TL;DR: Results revealed that poultry manure is a suitable source of nutrients for tomato especially if applied at 30 t ha-1 in the forestsavannatransition zone of southwest Nigeria and is therefore recommended for sustainable productivity.
Abstract: Four field trials were conducted during the years 2006 and 2007 at Owo, the forestsavannatransition zone in southwest Nigeria, to study the effect of poultry manure (PM), NPK 15-15-15 fertilizer and NPK 15-15-15 fertilizer + poultry manure on the growth and yield of tomato.Seven treatments were applied to the soil: 0, 10, 20, 30, 40 t ha-1poultry manure , 300 kg ha-1 NPK 15-15-15 fertilizer and 150 kg ha-1 NPK 15-15-15 fertilizer + 10 t ha-1poultry manure. These werelaid out in a randomized complete block design and replicated three times. The treatments werecompared on the basis of their effect on soil chemical properties, leaf nutrient content, growth andyield of tomato. All levels of poultry manure and NPK 15-15-15 fertilizer + poultry manureincreased leaf N, P, K, Ca and Mg levels. The soil chemical properties except pH increased withamount of poultry manure. NPK 15-15-15 fertilizer alone did not increase the soil and leaf Ca andMg. All levels of poultry manure, NPK 15-15-15 fertilizer alone and NPK 15-15-15 fertilizer +poultry manure increased the number of leaves, plant height, leaf area, number of fruits and fruitweight significantly. Among poultry manure levels, 30 t ha-1poultry manure gave the highest fruityield. Among the seven treatments, NPK 15-15-15 fertilizer + poultry manure gave the highestyield. On an average over the two years, 10, 20, 30, 40 t ha-1poultry manure, 300 kg ha-1 NPK 15-15-15 fertilizer alone and 150 kg ha-1 NPK 15-15-15 fertilizer + 10 t ha-1poultry manuretreatments increased fruit weight by 19, 36, 51, 14, 20 and 83%, respectively. Results revealed thatpoultry manure is a suitable source of nutrients for tomato especially if applied at 30 t ha-1in theforest-savanna transition zone of southwest Nigeria. The combined use of NPK 15-15-15 fertilizerand poultry manure increased tomato yield compared to the application of NPK 15-15-15 fertilizeror poultry manure alone and is therefore recommended for sustainable productivity. In addition,lesser quantities of poultry manure and NPK 15-15-15 fertilizer would be required, therefore,reducing the amount of money spent on chemical fertilizer

Abstract: Tillage and fertilizer influenced soil characteristics through their effects on soil properties which in turn affect crop performance. Field experiments were conducted during 2006 and 2007 cropping seasons on an Alfisol (Oxic Tropuldalf) at Owo in the forest-savanna transition zone of Nigeria to evaluate the effect of tillage and fertilizer types on soil properties and sweet potato yield ( Ipomoea batatas L.). Two tillage treatments namely: zero tillage (ZT) and conventional tillage (CT) were combined with each of NPK-15-15-15 fertilizer at 250 kg ha −1 , poultry manure (PM) at 10 t ha −1 , combined application of 125 kg ha −1 NPK 15-15-15 fertilizer + 5 t ha −1 poultry manure and a control (no fertilizer/manure). The experiment was laid out on a randomized complete block design in a factorial combination of eight treatments that were replicated three times. The surface soil (0–15 cm depth) was chemically analysed before and after crop harvest and some selected soil physical properties, leaf nutrient concentrations, growth and sweet potato yield were determined. Conventional tillage plots had significantly lower soil bulk density (1.30 Mg m −3 ) than zero tillage plots and resulted in higher leaf N, P, K, Ca and Mg and tuber yield of sweet potato compared with zero tillage. Soil water content was higher, whereas temperature was lower, in zero tillage than conventional tillage. Zero tillage had significantly higher concentrations of soil pH, organic C, N, P, K, Ca and Mg for surface soil (0–15 cm depth). Conventional tillage increased mean tuber yield of sweet potato by 30% compared with planting on untilled zero soil. Application of poultry manure alone and complementary application of NPK fertilizer and poultry manure reduced bulk density and temperature and increased soil water content and porosity, whereas NPK fertilizer did not improve soil physical properties. Compared with control, poultry manure alone, NPK fertilizer alone and complementary application of NPK fertilizer and poultry manure increased soil total N, available P, and exchangeable K, Ca and Mg concentrations as well as leaf N, P, K, Ca and Mg concentrations. Poultry manure tended to improve soil pH, SOC, N, Ca and Mg compared with NPK fertilizer. Combined application of sub-optimal rates of NPK fertilizer and poultry manure gave higher soil and leaf N, P and K concentrations, vine length, vine girth, leaf area and tuber yield compared with NPK fertilizer or poultry manure alone. Compared with control, NPK fertilizer, poultry manure and NPK fertilizer plus poultry manure increased tuber yield by 39, 45 and 83%, respectively. Conventional tillage in combination with NPK fertilizer plus poultry manure gave the highest tuber yield of sweet potato.

