background and objectives: over the last two decades, a large number of researches have been conducted regarding the importance of nitrogen in sugar beet. this indicate that there were needs to investigate more on nitrogen management to achive higher production and quality because less nitrogen application result in reducing yield and high nitrogen application would increase production costs an...

Soil nitrate and mineralizable nitrogen are used to predict the root yield potential and N fertilizer needs of sugarbeets. Predicting the required N fertilizer for optimum refined sucrose production based on soil test procedures is needed because inadequate N limits root yield and high levels of N may reduce both extractable sucrose and sucrose yield. Sugarbeets (Beta vulgaris L.) were grown at...

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 (...

The optimization of nitrogen application for root crops such as radish is important not only for yield and product quality (sponginess and hollowness) but also for the environment. Therefore, we evaluated the effect of four levels of N application (0, 150, 300 and 450 mg l-1 N) on three radish cultivars (Saxa, Red Fuoko and White Ghiaccio) grown in pots in autumn/winter (from mid-October to mid...

in order to evaluation of morphological selection criteria for salt tolerance screening in wheat (t. aestivum l.) a factorial experiment based on completely randomized design in 3 replications were conducted under greenhouse condition. salinity treatments involved 4 levels: s=1.3dsm-1 (control), 5, 10, 15 dsm-1 from calcium chloride and sodium chloride with 10:1 (na: ca ratio) and another facto...

The multi-faceted benefits of growing crops under protected cultivation are gradually establishing it as a promising technology for vegetable in India. However, the adoption successive cropping patterns soil-based closed structures is leading to buildup soil-borne pathogens and pests, which becoming major hindrance sustainable production these crops, particularly northern plains. Root-knot nema...
