This study would like to point out the potential compounds as inflammatory agents. Herein, we displayed the isolation and structural identification of thirteen compounds including ten flavonoids, one tannin, one triterpenoid, and one derivative of benzoic acid from the methanolic extract. Furthermore, all of them were evaluated the anti-inflammatory activity.

Our previous study demonstrated that plant extract-based diets of E. hirta and P. guajava were effective to stimulate immune responses in striped catfish (P. hypophthalmus). Therefore, in this study, we investigated the chemical investigation as well as the immunomodulatory potential of some isolated compounds from E. hirta and P. guajava.

Abiotic factors viz., atmospheric temperature, relative humidity, sunshine hours, rainfall, soil temperature and moisture play a crucial role in the development and sustainability of the soil mesofauna population. An experiment was carried out in Guava (Psidium guajava L.) ecosystem from October, 2015 to September, 2016. Soil and litter samples were drawn and mesofauna were extracted at fortnightly interval.

Guava (Psidium guajava L.) is an important fruit crop of tropical and subtropical areas of the world. Genomics resources in guava are scanty. RNA-Seq based tissue specific expressed genomic information, de novo transcriptome assembly, functional annotation and differential expression among contrasting genotypes has a potential to set the stage for the functional genomics for traits of commerce like colored flesh and apple color peel.

The ripe fruit contain approximately 79.50 per cent moisture, 15.25 per cent dry matter, 3.20 per cent crude fibre and little amount of ash. The TSS varies from 10.5-14.5 per cent. Several volatile compounds including hydrocarbons, alcohol and carbonyls have been found to be responsible for the characteristic flavor of guava. The decrease in astringency with advancement of maturity is ascribed to polymerization of leuco-anthocyanins.

The results of the present investigation indicated that, different pruning treatments and fertilizer levels produced significant effect on growth and yield attributes of guava. The treatment of 45 cm of past season’s growth with application of fertilizer levels of 125% RDF (1000:500:500 g NPK/tree) recorded the significant effect on the growth parameter like plant height, shoot length, shoot diameter and number of leaves per shoot and produced maximum values of all these growth parameters with minimum days of flowering and fruit set. The maximum yield (60.41 kg/tree and 16.79 t/ha.

The study revealed that the guava + banana and guava + eggplant systems were proved to be the most significant intercropping system by improving physio-chemical properties like bulk density, water holding capacity, SOC, available NPK of the soil. The maximum system equivalent yield and economic return were obtained from the same system. Thus the guava + banana intercropping system is not only the best for restoring soil fertility but also obtaining the maximum economic return for guava growers of West Bengal.

An experiment was conducted onwedge grafting time, growing conditions on subsequent growth of grafted plants in guava (Psidium guajava L.) during 2014-2015.Wedge grafting was done during August (M1), September (M2), October (M3), November (M4), December (M5), January (M6) and February (M7)months under poly house and 50% shade net conditions. Wedge grafting in the month of August under poly house condition gave better response with respect to number of leaves per sprout, leaf area per sprout and leaf chlorophyll content.

Guava (Psidium guajava L.) is an important fruit crop and good source of income for Indian farmers. It’s infested with some major pests including plant parasitic nematodes. The number of plant parasitic nematode species associated with guava but some species are cause great losses. The accurate identification of nematode species is a basic key of successful management. Soil and plant samples collected from fields of guava from Arathwara village, Sheoganjtehsil, Sirohi district of Rajasthan, India on the GPS location 250 03’40.7”N; 720 58’05.0”E.
