ABSTRACT<br /><br />Increased of plant productivity in field determined by the use of quality seed from improved variety. The purpose of this research was to study the effect of frequency and volume of phyllosphere biological agents by foliar spray on rice plant infected by Xanthomonas oryzae pv. oryzae (Xoo) in improving plant growth, production of rice seed, and controlling bacterial leaf blight (BLB). This research was conducted at Seed Health Laboratory, Department of Agronomy and Horticulture, Bogor Agricultural University, and Muara Experimental Field, Rice Research Institute, March through September 2014. The experiment was conducted using a randomized complete block design with two factors, and replicates as blocks. The first factor was five levels of frequency of spraying with biological agents: P0 = control, P1 = Xoo seed inoculated then invigorated with biomatriconditioning, P2 = Xoo inoculated seed, then biomatriconditioned, and the plants were sprayed with phyllosphere biological agents F112 once, P3 = as P2, and the plants were sprayed with F112 twice, and P4 = as P2, and the plants were sprayed with F112 three times. The second factor was three levels of spray volume: i.e., 300, 400, and 500 L ha-1. Result of this experiment revealed that biomatriconditioning with rhizobacteria P. diminuta A6 and B. subtilis 5/B improved field emergence and seedling dry weight. Seeds applied with biomatriconditioning then followed by foliar spray with phyllosphere bacteria F112 at 40, 60, and 80 days after transplanting effectively reduced severity of BLB, increased plant dry weight and seed yield. All treatments increased yield as compared to untreated control. Volume of foliar application showed no significant difference, therefore, the lowest volume of 300 L ha-1 was recommended. <br /><br />Keywords: Bacillus subtilis 5/B, biomatriconditioning, Pseudomonas diminuta A6, Xanthomonas oryzae pv. oryzae

Improved soil fertility is a requirement for enhanced crop production. Combination of inorganic and organic fertilizers improve crop productivity while reduce environmental degradation. An experiment was carried out at Eastern University, Sri Lanka to study the effect of Foliar Application of Banana Pseudostem Sap on Yield of Cowpea (Vigna unguiculata L. Walp.) in sandy regosol. The experiment was laid out in Randomized Complete Block Design having five treatments viz; recommended inorganic fertilizer N, P, K as basal and N as topdressing (T1), N, P, 1⁄2 K as basal with recommended N as topdressing and foliar spray of 1% , 3%, 5% and 7% banana pseudostem sap solution (T2-T5) at 3rd, 5th, 7th and 9th week after planting. The results revealed that significant difference (P<0.05) were noted on number of pods per plant at 1st and 2nd picking. Higher number of pods per plant, maximum pod length and girth were in T2 while low in T1. Sun dried weights of pods and number of seeds per pod were significantly (P<0.05) varied at each picking. Further, cowpea yield at each picking were higher in T2 compared to tested treatments. The present study suggested that, among the tested treatments N, P, 1⁄2 K as basal with recommended N as topdressing and foliar spray of 1% Pseudostem sap solution at 3rd, 5th, 7th and 9th WAP would be the most suitable for cowpea production in sandy regosol.

Field experiments were conducted in the Dominican Republic to determine the effect of combinations of N with folcysteine and gibberellic acid 3 on cilantro (Coriandrum sativum) yield. Nitrogen levels (0, 36, 55, 73, 91 kg·ha–1) in soil application at sowing were combined with foliar spray of the biostimulant folcysteine or gibberellic acid (0, 100, 200, 300, and 400 ppm) 15 days after emergence. Treatments were applied in a factorial arrangement on a randomized complete block design with three replications. Fresh weight of the aerial part of the plants was determined 40 days after emergence. No significant difference was found due to folcysteine treatment. Nitrogen had a significant effect, with optimal yield at 55 kg·ha–1. Significant interaction was detected for the combinations of gibberellic acid and N, with yield increasing as the rate of the two factors increased.

