The interactive responses of fertigation levels under buried straw layer on growth, physiological traits and fruit yield in tomato plant

ABSTRACT The experiments were conducted on tomato plants to study the interactive responses of water levels (W70%: 70% of water consumption and W90%: 90% water consumption) and nitrogen rates (N100%: 100% of recommended and N80%:80% of N1.0) under two straw mulching conditions (NS; no straw introduced and WS: with buried straw layer) on growth and physiological parameters for two fruit growing years to assess the interactive responses of fertigation under buried straw layer on the changes in plant fresh and dry biomass, roots biomass, photosynthesis rate (PN), stomatal conductance (GS) and chlorophyll fluorescence of tomato plants. Buried straw layer was proved to improve plant biomass, photosynthesis rate and other physiological traits such as chlorophyll contents (Chl), maximum electron transport rate (ETRmax), maximum quantum yield (FV /FM ) and GS under the lower fertilizer (N80%) and irrigation levels (W70%). However, increasing fertilizer and irrigation level decreased these parameters significantly (p < .05 to p < .001) under buried straw layer. Conversely, increased fertilizer (N100%) and irrigation (W90%) levels increased these parameters significantly (p < .05 to p < .001) under no straw condition. The overall findings revealed that buried straw layer could relieve stress developed by limited irrigation water and fertilizer and benefit plant growth, physiological parameters and fruit yield of tomato plant.

Evaluation of Poultry Waste Recycled For Vermicomposting and Its Response on Growth and Yield of Tomato Plant (Lycopersicum Esculent Mill.)

Performance of &lt;i&gt;Glomus clarum&lt;/i&gt; and &lt;i&gt;Tithonia diversifolia&lt;/i&gt; compost in improving growth and yield of tomato (&lt;i&gt;Lycopersicum esculentum&lt;/i&gt; Mill)

Screen house experiments were conducted at the Institute of Agricultural Research and Training, Ibadan, on a sandy loam soil in two years, to assess the effect of arbuscular mycorrhizal fungus ( Glomus clarum ) and compost (sunflower) on the growth and yield of tomato plants. The experimental design was laid out in a Complete Randomized Design (CRD) with nine treatments replicated three times. Arbuscular mycorrhizal fungi (AMF) and Compost (CMP) were applied into 8 kg soil each at the levels of 2.5, 5.0, 7.5 and 10 tonnes/ha each (2.5 g, 5.0 g, 7.5 g and 10 g respectively), while the control had 0 tonnes /ha (0 g). Results showed that plants treated with 5.0 tonnes/ha AMF produced highest cumulative weight of harvested fruits per plant and number of fruits per plant which were significantly higher (P<0.05) than other treatments. Application of 2.5 tonnes/ha CMP significantly (P<0.05) produced the highest number of tomato leaves per plant, while the highest number of flowers per plant was significantly higher for 7.5 tonnes/ha CMP. The tallest plants and plants with highest number of branches were also recorded for 5.0 tonnes/ha AMF. This study showed that 5.0 tonnes/ha is the optimum level of AMF required for the cultivation of tomato plant which could have arisen from optimum uptake of phosphorus in the soil.

The study was conducted to investigate efficacy of Integrated disease management (IDM) viz., solarized soil, Trichoderma harzianum, spent mushroom compost and carbendazim on growth characteristics of infected tomato by Fusarial wilt (Fusarium oxysporum f.sp. lycopersici) under pots conditions in the Bio-net house during 2013-2014. Seven treatments and five replicates were taken up in completed randomized design. Maximum shoot length, fresh and dry shoot weight were noticed in T4 (solarized soil+ Spent mushroom compost+ T. harzianum) 118.10 cm, 67.25 and 42.20 g respectively as compared to T. harzianum or spent mushroom compost that alone treated plants. Maximum root length, fresh and dry root weight were also recorded in T4 (solarized soil+ spent mushroom compost+ T. harzianum) 28.35 cm, 4.65 and 2.55 g respectively. The yield of tomato plants was significantly increased in T6 (tomato plant alone without Fusarium oxysporum) 170.15 g/plant followed by T4 137.52 g/plant as compared with T0- Fusarium oxysporum alone and T1- Solarized soil + Fusarium oxysporum 0.0 g.

