ABSTRACT
This chapter reveals that grain yield of Niger, black gram and mustard were 33.4%, 23.5% and 26.6% higher than the control, respectively. Kandhamal region of India receives rainfall around 1396 mm per year. Due to its uneven distribution, heavy downpour of rain at times results in sudden high runoff, which ultimately causes substantial soil loss. The uneven distribution of rainwater and movement of soil within the watershed results heavy loss to farmers. Therefore, conservation trenches for plantation crops help to conserve the soil and moisture and ultimately improves grain yield for the farmers. Kandhamal district situated in central part of Odisha receives an annual rainfall of 1396 mm and this region is highly prone to soil and runoff loss due to heavy rainfall during kharif. A trial was conducted during 2001-2004 to study the effects of conservation trenches on plantation crops.