Promotive Effect

The effect of foliar ALA application on the internal ALA concentration in tomato plants grown in soil containing high levels of NaCl  was investigated. Six week old plants were treated with 100, 50, and 25 mmol/L NaCl on a weekly basis and they were simultaneously treated with 5-ALA at a concentration of 5%  by foliar spray. The effect of foliar ALA application on plant growth, chlorophyll contents and internal ALA concentration was studied. The internal ALA shoot concentrations ranged between 27.50±2.12 and 34.35±1.48 µg g-1 dry weight with no significant difference (p<0.05) recorded between plants treated with NaCl alone and those treated with both NaCl and ALA. The concentrations of chlorophyll a and b were elevated only in tomato plants treated with NaCl and ALA, whereas their levels decreased in plants treated with NaCl only. An adverse significant effect (p<0.05) of salinity stress was recorded on plants length, number of leaves, shoot and root fresh and dry weight. However, no significant difference  (p<0.05) was observed in plants treated with  NaCl alone with those treated with  NaCl plus ALA in comparison to the control. The results of the present study suggested that foliar ALA treatment had no effect on the Na and Cl uptake, the internal ALA concentration, and had no role in adverting the effects of salinity on plant growth. The present study has proven that foliar ALA is directly used by the plant for the synthesis of chlorophyll in order to increase the photosynthetic rate and thus to help tomato plants to survive the salinity stress.

Salicylic acid (SA) is a common plant-produced signal molecule that is responsible for inducing tolerance to a number of biotic and abiotic stresses. An experiment was, therefore, conducted to test whether acetyl salicylic acid (ASA) application at various concentrations through seed immersion or foliar spray would protect muskmelon [Cucumis melo L. (Reticulatus Group)] seedlings subjected to chilling stress. Twenty-one-day-old plants pre-treated with ASA (0, 0.1, 0.25, 0.50 or 1.0 mM) were subjected to chilling stress for 72 h at 3 ± 0.5°C. ASA, applied either through seed immersion or foliar spray, was effective within the range of 0.1 to 1 mM in inducing tolerance to chilling stress in muskmelon seedlings; however, there was no significant difference between application methods. ASA significantly and curvilinearly affected all seedling growth and stress indicator variables tested except shoot dry weight. The best protection was obtained from seedlings pre-treated with 0.5 mM ASA. The highest ASA concentration used was slightly less effective in providing chilling stress protection. Even though both methods provided similar means of protection, due to its simplicity and practicality, immersion of muskmelon seeds prior to sowing in 0.5 mM ASA would be a more desirable method to induce tolerance to chilling stress.

Two pots experiments were conducted at the Experimental Farm of El-Qassasin Horticultural Research Station, Agricultural Research Center, Ismailia Governorate, Egypt, during two successive seasons of 2016/2017 – 2017/2018, to investigate the effect of potassium silicate at (0, 4, 6, and 8 cm3/l) as a foliar spray under different levels of water salinity (tap water, 1000, 2000 and 3000 ppm) on Calendula officinalis L. plant. The experiment was performed in complete randomized block design as factorial experiment with 3 replicates. The obtained results cleared that using salinity levels decreased growth parameters (plant height, number of branches/plant, fresh and dry weights of herb/plant), flowering parameters (flower diameter, number of flowers/plant, fresh and dry weight of flowers (g/plant) during eight cuts and fresh and dry weight of flowers (g/plant/season)) and chemical constituents (chlorophyll a, chlorophyll b, carbohydrate and carotenoid contents) compared to control. Moreover, the highest values in these parameters were registered by potassium silicate at 8 cm3/l concentration. Proline content increased in leaves with using saline water at 3000 ppm + potassium silicate at 8 cm3/l. Generally, it could be concluded that potassium silicate at 8 cm3/l, showed a uniform impact in alleviating inhibition of Calendula officinallis L. plant growth and productivity under moderate salinity stress condition.

Dioscorea is potentially used as staple food to support food security. The research was aimed to determine the effect of stake length and time of  stem twining  on  the growth of Dioscorea sansibarensis Pax. The experiment was conducted  in  Purwodadi Botanic Garden from December 2014 until May 2015 using split plot randomized block design consisted of two factors, i.e. the stake length and time of stem twining. The stake length was the main plot consisted of 150 cm, 100 cm and 50 cm above soil surface and without stake (control). The time of stem twining as subplots, i.e. stem twined early, twined at the time of 4 leaves stage, and twined at 8 leaves stage. Each combination of the treatments was replicated three times. The results showed that there was significant effect on the stake length  and the time of stem twining treatments on the plant growth and yield. The stake  length of 150 cm treatment produced the highest fresh tuber and total plant dry weight, i.e., 257.24 g and 132.77 g per plant, respectively. On the contrary, the plant without stake produced the lowest fresh tuber and  total dry weight of plant, i.e., 112.10 g and 48.65 g per plant, respectively.<br /><br />Keywords: biomass,leaf area, photosyntesis, tuber weight
