The study was conducted to determine the effect of pre harvest spray of micronutrients like boron, zinc and its combination on post harvest quality and vase life of carnation. Post harvest quality of flowers like flower stalk length (65.61 cm) was maximum in the plant treated with zinc (0.3 per cent), and calyx splitting (3.12 per cent) was minimum in the plants treated with boron (0.1 per cent). Flower diameter (6.64 cm) was highest with boron (0.1 per cent) + zinc (0.3 per cent) treatment. Plants without micronutrient treatment produced poor quality flowers. Regarding vase life studies maximum water uptake and minimum transpiration loss from first day to sixteenth day was resulted in the flowers which are obtained from the plant treated with boron (0.1 per cent). The maximum fresh weight of the flower was noticed in combination of boron (0.1 per cent) + zinc (0.3 per cent) from first to sixteenth day. The foliar spray of boron (0.1 per cent) recorded maximum vase life (11.05 days). So the good quality of flowers can be improved by the foliar spray of zinc, calyx splitting can be controlled by boron foliar spray and vase life of the flower can be maintained by foliar spray of boron. It is confirmed that the foliar application of micronutrient is very much helpful for the improvement of post harvest quality and vase life of carnation.

Investigations were conducted to study the effect of different polyamines and natural growth substances as a pre harvest foliar spray on greenhouse rose cv. Samurai. The study involved preharvest foliar spraying with polyamines like spermine (10 ppm) and spermidine (10 ppm); natural growth substances like enriched banana pseudostem sap (1 per cent) and cow urine (2 per cent). All the treatments improved the vegetative and flowering characters over control. However, among different treatments, foliar spray of spermine 10 ppm, followed by spermidine 10 ppm were highly significant in influencing all vegetative parameters like plant height (79 cm), number of branches per plant (3.73), stem girth (10.69 mm), number of leaves per plant (91.33), leaf area (14.68 cm2) and leaf chlorophyll content (36.96 mg/g). Further, flowering parameters like flower stalk length (61.24cm), bud length (2.70mm), flower diameter (6.50 cm), number of petals per flower (55.90) and vase life (6.63 days) were significantly maximum in plants sprayed with spermine 10ppm. The treatment of foliar spray with spermine and spermidine almost doubled the flower production and improved the flower quality in tems of bud size and vase life as compared to control.

An investigation was carried out to study the effect of post harvest treatments and harvesting stage on vase life and flower quality of cut Oriental lily cv. Avocado. The results showed that highest vase life (15.83 days) and vase solution uptake (49.17 ml) was recorded with sucrose (2%) + 5-SSA (200ppm), whereas maximum flower diameter (15.17 cm) was recorded in vase solution containing sucrose (2%) + 5-SSA (100ppm). Earliest opening of florets (4.42 days) reported under sucrose (2%) + 5-SSA (200ppm). Effect of treatments was found non-significant in respect to opening of florets. Harvesting at green bud stage exhibited extended vase life (14.33 days) and higher vase solution uptake (40.43 ml), whereas maximum flower diameter (14.25 cm) recorded at 75% colour development stage. Based on the results it is concluded that 5-SSA could be an inexpensive and potential chemical for delaying senescence and for extending the keeping quality of cut liliums commercially.

Heat stress during reproductive and grain filling phases adversely affects the growth of cereals through reduction in grain’s number and size. However, exogenous application of antioxidants, plant growth regulators and osmoprotectants may be helpful to minimize these heat induced yield losses in cereals. This two year study was conducted to evaluate the role of exogenous application of ascorbic acid (AsA), salicylic acid (SA) and hydrogen peroxide (H2O2) applied through seed priming or foliar spray on biochemical, physiological, morphological and yield related traits, grain yield and quality of late spring sown hybrid maize. The experiment was conducted in the spring season of 2007 and 2008. We observed that application of AsA, SA and H2O2 applied through seed priming or foliar spray improved the physiological, biochemical, morphological and yield related traits, grain yield and grain quality of late spring sown maize in both years. In both years, we observed higher superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) activity in the plants where AsA, SA and H2O2were applied through seed priming or foliar spray than control. Membrane stability index (MSI), relative water contents (RWC), chlorophyll contents, grain yield and grain oil contents were also improved by exogenous application of AsA, SA and H2O2 in both years. Seed priming of AsA, SA and H2O2was equally effective as the foliar application. In conclusion, seed priming with AsA, SA and H2O2 may be opted to lessen the heat induced yield losses in late sown spring hybrid maize. Heat tolerance induced by ASA, SA and H2O2 may be attributed to increase in antioxidant activities and MSI which maintained RWC and chlorophyll contents in maize resulting in better grain yield in heat stress conditions.

