The study was carried out during 2017–18 at farmers’ field in three villages (Lohani, Bhatkar and Pundrenka) under Chamba district of Himachal Pradesh, India. Front line demonstration of gobhi sarson (Brassica napus) was conducted on an area of 10 ha with active participation of 64 farmers with high yielding improved technologies composed of HPN3 variety, integrated pest management (IPM) and integrated nutrient management (INM). The results revealed the increase in average yield under front line demonstrations by 2.16% as compared to the farmer’s practice. Improved technology gave higher net return of Rs. 10908 -ha-1 with benefit cost ratio 0.49 as compared to local check (INR 7600 ha-1, benefit cost ratio 0.44).

Introduction
Gobhi sarson (Brassica napus) is a new emerging oilseed crop having limited area of cultivation. Gobhi sarson is a long durationcrop (more than 155 days) confined to Punjab, Himachal Pradesh and Haryana (Kumar et al., 2009). Among the rabi oilseed crops, gobhi sarson (Brassica napus L.) is a high yielding oilseed crop suitable for high fertile soils under assured irrigation conditions. Moreover, it contains higher oil content (41–45%) of good quality having high recovery of essential fatty acids i.e. oleic, linoleic and linolenic acid. B. napus is a hybrid evolved from B. rapa (syn. B. campestris) and B. oleracea (wild mustard) through crossbreeding (OECD, 1997). All parts of the rapeseed plant are utilized: seeds are used for the production of oil for human nutrition, or for biodiesel; leaves are consumed as vegetables (mainly in Asia) and as animal fodder; oilseed cake and rapeseed meal (after hexane extraction), being by-products of oil processing, are used as protein-rich animal feed; dried stalks are used as domestic fuel. B. napus or rapeseed is mainly cultivated because its seeds yield about 40% oil. Oil content (%) was determined by taking a sample of seeds of each plot of all the replications following the standard method (AOAC, 1960).
India is the third largest rapeseed oil producer in the world after China and Canada with 12% of world’s total production. This crop accounts for nearly a third of the oil produced in India, making it the country’s key edible oil-seed crop. Due to the gap between domestic availability and actual consumption of edible oil, India has to resort to import of edible oil with a projected demand for edible oil at more than 20 million tonnes in 2014–15. Gobhi sarson is the predominant crop grown during rabi season after paddy or maize on rainfed farms of the study area. Gobhi sarson requires relatively cool temperature of below 25 °C and adequate supply of soil moisture during the growing season. It is also grown in certain tropical and sub tropical regions as a winter crop. Indian mustard is reported to grow well in areas having 250 to 400 mm of rainfall and has an efficient photosynthetic response at 15–20 °C temperature. Sowing time is the most vital non-monetary input to achieve target yields in mustard. Sowing time also influences phenological development of crop plants through temperature and heat units. Sowing at optimum time gives higher yields due to suitable environment that prevails at all the growth stages of the crop.
Lack of suitable high yielding varieties as well as poor knowledge about production practices are described as main reasons for low productivity of gobhi sarson in the district. The productivity of gobhi sarson could be increased by adopting recommended scientific and sustainable management practices using a suitable high yielding cultivar. In order to get optimum yield of this crop, selection of variety, seed rate and seed treatment are the most important factors to be followed by the farmers (Sharma et al., 2018). Taking into account above considerations, front line demonstrations (FLD) were carried out in a systematic manner on farmers’ field to show the worth of a new variety and convincing farmers to adopt improved production management for enhancing productivity of Gobhi sarson. Efforts are being made by the KVK to motivate the farmers to grow these crops by organizing awareness camp vis-a-vis training programmes and field days.
Materials and Methods
Front line demonstrations on gobhi sarson was conducted in 2017–18 in Chamba district of Himachal Pradesh, India. The demonstrations were laid out in 3 villages namely Lohani, Batkar and Pundrenka of Chamba district. The farmers were selected through proper survey of the area in both seasons as suggested by Choudhary (1999). Seed of variety HPN3 was distributed among the farmers and sowing was done by broadcasting method. A total area of 10 ha was put under FLD. Regular visits by the KVK scientists to demonstration fields were ensured and made to guide the farmers. The critical inputs were duly supplied to the farmers by the KVK. Group meetings were organized at the demonstration sites to provide the opportunities for other farmers to witness the benefits of demonstrated technologies. Yield data were collected from control (Farmer’s practice) and demonstration plots and cost of cultivation, gross income, net income and cost benefit ratio were computed and analyzed.
Results and Discussion
The data presented in Table 1 shows the comparison between the FLD and farmer’s practice and it was noticed that Gobhi sarson variety HPN3 was high yielding and was grown under the guidance of KVK scientist. Farmers were not using plant protection measures and integrated nutrient management practices which were demonstrated under FLD plot.
Nitrogen @120 kg ha-1 was applied and the dose was applied thrice. 60 kg ha-1 of nitrogen was applied at the time of sowing and 30 kg was applied 60 days after sowing and the rest dose was applied after 80-90 days of sowing. Phosphorous (60kg ha-1) and Potash (40kg ha-1) was applied at the time of sowing. Weeding was advocated as and when required.
The data presented in Table 2 revealed that the demonstrations on new technologies help the farmers in increasing the farm income.
The net returns under the FLD plots increased over the farmers practice. The average yield 5.7 q ha-1 was recorded under the improved practices whereas average yield of 4.0 q ha-1 was recorded under farmers practice. Although both the yields under improved practices and farmers practices are low as compared to the reported productivity of 15.0 q ha-1 (CSKHPKV, 2016.) due to drought conditions prevailed during the growing season. The B:C ratio was also higher under the demonstrated plot as compared to the Farmer’s practice. On an average, Gobhi sarson yield under front line demonstration was higher by 2.16% as compared to the farmer’s practice.The results indicated that the demonstration has given good impact in terms of yield and income. The higher productivity of Gobhi sarson under improved technologies was due to sowing of latest high yielding crop variety and adoption of improved nutrient and pest management techniques.
Conclusion
Front line demonstration is one of the most important tools of extension to demonstrate crop management practices at farmer’s field. By conducting FLDs, yield potential of oilseed crops can be increasedto a great extent. The production technology, including adopting high yielding varieties of Gobhisarson and fertilizer doses of NPK and FLDs are being adopted by the farmers to attain maximum benefits from their fields and KVKs are playing important popularising the improved practices through training programs and demonstration in the farmers filed.