Gelatin encapsulation of chloropicrin and 1,3-dichloropropene as fumigants for soilborne diseases in the greenhouse cultivation of cucumber and tomato

AbstractCombined use of chloropicrin (Pic) and 1,3-dicloropropene (1,3-D) is as effective as methyl bromide (MB) at controlling soilborne diseases in many trials and commercial uses. However, Pic and 1,3-D are both highly volatile and may pose strong exposure risks to humans and the environment. A gelatin capsule formulation containing Pic and 1,3-D has been developed to reduce exposure risks to workers and bystanders and improved application safety. We conducted two experiments in tomato and cucumber greenhouses located in Beijing and Qingdao, China, to study the efficacy of Pic plus 1,3-D gelatin capsules applied at different dosages and soil depths. Results indicated that both injection and gelatin capsules of Pic plus 1,3-D provided good control of soil nematodes and reduced disease index of Fusarium wilt and root-knot nematode. Plant yield of tomato and cucumber treated with gelatin capsules was similar to MB treatment. Based on our results, gelatin capsules applied at a soil depth of 15 cm provided better control of soilborne diseases and led to higher fruit yield compared to an application depth of 5 cm. In conclusion, a gelatin capsule of Pic plus 1,3-D is a promising and novel formulation, which not only shows good efficacy in controlling soilborne diseases, but also reduces potential exposure risks of fumigants.

Mineral composition and growth responses of tomato (Solanum lycopersicum L.) plants to irrigation with produced waters from the oil industry

ABSTRACTProduced waters are considered a byproduct from the oil industry that may contain mineral elements essential for plant nutrition, which enables them for irrigation purposes. Due to the growing demand for water for agricultural use in the world, the aim of this study was to determine the feasibility of using dilutions of fresh water and produced water derived from the gas-producing zone of Sabinas-Piedras Negras, in northern México and their effect on mineral content and allocation, growth, and yield of tomato plants. The results showed that the dilutions containing produced water reduced fruit, stem, and leaf fresh weight, and that the uptake and accumulation of minerals in plant tissues, except for sodium, was also decreased. However, plants irrigated with dilutions of produced and fresh water showed increased translocation of essential minerals from the leaves to the fruit, which partially contributed to alleviate the negative effects on fruit yield.

Exogenous Application of Salicylic Acid to Alleviate Glyphosate Stress in Solanum lycopersicum

ABSTARACTPesticides have nontarget toxicity and affect growth and yield of Tomato (Solanum lycopersicum L.). Salicylic acid (SA) acts a as plant growth regulator that supports plant defense systems. Activity of SA was studied to determine whether it reduced glyphosate toxicity and benefited growth and yield of tomato plants. Glyphosate at 0.25 mM and SA at 1 mM were applied to tomato seedlings at 20 days after sowing. Glyphosate decreased shoot and root length and fresh and dry weight of seedlings. Carotenoids, chlorophylls, and protein contents and activity of nitrate reductase were inhibited. Accumulation of sugar, proline content, and oxidative indices (H2O2, ion leakage, lipid peroxidation) was enhanced due to treatment with glyphosate. The antioxidant enzymes superoxide dismutase and guaiacol peroxidase increased; activities of catalase and ascorbate peroxidase decreased. Anthocyanin content declined and phenyl ammonia lyase enzyme activity increased. Pigment content and activities of antioxidant enzymes increased up to the level of the control. The level of glyphosate used caused phytotoxicity to tomato. Salicylic acid has the potential to overcome adverse effects caused by glyphosate if application is done before exposure.

