A field trial was conducted during two consecutive summer seasons of2012 and 2013 at ICAR-Central Potato Research Station, Shillong, Meghalaya to evaluate the integration of nutrient sources on productivity and soil health under rainfed potato cultivation in north eastern hill region of India. There were six treatments of integrated nutrient management viz., 100% Recommended dose of fertilizers,75% RDF through synthetic fertilizers and 25% recommended dose of nitrogen (RDN) through FYM, 50% RDF and 50% RDN through FYM, 25% RDF and 75% RDN through FYM, 100% RDN through FYM and control (no application of any sources of nutrients). The experiment was laid out in randomized block design with four replications. Nutrient management practices showed the significant improvement on growth and yield attributes of potato over control plot. Highest productivity of potato tubers (t/ha) was noticed with application of 75% RDF through synthetic fertilizers along with 25% RDN through FYM. Similarly, the maximum net return was associated with application of 75% RDF and 25% RDN through FYM under investigation. Application of 75% Recommended dose of nutrients through synthetic fertilizers in combination with 25% Recommended dose of nitrogen through FYM was more profitable for sustainable production of potato in the north eastern hill region of India.

Abstract Climate change (CC) is real and threatens the livelihood of most smallholder farmers who reside along the coastal area. The CC causes the rise of temperature (0.2-0.3°C/decade) and sea level (SRL = 5 mm/year), drought and floods to occur more frequently, the change of rainfall intensity and pattern and shifting of planting season and leads to the decreasing of crop yield or yield loss. Most of the paddy soil has been exhausted and degraded. About 50% of the rice field along the coastline is effected by high salinity and causes significant yield losses. The research was aimed to summarize the results of the system of organic based aerobic rice intensification (known as IPATBO) and of two climate filed school (CFS) in Cinganjeng and Rawapu that situated along the coastline of Pangandaran and Cilacap. Both IPATBO and CFS have adopted the strategy of climate-resilient sustainable agriculture (CRSA) for restoring the soil health and increasing rice productivity, and as well as to empower the farmer community. The implementation of IPATBO (2010-2020) in the different areas has increased the soil health, fertilizers, and water efficiency (reduce inorganic by 25-50%, and water by 30-40%) and increased rice productivity by at least 25-50%. Both CFS in Ciganjeng and Rawaapu were able to improve soil fertility, increase rice productivity, and farmer capacity. This result concludes the agro-ecological based CRSA and CFS can be adopted for the increasing the resilient of agricultural practices and farmers in adapting to climate change

The climate of the terai region of West Bengal, India in general, is subtropical par humid to tropical with light textured acid soil with the problems like low moisture retention, low water use efficiency, leaching of bases, soil erosion, limited availability of multiple plant nutrients and restricted activity of beneficial soil micro-organisms. To combat these soil health related problems and to improve the overall productivity of North Bengal, a comparison between the conventional and conservation tillage was taken up and the immediate results were measured in terms of growth, yield attributes and yield. In the first two years of experimentation, though different growth attributes, grain yield, stover yield, and different yield attributing characters such as kernel rows cob-1, number of kernels row-1, 100 seed weight (g), number of seeds cob-1, girth of cob, length of cob and number of effective cob plant-1 were higher in conventional tillage as compared to conservation tillage but in terms of soil heath characteristics, conservation tillage had a meaningful remark from the initial years towards the future food security. Mulching @ 4 t ha-1 was found to have performed better than unmulched treatments. Application of 75% recommended dose of fertilizer + Vermicompost @ 10 t ha-1 resulted in better growth and yield attributes which directly influenced to have higher grain and stover yield.
