Silicon (Si) and biostimulant management have been proposed techniques to reduce the impacts of abiotic stresses and to increase the productivity of several crops, however, there are still few concise results of the management of this crop. The objective of this work was to evaluate the effects of biostimulant and silicon treatments on isolated or mixed applications on mineral nutrition, yield and fiber quality of two cotton varieties. For this, an experiment was carried out in a randomized block design in the municipality of Luís Eduardo Magalhães-BA, in a 4 × 2 factorial arrangement, with four replications, in which four biostimulant treatments (control, without application; Si; biostimulant; and Si + biostimulant) were evaluated in two cotton varieties (FM 954GLT and FM 983GLT). The nutrient content of leaves, relative water content, electrolyte leakage, fiber yield, and quality were evaluated, the data collected were submitted to the F test and means were compared by Tukey at 5% probability. At the end of the experiment, it was verified that the management of Si and biostimulants increase the integrity of the cell wall, the association of Si + biostimulant increases the levels of N, Fe and Si foliar and reduces the levels of B and Mn, and do not influence on yield and fiber quality.

The objective of this study was to evaluate the productivity and quality of melon fruits as a function of the dose and time of application of biostimulant in the conditions of the semi-arid region of Paraíba. The experiment was carried out at the Federal University of Campina Grande, campus of Pombal - PB, Brazil, in a randomized block design in a 4 x 5 split plot scheme, with doses of biostimulant (0; 0.5; 1.0; 1, 5 and 2.0 L ha-1) and in the subset of the biostimulant application times (15; 20; 25 and 30 days before harvest - DAC), in four replications. Characteristics related to fruit production and quality were evaluated. There was no interaction between the factors of dose and application time of the biostimulant in any of the evaluated characteristics. Thus, the highest estimated values of number of fruits per plant, fruit mass and total melon production were obtained with the application of doses ranging from 0.9 to 1.5 L ha-1 and at the time of application it varied from 22,5 to 23.6 DAC. The content of soluble solids increased 5.5% when the biostimulant dose of 2.0 L ha-1 was used and 4.4% when the product was applied 15 days before harvest.

Aim: To evaluate the efficacy of foliar application of Ascophyllum nodosum extract, homobrassinolide, and triacontanol for improving fruit retention, yield, and quality in mango. Methodology: The experiment was laid out in a randomized block design with 10 treatments, comprising Ascophyllum nodosum extract (1000, 3000, and 5000 ppm), homobrassinolide (0.1, 0.3, and 0.5 ppm), triacontanol (1, 3, and 5 ppm), and water as control. Treatments were foliar sprayed at panicle initiation, pea, and marble stages of fruit growth. Observations were recorded on flowering, fruiting, yield, and fruit quality parameters. Results: All the treatments of Ascophyllum nodosum extract and triacontanol exhibited significant improvement in fruit retention, fruit weight, yield, and fruit quality parameters over control. However, 3000 and 5000 ppm Ascophyllum nodosum extract treatments outperformed all the treatments of triacontanol. Plants sprayed with 5000 ppm Ascophyllum nodosum extract recorded the maximum value for fruit retention (48.15, 36.74, 29.48, and 25.76% at 3, 6, 9, and 12 weeks after pea stage, respectively), number of fruits (133.25 per tree), fruit weight (188.84 g per fruit), and yield (25.16 kg per tree), whereas the lowest values were recorded under control. With respect to fruit quality, 3000 ppm ANE produced the fruits with the highest TSS (19.62 °B), whereas the highest TSS/acid ratio was recorded with 5000 ppm ANE (62.29) treatment. Interpretation: In mango, foliar application of Ascophyllum nodosum extract (3000-5000 ppm) thrice at panicle initiation, pea, and marble stages of fruit growth is effective for reducing fruit drop and enhancing quantum and quality of produce.

