and increase the potential for digestive upsets. This may limit the use of the alpha-amylase enzyme to a lesser processed corn.

A field experiment was conducted during Kharif 2017 at Devanahalli village, Bengaluru rural district of Karnataka to evaluate the effect of different approaches of nutrient application on yield,  nutrient uptake and use efficiency by carrot (Daucus carota L.). The experiment was laid out in randomized complete block design replicated thrice with eight treatments comprisingT1 (STCR target 20 tha-1  through inorganics), T2 (STCR target 20 tha-1  through integrated), T3 (STCR target 25 tha-1  through inorganics), T4 (STCR target 25 tha-1  through integrated), T5 (RDF (75: 63: 50) N, P2O5, K2O kg ha-1+ FYM), T6 (LMH /STL + FYM), T7 (Farmers practice (92.6:159:0) N, P2O5 kg ha-1 + FYM), T8 (Absolute control).Results revealed that significantly higher root (27.51 t ha-1)  and shoot (16.48 t ha-1) yield were recorded in STCR target of 25 t ha-1 through   integrated approach. Similarly, higher total uptake of nitrogen, phosphorus and potassium  (297.07 kg, 57.48 kg and 253.81 kg ha-1, respectively) by carrot and the higher apparent recovery   efficiency (0.35, 0.08 and 0.58 kg kg-1 of N, P2O5 and K2O, respectively) and agronomic nutrient use efficiency (26.10, 12.37 and 48.25 kg kg-1 of N, P2O5 and K2O, respectively) were recorded in the same STCR target of 25 t ha-1 through integrated approach. However, the better profit was recorded (value cost ratio: 43.30) in STCR target of 25 t ha-1 through inorganics. The STCR target of 25 t ha-1 through integrated approach had the most positive effect for the carrot cultivation.
