This research was conducted on mature pomegranate (Punica granatum L. “Wonderful”) trees growing at a site located in North Coast, Matrouh Governorate, Egypt. The aim was to investigate the impacts of different irrigation regimes in combination with different fertilizer regimes on the fruit set, fruit retention, yield, and nutritional status of the trees. The experimental factors were arranged in a split-plot design, with four replicates per treatment combination. The results indicated that all of the characteristics measured, including leaves nutritional status, percentages of fruit set, fruit drop, fruit retention, fruit cracking, fruit sunburn, and marketable fruit, and yield were significantly affected by the interaction between the irrigation treatment which denoted by percentages of reference evapotranspiration (ETo) and fertilizer regime. The application of 75% mineral fertilizer + 25% organic manure under deficit irrigation of 80% ETo increased the yield by an average of 18.23% over the 2 years compared with 100% mineral fertilization under full irrigation, while 50% mineral fertilizer + 50% organic matter under 80% ETo gave the maximum percentage of marketable fruit (86.23% and 86.84% in 2018 and 2019, respectively). The maximum water use efficiency was obtained with the 80% ETo treatment combined with 75% mineral fertilizer + 25% organic manure in both seasons with values of 9.69 and 10.06 kg/m3 applied water, respectively. These results demonstrate that under the field conditions at the experimental site, the fruit set and retention could be improved by applying a reduced amount of mineral fertilizer in combination with organic manure and less irrigation water.

Ginger, Zingiber officinale is one of the most cultivated spices in the world. Therefore its production is often subject to high pest and disease pressures, particularly that of plant parasitic nematodes. For the sustainable management of parasitic nematodes of ginger, a trial was conducted at Agronomic Research Station of the Graduate School of Agronomy at the University of Lomé to assess the efficacy of some organo-mineral fertilizers on parasitic nematodes. An organic manure based on house waste valorization in three doses (0tha -1 ; 15tha-1 and 25tha-1 ) and five mineral fertilizer formulations from simple mineral fertilizers (Urea 46%, the chloride of potassium and the triple superphosphate): N0P0K0; N45P15K60; N70P50K50; N90P30K100 and N125P90K100) were used according to a split plot design. The inventory of the nematodes permitted to count five genders of nematodes: Meloidogyne; Xiphinema; Longidorus; Helicotylenchus and Pratylenchus. The results indicated that an input of 25 tons of organic manure associated with mineral fertilizer of N70P50K50 and N125P90K100 reduce nematode density by up to 58.62% in roots and 95.88% in soil compared to the treatment without manure and mineral fertilizer. The yield of fresh rhizomes vary from 2.9 to 7.7 t/ha with little statistically effects of the manures. This study reveals that nematodes constitute a serious phytosanitary problem for ginger and that the contribution of organo-mineral fertilization makes it possible to reduce the density of nematodes under ginger.

Roots effect is not generally considered in studies assessing the performance of crops in response to green manuring. However, such effect can contribute to a better understanding of crop rotation. The aim of this study was to assess the effect of root and shoot of two legumes on the production of cabbage. The experiment was conducted in pots of 10 liters containing substrate of 2:1 soil/sand. The experiment was arranged in a factorial scheme (2x3 + 2) in a randomized block design with five replicates using two legume species (Crotalaria juncea L. and Canavalia ensiformis L), three plant parts (root, shoot, or whole plant), and two additional treatments (mineral fertilization with 100% and 50% of the recommended dose of N for growing cabbage). Pots with legume treatments received mineral fertilizer with 50% of the recommended dose of N for growing cabbage. The experimental plot consisted of a pot containing one plant of cabbage. Legumes were grown in pots and harvested at 78 days. The root biomass was determined in extra pots. Production was assessed using head fresh and dry weight. The application of the whole plant of both legume species reduced cabbage production. However, root or shoot of both legume species was equivalent to 50% of mineral N fertilization required for the cultivation of cabbage.

The objective of this work was to evaluate the productive performance of broccoli under different top-dressing organic fertilizations. The experiment was conducted under protected cultivation, in a completely randomized design with four replications, with two plants per experimental unit. Broccoli seedlings were produced in a commercial substrate in styrofoam trays. The seedlings were transplanted to plastic pots containing 10.0 L of substrate made up of subsoil and organic compost at the ratio of 3:1 (v/v), respectively, which is equivalent to about 20.0 t ha-1 of organic compost at planting. After seedling establishment, the top-dressing fertilization treatments were applied: gliricidia biomass associated or not with liquid biofertilizer of cattle manure to the soil and bokashi. Two control treatments were established: one with mineral fertilization recommended for the crop and the other without top-dressing fertilization. The broccoli production was evaluated (commercial standard). Plants that received mineral fertilizer were more productive, however, they were not significantly different (p>0.05), by Dunnet test, from the plants fertilized with 2.5 t ha-1 gliricidiabiomass (dry mass) associated with liquid biofertilizer (2.0 L m-2) applied to soil. Top-dressing fertilizations with only gliricidia, at 2.5 and 5.0 t ha-1 of biomass (dry mass), resulted in no significant increase in production of broccoli inflorescence. The use of bokashi in addition to gliricidia biomass and liquid biofertilizer reduced the efficiency of the fertilization compared with plants that received only gliricidia and liquid biofertilizer.

