Irrigation associated to reduction on planting spaces between rows and between coffee plants has been a featured practice in coffee cultivation. The objective of the present study was to assess, over a period of five consecutive years, influence of different irrigation management regimes and planting densities on growth and bean yield of Coffea arabica L.. The treatments consisted of four irrigation regimes: climatologic water balance, irrigation when the soil water tension reached values close to 20 and 60 kPa; and a control that was not irrigated. The treatments were distributed randomly in five planting densities: 2,500, 3,333, 5,000, 10,000 and 20,000 plants ha-1. A split-plot in randomized block design was used with four replications. Irrigation promoted better growth of coffee plants and increased yield that varied in function of the plant density per area. For densities from 10,000 to 20,000 plants ha-1, regardless of the used irrigation management, mean yield increases were over 49.6% compared to the non-irrigated crop.

Effect On Growth

"A field experiment was carried in two locations (Nasr and Eslah) in Thi Qar province during winter season (2015 – 2016). the experience included study two factors which of three concentrations of iron chelated (0-50-100 mg L-1 ) spray on leaves before flowering period , and three levels of potassium fertilizer ( 0- 50-100 K2O kg h-1 ) The experiment was designed by using randomized complete blocks design with three replication (RCBD) with three replications. Results showed that the iron chelated treatments had a significant effect on growth traits in both of Nasr and Eslah locations , the treatment of concentration of 100 mg/ L get higher values for growth traits plant height 88-85 cm and the number of tillers / plant 12-10 Tillers, area flag leaf 25.6-25.5 cm2 and yield grain 6.04-5.97 t / h in Nasr and Eslah, respectively, while potassium treatment had a significant effect on growth traits in both of locations, the treatment 100 kg K2O h -1 gave higher values for growth traits area flag leaf reached 28-27.1 cm2 and gave the highest values of the attributes of yield the components and yield grain 6.00-5.9 t / h in Nasr site and Eslah, respectively . The combination treatment (100 mg Fe with 100 kg K2O) gave the highest mean properties of the yield components, number of spikes, number of grains per spike, and grain yield compared to the control treatment"

Effect On Growth

1. Treatment of seed beans with an organomercurial dressing has been shown to have little or no effect on growth and yield.2. Experiments have shown that the emergence of ‘weevilled’ beans is markedly less than that of sound beans for both winter and spring sowings.3. It is suggested that the reduced emergence of weevilled beans is due to beetle injury of the seed and not to invasion by soil organisms.
