“…The favourabe effect of organic materials (MMS and ML) may be to the positive effect of these materials on soil reaction and increasing the available moisture content and hence increasing the availability of P in the soil solution and it increases microbial population and P immobilization. This finding agreed with those obtained by Rady et al (2015) ; Sinegani and Mahohi (2009) ;Adekiya et al (2017) and Merwad, (2017).…”

“…(Undie et al, 2013 andMerwad, 2015b). Adekiya et al, 2017 found that addition of various green manures i.e., pawpaw, neem leaves and moringa leaves increased soil organic matter, yield and nutrient accumulation of okra compared with the control. The aim of the present work is to study the change in soil pH, available N, P and K during various incubation periods as well as yield and nutrients uptake by wheat plants as affected by moringa oleifera residues , MOR (leaves and meal seed as ML and MMS, ) added at different rates to sandy and calcareous soils.…”

“…As for application rates of moringa, results show that the average values of available nitrogen increased with the increasing application rates of MOR at different periods in sandy and calcareous soils .These results could be attributed due to the higher content of total nitrogen in high rate (15 Mg ha -1 ) of residues. Moringa has been reported to possess wide adaptations and high nutrients composition in its biomass (Bosch, 2004 ;Merwad, 2015b, Merwad, 2017Rady et al, 2015Adekiya et al , 2017 ;Desoky et al, 2017 ;Wang et al, 2017 andOladeji et al, 2017. As for incubation periods, results reveal that available nitrogen increased up to 90 days from incubation and then decreased in sandy soil, while in calcareous soil, the values were decreased at 90 days and then increased again up to 120 days from incubation . This trend was found true for MMS and ML residues.…”

Using organic substances i.e. Moringa oleifera residues (MOR) as soil conditioners is an important management strategy that can improve and uplift soil-quality properties and alter the nutrient cycling through mineralization or immobilization. Two experiments were conducted to study the effect of MOR i.e. leaves (ML) and meal seed (MMS) at a rate of 5, 10 and 15 Mg ha -1 on soil pH, available N, P and K content during various incubation periods as well as yield and nutrient uptake of wheat (Triticum aestivum L cv., Sakha 93) plants grown on sandy and calcareous soils. Soil pH values decreased with increasing application rates of MOR at different periods in the two tested soils. Soil pH values were lower with addition of MMS residues treatment than with ML. The highest values of available N, P and K were found in the tested soils when treated with 15 Mg ha -1 of MMS followed by 15 Mg ha -1 of ML at different periods. While the lowest ones were obtained with untreated soils followed by 5 Mg ha -1 ML. Available N was showed a highest increase after 90 days of incubation for the sandy soil and after 120 days for calcareous soil under application of MOR. Available P and K contents were increased gradually up to 120 days and then decreased for the two soils. The highest values of yield, biological yield, 1000-grain weight, protein content, straw and grain yields as well as N, P and K uptake of wheat were found in the tested soils owing to treated with15 Mg ha -1 of MML followed by 15 Mg ha -1 of ML.

“…Okra yield responses to organic and inorganic fertilizers have been reported by several workers [4], [8], [2], [9], [10] . However, since organic and in organic fertilizers contain different chemical composition and quality they therefore may react differently when applied to the soil with respect to soil chemical properties, crop yield and quality.…”

28Use of organic manures to meet the nutrient requirement of crop would be an inevitable practice 29 in the years to come for sustainable agriculture since organic manures generally improve the soil 30 physical, chemical and biological properties. Hence, field experiments were carried out in 2017 31 and 2018 to compare the impact of different organic manures and NPK fertilizer on soil properties, 32 growth, yield, proximate and mineral contents of okra (Abelmoschus esculentus L.). The 33 treatments each year 2017 and 2018 consisted of: rabbit manure, cow dung, poultry manure, green 34 manure [Mexican sunflower (Tithonia diversifolia Asteraceae)], pig manure, NPK 15-15-15 35 fertilizer applied at 120 kg N ha -1 and a control (no manure/ inorganic fertilizer). The seven 36 treatments were laid out in a randomized complete block design with three replication. Organic 37 manures and NPK fertilizer increased the soil organic matter (OM), N, P, K, Ca and Mg (NPK 38 fertilizer did not increase OM, Ca and Mg significantly), growth, yield, minerals, protein, ash, 39 carbohydrate and mucilage contents of okra fruit as compared with control. Organic manures 40 improved okra yield compared with NPK fertilizer. Okra growth and yield parameters were 41 significantly higher in 2018 compared with 2017. Control, rabbit manure, cow dung, poultry 42 manure, green manure, pig manure and NPK fertilizer in 2018 increased the pod yield of okra by 43 9.7%, 35.3%, 57.9%, 36.2%, 39.2%, 45.5% and 3.2%, respectively compare with the same 44 treatment in 2017. Amongst various organic manures, poultry manure produced significantly 45 higher plant growth, yield, mineral and proximate composition of okra because of its high soil 46chemical properties which could be related to its lowest C: N ratio, lignin and lignin: N ratio. 47Results also showed that okra grown during high intensity rainfall has higher yield but with 48 reduced quality except its mucilage content. Therefore, planting of okra with poultry manure under 49 moderate rainfall will enhance the health benefit from the fruit, however, those that desire its 50 mucilage content planting during high rainfall is recommended. 51

Cauliflower (Brassica oleracea L. var. botrytis L.) is as an important ingredient in many healthy diets worldwide, but there is a lack of scientific knowledge about fertilizer management during cauliflower production. We conducted field experiments in Yuzhong, China, in 2015 and 2016 to determine the effects of the integrated use of biofertilizer and a reduced rate of mineral fertilizers on cauliflower growth, quality, and yield and on soil characteristics. Three different rates of mineral fertilizer (60, 80, and 100% of the mineral fertilizers; 100% rate = 400 N kg ha −1 , 225 kg P 2 O 5 ha −1 , 125 kg K 2 O ha −1 ) and 500 kg ha −1 biofertilizer were applied to the crop with three replicates. The results showed that the use of the mineral fertilizer at 80% in combination with biofertilizer (80% BF) increased the vitamin C content of cauliflower heads by 39.5% in 2015 and 43.6% in 2016 compared with the 100% mineral fertilization treatment (100% MF). The 80% BF treatment decreased the nitrate content by 27.1% in 2015 and 27.6% in 2016 and improved the soluble sugar contents by 19.1% in 2015 and 29.5% in 2016 compared with the 100% MF treatment. However, the effect of the 80% BF treatment on marketable yield was found to be nonsignificant. Biofertilization also improved the soil organic matter, available N, P, and K, and enzyme activities. We observed that conjugative use of biofertilizer and a reduction in mineral N-P-K fertilizer can be used successfully in cauliflower production without compromising marketable yields.
