Groundwater table is declining in the state of Punjab over the decade more than 50 cm per year. This resource can be optimally used and sustained only when quantity of water is assessed at micro level.

An attempt was made to investigate the influence of different doses of nitrogen on growth and yield of pearlmillet under irrigated and non-irrigated in semi-arid region of Delhi with an aim to determine the optimum levels of N under two different moisture situations (irrigated and non-irrigated).

Soil-water is present in soil as film on the soil particles and in capillary form in soil pores. Soil water which moves slowly possesses potential energy which is due to position or internal condition. Soil water potential is influenced by different force fields: matric, osmotic, gravitational and pressure.

Field experiments on rice-wheat cropping were conducted in well-drained sandy loam soil of semi-arid region, Project Directorate for Cropping Systems Research, Modipuram, Meerut (UP) with the objectives to study the influence of tillage systems and irrigation schedules on soil cracking pattern, water requirement and performance of rice and wheat and rice-wheat sequence.

Hydrological risks to agriculture are mainly due to inadequate or erratic rainfall resulting in deficit water stress to crop plants. The susceptibility of agriculture production system to such risks can be assessed from the characteristics of rainfall, soil and plant.

In this paper a new dimension has been added to watershed management by proposing a whole programme by reorienting Bioindustrial Watershed Management. Land holdings are small, and are getting smaller. Even after all the available agricultural production technology, the small land holder's income are still remain small.

An investigation was conducted to evaluate the changes in soil quality over time under different systems of nutrient application in the erosion prone soils of rainfed areas of kandi belt of Jammu. The soils had been under three nutrient management systems, viz., nutrient application through inorganic, organic and integrated (organic+inorganic) sources for the last eight years.

The shifting cultivation in Nagaland state is described as an agricultural system where a farming community slashes secondary forests on a predetermined location, burns the slash and cultivates the land for a limited number of years. The land is then left fallow and the farming community moves to the next location to repeat the process till they return back to the starting point.

Soil infiltration and resistance to flow offered by soil and crop has a major influence on the entry of water below the soil surface in border-check irrigation. They are the key factors affecting the design of border-checks and need to be determined accurately. However, they change over the course of time, space and growing season, influencing the desing of border-checks.

Rice-wheat cropping system is most popular among the farmers in eastern Indo-Gangetic plains of India. The adoption of reduced and zero tillage seed drill of rice and wheat can improve the timeliness of sowing and help farmers.
