“…In general, the available nitrogen concentrations were significantly increased to the same extent in mineral-N and bio-fertilized plots (Table 5). These results are in agreement with the findings of Li et al2001, Scheller andRaupp, 2005;Warman, 2005, Herencia et al, 2007, and Li et al2011.…”

Two plots experiments were conducted at the Soil Salinity and Alkalinity Laboratory at Alexandria, Egypt, to study the beneficial effects of nitrogen supply from soybean intercropped with maize on available nitrogen in soil, nitrogen uptake, and yield of maize. The results indicated that the highest grain yield of maize (5581 kg.ha . Although, the intercropped maize and soybean plus rhizobium at 50% of RR of N fertilizer was not yielded the highest corn grain, it is recommended that to be the best economic treatment.

“…T 6 -T 11 (0.0436-0.0621 t/ha/year) and the residual effect of organic manures applied to rice on the yield slope of succeeding wheat crop was statistically significant. The higher yield slope was due to more conducive plant growth environment under the application of organics as reported by Herencia et al (2007). Efthimiadou et al (2010) enumerated that combined application of mineral and organic source of nutrients enhances the photosynthetic rate and stomatal conductance which are the primary physiological processes responsible for plant dry matter production.…”

We measured the long-term (28 years) sustainability of rice-wheat cropping system under integrated nutrient management practices emphasizing the trends in grain yields, sustainable yield index (SYI) and nutrient budgeting. The data of long-term experiment revealed that grain yield of both rice and wheat declined under control and sub-optimal fertilizer inputs (50% or 75% recommended fertilizer NPK). Negative yield trend (slope) was observed in control plots for rice (-0.0296) and wheat (-0.0070); whereas positive yield trend was observed under treatments receiving organic supplements. The SYI values indicate that rice yields are more sustainable than wheat. Data on apparent nutrient balance showed a deficit of N (-42.2 kg/ha/year), P (-9.1 kg/ha/year) and K (-52.2 kg/ha/year) under control plots. Surprisingly, there was net depletion of K under the organic supplemented plots. Correlation study revealed that apparent balance of K was negatively correlated with SYI (r = -0.921 for rice; r = -0.914 for wheat) and yield slope (r = -0.870 for rice; r = -0.896 for wheat). If the trend of K imbalance is not reversed, the potential to improve N and P fertilizer use efficiency and crop yields will be limited.

The growth, phenology and fruit yield of 14 Japanese plum cultivars (Prunus salicina Lindl) were studied in two newly established experimental orchards under organic and conventional management. The experiment was conducted during 2005-2011 in the province of Seville (SW Spain), an important region of Japanese plum culture. Trunk crosssection areas (TCSA), flowering, yield and tree defoliation before winter dormancy were analysed over several years. After one year, TCSA were larger in the organically managed orchard (OMO) for most of the cultivars, in the next two years they were equal, and from the fourth year, several cultivars showed significantly larger TCSA in the conventionally managed orchard (CMO). Flowering in the conventional orchard started from 2 to 6 days before and lasted for 3 to 5 days more than in the OMO. Several cultivars produced significantly more fruit in the CMO, being the average fruit yield in the organic orchard about 72% of the conventionally managed orchard. Autumn defoliation was significantly advanced in the organic orchard, especially in cultivars highly susceptible to rust (Tranzschelia pruni spinosae), a disease not adequately controlled in the organic orchard.
