In order to study the effect of Salinity levels of Sodium chloride and Soil type on the characteristics of some grown seeds and the resistance rate of Fusarium fungi (quantitative length evaluation of necrotic part in plants gorget) in biotypes of safflowers, an experiment was factorically conducted by using two salinity levels of sodium chloride (20% and 50% salinitys), seven biotypes of acanaceous and non-acanaceous safflowers (Iraqi 222, IL111, K.H.64.68, and Varamin 295,Local Isfahan , Padideh and 340779), two types of soil (clay sandy-clay), in a three times randomized complete block design. The variance analyzing results showed that between the levels of all factors, there was meaningful difference for 2 studied characteristics. According to the results obtained from the comparison of factors means, genotypes of Iraqi 222, K.H.64.68 and 340779 under the condition of 20% salinity and genotype of Iraqi 222 under the condition of 50% salinity contained the most numbers of grown seeds. On the other hand the most resistance rate against Fusarium mushrooms was related to genotype K.H.64.68 under the condition of clay soil and 20% salinity, genotype IL111 under the condition of clay soil and 50% salinity and local genotype of Isfahan under the condition of sandy-clay soil with 20% salinity, Based on the results obtained from the linear regression and simple correlation coefficient there was positive and meaningful correlation between two evaluated characteristics in the probability level of 1% and the relation between them was estimated as linear and positive one (y=0/545+0/234X), where X refers to the number of grown seeds and y refers to the resistance against Fusarium.

This study was conducted to assess the effect of soil salinity on leaf area (LA), the number of days to flowering (DF), plant height (PH), and grain yield. Overall, 60 wheat genotypes were used, including 49 CIMMYT elite lines and 11 commercially grown Egyptian wheat cultivars. During two growing seasons (2017 and 2018), the genotypes were grown in non-saline (S0) and saline (S1) soils. A randomized complete block design with three replicates was used in a split-plot arrangement. Salinity levels were randomly assigned to the main plots, while genotypes were randomly assigned to the subplots. The obtained results showed that the saline soil adversely affected the evaluated genotypes. Furthermore, a highly significant effect of genotypes × salinity was observed on grain yield and its attributed traits. Based on salinity indices results, some of the imported wheat genotypes outperformed the Egyptian cultivars in grain yield under salinity stress conditions. The results further indicated that Sakha-93, C-31, and C-40 were the most salt-tolerant genotypes. The best performing line among the CIMMYT lines was C-31, which recorded the highest grain yield under none-saline and saline soil in the two seasons of study.

Tomato (Lycopersicon esculentum Mill.) cv. Santa Clara was grown on a silt clay soil with 46 mg dm-3 Mehlich 1 extractable K, to evaluate the effects of trickle-applied K rates on fruit yield and to establish K critical concentrations in soil and in plant petioles. Six potassium rates (0, 48, 119, 189, 259 and 400 kg ha-1 K) were applied in a randomized complete block design with four replications. Soil and plant K critical levels were determined at two plant growth stages (at the beginning of the second and fourth cluster flowering). Total, marketable and weighted yields increased with K rates, reaching their maximum of 86.4, 73.4, and 54.9 ton ha-1 at 198, 194, and 125 kg ha-1 K , respectively. At the first soil sampling date K critical concentrations in the soil associated with K rates for maximum marketable and weighted yields were 92 and 68 mg dm-3, respectively. Potassium critical concentrations in the dry matter of the petioles sampled by the beginning of the second and fourth cluster flowering time, associated with maximum weighted yield, were 10.30 and 7.30 dag kg-1, respectively.

An experiment was conducted at Fruit Tree Improvement Project, Fruit Tree Improvement Programme, Bangladesh Agricultural University-Germplasm Center (FTIP, BAU-GPC), Bangladesh Agricultural University (BAU), Mymensingh during the period of April 2020 to June 2020 to study the performance of selected mango rootstocks for the saline area. The two-factor experiment consisted of four mango rootstock varieties such as V1 = BAU Aam-9, V2 = BAU Aam-6, V3 = BAU Aam-4 and V4 = Amropali and six salinity treatments namely control S1 = 0 dSm-1, S2 = 4 dSm-1, S3 = 8 dSm-1, S4 = 10 dSm-1, S5 = 12 dSm-1 and S6 = 14 dSm-1. The experiment was conducted following randomized complete block design with three replications. Results revealed that rootstock line and salinity levels had significant influences on various rootstock characters viz. length of rootstocks, number of leaves and percent rootstocks success and survivability. In case of varietal effect, the highest number of leaves (32.44) found in BAU Aam-6 and the lowest number of leaves was recorded in Amropali (22.55) at 90 days after transplanting. The longest rootstock length observed in 90 DAT which (54.83 cm) found in BAU Aam-9and shortest rootstock recorded in Amropali (47.94 cm). The highest survivability (51.44%) was recorded in BAU Aam-9 and the lowest survivability recorded in Amropali (33.88%). In case of salinity treatments, the highest survivability (95.83%) was recorded in control and the lowest survivability (0.00%) recorded in 14 dsm-1 at 90 DAT. Interaction of rootstock varieties and different salinity treatments showed significant variation on the length leave and survivability of rootstocks at 90 DAT. The maximum number of rootstock leaves recorded in V2S2 (46.33) and lowest number of leave recorded in V4S6 (7.66). The highest rootstock length was found in V1S3 (78.00 cm) and lowest in V1S2 (21.66 cm). The highest Survivability (100 %) observed in V1S1, V1S2, V2S1, V2S2 and V4S1. From the above mentioned it can be said BAU Aam - 9 and BAU Aam – 6 rootstock varieties performed best from 0-8 dSm-1 salinity. The overall salinity tolerance was graded as follows: BAU Aam - 9>BAU Aam – 6> BAU Aam-4>Amropali rootstock line. SAARC J. Agric., 19(1): 93-102 (2021)

