“…In the present study, we found that there was a higher yield response at low N rates than that at high N rates under the SW rotation. This is consistent with experimental results from Pakistan; Shah et al (2003) reported that mungbean residue retention increased the grain yield and biomass of winter wheat, by 19-83% (average 43%) and 14-73% (average 45%) at 0 kg N ha −1 , and by only 2% and 1% at 150 kg N ha −1 over three experimental years. Similar results have also been reported for other cereal crops.…”

a b s t r a c tDryland wheat is the major contributor to wheat production in the world, where water deficiency and poor soil fertility are key factors limiting wheat grain yields and nutrient concentrations. A field experiment was carried out from June 2008 to June 2011 at Shilipu (latitude 35.12 • N, longitude 107.45• E and altitude 1200 m above sea level) on the Loess Plateau (a typical dryland) in China, to investigate the effects of rotation with soybean (Glycine max) green manure (GM) on grain yield, total N and total Zn concentrations in subsequent wheat (Triticum aestivum L.), and on nitrate-N and available Zn in the soil. The benefits of crop rotation with soybean GM on wheat grain yields became more evident with time. In the second and third years, the grain yields of wheat rotated with soybean GM reached 4871 and 5089 kg ha −1 at the 108 kg N ha −1 rate. These yields were 21% and 12% higher than the highest yields of wheat under a fallow-winter wheat (FW) rotation. Rotation with soybean GM reduced the amount of N fertilizer required to obtain wheat grain yields and biomass levels similar to wheat grown in the FW rotation by 20-33%. In the first 2 years, average grain N concentrations over all N rates increased by 6% and 12%, and those of Zn increased by 26% and 14% under the soybean GM-winter wheat (SW) rotation, compared with the FW rotation. The increased grain N and Zn concentrations were found to be related to the increased concentrations of nitrate-N and available Zn in the soil, particularly at the sowing of winter wheat. However, grain N and Zn concentrations were not improved by rotation with soybean GM in the third year. This was attributed to the dilution effect caused by the more grain yield increase than its nutrient export. In conclusion, planting soybean for GM in fallow fields reduced the need for N fertilizer to enhance wheat yields in this dryland region. Change in wheat grain N and Zn concentrations was related to soil nutrient concentrations, and to the balance between increased grain yield and its nutrient export.

“…Several studies have shown that legumes can increase the yield of a subsequent crop, in particular when no fertilizer N is applied (Heenan 1995;Kumar and Goh 2002;Shah et al 2003;Mayer et al 2003;Jensen et al 2004). In the present experiment, oat biomass production was greater was applied to the second crop in the rotation.…”

We investigated conservation and cycling of N under oat-oat and lupine-oat rotations in disturbed and undisturbed soil, when roots or roots plus aboveground residues were retained. Crop residues were labelled with 15 N in Year 1, and differential soil disturbance was imposed after harvest. In Year 2, plant growth, N transfer from residue into the various sinks of the second crop (plant, soil, and residual residues), and changes in microbial activity and numbers were determined. Oat biomass was greater after lupine than after oat due to differences in supply of N from these residues. Buried residues of both crops appeared to decompose faster than when left on the soil surface. Lupine residues decomposed faster than oat residues. Oat biomass was not affected by soil disturbance if grown after lupine but decreased when oat straw was buried in the soil. More residue N was recovered from soil than from the crop. for oat and 61-63 kg N ha −1 for lupine relative to treatments where they were removed. Over a year, lupine contributed 9 to 20 kg N ha −1 more to the agroecosystem than did oat.

“…Nitrogen is vital in crop productivity which plays role in accelerating yield and gave optimum economic return [3] and its deficiency will constitutes in low yield and productivity in cereal crops [4]. Efficient nitrogen use by maize permits use of appropriate source in an adequate amount, at proper timing and suitable application rates [5,6].…”

. Effect of nitrogen rates and application times on growth and yield of maize (Zea mays L. Abstract A field experiment was designed to study the effect of nitrogen rates and application time on growth and yield of maize at Agronomy Research Farm, The University of Agriculture, Peshawar during summer 2014. An experiment was laid out in randomized complete block design using three replications. Four nitrogen rates (80, 120, 160 and 200 kg ha -1 ) were applied as full at sowing ( AT1), ½ at sowing + ½ at 25 days after sowing (AT2) and 1/3 at sowing + 1/3 at 25 days after sowing + 1/3 at 50 days after sowing (AT3). Results showed that all studied parameters were significantly affected by N-levels. Maximum mean leaf area (258.19 cm 2 ), plant height (188 cm), grains ear -1 (369), 1000-grains weight (245 g), biological yield (9593 kg ha -1 ), grain yield (4109 kg ha -1 ) and harvest index (42 %) were observed with application of 160 kg N ha -1 . The results further revealed that maximum mean leaf area (260 cm 2 ), plant height (184 cm), grains ear -1 (380), biological yield (9195 kg ha -1 ), 1000-grains weight (247 g) and grain yield (3707 kg ha -1 ) were recorded when N was applied ½ at sowing + ½ at 25 days after sowing. The interactive effect of N rates and application time was found significant for mean leaf area. It was concluded that nitrogen at the rate of 160 kg ha -1 and application of N ½ at sowing + ½ at 25 days after sowing is most reliable for yield and production of maize crop in the study region and thus optional for general use in agriculture.
