“…Nitrogen fertilizer, either organic or inorganic, always affects vegetative growth of the fodder and cereals; and therefore, the increase in the application of liquid bioslurry and yield maximization of kale was in line with the results reported by Rahman et al (2008). Similarly, the increase in dry biomass of kale on the application of biogas slurry in combination of N inorganic fertilizer was in line with the results reported by Yu et al (2010). Moreover, observation and documentation made by Aktar et al (1996) and Souza et al (2008) are also supportive of the present findings who reported that when organic fertilizer is used in the soil, some metallic trace elements stimulated root growth that ultimately increases the dry biomass yield of kale crop.…”

Kale is one of the nutritious leafy vegetables with a high nitrogen fertilizer requirement. However, soil fertility is declining progressively due to the imbalanced use of inorganic fertilizer. Discharging bioslurry as waste will lead to environmental pollution and disposing will also lead to costs because of its large volume. Consequently, replacing chemical fertilizers with bio-slurry can not only achieve efficient resource utilization and disposal cost, but also reduce the amount of chemical fertilizer used and environmental pollution attributed by chemical fertilizers. Therefore, a pot experiment was conducted in a mesh house at Hawassa College of Agriculture to evaluate the combined effect of bio-slurry and inorganic nitrogen fertilizer for growth and yield performance of kale. Five combinations of liquid bioslurry and inorganic nitrogen fertilizer were used, that is, 25% bio-slurry + 75% nitrogen, 50% bio-slurry + 50% nitrogen, 75% bio-slurry + 25% nitrogen, 100% bio-slurry, 100% nitrogen and 0 use of either fertilizer source as a control. Data on phenology, growth and yield attributes were recorded. Results revealed that the treatment had significant effect on growth and yield attributes of kale. The highest (455.10 g) leaf fresh weight and fresh biomass (814.86 g) was obtained when 100% sole application of liquid bio-slurry was used. Based on these results, it can be concluded that application of 100% bioslurry can improve the production of kale in the study area.

“…This increase in plant height is due to the high nutrient concentrations and organic matter of the digestate (Table 7), in addition to the available nutrients in mineral fertilizer [18,19]. The number of Chinese melon leaves significantly increased (p < 0.05) with the addition of biochar and digestate compared to control.…”

Effect of Digestate and Biochar Amendments on Photosynthesis Rate, Growth Parameters, Water Use Efficiency and Yield of Chinese Melon (Cucumis melo L.) under Saline Irrigation

Abstract:Despite the recent interest in biochar and digestate as soil amendments for improving soil quality and increasing crop production, there is inadequate knowledge of the effect of the combination of biochar and digestate, particularly under saline irrigation conditions. A pot experiment with Chinese melon was conducted in a greenhouse, biochar (5%) and digestate (500 mL/pot) were used with and without the recommended mineral NPK (Nitrogen, Phosphorus and Potassium) fertilizer dose (120-150-150 Kg ha −1 ). The plants were irrigated with tap water (SL0) and 2 dS/m (SL1) NaCl solution. The growth, photosynthesis rate, water use efficiency (WUE) and yield of Chinese melon were affected positively when biochar was combined with digestate amendment, particularly under saline irrigation water with and without mineral NPK fertilizer. The maximum yield under normal water was obtained by digestate (SL0: 218.87 t ha −1 ) and biochar amendment combined with digestate (SL1: 118.8 t ha −1 ) under saline water. The maximum WUE values were noticed with the biochar and digestate combination under all water treatments (SL0: 32.2 t ha −1 mm −1 and SL1: 19.6 t ha −1 mm −1 ). It was concluded that digestate alone was more effective than the use of biochar, particularly with normal water. The combination of biochar with digestate had a significant effect on the Chinese melon growth, photosynthesis rate, water use efficiency and yield under saline irrigation, and it can be used as an alternative fertilizer for mineral NPK fertilizer.

“…Similarly, after decomposition biogas slurry improved the fertility of soil by providing the N, P, and K, total N and P (Moler and Stinner, 2009;Urselmans et al, 2009;Yu et al, 2010), with more microbial activity that results into more root proliferation and water uptake, which in turn had increased yield attributing characters of rice and wheat crop in treatment receiving biogas slurry. Increased crop production with use of gypsum (Hussain et al, 2001;Ghafoor et al, 2001), et al, 2001) and biogas slurry (Ahmad et al, 2014;Ahmad et al, 2015) in salt affected soil has been reported earlier, which reinforced the findings of this study.…”

“…There are several evidences supporting the fact that the productivity of agricultural land can be increased dramatically with the use of manure produced from biogas (Krishna, 2001). Therefore, using biogas slurry is, generally, seen as an important issue for improving the soil health and sustainability of agricultural land (Yu et al, 2010). Hence, biogas slurry application is a practicable strategy for improving the physical and chemical properties of soil and nutritional quality of crop production in sustainable agriculture (Ding et al, 2011 (Singh et al, 1981;Ghafoor and Muhammad, 1981).…”

ABSTRACT. Amelioration of salt-affected soils requires an integrated management approach, which not only improves their effectiveness for improving soil properties, but also increases the crop production and quality of the produce. Hence, a study was planned to evaluate combined use of organic and inorganic amendments for better rehabilitation of salt affected soil in ricewheat cropping sequence from 2013 to 2016. Treatments included T 1 -control, T 2 -gypsum @ 100 SGR, T 3 -CaCl 2 @ 50% SGR, T 4 -CaCl 2 @ 50% SGR + biogas slurry @ 10 tˑha for wheat (Inqlab-91) and 110-90-60 NPK kg ha -1 for rice (Shaheen Basmati) was applied. Soil samples were collected before application of amendment and after harvesting of each crop. Straw and grain/paddy yield data were recorded at maturity. Pooled data showed that grain/paddy and straw yield of wheat and rice crop was higher in T 2 (gypsum @ 100% SGR), but statistically (P≤ 0.05) non significant with T 4 (CaCl 2 @ 50% SGR + biogas slurry @ 10 tˑha -1 ). T 3 (CaCl 2 @ 50 % SGR) was at par with T 6 (H 2 SO 4 @ 25% SGR + biogas slurry @ 10 tˑha -1 ), followed by T 5 (H 2 SO 4 @ 25% SGR). The minimum yield was recorded in T 1 (control). Soil analysis showed that pH s , EC e and SAR were significantly decreased in T 2, (Gypsum @ 100% SGR), followed by T 4 (CaCl 2
