In this study, the effect of nitrogen doses on yield and quality characteristics of durum wheat varieties (Levante, Zenit, Yelken 2000, Dumlupınar, Eminbey, Altın, Ç-1252, and Kızıltan-91) was investigated. The research was conducted in Isparta ecological conditions in 2010-2012 seasons using different nitrogen doses of 0, 5, 10 and 15 kg/da N. The experiments were carried out for two years using randomized complete block design with three replications in factorial arrangement. All of the phosphorus (6 kg/da P2O5) and half of the nitrogen were given with sowing and the other half of the nitrogen was given during the tillering period. As a result of two years in this study, it was determined that nitrogen doses have a significant effect on all examined characteristics (number of spikes per m2, grain yield, 1000 grain weight, test weight, vitreousness and crude protein ratio). But the effect of nitrogenous fertilization varied significantly according to the varieties. In general, increasing in the amount of nitrogen above 10 kg/ha did not create a statistically significant increase in other characteristics except 1000 grain weight. As a result when grain yield and quality characteristics are taken into consideration, 10 kg/da N dose and Çeşit-1252, Altın, Kızıltan-91 and Dumlupınar varieties could be recommended in Isparta conditions.

The magnitude of genetic inheritance and expected genetic advance are important for the prediction of response to selection in diverse environments and provide the basis for planning and evaluating breeding programs. This work investigated the inheritance of traits related to drought in wheat under natural drought conditions. Cross combinations were made to produce F1 and F2 hybrid populations, which were evaluated in a randomized completed block design with three replications at University of Agriculture, Faisalabad, Pakistan. Six wheat varieties/lines and six derived F2 hybrids were studied to ascertain heritability and genetic advance for plant height, days taken to maturity, number of tillers per plant, spike length, number of grains per spike, 1000-grain weight, and grain yield per plant. Data were collected and subjected to statistical genetic analyses. Heritability estimates and expected genetic advance for plant height, days taken to maturity, number of tillers per plant, 1000-grain weight and grain yield per plant were high for the entire cross combinations while the estimates for spike length and number of grains per spike were relatively low. Our results suggest that improvement for these characters should be faster because of higher heritabilities and greater phenotypic variation. Prospects of genetic improvement for all the characters studied are evident. The most promising cross combinations were WL60 × LU26S and WL61 × LU26S. These traits, therefore, deserve better attention in future breeding programs for evolving better wheat for stress environments. <br /><br />

One of the main problems faced in corn cultivation, especially in Cerrado regions, is the deficiency of micronutrients. Among the micronutrients essential for the development of plants, boron (B) stands out for participating in a series of physiological processes. Based on this, the present work aimed to evaluate the performance of corn under fertilization with different sources and doses of boron. The randomized block design in a 4x3 factorial scheme was used. Four boron doses (0, 1, 2, and 3 kg ha-1) and three nutrient sources (boric acid, borax, and ulexite), applied in topdressing, were evaluated. Plant height (cm), stem diameter (mm), first ear insertion height (m), ear length (cm), ear diameter (mm), number of rows per ear, number of grains per row, 1000-grain weight (g), and grain yield (kg ha-1) were evaluated. It was concluded that the boron sources and doses used did not influence the results of plant height, first ear insertion height, number of rows per ear, and grain yield. The three doses evaluated provided increases in stem diameter, with a dose of 2.08 kg ha-1 being the one with the highest average. The application of borax and ulexite results in higher values of ear diameter, number of grains per row, and 1000-grain weight. The dose of 1.74 kg ha-1 of boron provides the highest 1000-grain weight.

