The pot experiment was carried out during two successive seasons (2016/2017 & 2017/2018) to study the effect of five levels of salinity and three levels of silicon (Si), as a foliar-spray application as well as their combinations on growth, productivity and chemical constituents of chia (Salvia hispanica L.) plants. Results showed that there was a negative relationship between vegetative growth measurements i.e., plant height, fresh weight and dry weight, flowering growth and yield parameters i.e., main inflorescence height, main inflorescence weight, inflorescences weight, seeds weights, weight of 1000 seeds and calculated seeds yield /m2 and root growth measurements i.e. root length, root weight and root diameter values and salinity treatments in both seasons. Hence, as the concentrations of salinity increased, the values of these parameters decreased to reach the maximum decreasing at the high concentration (4.69 dS m-1). Therefore, the combination treatment between 0.68 dS m-1 salinity concentration and 2000 ppm silicon scored the highest values of these parameters, in the 1st and 2nd seasons. Meanwhile, the maximum values of N, P and K contents were recorded by the combination treatment between 0.68 dS m-1 salinity concentration and 2000 ppm silicon in both seasons. Whereas, the highest values of free proline, sodium and chloride content were gained by the high concentration of salinity 4.96 dS m-1 especially those received silicon at 0 ppm in both seasons. Conclusively, the highest growth, productivity and chemical constituents of chia (Salvia hispanica L.) plant, it is preferable to grow the plants under saline water irrigation concentration at (0.68 dS m-1) and spray with silicon at 2000 ppm.

Field experiment was conducted in Giza, Egypt, during two growing seasons of 2017-2018 and 2018-2019 on garlic crop, with the objective of investigating the effect of different irrigation levels (60, 80 and 100 % of water requirements and their combination with the foliar spraying applications of agrispon (with 0.5 and 1.0 ml/ liter) on growth and yield. The results indicated that increased irrigation level up to 100% led to increased vegetative characters of garlic and that the lowest growth and productivity was obtained by 60% irrigation level. When considering spray application of agrispon; with 1.0 ml/L increased growth and productivity followed by 0.5 ml/L; while control treatment gave the lowest productivity during the both seasons. Interaction effect between irrigation level and agrispon treatments indicated that 100% irrigation level combined with 1.0 ml/L spray application of agrispon gave the highest garlic productivity followed by 100% irrigation level combined with 0.5 ml/L spray application. The chemical analysis showed that the highest NPK was obtained by 100% irrigation level combined with 1.0 ml/L agrispon application during the both seasons. Regarding water footprint, the highest irrigation water footprint was obtained by 80% irrigation level followed by 60% irrigation level, while the lowest footprint was obtained by 100% irrigation level due to high garlic productivity under 100% irrigation level. The estimate water footprint for garlic was 525 m3/ton. The blue water footprint for garlic was 422 m3/ton about 80% form total water footprint, while gray water percentage about 20% with value of 103 m3/ton.

Set Up

The demand for sources of nutraceuticals has led to the rediscovery and diffusion of traditional crops such as chia (<em>Salvia hispanica</em> L.), whose leaves and fruits are rich in W3 fatty acids and anti-oxidants. Chia originates in Central America but it is rapidly expanding to new areas. A field experiment conducted at Atella in Basilicata (Southern Italy) was set up to test the response of chia to N top-dress fertilisation (0 and 20 kg ha<sup>–1</sup>) and to sowing density (D1=125, D2=25, D3=8 and D4=4 plants m<sup>–2</sup>) in a split-plot design with three replications. First results show maximum leaf area index values up to 7.1 and fresh vegetative biomass production at early flowering ranging between 50.87 (D4) and 59.71 (D1) t ha<sup>–1</sup>. Yield increased with plant density: a significantly (P&lt;0.01) higher production (398 kg ha<sup>–1</sup>) was reached in D1. N top-dressing had a detrimental effect on yield and corresponded to higher lodging and lower maturation percentage of seeds, though non-significant. Based on our first results it seems worthwhile to continue agronomical trials for chia in herbaceous systems of southern Italy for leaf production based on traditional genotypes, while fruit production might be pursued by adopting high sowing density and the search for longer-day genotypes.

