Pub Date : 2022-11-01 DOI: 10.47815/apsr.2021.10209
To evaluate the efficacy of salicylic acid in improving water productivity under different irrigation regimes, a field experiment was carried out in 2019-20 and 2020-21 in a split plot design with three irrigation regimes i.e., irrigation water (IW) to cumulative pan evaporation (CPE) ratios of 0.3, 0.6 and 0.9 in main plots and foliar spray of salicylic acid (SA) at four concentrations i.e., 0, 0.5, 1.0 and 1.5 mM in sub plots. Frequency of irrigation significantly affected the morphological and physiological traits. However, foliar application of salicylic acid alleviated the effect of less frequent irrigation on plant height (4.6-10.3%), biomass (10.4%) and leaf area (1.0%). SA application improved the water status of plants with 9.2% higher relative water content as compared to control. Root mass density was higher in I0.3 regime in the lower depths of soil profile as compared to I0.6 and I0.9, which further increased with salicylic acid application. The content of osmolytes was highest in I0.3 which increased up to 34-36% with salicylic acid. Highest seed yield was recorded under I0.6 regime and 1.5 mM SA but it was statistically at par with 1.0 mM SA. Water productivity was highest in the least irrigated regime (3.55 kg ha-1 mm-1) and 1.0 mM SA (3.25 kg ha-1 mm). Foliar application of 1.0 mM SA can be considered as the effective for improving seed yield under all irrigation regimes with more pronounced effect in less frequent irrigation regime.
为评价水杨酸在不同灌溉方式下提高水分生产力的效果,于2019- 2020年和2020- 2021年在三种灌溉方式下进行了田间试验,即主区灌溉水(IW)与累积蒸汽量(CPE)之比分别为0.3、0.6和0.9,子区叶面喷施浓度分别为0、0.5、1.0和1.5 mM的水杨酸(SA)。灌水频率对植株形态和生理性状有显著影响。然而,叶面施用水杨酸缓解了较少灌溉对株高(4.6-10.3%)、生物量(10.4%)和叶面积(1.0%)的影响。施SA改善了植株水分状况,相对含水量比对照提高了9.2%。根质量密度在I0.3处理下较深层土壤剖面中高于I0.6和I0.9处理,且随水杨酸的施用而进一步增加。在I0.3中渗透产物含量最高,添加水杨酸后渗透产物含量增加34-36%。籽粒产量在I0.6和1.5 mM SA下最高,但在统计上与1.0 mM SA相当。水分生产力在最少灌溉(3.55 kg ha-1 mM -1)和1.0 mM SA (3.25 kg ha-1 mM)条件下最高。在所有灌溉方式下,叶面施用1.0 mM SA均可有效提高种子产量,在灌溉频率较低的情况下效果更为显著。

An investigation carried out to standardize the pasteurization method for the extraction of maximum pulp/juice from guava and grapes and a process for development of anthocyanin rich guava nectar. The pulp of guava variety Allahabad Safeda and juice of coloured grape variety, Pusa Navrang was extracted and used in different proportions for optimization of blends of extracted pulp/ juice from both the fruits for preparation of anthocyanin rich guava nectar without deterioration of guava flavor. Among the different pasteurization methods in respect of irradiation, microwave with 600 W microwave power level, followed by pasteurization at 700C as thermal treatment, found to be the best methods for maximum recovery of the extracted pulp/ juice and nutritional quality over other methods. After pasteurization, the recovery of pulp 62.3%, TSS 14.42oB and ascorbic acid 193.0 mg/100ml was recorded in guava and whereas the juice recovery 68.7 %, TSS (20.53oB), ascorbic acid (6.76 mg/100ml) and anthocyanin content (38.38 mg/100ml) was recorded in coloured grapes, when the fruits were treated with 600 W microwave power level. However, in case of thermal pasteurization at 70oC the recovery of pulp 55.8%, TSS 12.4oB and ascorbic acid 149.33 mg/100ml was recorded in guava and juice recovery 63.0%, TSS (16.47OB), ascorbic acid (6.26mg/100ml) and anthocyanin content (33.48 mg/100ml) was recorded in coloured grapes. With regards to optimization of different blend proportions, for development of anthocyanin guava nectar, a blend of 50:50 of guava pulp and coloured grapes juice was found to be best proportion in preserving the colour, flavour, taste and overall quality of developed anthocyanin guava nectar with having guava dominant flavour.
为规范番石榴和葡萄最大限度提取果肉/果汁的巴氏灭菌方法和开发富含花青素的番石榴花蜜的工艺,进行了研究。以番石榴品种Allahabad Safeda的果肉和彩色葡萄品种Pusa Navrang的汁液为原料,提取不同比例的番石榴果肉和汁液,以制备花青素含量高、风味不变质的番石榴花蜜。在不同的巴氏杀菌方法中,微波功率为600 W的微波辐照,然后在700℃的高温下进行巴氏杀菌,与其他方法相比,可以最大限度地恢复提取的果肉/果汁和营养品质。经巴氏杀菌处理后,番石榴果肉回收率为62.3%,TSS为14.42oB,抗坏血酸为193.0 mg/100ml;彩色葡萄果汁回收率为68.7%,TSS为20.53oB,抗坏血酸为6.76 mg/100ml,花青素含量为38.38 mg/100ml。然而,在70℃的高温巴氏灭菌条件下,番石榴的果肉回收率为55.8%,TSS为12.4oB,抗坏血酸为149.33 mg/100ml,果汁回收率为63.0%,彩色葡萄的TSS为16.47OB,抗坏血酸为6.26mg/100ml,花青素含量为33.48 mg/100ml。通过对不同配比的优化,在番石榴花青素花蜜的开发中,发现番石榴果肉与彩色葡萄汁的配比为50:50的最佳配比,既保留了所开发的番石榴花青素花青素花蜜的色、香、味和整体品质,又具有番石榴的优势风味。

