......While the world population is increasing seconds by seconds, the area of the earth surface is remaining constantly and the resources getting reduced as such. Opportunities for livelihood also are not widening. How do we live our own in such a drastic situation? In such a situation, we think about self employment. Our ancient sector under societal life of mankind is invariably AGRICULTURE which can solve the basic need of mankind, FOOD, CLOTHINGS & SHELTER. The vegetation will exist without man, but not vice versa. Agriculture is a part of vegetation. Animal Husbandry is a subsidiary field under Agriculture.


.....In the modern society, it is quiet true that many people think to solve their unemployment issues through Agriculture and allied farming sector. They getting into pure agriculture operations and facing many troubles and cooping the threats of failure. Many are trying Animal Husbandry sector and facing the same. Both of them conclude that AGRICULTURE OR ANIMAL HUSBANDRY SECTOR UNSUCCESSFULL. How far it is true? Both the statements are true, unless AGRICULTURE AND ANIMAL HUSBANDY SECTORS BECOME COMPLIMENTARY TO EACH OTHER AND ARE INTERDEPENDENT.


.....Livestock farming will give more profit than Agriculture. But without agriculture, it will never give a coin. Now, it is our time to think about the INTERCROPING OF AGRICULTURE AND LIVESTOCK FARMING. Whatever the LIVESTOCK we prefer to rear, we should primarily bother about feeding them. To purchase all the ingredients of feed is unprofitable. So we should produce the feeding materials our own. CONCENTRATES AND ROUGHAGES are the two major components of livestock feeds. Roughages require in bulk quantity than the concentrates. That is why we cultivate fodder grass. (Concentrates also can be prepared by us cultivating certain fodder crops).


.....There are a number of fodder plants cultivated profitably. Hybrid Napier grass, Guinea grass, Congo signal grass, Para grass, Fodder sorghum, Fodder maize etc.  are some of the fodder grass varieties. Sesbania, Gliricidia, Desmanthes, Stylosanthes, Lucerne, Fodder pea, Lablab etc. are some of the leguminous fodder varieties.
As the Hybrid Napier is one of the widely cultivated fodder grasses, in this introductory session the Package of Practices of the cultivation of Hybrid Napier Grass in 1 acre land is detailed.
The Major pre-requirements for Hybrid Napier cultivation are water available land (even during summer too), whether it is Barron or not and soil loving man power.

PACKAGE  OF THE CULTIVATION OF HYBRID NAPIER GRASS
( Pennisetum typhoides x P. purpureum) = (Elephant grass X Bajra)

Introduction

.....Napier grass is also called as Elephant Grass due to its tallness and vigorous vegetative growth. The plants tiller freely and a single clump may produce more than 50 tillers under favourable climatic and soil conditions. Unfortunately, the grass coarse-textured, the leaf blade and sheaths hairy, leaf margins sharply serrated and stems less juicy and fibrous. In 1953, a cross was made in India between Bajra which is more succulent, leafy, fine-textured, palatable, fast growing and drought resistant and Napier to combine these qualities with its high yielding potential. 
Hybrid Napier is a perennial grass which can be retained on field for 2-3 years. Compared to Napier grass, Hybrid Napier produces numerous leaves. It has larger leaves, softer and less persistent hairs of leaf blades and sheaths and less sharp leaf edges. The stems are also less fibrous than Napier. The tillers are more numerous and grow faster (See figure 1).

Climate and soil

....The grass grows throughout the year in the tropics. The optimum temperature is about 31° C. Light showers   alternated with bright sunshine are very congenial to the crop. Total water requirement of the grass is 800-1000 mm. Hybrid Napier can grow on a variety of soils. Light loams and sandy soil are preferred to heavy soils. The soil has as to be wet at the root zone but should not be stagnated.  The grass does not thrive well on water logged and flood prone lands. Phenomenal yield are obtained from very deep fertile soil rich in organic matter and nutrient elements. It tolerates a pH range from 5 to 8. 

Land preparation

.....Clearing of the bushes, removal of thorns, weeds etc. are must be done at the beginning. Hybrid Napier requires a deep, thorough, weed free and compact seed bed. One disc ploughing may be followed by two or three fork ploughing, leveling and removal of clods . Basal application of farmyard manure is done before the preparation of ridges. Ridges are made across the slope far as possible at a spacing of 60 cm with a height of about 25 cm which enables irrigation uniform and easy.    

Manuring

.....Spread farmyard manure at the rate of 10 MT/Acre before ploughing. Apply fertilizer as per soil test recommendations. The standard recommendation for a barren land is as follows:
N:P:K @ 8:10:5 kg/Acre as basal application.
The above fertilizer recommendation can be given at the time of the first weeding, normally30 days after planting.

Varieties

.....The popular Hybrid Napier are CO-3 and KKM-1. Among these, CO-3 variety is widely cultivated. The most popular Hybrid Napier variety, CO3, has been released from Tamil Nadu Agricultural University during the year 1996 with an expected yield of 400 MT / Ha /Annum. 

Spacing and seed rate

.....The spacing recommended and adopted is 50 cm X 50 cm.
16000 cuttings are planted per acre.

Planting
.....Planting is done with the onset of monsoon or any time, if irrigation facility is available. Being a sterile hybrid, the grass is planted by rooted slips or by stem cuttings. Cuttings with 2 nodes from the middle portion of moderately matured stems (3 – 4 months old) are preferred. The cuttings are planted at a slanting position at one side of the ridges with one node buried in the soil (See figure 2&3).  The underground node develops roots and shoots while the upper node shoots only.  The soil around the stem has to be pressed tightly for better root growth.

Top dressing
.....Application of Nitrogen @ 30 kg/acre after every harvest with gentle raking of the soil produces more tillers. 

Irrigation and drainage
.....The field should be provided with good drainage during the rainy season as the crop cannot stand water stagnation. The first irrigation is done at the time of planting and the life irrigation on the 3rd day after planting. Frequencies of subsequent irrigations depend upon the rainfall and weather conditions. The standard irrigation interval during summer is 3-4 days (depending upon the soil quality).

Weed control
.....Weeding should be done within 30 days of planting and second weeding is essential only if there is heavy weed growth (See figure 4).

Harvesting
.....The first cut is taken from 60 to 75 days after planting. Subsequent cuts are taken after 30-45 days or when the plants attain a height of 1½ m (See figure 5).  Annually at least 6 to 8 cuts are possible. The fodder has to be cut closer to the ground level for more profuse tillering.

Yield
100  - 150  MT/acre/year  green  fodder  is  obtained  on  an average if it is cultivated as a single crop. Hybrid Napier can be cultivated as a single crop or intercrop with banana etc. (See figure6). Vegetative growth is reduced to dormant during winter.

Nutritive value (Approximately)
Dry matter                          16.20 %
Crude Protein                    9.38 %
Calcium                                0.88 %
Phosphorus                        0.24 %
Oxalates (Max.)                2.97 %
Digestibility                         58.00 %

Herbage quality

Leaves (Foliages) are larger and greener, sheaths are softer, and margins are less serrated; so the herbage is more palatable. It is juicier and succulent at all stages of growth. It is less fibrous and more acceptable.

 Few important to be remembered:

  • Hybrid Napier should be recommended to places only with copious irrigation facility from February to May.
  • Soil reclamation with lime is essential in acidic soils.
  • While planting, the soil around the cutting has to be pressed tightly for good root growth.
  • The grass must be cut at ground level for good tillering of the clumps.
  • Raking the soil, earthing up and removing dried   tillers after every three harvest is essential for good establishment.
  • Economically viable for 3 years.
