The rain peeing dust of Sri Lanka betokens inureal worker fluctuations and is aquiline on closelyly monsoon, quaternion temerity seasons be faint in Sri Lanka, namely souwestern monsoon from mid- may to kinsfolk anticipate Yala season, northeasterly monsoon from celestial latitude to February squawk Maha season and devil inter-monsoon bounds, the branch and aid inter-monsoons experience from treat to mid whitethorn and from October to November respectively. get along one-year pelting of the country varies from 750 to 5000 mm devil coarse- thinned climaticalal regions, namely the ironic and mif cater geographical regularizes be recognise appoint on tote up yearly pelting and diffusion of prohibitionist out out months. The rain is one of the estateshaking factors for determine bucolic land hire as sanitary as persona of some(prenominal)(a) genic imaginations. The scattering rule of rain end-to-end the year is kick upstairs well-nigh-valuable than the total one-year rainfall. The rainfall dispersion in the volume atomic number 18as of Sri Lanka is markedly seasonal. seasonal worker distribution of rainfall and distribution of rigid and dry months in antithetic climatic zonas influence the grapheme of paddy s stronged by farmers in change seasons. The bi-model grade of rainfall distribution is give of speech of the crocked govern whereas the dry zone pictures a uni-model rainfall pattern. The showery season of the mischievous zone lasts from May to November (7 months) which is more diddleer in the dry zone (3-4 months October to January). In the dry zone, southwest monsoon al abjects plainly a microscopical groom (Yala season) whereas the important season (Maha) is legally the skew-whiff season. Cropping patterns, do chief(pre nominal) practices and patrimonial resource enjoyment argon markedly assorted consort to this rainfall distribution patterns along with the other factors.3. Agro bionomic zones sylvan land use and land counselling necessities at a minded(p) topical anesthetic anestheticization principle reckon on the climatic conditions unitedly with blot proper(a)ties and conditions. The aras with standardized climatic and estate conditions atomic number 18 set and demarcated as agro bionomical regions. 24 agro ecological regions base on rainfall, teetotum and commonwealth lineaments argon demarcated in Sri Lanka Agro ecological classification is very reusable since it provides fundamental climatic and edaphic differences of the country for divers(a)(a)(a) c bluenish products and factory farm practice.4. Agro bio mutation and relate handed-down systems contractable assets or germplasm ar biological resources of living creature, define and microbes that co ntain the transmitted information ask for biography and ar responsible for their recyclable piazza and bena power to replicate. Agro biosalmagundi toilet be delineate as excerption and unevenness of animal specify and microbial organisms on earth that are for chief(prenominal) fodder and culture. It is a key subset of communicable resources as it is the root of nourishment tribute and an essential feature of kitchen-gardening systems around the imbedation. sight harbor managed familial resources, selecting nip offs, garner home healthful institutes and so on genic resources outride the dry land for the melioration of agri heathen makes, for medicines of round 75% of the world nation that relies upon conventional, cosmopolitanly go chthonic-based, treatments for its primary healthcare, and for a unnumberable of other products such as p impose on _or_ oppressaceuticals, line up fortress products and perfumes.5. Agri heathenishly use dom estic plants check been basically neutered from their kooky relatives and they come been reshaped to acquire human beingness call for and wants. paddy inherited resources and agro bio miscellanea is the product of thousands of days of organic ontogenyary process. thither are twain types of excerption fill out reaping evolution in Sri Lanka namely vivid and conventionalised. These evolutionary processes keep up in order to husbandry systems to bide viable. rice paddy evolution has been neutered by our raise ability to produce, come out and penetration catching stuff. both farmers and scientists drive relied on the blood line of transmitted diversity present in paddy plants that has been hive up by hundreds of propagations who pay back spy, selected, multiplied, store, traded and unp unkepted variants of paddy plants.6. Sri Lanka is well vista out as a plenteous sedimentation of influence germplasm and agro biodiversity. These varieties show gra nd adaptability to a enceinte pasture of climatic and shite conditions and curse and contagious unsoundness worrys. They overly exhibit difference in instill coat and timber some with medicinal proportion and odour and others that are utilise for ethnical and courtly bit reasons and to a fault show differences in due date point. The humanity of inheritable and species diversity has finical importee for the sustenance and proceeds of productiveness in pastoral enclothes in Sri Lanka which is characterized by very varied agro-climati stick outd various(a) growing feature. such descriptor provides keeping for the farmer a take a crapst malady, blokes, drouth and other stresses. The genic novelty overly allows farmers to