The traditional agriculture land use system in Indian Himalayan region is an integral part of the society and local environment as in that the crop husbandry, animal husbandry and forests constitute interlinked systems. But due to variety of factors the land use under traditional crops is changing very fast in a part of Indian Himalayan region. This kind of land intensification is a severe thre...

This paper describes the 'push-pull' or 'stimulo-deterrent diversionary' strategy in relation to current and potential examples from our own experiences. The push-pull effect is established by exploiting semiochemicals to repel insect pests from the crop ('push') and to attract them into trap crops ('pull'). The systems exemplified here have been developed for subsistence farming in Africa and ...

This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. The authors suggest agronomic practices, including tillage practices, rotations, and input management options that can ameliorate important constraints and sustainably improv...

since time immemorial, iranian women have played a pivotal role in agriculture, the largest industry contributing to rural livelihoods. hence, the present study was conducted in tafresh area of iran to examine factors influencing participation of rural women in mixed farming activities in 1999.this was a descriptive- correlation research project in which a total number of 300 rural women were s...

Andean tuber crop species oca (Oxalis tuberosa Molina), ulluco (Ullucus tuberosus Caldas), and mashua (Tropaeolum tuberosum Ruiz & Pav.) play major roles in Andean communities. These species show high variability but are threatened with genetic erosion. To study the management of genetic resources of neglected vegetatively propagated crop species, we studied genetic diversity and structure of t...
