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.

The analysis of trends, seasonal variations and in market prices of rice in Guntur district and Andhra Pradesh and forecast the same for the period 1990-91 to 2009-10 collected from various published statistical bulletins. The seasonal variations in market prices and 12 months moving average method was used to construct the seasonal indices and Box-Jenkins model was used to forecast the future prices. The annual average wholesale price trends of rice from 1990-91 to 2009-10 has shown a significant increase over the years in both Andhra Pradesh and Guntur market.

Cancer is a major public health problem in both developed and developing countries. Plant derived products are being used for the treatment of cancer. Aromatic plants of lamiaceae family are known for its traditional medicinal value. The leaves of the plants are promoted in relieving cold, coughs, laryngitis, bronchitis, nasal congestion, inflammation of the mouth and throat. The leaves of Coleus amboinicus (C.amboinicus) have antioxidant, antibacterial, antimutagenic and anticancer activity. Ethanolic extract of C.

The pigweed beetle Hypolixus haerens Boheman has been cited as a major insect pest of grain amaranth worldwide. A study to evaluate injury level of both foliar and stem damage pests in Kenya revealed that the stem beetle H. haerens caused higher stem damage in the hotter zone (26-30 ºC) than the cooler zone (22-26 ºC) in the low midlands zones of Kenya.

The study measured the change and growth rate in area, production, and yield of wheat in Ethiopia based on secondary data during 1991/92-2012/13. Pared t-test was used to identify the significant change in area, production and yield of wheat between the periods 1991/92-2001/02 and 2002/03-2012/13. And semi-log model was applied to measure the compound annual growth rate of wheat for period I (1991/92 to 2001/02), period II (2002/03 to 2012/13) and the whole period (1991/92 to 2012/13).
