The objective of this work was to verify the influence of light environments combined with rhizobia inoculation on cowpea growth and productivity. A completely random design was used in a 4x4 factorial scheme, with four light environments, four nitrogen sources and eight replicates in split plot parcels. Light environments were set by means of photo-conversion and thermo-conversion nettings (Aluminet®, red net and black net) and control treatment without shading (full sun). Nitrogen sources were constituted by the strains INPA 03-11B - SEMIA 6462 (Bradyrhizobium elkanni) and UFLA 03-84 - SEMIA 6461 (Bradyrhizobium viridifuturi), and two control treatments: with 70 kg ha-1 of mineral nitrogen and without N. Plant height, indices of chlorophyll a, b and total chlorophill, the number of leaves, number of nodules, dry matter of nodules, dry matter of the aerial portion, dry matter of roots and total dry matter, relative efficiency, gathering of nitrogen in the aerial portion, number, length and matter of pods per plant and dry matter of 100 grains, were evaluated. . There was interaction between light conditions and nitrogen sources for the number of nodules. Individual effect was observed in all other variables. Strain INPA 03-11B was able to promote higher nodulation in cowpea plants in light environments under full sun and Aluminet and the strain UFLA 03-84 only under full sun conditions. However, the efficiency of diazotrophic bacteria to promote vegetative growth, nitrogen gathering and production was not influenced by different light environments. Thus, full sun cultivation is recommended, independently of the nitrogen source used.

An experiment was conducted at the Horticulture Farm of the Bangladesh Agricultural University, Mymensingh to evaluate the effects of sulphur and GA3 on the growth and yield performance of onion cv. BARI Peaj-1. The experiment included four levels of sulphur viz., 0 (control), 15, 30 and 45 kg/ha and four concentrations of GA3 viz., 0 (control), 50, 75, 100 ppm. The experimental findings revealed that sulphur and GA3 had significant influence on plant height, number of leaves per plant, bulb diameter and length, individual bulb weight, splitted and rotten bulb, bulb dry matter content and bulb yield. The highest bulb yield (13.85 t/ha) was recorded from 30 kg S/ha, while the lowest bulb yield (11.20 t/ha) was obtained from control. Most of the parameters showed increasing trend with the higher concentration of GA3. Application of GA3 @ 100 ppm gave the maximum bulb yield (15.23 t/ha), while the minimum value (10.10 t/ha) was observed from control. Almost all the parameters were significantly influenced by combined treatments of sulphur and GA3 except bulb length of onion. The maximum bulb dry matter content (13.50%) and bulb yield (17.10 t/ha) were produced from the application of sulphur @ 30 kg/ha with 100ppm GA3, while the minimum bulb dry matter content (9.23%) and bulb yield (9.33 t/ha) were recorded from control treatment of sulphur with GA3.DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16749 Progress.

This study was carried out in the nursery of Department of Horticulture and Landscape Design, College of Agriculture, University of Basrah during 2018 growing season. Completely randomized blocks design (C.R.B.D.)  was used to investigate the effect of different concentrations of super swing (0, 0.5 and 1) g.l-1 and whey (0, 50 and 75) % and their interactions to enhance the growth parameters and chemical characteristics of Sour orange transplants. The results showed a significant increase in most of the measured growth parameters of transplants treated with high concentration of foliar spraying to both fertilizers. Application of super swing at 1 g.l-1 with whey at 75% together significantly increased the height of plant, the number of leaves, leaf area, the diameter of stem, number of flowers, the leaves content of both nitrogen and potassium, percentage of dry matter, and content of chlorophyll. Whereas, control treatment was significantly increased the water content compared to other treatments. Addition of growth-enhancing compounds such as super swing and whey extract to the plant can improve the metabolic performance and enhances the plant's ability to absorb nutrients from the soil.

The objective is to analyze techniques to form mulberry seedlings with different cutting sizes and forms of fertilization with N-P-K aiming a low production cost and an easy application in field. The experiment was carried out in a screened nursery, with a shading of 34%. The treatments were distributed in randomized blocks (RB) and compared in a 2x4x3 factorial design with five replications and 12 plants per plot. The factorial design consisted of two cutting lengths (10 and 20 cm) distributed in plastic tubes of 70 and 120 mL, four mulberry cultivars (IZ40, IZ10/1, Korin, and IZ3/2), and two types of fertilization: addition of 84 g of Osmocote® for each kilo of substrate, fertigation with aqueous solution containing 84 g of 14-14-14 N-P-K for each kilo of substrate, plus a control treatment (without fertilization). The commercial substrate Basaplant citrus® was used. 90 and 140 days after planting, assessments of percentage of rooting were carried out. At 140 days, shoot length (cm), number of shoots, number of leaves, root length (cm), and shoot and root green and dry matter were evaluated. The data obtained were evaluated using the Sanest software and Tukey test (P<0.05). Cuttings of 20 cm in length in tubes of 120 mL are recommended for the best formation of mulberry seedlings with the application of N-P-K fertilizer through fertigation. The cultivars showed different rooting potentials and shoot development. The best results are for Korin and IZ 10/1.