Fertilization Response to Off-Season Production and Fruit Quality of Salak Gula Pasir (Salacca Zalacca cv. Gula Pasir) and water and Chlorophyll Content of Leaves. Naturally salak Gula Pasir (Salacca zalacca cv. Gula Pasir) flowers every three months a year, but only one to two seasons of the flowers can develop into fruit. Failure of flowers develop into fruit, usually call fruit-set failure, causes the fruits be available seasonally in a short time period, only 2-3 months a year, i.e. during the harvest time (on-season period) from December to February. This research aimed to know response of fertilization to off-season production and fruits quality of salak Gula Pasir and its ralatinship to water and chlorophyll content of leaves. The study used a randomized block design with the treatment was fertilization, consists of 14 levels (fertilized according farmers’ way with leaf midrib only/control, fertilized with compost, mycorrhizal biofertilizer, inorganic NPK, combination of farmers' way and compost, combination of farmers’ way and mycorrhizal biofertilizer,  combination of farmers' way and inorganic NPK, combination of compost and mycorrhizal biofertilizer,  combination of compost and inorganic NPK,  combination of mycorrhizal and inorganic NPK,  combination of farmers’ way, compost, and mycorrhizal biofertilizer,  combination of farmers’ way, compost, inorganic NPK,  combination of farmers’ way, mycorrhizal biofertilizer and inorganic NPK, and  combination of farmers’ way, compost, mycorrhizal biofertilizer, and inorganic NPK). Each treatment was repeated 3 times. The study was carried out in the off season period from April to Nopember 2018 at the production center of salak Gula Pasir plantation i.e. at Sibetan Village, Bebandem District, Karangasem Regency. The results showed that the highest fruit weight per tree at the off-season was obtained on combination of fertilization of farmers' way and mycorrhizal biofertilizer  (of 2536.67 g) and the lowest was on  control/fertilized according farmers’ way  (1,220.00 g). Fertilization with compost, mycorrhizal biofertilizer, and inorganic NPK singly, or by combining it, increases the quality of off-season fruit of salak Gula Pasir, reflected by the increase of weight per fruit, fruit diameter and fruit sweetness compared to control. The lower of yield per tree and quality of fruit on control compared to other fertilization treatments was relate to low relative water content and chlorophyll content of leaves.

ABSTRACT The netted melon requires special growing conditions, including a protected environment, an adequate staking system and proper water and nutrient management. This study aimed to assess the effect of irrigation levels and silicon doses on the yield and quality of Sunrise hybrid melons, in a greenhouse. A randomized block design was used, with a 5 x 3 factorial scheme and four replications. The first factor consisted of five silicon doses (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1) and the second of three irrigation levels (40 %, 70 % and 100 % of the ETc). The results demonstrated that the applied irrigation levels and silicon doses have no influence on the yield traits of melon plants. The irrigation level corresponding to 100 % of the ETc promotes higher values for soluble solids (9.86 ºBrix) and maturation index (114.9) on fruits. The increase of silicon doses up to 200 kg ha-1 also increases the maturation index in the treatment with the greatest irrigation level and reduces this index at the shallowest level applied.

Effects of lime and gypsum applications on the quality of soybeans grown under no-till (NT) are not well defined yet. A field trial established in 1998 on a dystrophic clayey Rhodic Hapludox, at Ponta Grossa, State of Paraná, Brazil, evaluated grain yield and soybean quality based on oil, protein and nutrient content, after lime and gypsum applications under NT, in a randomized complete block design (n = 3), split-plot experiment. In the main plots, the treatments with dolomitic lime were: control (no lime), split application of lime on the surface (three yearly applications of 1.5 Mg ha¹), surface lime (4.5 Mg ha¹), and incorporated lime (4.5 Mg ha¹). Subplots received four different rates of gypsum: 0, 3, 6, and 9 Mg ha-1. The soybean crop was evaluated in the agricultural years of 20022003 and 20032004. After 58 months, the correction of acidity through surface liming, with full or split rates, was more pronounced in the top layer (00.05 m) and there was greater reaction at the depths of 0.050.10 and 0.100.20 m when lime was incorporated. Surface or incorporated liming had no effect on grain yield, soybean oil and protein content. Gypsum improved chemical subsoil conditions, raising pH (0.01 mol L-1 CaCl2) as well as Ca2+ and S-SO4(2-) contents; it also caused exchangeable Mg2+ leaching in the soil profile. The application of gypsum did not affect grain yield, yet it improved soybean quality through an increase in protein and S contents, in 20032004, and in grain P, K and Ca, in the two cropping years. The use of gypsum in NT soybeans can be especially important for fields of seeds production.
