The present study was undertaken in five years old mulberry germplasm maintained at Sericulture Department, University of Agricultural Sciences, GKVK, The study was conducted in all three seasons of the year viz., pre monsoon (March-June), monsoon (July-October) and post – monsoon (November – February). Two defoliators namely Bihar hairy caterpillar, Spilarctia obliqua Walker and Wingless grasshopper, Neorthacris acuticeps nilgriensis Uvarov were selected for the study.

The study measured the growth and instability in area, production, and yield of the vegetable crop tomato in Ethiopia based on secondary data during 1991/92-2013/14 using different statistical techniques. Compound growth rates of area, production and yield were estimated by fitting semi-log trend equation. The study analyzed that, a negative annual percentage change was experienced in yield and a positive annual percentage change was observed in area and production over the study period.

Eco-friendly production practices have recently embraced in various regions in Vietnam, particularly for horticultural produce, to meet the increasing demands by both domestic and overseas markets. The practices would not only bring about secure income for producers but also contribute to economic, environmental sustainability and improved human health in broad terms. Leafy radish is one of the important cash crops in the urban and outskirts of Thai Nguyen city (Northern Vietnam).

Jujube, Ziziphus mauritiana is one of the most ancient fruit crops of Sindh, Pakistan consumed for its nutritional and medicinal purpose. However, the occurrence of foliage insect pests especially jujube beetle (Adoretus pallens Har) is the major threat to reduce the quality and quantity of fruits, ultimately causing tremendous economic loss to the growers. Thus, the main focus of current study was to develop the Integrative Pest Management (IPM) approaches for jujube beetle.

Amrasca biguttula biguttula (Ishida) (Hemiptera: Cicadellidae) is cell sap sucking insect pest of Sunflower Helianthus anus (L.) which affect the yield of crop by allowing leaves yellow, curly, causing sooty moulds and affecting photosynthesis of the crop plant. Therefore, vertical destructive pattern of this species has been reported. The lower leaves had lowest number of nymphs and upper highest. The peak of incidence was noticed in the month of August and it was higher in low rainfall spots (Shirol and Kolhapur) than in higher rainfall spot (Radhanagari).

This study aimed to achieve typology of cattle production system related to social and structural characteristics. It was conducted in the two main breeding regions (central and northern) of Côte d’Ivoire; in 5 five departments of the central region and 7 departments in the northern region. A total of 1,041 farmers were interviewed; 599 farmers in the central region and 442 in the northern region. The results showed that cattle livestock production practices are closely linked to the social, lifestyle and skills of farmers.

Ib is an important river of Jashpur district (C.G.). Two sampling station viz., station 1 Dhondidand and station 2 Dhondibahar, were established for the collection of water samples during July 2012 to Oct 2012. Monitoring of water of river Ib includes physico-chemical parameters and analysis of iron and copper metal. The temperature was 18.20C to 24.60C, pH of river water ranges from 7.12 to 7.85, Turbidity ranging between 11 NTU to 14 NTU, Conductivity ranged from 50 μs/sec to 55 μs/sec, Alkalinity was 7mg/l to 11 mg/l. TDS ranged from 32 mg/l to 44mg/l.

Einstein, in the equations of the General Relativity, departs from three premises: 1/ Equivalence between inertia, gravity and mass. 2/ Distortion of the space for the mass, and equivalence between mass and spatial distortion. 3/ Equivalence between gravity and uniformly accelerated motion. From this viewpoint conceptual and pre-relativist is where I have something to add. I try to postulate the braking effect as equivalent to gravity. Then results it make more understandable the gravity, the inertia, the uniformly accelerated motion and also the mass.

Cardanol an agricultural byproduct of cashew industry with m-cresol in various molar concentrations were condensed with formaldehyde. The resins R1, R2 and R3 thus prepared and characterized. The spectral studies confirm that the ortho substitution is favoured when the concentration of m-cresol is more. Polyurethanes PUR1, PUR2 and PUR3 were prepared using this resins and hexamethylene diisocyanate, an aliphatic diisocyanate. The polyurethanes were characterized by thermal, mechanical and x-ray diffraction studies. The polyurethanes have good thermal stability.

Densities (ρ) and viscosities (η) have been measured at 308.15 K over the entire composition range of binary mixtures of Tetrahydrofuran (THF) with benzene (B), methyl benzene (MB), ethyl benzene (EB), chloro benzene (CB), bromo benzene (BB) and nitro benzene (NB). This measured data have been utilized to calculate excess molar volume (VE), excess viscosity (ηE) and excess gibbs free energy for activation of viscous flow (G*E) and Grunberg-Nissan interaction parameter (d1). The values of these excess functions are fitted to the Redlich Kister equation.
