摘要

研究了牛尿作为生物肥料和生物农药的利用效果,并与化肥和化学农药进行了比较。3组采用完全随机设计(CRD)进行实验。对照组(T0)不使用化学/生物农药和/或化肥。第二组(T1)按推荐剂量施用化肥和农药。第三组(T2)是用牛尿作为生物肥料和生物农药,按计算剂量施用。21天后,将发芽的水稻植株BINA boro水稻(品种28)转移到准备好的稻田。以牛尿为生物肥料,对稻田进行了预处理。将牛粪与牛尿(1:1)混合配制成生物肥料溶液,再加水稀释成1:9。将1公斤新鲜印楝叶放入10升装牛尿的容器中发酵28天。同时,将1升印楝叶提取液与10升淡水按1:10的比例混合,制成生物农药。牛尿作为生物肥料,在水稻生产中每公顷施用1000升,从移植到收获每28天重复施用一次。在水稻生产中,从种植到开花每隔15天用喷嘴喷洒1200升生物农药。同样,化学农药每隔7天施用一次。以株高、叶绿素含量、分蘖/丘数和籽粒产量分别作为生长和产量参数。第45天和第30天,T2的株高和叶绿素含量最高,分别为76 cm和46.5,但每山有效分蘖数最高,最终得分为14。对于所有处理,平均产量都是相同的。T2籽粒产量最高,为5.85 t/ha。在产量参数方面,化肥与化学农药(T1)组和生物肥料与生物农药(T2)组差异不显著,但在害虫侵害方面,生物肥料与生物农药(T2)组差异较低。第9卷第2期,2022年8月:165-169

Application of Cow Urine as Bio-Fertilizer and Bio-Pesticide In Boro Rice Production of Bangladesh
This study focused on cattle urine utilization as bio-fertilizer and bio-pesticide and its effectiveness on boro rice production comparing with chemical fertilizer and chemical pesticides. Three groups were divided into completely randomized design (CRD) to conduct the experiment. No chemical/bio pesticides and/or fertilizers is being applied in the control group (T0).The second group (T1) is being applied by chemical fertilizer and pesticides in recommended dose. The third group (T2) is being applied by cattle urine as biofertilizer and bio-pesticides in calculative dose. The germinated rice plant BINA boro rice (variety 28) was transferred to a well-prepared rice field after 21 days. The rice field was prepared using cow urine as bio fertilizer. The bio fertilizer solution prepared from mixing cow dung with cow urine (1:1) and then the solution was diluted into1: 9 with water. One kg of fresh neem leaves were kept in 10 L (liters) container with cow urine and allowed 28 days for fermentation. Meanwhile, one liter of the solution extracted from neem leaves was mixed with 10L of fresh water in a ratio of 1:10 to produce a bio pesticide. Cow urine as bio-fertilizer was applied one thousand liters per hectare in boro rice production which was repeated every 28 days from transplant to harvest. Bio pesticide was applied one thousand two hundred liters per hectare by nozzle spraying at 15-day intervals from planting to flowering in boro rice production. Likewise the chemical pesticide was being applied at seven-day intervals. Plant height, chlorophyll content, number of the tiller/hill and grain yield was observed as growth and yield parameter respectively. The tallest plant height and chlorophyll content were 76 cm and 46.5 from T2 on day 45 and 30 respectively, but number of effective tiller per hill, the maximum final score was 14 fromT1.For all treatments, the mean production became identical. However, T2 delivered the highest grain yield at 5.85 t/ha. In yield parameter chemical fertilizer and chemical pesticide (T1) and bio fertilizer and biopesticide (T2) group was non-significant, but in pest infestationbio fertilizer and biopesticide (T2) group was lower.
