AbstractChemical fertilizers for boosting crop production are becoming more expensive and scarce. Green amaranth (Amaranthus caudatus L.) is a fast growing and highly nutritious crop, but its common use in the diet of Nigerians is constrained by its high demand for nitrogen fertilizer. Thus, there is a need to find local fertilizer materials that are readily available to peasant farmers. A preliminary field study was conducted to evaluate urine and neem (Azadirachta indica L. juss) as alternative sources for mineral fertilizers in fortifying organic fertilizer (OF) made from cow dung and market waste compost, and OF fortified with urea and bone meal [organo-mineral fertilizer (OMF)], for yield and growth of green amaranth. Fifteen treatments, based on the percentages of N supplied, were NPK15-15-15, OMF, OF, urine, neem and ten treatments of 50, 60, 70, 80 or 90% OF supplemented with a total of 50, 40, 30, 20 and 10% urine or neem, respectively, to provide a total application rate of 100 kg N ha−1, with no fertilizer treatment as a control. Planting was done in two successions (main with fertilizer treatments and residual without further application). The fertilizer sources and levels had significant effects on plant height, number of leaves, stem girth, fresh weight and dry weight. The residual effects were also significant for plant height, number of leaves, total fresh and dry weights. Forty percent N urine amendment of the OF produced the highest total fresh amaranth biomass (269.3 g plot−1 main effect and 110.8 g plot−1 residual effect), which was significantly better than the values of (140 and 35.3 g plot−1, respectively) obtained with respect to OMF during main planting and NPK during residual planting. Results of our study reveal that 40% N urine fortification of OF was a viable substitute for synthetic fertilizers in production of amaranth, and that urine and neem cake can be alternatives to mineral fertilizer for crop production.

<p>The present study investigates the potential of olive mill wastewater, treated by microfiltration and XAD4 macroporous resin, to be used as liquid fertilizer in maize production through a 2-year field experiment. The treated olive mill wastewater (T-OMWW) was applied at two rates of 25 t and 50 t per ha per year, supplemented with mineral fertilization. There was also a treatment involving the application of only T-OMWW at the rate of 50 t per ha per year, and an only mineral fertilizer treatment. Mineral fertilizers and T-OMWW were applied progressively through a drip irrigation system.</p> Maize grain and soil analysis showed that T-OMWW was capable to meet crop requirements in N, P and K, and increase soil N, P and K availability. There was a tendency for increasing soil Na and electrical conductivity (EC) using the higher rate of T-OMWW. Therefore, for sustainable agriculture, it may be safer to apply the T-OMWW at the lower rate of 25 t per ha<sup> </sup>per year, or use the higher rate of 50 t per ha<sup> </sup>every other year.

Field experiment was carried out at the Teaching and Research Farm of Kwara State University, Malete, Ilorin, to evaluate the effect of compost, organomineral, and inorganic fertilizers on the growth and yield ofAmaranthus caudatusas well as its residual effects.Amaranthuswas grown with compost Grade B (unamended compost), organomineral fertilizer Grade A (compost amended with mineral fertilizer), and NPK 15-15-15 and no fertilizer (control). All the treatments except control were applied at the rate of 100 kg N/ha. The results indicated that theAmaranthusyield of 18.9 t/ha produced from Grade A was significantly (P<0.05) higher than 17.6 t/ha obtained from NPK fertilizer. Residual effect ofAmaranthusgrowth parameters such as plant height, number of leaves, and yield values obtained from Grade A was also significantly (P<0.05) higher than that of NPK, compost, and control values. Thus, organomineral fertilizer could be used in cultivation ofAmaranthus caudatusin Ilorin and in similar type of soil in similar agroecology.

This study aims at determing the response of growth and production of peleng vegetables to the application of liquid organic fertilizer in various mulch. The study was conducted on land located in Simalingkar A Medan with a height of ± 32 m above sea level, began from May to August 2017. The research method used a factorial randomized block design with 2 factors. The first factor is the dose of NASA liquid organic fertilizer (P) which consists of 3 levels of treatment, namely: P0 = control, P1 = 3 ml / l water and P2 = 6 ml / l water. The second factor is the provision of mulch (M) which consists of three types, namely: M0: without mulching, M1: rice straw mulch and M2: black silver plastic mulch (MPHP). The results showed that the treatment of NASA liquid organic fertilizer up to 6 ml / l water significantly increased plant height, number of leaves, fresh weight of plants per sample, fresh weight of plants per plot, dry weight of plants per sample and dry weight of plants per plot, but differed not markedly on the relative growth rate of plants. The treatment of organic mulch and black silver mulch significantly increased plant height, number of leaves, fresh weight of plants per sample, fresh weight of plants per plot, dry weight of plants per sample and dry weight of plants per plot, but not significantly different to the relative growth rate of plants. The interaction between NASA's liquid organic fertilizer treatment and mulch administration had no significant effect on plant height, number of leaves, plant fresh weight per sample, plant fresh weight per plot, plant dry weight per sample, plant dry weight per plot and relative plant growth rate