Feeding the ever-growing population has always been a daunting challenge to researchers, however on the contrary, itopened the floodgate of innovative technologies, especially of late, with the introduction of meta-genomics unfolding those genetic traits of microbes, which otherwise remained unexplored for a very long time.Learning negative consequences of previous green revolution in terms of various chronic environmental issues, phyto-microbiome analysis(microbiome bioprospecting)leading to identification of many plant growth promoting microbes, disease suppressive antagonists including entomopathogenic microbes and agrochemicals residues cleansing microbes,preferably in a bioformulation mode have evoked a very strong claim to be stitched into modern day agriculture, claimed close to chemical residue free organic as well as natural agriculture, a pre-requisite to stake claim for next green revolution. Such microbial interventions are likely to ensure three major paradigm shifts in agriculture viz., i. over-use of pesticides to residue free precision farming, ii. traditional to intelligent farming and iii.input-intensive (high cost of production) to climate- smart solutions, all collectively look forward towardsmore sustainable development of agriculture. All these issues have been systematically analysed through bibliometric evidences and envisioned the future course of action to realise yet another green revolution through microbial interventions.
养活不断增长的人口对研究人员来说一直是一个艰巨的挑战,然而,相反,它打开了创新技术的闸门,特别是最近,随着元基因组学的引入,揭示了微生物的遗传特征,这些特征在很长一段时间内都没有被探索过。了解以往绿色革命在各种慢性环境问题方面的负面影响,植物微生物组分析(微生物组生物勘探)导致许多植物生长促进微生物,疾病抑制拮抗剂,包括昆虫病原微生物和农药残留物清洁微生物的鉴定,最好是在生物配方模式下,已经引起了一个非常强烈的要求,要融入现代农业。声称接近无化学残留的有机和自然农业,这是下一个绿色革命的先决条件。这样的微生物干预可能会确保农业中的三个主要范式转变,即:过度使用农药到无残留精准农业;传统到智能农业和三。从投入密集型(高成本生产)到气候智能型解决方案,所有这些都共同期待着更加可持续的农业发展。所有这些问题都通过文献计量证据进行了系统分析,并设想了通过微生物干预实现另一场绿色革命的未来行动方案。

Such microbial interventions are likely to ensure three major paradigm shifts in agriculture viz., i. over-use of pesticides to residue free precision farming, ii. traditional to intelligent farming and iii.input-intensive (high cost of production) to climate- smart solutions, all collectively look forward towardsmore sustainable development of agriculture.