An experiment was conducted at the research field of the Department of Agricultural Botany, Patuakhali Science and Technology University, Patuakhali under the Agro-ecological zone-13 (AEZ-13) during the period from November 2012 to February 2013. The aim of the study was to identify the most effective irrigation level for obtaining the better growth and higher yield performance of BARI Gom-25 that are suitable to cultivate under  coastal region of Patuakhali, Bangladesh. So, the present study was consists of five irrigations levels including control viz. control or no irrigation (T0), one irrigation at 25 DAS (T1), two irrigations at 25 and 40 DAS (T2), three irrigations at 25, 40 and 55 DAS (T3)  and four irrigations at 25, 40, 55 and 70 DAS (T4). The seeds of BARI Gom-25 were collected from the BARI, Joydebpur, Gazipur on 22 November, 2012. The experiment was laid out in completely randomized block design (RCBD) with four replications and analysis was done by the MSTAT-C package program where means were separated by DMRT at 5% level of probability. Data were recorded on various growth and yield attributing traits. The plot size was 5 m2 (2.5 × 2.0 m) where row to row and seed to seed distances were 20 and 10 cm respectively. Data were collected on various morpho-physiological growth, yield and yield attributing traits. Results obtained from the present study, whole characters of the study were significant at 5% by the moisture (irrigation) levels where three irrigations given at 25, 40 and 55 DAS had most effective than that of other moisture levels and no irrigation. From the results investigation, it was found that the tallest plant (76.86 cm), maximum requiring days to anthesis (61.00 days), maturity (109.0 days) and maximum number of effective tillers (5.00 hill-1),the highest grain growth (3.11g at 36 DAA) and grains (44.00 spike-1) were obtained with three irrigation (T3) levels. Similarly, T3 further showed the greater performance on spike length (17.28 cm), 1000-seed weight (50.16 g), grain (4.16 t ha-1), straw (5.89 t ha-1) and biological yield (10.05 t ha-1) as well as the higher harvest index (41.39%). Investigated above whole characters were produced lower performances under no moisture (irrigation) treatments. These results indicated that irrigation at three times (T3) would be most advantageous irrigation levels for wheat production under the studied non saline ecosystem of coastal region.Progressive Agriculture 29 (2): 99-106, 2018

Drip irrigation technique has proved its superiority over other methods of irrigation due to direct application of water and nutrient in the vicinity of root zone. A field study was conducted to evaluate the effect of irrigation and fertigation scheduling through drip irrigation in tomato (Solanum lycopersicum L.) during Rabi season of 2015-16 at Rajasthan College of Agriculture, MPUAT, Udaipur. There were three irrigation levels and five fertilization levels in split-plot design with three replications. Nutrient content in plant and fruit was found higher under the application of drip irrigation at 100 % PE (I1) and at 100 % RDF through fertigation (F1). Maximum nutrient uptake by tomato i.e. nitrogen (166.83 kg ha-1), phosphorus (41.59 kg ha-1) and potassium (183.08 kg ha-1) was recorded with treatment combination of drip irrigation at 75 % PE (I2) + 75 % RDF through fertigation + 2 foliar spray of 1 % urea phosphate (F3). Similarly, significantly maximum yield and growth attributes i.e. fruit yield (201.25 q ha-1), plant height (67.43 cm) and number of branches (12.33) were registered with treatment combination of drip irrigation at 75 % PE and 75 % RDF through fertigation + 2 foliar spray of 1 % urea phosphate. Drip fertigation method has proved to be very significant in improving nutrient uptake which finally resulting in enhancement of growth and yield of tomato crop.

Abstract Conventional Zinc (Zn) fertilization (e.g., zinc sulfate) often leads to poor availability in soils. Zinc oxide nanoparticles (nano ZnO) can be a potential solution, but their effect on crop photosynthetic activity isn’t well documented. The effects of nano ZnO (50, 100, 150, 200 mg L-1) and application methods (seed-coating, soil-drench, and foliar-spray) in comparison with ZnSO4 recommended dose were evaluated for plant height, biomass, chlorophyll pigments and photosystem efficiency in a greenhouse pot experiment. 100 mg L-1 of nano ZnO significantly increased the chlorophyll (Chl.) a, b, a+b, carotenoids (x+c), a+b/x+c, SPAD, leaf Chl., total chlorophyll content plant-1, plant height and total biological yield (by 18-30%, 33-67%, 22-38%, 14-21%, 14-27%, 12-19%, 12-23% 58-99%, 6-11% and 16-20%, respectively) and reduced Chl. a/b (by 6-22%) over the other treatments (p<0.01) irrespective of application methods. Nano ZnO applied at 100 mg L-1 significantly increased photochemical quenching (qP) and efficiency of photosystem II (EPSII) compared to 150 and 200 mg L-1 regardless of application methods. The positive correlations between Chl. a and Chl. b (r2 0.90), Chl. a+b and x+c (r2=0.71), SPAD and Chl. a (r2=0.90), SPAD and Chl. b (r2=0.94) and SPAD and Chl. a+b (r2=0.93) indicates a uniform enhancement in chlorophyll pigments; SPAD value, qP, EPSII, and growth and yield parameters. This elucidates that the application of nano ZnO at 100 mg L-1 promotes corn biochemical health and photosynthesis, irrespective of the application method. These findings have a great propounding for improving plant growth through nano ZnO bio-fortification in acidic Spodosols.