TL;DR: A field experiment was conducted in the forest-savanna transition zone of Nigeria from May to July 2014 and September to November 2015 to determine the impacts of poultry manure (PM) and NPK fertilizer on soil physical properties, and growth and yield of carrot (Daucus carota L).
Abstract: A field experiment was conducted in the forest-savanna transition zone of Nigeria from May to July 2014 and September to November 2015 to determine the impacts of poultry manure (PM) and NPK fertilizer on soil physical properties, and growth and yield of carrot (Daucus carota L.). The five treatments included no manure or fertilizer (control); 10, 20, and 30 megagrams (Mg)·ha-1 of PM; and 300 kg·ha-1 of 15 N-15 P-15 K fertilizer. All levels of PM reduced soil bulk density and temperature, and improved total porosity and moisture content compared to the NPK fertilizer and the control. Plant height, number of leaves, root diameter, root length, and fresh root yield in the PM and NPK fertilizer treatments were improved compared to the control. Growth and yield parameters of carrot plants treated with 20 and 30 Mg·ha-1 PM were higher than the other treatments. The 10 Mg·ha-1 PM and NPK fertilizer treatments produced similar growth and yield responses. There was an interaction for year (Y) × fertilizer (F) on plant height, number of leaves, and fresh root yield. Relative to the control 10, 20, or 30 Mg·ha-1 PM and NPK fertilizer increased fresh root yield of carrot by 39.9%, 62.0%, 64.9%, and 37.3%, respectively. The 20 Mg·ha-1 PM treatment best improved soil properties and carrot productivity as indicated by the benefit-to-cost ratio.

TL;DR: In this paper, the suitability of varieties that various seed-sector policies try to disseminate has been addressed using rice in Nigeria as an example, showing that rice varietal development in Nigeria has been lagging behind that of other developing countries in Asia and Latin America, due partly to insufficient investment in domestic rice R&D.
Abstract: Seed is an important input in agriculture. Appropriate seed policy enables the supply of good varieties to farmers at a low cost. Thus, improved seed-sector functions, including seed subsidies, effective regulations, certifications, and efficient private-sector participation, receive significant attention. Relatively less attention, however, has been given to the suitability of varieties that various seed-sector policies try to disseminate. For countries like Nigeria, where agricultural research and development (R&D) has long been incapacitated, seed-sector policies may often have insufficient outcomes, not so much because of the efficiency of those policies but mostly because varieties being promoted are outdated (even though they are called improved varieties) or suitable only in certain environments but not in most of the other areas with diverse agroecological conditions. This paper addresses these issues using rice in Nigeria as an example. First, this paper shows that rice varietal development in Nigeria has been lagging behind that of other developing countries in Asia and Latin America, due partly to insufficient investment in domestic rice R&D. The paper then illustrates using a household model simulation that impacts of certain policies, such as the seed subsidy, may be greater (smaller) if they are applied to good (poor) varieties. The paper concludes by discussing key policy implications and future research needs.

TL;DR: Application of 20 to 40 t/ha composted cattle manure befor planting and addition of commercial organic fertilizers such as coplex, nof and ormin K can be used as an alternative to the chemical fertilizers in indeterminate tomato cultivation.
Abstract: The purpose of this study was to evaluate the effects of different organic fertilizers on yield and fruit qualities of indeterminate tomato. Influences of different organic and inorganic fertilizers on yields and fruit qualitiy of tomato were compared during 2006 and 2007 growing periods under field conditions. In 2006 growing period, organic fertilizes used were Ormin K (250 kg/ha before planting; 30 kg/ha after first flowering; 80 kg/ha after first harvest), Coplex (50 kg/ha every week from planting to last harvest), Nof (40 kg/ha every week, from planting to last harvest), composted poultry manure (CPM) (1 t/ha before planting; 0.5 ton/ha after first flowering and 0.5 ton/ha after first harvest (liquid form)) and composted cattle manure (CCM) (60 t/ha before planting; 5 ton/ha after first flowering and 5 ton/ha after first harvest (liquid form)). Based on the first year results, organic fertilizers used during 2007 growing periods were F1 (20 ton/ha CCM before planting; 1 t/ha CPM before planting; 40 kg/ha Coplex and 20 kg/ha Nof every week) and F2 (20 t/ha CCM before planting; 500 kg/ha Ormin K before planting; 30 kg/ha Coplex and 30 kg/ha Nof every week). Inorganic fertilizers used as a control were N: 450, P2O5: 350, K2O: 600, CaO:50, S: 200, and Mg:50 kg/ha. Tomato cultivars used in this study were Alida FA± in 2006 growing period and Alida FA±, YankA± FA± and Maya FA± in 2007 growing period. In 2006, the highest yields obtained from CPM, CCM, and control treatments were 128.12, 122.92 and 115.24 t/ha respectively. In 2007, marketable yield obtained from F1 fertilizer treatment was similar to the control application. Unmarketable yield was not effected from the different fertilizer treatments. There was no significant difference among the treatments. However fruit cracking rates were higher in organic fertilizer treatments than the inorganic fertilizer treatment. Finally, application of 20 to 40 t/ha composted cattle manure befor planting and addition of commercial organic fertilizers such as coplex, nof and ormin K can be used as an alternative to the chemical fertilizers in indeterminate tomato cultivation.
Key words: Tomato, organic fertilizer, cattle manure, poltry manure, yield.
