Durum wheat has a comparative adaptive advantage over bread wheat under hot and dry conditions. Accordingly, it feeds millions of people in the Middle East and North Africa. Under these conditions, the deficiency of nutrients, including micronutrients, is a major concern for many reasons, including calcareous soil under drought stress conditions. Therefore, growth, yield, iron (Fe) and zinc (Zn) concentration in durum wheat cultivar grains were investigated. A factorial experiment based on a randomized complete block design with three replications was conducted in the Dryland Agricultural Research Institute (DARI) - Moghan. The first factor comprised spraying at four levels, including the control and foliar spraying with Fe, Zn, and Fe+Zn and the second factor consisted of genotypes at four levels: Dehdasht (G1), Seymareh (G2), and two new genotypes (G3 and G4). Solutions of Fe and Zn fertilizers were sprayed at the tillering, early ear emergence, and milk stages, with a ratio of 2 and 1.5 g fertilizer/1000 ml solution (W/V), respectively. The results showed that genotypes G1, G3 and G4 produced higher grain yield per square meter than G2. This increase was due to the higher weight of 1000 grains in G3 and G4 genotypes and 1000-grain weight with a higher grain number in G1. G1 and G2 had greater spike length, number of grains per spike and spikelet than G3 and G4 genotypes. In all studied traits, except Fe and Zn concentration, the combination of Fe+Zn showed the highest and control had the lowest performance. Also, the application of Zn was superior to Fe. The highest Fe concentration of G1, G2, G3, and G4 was observed at Fe+Zn, control, Zn, and Fe levels, respectively. The highest Zn concentrations were observed in the G3 genotype when only Zn was used or in combination with Fe. According to the results, the Fe and Zn spray application increased durum wheat yield on Fe and Zn deficient soil.

A field experiment was conducted to study the effect of different levels of potassium and zinc on growth, yield and economics of sweet potato. The experiment was laid out on clay and loam soil by adopting randomized block design with factorial technique (FRBD). The sixteen treatments consisted of combination of four levels of po-tassium (0, 80, 100 and 120 kg/ha through muriate of potash and four levels of foliar zinc (control i.e. water spray, 10, 20 and 30ppm) through zinc sulphate. The individual application of potassium 120 kg K2O/ha significantly in-creased the number of tubers per plant (4.60), average weight of tuber (275.31 g), length of tuber (16.77 cm), diam-eter of tuber (5.69 cm), tuber yield per plot (9.71 kg), tuber yield per hectare (49.04 t) respectively as compared to control. With the foliar application of zinc (30 ppm) significant increase in number of tubers per plant (4.18), average weight of tuber (234.73 g), length of tuber (18.12 cm), diameter of tuber (5.16 cm), tuber yield per plot (8.33 kg) and tuber yield per hectare (42.05 t) was recordedas compared to control. The treatment combination (120 kg K2O+30ppm Zn) recorded the maximum yield parameters i.e. chlorophyll content (37.00 mg/100 g), average weight of tuber (302.17 g), length of tuber (19.82 cm), diameter of tuber (5.97 cm), maximum tuber yield per plot (11.02 kg), tuber yield per hectare (55.67 t) and benefit-cost ratio (B: C ratio) of 4.22:1.While, the treatment (120 kg K2O+30ppm Zn) had the maximum number of tuber (4.86), minimum number of tuber was recorded in control. From the experi-ment, it appeared that application of potassium and zinc can be used to improve yield and higher net monetary re-turns of sweet potato.

