There are Five Systems of Plantings
1. Rectangular system
2. Square system – all over India it is adopted
3. Diagonal system or Quinounx
4. Hexagonal System
5. Contour system
(1) Rectangular system : In this method trees are planted in a straight line (row) giving a straight angle only. It is suitable for grapes in Maharashtra.
(2) Square system : In this method a tree is planted on each corner of square. Intercultivation in both way is easy in this method. Plant to plant and row to row distance is same.
(3) Diagonal system : In this method at the centre of each square a tree is planted (filler tree).
(4) Hexagonal system : Also known as triangular system In this system the trees are planted in each corner of an equilateral triangle system ways, the six trees form a
hexagon with he seventh tree in the centre. This system allows planting of 15% more trees than square system.
(5) Contour system : It is usually followed on the hills with high slopes. In this method trees are planted across the slopes. Contour Trencher are dug out across he slopes and trees are planted. The points having same altitude are connected together by a line & the trees are given spacing on this line. This retards he ill effects of erosion.

#NREGA
National Rural Employment Guarantee Act The National Rural Employment Guarantee Act, (NREGA) was notified on September 7, 2005.
The objective of the Act is to enhance livelihood security in rural areas by providing at least 100 days of guaranteed wage employment in a financial year to every household whose adult members volunteer to do unskilled manual work.
i)Strong social safety net for the vulnerable groups by providing a full-back employment source, when other employment alternatives are scarce or inadequate;
ii)Growth engine for sustainable development of an agricultural economy. Through the process of providing employment on works that address causes of chronic poverty such as drought, deforestation and soil erosion, the Act seeks to strengthen the natural resource base of rural livelihood and create durable assets in rural areas Effectively implemented, NREGA has the potential to transform the geography of poverty.
iii) Empowerment of rural poor through the processes of a rights-based Law.
(iv) New ways of doing business, as a model of governance reform anchored on the principles of transparency and grass root democracy. Thus NREGA fosters conditions for inclusive growth ranging from basic wage security and recharging rural economy to a
transformative empowerment process of democracy.

#Methods_of_Sowing
Seeds are sown directly in the field (seed bed) or in the nursery (nursery bed) where seedlings are raised
and transplanted later.
Direct seeding may be done by
(a) Broadcasting.
(b) Dibbling
(c) Drilling.
(d) Sowing behind the country plough
(e) Planting
(f) Transplanting
(a) Broad casting - Broad casting is the scattering or spreading of the seeds on the soil, which may
or may not be incorporated into the soil. Broadcasting of seeds may be done by hand, mechanical spreader or aeroplane. Broadcasting is the easy, quick and cheap method of seeding.
The difficulties observed in broadcasting are uneven distribution, improper placement of seeds and less soil cover and compaction. As all the seeds are not placed in uniform density and depth,there is no uniformity of germination, seedling vigour and establishment. It is mostly suited for closely spaced and small seeded crops.
(b) Dibbling - It is the placing of seeds in a hole or pit made at a predetermined spacing and depth
with a dibbler or planter or very often by hand. Dibbling is laborious, time consuming and
expensive compared to broadcasting, but it requires less seeds and, gives rapid and uniform
germination with good seedling vigour.
(c) Drilling - It is a practice of dropping seeds in a continuous definite depth, covering them with soil and compacted finally
Sowing implements like seed drill or seed cum fertilizer drill are used. Manures, fertilizers, soil
amendments, pesticides, etc. may be applied along with seeds. Seeds are drilled continuously or
at regular intervals in rows. It requires more time, energy and cost, but maintains uniform
population per unit area. Rows are set according to the requirements.
(d) Sowing behind the country plough - It is an operation in which seeds are placed in the plough furrow either continuously or at required spacing by a man working behind a plough.When the plough takes the next adjacent furrow, the seeds in the previous furrow are closed by the soil closing the furrow.Depth of sowing is adjusted by adjusting the depth of the plough furrow. e.g.,
ground nut sowing in dry land areas of Tamil Nadu.
(e) Planting - Placing seeds or seed material firmly in the soil to grow.
(f) Transplanting - Planting seedlings in the main field after pulling out from the nursery. It is done to reduce the main field duration of the crops facilitating to grow more number of crops in an
year. It is easy to give extra care for tender seedlings. For small seeded crops like rice and ragi which require shallow sowing and frequent irrigation for proper germination, raising nursery is the easiest way.
