The present investigation conducted on grafting in brinjal during monsoon season of 2018 with the major objectives of this investigation to study the compatibility of brinjal varieties and suitable time for grafting when grafted on Solanum torvum at four different dates. The observation of scion rootstock was recorded before and after grafting. The variety Phule Arjun were reported minimum days to germination, days taken to reach grafting stage and highest germination percentage when sowed for 1st September grafting dates. It also reported the minimum days taken to graft healing, days to sprouting and transplanting when grafted at 1st August. Significantly highest grafting success was noted in Phule Arjun and Krishna grafted at 1st August and 1st September. Whereas, it was lowest recorded in Phule Harit grafted at 15th July. From the results obtained can be concluded that Phule Arjun and Krishna more compatible with Solanum torvum when grafted at 1st August and 1st September took minimum days for graft healing, sprouting, transplanting and highest grafting success.

Use of silver and silver salts is as old as human civilization but the green synthesis of silver nanoparticles (Ag NPs) has only recently been recognized. AgNPs were synthesized using aqueous extract of neem leaves and silver salt. The synthesized AgNPs were characterized using particle size analyser, UV-visible spectroscopy, XRD, SEM and AFM. The size of AgNPs was found to be within the range of 20-60 nm. The absorbance peak was in the range of 420-450 nm. SEM and AFM analysis showed that, the synthesized AgNPs are spherical in shape and surface roughness is 20.40 nm. Further the XRD analysis confirms the nano crystalline phase of silver with cubic crystal structure nature. The EDS analysis confirmed the presence of silver nanoparticles. AgNPs were specifically used in agriculture and medicine as antibacterial, antifungal and antioxidants. Antibacterial activity of synthesized AgNPs was carried out for both gram positive and gram negative bacteria and compared with standard silver nanoparticles. Hence, AgNPs could be use in the food and agricultural filed for commercial usage.

A field experiment was conducted during the months of November-January 2018-19, at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat to study the effect of foliar application of zinc on growth and yield of garden pea (Pisum sativum L.) with five different treatments and four replications. Among the various treatments, the highest plant height (59.15cm) and number of branches (11.60) were recorded with T4 (0.75% Zn), followed by T3 (0.50% Zn). T3 also recorded the highest fresh weight (39.30g) and dry weight (9.08g) of the plant a harvest as well as highest root weight per plant (0.73g). In case of yield attributing characters, the highest weight of the pod (6.63g), number of seeds per pod (7.59), weight of the seeds per pod (3.65g), shelling percentage (55.60%) and pod yield (56.31g/plant; 14.74t/ha) were recorded in case of T3 (0.50% Zn). However, the highest number of pods per plant (15.80) was recorded with T2 (0.25% Zn), which was very closely followed by T3 (0.50% Zn). In many instances the trend decreases after a particular point, due to negative effect of excess micronutrient application than the optimum amount needed, which affects the plant in various ways. In a broader view, it can be suggested from the present study, that the one with 0.50% zinc application (T3) turns out to be the optimum treatment, beneficial towards improving the growth and yield attributing characters.

Haematological parameters are useful tools for assessing health status of an animal. In Arid region of Rajasthan where sheep rearing is commonly practiced as pasture graze system, gastrointestinal parasitic infections are more frequent. So the present study was designed to evaluate the effect of Giloy and Neem alone and in combination on harmatological parameters of Marwari lambs and gastrointestinal parasitic load in treated animals compare to control group under arid zone. An experiment was conducted for 12 weeks on 42 Marwari male lambs and divided into seven groups, six lambs in each group in a randomized block design. The lambs of T1 group were provided only basal diet (grazing + ad lib. fodder + 400 g concentrate per lamb per day) and were kept as control group and lambs of all other treatment groups were provided basal diet with herbal supplementation i.e. 0.5 per cent Giloy stem powder in group T2, 1.0 per cent Giloy stem powder in group T3, 0.5 per cent Neem leaf powder in group T4, 1.0 per cent Neem leaf powder in group T5, 0.25 per cent Giloy stem powder along with 0.25 per cent Neem leaf powder in group T6 and 0.5 per cent Giloy stem powder along with 0.5 per cent Neem leaf powder in group T7. Higher level of Hb and PCV were recorded in different treatment groups than control group though, they were within normal physiological range but the effect was non-significant. Results of parasitic infection showed significant difference in the infection rates among the treatment groups and group T7 have minimum parasitic infection compared to other treatment groups. At the end of experiment it appears that incorporation of 0.5 per cent Giloy stem powder along with 0.5 per cent Neem leaves powder can be used as a part of strategy as they are effective to control gastrointestinal parasitic infection and maintain the value of Hb and PCV which indicate good health status of lambs in arid zone of Rajasthan.