The present study aims to determine the residual effects of organic manure (biochar and cowdung) growth of P. osun under a screen house condition. Implementing the use of biochar and different organic sources has been proposed as an option for improving soil fertility, restoring degraded land and sequester large amounts of carbon (C) over the long-term. The study was carried out in Forestry Research Institute of Nigeria. Pterocarpus osun seeds were collected from the botanical garden at the University of Ibadan. The media for planting (soil) and treatments used had already been established from previous experiments done by using same species (Pterocarpus osun). Seedlings of P. osun were raised in a germination basket for four (4) weeks and twenty four (24) healthy seedlings were selected from the basket on the basis of uniform treatments and then transplanted into the already established media and the experiments were arranged in a completely randomized design (CRD). Data on growth parameters (plant height, number of leaves), collar diameter and dry matter yields were generated and subjected to analysis of variance. The significant means were separated by using LSD at 5% level of significance. The results showed that the interaction of Biochar + Cow dung (30 t/ha +135 g) had the highest diameter with a value of 5.17 mm when compared with the control (no amendments). The   highest plant height was recorded by the interaction of biochar and cow dung at 20 t/ha +135 g with mean value of 11.73 cm while sole application of cow dung also performed well in number of leaves with a mean value 11.50 as compared with the control (no amendment). It is concluded that there is a residual effect in the interaction of biochar and cow dung, which ultimately improves the performance of Pterocarpus osun.

Loss of soil fertility as a result of continuous cropping on the same piece of land has necessitated the need to improve soil fertility for better crop yields. Inorganic and organic fertilizers have been used to improve soil fertility, however, excessive use of soil amendments improve vegetative growth of plants thereby attracting large numbers of insect pests. Cow dung and poultry droppings were used as soil amendments in a field experiment using eggplant Solanum melongena. The effects of these organic manures were compared with inorganic fertilizer (NPK) and a control where there was no application of soil amendment in a randomized complete block design with 3 replicates. Parameters studied were pests’ and their numbers, plant height, number of leaves per plant, leaf area, stem girth and yield. The major insect pests identified on the plant were Bemisia tabaci, Aphis gossypii, Leucinodes orbonalis and Eublemma olivacea. Bemisia tabaci and Aphis gossypii scores were significantly larger on cow dung and poultry manure plots. Leucinodes orbonalis and Eublemma olivacea numbers were not significantly different on the treated and control plots. Mean plant height, number of leaves and yield differed significantly among the soil amended plots. Even though soil amendments improve the nutrient content of the soil and the yield of crops it could lead to increase in pests numbers and damage caused to plants.

Cuscus is an arboreal animal whose habitat is in the forest with the type of food consumed are fruits, leaf shoots, and agricultural plants. Animal manure can also be used as organic fertilizer for forage plants. This study aims to determine the growth response of Setaria grass (Setaria sphacelata) given a dose of cuscus manure fertilizer with banana and avocado consumption. The study was designed in a CRD with 3 treatments. The treatments were P0 = without fertilizer (100% soil), P1 = 40 g/polybag of cuscus manure with banana consumption, and P2 = 40 g/polybag of cuscus manure with avocado consumption. Planting is done by pols on polybags measuring 30 x 25 cm. The results showed that the highest plant height of Setaria grass was found in P2 with an average of 101.70, then P1 was 101.47 and P0 was 71.16 cm/week. The results were the same for the number of leaves and tillers, P2 showed significantly higher results (P<0.05), followed by P1 and control. The application of organic fertilizer of cuscus manure with the consumption of bananas and avocados can increase the growth of Setaria grass.

Organic fertilization in no-tillage system (NTS) has been used in regions milk production, in an order to provide nutrients for crops and provide a destination for high production of animal waste. The aim of this study was to evaluate the chemical attributes of an Oxisol, a function of organic fertilization with liquid manure from dairy cattle (LMDC) and mineral fertilizers. The experiment was conducted under NTS with crop rotation including legumes and grasses. The treatments were distributed in three randomized blocks with factorial arrangement, using three levels of mineral fertilizer (0, 50 and 100 % of the dose recommended for the crops) and four levels of organic fertilizer (0, 30, 60 and 90 m3 ha-1year-1). After six years of fertilizer management of crops, soil was collected from five depths (0-0.05, 0.05-0.10, 0.10-0.30, 0.30-0.50 e 0.50-0.80 m). The samples were determined the chemical pH, H++Al3+, Al3+, Ca2+, Mg2+, K+,electrical conductivity (EC), bases saturation (V), Ca2+/Mg2+ ratio, total organic C (TOC), B, Cl, Fe, Cu, Zn and Mn. The mineral fertilizers acidify the soil, raised the K+, P and EC and, changed the Zn and Cu contents. The organic fertilization with LMDC was a source of nutrients (Ca 2+, Mg2+, K+, P, Zn and Cu), raised the TOC and the EC, and kept the soil acidity attributes (pH, H++ Al3+ and V).

We studied the effect of the organic chicken manure on the growth and development of cocoa trees (Theobroma cacao L.), during their juvenile stage. The experiment was initiated in February, 1993, in three commercial plantations, 20 months old, located in the county of El Rama, Region V. During the following 14 months we carried out three application , comparing, the three levels of chicken manure (454 , 908 . and 1,362 g per tree and application) with mineral fertilizer (three applications , of 15-15-15fertilizers100 g per tree, plus one application of, urea 100 g per tree), and a check without any applications. A random complete bolck design was utilized and means were compared by, Duncan’s test and regression and correlation analyses were also made. The results showed that with the application of 1,362 g of chicken manure, a significatively higher effect over the initial production of cocoa, and an increase of the stalk diameter were observed. The applications of 454 and 908, of chicken manure resulted in production levels equal to those of the treatment with mineral fertilizers. In relation to plant height, we did not find statistical differences among treatments. The treatment without fertilizer , showed the smallest growth and lower production.
