Contributions of Agricultural Research

Agricultural research, over the last five decades has contributed significantly to higher productivity and expansion of area under cultivation.

Impact of Agricultural Research

Agricultural research in India has been thus far the domain of the public sector. The large number of improved technologies developed have contributed significantly to higher growth in the agricultural and non-agricultural sector. Report of workshop of impact of research investment in agriculture.

Sustainability of Rice-Wheat Based Cropping Systems in India-Socio-Economic and Policy Issues

Systems in India Socio-Economic and Policy Issues Introduction RICE-WHEAT Cropping Systems (RWCS) gained prominence from the mid- 1960s with the introduction of short- duration and high-yielding varieties of rice and wheat during mid1960s. The rotation has spread in the most fertile regions and has covered about 10 million ha in the Indo-Gangetic plains (IGP) region of India. It is more popular in the non- traditional rice growing states of Punjab, Haryana and Uttar Pradesh, and less in traditional rice growing states of Bihar and West Bengal. The impressive performance of the system during the last three decades resulted in a quantum jump in the production of rice and wheal, which largely contributed in achieving the food self-sufficiency in India, The foodgrain production increased from about 90 million tonnes in 1964-65 to about 190 million tonnes in 1994-95, at an annual growth of little over 2.5 per cent.

Sustainability Implications of Burning Rice-and Wheat-Straw in Punjab

Rice-and Wheat-Straw in Punjab INTRODUCTION RICE and wheat have become the most prominent crops in the present Punjab since the mid 1960s. The total area under rice increased from 0.24 million ha in and covered approximately 54 per cent

Farmers Perception of Land Degradation-A Case Study

A Case Study P K Joshi S P Wani V K Chopde J Foster Top soil erosion is a serious problem threatening the sustainability of rainfed agriculture in the semi-arid tropics. Yet, farmers do not take strong measures to prevent soil loss. This study, covering farmers in a watershed in Yavatmal district of Maharashtra, attempts to assess farmers' perception of land degradation and examine their actions to alleviate its perceived effects.

Problems and Prospects of Co-Operatives in Managing Degraded Lands-Case of Saline and Water-Logged Soils

The article identifies problems and prospects of community approach in the form of co-operatives in curing or preventing saline and water-logged soils in Haryana and Gujarat. The technology of subsurface drainage as a measure to control salinity and water-logging is technically and financially feasible. In the absence of an appropriate organisational set-up, the technology could not be widely adopted because its viability would be questionable. The management of saline and water-logged soils needs a community approach and collective vigilance. In this context, co-operatives may play a significant role. However, several factors will determine the success of drainage coroperatives. These are: (i) the problem of free-riders, (ii) disparity in benefits from drainage, (iii) varia- lion in assets, caste and religion of members, (iv) participation of beneficiaries, (v) conflicting objectives between headand tail-enders, and (vi) perception of the programme objectives. The participation score in managing saline and water-logged soils was found higher amongst poor farmers. Differential persuasion and education strategies may bring about the necessary participation to facilitate managing problem soils through co-operatives.

Variability of Yields in Foodgrains Production since Mid-Sixties

The coefficient of variation of the yields of principal crops reveals a contrast between wheat and the other crops. For wheat, unlike [or rice, etc, deviations of state yields around national average nor- rowed over the years. Also intrastate, or inter-district, variations in yield narrowed in much the same way as inter-state variations.