Finger Millet (Eleusine coracana L. Gaertn.) is a widely grown millet crop in Southern Karnataka, it is attacked by various fungal, bacterial and virus pathogens, among them foot rot disease caused by Sclerotium rolfsii is a leading constraint for the farmers under both irrigated and rainfed conditions. For the management of this problem an eco-friendly approach was taken up in laboratory condition using chitosan and biocontrol agents, as they are known to have spin-off benefit of active innate defence mechanisms and promoting higher yields. In the research, chitosan of nine different concentrations were selected among them 0.15%, 0.20% and 0.25% showed the maximum inhibition of the pathogen. Along with chitosan, bio-agents viz., Trichoderma harzianum and Pseudomonas fluorescens were evaluated against Sclerotium rolfsii for their synergistic effect by well diffusion technique and it exhibited a positive effect on the inhibition of the pathogen showing the effectiveness in reducing the disease and chitosan not showing deleterious effect on bio-agents.
手指谷子(Eleusine coracana L. Gaertn.)是卡纳塔克邦南部广泛种植的谷子作物，它受到各种真菌、细菌和病毒病原体的侵袭，其中由罗尔夫氏菌核菌引起的脚腐病是灌溉和雨养条件下农民的主要制约因素。为了解决这个问题，在实验室条件下采用了一种环保的方法，使用壳聚糖和生物防治剂，因为已知它们具有积极的先天防御机制和促进更高产量的附带效益。研究中选择了9种不同浓度的壳聚糖，其中0.15%、0.20%和0.25%的壳聚糖对病原菌的抑制作用最大。利用孔扩散技术评价了生物制剂哈茨木霉和荧光假单胞菌与壳聚糖对罗氏菌核菌的协同作用，结果表明，生物制剂对哈茨木霉和荧光假单胞菌具有良好的抑菌效果，具有一定的降病效果，壳聚糖对生物制剂无有害作用。

In order to assess the genetic diversity of coriander and determine the traits effective on seed yield, twenty-eight coriander ecotypes which different provinces of India were evaluated based on morphological traits. Mahalanobis D2 statistics of multivariate analysis is recognized as a powerful tool in quantifying the degree of genetic divergence among the populations and to identify suitable donors for a successful breeding programme, as it measures forces of differentiation at intra and inter cluster levels. The D2 analysis indicated presence of ample genetic diversity among the genotypes studied, which were grouped into five clusters through Mahalanobis D2 statistics. The maximum inter cluster distance was observed between cluster IV and V (D2 = 471.83). The maximum intra cluster distance was observed within cluster IV (D2 = 36.48) which included five genotypes followed by cluster III (D2 = 11.37) which included eight genotypes. Therefore, the genotypes belonging to these different clusters may be undertaken in a hybridization programme for getting better segregants.

The finger millet ( Eleusine coracana L.) seeds are found to be heavily infested with variety of fungi. These associated fungi are known to deteriorate the seeds and seed contents. Experiments were conducted to assess the effect of some dominant seed borne fungi of finger millet on seed germination and seedling vigour. Seven dominant fungi were found associated with finger millet seeds. Analysis of seed borne fungi by standard blotter paper method and agar plate method showed that species of Alternaria, Fusarium, Curvularia and Aspergillus are the dominant genera. Maximum reduction in seed germination and seedling vigour was caused by species of Aspergillus in seed inoculation and culture filtrate method. Thus, the associated fungal pathogens with finger millet seeds demonstrates that the seeds are a major source of transmissions of pathogens, which might have adverse effect at seedling and adult stage of plants.