Overview
The present book on Plant Anatomy depicts anatomical aspects of the plant that will help a reader for basic understanding in the evolution of different plant communities. It plays an important role for adaptation of plant to different biotic and abiotic stress. It has been documented that some glands, trichomes, epicuticular wax are resistant to insect pests. Similarly, the presence of trichomes epicuticular wax, compactly arranged palisade tissue, collenchyma and sclerenchyma induces drought resistance. So it is necessity of all scientists, especially for breeder, plant physiologist to have the thorough knowledge on plant anatomy for the selection of adaptable cultivars and also for better management of crops. This book covers all the aspects of internal structures of plant with its high resolution microscopic images and drawings of plant parts. The anatomical studies of plants organs are being presented here, as we believe that the morphological characters alone cannot project the adaptations in the plant. They can be better understood when supplemented with the anatomical characteristics, unique to individual type of crop. This text book would be of great help to faculties and scholars in plant as well as agricultural sciences and scientific communities in general as a good source of information and references
As per the Veterinary Council of India (VCI) syllabus, accounting is a part of BVSc & AH course in the discipline of extension education. However, there is a dearth of text book on this course written or verified by an expert in accounting.This book is expected to fill this gap. The book consists of seven chapters covering the VCI-syllabus on accounting with exercise, and summary at the end of each chapter. Besides, glossary and model questions covering all chapters with answers to the objective questions are appended to the end of the book. The book may not only benefit the students pursuing BVSc&AH degree but also the teachers engaged in the teaching of the course in veterinary colleges and universities in India. Besides, the farm businessmen and those interested in accounting may also find the book useful.

The present book, Botany of Vegetable Crops, is different from other books on vegetable crops. It contains 12 chapters with emphasis on major vegetable crops like Tomato, Chilli, Egg plant / Brinjal, Okra / Bhendi, Water melon, Bottle gourd, Bitter gourd, Cucumber, Ridge gourd, Sponge gourd, Cabbage and Coriander. It discusses on the morphology and anatomy of a few common vegetable plants. Morphological characters help in identifying the plant. It also gives an idea of the different adaptive modifications in the plant. It even mirrors the habitat, the climatic conditions under which it can be cultivated. The anatomical studies of each of the vegetable plant are also being presented here as we believe the morphological characters alone cannot project the adaptations in the plant. They can better be understood when supplemented with the anatomical characteristics unique to individual type of crop. Glossary added in this book can help readers to understand some related terminologies and bringing clarity of the content. We expect that this book would be of great help to a student of plant sciences, to a research scholar for reference and a good source of information, to a plant breeder, and to the scientific community in general.

Overview
The book is the compilation of comprehensive study of vegetable and tuber crops Worldwide. In the changing scenario of climate, it is well understood that merely agronomic management practices starting from sowing to nutrient, water, pest and disease management will not be able to produce potential harvest. In present days, growth limiting factors like drought, heat, cold shock, chilling stress, salinity, metal stress, allelopathy have posed alarming threat against successful crop production. So, physiological basis of crop growth and productivity must be well versed to formulate appropriate counter measures to overcome such constraints. Moreover, the productivity of the crop is guided by various physiological processes like efficient seedling growth, photosynthesis and translocation of photosynthates, sucrose accumulation, growth regulators, ABA, ethylene, brassinoid and balanced mineral nutrition etc. Authors have tried to concentrate all these aspects in lucid manner reviewing the up-to-date research investigation. The book widely covers solanaceous crops like chilli, potato, tomato and eggplant; cucurbit vegetables- squash, pumpkin, cucumber, bottle gourd, bitter gourd, muskmelon and watermelon; cole crops- spinach, coriander, parsley, celery, lettuce; root and tuber crops- carrot, turnip, beet root, radish, turmeric, colocasia, cassava, yam, sweet potato; bulb crops- onion, garlic, leeks; leguminous crops- cluster bean, snap bean, green peas, broad bean; other crops like okra, sparagus, shallot, rhubard. It will definitely be a rare book to the global readers.

The book Research Advances in Vegetable Crops is an outstanding contribution of the authors in the field of advancement of the vegetable researches all over the World. The book entitles from the seed germination and its necessity of establishment in the new environment where physiological responses are influenced by both biotic and abiotic factors. Priming is a simple technique that not only helps in proper germination but aid in seedling establishment. Phonotypical and physiological responses of different vegetable crops are of significant importance in relation to factors like nutrients, salinity, disease-pest attacks. Physiological and biochemical basis of tolerance to salinity is very important that may help in the evaluation and selection of pipeline hybrids and parents lines using a novel technique. Biotic factors are major constraints in crop production, so proper management strategies and control measures must be taken for potential outcome. In this book, a special emphasis was given on food value and food chemistry of different vegetable crops. Major aspects like nutritional value of fresh vegetable as well as food value, post-harvest physiology and processing, storage and food quality, medicinal values, food chemistry and food biotechnology have been discussed in lucid manner. Further, research advances in biotechnology of different crops will guide authors in formulating the direction of future research.
