Effect of row spacing on nitrogen uptake, nitrogen utilization and yield of summer maize Effects of nitrogen rate and row spacing on winter wheat grain quality Effects of Nitrogen Rate and Row Spacing on Grain Yield and Physiological Characteristics of Winter Wheat Effects of Different Row Spaces on Canopy Structure and Resistance of Summer Maize Effect of Row Spacing and Seeding Rate on Seed Yield and Yield Components of Bromus inermis Leyss. Effects of nitrogen application and row spacing on canopy structure and yield of fresh waxy maize Effects of narrow row spacing and uniform sowing on canopy environment,individual plant traits, and biomass production in late-sowing winter wheat Influences of row spacing on fertile tillers and characters of seed yield of Elymus sibiricus cv. Chuancao No.2 Photosynthetic Dynamic Variation of Switchgrass under Different Row Spacing in Loess Hilly gully Region EFFECTS OF ROW SPACING IN WINTER WHEAT ON CANOPY STRUCTURE AND MICROCLIMATE IN LATER GROWTH STAGE Effect of Row Spacing and Sowing Rate on the Growth and Seed Yield of White Clover Effects of row spacing and seeding rate on radiation use efficiency and grain yield of wheat Effects of fertilization and row spacing on microenvironment within population canopy and dry matter accumulation of waxy maize Effects of different combinations of planting density, row spacing and row direction on field microclimatic conditions and grain yield of maize Effect of maize row spacing on yield of pea/maize intercropping system Relationship between Row Spacing,Irrigation Rate and Growth Redundancy in Alfalfa Population Effect of Planting Row Distance and Nitrogen Rate on Switchgrass Yield and the Content of Crude Protein Property of root distribution of triploid Populus tomentosa and its relation to root water uptake under the wide-and-narrow row spacing scheme Root biomass distribution of triploid Populus tomentosa under wide- and narrow-row spacing planting schemes and its responses to soil nutrients Effects of Planting Density and Row Spacing on Canopy Apparent Photosynthesis of High-Yield Summer Corn Optimization of Plant Density and Row Spacing for Mechanical Harvest in Winter Rapeseed (Brassica napus L.)
