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.

The experiment was carried out during the period of June to November 2013 at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh with a view to examine the yield performance of some transplant aman rice varieties as influenced by different levels of nitrogen. The experiment consisted of four varieties viz. BRRI dhan49, BRRI dhan52, BRRI dhan56, BRRI dhan57 and four levels of N viz. 0, 46, 60 and 75 kg ha-1. The experiment was laid out in a randomized complete block design with three replications. Variety, levels of N and their interactions exerted significant influence on yield contributing characters and yield of transplant aman rice. Among the varieties, BRRI dhan52 produced the tallest plant (117.20 cm), highest number of effective tillers hill-1 (11.28), grains panicle-1 (121.5) and 1000-grain weight (23.65 g) whereas the lowest values of these parameters were produced by BRRI dhan57. Highest grain yield (5.69 t ha-1) was obtained from BRRI dhan52 followed by BRRI dhan49 (5.15 t ha-1) and the lowest one (4.25 t ha-1) was obtained from BRRI dhan57. In case of N, the tallest plant (111.70 cm), highest number of total tillers hill-1 (12.34), grains panicle-1 (133.6), 1000-grain weight (24.55 g) and grain yield (5.64 t ha-1) were obtained from 75 kg N ha-1 and the lowest values were obtained from control. BRRI dhan52 fertilized with 75 kg N ha-1 showed best performance with respect to all the parameters studied. The overall results suggest that BRRI dhan52 should be fertilized with 75 kg N ha-1 for getting higher yield under the agro-climatic condition of BAU.J. Bangladesh Agril.

Abstract In order to study of effects of nitrogen fertilizer and cycocel on yield, yield component and dry matter mobilization of wheat (Triticum aestivum L.) a factorial experiment was conducted based on randomized complete block design with three replications during 2014. Treatments were included nitrogen rates in four levels (without nitrogen application as control (N0) and application 80 (N1), 160 (N2) and 240 (N3) kg ha-1 urea) and four cycocel levels (without cycocel as control (C0), application of 500 (C1), 1000 (C2), 1500 (C3) ppm). Results showed that cycocel application increased chlorophyll index, photochemical efficiency of PSII (Fv/Fm) and dry matter mobilization from shoots and stem. Application of nitrogen and cycocel reduced dry matter mobilization from shoots and stem, contribution of remobilization from shoots to grain and stem reserve contribution in grain yield. Application of nitrogen and cycocel as N3C3 had 58.5% and 46.26% more dry matter mobilization from shoots and stem in comparison with N3C0. The highest 1000-grain weight by 28.90 and 28.54 g, respectively, belonged to application of cycocel as C2 and C3 and the lowest 1000-grain weight by 26.93 g belonged to the C0. The highest grain yield (1.068 g per plant), number of grains per ear (37.36) and 1000-grain weight (28.77 g) were obtained in application of 240 kg ha-1 urea. It seems that the increase of Fv/Fm ratio due to current photosynthesis in plants that were grown under cycocel and nitrogen treatments decreased mobilization of dry matter and stem reserves to grain yield. Generally, it was concluded that nitrogen and cycocel can be as a proper tool for increasing wheat yield.

. The effect of different S levels (0, 25, 50 and 75 kg S/ha) on growth and ionic concentration  of wheat variety Inqlab-91 directly sown on saline-sodic soil (ECe=5.65 dS/m, pH=8.57 and SAR=17.38) was evaluated in a field experiment. Treatments were arranged using randomized complete block design (RCBD) with three replications. The crop was harvested at maturity, data on tillering, plant height, spike length, number of grains/spike, 1000- grain weight and yields (grain and straw) were recorded. Na, K, Ca and S concentrations in grain and straw were estimated using atomic absorption spectroscopy. Tillering, number of grains/spike, 1000- grain weight and grain yield significantly (p :: 0.05) increased by enhancing the S application. Maximum wheat yield (4.66 t/ha) was recorded when S was applied at 75 kg/ha, which was 43% more than the control treatment. Maximum number of tillers/plant (161) and number of grains/spike (56) were recorded with sulphur applied at 75 kg/ha. Positive correlation (r = 0.85), (r = 0.88) between calcium, potassium and negative correlation (r = -0.84) between grain sodium content and wheat grain yield was recorded. It indicates that presence of significantly higher Ca and K contents of grain receiving S application might possibly help plants to attain more Ca and K and avoided sodium uptake to alleviate salinity/sodicity stress. Economical analysis showed that maximum value cost ratio (5.5:1) was achieved with the application of 25 kg S/ha.

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.

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 />

Eleven genotypes of bread wheat were crossed with three testers in the rabi season of 2018-19 inline x tester mating fashion to obtain 33 F1 hybrids, which were evaluated with parents and two standard checks of wheat viz., UP 2855 and HD 2967. The experiment was laid out in randomized block design with three replications at Norman E. Borlaug Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar in the rabi season 2019-20. Observations were recorded on various qualitative and quantitative characters including grain yield. The results obtained revealed significant differences among all the genotypes, indicating the presence of aconsiderable amount of genetic variability. The cross combinations SOKOLL x HI 1621, followed by QBP 12-11 x HI 1621, NAC/TH.AC//3*PVN/3/MIRLO/BUC/4/ 2*PASTOR/5/… x HD 3237 were observed to be the better heterotic F1s in terms of grain yield. The hybrid QLD 75 x HI 1621 was identified as the best heterotic combination for grain weight per spike and harvest index. Whereas, for grains per spike F1, NW 6036 x HI 1621, for 1000 grain weight F1, SOKOLL x HD3237, for spike length F1, NAC/TH.AC//3*PVN/3/ MIRLO/BUC/4/2*PASTOR/5/… x HD 3237, for peduncle length F1, VORB/4/D67.2/PARANA 66.270 x HI 1621 and for days to 75% heading and days to maturity F1, PRL/2*PASTOR*2//FH6-1-7/3/KINGBIRD#1//… x PBW 725 were observed to be the better heterotic combinations. The crosses with higher heterotic values may provide an opportunity for isolation of desirable purelines in advanced generations.

To study the effect of irrigation levels and foliar application of fertilizers on some agronomic and oil characteristics of castor bean, an experiment was conducted at the East Azarbaijan Agricultural Research and Education Center, Tabriz, Iran in 2017-2019 cropping seasons. The experiment was laid out as a split-plot design based on a completely randomized block design with three replications. In the present study, main cluster length, number of branches, number of capsules per plant, number of seeds per capsule, 100-grain weight biological yield, grain yield, oil percent and oil yield were measured. Irrigation intervals (normal irrigation (irrigation after 60 mm), irrigation after 80 mm and 140 mm of evaporation) was established as main plots and the foliar applications of fertilizers (N, K, S, N + K, and N + S, K + S, N + K + S and control) input as sub-plots. The results showed that, except for the oil percentage, all the examined traits were decreased by water limitation. The highest values of the traits, other than the 100-grain weight, were obtained for foliar application of N + K + S. This treatment improved the grain yield per unit area under normal irrigation and moderate irrigation and severe stresses by 62.76%, 41.46% and 28.98% respectively. Thus, the foliar application of S (2000 ppm) + N (3000 ppm) + K (3000 ppm) fertilizer is the best treatment for mitigating some harmful effects of water deficit on castor bean.

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
