“…With respect to WUE, our findings are consistent with those of other authors who have shown that in tolerant plants or conditions of below-lethal drought stress, there are improvements in WUE either as a result of better stomatal control or of reduced plant vigor [32,33,34]. Where irrigation improves WUE, further gains can only be maintained by irrigation suppression, as has been shown for cotton [35]. Hence suppression of vigor can be expected in water stressed plants, while over-irrigation also suppresses plant growth, probably a result of reduced roots respiration.…”

With changing rainfall patterns, deforestation and degradation of arable land, freshwater resources for irrigation are reducing, increasing the potential for drought stress on crops. The aim of this research was to study the growth and ecophysiological responses of beans, pepper, tomato and watermelon potted and grown in screenhouse under varied irrigation, for 14 days. There were three treatments: zero irrigation after seedling establishment, 0.1 L/pot/week, 0.2 L/pot/week and 0.3 L/pot/week respectively, each pot with three plants, in a completely randomized design with 3 replicates. Growth and ecophysiological measurements were recorded for the first three weeks of growth. ANOVA and Pearson Correlation were conducted, with significance at α 0.05. Plants with zero irrigation had the least growth in all parameters measured; growth was stimulated by irrigation, with a threshold at 0.2 L/week (corresponding to 2200 mm, the mean annual rainfall for the region) for pepper, tomato and watermelon seedlings. Biomass accumulation in all species increased with irrigation but WUE decreased. The quantum efficiency of photosystem II photochemistry of beans and watermelon increased to 0.8 as irrigation increased, while pepper and tomato remained low in all treatments, indicating stress. These results show that early seedling stages are sensitive to drought; however, beans and watermelon seedlings were more resistant to soil moisture deficit than tomato and pepper seedlings. Early farm management should consider appropriate irrigation volumes for better and more vigorous crops in the field. This is essential in a future where irrigation water deficits are predicted to increase during the cropping seasons.

“…Water stress intensities caused by different cotton irrigation frequencies presented similar results for this variable (SILVA et al, 2010). The decline of this variable with the heightening of soil water stress was similar to what was observed by Pereira Filho et al (2011), when analyzing the effects on castor bean culture of different soil water stress intensities.…”

“…The use of irrigated agriculture requires the knowledge of determining factors of irrigation management that directly interfere in greater or lesser consumption of water, soil humidity storage (SILVA et al, 2010), knowledge of the water requirements of the crops (CORREIA; and physiological aspects (TAIZ; ZEIGER, 2009), which makes irrigation a practice that can not only increase productivity, but can also provide a product with better quality (PIRES et al, 2009). …”

-This study was conducted to evaluate the effect of different irrigation frequencies on growth, gas exchange and yield of the peanut (Arachis ypogea L). The experiment was conducted in the field using the experimental design of randomized blocks with five treatments, five replications with four plants per plot. The treatments were composed: F2 = (irrigation every 2 days), F4 = (irrigation every 4 days), F6 = (irrigation every 6 days), F8 = (irrigation every 2 days) and F10 = (irrigation every 10 days). At 60 days after sowing (DAS), the gas exchange variables (photosynthesis, stomatal conductance and transpiration) and growth variables (plant height, leaf number, stem diameter and shoot dry matter) were evaluated. The highest irrigation frequency tested (every two days) promoted the best results for plant growth (leaf number, plant height, shoot dry matter) e for leaf gas exchange. The highest yield of field grown peanuts at the conditions prevailing in Fortaleza, Ceará, is associated with the adoption of an irrigation frequency interval of two days.Key words: Arachis ypogea L.. Growth. Agricultural Irrigation.RESUMO -Realizou-se esse trabalho com o objetivo de avaliar o efeito de diferentes frequências de irrigação sobre o crescimento, trocas gasosas e produtividade da cultura do amendoim (Arachis ypogea L). O experimento foi desenvolvido no campo e obedeceu ao delineamento experimental de blocos ao acaso, com cinco tratamentos e cinco repetições. Os tratamentos empregados foram: F2 = (irrigado a cada dois dias), F4 = (irrigado a cada quatro dias), F6 = (irrigado a cada seis dias), F8 = (irrigado a cada dois dias) e F10 = (irrigado a cada dois dias). Aos 60 dias após a semeadura (DAS), realizaram-se medições de trocas gasosas (fotossíntese, condutância estomática e transpiração) e análise de crescimento (altura de planta, número de folhas, diâmetro do caule e matéria seca da parte aérea). Para as variáveis produtivas as plantas foram colhidas aos 90 DAS e analisadas as seguintes variáveis: número de frutos por plantas, peso de vagem, tamanho de vagem, peso de 100 sementes e produtividade. A maior frequência de irrigação testada (a cada dois dias) promoveu os melhores resultados para o crescimento de planta (número de folhas, altura da planta, matéria seca) e para trocas gasosas. A maior produtividade de amendoim cultivado em campo, nas condições de Fortaleza -Ceará está associada à adoção de uma frequência de irrigação com intervalo de dois dias.

“…However, under severe drought, value of HI decreased as compared to mild drought. Drought applied at different growth stages of cotton decreased HI and highest reduction was observed when drought was imposed at flowering stage (Silva et al, 2010). Physiological Parameters: The water deficit stress adversely affects a number of physiological processes in plants; disturbs stomatal conductance, rate of transpiration, pigment content of leaves, rate of photosynthesis, ATP content (Lawlor and Cornic, 2002), causes inhibition of enzymatic activities (Ashraf et al, 1995); ionic imbalance and disturbances in solute accumulation (Khan et al, 1999).…”

Water scarcity is the most serious abiotic stress restricting plant productivity throughout the world. Losses in crop yield due to drought exceed from losses caused by other environmental factors. In this review article different morphological, physiological and yield attributes of cotton under drought stress, mechanism of drought induced losses and various management strategies to mitigate drought stress have been discussed. Drought stress reduces growth of leaf, stem and root, interferes with leaf water relations, photosynthesis, respiration, reduces water-use efficiency and ultimately yield of cotton. Under water deficit conditions cotton shows various responses to cope with drought stress. The major mechanisms include accumulation of osmoregulators, plant growth regulators and production of heat shock proteins. Different management strategies to alleviate water deficit stress like foliar application of osmolytes, potassium and growth regulators (hormones), various drought responsive genes, proteins at molecular level, screening and breeding programs against drought tolerance and mulching are also discussed in this paper.
