In the conditions of the steppe zone of the Samarkand region, 5 local ancient varieties of spring soft wheat of various geographical origin were studied. The aim of the research is to evaluate the grain quality indicators of ancient wheat varieties in various meteorological conditions and to identify sources of protein and gluten content for use in practical breeding.
The negative effect of abundant moisture (26%) during the filling period and high air temperature (26%) in the phase of grain ripeness on the quantity and quality of gluten was found. It is shown that the studied ancient varieties in typical meteorological conditions of the steppe zone of the Samarkand region stably form first-class grain: the maximum protein content in the grain is 13.1-14.5%, raw gluten-33.2-35.4%, the number of drops-319-340 s, nature-758-779 g/l. At the same time, the potential of rheological properties of the dough in varieties exceeds the norms for strong wheat: dough liquefaction-39 u. f., valor metric assessment-60-72 u. V. calorimeters.
The volume of bread-678-773 ml with a total score of 3.0-4.8 points. Studies have shown that the meteorological conditions of the year cause a high phenotypic variability of the rheological properties of the dough (CV=51.4-64.3 %), the average variability of signs: the number of falls (CV=12.2-14.0%), the mass fraction of protein (CV=9.1-12.2 %, the overall score of bread (CV=8.1-11.3 %). On the basis of the conducted research, the source varieties for indicators of technological properties of grain for use in practical breeding programs are identified.

The article discusses the problems of accelerating hydrothermal treatment in the preparation of wheat grains grown in dry climates for varietal grinding. In it, the effect of activated water on the natural mass of wheat grain was studied experimentally. The differences in changes in the natural mass of wheat grain under the influence of activated and drinking water are theoretically explained.

The experiment was conducted in Agriculture filed of Lovely Professional University, Jalandhar with wheat variety viz. HD 3086 to know the effect of foliar application of iron on nitrogen uptake and its combined impact on growth and yield of wheat. The plot design was RCBD with three replications and eight treatments. T1: Control (without fertilizer), T2: Control (with RDF), T3: RDF+ FeSO4 + Urea (at flowering stage), T4: RDF + FeSO4 (at flowering stage), T5: RDF + FeSO4 + Urea (at milking stage), T6: RDF+ FeSO4 (at milking stage), T7: RDF+ FeSO4 + Urea (at pre-maturity), T8: RDF + FeSO4 (at pre-maturity). The observed parameters plant height, length of spike, number of tiller, effective number of tillers, test weight of grain, number of spike lets per spike, number of grain per spike were taken at regular interval of 60, 90 ,120 DAS. In case of yield parameter the maximum test weight was recorded in T3 (49.75) and minimum was in T3 (45.09). For harvest index maximum value was recorded in T3 (45.42) and minimum in T1 (43.49). According to result, better growth and yield parameter was observed in treatments T3 due to foliar spray of iron and urea. Iron acts as catalyst and regulate many enzymatic activities which helps in better growth and increase in the yield, whereas urea is a source of nitrogen and in plants growth nitrogen play very important role because it helps in the synthesis of chlorophyll and many other activities.

A field trail was conducted to evaluate the efficacy of foliar application of iron on nutrient availability in wheat grain. The plot design was RCBD with three replications and eight treatments. T1: Control (without fertilizer), T2: Control (with RDF), T3: RDF+ FeSO4 + Urea (at flowering stage), T4: RDF + FeSO4 (at flowering stage), T5: RDF + FeSO4 + Urea (at milking stage), T6: RDF+ FeSO4 (at milking stage), T7: RDF+ FeSO4 + Urea (at pre-maturity), T8: RDF + FeSO4 (at pre-maturity). After harvesting, estimation of nutrients in grain revealed that for most of the nutrients application of Fe at flowering and miliking stage has great impact on increased nutrients in grain.

Aim of the study was to predict protein content of wheat grain stored for one year at 4˚C temperature using selected Near Infrared Near Infrared (NIR) wavelengths and Chemometrics. The spectra of grains were measured in reflectance mode with the use of lab built NIR filter based pre dispersive spectrometer ranging from wavelength 750nm to 2580 nm. Wavelength set was divided into two sets for all the stored samples. The chemometric methods applied to the reference data and recorded NIR data were analyzed based on principal component analysis (PCA) scores, partial last squared regression (PLSR) model. R2 values were 0.955, 0.997 for prediction of protein content from PLSR Wavelength Set I and II respectively. Wavelengths with high β correlation coefficients were defined. This study showed that near infrared spectroscopy has potential to distinguish wheat grains stored refrigerator conditions.

A field experiment was carried out in the Badia of Al-Muthanna, Faidat Umm Al-Shih, for the 2018-2019 season, to determine the effect of adding levels of agricultural polymer and levels of irrigation on some chemical and physical properties of the soil and the production of wheat crop (Triticum aestivum L.). The experiment included three levels of Absorption Sup super (ASP Polymers (0, 40 and 80) kg ha (P0, P1 and P2) and four levels of irrigation (W3, W4, W5 and W6). Three seasons, four seasons, five seasons, and six seasons, the soil was divided into three replicates to find out the best number of irrigations with the best amount of polymer added in production and the characteristics of the studied soil. The results showed the effect on the soil properties, the addition of the agricultural polymer at a level of 80kg ha and the irrigation level W6 showed a significant decrease in the electrical conductivity of the soil, reaching 1.9 decimens, the CEC values ​​also increased to 13.80 cmol, which is the highest level, and the bulk density values ​​decreased to the level of 1.39 gm cm3, which was the lowest level in the experimental treatments. As for the soil reaction, it reached the lowest level (7.60 pH) against the level of polymer P1, as for the effect on wheat production, it was significant, as the biological yield reached the polymer level 80 kg ha, 11.95 megagrams ha-3, which was the highest production achieved by the experimental treatments, while the yield of the wheat crop was 5.55 megagrams ha-3, which was the highest. The effect of irrigation levels on biological production and productivity reached the highest irrigation level (W6), where it was respectively 11.40 and 4.51 mg ha-3 as an average, as the study showed that the addition of 80 kg/ha agricultural polymer with six irrigations per season gave good productivity and significantly affected Positive on soil physical and chemical properties in desert soils
