This study evaluates the feasibility of integration of the single-bud sugarcane and catfish farming system and the growth rate of both plants and fish. The observation started from September to November 2020. The design used was randomized with one factor. The treatments used were cultivation of single-bud sugarcane in polybags, hydroponic single-bud sugarcane cultivation, integration of single-bud sugarcane-catfish, and catfish cultivation. The results showed that the growth of sugarcane seedlings and the catfish indicate that the integrated cultivation system of sugarcane-catfish is feasible to apply. Such an integration system produces a better number of leaves, stem diameter, leaf area, and root length than the cultivation system of sugarcane seedlings in polybags. The weight of the canopy and the root of sugarcane seedlings in the integration system is also noticeable greater than the sugarcane seedlings cultivated in the polybag. In addition, the rate of catfish growth in the integration system is better than catfish's ordinary cultivation.   Keywords: hydroponic, integration farming system, single bud sugarcane planting

ABSTRACT The objective of this study was to evaluate the growth of crisp lettuce in hydroponic cultivation, following the nutrient film technique (NFT), using optimized mineral and organomineral nutrient solutions. The experiment was set in 8 x 3 factorial scheme, with treatments distributed in randomized blocks and split plots, with three replicates. The plots corresponded to eight nutrient solutions, of which four were mineral solutions with chemical composition suggested by Bernardes, Furlani, Castellane & Araújo and Ueda, and four were organomineral solutions, suggested by this research with chemical composition similar to those of the previously mentioned mineral solutions. The subplots corresponded to three varieties of crisp lettuce: Thaís, Vanda and Verônica. At 25 days after transplanting, the following parameters were evaluated: stem and crown diameter, root length, leaf area and number of leaves. For stem and crown diameters and number of leaves, the mineral solutions promoted the highest means. The mineral solution of Furlani and the organomineral solutions, except the modified solution of Castellane & Araújo, promoted the greatest root lengths. The smallest leaf area was obtained in the organomineral solution of Ueda. The cultivar Verônica had the highest root length and stem diameter.

Plantlet that has developed shoots and roots will have a high level adaptation in the field. The objective of this experiment was to improve the ability of planlet in shooting and rooting so that it is ready for acclimatization in the field. The increase ability in shooting and rooting of the planlet were conducted by adding various types of auxin in the media. The arabica coffee embryo of clone AS 2K which has entered the phase of the cotyledons was transfered into the treatment media containing half-strength of MS (Murashige & Skoog) macro and micro nutrient, vitamin B5, 30 g/L glucose, 100 ml/L coconut water, 50 mg/L AgNO3 added with the combination of IAA, IBA and NAA. The research was conducted by using completely randomized design with seven combined treatment i.e. 0.1 mg/L IBA, 0.1 mg/L NAA, 0.1 mg/L IAA; 0 , 1 mg/L IBA + 0.1 mg/L NAA, 0.1 mg/L IBA + 0.1 mg/L IAA, 0.1 mg/L NAA + 0.1 mg/L IAA; without auxin. There were 12 replications in every treatment and each replication consisted of five cotyledonary embryos. The parameters of observation were the root length, leaf number, leaf area, stem diameter, and height of plantlets. The observations were conducted in eighth weeks after cotyledonary embryo had shoots. The results showed that in the number of leaves and height of planlet parameters, the treatment without auxin was the best result compared to planlet with auxin addition. The addition of auxin varians and their combination did not significantly influent leaf area, root length and stem diameter parameters. The medium tested was optimum for the growth of shoots and roots of AS 2K arabica coffee.

