Multistage random sampling technique was used to select the samples. The sample comprised 180 farmers. The crop-dairy enterprise mix was found to increase the returns on all size of farms. The higher incomes were obtained from dairy with higher employment. Dairy farming is one of the enterprises under prevailing conditions, which is successfully and profitably complimentary to the crop enterprises.

The machine consisted of an inclined chute, a series of rollers and a blower fitted on a rigid frame. The upper roller, which has 12 MS flats around the periphery of the rings, was covered with spongy rubber and ...

If the trend persists in similar manner, the temperature would rise above 3°C in another 20 years. The rise in temperature will have a profound effect on crop water demand and ultimately water resources. Crop water demand was determined under different temperature scenario with the help of FAO CROPWAT model, window version 4.2 (FAO, 1995) assuming other meteorological parameters as normal. The investigation revealed that with an increase in annual mean temperature by 0.5°C, the crop water demand increases by 1.1% and it may go as high as 7.8% if the temperature rose by 3°C.

A significant (p<0.01) decrease in draft and specific resistance were observed for oblique shank arrangement compared with parallel shank arrangement. Furthermore, the draft and disturbed area increased significantly (p<0.01) with increasing operating depth, whereas specific resistance decreased significantly (p<0.01) with depth for the oblique and parallel shanks arrangement respectively. The values of draft, disturbed area and specific resistance of the oblique and parallel shanks arrangement tested were affected significantly (p<0.01) by adding wings to subsoiler feet. Forward speeds had a significant (p<0.01) effect on studded parameters. The optimal performance were found with the forward speed of 0.341 m sec-1 .

Okra (Abelmoschus esculentus), Onion (Allium cepa L.) and Brinjal (Solanum melongena L.) are the three major vegetable crops grown in the district. Farm Science Centre known as Krishi Vigyan Kendra laid down front line demonstrations on these three vegetable crops under NAIP project by introducing improved and hybrid varieties and applying scientific package of practices in their cultivation. The productivity and economic returns of okra, onion and brinjal in improved technologies were calculated and compared with the corresponding farmer's practices (local checks). All the three vegetable crops recorded higher gross returns, net return and benefit cost ratio in improved technologies as compared to the plots where farmers were using traditional practices in their cultivation. It is suggested that location-specific integrated approaches would be needed to bridge the produ...

Organoleptic evaluation of dried slices, browning index indicative of color and the rehydration quality was used to establish safe ...

Different approaches namely National Agricultural Research System (NARS), Agriculture Knowledge and Information System (AKIS), farmer first and last, Participatory Rural Appraisal (PRA) and Public Private Partnerships (PPP) are/have come up to mitigate rapid changes over the years. The present agricultural research efforts are failing to bring about the social and economic transformations due to one or the other reasons. To cope, compete and survive in emerging challenges, it becomes necessary to develop new approaches. In this context, the concept of Agriculture Innovation System (AIS) approach offers a new framework for analyzing the role of science and technology and their interaction with other actors to generate goods and services. It recognizes the importance of certain types of relationships and linkages for information flow in ever-changing biophysical and social environments....
