“…In other simulations with chickpea, a rapid root growth rate was shown to decrease yield by an average of 5%, whereas an increase in the depth of root water extraction by 20 cm increased yield by an average of 10%, therefore, among all the genetic traits tested, this trait conferred the largest yield benefit . We note that this study also modelled the effect of management options and showed that a 40% yield improvement was derived from providing a 30 mm irrigation at the beginning of seed growth, which is in full agreement with previous results (Soltani et al 2001). Therefore, these data show the efficacy of a model for comparing both genetic and management options.…”

“…It is indeed quite clear that leaf development is under hydraulic control (Munns and Cramer 1996;Tardieu et al 2010;Pantin et al 2012). Leaf development is also sensitive to soil drying, and the termination of leaf growth occurs before termination of transpiration (Sadras and Milroy 1996;Soltani et al 2001;Reymond et al 2003;Parent et al 2009;Tardieu et al 2010). Depending on the water stress scenario, limiting leaf development under water stress could limit productivity.…”

Abstract. Water deficit is the main yield-limiting factor across the Asian and African semiarid tropics and a basic consideration when developing crop cultivars for water-limited conditions is to ensure that crop water demand matches season water supply. Conventional breeding has contributed to the development of varieties that are better adapted to water stress, such as early maturing cultivars that match water supply and demand and then escape terminal water stress. However, an optimisation of this match is possible. Also, further progress in breeding varieties that cope with water stress is hampered by the typically large genotype Â environment interactions in most field studies. Therefore, a more comprehensive approach is required to revitalise the development of materials that are adapted to water stress. In the past two decades, transgenic and candidate gene approaches have been proposed for improving crop productivity under water stress, but have had limited real success. The major drawback of these approaches has been their failure to consider realistic water limitations and their link to yield when designing biotechnological experiments. Although the genes are many, the plant traits contributing to crop adaptation to water limitation are few and revolve around the critical need to match water supply and demand. We focus here on the genetic aspects of this, although we acknowledge that crop management options also have a role to play. These traits are related in part to increased, better or more conservative uses of soil water. However, the traits themselves are highly dynamic during crop development: they interact with each other and with the environment. Hence, success in breeding cultivars that are more resilient under water stress requires an understanding of plant traits affecting yield under water deficit as well as an understanding of their mutual and environmental interactions. Given that the phenotypic evaluation of germplasm/breeding material is limited by the number of locations and years of testing, crop simulation modelling then becomes a powerful tool for navigating the complexity of biological systems, for predicting the effects on yield and for determining the probability of success of specific traits or trait combinations across water stress scenarios.

“…Saxena (1980) reported that using supplemental irrigation in order to resolve stress at critical stages of plant growth had significant effect on grain yield increase. Soltani et al (2001) reported that using supplemental irrigation to free the crops from soil moisture stress at critical growth and development stages, would increase chickpea grain yield. It appears that water defect at chickpea generative stages prevents yield potential attainment through flowers and pods shedding (Nayyar et al, 2006).…”

“…Even though the chickpea is considered a drought tolerant crop, its seed yield can increase also with a supplementary irrigation, applied between flowering and beginning seed growth, mainly in environments and years with very low amounts of rainfall during the reproductive stage (Soltani et al, 2001;Abbate et al, 1994;Milia, 1993;Lombardo et al, 1993;Gristina et al, 1993).

Chickpea is one of the important winter legumes in Nepal. It is grown after rice or maize either as sole or mixed crop. In Nepal, chickpea is mostly grown as rainfed crop on residual soil moisture or sometimes under irrigation. Lack of irrigation results drought and heat stress which affects crop growth and development. Irrigation at proper time is one of the most important factors for achieving higher crop yield. The experiment regarding use of supplementary irrigation time on chickpea was carried out at Regional Agricultural Research Station, Khajura, Banke, Nepal during the winter season of the year 2011 and 2012. The experiment was laid out in Randomized Complete Block Design with three replications. Seven different time intervals of irrigation was applied in the experiment for both years. Treatments differed significantly in terms of grain yield but showed non -significant difference in days to flowering and maturity over the years. The combined analysis of the experiments showed that the highest grain yield (2318 kg/ha) was produced when irrigation was supplied at vegetative stage followed by irrigation supplied at flowering stage (2298 kg/ha) and pod fill stage (2104 kg/ha) respectively.Int J Appl Sci Biotechnol, Vol 3(3): 431-433

This research was carried out in 2014 at the Research Farm of the University of Tabriz, Iran. The experiment was arranged as split plot on the basis of randomized complete block with three replicates to assess the effects of four irrigation intervals (irrigations after 60, 80, 100 and 120 mm evaporation) on physiological and agronomical traits of three cultivars of maize (Zea mays L.; 'SC704', 'NS640', 'DC303': late, mid and early maturing, respectively). Irrigation intervals and maize cultivars were assigned to the main and sub-plots, respectively. Leaf temperature of all maize cultivars significantly increased, but chlorophyll content index, maximum efficiency of photosystem II, number of grains per plant, 1000 grain mass, plant biomass, grain yield and harvest index significantly decreased with increasing irrigation intervals. Late maturing cultivar ('SC704') was superior in all studied traits, followed by mid ('NS640') and early ('DC303') maturing cultivars. It was concluded that water limitation can potentially reduce performance of maize cultivars in the field, but the extent of this reduction depends on genotype and severity of stress.Key words: chlorophyll content; leaf temperature; maize; photosystem II; drought stress IZVLEČEK USPEVANJE SORT KORUZE (Zea mays L.) V RAZMERAH SUŠNEGA STRESARaziskava je bila opravljena v sezoni 2014 na Research Farm of the University of Tabriz, Iran. Poskus je bil zasnovan kot poskus z deljenkami na osnovi popolnega naključnega bločnega poskusa s tremi ponovitvami za ovrednotenje učinkov štirih načinov namakanja (namakanje po 60, 80, 100 in 120 mm evaporacije) na osnovi fizioloških in agronomskih lastnosti treh sort koruze (Zea mays L.; 'SC704', 'NS640', 'DC303': zgodnje, srednje in pozno dozorevajoča sorta). Načini namakanja so bili vrednoteni na glavnih ploskvah, sorte koruze na podploskvah. Temperatura lista je pri vseh sortah značilno naraščala z večanjem intervala namakanja, lastnosti kot so indeks vsebnosti klorofila, maksimalna učinkovitost fotosistema II, število zrn na rastlino, masa 1000 zrn, biomasa rastlin, pridelek zrnja in žetveni indeks pa so se z večanjem intervala namakanja značilno zmanjšale. Pozno dozorevajoča sorta ('SC704') je bila v vseh preučevanih lastnostih najboljša, sledili sta ji srednje ('NS640') in zgodaj ('DC303') dozorevajoči sorti. Ugotovljeno je bilo, da pomanjkanje vode lahko potencialno zmanjša uspevanje koruze, a je obseg zmanjšanja odvisen od genotipa in jakosti stresa.