Aims: To assess the field establishment of two tea cultivars under Cocoa Pod Husk (CPH) and Poultry Manure (PM). Study Design: Randomized complete block design arranged in Split-plots (cultivars as main plots and organic amendments as sub-plots) with four replications. Place and Duration of Study: Cocoa Research Institute of Nigeria stations in Ibadan and Owena, Southwest Nigeria between May 2016 and November 2017 (Rainy and dry seasons of 2016; Rainy season of 2017).  Methodology: Milled CPH and cured PM were applied each at the rates of 150 and 300 kg Nha-1 to established C143 and C318 tea cultivars on the field; unfertilized tea cultivars served as control. Data on number of leaves, number of branches, leaf area, plant height and stem diameter were collected on monthly basis; while dry matter was assessed at 15 months after transplanting. The data were analyzed with ANOVA and correlation at α.05. Results: The C143 performed better than C318 and 150 kg Nha-1 of CPH and PM enhanced the vegetative growth and dry matter of tea better than 300 kg Nha-1 in Ibadan and Owena. Cultivar 143 was significantly (P=0.05) better than cultivar 318 in number of leaves, number of branches and stem diameter in Ibadan; and in number of leaves and leaf area in Owena. CPH at 150 kg Nha-1 increased number of leaves, number of branches, leaf area, plant height and total dry matter by 135.11, 88.19, 346.12, 65.33 and 428.11% at Ibadan; and by 349.09, 245.41, 376.89, 80.89 and 231.49% at Owena, compared to control. On the interaction, tea cultivar 143 that received 150 kg Nha-1 CPH produced significantly (P=0.05) higher number of leaves, leaf area and total dry matter at Ibadan and Owena. Leaf area was positively correlated with number of leaves (r=0.87) in Ibadan and stem diameter (r=0.80) in Owena. Conclusion: CPH at 150 kg Nha-1 enhanced the growth and dry matter content of C143 tea established on the field in Ibadan and Owena, and is therefore recommended for tea cultivation in Southwest of Nigeria.

ABSTRACT The intensive cultivation of vegetables with frequent chemical fertilization may cause accumulation of nutrients in the soil. This, in turn, may reduce crop yields and damage the environment due to contamination of ground water and rivers. Thus, to increase the effects of P (0, 100, 200, 300 and 400 kg ha -1 of P2O5) and K (0, 60, 120, 180 and 240 kg ha-1 of K2O) doses on the growth and productivity of radish cultivars (Sakata 19 and Sakata 25) in a soil with high levels of these nutrients, two experiments were conducted in randomized blocks with the factors cultivars and doses arranged in a 2 x 5 factorial design with three replications. Number of leaves per plant, leaf area, shoot and root dry mass, total and commercial productivity, percentage of cracked roots and P and K contents in the plant and in the soil were evaluated. The Sakata 19 cultivar performed better than the Sakata 25 in both experiments. The fertilization with P or K did not influence the growth and the productivity of both radish cultivars. Therefore, both cultivars of radish evaluated do not need to be fertilized with P and K when planted in a Latosol with high levels of these nutrients.

Vegetables form major part of human dietary/nutritional needs. It provides the necessary vitamins and minerals as well as antioxidants to boost immunity. Different vegetables however have different benefits and require different growing conditions. This study investigated the effect of two growing conditions (Screen-house and open field) and soil amendments; Mexican sunflower compost (MSC; applied at 0, 5, 10 t/ha) and NPK 15:15:15 (applied at 0, 50 and 100 kg N/ha) on the growth performance, yield, and nutritional quality of five selected vegetables (Amaranthus cruentus, Celosia. argentea, Solanum macrocarpon, Solanum nigrum and Solanum incanum). Each treatment was replicated three times and experiment arranged in completely randomized design, Compost was applied a week before seed sowing vegetables grown in the screen-house generally performed better than the open field in terms of leaf area and chlorophyll content. The response however varied based on the vegetable and the soil amendments. Solanum species, performed better than Amaranthus under screen-house than open field. Chlorophyll in the leaf responded positively to NPK fertilizer under screen-house conditions while growth parameters such as plant height, stem girth, number of leaves under screen-house and field conditions varied depending on the vegetables. The number of leaves and leaf area increased with soil amendments. Moisture, crude protein and ash contents were reduced under open field compared to screen-house. The zinc and iron contents of the vegetable leaves showed that addition of compost was superior to NPK and screen-house better than open field. It can be concluded that vegetables grown in the screen-house performed better in their respective growth parameters than vegetables are grown under the open field.

