Mild moisture stress causes sucrose to be deposited preferentially in sugarcane stalks so that sucrose yields may be improved. The rule of thumb in the industry states that a crop should be dried off for the time it would take pan evaporation to equal twice the plant available water holding capacity of the soil in which the crop is rooted (or twice TAM). Despite this useful rule farmers often d...

Problem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and 2010 to evaluate t...

Our previous research, conducted under well-watered conditions without fertilizer application, showed that fuzziness cottonseed trait resulted in cottonseed nutrition differences between fuzzy (F) and fuzzless (N) cottonseed. Under water stress conditions, B mobility is further limited, inhibiting B movement within the plant, affecting seed nutrition (quality). Therefore, we hypothesized that b...

Crassulacean acid metabolism (CAM) occurs in many Euphorbiaceae, particularly Euphorbia, a genus with C3 and C4 species as well. With the aim of contributing to our knowledge of the evolution of CAM in this genus, this study examined the possible occurrence of CAM in Euphorbia milii, a species with leaf succulence and drought tolerance suggestive of this carbon fixation pathway. Leaf anatomy co...

some of the morpho-physiological characteristics related to the leaf growth and development of phaseolus vulgaris l. genotypes have been studied in the field conditions at the seed and plant improvement institute (spii). the study was performed as split plot experiment in a randomized complete block design with four replications in well-watered and water deficit conditions with eight genotypes ...

Drought stress and nutrient deficiency are two main factors that restrict the growth yield of peanut (Arachis hypogaea L.) in arid semi-arid regions. However, effects N fertilizer on root pod under different water conditions unclear. The growth, morphology, were studied combinations. Two soil treatments tested: Well-watered (WW, 80%-85% field capacity) drought (DS, 55%-60% capacity). Three no a...

The application of soil mulching is widely used to improve crop productivity within semiarid regions Mediterranean environments. A field study was conducted during two consecutive cycles spearmint (Mentha spicata L.) the rainfed region Southern Italy evaluate effects straw mulch cultivation practices on yields and ecophysiological activities. Four treatments were evaluated: (1) with (RM), (2) w...

In the sub-tropics, water and nitrogen are the most important factors limiting the grain yield of maize. The effect of nitrogen (N) rates and drought stress at different growth stages of maize were investigated. Nitrogen treatments consisted of 100, 150, and 200  kgN.ha-1 from the urea source while water stress treatments were composed of irrigation-off since the early 10-leaf stage to emergenc...

The water-limited potential yield of wheat (Triticum aestivum L.) may be largely dependent on plant transpiration behavior. Research into dynamics is limited due to the difficulty monitoring water use over an extended period time. advent fully automated gravimetric platforms makes this research possible. methods for using equipment study in water-deficit environments are not well established. o...