TThe physiological and phytochemical responses of red amaranth (Amaranthus tricolor L.) and green amaranth (Amaranthus dubius L.) to different salinity levels were determined in two experiments conducted in Vietnam. Both experiments were performed in a net house involving pot experiments arranged in randomized complete block design (RCBD) with three replications. Two genotypes of amaranth were grown in garden soil, saline soil, 50% garden soil: 50% saline soil and 25, 50 and 100 mM NaCl. Salinization was imposed at 7, 14 and 21 days after transplanting. Results indicated that salt stress decreased growth parameters and biomass production in all treatments except for 25 mM NaCl. Na+ and Cl- content accumulated in both shoot and root, however, root had greater NaCl content than shoot. Total phenolics, total flavonoid content and antioxidant activity increased with increasing salinity levels from 25 mM to 50 mM NaCl; however, at 100 mM NaCl, all these parameters decreased. These results showed that red amaranth was more tolerant to salinity stress than green amaranth.

The experiment was performed using locally manufactured subsoiler plow provided with wings on the outside of shallow tines feet to study the impact of adding the wings and depth of tillage on the disturbance area of soil, soil pulverization index (mean weight diameter, MWD) and the equivalent energy of soil pulverization (Eq EP) in clay soil. This experiment was done in Randomized Complete Block Design (RCBD), with three replications having a factorial experiment. Three tillage depths (40, 50, and 60cm) with and without wings on the feet of shallow tines were used. The results showed that the impact of adding wings and tillage depths had a significant effect on the disturbance area, soil pulverization index and the equivalent energy of soil pulverization (p < 0.05). The treatment of adding wings on shallow tines (S+shw) has pre-eminence in studied factors. The disturbed area increased by 11.11, 14.29 and 9.80%, the MWD decreased by 27.33, 32.31 and 19.38% and the Eq EP increased by 43.19, 53.03 and 25.13% when the depth of tillage increased from 40, 50 and 60cm respectively.

A field experiment was conducted on a sandy clay soil to screen eighteen groundnut genotypes for their sulphur (S) efficiency and to know its effect on growth, yield and sulphur availability and uptake. There were two levels of sulphur (0 and 40 kg ha-1) applied as gypsum basally and replicated thrice in a randomized block design. Results revealed that inclusion of 40 kg S ha-1 as gypsum significantly improved the growth and yield attributes of all the groundnut genotypes besides increasing the kernel and haulm yield. Soil available sulphur and sulphur uptake by the genotypes were also considerably improved by sulphur addition which differs widely among them. Several indices were computed for assessing the sulphur efficiency and found that, the genotypes, VRI 6, CO 7, TMV 7, TMV 13, VRI 5, VRI 3, CO2 and CO 6 were found efficient and responsive for sulphur application while VRI 8, and TMV 10 were inefficient but found responsive. However the varieties such as Local, VRI 4, CO 3, VRI 2, VRI 7, TMV 2, ALR 3 and BSR 1 were highly non responsive and inefficient in utilizing the applied sulphur.

Treatment with short-chain alcohols such as methanol and ethanol have been found to stimulate the performance of a number of crops. Container experiments were conducted in the Dominican Republic to determine the effect of methanol and nitrogen (N) treatments on the yield of cilantro (Coriandrum sativum). Plants were individually grown in plastic containers (15 × 15 cm) filled with loamy clay soil (4.3% organic matter) fertilized at planting with 20, 40, 60, and 80 kg N/ha. Methanol was sprayed in aqueous solutions (0%, 5%, 10%, and 15 %) when plants reached the three true leaf stage. A randomized complete-block design with a factorial arrangement and five replications was utilized. Cilantro plants were harvested 40 days after emergence and shoot fresh and dry weight were determined. Resulting data was subjected to analysis of variance and regression analysis. No significant nitrogen and methanol interactions were detected. In the range of rates tested in this study, methanol did not significantly influence cilantro shoot fresh or dry weight. Cilantro yields increased when N rates were increased from 20 to 40 kg per ha, reaching a plateau at higher N rates.

The effect of boron (B) and molybdenum (Mo) foliar fertilization on `Spineless Beauty' zucchini (Cucurbita sp.) fruit yield was studied in Nigua, San Cristobal, Dominican Republic. Field trials were conducted in a loamy clay soil containing 0.3 parts per million (ppm) of B and no detectable amounts of Mo (detection limit 0.1 ppm). Zucchini was direct-seeded at a distance of 1 m between rows and 0.5 m within rows. Fertilization (except B and Mo applications) and other production practices were implemented as recommended. A randomized complete-block design with a factorial arrangement (0, 1, 2, and 3 kg B and 0, 0.1, and 0.2 kg Mo/ha) with four replications was utilized. Experimental units consisted of five plants. Fruits were harvested every other day during 20 days, starting 40 days after crop emergence. Yield data was submitted to analysis of variance. Significant B and Mo rate interactions were found. Maximum zucchini yields were achieved when the combination of 1.5 kg B and 0.1 kg Mo/ha was applied. Combinations containing 3 kg B/ha were toxic to zucchini, reducing yields in nearly 20% as compared to untreated plants.
