Soil health needs to be improved for the sustenance of a productive agriculture and sound environment where alley cropping system might play a vital role. The study was composed of two factors viz. three alley widths of Gliricidia sepium (3.0, 4.5 and 6.0 m), and five nitrogen levels (0, 25, 50, 75 and 100% of the recommended dose) along with pruned materials in a split-plot design with three replications. The soil chemical properties were examined in alleys of Gliricidia sepium tree over two consecutive seasons. Results displayed that pruned materials (PM) of G. sepium increased the soil pH, organic carbon (OC), total nitrogen (N), available phosphorus (P) and sulfur (S), exchangeable calcium (Ca), magnesium (Mg), potassium (K), and cation exchange capacity (CEC) of soil in different alley widths compared to the control. However, alley width 3.0 m and 100% N along with PM displayed the maximum OC (0.94%), total N (0.21%), available P (16.26 ppm), exchangeable Ca (2.54 meq/100 g) and Mg (0.90 meq/100 g), while maximum exchangeable K and CEC were noted in alley width 4.5 m and 100% N along with PM. The above results explicated that the improvement of the soil chemical properties by using pruned materials of G. sepium in alleys can be a promising option for uplifting the soil health condition as well as sustainable agricultural practices.

Abstract Low soil fertility is a major problem limiting peri-urban vegetable production in the Kumasi metropolis. This study was conducted to assess the effects of poultry litter biochar (PLB) and NPK fertilizer application on soil chemical properties and the yield of cabbage. Twelve treatments (control, 100% NPK, 50% NPK, 2.5 t ha−1 PLB, 2.5 t ha−1 PLB + 50% NPK, 2.5 t ha−1 PLB + 100% NPK, 5 t ha−1 PLB, 5 t ha−1 PLB + 50% NPK, 5 t ha−1 PLB + 100% NPK, 7.5 t ha−1 PLB, 7.5 t ha−1 PLB + 50% NPK, and 7.5 t ha−1 PLB + 100% NPK) were evaluated under field conditions in a randomized block design with three replications. Combined application of PLB and NPK fertilizer improved the soil chemical properties, growth, and yield of cabbage relative to the control and sole PLB treatments. Application of 5 t ha−1 PLB + 50% NPK increased the soil pH, soil organic carbon, available phosphorus, and cation exchange capacity by 26.6, 41.4, 296, and 78.7%, respectively, relative to the control. Moreover, 5 t ha−1 PLB + 50% NPK increased the cabbage yield by 73% compared with the control. This study concludes that PLB and NPK fertilizers can be applied to improve the soil chemical properties and yield of cabbage.

Currently, large oil palm plantations are cultivated on ultisol. Ultisol has various constraints in its utilization for the cultivation of plants, because it has high exchangeable Al, low pH, low soil organic nutrient contained, and soil nutrients such as N, P, K, Ca, Mg.  Large quantities and continuous fertilizer are needed for a long time. To solve these problems required to look for alternative fertilizers. These alternative fertilizers are expected to reduce the use of synthetic fertilizers without decreasing production and are available forever. Efforts to produce that location organic matter are the right choice. Tithonia can be grown in the form of alley cropping at young palm plantations. A series of experiments have been conducted at Andalas University experimental farm in Padang, West  Sumatra Province. This study used the Factorial design.  The treatments are tithonia compost and Lime application. There are 3 rd compost doses in 3 replication each treatment. The experimental obtained that tithonia compost dosage 25% and 50% + 25% and 50% synthetic fertilizer were changed soil chemical properties such as increased 0.94 units soil pH, availability of nutrient contained; 6.22% C-organic, 0.25% N-total, 0.37me/100g   exchangeable K, 2.74 me/100g exchangeable-Ca, 0.29 me/100g exchangeable-Mg, in the soil, as well as the decrease of exchangeable Al. Furthermore supporting plant growth such as (plant height, plant length,  and the number of the leaf).  Liming not significantly different for soil chemical properties and growth of oil palm. The higher the compost dose is given the better the growth of oil palms. Cultivation of tithonia as alley cropping at oil palm plantation  can be used as composite materials for synthetic fertilizer substitute source N and K

AbstractUse of organic manures to meet the nutrient requirement of crop would be an inevitable practice in the years to come for sustainable agriculture since organic manures generally improve the soil physical, chemical and biological properties. Hence, field experiments were carried out in 2017 and 2018 to compare the impact of different organic manures and NPK fertilizer on soil properties, growth, yield, proximate and mineral contents of okra (Abelmoschus esculentus L.). The treatments each year 2017 and 2018 consisted of: rabbit manure, cow dung, poultry manure, green manure [Mexican sunflower (Tithonia diversifolia Asteraceae)], pig manure, NPK 15-15-15 fertilizer applied at 120 kg N ha−1 and a control (no manure/ inorganic fertilizer). The seven treatments were laid out in a randomized complete block design with three replication. Organic manures and NPK fertilizer increased the soil organic matter (OM), N, P, K, Ca and Mg (NPK fertilizer did not increase OM, Ca and Mg significantly), growth, yield, minerals, protein, ash, carbohydrate and mucilage contents of okra fruit as compared with control. Organic manures improved okra yield compared with NPK fertilizer. Okra growth and yield parameters were significantly higher in 2018 compared with 2017. Control, rabbit manure, cow dung, poultry manure, green manure, pig manure and NPK fertilizer in 2018 increased the pod yield of okra by 9.7%, 35.3%, 57.9%, 36.2%, 39.2%, 45.5% and 3.2%, respectively compare with the same treatment in 2017. Amongst various organic manures, poultry manure produced significantly higher plant growth, yield, mineral and proximate composition of okra because of its high soil chemical properties which could be related to its lowest C: N ratio, lignin and lignin: N ratio. Results also showed that okra grown during high intensity rainfall has higher yield but with reduced quality except its mucilage content. Therefore, planting of okra with poultry manure under moderate rainfall will enhance the health benefit from the fruit, however, those that desire its mucilage content planting during high rainfall is recommended.