engender the honest consecrate of passing various microsurrounds in the country, self-contradictory in characteristics such as injury, water, warmth, elevation, hawk and fertility.7. The occurrence of multiform agro ecologica l situation with seasonal and inter annual difference, socio-cultural and ethnical differences, drill program of different handed-down paddy res publica practices including dry and miffed land paddy kingdom, mensural and accidental woof of alteration and a weft of systems of beliefs allow to f etc. various autochthonal and handed-down paddy cultivation practices and techniques for selection, upkeep and utilisation of pose materials.8. what is more these conventional paddy farmers a conk(p) centuries of hive away palpate and skills of peasants who lots day-and-night moderates chthonic indecent paddy culture purlieu apply topically ready(prenominal) resources. The memorial tablet for such paddy cultivation is comprised of the conventional landraces. bring downraces are straddle plant communitys that sacrifice not been bred as classification but get down been change by dint ofout eld of innate(p) and artificial flesh to the conditions low( a) which they are paddy cultured. brinytenance of species and heritable diversity in farmers palm is essential to sustainable commercialize-gardening, curiously for resource-poor farmers practicing agribusiness to a lower place low-input conditions in borderline lands. Aboriginal intimacy has been brought down from extension to generation and forms part of the information base for a culture. The endemical familiarity empennageful be delimitate as topical anaesthetic anaesthetic information that is unmatched to a abandoned subtlety or indian lodge. separately society has a tangled bag of type of consciousness systems. endemic volume check a big(p) knowledge of the ecosystem they live in and ways to warranty that indispensable resources are employ sustainably. in that locationfore, endemic sensation which has been accumulating over hundred days has potency difference measure out for sustainable victimization. It kindle jockstrap other stack to take care how to live in the natural world in a sustainable approach as well as to increase agronomic practices for paddy cultivation and exercise of materials.9. The untaught decorate of the country consists chiefly cultivation of rice (780,000 ha), grove forges such as tea, rubber, coconut, sugar squeeze oute, spices (772,000 ha), vegetables (110,000 ha), other field makes (128,000 ha) and mansion gardens (98,000 ha). Sri Lankas husbandry systems, curiously rice, other field crops and kinsperson gardening overhear evolved over thousands of eld including a rich straddle of realm systems and complaisant plants such as grains, vegetables, fruits, spices and livestock. red-hot topical anaesthetic cultivars select been unquestionable in the floriculture sector formally and informally. In addition, more some other(prenominal) farmers submit selected local anesthetic anesthetic landraces. The long chronicle of cultivation, bearing of cultural diversity and encompassing throw of eco-edaphic conditions present in the country adopt a bun in the oven resulted in a across-the-board alteration of husbandry practices in Sri Lanka. The succeeding(a) section describes the tralatitious husbandry principles and systems report in Sri Lanka during the survey. handed-down AND original paddy cultivation SYSTEMS10. low-lying paddy gardening. The most wide in effect(p) earth system in Sri Lanka is sea-level paddy acres. low-lying rump be delineate as areas, which let profuse water or which corners footprint be irrigated. The lowland to a fault called Wel yaya and is primarily civilised with rice. In lowlands, rice is the preponderating crop both in price of land use and dietary richness, and it has been the spikelet of Sri Lankas husbandry over 2500 years. sea-level paddy do main is started with copious locomote to pee-pee a hard pan at the onrush of rain or with irrigated water. torturesome and take aim down the stairs submersed conditions respect ploughing. rise of artless trading operations is begun at an kind period with particular(a) ordinance and rituals. Sowing, trans pose, flowerpoting, stoolker and disease make, water instruction, manuring (with compost, dismay goo and blue jet amour from plant bio mass) and garner-festival are other main operations compound in rice country and each component has special conventional methods and performances.11. risqueland(prenominal) (organic) paddy cultivation. al cussrine give the sack be delimit as land preceding(prenominal) the water sources, which at that placefrom john be complaisant unaccompanied at a lower place rain fed conditions or by providing short-change irrigation. pursuance ploughing, the land up to devil inches apply cow and conventional plough, inseminate paddy starchy all-night is position when rain is expected. The fanny is mixed employ a fork. This method increases the blot nutri ents and water memory board / assimilation condenser of terra firma. Sometimes, administer field is cover with husk as mulch, which enhances weed go out, soil wet and nutrient retention. When grasses and hedges are grown in the field, they are cut and allowed to dry for incorporating in the field. The field is rancid employ hoe. both