“…It is generally accepted that yield increases when Finger millet rows are narrowly spaced. This, however, is not always supported by the literature (Crabtree and Rupp, 1980;Teich et al, 1993;McLeod et al, 1996;Lafond and Gan, 1999;Hiltbrunner et al, 2004). Intercropping has gained interest because of potential advantages it offers over yielding, i.e.…”

The land use efficiency and weed suppression through intercropping plays a pivotal role. A field experiment was carried out on finger millet (Eleusine indica L. Gaertn) -horsegram (Macrotyloma uniflorum (Lam.) Verdc.) mono-and intercropping with various weeding (0, 1, or 2 hand-weeding operations) and row spacing (20 and 30 cm) treatments in the Bastar plateau region of India over consecutive five Kharif seasons (2010/2014). The experimental design was a randomized complete block with eighteen treatments replicated thrice. Five percent significant differences were observed in yield and its economics with and without weeding treatments. Horsegram yield was significantly reduced by Finger millet when intercropped. However, total productivity and land use efficiency were higher under the intercropping system as compared to monocrops of either species. There was a significant reduction in weed density and biomass for the intercropping system over both monocrops. Finger millet facilitated an increase in nodule number and dry weight in horsegram under intercropping over monocrops, moreover, root length of horsegram was greater when intercropped. These findings suggest that intercropping Finger millet and horsegram increase total productivity per unit area improve land use efficiency and suppress weeds. Focussing the experimental findings, Finger millet-horsegram (30 cm) with two weedings may be recommended for yield advantage, higher net income, more efficient utilization of resources, and weed suppression as a biological control in western plateau region of India.

“…Bavec et al (2002) and Geleta et al (2002) reported that protein content of grain decreased with increasing seeding rate. In contrast, Campbell et al (1991) and McLeod et al (1996) reported that protein content of grain was not infl uenced by seeding rate. In the present study, grain protein content was similar at 50 and 150 seeds m -2 (Table 2).…”

Abbreviations : LAI, leaf area index; SPAD, chlorophyll meter; 0-0N, 0 and 0 g N m -2 applied at active tillering and jointing, respectively; 4-2N, 4 and 2 g N m -2 applied at active tillering and jointing, respectively Abstract : We examined the effects of seeding rate, 50 or 150 seeds m -2 , nitrogen (N) application rate at active tillering and jointing, 4 and 2 g N m -2 , respectively, or none, and N application rate at anthesis, 0, 2, 4, or 6 g N m -2 , on grain yield and protein content of a bread wheat cultivar, 'Minaminokaori', during the 2004-2005 crop season in southwestern Japan. Grain yield was similar at a seeding rate of 50 and 150 seeds m -2 . It was higher when 4 and 2 g N m -2 were applied at active tillering and jointing, respectively (4-2N), than when no N was applied at these stages (0-0N). However, it was not infl uenced by N application rate at anthesis. Grain protein content was similar at 50 and 150 seeds m -2 . It was higher in 4-2N than in 0-0N. It was the highest when 6 g N m -2 was applied at anthesis, followed by 4, 2, and 0 g N m -2 . The SPAD value at anthesis was higher at 50 than 150 seeds m -2 , but leaf area index (LAI) at anthesis was similar at 50 and 150 seeds m -2 and protein content of grain was nearly the same at 50 and 150 seeds m -2 irrespective of N application rate at anthesis. LAI and the SPAD value were higher in 4-2N than in 0-0N and the protein content of grain was also higher in 4-2N than in 0-0N irrespective of N application rate at anthesis. Therefore, both LAI and the SPAD value may be important traits related to the N application rate at anthesis suitable for yielding wheat grain with a high protein content.

“…Seeding density affects grain yields and plant density (McLeod et al, 1995). In addition, high seeding density can result in higher grain yields and plant density than low seeding density .…”

“…Stougaard and Xue (2003) found that high seeding density increased yield 12%-18% when compared with low seeding density in Montana. Work in Canada showed that a 60 kg ha −1 seeding rate resulted in a 61% higher plant density than a 30 kg ha −1 seeding rate (McLeod et al, 1995). High seeding density can control weed biomass and reestablishment of weeds in ensuing seasons and can compensate for poor plant establishment (Rurnett et al, 2003).…”

The components that define cereal-grain yield potential have not been well defined. The objective of this study was to collect many differing biological measurements from a long-term winter wheat (Triticum aestivum L.) study in an attempt to better define yield potential. Four treatments were sampled that annually received 0, 45, 90, and 135 kg N ha −1 at fixed rates of phosphorus (P) (30 kg ha −1 ) and potassium (K) (37 kg ha −1 ). Mid-season measurements of leaf color, chlorophyll, normalized difference vegetative index (NDVI), plant height, canopy temperature, tiller density, plant density, soil moisture, soil NH 4 -N, NO 3 -N, organic carbon (C), total nitrogen (N), pH, and N mineralization potential were collected. In addition, soil texture and bulk density were determined to characterize each plot. Correlations and multiple linear-regression analyses were used to determine those variables that can predict final winter wheat grain yield. Both the correlation and regression analyses suggested mid-season NDVI, chlorophyll content, plant height, and total N uptake to be good predictors of final winter wheat grain yield. Keywords
