Groundnut based Cropping Patterns:

i. 70 m. ha – Gujarat, A.P., T.N., Karnataka

ii. Grown mainly in rainfed conditions – 9 cropping patterns.

iv. Kharif and rabi sorghum and small millets are alternative – Maharashtra.

v. Sorghum, Cotton, tobacco sugarcane – Karnataka.

Cropping System:

It represents cropping patterns used on farm and their interaction with farm resources, farm enterprises and available technology to determine the farm makeup.

Cropping Pattern:

Proportion of area under various crops at a point of time in a unit area.

Types of Cropping Systems:

1. Monocropping (or) Monoculture

Growing of only one crop on a piece of land year after year.

Reasons:

(i) Climatological and socio economic conditions.

(ii) Specilization of farmer growing particular crop.

2. Multiple Cropping:

i. Intensification of cropping for both time and space dimensions.

ii. Growing two (or) more crops on the same piece of land in one calendar year.

Types:

(a) Intercropping:

i. Growing two (or) more dissimilar crops simultaneously on the same piece of land in a definite row pattern.

ii. Cropping intensity in space dimension is achieved.

Intercropping is of two types —

(i) Additive Series

(ii) Replacement Series

(i) Additive Series:

a. One crop sown as a base crop.

b. Another crop introduced into base crop by adjusting (or) changing crop geometry.

(ii) Replacement Series:

a. Both the crops are component crops.

Requirements – Successful Intercropping:

(i) The time of peak nutrients demands of component crops should not overlap. e.g. Maize + green gram. Green gram – peak demand period – around 35 DAS. (Days after sowing)

Maize – Peak demand period – around 50 DAS.

(ii) Competition for light (solar radiation), nutrients, air space are minimum among component crops.

(iii) Complementary should exist between the component crops.

On the basis of above knowledge, suitable combinations are.

Principal Crop

Intercrop

Sugarcane

Wheat, Cowpea, Soybean, Moong, Sunflower

Sorghum

Cowpea, Soybean, Moong, Urd, Arhar

Maize

Cowpea, Soybean, Urd, Arhar. Castor

Bajra

Cowpea, Soybean, Urd

Cotton

Soybean, groundnut

Potato

Wheat, radish

Advantages

(i) To raise productivity per unit area.

(ii) Better utilization of growth resources – nutrient, water, light, air.

(iii) Additional income from component crop.

(iv) Quick growing component crops, suppress harmful weeds by thriving in the interspace of base crop.

(v) Gainful utilization of labour – increasing more man days employment potential.

(vi) Less incidence of insect pests and disease attack.

(vii) Less erosion losses.

Disadvantages:

(i) Fertilizer management is difficult because nutrients requirements is different for different crops.

(ii) Difficult in harvest – different seeding time for different crops.

(iii) Certain circumstances (e.g. allelopathy) – one suppress growth for another crop.

(b) Mixed Cropping:

i. Growing two or more dissimilar crops simultaneously intermingled without any row pattern.

(c) Sequential Cropping:

i. Growing of two or more crops in sequence on the same piece of land in a farming year.

ii. Succeeding crop is planted after preceding crop harvested

(d) Relay Cropping:

i. Planting of succeeding crop before the harvest of preceding crop.

(e) Ratoon Cropping (or) ratooning:

i. To raising a crop with regrowth coming out of roots or stalks after harvest of the crop. e.g. – sugarcane, fodder, grasses.

(f) Multistoried Cropping/Multilevel Cropping:

i. System of growing crops of different heights together at the same time on same piece of land.

ii. Using land, water, space most efficiently or economically.

E.g. Coconut + pepper + grasses,

Coffee + banana + arhar.

3. Crop Rotation::

i. Recurrent succession of crops on the same piece of land either in a year (or) longer period of time, to get maximum profit with least investment and without impairing soil fertility.

Principles for Successful Rotation —

i Crop with tap roots and fibrous root system.

ii. Leguminous crops with non-leguminous crop.

iii. Selection of a crop based on demand of people of that area.

iv. Selection of crop should be problem based.

(a) Sloping lands – alternate cropping of erosion promoting crops with erosion resisting crops.

(b) Dryland (or) partially irrigated area – crops which can tolerate drought e.g. oilseeds and pulses.

(c) Low lying (or) flood prone area – crops which can tolerate water stagnation e.g. Rice, jute.

Advantages:

i. Proper utilization of all the resources and inputs.

ii. Helps in controlling insect pests, diseases and weeds.

iii. Agricultural operation done timely for all crops.

iv. Soil fertility is maintained.

v. Get better price for produce.

Impact of Cropping Patterns:

Factors responsible for Changes in Cropping Patterns:

i. Development of high yielding and short duration varieties in main crops.

ii. Development of production technology to grow them.

iii. Incentives and innovations provided by central and state govts.

iv. Spread of irrigation.

v. Development of fertilizer production and technology.

vi. Govt’s special programmes – enhancing production of particular crop.

vii. Changes in the socio-economic conditions of the people and rapid industrialisation in the country.

viii. Transformation of subsistence agriculture into market oriented economy.

Negative impacts of – Changes in Cropping Patterns:

i. Introduction of HYV and short duration varieties. Consequently led to intensive cropping and resulted in decline in fertility and deficiency of Zn, Mn in Punjab due to introduction of paddy-wheat rotation cropping.

ii. Cause more incidence of insect pests and weeds.

iii. More use of fertilizers – environmental pollution and salinity.

iv. Increased use of irrigation water-salinity and water logging.

v. Indiscriminate use of pesticides – adverse effects on environment and microorganisms.

vi. Resistance of insects and pathogens towards.

vii. HYV – rice, wheat pushed pulses and oilseeds to marginal areas.