To evaluate the effect of Zinc fertilizer on performance of wheat cv. BARI gom30, an experiment was carried out at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, from November 2015 to March 2016. The experiment comprised four levels of Zinc (Zn) viz., 0, 1.5, 2 and 2.5 kg/ha. The experiment was laid out in a randomized complete block design with three replications. Application of Zinc (Zn) plant height, number of total tillers/plant, number of effective tillers/plant, spike length, number of fertile spikelets/spike numbers of sterile spikelets/spike number of grains/ spike, grain yield and straw yield were found significant. But there was no significant effect of the treatment on 1000-grain weight. The highest number of total tiller/plant (4.42), number of effective tillers/plant (3.92), number of grains/spike (47.70), 1000-grain weight (47.73 g), grain yield (5.06 t/ha), straw yield (6.21 t/ha) was obtained from 2 kg Zn/ha. The highest plant height (94.08 cm), spike length (9.92 cm), number of fertile spikelets/spike (19.59) and sterile spikelets/spike (3.22) and harvest index (46.16%) were recorded at 0 kg Zn/ha respectively. The control treatment indicated the lowest value for the yield attributing characters except the number of sterile spikelets/spike. Grain yield was found to be significantly and positively correlated with number of grains/spike and straw yield. It is recommended that application of 2 kg Zn/ha is the best for maximum yield of BARI gom30.

A field experiment was conducted to investigate the effect of different concentrations of K2SO4 and KNO3 foliar application (2 and 4%) on the growth of wheat (cv. Watan) at Soil Salinity Research Institute (SSRI) farm, Pindi Bhattian, Punjab, Pakistan during Rabi season, 2007. Treatments were: soil application K2SO4 , KNO3, 2 and 4% K2SO4, 2% KNO3 + 2% K2SO4, 4% KNO3 +2% K2SO4, 2% KNO3 + 4% K2SO4 ,4% KNO3+4% K2SO4 . Treatments were assigned using randomised complete block design with three replications. The crop was harvested at maturity, data on tillering, plant height, spike length, number of grains/spike, 1000-grain weight, straw and wheat yields were recorded. Tillering, number of grains/spike, 1000-grain weight and wheat yield significantly (P £ 0.05) increased by different levels of doses. 2% K2SO4 and 4% K2SO4 improved the tillering capacity of wheat compared with the control. The combination of 2% KNO3 + 4% K2SO4 attained the highest grain yield (2825 kg/ha) which was statistically at par with 2% K2SO4 (2795 kg/ha). The lowest grain yield (2129 kg/ha) was received by the control (soil applied K2SO4). Grain yield after spraying was up to 31% higher than in the control.

This study was conducted during two crop seasons to investigate the effect of nitrogen fertilizer quantity and application form on grain yield and quality in Eskisehir Transitional Zone Agricultural Research Institute by using seven bread wheat cultivars in rainfed and eight in irrigated conditions. In the study, urea as a source of nitrogen was applied in heading time (Zadoks 59) in granular and foliar form. In all treatments grain yield, some technological quality characteristics were determined of the genotypes. In both conditions while sedimentation value, protein content, aggregation energy (AGGEN) and maximum torque (BEM) values increased, peak maximum time (PMT) decreased with foliar urea applications. it was determined that there were statistically significant differences between the varieties in terms of SDS sedimentation values in both rainfed and irrigated conditions. In this study, In irrigated and rainfed conditions the values obtained from foliar urea applications compared to granular ones with relation higher bread quality in the genotypes which contain Glu-A1 locus 2* subunit; 9% for grain yield, 6.5% for protein content, 17.0% for sedimentation value and 3.8% increase of BEM, Glu-D1 locus; 5+10 subunit 8% for grain yield, 5.6% for protein content, sedimentation 16.0%, 6.4% for BEM increase, for Glu-B1 locus; 7+9 subunit 7.0% for grain yield, 6.0% for protein content, 19.6% for sedimentation value, and 7.2% for BEM value increase. This study was observed that the foliar application during the heading time provided the improvement of bread wheat grain yield and quality characteristics.

Nutri-millets offer copious micronutrients like vitamins, beta-carotene etc. In this present day, all the millets are amazingly superior and are therefore, the result for the malnutrition and obesity that affects a vast majority of the Indian population. They have numerous beneficial properties like drought resistant, good yielding in areas where water is limited and they possess good nutritive values. The prospective water scarcity in semi-arid regions disturbs both normal as well as managed environments, which limits the cultivation of crops, fodder, and other plants. The issues faced by the rain-dependent farming of these semi-arid regions are primarily the unpredictability of the monsoon. Probability analysis of rainfall events are believed to contribute in deciding sowing dates for the current season and for successful crop production in semi-arid environments. The present study was carried out in semi-arid condition to quantify the performance of nutri-millets in the rain dependent farming. The experiment was laid out under factorial randomized block design with 3 replications. The treatments comprises of crop factor viz., Sorghum [Sorghum bicolor (L.) Moench] (C1) and, little millet [Panicum sumatrense Roth ex Roem. & Schult] (C2) and sowing window factor viz., sowing based farmer’s practice (M1) i.e. on 31st standard meteorological week (SMW); Sowing at 33rd SMW based on 50% rainfall probability (M2); Sowing at 38th SMW based on 75% rainfall probability (M3), Sowing window as per the current weather forecast, for this season on 35th SMW (M4).It is evident from the study that Sowing sorghum at 38th standard meteorological week based on 75% rainfall probability recorded higher grain yield, rain water use efficiency with elevated iron and calcium content. This shows that different sowing dates have significant influence on grain yield and quality of nutri-millets.

