this experiment was conducted to evaluate eight new sugar beet genotypes with different drought tolerance responses to three irrigation schemes (including normal irrigation and early season and continuous stressed) in motahari research station of sugar beet seed institute (sbsi),karaj,iranduring 2005-2006. the study was accomplished in a split plot design (irrigation schemes and genotypes as ma...

in ordet to investigate economic efficiency of five cultural systems in sugar beet crop, including high input, medium input  low input , high  and medium inputs without 3 times irrigation after emergence, an experiment was conducted over  two years  (2002-2003) in agricultural and natural resources research center of khorasan. these systems were analysed by marginal analysis and  linear program...

the study was conducted during 2002- 2007 in the first and last stage of a four-year rotation (sugar beet, forage maize, onion, wheat and sugar beet) at research station of irrigation and drainage rudasht. in each year, four treatments of organic fertilizers (25 and 50 t/ha urban compost and 15 and 30 t/ha sewage sludge) with a control (no organic fertilizer) were studied in a randomized comple...

The study was conducted to investigate the potential of Parkia biglobosa fruit pulp as substrate for citric acid production by Aspergillus niger. Reducing sugar was estimated by 3,5-dinitrosalicylic acid and citric acid was estimated spectrophotometrically using pyridine-acetic anhydride methods. The studies revealed that production parameters (pH, inoculum size, substrate concentration, incuba...

drought stress is one of the most important problems of agriculture and an important factor of plant product reduction. application of absorbent materials can help usage of sporadic rain fall and cause more maintenance of water storage. in order to study the effect of super absorbent polymer, potassium sulfate and manure under drought condition and favorable irrigation on some traits of foxtail...

to evaluate yield and productivity indices of maize and sugar beet intercropping with different planting ratios, a field experiment was conducted in randomized complete block design with three replication at hamedan province in nahavand, in 2013. the planting ratios were 100:0, 75:25, 50:50, 25:75 and 0:100 (maiz: sugar beet) using replacement method. results showed that intercropping had signi...

In a 3-year experiment (2002-2004), five N rates (0, 60, 120, 180, 240 kg N ha-1) were applied to sugar beets arranged in a Randomized Complete Block design with six replications. Experimentation took place under the semi-arid, irrigated conditions of central Greece. The aim of this work was to study the late season response of sugar beet crop to N fertilization as assessed by non-destructive m...