Chickpea (Cicer arietinum L.) is the most important and ancient pulse crop being traditionally grown during rabi season and cultivated mainly in semi-arid regions. The content of iron and zinc in the soil of Regional Agricultural Research Station (RARS) is below the critical level. A field experiment to study the effect of iron and zinc nutrition on growth, yield and nutrient uptake by chickpea conducted in the vertisols of the Regional Agricultural Research Station (RARS), Vijayapur during rabi 2017-18. The experiment was laid out in randomized complete block design with ten treatments and three replications. The treatments included RPP (Recommended package of practice) and application of iron @ 2, 4 and 6 kg ha-1 and zinc @ 2, 3 and 4 kg ha-1 in combinations along with RPP (RDF (Recommended dose of fertilizer) @ 10:25:00:: N : P2O5 : K2O kg ha-1). The results of the experiment revealed that, the application of iron and zinc in combinations resulted in significant increase in growth, yield and nutrient uptake by chickpea over RPP alone. Among the different treatments RPP + 6 kg Fe ha-1 + 4 kg Zn ha-1 was resulted in the maximum test weight (28.28 g), seed (2065.4 kg ha-1) and straw (1734.9 kg ha-1) yield. Similarly, higher protein content, uptake of nutrients (Fe and Zn) by the crop and residual iron and zinc status in soil were recorded due to the application of RPP + 6 kg Fe ha-1 + 4 kg Zn ha-1. These results were at par with the application of RPP + 6 kg Fe ha-1 + 3 kg Zn ha-1 and lower values were recorded in the treatment that received RPP alone. Finally it could be concluded that the application of fertilizers containing iron and zinc helpeds to improve crop yield, protein content and nutrient uptake by chickpea crop and residual soil fertility in terms of iron and zinc.

A field experiment was conducted at the Plant Physiology Field of Horticulture Research Center (HRC), Bangladesh Agricultural Research Institute, Gazipur during the rabi seasons of 2015-16 and 2016-17 to study the response of cabbage (var. Krishibid Hybrid-1 and Atlas-70) to foliar application of GA3 and NAA with different concentrations. The experiment was laid out in a Randomized Complete block Design with three replications. The experiment consisted of eight treatments viz., three levels of GA3 (at 50, 75 and 100 ppm) and four levels of NAA (at 40, 60, 80 and 100 ppm) along with distilled water as control. The varieties Krishibid Hybrid-1 and Atlas-70 were used in 2015-16 and 2016-17, respectively. Foliar spray of GA3 and NAA was given at 25 and 45 days after transplanting of seedling. The results of the investigation indicated significant differences among the treatments on most of the parameters studied. In Krishibid Hybrid-1, application of 50 ppm GA3 and 60 ppm NAA increased plant height, plant spread, number of leaves, chlorophyll content, head height, head diameter, single head weight without unfolded leaves as well as head yield (81.18 t/ha for 50 ppm GA3 and 78.57 t/ha for 60 ppm NAA) than the control (67.29 t/ha) and other treatments. But, in Atlas-70, application of 75 ppm GA3 gave the maximum values of most of the growth parameters, yield components and yield (102.40 t/ha), which was followed by 50 ppm GA3 (94.96 t/ha). In Krishibid Hybrid-1, application of 60 ppm NAA gave the highest benefit-cost ratio (BCR) of 3.63 followed by 75 ppm GA3 (3.59) while in Atlas-70, 75 ppm GA3 recorded the highest BCR of 4.79 followed by 50 ppm GA3 (4.54) and 60 ppm NAA (4.37). Therefore, application of GA3 @ 50-75 ppm or NAA @ 60 ppm concentration can be recommended for increasing the yield of cabbage with higher return. Bangladesh J. Agril. Res. 44(2): 367-376, June 2019

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

Background: Thymus plants are well-known medicinal plants and it is believed that the pharmaceutical and therapeutically properties of these plants are related to their essential oils. The quality and quantity of the essential oils, as a secondary metabolite of aromatic plant, is directly related to the physiological state of the plant. The role of jasmonates in the plant as signal molecules in mediation and up-regulation of plant defense and secondary metabolism processes is well recognized. Objective: With the aim of increasing the performance and stimulating secondary metabolites, this study evaluate the influence of foliar application of MJ on essential oil content and composition of three different Thymus species, whether as an elicitor or an activator. Method: The experiment was arranged in a randomized block design with MJ treatments in four levels (0, 30, 60, 100 mM) and three replications. Results: Compared to the control, essential oil content of all three species increased in all treatment levels. However, the changes of essential oil composition were different. Under MJ treatments, the amount of sesquiterpenes (especially caryophyllene oxide) increased in T. daenensis and T. fedtschenkoi. In addition, the amount of thymol in T. daenensis, thymol, and γ-terpinene in T. vulgaris increased, whereas carvacrol methyl ether in T. daenensis and p-cymene in T. vulgaris decreased. Conclusion: It seems the type of plant species has a specific role in determining the response. There were no interpretable changes between treatment levels.

