As in other parts of the world, the indigenous people of Jharkhand hold important context-relevant knowledge and strategies for addressing dwindling natural resources base and climate change. The paper documents some of the collective wealth of indigenous knowledge related to agricultural practices, including land preparation/ manuring/ soil treatment, cropping systems, input management, water resource management and utilization, and soil and water conservation practices, used especially by tribal farmers of the region. Related research and policy issues essential for successful amalgamation of such indigenous knowledge in resource conservation and climate change adaptation are also discussed. It concludes that the indigenous knowledge will help to address food and nutritional security in the face of climate change.

We assessed the cyanobacterial inoculation, green manure (GM) application, and chemical nitrogen (N) fertilization on grain/straw yield, nutrient balance, and nitrogenase activity under individual and integrated nutrient management mode in a rice-wheat cropping sequence. Individual and integrated application of cyanobacterial biofertilizer (CB) and GM with chemical fertilizer improved the soil health and production of rice crop. Integration of cyanobacterial and green manure resulted in a savings of 50 kg N ha-1. Functional relationships (R2, -83.5 to 95.7%) between the different sources of nutrients revealed that the maximum positive contribution of cyanobacteria was on final available N (45.2%) and available phosphorus (P, 18.5%). Green manure had the greatest contribution to total N, total P, zinc, iron, and manganese (Mn). However, cyanobacteria had a negative relationship with Mn and sodium (Na, -30.19%). A negative relationship with Na indicates the possibility of using cyanobacteria as an ameliorating agent for salt-affected soil. © 2013 Copyright Taylor and Francis Group, LLC.

The natural resources of most developing countries are under increasing stress, and many nations are increasingly concerned about achieving environmental sustainability through efficient use of land and water resources. As population is escalating very fast and consumer demand for high value agricultural products (fruits and vegetables, animal or fish products, etc.) is also changing rapidly. Hence, need to take stronger step by national governments to monitor their natural resources and take immediate steps to maintain these resources when being overused. Data generation by visiting the place physically is tedious and time consuming. Modern ICT techniques provide solutions helpful in collecting data without visiting the place from distance. With development of modern technologies, ICTs are of immense use in Sustainable Natural Resource Management. These technologies are time and money saving, accurate compared to conventional assessment. Products of these technologies help the scientists and policy makers for taking appropriate decision in agriculture production. It is thus important to recognize that the dissemination of these land and water-use management practices are largely knowledge-based; therefore, developing countries will be required to make substantial investment in public extension to train small and medium-scale farmers how to use Sustainable Natural Resource Management (SNRM) practices.

To know the extent and pattern of response by faba bean (Vicia faba L.) to alterations, a two year field experimentation was carried out with two crop establishment methods (i) flatbed planting, and (ii) raised bed planting; four planting geometries (i) 30 x 20 cm (ii) 30 x 30 cm (iii) 30 x 45 cm, and (iv) 45 x 45 cm; and three seeding depths in factorial experiment in complete randomized block design with three replications. Germination was significantly higher under raised bed planting (85.7 per cent) over flatbed planting. Early onset of flowering (58.3 days) and early maturity (97.5 days) was noticed in shallow depth (5.0 cm) of sowing. Maximum plant height (86.8 cm) was noted under raised bed planting. Maximum leaf area index (LAI) was recorded (4.15) with planting geometry (30 x 30 cm) at 90 DAS. Leaf weight ratio (LWR) and RGR were influenced with all the treatments. Pods per plant, seed yield (g/plant and kg ha-1) were influenced significantly with all the treatments. Raised bed planting proves superior over flatbed in case of seed yield. Square planting with 30 cm planting distance proved better (3,690.9 kg ha-1) than other planting geometries. Seeding at 10 cm depth showed significant improvement in seed yield over other two tested seeding depths.

Pressurized irrigation technologies of course have the potential to raise the productivity of land and water; but, these technologies could not popularize among the smallholders who own millions of farms worldwide. In developing pressurized irrigation technologies, particularly for field crops irrigation, researchers and manufacturers have developed more specialized and expensive technologies with sophisticated and intricate hardware. These new technologies have benefited only the large and wealthier farmers leaving the smallholders to remain confined with conventional methods of irrigation. This paper discusses the design, performance, and applicability of a low-pressure water sprinkling nozzle, named LERN. This nozzle can be operated satisfactorily over the operating pressure range of 79-117 kPa. The water application rate of LERN is reasonably high, i.e. 20-23 mm h-1; therefore, field crops such as rice, wheat, oil seed etc. can be irrigated quickly and efficiently even at small plots, where available options such as impact sprinklers are, in general, neither feasible nor applicable due to high pressure requirement (196 - 294 kPa), non-divisibility over small plots, and relatively high cost of pumping and system networking. Since the pressure requirement at the nozzle head reflects overall cost of a pressurised irrigation system, LERN holds greater promise in development of a cost effective pressurized irrigation system for irrigating field crop even at small plots. © 2015, Tarbiat Modares University.
