Experiments were conducted for chemical management against panicle mite, Steneotarsonemus spinki using seven treatments. Based on the overall performance of chemicals against this pest, spiromesifen ~ propiconazole, diafenthuron ＋ propiconazole and fenpyroxymate alone were found effective against panicle mite and associated grain discolouration. Spiromesifen （1 mL）＋ propiconazole （l mL） per litre of water was the best treatment which recorded 24.77% increase in grain yield over control.

很多因素导致设计的复杂性增加，而且这种增长趋势还在继续。10年前，一个嵌入式系统平均只有100000行代码。到2001年，这个数字超过了100万，到今天，甚至远远超过500万。由于硅芯片变得越来越经济高效，开发人员正在转向32位微处理器单元（MPU）。市场研究公司Venture Development Corporation（VDC）的一项调查显示，在今后两年将有61％的被调查者采用32位MPU，因为硬件成本不再是决定性的因素。此外，嵌入式设计的需求在很多不同的应用领域都在增长。例如，多媒体正在促进更多面向数字信号处理系统的应用；汽车通信系统需要高性能的处理能力；工业机器和传感器需要嵌入式控制，这些需求使工程师和科学家，或领域专家，或非典型DSP开发人员，寻求不同的方法来对嵌入式系统编程。随着这些不断增长的复杂性，传统的嵌入式系统的开发方法已经不能满足需求。例如，基于文本的面向对象的设计工具不能提供有效的建模方法，尤其是在有时间和并行性要求的时候。

Aloe vera, a short-stemmed shrub is described as a “wonder plant”, due to its vast uses in various medical products. Since many decades, extensive research has revealed that the pharmacological active ingredients are distributed in both the gel and rind of the Aloe vera leaves. A. vera is very popular in cosmetic and pharmaceutical industries and it is needed in large quantities with higher fractions of important constituents. To satisfy the market demand, intervention of microbial community seems to be a promising approach, which helps to increase the growth and metabolites along with plant fitness. Piriformospora indica is a root colonizing endophytic fungus, having unique plant growth-promoting properties. It helps the plant to acquire more nutrients from soil even under extreme physical and nutrient stress conditions. It interacts with a wide range of hosts. Interaction of P. indica with A. vera resulted in overall increase in plant biomass and greater shoot and root length, as well as number of shoots and roots as compared to control under both in vitro and in vivo environment conditions. Apart from that, the photosynthetic pigments (Chl a, Chl b and total Chl) and aloin content were observed significantly higher in A. vera plantlets colonized with symbiotic endophyte. The antioxidant activities were also tested and found significantly higher as compared to control plants. This imparts the potential of P. indica, to resist the plants against phyto-pathogenic microbes. P. indica has been proved as a potential candidate to enhance the biomass production along with various value additions in the form of active ingredients in A. vera.

Black rice Oryza sativa is primarily grown in East and North East of India. This variety could not become popular due to low yield and being expensive. It is rich in three kinds of Anthocyanin contents which exhibit great impact on human health. Four different kinds of ZnO nanomaterial were prepared at variable temperature ranging from 250°C to 500°C. The Interaction of black rice grain with nanozinc material leads to the observation that seeds germinated early. Rooting development was higher. Better effects were observed while those interacted with nanomaterial prepared at 350°C. In the present study the aim was to enhance the yield and value addition. To best of our knowledge this is the first scientific attempt [see also patent filed varma et al. 2019]. The mechanism involved needs further elaborate elucidation. We hope that the goal can also be achieved by interaction of seeds with mycosymbiont—Piriformospora indica (Serendipita indica) a potent cultivable mycorrhiza. The precise objective of this communication is to illustrate the interaction of black rice seed with several synthesized nano zinc material which varied in shape, size and diameter.
