Efficacy of Biocontrol Agents in Controlling Bacterial Wilt on Naga King Chilli (Capsicum chinense Jacq.)
Abstract
Available biocontrol agents were evaluated either alone or in various combinations for finding out their efficacy in suppressing bacterial wilt incidence and promoting plant growth of Naga king chilli (Capsicum chinense Jacq.) under field conditions. Among all tested combination, the treatment containing combination of T. viride +P. fluorescens was found most effective in reducing the incidence of bacterial wilt in field condition. Highest per plant yield was also recorded from the same combination and it was followed by T.viride. However, the commercially available fungicide Copper oxychloride (0.1%) showed the lowest (11.11%) disease incidence in field condition.

Morphometric studies on Indian honey bee, Apis cerana and little bee, Apis florea in Tamil Nadu
Abstract
The present investigation on morphometric variations in Apis cerana and A. florea was conducted in the Department of Agricultural Entomology, Killikulam, TNAU during 2012-13. Reddish honey bees are said to possess resistance to diseases. We screened the Indian bees, Apis cerana and the little bees, Apis florea available on the campus for any morphological colour variation besides hamuli number on the hind wings. They were examined for the colour variation in abdominal tergites and sternites and the thoracic scutellum. The number of hamuli present on the hind wing were also examined. The results indicated no significant variation in colour and hamuli. All bee colonies sampled in the campus were yellowish in colour, except for the black scutellum in A. florea. The number of hamuli averaged 18.0 in A. cerana and 11.0 in A. florea.

Popularization of Wheat Raj 4037 through FLDs in Baran District of Rajasthan
Abstract
Frontline demonstration (FLD) is one of the most important and powerful tools for transfer of technology. Keeping in view of an effective extension approach of FLDs for dissemination of technology FLDs on wheat were conducted by KVK, Anta-Baran, Rajasthan was assessed. The yield and economic performance of frontline demonstration, horizontal spread of technology, extent of adoption level and the extent of satisfaction level of respondent farmers over extension services and performance of demonstration was measured in this study. It was observed that there was 11.47 to 16.26 percent increase in grain yield over local check and the average benefit cost ratio was higher under demonstration as compared to control plots during the all years of the study. It was estimated that the horizontal spread of wheat Raj 4037 was from about 100 ha during 2008-09 to1.32 lac ha during the year 2014-15. The findings of the study also revealed that they had increase in adoption level ranging from 07.62 percent of storage to 33.33 percent of improved and quality seed after conducting the FLD programmes. The majority of the respondent farmers expressed medium (48.57%) to the high (36.19 %) level of satisfaction for extension services and performance of technology under demonstrations. It can be concluded that frontline demonstration conducted under the close supervision of scientists is one of the important tool for extension to demonstrate newly released crop production and protection technologies and its management practices in the farmer’s field under different agro-climatic regions and farming situations.

Land application of composted poultry litter as a nutrient source for the growth of Lycopersicum esculentum.
Abstract
From the statistics it was seen that India is expected to produce 260 million layers (77,700 million eggs) and 3500 million broilers (5.9 million tonnes) in the year 2010. Poultry development in the recent past has shown very fast development and at present in A.P. the total population of poultry is 193 millions and from these birds the litter is estimated at 17.70 lakh tons per year. This tremendous increase of poultry industry results in substantial amounts of poultry litter, which can efficiently use in solving the present agronomic problems thus leading to sustainable agriculture. The application of poultry litter on land has been a long used disposal method that benefits soil and plant. Composted poultry litter is being applied on agricultural fields as an amendment to provide nutrients and also enhance the organic matter content and improve the physico-chemical properties of the cultivated soils. In the present study, quantitative changes in physical, chemical and microbial properties of composted poultry litter were studied. In order to understand the composting process and evaluate the suitability of composted poultry litter as soil amendments to Lycopersicum esculentum plant, Lycopersicum sps was planted and monitored for growth performance and yield. The effect of land application of composted poultry litter on the soil organic matter content and other properties as the soil quality indices were being evaluated in this case study.

OMICS in Molecular Biology
Abstract
Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis, the transcription factor as well as learning how these interactions are regulated. The scientific world is not the same again, and neither can society as the impact of ‘omics’ spreads from the laboratory to everyday life. This review can give a brief idea on different Omics in Molecular biology and its applications.

Performance of chickpea (Cicer arietinum L.) under Planting techniques and irrigation levels
Abstract
Field experiment was conducted during two consecutive year of 2009-10 and 2010-11 at Agricultural Research Station, Navsari Agricultural University, Tanchha to find out the effect of planting techniques and irrigation levels on chickpea growth and yield. Total 12 treatment combinations including three irrigation levels as main plot treatment (viz., I1: One irrigation at branching stage, I2: One irrigation at pod development stage and I3: Two irrigations at branching and pod development stages) and four Planting pattern as sub plot treatment (viz., P1: Flat bed sowing, P2: Furrow after two rows, P3: Furrow after three rows and P4: Furrow after four rows) with one control were evaluated in split plot design. Significantly higher grain (1122, 1152 and 1137 kg/ha, respectively) and stover (1960, 1838 and 1899 kg/ha, respectively) yields were recorded under application of two irrigation at branching and pod development stages and remained in the I3 > I2 > I1 order of significance. Various planting techniques significantly improved the grain and stover yields of chickpea being maximum grain (1109, 1140 and 1125 kg/ha, respectively) and stover (1958, 1830 and 1894 kg/ha, respectively) yields were obtained under treatment furrow after four rows method of sowing. Higher and profitable yield of green gram was obtained under furrow after four rows pattern of sowing and applied two irrigation at branching and pod development stage.

Nutritive value of some selected indigenous livestock browse species in the drylands of Southern Province, Zambia
Abstract
Indigenous browse is an important source of quality nutrition of grazing animals in the dry season in arid and semi-arid regions. This study investigated the nutritive values of four important browse species in dry region of southern Zambia. Samples of fresh leaves were collected during the dry season (September to November). The frequency and the density of the browse trees in the grazing area was measured. Crude protein were similar for Julbernadia globiflora and Brachystegia spiciformis (11.70±0.14 and 11.42±0.31 respectively) but were higher than for Dichrostachys cinerea and Piliostigma thonningii (p<0.05). Crude fibre was found to be lowest in Dichrostachys cinerea with 18.16±0.16% which also contained the highest amount of tannins with 4.10±0.06% (p<0.05). Piliostigma thonningii had the highest levels of calcium of 1.76±0.03% and Dichrostachys cinerea had the least amount with 1.35±0.18% (p<0.05).The leaves of Brachystegia spiciformis had the highest digestibility of 67.95±0.85%, followed by Dichrostachys cinerea with 66.03±1.95%, Julbernadia globiflora with 49.47±1.06%, and Piliostigma thonningii with 24.82±2.62% (p<0.05). Overall, the browse species assessed are abundant and have a good potential to supply nutritious and fairly digestible feeds suitable for ruminant feeding in the dry season.
