Evaluating the impact of contingent crop (Niger) on rice fellow upland under rainfed ecosystem of Koderma district of Jharkhand

Abstract

The evaluation of contingent crop (Niger) has been placed in two different locality of Koderma (Jharkhand). The two locations for inception of trail were selected on the basis of failure of primary Kharif season crop rice on upland field condition. Aberrant and harsh weather condition including erratic, sometime lack to rainfall forced the farmers to transplant aged seeding which may directly affect the yield of rice. In the year of 2016-17 the Basdih and Padriya village of Markacho block were selected for placement of Niger crop. The annual rainfall of Koderma region has been depicted by 200-250 mm, because of unavailability of irrigation water total 35 hectare (Basdih village 20 hectare and Padariya 15 hectare) of rice cultivated land have been failed to grow. So short duration, drought tolerant variety of Niger (JNC-6) has been sown. After collection of field data the results shows that the yield of niger on upland area recorded 3.5 quintal per hectare (net worth income 22, 072 INR), besides the yield on medium land observed up to 4.6 quintal per hectare (net worth income 22, 934 INR). This study shows land uses change in failure of primary crop with the application of contingent crop, the focus of study was based on aware the farmers about continuous change in environmental condition and selection of technology, varieties and showing methodology according to current climatic scenario.
