Abstract

For raising artificial plantations of Calamus tenuis, sowing the whole fruits within ten days of collection in the nursery and tending them for two years before transplanting in the field, gives best results. Application of fertilizers after transplanting has no significant effect either on the growth of plants, numbers of suckers they produced after four years of growth or the survival percentage.

Abstract

Ginseng is a famous Chinese drug used as Panacea and aphrodisiac by Chinese from time immemorial. The principa1 source of Chinese, American and Japanese Ginseng are the tuberons ischolar_mains of Panax ginseng, P. quinquefolius and P. japonicus respectively. Atleast three species, P. pseudoginseng, P. sikkimensis and P. bipinnaatifida, which are distributed in Eastern Himalaya, are the sources of Indian Ginseng. As the well known medicinal product Sanchi of China, used for treating various ailments including cancer, is prepared from P. pseudnginseng the cultivation of the species should be undertaken in East Himalayan region between 1,000 and 2,000 m of altitude. Indian Ginseng species are endongered and should be protected.

Abstract

Valeriana officinalis Linn, is the source of true valerian and an essential oil, well known in drug trade for use in medicine and an a perfume. It is in fairly good demand in India but does not appear to be cultivated anywhere in the country on commercial scale. The requirement is, therefore, met through imports for which no figures are avai1able. True valerian oil is one of the very costly essential oils; priced Rs 2000/per kg approximately, which is prohibitive and restricts its free use. Instead, the Inferior Indian valerian from Valeriana jatamansi Jones. syn. V. wallichii DC is used as a substitute. In order, therefore, to meet the country's requirement and to save the foreign exchange, the necessity of cultivating a suitable strain of Valeriana officinalis, was felt. Accordingly, seeds of an exotic strain of V. officinalis (from U.S.S.R.) were procured and trials were undertaken in Chakrata Hills (alt. 2150 m), District Dehra Dun, India. The results of cultivation and exploitation are mentioned. Also, the yields of rhizomes/ischolar_mains ,(valerian) and their oil content alongwith its physico-chemical constants, are given.

Abstract

Benign prostatic hyperplasia (BPH) is common in elderly males. However, benign mesenchymal tumors, especially pure leiomyoma, are rare in prostate. The diagnosis of is important because of the potential of malignancy in such cases, histopathology is only tool to diagnose and to rule out the malignant changes. Here we report the case of pure leimyoma prostate diagnosed on sonography as benign prostatic hyperplasia.

Abstract

A study of the possible correlation between kink-band,.jointing and drainage patterns in the Chamba nappe (Himachal Himalaya) shows a correspondence between the valley trends and the joints, indicating a neotectonic control of both features. However, no correlation exists between the Precambrian to Upper Paleozoic conjugate kink-bands and the present joint/valley orientations, showing that there was a fundamental change in the tectonic pattern between the Upper Palaeozoic and the recent ongoing crustal adjustment in the Himachal Himalaya.

Abstract

The Antagonistic fungi, viz., Trichoderma harzianum, T. viride, Gliocladium virens, Absidia cylindrospora Alternaria alternata and Fusarium solalli were evaluated against Sclerotinia sclerotiorum causing chickpea stem rot. T.harzianum and A.cylindropora were most effective in inhibiting the mycelial growth in dual cultures. Inhibitory activity of autoclaved culture filtrates was much less as compared to filter-sterilized culture filtrates. Culture filtrates of T.harzianum, G. virens and T. viride were particularly effective in inhibiting sclerotial germination. In pot culture experiments, wheat bran-saw-dust-tap water (1:1:6;W/W/v) mixture was most effective in reducing seedling mortality. Application of antagonists in Sclerotinia - sick plots reduced the disease incidence and increased yield over control. T.harzianum was most effective followed by G. virens and T. viride.

Abstract

Integrated effect of biocides and fungicides on sclerotlal germination of Sclerotinia seleratiorum (Lib.) was studied under in vitro conditions. MBC and Bayleton reduced sclerotial germination with an increase in dipping duration at higher concentration. At 100 μg/ml, ten and twenty min. dipping in MBC and Bayleton respectively, caused complete inhibition of sclerotlal germination. Complete kill of sclerotia was obtained with MBC at 5 μg/ml with 10 min. dip and 4 × 10⁸ spores/ml of Trichoderma harzianum Rifai whereas 15 min. dip was required for the same effect with Bayleton. A combination of presoaking, high temperature, treatment with MBC and Bayleton and three biocontrol agents significantly reduced sclerotlal viability. Complete inhibition or sclerotial germination was obtained with T. harzianum and Gliocladium roseum with the highest spore density(4 × 10⁸ spores/ml) at 50 and 55 °C.