The continuous destruction of our rainforest has threatened the existence of many useful and multipurpose plant species such as Tetrapleura tetraptera. To revert this situation, efforts must be made towards its sustainable use by encouraging reforestation which entails raising of seedlings for mass propagation of this crop. This study was aimed at comparing the effects of organic (chicken litter) and inorganic (NPK 15:15:15) fertilizers on seedling growth in four accessions of Tetrapleura tetraptera and hence determining fertilizer preference for this forest species. The Complete Randomized Design (CRD) was used in a factorial arrangement with four accessions and three fertilizer types in eight replicates. One month after transplanting, the fertilizers (organic and inorganic) were uniformly applied at the rate of 45 kg/hectare according to the experimental design. Data were collected monthly for a period of three months on plant height, stem diameter, leaf area, leaf length, member of branches, number of leaves, primary and secondary internode length per plant. Data on seedling emergence were also taken. Data collected were subjected to a two-way analysis of variance. Least significant difference (LSD) was used to separate significant means at p = 0.05. Result obtained revealed that the soil was rich in calcium, phosphorus and organic matter but low in nitrogen and potassium which were adequately complemented in mean days to seedling emergence in four accessions studied. Our findings also revealed that the organic (chicken litter) fertilizer did better (P<0.05) in all accessions than inorganic (NPK 15:15:15) fertilizer for all morphological traits studied. The performance of Cross River accession was outstanding as illustrated by the significant interaction obtained in most parameters. With chicken, litter fertilizer, Cross River accession produced the tallest plant (27.38 cm), largest leaf area (1.99 cm2), highest number of branches (20.13), highest number of leaves (66.75), longest stem diameter (0.93 cm), longest leaf length (1.94 cm), lowest primary (0.80) and lowest secondary (0.83) internode length. The use of organic fertilizers is therefore recommended for improved seedling growth of Tetrapleura tetraptera.

During summer in southern Georgia, greenhouses often reach or exceed 49C. Subsequently, transplants grown in these houses tend to exceed optimum height. To determine effects of N and P fertility levels on pepper (Capsicum annuum) transplant growth, applications of nutrient solutions with 58, 12, and 0 ppm N and 114, 57, and 0 ppm P205 were applied to recently emerged Capistrano bell pepper beginning 12 Aug. 1994. Plants were grown in polystyrene flats using a commercial noncharged artificial soil mix. Nutrient solutions were applied as needed to maintain adequate moisture until 31 Aug., except for two treatments that received only water after 22 Aug. Data were taken on 22 and 31 Aug. With 58 ppm N, 0 P decreased plant height, leaf count, leaf area, and plant weight. Higher N increased plant height, ratings of intact root plugs and washed roots, stem diameter, leaf count, leaf area, and plant weight. At 12 ppm N, P had no significant effect on transplant growth. Withholding fertilizer the final week reduced plant height, ratings of intact root plugs, stem diameter, number of leaves, leaf area, and plant weight.

Khaya senegalensis (Desr) A. Juss is a perennial deciduous tree which has many uses in developing nations. The population of the tree is rapidly declining due to no conservation efforts to prevent the species from endanger and extinction. At the moment there is dearth information on manure types required to raise healthy seedlings of the tree species in the study area. To conserve this genetic resource, germination and early growth rate experiment was carried out using seeds collected from three locations (eco-zones) (Alkaleri, Bauchi and Toro). Matured seeds of K. senegalensis were collected from mother tree stand in the three locations. One hundred and fifty seeds (150) from each location were sown in perforated polythene pots at an average depth of 2-3 cm. After germination i.e. 30 days after planting, different manures were applied to the seedlings. The experiment was laid out in a Completely Randomized Design (CRD) with three treatments, namely: poultry dung, cow dung and NPK manures; the experiment was replicated four times. Data on seeds germination variables of interest (seedling heights, number of leaves, collar diameter, leaf area, leaf width, leaf length and fresh weights) were measured. Seedlings height were measured using meter rule, collar diameters using a venier caliper, numbers of leaves were determined by manual counting the number of leaves on the seedlings, leaf area was measured by tracing leaves of seedling on a graduated graph sheet. Data collected on seed germination and early growth rate were subjected to descriptive statistics and inferential statistics (ANOVA). Where significant differences occurred, Tukey test was used to separate the means. Based on this finding, germination of seeds commenced after 10 to 14 days. Locations and manure types had significant effects on the mean heights, number of leaves, collar diameter, leaf area, leaf width, length and fresh weights of K. senegalensis seedlings in the study area. Thus, for species conservation and genetic heredity, seeds sourced from Bauchi eco-zone was the best with poultry manure as the best performed manure for the raising of K. senegalensis seedlings in the study area.