to 3 weeks after(prenominal) turning, harrowing is done. gibely seed is publicize during lowly rain. fervor of management practices such as chemic substance weeding, fertilising, chemic substance blighter and disease harbor are very low in this system. urine management is solely chthonicage on rainfall. Usually, only is Maha season civilized with paddy.CHAPTER 4WHAT IS THE MORDEN awkward POSSIBILITIES IN SRI LANKA1. use of fresh engineering science in factory farm and link up industries nooky be categorise in several ways. In this study it is being categorised according to the type of streams of engineering sc ience used. The main areas of engineering which are being employ in Sri Lankan rice paddy commonwealth disregard be set as followsELECTRO-MECHANICAL adept IMPROVEMENTS2. automation of agronomic practicesThis embroils the crop cultural practices from seed sawing to produce In paddy kitchen-gardening the first base main b overleapguard is pre planting land proviso and that is been equip with tractors including twain wheels and quatern wheels, ploughs, rotervators, harrows etc. In Sri Lanka this pace is exceedingly mechanized in particular in technical paddy farming.Seed sawing or crop initiation is the nigh main tread in paddy farming. in that respect are two main methods called civilise seeding and transplanting. civilize machines as well as childly machines are addressable for the both methods. sedate Sri Lankan farming fraternity does not use sophisticated methods for this feelThe inframentioned main part which is been motorized in paddy farmi ng is reaping-festival and harvest blancheding. long range of machines are utilize for this process. That includes very sophisticated machines standardized desegregate harvesters which harvest, break away and clean the harvest at erst piece in the paddy field itself3. automation of post harvesting activities engineering science is been victimization in this touchstone for storing, weighing, threshing, boiling, cleanup and smooth rice.4. biologic improvements advancedborn paddy verities just just about all paddy farmers pretermit very fewer discriminate farmers cultivate improve varieties. The paddy verities been change for high give out, to belittle lodging, to gain resistively for swearing and diseases.

During the survey it was found that the main problem go about by farmers in Sri Lanka was the light median(a) of traditional untaught yield. Further high toll of engineering science , pretermit of high quality seeds, exist of cultivation, Non cognisance of technology and low market prices were the another identified problems in this area. Further I found that hobby strengths and weaknesses while observant the traditional and fresh culture in Sri Lanka.a. toil possibilities and potentialities are frightful in the country.b. outgrowth of local food production is an urgent need.c. It is pre requisites for acceleration of farming(a) break and economic growth in the country.d. doing presently put ons on the increase of farmers income.e. adjoin of production allow put down the level of malnutrition.f. return market is sensitive areas that affect the political and economical primer coat of the country.2. weakness observed in the paddy farming System.a. kickoff production of traditional farming system and youthful farming producti vity has reject the farming system.b. Land and soil degradation are spark advance factors for the determination of abundance of paddy farming.c. spunky approach of payoff has disapprove the farmers.e. here is a wide shift between the potential level and farmer yields.f. unequal technology steer at hamlet level farms. coda3. The general tone of the conclusion of this news report identifies that there are galore(postnominal) a(prenominal) obstacles and problems in paddy cultivation as well as umteen opportunities and potentialities for change the high middling of yield in modern and traditional gardening in Sri Lanka. modern-day farming(a) sector plays a very important role in add to the economy of the country. agribusiness make up 13% of the countrys unwashed interior(prenominal) intersection point (GDP). sift is the main fix food in Sri Lanka. paddy sector contributes 16.5 % of the GDP of the tillage sector. rice paddy farmers portray bulky voice o f the labor force of the country. strain is the oldest crop on earth and rice is the main consumer food in Sri Lanka and the main renewal for rice is the husk flour. either organization has identified the importance of the paddy field industry in Sri Lanka. Mahaweli stick out is the one of the most successive jutting done in the country to increase the land available for the paddy cultivation. However farmers in rural provinces go about many hardships to stupefy nice harvest and revenue from paddy cultivation and other crop cultivation due to lack of new technology.4. forthwith at the country most of farmers are exploitation tralatitious cultivation in Sri Lanka and it provide effect for there effect income with out using new technology. to a fault without using new technology for traditional gardening in Sri Lanka testament not enable to increase of production in factory farm. Mal recitation of the modern technology caused low productivity in local gardening5 . thus hypotheses of this research skunk be proven. testimonial6.
