Abstract
Field experiments were conducted during the winter season of 2016/17 and 2017/18 to assess the effect of biochar application in combination with different nutrient sources on cauliflower (Brassica oleraceae var. botrytis) production in sandy loam soil. The experiment was conducted using a Randomized Complete Block Design (RCBD) with ten different treatment viz., Farmer’s practice as control treatment, Recommended dose of fertilizer (200:120:80 kg NPK/ha), Composted biochar @ 1t/ha, Urine Soaked biochar @ 1t/ha, Mineral fertilizer (200:120:80 kg NPK/ha) mixed biochar @ 1t/ha, Humic acid soaked biochar @ 1 t/ha, Composted biochar @ 2t/ha, Urine Soaked biochar @ 2t/ha, Mineral fertilizer (200:120:80 kg NPK/ha) mixed biochar @ 2t/ha and Humic acid soaked biochar @ 2 t/ha, each replicated for three times. The application of biochar in combination with mineral fertilizers significantly increased the yields of cauliflower in both consecutive years. Application of biochar @ 2 t/ha along with mineral fertilizer at recommended dose increased curd yield of cauliflower by 37 % compared to that of only mineral fertilizer application and by 59 % compared to that of control treatment. Biochar and inorganic sources of nutrition together in soil showed superiority over other practices and would be of immense value to increase the productivity of cauliflower.
在2016/17和2017/18冬季进行了田间试验,评估了生物炭与不同营养源组合施用对砂壤土菜花(芸苔科品种)生产的影响。试验采用随机完全区组设计(RCBD),采用10种不同的处理方法,即农民实践作为对照处理,推荐施肥剂量(200:120:80 kg NPK/ha),堆肥生物炭@ 1t/ha,尿液浸泡生物炭@ 1t/ha,矿物肥(200:120:80 kg NPK/ha)混合生物炭@ 1t/ha,腐植酸浸泡生物炭@ 1t/ha,堆肥生物炭@ 2t/ha,尿液浸泡生物炭@ 2t/ha,矿物肥(200:120:80 kg NPK/ha)混合生物炭@ 2t/ha和腐植酸浸泡生物炭@ 2t/ha,每次重复施用3次。生物炭与矿质肥配施可连续两年显著提高菜花产量。2吨/公顷的生物炭与推荐剂量的矿物肥一起施用,与只施用矿物肥相比,花椰菜凝乳产量提高了37%,与对照处理相比,提高了59%。生物炭与无机营养源在土壤中结合施用具有明显的优越性,对提高菜花产量具有重要的价值。