The goal of this study was to assess the toxicological effects of exposing popular variety of fenugreek [Trigonella foenum-graecum L.] to fluoride during the germination and early seedling stages. In January 2022, the experiment was carried out at Arunachal University of Studies, Namsai. Surface sterilized seeds of uniform size were set for germination in petri-plates over cotton beds, treated with fluoride solutions of varied strengths (0.0, 2.0, 4.0 and 6.0 mM), made from a stock solution of sodium fluoride (50.0mM). The results showed that fluoride might cause considerable phytotoxicity during germination and seedling growth. Fluoride administration resulted 13 to 43.10% suppression of germination from 2.0mM to 6.0mM. Similar results were also found in germination index, germination energy, relative germination rate and seedling vigor index which were significantly reduced by 43.1, 43.1, 34.0, and 84.0% in 150.0 mM, respectively. Fluoride also had significant detrimental impact on seedling length (71.78%) in the intact seven days with increasing doses of fluoride.
本研究的目的是评估在发芽和幼苗早期阶段将常见的葫芦巴[葫芦巴]暴露于氟化物的毒理学效应。2022年1月,该实验在南赛**研究大学进行。均匀大小的表面灭菌种子在棉花床上的培养皿中萌发,用不同强度的氟溶液(0.0,2.0,4.0和6.0 mM)处理,由氟化钠原液(50.0mM)制成。结果表明,氟在种子萌发和幼苗生长过程中可能产生相当大的植物毒性。在2.0mM ~ 6.0mM范围内,加氟抑制萌发率为13% ~ 43.10%。萌发指数、萌发能、相对发芽率和幼苗活力指数在150.0 mM处理下分别显著降低了43.1%、43.1%、34.0%和84.0%。随着氟处理剂量的增加,对幼苗长度也有显著的不利影响(71.78%)。

Available macronutrient status in the soil of Chotanahalli micro-watershed (468 ha) in Kunigal Taluk, Tumkur district was studied with the aid of GIS. Forty three surface soil samples at 320 m grid were collected from Chotanahalli micro-watershed and assessed for the soil organic carbon, available nitrogen, phosphorus, potassium, calcium, magnesium and sulphur. Results revealed that the ranges of SOC, available N, P and K were 2.1 to 7.5 g kg-1, 282.2 to 526.8 kg N ha-1, 8.0 to 67.6 kg P2O5 ha-1 and 124.3 to 338.5 kg K2O ha-1, respectively. Spatial interpolation revealed that majority (321 ha) of the watershed was low in SOC, whereas the whole watershed was medium in available N, P and K. In case of secondary nutrients, available S was found to be medium in majority (423.4 ha) of the area, whereas, exchangeable Ca and Mg were found sufficient in the whole watershed. The Nutrient Index values indicated that the micro-watershed was under “medium” category for available nitrogen, phosphorus, potassium and sulphur, whereas, it fell under “low” category with respect to organic carbon. Measures to improve the status of SOC should be taken up in the study area for sustainable production of crop.

An experiment was conducted during the Kharif season, of 2018 to study the effect of NCU in conventional and customized leaf colour chart (CLCC) based approach on rice (Oryza sativa). The eight treatments were evaluated in randomized block design with three replications. It has been found that application of NCU based on CLCC recorded higher yield i.e. by 7.74% in comparison with conventionally applied NCU and 12.5% in comparison with conventionally applied OU. The N2O emission ranged from 14.1–91.6 μg N2O-N m−2 hr−1 and the total N2O-N emission during the season ranged from 0.38 to 0.61 kg ha−1. The loss of N through N2O emission was recorded in the range of 19-23% under NCU applied based on CLCC than those applied under conventionally. 75% RDN in form of NCU based on CLCC recorded the highest N recovery efficiency (REN) (49.62%). CLCC based NCU application recorded notable performance in most of the yield attributing characters such as number of panicles m-2, panicle length, number of grains panicle-1, number of filled grains panicle-1 and harvest index. It also recorded the highest yield (4.59 t ha-1) amongst all the treatments and increases the yield by 7.74% in comparison with conventionally. The results acknowledged that N can be saved by following CLCC approach.
在2018年的哈里夫季节进行了一项试验,研究了NCU在常规和基于定制叶片颜色图(CLCC)的方法中对水稻(Oryza sativa)的影响。8个处理采用随机区组设计,3个重复。研究发现,以CLCC为基础的NCU的应用取得了更高的产量,即与传统应用的NCU相比,产量提高了7.74%,与传统应用的OU相比,产量提高了12.5%。N2O排放量为14.1 ~ 91.6 μg N2O- n m−2 hr−1,N2O- n总排放量为0.38 ~ 0.61 kg ha−1。与常规处理相比,基于CLCC的NCU处理通过N2O排放造成的N损失在19 ~ 23%之间。以CLCC为基础的NCU形式的75% RDN的氮素回收率(REN)最高,为49.62%。以CLCC为基础的NCU在穗数m-2、穗长、穗-1粒数、穗-1粒实数和收获指数等产量属性指标上均有显著提高。在所有处理中产量最高(4.59 t hm -1),比常规处理增产7.74%。结果表明,采用CLCC方法可以节省N。
