Sorghum Research Paper-22
Overall, sorghum yield improvement seemed to be primarily achieved by gains under environmental stress and low yielding environments rather than by modifications or improvements on maximum yield potential (Assefa and Staggenborg, 2010). doi: 10.2134/agronj1973.00021962006500050009x Cross Ref Full Text | Google Scholar Stickler, F. Sorghum is a C4 (Kranz leaf anatomy) erect plant constituted from a main stem, leaf canopy, head, and tiller organs. Sorghum growth and nutrient uptake in relation to soil fertility: I.

The final tiller number is dependent on the genotype, temperature, and nutrient resources. Dry matter accumulation patterns, yield, and N content of grain.

Final plant size as related to the aboveground portion is dependent on the plant response to photoperiod sensitivity and growing conditions; while the belowground section is composed by extensive fibrous root systems. doi: 10.2135/cropsci20 Cross Ref Full Text | Google Scholar Roy, R.

Superior water use efficiency for grain sorghum as relative to other crops (such as corn and soybean), expressed as higher yield per unit of water, was documented in low-yielding, and water-limited environments (Stone et al., 2006).

Historically, sorghum genetic improvement is related to changes in aboveground biomass production (increased leaf to stem ratio and higher leaf mass), longer panicle length, decrease in peduncle length, and superior root mass (Assefa and Staggenborg, 2011). doi: 10.1016/S0378-4290(98)00143-9 Cross Ref Full Text | Google Scholar Rajewski, J.

Unraveling the complexity underpinning nitrogen (N) use efficiency (NUE) can be physiologically approached via examining grain N sources and N internal efficiency (NIE) (yield to plant N content ratio).

For the main stem, leaf area increases until full expansion of the flag leaf occurs; a waxy bloom often covered leaf sheath and stem organs. Changes in area, yield gains, and yield stability of sorghum in major sorghum-producing countries, 1970 to 2009.

Grains are developed in the head organ (in the uppermost section of the plant) after flowering time.

Moench) improvement has been related to targeted modifications in genotype (G component) and management practices (M component), such as (a) fertilization rates, (b) irrigation, and (c) tillage practices (Eghball and Power, 1995; Duvick, 1999; Assefa and Staggenborg, 2010).

A long-term study conducted in Texas (1939–1997) documented yield improvements were mainly related to the introduction of new sorghum hybrids, water conditions at planting, better weed (herbicide) control and conservation practices such as zero tillage (Unger and Baumhardt, 1999). doi: 10.2134/agronj1965.00021962005700060015x Cross Ref Full Text | Google Scholar Stone, L.
