Conventional procedures are inadequate for optimizing the concentrations ofnutrients to increase the sugar yield. In this study, an artificial neural network(ANN) was used to optimize the Ca, Mg, N, K and Na content of the storage rootto increase sugar yield (Y) by increasing both sugar content (SC) and root yield(T). Data from three field experiments were used to produce a wide range ofvariati...

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...

Salicylic acid (SA) is a phenolic compound and its foliar application shows regulatory effects on plants. In this research, Ajowan (Carum copticum) plants were treated with 0, 0.5, and 1 mM SA and proline, total phenol, chlorophylls, carotenoids, soluble sugar, N, P, and K contents were studied. Results showed that application of SA affected both quantitative and qualitative traits of ...

this study was conducted in split plot design based on a randomized complete block design in naghadeh region, urmia, iran in 2009-10. two sowing patterns including a1) single row planting with 50 cm between-row spacing, and a2) two rows planting on the hill with 40 cm distance and 50 cm between-row spacing (40×50) were allocated to main plots and four furrow compactions including b1) control, b...

data related to holstein dairy cattle from 1987 to 2004 were obtained from animal breeding center of iran to estimate the genetic and phenotypic trends. variance components and genetic parameters of the first lactation records were estimated using restricted maximum likelihood method and aireml algorithm through matvec program. animal breeding values were predicted through multiple-trait animal...

resistance of 16 sugar beet cultivars to cercospora leaf spot was evaluated in ghaemshahr region. the experiment was conducted in a complete block design with six replications and disease severity of cultivars was measured two times. as a winter crop the root yield of cultivars and their disease severity compared under natural cercospora infection in dezfoul area in a complete block design with...

This study aims to determine the effect of concentration kurut wood and jackfruit on yield, pH, percentage reducing sugars palm sugar. experiment used a completely randomized design (CRD) which consists 6 treatments, i.e., 0 g/L, 3 4 5 7 g/L. The data were analyzed by Analysis Variance (ANOVA) using Co-Stat software posthoc analysis for chemical score Orthogonal Polynomial Method (MOP). Statist...

models can be used to predict crop yield and inputs levels such as fertilizer, in order to conduct programming for the management of probable future crisis. in this study, based on the model, the effect of nitrogen fertilizer on dry matter partitioning in shoot and root of sugar beet was predicted. for model construction, data were collected from an experiment conducted in karaj city in 2001. i...
