Summary
This experiment began in 1967 at a site that was originally
shrubland. The project consists of one rotation: Pearl
millet-wheat. Treatments = 1) Absolute control, 2) Farm yard manure
added, 3) N-fertilizer applied, 4) Cultivation without pesticides, 5)
Incorporation of root stubble.

The climatic region of the site is Warm Temperate SubTropical. The
... average climatic conditions at the experimental site

Minimum annual temperature: 16.1 deg C
Mean annual temperature: 23.8 deg C
Maximum annual temperature: 31.5 deg C
Minimum annual rainfall: 139.4 mm
Mean annual rainfall: 426 mm
Maximum annual rainfall: 796.8 mm

The soil is described as a Fine loamy aridic ustochrept (USDA).

The measurements made, methodology, and frequency are listed below:

a) Vegetation measurements made and frequency

Total above-ground dry matter: Every season
Nitrogen content of offtake: Every 2 years.
Phosphorus and potassium offtake in above-ground dry matter every 2
years.

b) Soil sampling

Time zero soil measurements taken. Samlping depth: 0-15cm, samples
not stored, measurements taken: pH, organic C, CaCO3, Available N, P and K.
Details of soil sampling method: Method of soil sampling: Auger.
Number of cores: 4. Area of plot sampled: Borders of plots not
sampled. Distribution of samples: Random. Soil is separated into layers
Details of measuring depths and soil layers: Depthwise sampling
done at 0-15, 15-30, 30-45 cm every five years. Normally 0-15cm soil
is collected every other year.

c) Soil measurements made and frequency

Total carbon: Every 2 years
Method of measuring total carbon: Oxidizable C is determined by
wet-digestion method of Walkley and Black (1934) Soil Sci. 37:
29-38. This method is 60-70% efficient.
Ammonium nitrogen: Every 5 years
Method of measuring ammonium nitrogen: Distilling ammonia by
alkaline permanganate method of Subbiah & Asija (1956) Current Science
25: 172-194.
Soil bulk density or weight: Every 5 years.
Method of measuring soil bulk density or weight: Soil samples are
collected with a core sampler and dried to a constant weight. The
ratio of dry weight of soil to core volume will give bulk density.
Other nutrients: DTPA extractable Zn, Mn, Fe, Cu estimated in
1987-88. Available P and K were estimated at an approximate frequency
of 5 years.
Other measurements: Plant (grain and straw) samples analysed for
N, P & K content. Occasionally, soil samples are analysed for
infiltration rate and other physical parameters.

d) Details of the meteorological station

Nearest meteorological station to the site: Meteorological Laboratory,
CCSHAU, Hisar which is 1 km from the site at coordinates
75deg.46min. East, 29deg.11min. North. The meteorological station is manual.

e) Meteorological data available and frequency

Rainfall: Daily
Air temperature: Daily
Soil temperature: Daily
Wind speed: Daily
Sun hours: Daily
Relative humidity: Daily