Background: Blackgram [Vigna mungo (L.) Hepper] is one of the most important cultivated legume crops with high nutritive value and agricultural importance. The productivity of blackgram is not adequate to meet the domestic demand of the growing Indian population. Consequently, there is an urgent need for enhancement of productivity through proper agronomic practices. With this background, a research experiment was conducted in a farmer’s field at Pudhupalayam, Coimbatore to investigate the effect of foliar application of PPFM, plant growth regulating compounds and nutrients on growth, yield attributes, yield and economics of irrigated blackgram. Methods: A field experiment was laid out in randomized block design with three replications during 2019 (kharif and rabi) season. The treatments include 100% recommended dose of NPK along with foliar application of diammonium phosphate (DAP), brassinolide (Br), salicylic acid (SA) and pink pigmented facultative methylotrophs (PPFM) with different concentration (1%, 2%, 1 ppm, 2 ppm, 50 ppm, 100 ppm, respectively) in addition to control. PPFM and PGRs were sprayed at 30 and 45 days after the sowing of blackgram. Result: The experiment results of the two seasons study revealed that the application of 100% RDF + PPFM @ 2% recorded higher growth characters viz., plant height (cm), number of branches plant-1, leaf area index and yield attributes viz., number of pods plant-1, number of seeds pod-1, pod weight (g), pod height (cm), 100 seed weight (g) and yield viz., grain yield (kg/ha), straw yield (kg/ha) and harvest index (%). As well as the same treatment recorded higher net return and B:C ratio. Correlation and regression analysis also indicated that the yield attributes had a positive impact on the grain yield with a magnitude of 1.91 and 1.67, respectively. Therefore, application of 100% RDF+2% PPFM spray can be recommended as the best technology to improve the yield and economics of blackgram.

The research was conducted at Research Area of Department of Agronomy, Bahauddin Zakariya University Multan, during the spring season, 2016. The study aimed to evaluate the influence of foliage applied zinc on growth, yield and oil contents of hybrid sunflower. Experimental treatments comprise of two sunflower hybrids viz. H1= Hysun-33 and H2= S-278 and three zinc levels viz. T1= Control (no application), T2=1% ZnSO4 and T3 = 2% ZnSO4. The experiment was laid out in Randomized Complete Block Design (RCBD) with split plot arrangement and repeated thrice. Data regarding growth, yield and oil contents were collected by using standard procedures. Results revealed that sunflower hybrid Hysun-33 gained maximum plant height (210.67cm), stem diameter (2.427), head diameter (15.533) achene number (852), achene yield (189.19 t ha-1), leaf area (789.56cm2) and oil contents (40.423%) followed by sunflower hybrid S-278. Zinc application significantly improved the yield and oil contents. In this regard, maximum plant height (194.67 cm), stem diameter (2.718cm), head diameter (14.633 cm), achene number (842.17), achene yield (194.56 t ha-1), leaf area (782.5cm2) and oil contents (40.12%) from 2% foliar application of zinc followed by 1% foliar application of zinc. Whereas, minimum plant height, stem diameter, head diameter, achene number, achene yield, leaf area and oil contents were recorded from control where no zinc was applied. Interaction of sunflower hybrids with zinc was also significant. In this contest, maximum plant height (231.67cm), stem diameter (2.917cm), head diameter (15.7cm), achene number (925.0), achene yield (205.89 t ha-1), leaf area (801.33cm2) and oil contents (41.65%) were recorded from sunflower hybrid Hysun-33 with 2% application of zinc followed by sunflower hybrid S-278 with 1% zinc foliar application. In Conclusion, sunflower hybrid along with the 2% foliar application of zinc is the most suitable combination to achieve higher yield and oil contents.