Abstract

White rot of pea caused by Sclerotinia sclerotiorum (Lib.) is a serious menace in Kangra valley of Himachal Pradesh. The pathogen is polyphagous and soil borne, therefore, difficult to control through fungicides and host resistance. Because of the limitations in the use of fungicides as well as to minimize the pollution hazards, use of fungal antagonists as biocontrol agents against S. sclerotiorum was deemed very important. Keeping in view these aspects, present investigations were, undertaken.

Abstract

Identification of seismic events from continuously recorded seismic data in real-time through a Digital Seismic Data Recording system is a difficult task. Despite the vast amount of research in this field, the signal processing and event parameters discrimination algorithms have not yet fully come of age. Presently, we have a wide spectrum of trigger algorithms, ranging from a very simple amplitude threshold type to the sophisticated ones based on pattern recognition approaches. Some of the other approaches use adaptive technique and neural network methods. Researchers are continuously making efforts for the development of algorithms using various techniques, which produce minimum false trigger. Some approaches have been reported which are accurate for detecting first phase of events and take minimum possible computational time. In this paper several approaches for detecting event signals in background noise are presented and their precision evaluation is discussed.

Fifteen combinations of three French bean varieties viz., Arka Komal (V₁), Swaran Priya (V₂) and Contender (V₃) and five fertilizer levels (F₁- 20:40:40:20kg/ha NPKS; F₂- 40:40:40:20kg/ha NPKS; F₃ - 60:60:60:40kg/ha NPKS; F₄ - 80:60:60:40kg/ha NPKS, and F₅ -100:80:80:50kg/ha NPKS) were tested in factorial Randomized Block Design, with three replications. Among the varieties, Swaran Priya was superior for growth attributes, yield attributes and yield. Among fertilizer levels, F₅ (100:80:80:50kg/ha NPKS) resulted in highest growth parameters, yield parameters and yield of pods. Economic evaluation showed that variety Swaran Priya under F₅ (100:80:80:50kg/ha NPKS) resulted in maximum gross returns, net returns and cost:benefit ratio for green pod production.

Abstract

In 1987 Koblitz and Miller first proposed public key cryptosystems using the group of points of an elliptic curve over a finite field. The security of these cryptosystems was based upon the presumed intractability of the problem of computing logarithm in the elliptic curve group. Now we propose a new cryptosystem over elliptic curves whose security is based on expressing a torsion point in terms of the basis points. Since latter is more complicated than solving ECDLP. Consequently our cryptosystem is more secure than all cryptosystems based on ECDLP.

Abstract

Rhizoctonia solani, causal agent of banded leaf and sheath blight (BLSB) is widely distributed in the India in maize causing severe yield losses. In this study, a set was obtained by crossing ten QPM inbred lines in 10 × 10 diallel fashion (excluding reciprocals). In total sixty lines including parents, F₁'s, procured hybrids and standard check (HQPM-1 and Vivek QPM-9) were evaluated against banded leaf and sheath blight of maize under field conditions and artificial conditions during kharif 2016 and 2017, respectively. Data on reaction of maize genotypes to banded leaf and sheath blight under natural epiphytotic conditions revealed that the six parents viz., CML161, CML189, BAJIMQ-08-27, CML193, CML162 and CML171, one hybrid HQPM-7, one QPM check Vivek QPM-9 and forty one crosses were found to be moderately resistant. Under artificial epiphytotic condition thirteen crosses viz., BAJIMQ-08-27 × CML162, BAJIMQ-08-27 × CML161, CML162 × CML161, CML163 × CML161, CML170 × CML163, BAJIMQ-08-26 × CML171, CML193 × BAJIMQ-08-27, BAJIMQ-08-26 × CML161, CML193 × CML161, BAJIMQ-08-26 × CML163, BAJIMQ-08-27 × CML171, CML180 × CML161 and CML189 × CML163 showed moderately resistant reaction to BLSB; however, one cross was found susceptible (CML180 × BAJIMQ-08-27). These lines identified to possess low disease incidence score against BLSB in the present study could be used successfully in developing genotypes having desirable level of resistance in disease endemic areas to aim for sustainable productivity.