Efficient use of co-composted organic manure with biochar is one of the sustainable management practices in an agriculture system to increase soil fertility and crop yield. The objectives of this research are to evaluate the use of co-composted biochar, biochar in formulation with poultry litter (PL), and PL compost on soil properties and maize growth. Organic amendments were applied at 10 Mg ha−1, and synthetic fertilizer was applied at the recommended rate of maize (N: P2O5: K2O at 60:60:40 kg ha−1). The results showed that addition of organic amendment significantly increased the total biomass parameter compared to the control, which ranged from 23.2% to 988.5%. The pure biochar treatment yielded lower biomass than the control by 27.1%, which was attributed to its low nutrient content. Consequently, the application of the co-composted biochar achieved higher plant height and aerial portion, which ranged from 46.86% to 25.74% and 7.8% to 108.2%, respectively, in comparison to the recommended fertilizer rate. In addition, the soil amended with co-composted biochar had a significant increase in soil organic matter and had significantly higher chlorophyll and nutrient concentrations in plants, which increased with an increase in the biochar ratio of the co-composts. This was probably attributed to the release of the nutrients retained during composting, thereby possibly making the co-composted biochar act as a slow-release fertilizer. In conclusion, the addition of organic manure with biochar enhanced the nutrient supply by gradual release in comparison to the mineral fertilizer.

1 RESUME L’objectif de l’étude a été d’évaluer l’effet des fréquences d’apport des engrais minéraux sur les variables de croissance, de développement, de précocité et de productivité des variétés de tomate en culture sous abri en saison pluvieuse. Trois doses, de NPK et d’urée ont été apportées sur les plants de variétés «Padama», «Thorgal» et «Tomy» de tomate dans un essai sous abri de mai à août 2014 en régime pluvial. Le dispositif expérimental était un split-plot avec 4 répétitions, ayant pour facteur principal les trois fréquences de fertilisation et le facteur secondaire la variété. Les observations et mesures ont porté sur la hauteur et le diamètre de la tige principale des plants, les dates de floraison et de nouaison, la hauteur d’insertion du 1er bouquet floral, les nombres de fleurs et de grappes à fruit par plant. Nos résultats ont montré que les plants issus d’un apport de NPK et d’urée toutes les trois semaines (F2) ont cru plus rapidement que ceux qui étaient sous F1 (2 semaines) et F3 (apport unique). De même, cette fréquence d’apport a induit une hauteur d’insertion plus élevé du 1er bouquet floral chez tous les cultivars. Toutefois il a été constaté une similarité des diamètres de la tige principale sous les trois fréquences d’apport pour chaque variété. L’apport unique (F3) et toutes les deux semaines (F1) d’engrais NPK et d’Urée, ont augmenté la préciosité chez toutes les variétés par rapport à l’apport toutes les trois semaines (F2). Aucunes différences significatives entre les trois traitements pour le nombre de bouquets floraux et de grappes à fruits n’ont été observées. Mineral fertilizers application frequencies: impact on the growth and development parameters of winter tomato under greenhouse in central Burkina Faso ABSTRACT The objective of the study was to evaluate the effect of mineral fertilizer input frequencies on growth, development, earliness and productivity variables of tomato varieties under rainy season cover crops. Three doses of NPK and urea were applied to tomato "Padama", "Thorgal" and "Tomy" seedlings in a shelter trial from May to August 2014 under rainfed conditions. The experimental design was a split-plot with 4 repetitions, with the main factor being the three frequencies of fertilization and the secondary factor the variety. Observations and measurements related to the height and diameter of the main stem of the plants, the dates of flowering and fruit set, the insertion height of the 1st floral bouquet, the numbers of flowers and fruit clusters per plant. Our results showed that plants fed with NPK and urea every three weeks (F2) grew faster than those under F1 (two weeks) and F3 (one application). Likewise, this feeding frequency induced a higher insertion height of the 1st floral bouquet in all cultivars. However, a similarity of the diameter of the main stem was found under the three delivery frequencies for each variety. The single (F3) and biweekly (F1) intake of NPK and Urea fertilizers increased the preciosity in all varieties compared to the intake every three weeks (F2). No significant differences between the three treatments for the number of flower bouquets and fruit clusters were observed.