The present investigation was carried out for yield and quality related traits in the F2 and F3 populations of twenty eight rice cross combinations developed from five aromatic (Pusa 1121, Improved Pusa Basmati, Basmati 370, Sumathi and RNR 2354) and three non-aromatic (BPT 5204, Akshyadhan and NLR 145) parents. In F2 generation, among the yield characters, the highest values of phenotypic co-efficient of variation (PCV) and genotypic co-efficient of variation (GCV) were recorded for the number of filled grains/panicle followed by grain yield per plant while the lowest values were recorded for days to 50% flowering. However, for the grain quality characters the highest PCV and GCV values were recorded for head rice recovery and lowest for kernel breadth. In F3 population, higher magnitudes of PCV and GCV were recorded for the number of filled grains/panicle and panicle weight, indicating greater scope of obtaining high selection response for these traits. High heritability in narrow sense along with medium to high genetic advance was noticed for the traits like days to 50% flowering, 1000 grain weight and the kernel traits.

The experiment was conducted in pot at the net house of the department of Agronomy, Sher-e-Bangla Agricultural University, Dhaka during the period from November, 2018 to March, 2019to find out the optimum dose(s) cowdung to mitigate the water deficit effect on wheat. The experiment comprised of two factors viz. factor A: Five levels of cowdung, i) C0= Control (No cowdung), C1= 25% less cowdung of recommended dose, C2 = Recommended dose of cowdung, C3 = 25% higher cowdung of recommended dose and C4 = 50% higher cowdung of recommended dose, and factor B:  four levels of water deficit at, i) D0 = Control (No water deficit), D1= Crown root initiation stage (20-19 DAS), D2 = Booting stage (45-54 DAS) and D3= An thesis stage (55-64 DAS). The experiment was laid out in a Factorial R and omized Complete Block Design with three replications. The test crop variety was BARI Gom28. The result reveled that cowdung level had positive impact on yield of wheat under water deficit condition, and 50% higher cowdung of recommended dose (C4) gave the highest grain yield (5.12g plant-1). The particular treatment also produced the highest number of effective tillers plant-1 (5.25), spike length (10.39 cm), spikelet spike-1 (15.72), grains spike-1 (32.56), grains spikelet-1 (2.07) and 1000-grain weight (47.32 g) of wheat. The treatment C3 (25% higher cowdung of recommended dose) also gave statistically similar yield with C4 treatment. In respect of water deficit imposition treatments, grain yield was found the highest in control treatment which was statistically similar with water deficit imposition at booting stage treatment (D2). These two treatments also showed the higher and similar number of effective tillers plant-1 (4.86 and 4.58), spike length (10.53cm and 10.11cm), spikelets spike-1(15.50 and 15.19), grains spike-1 (34.10 and 30.17), grains spikelet-1 (2.20 and 1.98) and 1000-grain weight (45.42g and 45.36g, respectively). Regarding the interaction of levels of cowdung and water deficit imposition at different stages of plant growth, C4D0 and C3D0 were highest yielder which was attributed to higher 1000-seed weight, number of effective tillers plant-1, spikelets spike-1 and grains spike-1. Contrary, 25% higher cowdung than recommended dose (as it saved 25% cowdung) seems promising to overcome yield loss due to water deficit imposition at booting stage of wheat (D2). However, application of cowdung (12.5 t ha-1) was found effective to combat water deficit at booting stage (D2) of wheat compared to other growth stages. Bangladesh Agron. J. 2021, 24(1): 93-100