Biochar and flyash inoculated with plant growth promoting rhizobacteria act as potential biofertilizer for luxuriant growth and yield of tomato plant

Overuse of agrochemical fertilizers alarmingly causes deterioration in soil health and soil-flora. Persistence of these agrochemicals exerts detrimental effects on environment, potentially inducing toxic effects on human health, thus pronouncing an urgent need for a safer substitute. The present study investigates the potential use of agricultural and industrial wastes as carrier materials, viz. biochar and flyash, respectively, for preparation of bioformulations (or biofertilizers) using two plant growth promoting rhizobacteria, Bacillus sp. strain A30 and Burkholderia sp. strain L2, and its effect on growth of Lycopersicon esculentum Mill. (tomato). The viability of strains was determined based on colony forming units (cfu) count of each bioformulation at an interval of 60 days for a period of 240 days. Seeds were coated with different carrier based bioformulations and pot experiment(s) were carried out to access its effects on plant growth parameters. Biochar based bioformulations showed higher cfu count and maximum viability for strain L2 (107 cfu g−1) at 240 days of storage. Maximum percentage of seed germination was also observed in biochar inoculated with strain L2. Significant (p < 0.05) increase in plant growth parameters (dry and fresh biomass, length, number of flowers) were ascertained from the pot experiment and amongst all bioformulations, biochar inoculated with strain L2 performed consistently thriving results for tomato yield. Furthermore, post-harvest study of this bioformulation treated soil improved physico-chemical properties and dehydrogenase activity as compared to pre-plantation soil status. Overall, we show that prepared biochar based bioformulation using Burkholderia sp. L2 as inoculum can tremendously enhance the productivity of tomato, soil fertility, and can also act as a sustainable substitute for chemical fertilizers. In addition, mixture of biochar and flyash inoculated with strain L2 also showed noteworthy results for the growth parameters and yield, and future studies are required to strengthen flyash utilization as carrier materials to resolve its disposal problem and waste management.

The genus Tagetes (Asteraceae) is native to Americas but some of its members (in particular T. erecta and T. patula) commonly known as marigolds were naturalized in the old world (India, North Africa and Europe) as early as in 16th century. The flowers of French marigold (Tagetes patula L.) are widely used in folk medicine, in particular for treating inflammation-related disorders. This study investigated the potential use of marigold (Tagetes patula L.) flower aqueous flower extract by spaying method on tomato plants on a weekly basis and the data of growth, yield and disease of tomato pants were observed from 10th day onwards under field condition. The marigold flower extract showed significant increase in shoot height, number of branches, number of leaves, number of buds, number of flowers and number of fruits of tomato plant, while significant reduction in various diseases of tomato plants over control at probability level ***p<0.001. The percentage of reduction of disease was calculated after the spray of marigold flower aqueous extract on plants. The marigold flower extract was found effectively in controlling canker (62.82%), early blight (61.53%), wilt (18.42%), fruit spot (27.41%), blossom end rot (50.43%) and sun scald (26.44%) in comparison to controls under field condition. The findings are in line with the bio-controlling properties of marigold preparations as bio-pesticide confirmed in growth and yield of tomato plants. Thus, marigold can contribute in reducing use of chemical pesticides and act as a good alternative to synthetic pesticides.

Обґрунтування критичних періодів росту помідора за різних способів поливу на основі аналізу ростової функції

Specifying the degree of dependency of variability of growth plant indexes on crop productivity is an urgent task which enables to determine the optimum parameters of the regulatory factors that facilitate to increase the productivity when efficiently using resources. The aim of the study was to make a mathematical model that describes the growth for tomatoes, and based on its analysis, specify critical growth phases, duration of critical periods when using different irrigation methods, and determine the degree of impact of growth indexes varying in critical growth phases on the yield of tomato plants. The growth processes were simulated using the B. Gompertzian function based on the dynamics of leaf-area duration obtained during the study of different irrigation methods in the period of 1993-2010 years at the Institute of Irrigated Agriculture of NAAS of Ukraine. The calculations of the duration of critical periods have shown that it is within the 31st day and doesn’t significantly differ by the irrigation methods. The maximum growth rates of leaf apparatus can be observed when using drip irrigation in 52 days starting from the beginning of vegetation, that is 8,7-19,1% higher than for the options with typical irrigation or micro irrigation. Accordingly, the yield when using drip irrigation is 12,8-17,9% higher when compared to the other irrigation methods. Based on the correlation and regression analysis it has been determined a close dependence between the growth rates of leaf apparatus in the critical phases of growth and productivity, which shows that in 92% of cases the variability of growth plant indexes of tomato plants in critical periods of growth is the reason of yield varying.