The use of alternative sources such as biochar can contribute to sustainable agriculture. The objective of this study was to evaluate the effect of fertilization with biochar in combination with mineral fertilizer, growth rates and yield of sunflower cv. Embrapa 122/V2000. The experiment was carried out in a protected environment of UAEAg/CTRN/UFCG in pots with a capacity of 20 dm3 under a completely randomized experimental design, with treatments arranged in a factorial scheme (5 × 4) and four replicates corresponding to five doses of mineral fertilization 0, 25%, 50%, 75%, and 100% of fertilization indication with NPK (100, 300, and 150 mg kg-1) and four doses of biochar, 0; 5% (400 g/pot); 10% (800 g/pot) and 15% (1100 g/pot) calculated on the basis of the soil volume. Fertilization with biochar promoted an increase in sunflower growth rates in the evaluation periods. The combination of 50: 150: 75 mg kg-1 of NPK and 400 g/pot of biochar promotes higher production of sunflower (23.91 g/plant).

The Impact

The 28-day incubation experiment was carried out to evaluate the impact of the application of digestate (Dig); digestate with straw (DigSt); pig slurry (Slu) and mineral fertilizer (NPK) on Cd, Cu, Mn and Zn availability, on K<sub>2</sub>SO<sub>4</sub>-extractable carbon content and on the soil pH value in long-term contaminated soil. At days three and seven of the experiment, the 0.01 mol/L CaCl<sub>2</sub>-extractable fractions of Cd, Zn and Mn significantly decreased under organic treatments (Dig, DigSt and Slu) with the most pronounced effect under Dig treatment. The NPK treatment caused the increase of risky element concentrations since day 21 of incubation which was accompanied with pH decrease. The contents of 0.5 mol/L K<sub>2</sub>SO<sub>4</sub>-extractable carbon were the highest at day 3 and 7 of incubation in organic treatments. The significant correlations between 0.5 mol/L K<sub>2</sub>SO<sub>4</sub>-extractable carbon and CaCl<sub>2</sub>-extractable metal concentrations showed a close relationship between fresh organic matter added in organic fertilizers and risky element availability, suggesting that newly added labile organic matter can form temporary ligands with risky elements and release them later following its decomposition.

Maize Yields

Overuse of mineral fertilizer has become common at the North China Plain. Simultaneously, more organic manure resources are available for smallholder farmers. In order to increase the use of organic manure and reduce mineral fertilizer applications, a 10-year fertilization experiment with maize took place between 2008 and 2017. We assessed the long-term effects of cattle manure (CM) application and a complete nutrient substitution with mineral fertilizer (MF) at four application levels (3, 6, 9 and 12 t ha−1 CM) on yield, macronutrients (N, P and K) use efficiencies and soil conditions. Results showed that maize yields from CM and MF treatments differed across time and were significantly different in the first year of the experiment to no significant differences with increasing experimental time. In addition, increased MF levels did not result in increased maize yields; this response was different with CM applications. The highest 10-year maize average yield was 7.7 t ha−1 obtained with 9 t ha−1 of CM. Our results also showed that at the lowest application level (3 t ha−1 CM), the partial factor productivity (PFP) and the agronomic efficiency (AE) of all macronutrients were significantly higher with MF than with CM applications. Nevertheless, these differences narrowed with increased fertilizer input levels. The MF and CM recovery efficiency (RE) of N, P and K performed differently. Generally, MF exhibited significantly higher N-RE than CM treatments. CM treatments had significantly higher P-RE, but no K-RE differences were found between CM and MF. Soil available N, P and K significantly increased when fertilizer levels raised. MF treatments exhibited similar levels of soil available N, but lower soil available P and K compared with CM treatments.

AbstractBeninese smallholders associate food crops and cash crops with immature oil palms to reduce field maintenance costs and gain income before the palms reach productive phase. Little is known about the effects of these crops on the nutritional status and growth of the palms in their immature phase even though the yield of adult palms can be affected by the management practices during this phase. The objective of this study was to evaluate the most common oil palm-based intercropping systems found in southern Benin in terms of nutritional status and growth of the palm. Within 15 oil palm farms, we compared 15 immature oil palm fields where the crop succession associated with the oil palms was dominated by maize, cassava, tomato, and pineapple. The nutrient concentrations in the soil and the palm leaves, and growth indicators were measured at the end of the immature phase. We found that the palm growth indicators were the lowest in the successions with pineapple. N and P nutrition of the immature palms was satisfactory but K was deficient in all systems, especially in those with pineapple. The K levels in the soils and palm leaves were correlated. Rough field budgets comparing the amounts of N and K applied to the crop successions with their N and K exports from non-returning products indicated that soil indigenous K supply would be particularly depleted in the systems with pineapple. We concluded that the young oil palms were affected by the competition for K exerted by the crop successions with pineapple even though they were the most fertilized in the region. The high profitable crop is therefore associated with the lowest growth rates of the immature palms. The mineral fertilizer management in these oil palm temporary intercropping systems should be improved.
