(In the 3rd of April 2008) and in the morning of (16 April 2008), the temperature reached - 6 ο C in some pistachio gardens of Kerman County especially in Sirjan. The coldness was so high that affected not only on the open flowers but also on bud endings and lop growth, So that the next year product was endangered, as well. In order to study the effect of some treatments and decrease the damage...

in order to study of effects of deficit irrigation on morphological traits and growth indices variation of corn forage (sc. 704) in rasht region, an experiment based on randomized complete design with four treatments and three replication was conducted in 2007 growing season, at research farm of faculty of agriculture, university of guilan. experimental treatments consisted of: no-irrigation, 1...

in order to investigate the effects of water stress and seed priming on seed yield and its components of spotted bean cultivars this study was conducted. the experimental design was implemented in a factorial–split plot based on rcbd with three replications at research field of zanjan university in summer of 2006. main factor was allocated to interaction between two cultivars (tallash and c.o.s...

Summer maize crop development, yield, and water use characteristics under deficit conditions at different growth stages were investigated in this study using irrigation regime treatments the seedling (S), jointing (J), tasseling (T), grain filling (F) 2018 2019 China. Ten set, including three-irrigation application intervals (JTFi, STFi, SJFi, SJTi), two-irrigation applications (STi, JTi, JFi),...

Maximizing utilization of effluent nutrients by forage grasses requires a better understanding of irrigation rate and timing effects. This study was conducted in 1998 and 1999 on a Vaiden silty clay (very-fine, smectitic, thermic Aquic Dystrudert) soil to determine the effects of swine lagoon effluent irrigation rate and timing on bermudagrass [Cynodon dactylon (L.) Pers.] growth, nitrogen (N) ...

This study aimed to evaluate the fruit yield and the distribution of ‘Tommy Atkins’ mango root system under different irrigation regimes in the semiarid region of Bahia. The experimental design was completely randomized with five treatments and three replicates: 1 Irrigation supplying 100% of ETc in phases I, II and III; 2 Regulated deficit irrigation (RDI) supplying 50% of ETc in phase I (begi...

objective: a field experiment was conducted at dorud region, iran, during 2013. the aim of this research  was study on effect of different biofertilizers and irrigation closed time on some agronomic characteristics of sugar beet (beta vulgaris l.). methods: the experimental design was factorial based on rcbd with three replications. treatments were three irrigation closed time [oct-6 (a1), oct-...

population growth as well as global fresh water shortage problem have necessitated the use of unconventional water resources in agricultural sector, as the largest consumer of fresh water, especially in arid and semi-arid regions. in this study, the effect of four irrigation methods on yield, uptake of water and important nutrients, and the salt accumulation in soil was investigated using a com...

The purpose of this study is to investigate the interactions between irrigation and fertilizer treatments on soil NO3 (-)-N content and vertical distribution under drip fertigation in greenhouse tomatoes. Randomized block design with three replications and the treatments consisting of three levels of irrigation and three levels of N fertilizer were used. Three irrigation levels were W1 (100%  E...

This study was conducted to investigate the effects of different restricted irrigation strategies on peach trees. Sustainable and regulated deficit treatments were applied during 2018/2019 production season in a commercial plot “Bénédicte” variety located at Atlas Mountain’s region Morocco. Five tested: T1, T2 T3 with an application respectively 125% (over-irrigation), 100% (control) 75% (defic...