Aim: To determine the impact of soil and foliar application of ZnSO4.7H2O at late stages of wheat as heading initiation (5% ear formation), 100% heading (complete ear formation) and heading initiation and 100% heading along with recommended dose of fertilizer on growth, yield and quality of zero till wheat. Methodology: The field experiment was conducted on zero till wheat. The treatments consisted of control (no Zn), soil application of 12.5, 25, 37.5, 50 kg ha-1 ZnSO4.7H2O and foliar application of 0.5% Zn as one spray at heading initiation (5% ear formation), one spray at 100% heading (complete ear formation) and two sprays at heading initiation and 100% heading with recommended dose of fertilizer. These treatments were evaluated in RBD with three replications. Results: Soil application of 50, 37.5 and 25 kg Zn ha-1 with two foliar sprays of 0.5% at heading initiation (5% ear formation) and 100% heading (complete ear formation) stages gave significantly higher average grain and straw yield and Zn concentration in grain than other treatments, including control. Interpretation: Enhanced application of Zn as soil and foliar application ameliorates soil Zn deficiency and increases protein content in grains, which might influence the quality and yield of zero tilled wheat.

Abstract The study was conducted in one of the private orchards in the Saqlawiya area - Fallujah during the 2020 growing season. The foliar spray was used to study the effect of the timing of foliar spraying (three sprays, the first at the beginning of flowering, second at the stage of full flowers blooming, and the third at the stage of petal fall), Presented with symbols (D1, D2 and D3), respectively. The second factor consisted of spraying with boron and zinc with the following concentrations (0,1, and 3 gm. L-1), mentioned as (S0, S1, S2, S3), respectively. these elements were used singly or in the form of a mixture with the same concentrations. This study aims to study the effect of the two factors on the growth and setting of apple trees, cv. Ibrahimi. Therefore, (36) five-year-old apple trees with homogeneous vegetative growth were selected as much as possible. The results revealed that foliar application with boron and zinc for the Ibrahimi apple trees improved the quality of the fruits and their vegetative and flowering traits. The results revealed that spraying with micronutrients at the stage of petal fall had a significant effect on flower traits and yield especially the media culture (M3) which presented the best results for the traits. The results revealed that spraying with micronutrients at the stage of petal fall had a significant effect on flower traits and yield especially the time (D3) which presented the best results for the traits (leaf area, Rate of increase in the length of the branches, Rate of increase in branch diameters, Fruits set Percentage, Percentage of fallen fruits and Percentage of remaining fruits, which reached (24.25cm2, 56.77cm, 0.42cm, 26.65%, 45.25%, 54.75%), respectively. On the other hand, spraying with micronutrients achieved significant effect, especially (S3), that gave the highest values for the traits (Rate of increase in branch diameters, Fruits set Percentage, Percentage of fallen fruits and Percentage of remaining fruits), which were (37.50 cm, 0.42%, 26.65%, and 46.71 gm L-1).

Abstract Phyto-hormones play a key role in regulating plant responses to stress. Cytokines are a type of phyto-hormones involved in the regulation of many important biological processes related to growth, development, and response to environmental variables. The exogenous application of cytokines increases the possibility of delaying senescence; however, this is a physiological process, and, under certain conditions, degradation processes may be triggered. The effect of 6-bencilaminopurine application and the endogenous hormonal changes involved in lilies floral stalks after their cutting were studied. In order to improve vase life and quality of Lilium longiflorum ‘Brindisi’ flower stalks, they were sprayed with 6-BAP, at a concentration of 300 ppm at pre-harvest, post-harvest, and pre- and post-harvest stages. After that, they were compared to non-sprayed control stalks. The application of 6-BAP caused endogenous hormonal changes in abscisic acid and cytokinin levels, and the most effective treatment was pre-harvest spraying. This treatment proved to be an appropriate method to improve the stalk tolerance to post-harvest stress as it delayed the appearance of senescence symptoms and reduced the speed of chlorophyll degradation with differences of up to 10% with respect to untreated stalks. In addition, the opening of flowers was delayed by up to 2 days, although there were no significant differences in total vase life.

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.
