“…64, No. 1 (2024) 50 Nitrogen is a primary plant nutrient required in substantial amounts, and the particular quantity of nitrogen needed by every crop relies considerably on the species of the crop and the conditions of the soil (El-Morsy et al, 2016;Moursy et al, 2019). Because amino acids are converted into proteins, which are subsequently utilized in metabolic actions necessary for plant development (Abdissa et al 2011), the administration of the nitrogen fertilizer considerably increased onion height in comparison with the control.…”

O EXPLORE the influence of varied nitrogen rates and foliar spraying of natural stimulants on vegetative growth, yield, and onion quality. This experiment was carried out over the two seasons 2019-2020 and 2020-2021 to investigate nitrogen fertilizer at rates: 144, 216, and 288 kg N ha -1 and natural stimulant treatments (yeast extract, fulvic acid, amino acids, and seaweed extract). As well as control. The results clearly demonstrated that raising the nitrogen rate from 144 to 288 kg N ha -1 significantly enhanced the leaves number of plant -1 , fresh plant weight (g), average bulb weight (g), marketable bulb yield (t ha-1), double bulbs%, bulb diameter, TSS%, dry matter%, N%, P%, K%, carbohydrate% and protein content%. Foliar spraying with natural stimulators (yeast extract, fulvic acid, amino acids, seaweed extract) significantly increased plant height (cm), number of leaves/plant, fresh plant weight (g), neck diameter (cm), bulb diameter (cm), bulbing ratio, average bulb weight (g), marketable bulb yield (t ha-1), culls bulb yield (t ha-1), double bulbs%, bulb diameter, TSS%, dry matter%, N%, P%, K%, carbohydrate% and protein content%, during both seasons. The nitrogen at rate of 288 kg N ha -1 combined with amino acids spraying appeared the highest mean values of average bulb weight (g) during the 1 st season and marketable yield during the two seasons. The highest value of dry matter% was achieved by fertilizing by 216 kg N ha -1 when spraying with fulvic acids during both seasons.

“…Green tops and bulbs are a popular spice with a strong flavor (Verma et al, 2023), offering medical benefits like avoidance and treatment of diabetes, cancer, ulcers, rheumatism, worms, bacteria, and fungal infections (Çorbacı, 2022). Garlic needs sufficient moisture for proper establishment, growth, development, bulb production, and bulb quality (Moursy et al, 2019). The moisture content of the soil significantly influences garlic's growth, development, and yield.…”

UE to the limited water supply and rising food demand, studying how applied irrigation rates affect crops at this critical time due to climate change is essential. Therefore, an experiment was carried out to examine the effect of different irrigation water rates, specifically 60, 80, 100, and 120 of the water requirements (WR), on the growth, bulb yield properties, and water status of garlic (Allium sativum L.) clone Sids-40. The data was recorded after 80 -140 days from planting, where polynomial regression analysis was estimated between the growth stages and growth parameters. Similarly, 100% of the WR considerably increases plant height, leaf number, leaf fresh weight, and growth attributes like absolute growth rate, specific leaf area, leaf area index, chlorophyll a, b, and total carotenoids contents. While the irrigation at a rate of 60% WR led to an intrinsic rise in leaf water saturation deficit, proline content, and ascorbic acid content. Bulb parameters such as weight, diameter, and number of cloves per bulb, besides yield quantity with bulb grade one G1 (above 5.5 cm), pyruvic acid as pungency, and dry matter contents were determined to be at their highest values with irrigation at 100% of the WR. A 60% of the WR water shortage represented the high yield reduction with grade 4 (less than 3.5 cm). Pearson's correlation revealed positive relationships between bulb yield, characteristics, and growth attributes. Hence, garlic plants respond to irrigation at 100% of the WR by improving their morpho-physiological, productivity and bulb quality.

“…Low N inputs induce metabolic imbalance within plants and, also, limits the synthesis of amino acids and proteins, thereby affect negatively on photosynthesis, growth, and chemical composition of the plant tissue (Liao et al, 2019). This may lessen plant growth especially in early growth stage and, also, delay flowering (Burns, 1996 andMoursy et al, 2019). Thus, timing and the dose of N-application may have direct impacts on fruit yield quantity and quality (Heidari and Mohammad, 2012).…”

T HIS study aims to investigate the effect of different nitrogen concentrations (60, 120 and 180 mg L -1 ) applied in the form of ammonium nitrate (NH 4 NO 3 ) through fertigation and, also, phosphorus concentrations (15, 35 and 55 mg L -1 ) in the form of phosphoric acid (H 3 PO 4 ), individually or in combination with each other,on the growth parameters and yield of lettuce plants (Lactuca sativa L.), as well as nitrate accumulation in plant tissues. The investigations were conducted under the field conditions during the two growing seasons of 2019/2020 and 2020/2021 at the experimental farm of Dokki site, Giza Governorate, Egypt, following a split plot design. Obtained results indicated that increasing N supplies up to 180 mg L -1 led to concurrent increase in the vegetative growth characters (i.e., plant height, stem diameter, number of leaves per plant and chlorophyll content) of lettuce plants. While the lowest growth and productivity of plants were obtained by applying 60 mg N L -1 . Regarding the effects of P additions, increasing P supply up to 55 mg L -1 increased the growth and productivity of plants during both studied seasons. Interaction effect between N and P levels indicated that 180 mg N L -1 combined with 55 mg P L -1 gave the highest lettuce productivity followed by 180 mg N L -1 combined with 35 mg P L -1 . The weight of lettuce head took the same trend of vegetative growth. The chemical analyses revealed that increase N dose led to increase the content of N, K, Ca and Mg as well as N-NO 3 in plant tissues. Increase P level led to increase the P content. Finally, increase P level led to decrease N-NO 3 and transformation rate of nitrate in plant tissues.
