ABSTRACT The objective of this study was to evaluate the growth variables of eggplants seedlings produced in substrates with different compositions in agricultural residues. The experiment was carried out in a completely randomized design, with five treatments and ten replicates, with the following treatments: T0= Bioplant commercial substrate (control); T1= 10% of moinha (dried residue of coffee beans) + 15% of coconut fiber + 5% of eggshell + 70% of commercial substrate; T2= 20% of moinha + 15% of coconut fiber + 5% of eggshell + 60% of commercial substrate; T3= 30% of moinha + 15% of coconut fiber + 5% of eggshell + 50% of commercial substrate; T4= 40% of moinha+ 15% of coconut fiber + 5% of eggshell + 40% of commercial substrate. The evaluated variables were electric conductivity of the substrate, number of leaves, plant height, stem diameter; and fresh and dry biomass of shoot, root, and of the whole plant. Growing doses of moinha provide increased electrical conductivity in substrate. The treatment groups containing increasing proportions of moinha in the substrate composition present the highest values of growth variables in relation to the commercial substrate. Except shoot, root and total dry biomass, the substrate with 10 and 20% of moinha have the highest values of analyzed variables in eggplant seedlings.

The choice of a substrate that meets the nutritional and physical demands of papaya seedlings with the use of organic wastes is directly linked to increases in crop yield and is an important environmental and economic alternative. Aiming to produce good-quality papaya seedlings while considering the composition and availability of substrates, this study examined the influence of applying increasing rates of poultry litter biochar as a substrate component in the production of papaya seedlings. The study was developed in a protected environment belonging to the Federal University of Campina Grande (UFCG). The experiment was laid out in a completely randomized design with a 6 × 2 factorial arrangement consisting of six rates of biochar (4, 8, 12, 16 and 20 t ha-1 and the control) and two papaya cultivars (Formosa and Ouro), with four replicates. Plant height, stem diameter, number of leaves and leaf area were evaluated 90 days after sowing. The fresh and dry biomass of shoots and root system and the Dickson Quality Index were also evaluated. In conclusion, the rates that provided good development of papaya seedlings were 8 and 16 t ha-1, and papaya cultivar Ouro showed better growth results.

Peanut is an oilseed cultivated in semiarid region. However, the lack of knowledge about irrigation and fertilization makes it difficult to increase its yield. Thus, the aim of this research was to study the effect of irrigation with water of different electrical conductivities and application of biofertilizer in peanut Br1. The research was carried out from August to November, 2014 at the State University of Paraíba - Campus IV, Brazil. The study was performed in a completely randomized design in a 4x2 factorial scheme, with four replicates. The treatments were related to different electrical conductivities in the irrigation water: (S1 = 0.8; S2 = 1.5; S3 = 3; e S4 = 4.5 dS m-1) with and without biofertilizer application. It was verified that the electrical conductivity influenced significantly all analyzed variables, except root fresh mass. For biofertilizer application, according to the Tukey´s test, only plant height and number of leaves were significantly influenced. Electrical conductivities in irrigation water above 0.8 dS m-1 reduce peanut growth and biomass production. The application of biofertilizer provides positive results in peanut cultivation in a Fluvic Neosol.

Plants in the genus Ficus are one of the most used in the ornamentals. it is also used for plant handcrafting such as braid, cylinders, and wall rockets, using a single plant or braiding some plants. The ficus are commonly asexually propagated by slip or shoots. There is the possibility to graft and to obtain plants with two levels of foliage, combining the color and texture. The objective of this research was to evaluate the grafting compatibility of varieties of Ficus benjamina, such as: Vivian, Winter green, and Antillean (green color) grafted on the variety Profit (white color) used as rootstock. The study was carried out under environmental conditions of the Mexican Dry Tropic in Tecomán, Colima, Mexico. The grafting method was by whip or tongue approximation. Bud sticks of the four varieties ≈70-cm long were used as scions. They were previously rooted in polyethylene bags containing 1.5 kg of coconut fiber used as rooting substrate. The rootstocks were grown long in soil until 1.5 m and when they reach similar diameter to the scions. The grafting height and diameter was ≈50-60 cm, and 2-2.6 cm, respectively. Five grafted plants were used as experimental unit, and the treatments were distributed in a completely randomized design with four replications. The variables estimated were: number of leaves after 28 and 35 days post-grafting, and percentage of grafting at 28 and 35 days post-grafting. The tree varieties were compatible with the rootstock, and no differences were obtained between the treatments (Tukey test P< 0.05); both three varieties exhibited 75% of grafting success, and `Antillean' had higher number of leaves, but the three varieties were statistically similar.

The Fertigation is the combined application of water and nutrients to a crop. It can be adapted to all types of agricultural crops. The objective of this study was to evaluate the effect of urea concentration in irrigation water on electrical conductivity of the soil solution and saturation extract along the first cycle of banana cv. Terra Maranhão. The experiment followed a completely randomized design with six treatments and ten replications. Treatments regarded for using three urea concentrations (1.0; 2.5 and 4.0 g L-1) in irrigation water applied by two micro irrigation systems (microsprinkler and drip). Results showed that there was a linear elevation of electrical conductivity of saturation extract and soil solution with the increase on concentration of urea in the injection solution. Urea should be used under concentrations up to 2.5 g L-1 in irrigation water without causing increase on electric conductivity of soil solution and saturation extract, considering 1.1 dS m-1 as the tolerated value for the crop. Nitrate in the soil solution increased significantly with the increase of urea concentration in the injection solution. The maximum concentration of nitrate in the soil occurred for 4,0 g L-1 concentration of the injection solution.

The experiment was conducted to study the comparison on biomass production of fodder germplasm. Para (Brachiaria mutica Stapf.), German (Echinochloa crusgalli L.) and Dhal (Hymenachne pseudointerrupta C. Muell) grasses were cultivated in a completely randomized design (CRD). The whole area was divided into nine plots. The area of each unit plot was 6 m x 6 m. Number of cuttings were 16,000 /hectare where Plant to Plant distance was 16 cm and row and raw distance was 16 cm. Equal amount of organic and chemical fertilizer were applied in all cutting. The fodders were first harvested after 60 days of planting, second and third after successive 60 days of re-growth. The findings of the study showed that fresh biomass (p<0.01) and dry biomass yield (p<0.05) of three fodder germplasm differed significantly. Crude protein and organic matter yield were significant (p<0.01) only in the second cutting. German grass was showed significantly higher in CP and OM yield (p<0.01) at second cutting than other grasses. However, no significant effect on plant height was observed among three grasses. From the above findings it may be concluded that among the three fodder germplasm, German fodder showed best result in respect of biomass production.

Abstract: Angico is a species found in several environments in Brazil, with several applications. It is used in the timber industry and mainly in folk medicine. In order to verify a variation in the biometric characteristics and the quality of seeds from different mother-plants in different harvesting years, the following variables were studied: moisture content, diameter, density, electrical conductivity, fresh and dry matter of seedlings, germination percentage and kinetics, in a completely randomized design with a 2x3 factorial arrangement (lots x size). The obtained results showed that angico seeds from different lots showed different physiological quality, possibly due to the climate variations to which mother-plants were submitted in the different years. Seed size directly interferes with seedling growth under both controlled and greenhouse conditions, and it can be used as a vigor indicator for angico seeds.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.
