“…Application of 120-80-100 kg ha −1 of NPK was superior with maximum SYI, whereas the control gave lowest SYI for both rhizome and dry-matter yield based on the regression and PC models.

“…To attain a sustainable crop yield in any soil and agroclimatic condition and to save on chemical fertilizers, it is important that while optimizing the fertilizer doses, changes in soil fertility are also needed to be periodically monitored Vittal et al 2003). Based on the results of long-term experiments reported by Vikas et al (2007Vikas et al ( , 2008 for maize; Behera et al (2007) ;Nema, Maruthi Sankar, and Chauhan (2008) for pearl millet; Mohanty et al (2008) for rice; Sanjay Sharma et al (2009) for soybean; and Anil Sharma et al (2013) for maize, it was observed that the crop yield was significantly influenced by the applied fertilizer doses, apart from a suitable rainfall distribution under rainfed conditions. The authors also observed that if the fertilizer is judiciously applied based on soil fertility of nutrients, maximum sustainable yields could be achieved under any soil and agroclimatic condition.…”

Field experiments were conducted during [2005][2006][2007] to test effects of nineteen treatments on turmeric rhizome yield in Alfisol at Utukur and Inceptisol at Jagtial in India. The treatments were comprised of nitrogen (N) at 0, 60, 120 and 180 kg ha −1 ; phosphorus (P) at 0, 40, 80, and 120 kg ha −1 ; and potassium (K) at 0, 50, 100, and 150 kg ha −1 . Application of 180-120-100 kg ha −1 NPK gave maximum yield of 4302 kg ha −1 in Alfisols, whereas application of 120-80-100 kg ha −1 gave 4817 kg ha −1 in Inceptisols. Regression and principal component (PC) models were calibrated through soil-plant-fertilizer variables. The regression model gave significant R 2 of 0.75 in Alfisols compared to 0.88 in Inceptisols, whereas the PC model explained variance of 66.5 percent in Alfisols and 76.3 percent in Inceptisols. Regression model through PC scores gave R 2 of 0.54 in Alfisols and 0.47 in Inceptisols. Maximum sustainability yield indexes of 58.8 and 55.5 percent by 180-120-120 kg ha −1 (Alfisol) and 67.1 and 60.6 percent Color versions of one or more of the figures in the article can be found online at www. tandfonline.com/lcss. 781 782 D. V. Ramana Reddy et al. by 120-80-100 kg ha −1 (Inceptisol) were attained based on regression and PC models respectively.

“…To evaluate the effects of the organic waste supply, it was used the grain yield, corrected to 13% moisture (wet basis), to calculate agronomic efficiency index (AEI) (Sharma et al, 2013). The AEI of treatments was measured through the formula: AEI = (GYi-GYo)/(GYp-GYo)*100, in which GYi is the observed grain yield of the treatment, GYo is the yield of the control plot without organic amendment inputs and without mineral fertilizer, GYp is the yield reference, which was added only 400 kg ha -1 of NPK mineral fertilizer (04-30-16, with 6.10 of Ca, 2.97 of S, 0.06 of B, 0.97 of Mn and 0.31% of Zn) following the recommendation of Ribeiro et al (1999).…”

The use of organic wastes, as an alternative to inorganic fertilizer, can be an important strategy for Brazilian agriculture. The objective was to evaluate the residual effects and the agronomic efficiency of organic amendments use on chemical attributes of a Haplic Cambisol and to soybean crop. A field experiment was carried out in a completely randomized split-plot design with three replications in Minas Gerais, Brazil, 2008/09. In the plots, the sources of organic amendments were evaluated (poultry litter, farmyard manure, and biochar) using three application rates (3, 6 and 9 Mg ha -1 ) into the subplots, and control treatment without amendments. Agronomic efficiency of the wastes linearly increased with the doses, independent of the organic source. Poultry litter, a nutrient-rich organic amendment, increased the soybean grain yield. The biochar use boosted the availability of calcium and magnesium levels in the soil, and a consequent increase in the sum of bases, base saturation, pH and effective cation exchange capacity of the soil. The poultry litter utilization enhances the soil acidity and availability of potassium, sulfur and zinc, over the time. The use of organic amendments increases the levels of phosphorus, potassium and zinc in the soil, after soybean cropping.Key words: agronomic efficiency index, Glycine max, organic amendments, sustainability Pó de carvão, esterco de curral e cama de frango no cultivo da soja e atributos químicos de um Cambissolo distrófico RESUMO A utilização de resíduos orgânicos, como alternativa ao uso de fertilizantes minerais inorgânicos, pode representar uma importante estratégia para a agricultura brasileira. Objetivou-se, nesse trabalho, avaliar a eficiência agronômica e os efeitos residuais da utilização dos resíduos orgânicos, cama de frango, esterco de curral e pó de carvão nos atributos químicos de um Cambissolo Háplico cultivado convencionalmente com a cultura da soja. O experimento de campo foi realizado em esquema de parcelas subdivididas, utilizando o delineamento em blocos casualizados com três repetições. Nas parcelas foram avaliadas as fontes dos resíduos orgânicos e, nas subparcelas, as doses dos resíduos (3, 6 e 9 Mg ha -1 ), mais o tratamento controle sem resíduos, na safra 2008/09, em Itutinga, MG, Brasil. Verificou-se que a eficiência agronômica dos resíduos aumentou com a elevação das doses, independente da fonte utilizada. A cama de frango, um resíduo orgânico rico em nutrientes, apresentou eficiência agronômica para elevar a produção de grãos de soja, sendo este resíduo orgânico mais eficiente agronomicamente que esterco de curral e pó de carvão. O uso do pó de carvão proporciona aumentos nos níveis de cálcio e magnésio do solo, com consequente elevação da soma de bases, saturação por base, pH e CTC efetiva do solo. Por sua vez, a utilização de cama de frango eleva a acidez e a disponibilidade de potássio, enxofre e zinco no solo, em curto prazo. Em geral, a aplicação de resíduos orgânicos proporciona incrementos nos níveis residuais de fósfo...

Experiments were conducted to test the superiority of treatment combinations of nitrogen (N; 0, 50, 100, 150, 200 kg ha −1 ), phosphorus (0, 30, 60, 90 kg ha −1 ) and potassium (0, 30, 60 kg ha −1 ) for finger millet during 2005-2007. Application of 200-90-60 kg ha −1 gave maximum yield of 1666, 1426 and 1640 kg ha −1 in 3 years, respectively. The yield regression model through soil and fertilizer nutrients gave predictability of 0.98, 0.97 and 0.98, with sustainability yield index (SYI) of 50.4, 49.4 and 52.5 in 2005, 2006 and 2007, respectively. Optimum nitrogen, phosphorus and potassium (NPK) doses for attaining yields of 800 and 1200 kg ha −1 were derived at soil nitrogen, phosphorus and potassium of 75-400, 10-70 and 150-750 kg ha −1 . Fertilizer nitrogen, phosphorus and potassium ranged from 30-128, 3-19, 13-25 kg ha −1 and 105-203, 4-32, 27-39 kg ha −1 for attaining 800 and 1200 kg ha −1 yield, respectively. The doses could be adopted for attaining sustainable yields under semiarid Alfisols. ARTICLE HISTORY
