“…This indicated that (GM) provided a substantial portion of N requirements in sorghum. Similar results were reported by Kurdali [25] and Malik et al [37] using different kinds of green manure. The reduction in the amounts of Ndff and Ndfs as the result of added E. angustifolia leaves (GM) is useful for maintaining soil fertility and substituting considerable amounts of the costly and environmentally pollutant inorganic N-fertilizer, particularly at early growth stages of sorghum [22,38].…”

“…It could also be noticed that (GM) addition induced similarity in the amounts of (NY) in either (2F:1S +GM) and (F -GM) or (1F:2S -GM) and (S +GM). These results indicated a positive impact for the use of (GM) to enhance plant growth through providing a portion of its nitrogen demands, alleviating the adverse effect of salinity on (NY) [25,36,37], and increasing the available soil mineral nitrogen content [22,38].…”

Approximately, the same range of %NUEgm values (20-52%) has been reported for sorghum manured with sesbania leaves grown in saline soil [13,25]. The reduction in %NUEgm could be attributed to the increase in soil salinity ( Table 2), as salinity has a negative effect on green manure use efficiency.…”

Background:A pot experiment was conducted to determine the effects of alternate irrigation with saline (S) and fresh (F) water on growth, nitrogen uptake and nitrogen use efficiency in Sorghum crop (Sorghum bicolor L.) manured with Elaeagnus angustifolia leaves (GM) using 15 N. Method:Five types of irrigation systems abbreviated as (F, 2F:1S, 1F:1S, 1F:2S and S) and one rate of Green Manure (GM) were employed. Result:Results showed reductions in both Dry Matter yield (DM) and nitrogen uptake (NY) in sorghum grown under different types of irrigation systems as compared with the control (F). The reduction rates of these two parameters increased with increasing number of irrigations with saline water. However, E. angustifolia leaves applied as green manure mitigated the harmful effect of salinity on plant growth parameters. The percent increments as a result of GM application were 9, 19, 43, 43 and 65% for DM, and 33, 30, 42, 36 and 60% for NY in F, 2F:1S, 1F:1S, 1F:2S and S, respectively. Nitrogen use efficiency of added green manure ranged between 25 and 47% in the different types of irrigation systems. Our results indicated that increment of NY in green manured sorghum plants was mainly attributed to its nitrogen availability. According to the availability of S and F water resources, and the economic returns aimed by farmers in the semi-arid regions, it is recommended to use (2F:1S, 1F:1S and 1F:2S) in combination with E. angustifolia leaf GM. Such a procedure can be considered as a promising agricultural practice to improve yield with a proper water resource investment.

In the near future, composted bio-solids are expected to play a major role in agriculture. In order to evaluate their contribution to plant growth and nutrition, a mixed sorghum-poultry manure compost was prepared using 15 N-labeled materials. Four treatments were compared in a pot trial: fertilized with compost vs. unfertilized, both of them combined with (cultivated) and without (bare) plants of fibre sorghum (Sorghum bicolor [L.] Moench.). Soil mineral nitrogen (N-min), plant growth, and N uptake were monitored over a whole growing season (167 d after fertilizer treatment; DAT). Apparent soil mineralization (ASM) and apparent recovery fraction of nitrogen by the plant (ARF) were assessed, as well as the 15 N recovery fraction by the plant ( 15 NRF). Compost enhanced sorghum biomass at mid growth (+ 200% of dry weight compared to the unfertilized). However, the difference between the control and the fertilized plants progressively decreased towards the end of the season (+ 70%). Fertilized and unfertilized plants followed different growth patterns over time, although of the same sigmoid type. Conversely, N concentration in plant tissues followed a common dilution curve, indicating that fertilized sorghum efficiently used the supplied N, avoiding luxury consumption. Apparent soil mineralization approximately reached 45% of compost total N in pots without plants. Apparent recovery fraction attained 100% at about two third of the growing season (DAT 111), then declined to about 50% because of root and leaf decline. Compared to it, 15 NRF only reached ≈ 20% at mid growth (DAT 83), then declined to 12%. Despite the large difference in absolute values, ARF and 15 NRF exhibited a significant correlation, indicating a common trend in time. In contrast to 15 NRF, the amount of nutrient derived from fertilizer (Ndff) taken up by the plant decreased over the growth season, proving that compost contributed more to plant nutrition in the early (Ndff ≈ 50%) than in the late growing season (Ndff ≈ 25%). The large difference between ARF and 15 NRF suggests that sorghum exerted a strong nutrient demand on the soil and on the fertilizer. Both 15 NRF and ARF are considered valuable traits: the former better describes fertilizer behavior and actual supply of N, while the latter outlines the overall effect of fertilizer application on crop nutrition.

The nutritive value of Sesbania aculeate harvested after 60 and 120 days of planting and subjected to two cutting regimen (15 or 30 cm length) was evaluated by determination of the crude protein (CP), crude fibre (CF), buffer soluble nitrogen (BS-N), buffer soluble non-protein nitrogen (BS-NPN) and cell wall constituents (neutral-detergent fibre; NDF, acid-detergent fibre; ADF and lignin). In vitro digestible organic matter (IVDOM), metabolizable energy (ME), microbial nitrogen (MN) and biomass (MBM) production were also estimated in the experimental plant samples after their incubation with rumen fluid for 96 h in the absence or presence of polyethylene glycol (PEG, 6000) at a ratio of 2:1 PEG:substrate. Fermentation characteristics (initial gas production; a, gas production during incubation; b, potential gas production; a+b, fractional rate of gas production; c) were assessed using an in vitro incubation technique with rumen fluid. There was a significant (P < 0.05) effect of harvest time on all studied nutritive parameters and fermentation characteristics. The early harvest plant samples (after 60 days of planting) gave significantly higher values of IVOMD, ME, CP, BS-N, BS-NPN, MN, MBM and fractional rate of gas production and lower values of CF and cell wall constituents than the late harvest. Crude protein, BS-N, BS-NBN, IVOMD and ME were negatively correlated with CF and cell wall constituents. Metabolisable energy and IVOMD were positively correlated with CP, BS-N and BS-NPN. Cutting treatments significantly affected the CP, CF, BS-N, BS-NPN, NDF, ADF, IVDOM, ME, potential gas production and b values. There was no significant (P > 0.05) effect of added PEG on IVDOM, ME, MN, MBM, fermentation characteristics and gas production over 96 h. The greatest proportion of gas production occurred between 6 and 24 h of incubation. The fractional rate of gas production from 100 mg substrate was higher (0.046 mL/h) for the plant samples harvested at early stage and cut at 30 cm length than harvested at late stage (0.018 mL/h). C values were negatively correlated with lignin concentrations. The amount of MN and MBM produced from 100 mg substrate amounted to 1.29 mg and 14.95 mg at early maturity stage and 0.68 mg and 7.89 mg at late stage, respectively. Microbial nitrogen and MBM production were negatively correlated with CF, cell wall constituents and gas production but positively correlated with CP, BS-N and BS-NPN.
