Dry matter accumulation and crop growth rate of maize population under different treatments.
The curves of crop growth rate (CGR) of the common bean plants of the cultivar BRS-Estilo as a function of N application forms (Figure 3A) and rates (Figure 3B) indicate a relationship between CGR with TDM and LAI.
Data recording: The leaf area index (LAI), crop growth rate (CGR) and net assimilations rate (NAR) were determined by standard procedures Watson (1947) and Hunt (1978) post 30, 60 and 90 days after sowing and the later on the average was calculated.
Crop growth rate (CGR) and net assimilatory rate (NAR) was also higher with same level of nitrogen application (Table 1).
Different tillage practices used had significant effect on leaf area index (LAI) and crop growth rate (CGR) of wheat during the whole growth period (Fig.
It seems like that in this experiment nitrogen has affected the number of grains per corn by increasing crop growth rate. Moreover, nitrogen caused assimilate availability for the corn through photosynthesis durability and thus because of the decrease of grains competition for taking nutrients the number of grains per corn and the weight of 1000-grain increased.
1a).The relationship of LAI with crop growth rate (CGR) and leaf area duration (LAD) was found to be highly significant.
Crop Growth Rate (CGR), expressed in grams per [m.sup.2] of ground per day, is a physiological variable that indicates the quantity of phytomass accumulated per unit of area under cultivation during a period of time.
The data regarding the crop growth rate as influenced by irrigation and nitrogen levels presented in figures 1 and 2.
Previous relationships between photosynthesis and pod and seed number were frequently based on static relationships (e.g., average plant or crop growth rates during flowering and pod set; Pandy et al., 1984; Egli and Zhen-wen, 1991; Vega et al., 2001).
At 4, 8 and 12 WAS, crop growth rate (CGR) was calculated using the following equation
