Abstract The experiment was conducted in the Department of Horticulture, College of Agriculture, Tikrit University for the agricultural season 2020. Two factors were studied: first; foliar application of glutamic acid at three levels (0.100,200) mg.L-1 and the second; nano zinc oxide at four levels (0,0,50,1,1050) mg.L-1 in Randomized Complete Block Design ( RCDB) with three replication. The interaction A2Z3 treatment (glutamic acid 200 mg. L-1 + nano zinc oxide 1.50 g.L-1) was achieved the highest values of a-Pinene, limonene, Linalool and Myrcene Terpinen which reached (31.4, 20.3, 22.4, 27.4 and 28.2 mg.L-1) respectively, compared to the control treatment. Whereas the interaction treatment A2Z2 (glutamic acid 200 mg.L-1 + nano zinc oxide 1 g.L-1) achieved the highest values of Camphene (35.6 mg. L-1). While the interaction of A2Z3 (glutamic acid 200 mg.L-1 + nano-zinc oxide 1.50 g.L-1) was recorded the highest concentration of Rutin and Caryophyllene, which reached (40.1 - 253.8 μg.ml-1 ) respectively, While the interaction treatment A1Z3 (glutamic acid 100 mg.L-1 + nano zinc oxide 1.50 g.L-1) was achieved the highest value of Qurcetine (192.9 μg.ml-1).

In order to study the effects of bio fertilizers and zinc fertilizer on antioxidant enzymes activity, chlorophyll content, soluble sugars and proline in triticale under salinity condition, a factorial experiment was conducted based on randomized complete block design with three replications under greenhouse condition. Experiment factors were included salinity in four levels [no-salt (control or S0), salinity 20 (S1), 40 (S2) and 60 (S3) mM NaCl) equivalent of 1.85, 3.7 and 5.55 dS m−1 respectively], four bio fertilizers levels (no bio fertilizer (F0), application of mycorrhiza (F1), PGPR (F2), both application PGPR and mycorrhiza (F3) and three nano zinc oxide levels (without nano zinc oxide as control (Zn0), application of  0.4 (Zn1) and 0.8 (Zn2) g lit-1). Results showed that salinity severe stress (60 mM) decreased chlorophyll a, chlorophyll b, total chlorophyll, carotenoid and grain yield of triticale, whereas soluble sugars and proline content, the activities of Catalase (CAT), Peroxidase (POD) Polyphenol Oxidase (PPO) enzymes increased. Results showed that both application of bio fertilizer and 0.8 g lit-1 nano zinc oxide (F3Zn2) increased about 39% from grain yield in comparison with F0Zn0 under the highest salinity level. Based on the results, it was concluded that bio fertilizers and nano zinc oxide application can be recommended for profitable triticale production under salinity condition.

An experiment was conducted to find out the combined effect of cowdung and potassium on the growth and yield of onion cv. BARI piaz-I at Horticulture Farm, Bangladesh Agricultural University, Mymensingh during the period from December 2010 to March 2011. The experiment was laid out in a randomized complete block design with three replications. The two factors experiment had four levels of cowdung, viz., 0, 5, 10 and 20 tons ha-1 and four levels of potassium, viz. 0, 50, 150 and 250 kg K ha-1. Doses of cowdung and potassium showed significant variation in respect of all the parameters studied. The combination of 10 tons cowdung and 250 kg K ha-1 gave the tallest plant (46.60 cm), the highest number of leaves plant-1 (6.40), the highest length of bulb (3.27 cm), the highest diameter of bulb (4.83 cm), individual weight of bulb (51.23 g), dry matter content (12.66%) and yield of bulb ha-1 (12.83 tons); whereas the control treatment gave the shortest plant (38.15 cm), lowest number of leaves plant-1 (5.68), diameter of bulb (3.41), individual weight of bulb (35.65g) and gave lowest bulb yield ha-1 (9.16 tons).

Substrate Types

Vermicompost (VC) samples were prepared from manure and spent mushroom compost (SMC) and were impregnated with zinc oxide nanoparticles (ZnO NPs), giving ZnO NPs/VC complexes that were added into the soil in which wax beans (Vigna unguiculata L.) were then planted. The study was carried out through a factorial experiment in a randomized complete block design with three factors. The experimental factors included: ZnO NPs (0, 0.4, 0.8 and 1.2 mg kg-1), two substrate types (cow manure and SMC) and VC (2.5, 5 and 7.5 weight percentages). To the substrate types, adult earthworms (Eisenia fetida) were added. Specifically, after three months, the prepared VC was soaked in ZnO NPs solutions, mixed with soil (according to cultivation substrate weight), then employed in wet plantation of wax beans. The obtained results showed that with increasing ZnO NPs, leaves’ chlorophyll, grains number per pod, stem length, hundred grains weight, grain yield, and the grain protein content significantly decreased. In general, the usage of these NPs in the applied amounts could curb the undesired growth of this species.

Basic Strength

The use of metal oxides in heterogeneous base catalysis has gained a large interest due to their application in many chemical and industrial processes and is environmental friendly. Basic metal oxides are commonly used and their structures, morphology and performance can be modified by method of preparation and thermal activation. In this study, surface modified amphoteric zinc oxide was prepared via hydration-dehydration method and characterised by TGA and FTIR. The basic strength at various temperatures is characterised by FTIR and back titration analyses. The results shows that surface modified zinc oxide has the highest basic strength of 1.453mmolg-1at 400°C making it a relatively good and suitable compound for use in heterogeneous basic catalysis. This result is also supported by FTIR spectra which show possible relationship between the Lewis O2-and increasing basic strength.
