The tree branches are shaken to speed up the harvesting, which results in post harvest losses due to the physical damage, stem end rot and sap bleeding in mangoes due to absence of pedicel. To overcome these local harvesting methods and to reduce the drudgery of the farmers Bihar Agricultural University, Sabour has developed five types of mango harvesters (Model A,B,C,D and E). Three harvesters (Model C,D and E) are manual operated and works on the principal of pulling/cutting, while one is power operated (Model B) which works on battery for power, and uses cutting principal, and another one (Model A) is manual-cum-power (battery) operated which uses cutting as well as pulling action for detachment of mangoes from tree branches. The local harvester harvests fruit without pedicel, whereas developed models, an improvement on the conventional harvester harvests the fruit with pedicel. The fruit harvest per hour was more in Model C (manual operated) that was (80-88 fruits/ 10 min) when compared to local harvester, manual plucking and tree shaking The number of labours per day for fruit harvesting was more in manual plucking and tree shaking, where as in developed harvester (Model C) took less labours that is (18 labours/day). Among harvesters Model C has higher efficiency over local model in labour and time saving. Model C has advantages over all the models A, B, D and E in terms of number of mangoes plucked, damages, and labour requirement.

Drying of paddy occurred in falling rate period. It was observed that duration of drying of paddy from 14.5 to 8 % moisture content (w.b.) was 4–6 h depending upon the source of energy used. In order to select a suitable drying curve five drying models (Exponential, Henderson and Pabis, Page, Logarithmic and Power law) were fitted to the experimental moisture ratio data. Among the mathematical models investigated, Page model best described the drying behaviour of paddy with highest coefficient of determination (r 2 ) values and least chi-square, χ 2 , mean bias error (MBE) and root mean square error (RMSE) values. Among all the drying models, Page model adequately described the drying behaviour of paddy using electrical heating source.

A higher rate of heat transfer can increase the production rate and may improve the quality of processed foods. In freezing processes, a faster freezing rate ensures the safety of the product against microbial growth and contamination. The convective heat flow is enhanced as the fluid motion increases. Air blast cooling processes are majorly ruled by the convective heat transfer, which relates the amount of transferred energy from the product surface to the cooling air. Wide variations in convective heat transfer coefficients may occur in different positions. This work reviews the effect of air flow and product arrangement on food freezing process because of their effect on the convective heat transfer coefficient.

It was observed that drying of cereal and pulses crops in STR dryer can remove the moisture up to 2-4 % in 6 to 8 hours of operation with quality retention of food material. The super grain bags were also tested which could arrest the moisture transmission up to some extent which helps in restoring the highest germination rate with better milling quality of paddy. The ample moisture migration and slight variation in lightness in super grain bags could retain the paddy quality than the other packing materials. It was found that farmer ‘awareness on post-harvest technologies is increasing, especially on dryer and super grain bags. The study concludes that PHTs have received high acceptance by farmers who have awareness and knowledge. However, th...

Greenhouse technology, a branch of controlled environment agriculture, has experienced fast growth, mainly due to climate change and the demand of high quality fresh fruit, vegetables, herbs and flowers in developed countries. Greenhouse Technology is the technique of providing favourable environment condition to the plants. It is rather used to protect the plants from the adverse climatic conditions such as wind, cold, precepitation, excessive radiation, extreme temperature, insects and diseases. It is also of vital importance to create an ideal micro climate around the plants. Greenhouses are framed or inflated structures covered with transparent or translucent material large enough to grow crops under partial or fully controlled environmental conditions to get optimum growth and productivity.This Book will serve for Agriculture Students undergoing undergraduate courses in India.

With the technological advancement in all spheres, agriculture has also witnessed developments with the introduction of robotics and automation. Agricultural robot or "Agribot" is a robot used for agricultural purposes. The advent of robots in agriculture drastically increased the productivity and output of agriculture in several countries. Further, the usage of robots in agriculture reduced the operating costs and lead time of agriculture. The current paper reviews the various applications of robotic agriculture in different areas of agriculture. The work also throws light on the future scope of robotic agriculture.

In order for freezing operations to be cost-effective, it is necessary to optimally design the refrigeration equipment. This requires estimation of the freezing times of foods. Estimation of food freezing time analytically is not possible, and numerous semi analytical methods for predicting food freezing times are available. A new method has been proposed for the prediction of freezing time and the performance of these various methods is evaluated in this paper by comparing their results to experimental freezing time data obtained from the literature. The proposed method shows error ranges upto 10 %, hence may be used for estimation of food freezing time.

It was observed that drying of cereal and pulses crops in STR dryer can remove the moisture up to 2-4 % in 6 to 8 hours of operation with quality retention of food material. The super grain bags were also tested which could arrest the moisture transmission up to some extent which helps in restoring the highest germination rate with better milling quality of paddy. The ample moisture migration and slight variation in lightness in super grain bags could retain the paddy quality than the other packing materials. It was found that farmer ‘awareness on post-harvest technologies is increasing, especially on dryer and super grain bags. The study concludes that PHTs have received high acceptance by farmers who have awareness and knowledge. However, th...

Greenhouse technology, a branch of controlled environment agriculture, has experienced fast growth, mainly due to climate change and the demand of high quality fresh fruit, vegetables, herbs and flowers in developed countries. Greenhouse Technology is the technique of providing favourable environment condition to the plants. It is rather used to protect the plants from the adverse climatic conditions such as wind, cold, precepitation, excessive radiation, extreme temperature, insects and diseases. It is also of vital importance to create an ideal micro climate around the plants. Greenhouses are framed or inflated structures covered with transparent or translucent material large enough to grow crops under partial or fully controlled environmental conditions to get optimum growth and productivity.This Book will serve for Agriculture Students undergoing undergraduate courses in India.

In order for freezing operations to be cost-effective, it is necessary to optimally design the refrigeration equipment. This requires estimation of the freezing times of foods. Estimation of food freezing time analytically is not possible, and numerous semi analytical methods for predicting food freezing times are available. A new method has been proposed for the prediction of freezing time and the performance of these various methods is evaluated in this paper by comparing their results to experimental freezing time data obtained from the literature. The proposed method shows error ranges upto 10 %, hence may be used for estimation of food freezing time.