The effects of application of Azospirillum brasilense and thiamine on chlorophyll concentration and forage mass of Urochloa decumbens were evaluated in a small plot experiment conducted in Goiânia, Goiás, Brazil. The treatments were applications of: A. brasilense (concentration of 10 mL/L); thiamine at 2 concentrations: 50 and 100 mg/L; combinations of A. brasilense and thiamine at the 2 concentrations; and a Control treatment (untreated grass). At the first harvest there was a trend for applying A. brasilense, either alone or in combination with thiamine, to increase the concentrations of chlorophyll, but differences were not always significant at P<0.05. Dry mass of forage from applying A. brasilense plus thiamine at 100 mg/L was greater than that for Control and thiamine at both concentrations. At the second harvest, chlorophyll concentrations were not affected by treatment (P>0.05), while dry matter production of forage from applying A. brasilense alone and thiamine at 100 mg/L was greater (P<0.05) than that of Control and thiamine at 50 mg/L. Larger-scale and longer-term studies to validate these preliminary findings are needed.

Forty-five male Sapphire mink kits were allotted to three treatment groups and fed for approximately 100 days (August 1–November 7). The control diet (treatment 1) consisted of horse-meat 10%, cooked chicken by-products 15%, raw cereal 25%, and whole frozen fish 50%. The frozen fish was replaced by either herring meal or soybean meal on an equivalent dry matter basis for treatments 2 and 3. Average mink weights on November 7 were 1.78, 1.87, and 1.92 kg for the soybean meal, herring meal, and control treatment groups, respectively, and were not significantly different (P > 0.05). The feeding period was divided into a growing phase (period 1), a growing and furring phase (period 2), and a maintenance and a priming phase (period 3). The average daily weight gains during these periods were: period 1: 15.2, 18.0 and 11.8 g; period 2: 6.1, 6.7 and 7.8 g; period 3: +0.8, −2.6 and −0.7 g, for the control, herring- and soybean meal-fed mink, respectively. Digestibility trials were carried out during each period. Dry matter and energy digestibilities were significantly higher (P < 0.05) for the herring-fed and control kits than for the soybean meal-fed kits. There was no significant difference (P > 0.05) in nitrogen balance among treatments. Skin biopsies were taken at pelting time to compare fur density, with values of 19.6, 20.6, and 19.5 hairs per pore, for the soybean-, herring-fed and control kits, respectively.

Guarana (Paullinia cupana var. Sorbilis (Mart.) Ducke) is a species native from Amazon which has high caffeine concentration. The interactions between guarana and microorganisms in Amazonian soils need to be investigated, especially in relation to the seedling production process, due to its beneficial relationships such as biosynthesis and the supply of stimulating substances, which may result in shortening of the nursery garden or increased productivity. Thus, this research had the objective of evaluating the potential of growth caused by rhizobacteria (Burkholderia ambifaria and Bacillus sp.) in rooting of guarana seedlings. The root length, volume, dry matter of the aerial part, height, number of leaves, leaf area and dry matter of shoot were evaluated at 180 days after planting emergence. Were also determined the carbohydrate and proline content of the aerial part. The rhizobacteria did not influence the growth of the seedlings, however, the carbohydrate contents were higher when the inoculation of the rhizobacteria was carried out with the Burkholderia ambifaria bacteria in the cultivar BRS-Amazonas, with the best results. The proline levels were higher in the control treatment of the two cultivars.

ABSTRACT Inoculating crops with diazotrophic bacteria constitutes a feasible biotechnological tool to reduce or even avoid the use of nitrogen fertilizers and to improve the nutritional status of crops. However, the potential use of such technology is limited due to the lack of studies in diverse vegetable crops. We evaluated the production of chicory (Cichorium intybus) in response to inoculation with diazotrophic bacteria in two soil classes. The experiments were performed under greenhouse conditions and under a completely randomized design. The treatments were constituted by strains UFRB FA34C2-2, UFLA 03-84 and INPA 0311B, and two control treatments (devoid of bacterial inoculation and with and without nitrogen fertilization). Two experiments were carried out, one using a soil classified as a dystrophic yellow Latosol (Oxisoil) and one using a Quartsandy Neosol (Typic Quartzipsamment). Chlorophylls a, b and total; plant height; number of leaves; dry mass of the aerial portion; dry mass of roots; total dry mass; effectiveness; efficiency in addition to N and P gathering in the aerial portion, were evaluated 60 days after seeding. The inoculation with diazotrophic bacteria resulted in adequate production when compared to the control treatment without nitrogen fertilization and without inoculation. Diazotrophic bacteria showed potential supplying nitrogen to chicory plants and spare the use of nitrogen fertilization in both soil classes. The strain INPA 0311B, recommended for cowpea, promoted vegetal growth and increased the dry weight of the aerial portion in chicory, under both dystrophic yellow Latosol (Oxisoil) and Neossolo Quartzarênico (Typic Quartzipsamment), when cultivated under greenhouse conditions.

ABSTRACT Fifteen Friesian oxen between 12 and 18 months of age with a mean body mass of 240.7 kg were randomly assigned to diets containing 0.25 % phosphorus (P) or less, to evaluate the acute effects of an acidiogenic diet of -11.1 meq/100 g of diet dry matter, compared with a basiogenic diet of +25.6 meq/100 g or a control diet of +16.5 meq/100 g of diet dry matter calculated as (Na + K) - (Cl + S), on blood, bone and faecal P, calcium (Ca) and magnesium (Mg) for a period of 9 weeks. Blood, bone and faecal responses to an anionic diet are described. An inverse relationship existed between bone and blood Ca, in which there was resorption from bone with increased blood Ca in response to the anionic diet. The anionic treatment group demonstrated simultaneous increases in bone, blood and faecal P concentrations at various stages of the experiment compared to the cationic and control treatment groups. Results indicate independent absorption and resorption of Ca and P into and out of bone. There was wide variation in the bone Ca:P ratio between 2.02 and 1.51 among animals fed the anionic diet, with the Ca:P ratio following Ca values and not bone P values. Bone and blood P had a linear relationship with dietary cation:anion balance (DCAB), increasing as the diet became more anionic in nature, but faecal P was curvilinear with highest concentrations at -11.1 and +25.6 meq/100 g compared to +16.5 meq/100 g. Concurrent blood, bone and faecal P increases at some stages of the experiment indicate a P-sparing effect of the anionic diet and warrants further research into the long-term effects of anions in the diet, leading to their use as a possible addition to improved licks in P-deficient areas.

The Effect of Different Kind of Polyethylene Film Used as a Low Tunnel Cover on Celery Yield and Stalk QualityEarlier experiments showed that celery could be grown under different plastic covers for spring and autumn harvest. The most significant for yield quantity and quality were light conditions. In conducted studies (2005-2007) the effect of three different covers for low tunnels: transparent, white and black film (made of original and recycled polyethylene) on the growth, yield and some quality factors of celery Tango stalks was estimated. Only small differences in the length of celery stalks grown under different films were observed. In the third year of experiment stalks grown under black film were around 1cm longer than all the others. Mean values of the yield indicate that transparent film used as a cover and the control treatment increased slightly the obtained yield but the differences did not exceed several percent. Plants grown in more favourable light conditions accumulated more dry matter as well as more soluble sugars in celery stalks. No such differences were observed under original and recycled films.

One of the main stages in the production system of a crop is the production of quality seedlings since it influences the plants' final performance in the field and their production. The study aimed to evaluate different nutrient solutions in the production of Cambuci pepper seedlings. The design used was a complete randomized design, with six treatments corresponding to the nutrient solutions proposed for the pepper crop by Castellane and Araújo, Claudio Roberto, Hoagland, and Arnon, besides the commercial products Plenan® and Biobokashi®, and a control treatment without fertilization, with six replications. The final evaluation was carried out 45 days after sowing. The following variables were analyzed: stem diameter, plant height, leaf dry matter, shoot dry matter, the number of leaves, relative chlorophyll index ("Spad"), and Dickson quality index. The seedlings subjected to the applications of Claudio Roberto and Hoagland and Arnon solutions have the highest heights and number of leaves, the largest stem diameter, shoot dry matter, leaf area, and Dickson quality index with 2.60 and 2.51 mm, 0.54 and 0.62 g, 38.64 and 41.91 cm2, and 0.107; 0.097, respectively. The Hoagland and Arnon nutrient solution provided the best characteristics to produce Cambuci pepper seedlings.
