System of rice intensification (SRI) has been gaining momentum over the years in Tripura, one of the eastern states of India. To meet the growing rice demand, a rapid increase in paddy production is needed. Considering the growing importance of System of Rice Intensification (SRI) in the state, the need for such a study was felt and accordingly the present study was conducted in Sepahijala district of Tripura on the basis of highest area coverage under SRI among all districts of the State. SRI offers an interesting alternative to improve rice productivity. The present study was carried out to examine the comparative economics of SRI and conventional methods of rice cultivation in Tripura, India during the year 2016-17. For the study 120 sample farmers were selected by using multistage random sampling. The cost concepts were used are Cost A, Cost B and Cost C. This paper has compared the economics of SRI and the conventional methods of rice cultivation. It has shown that gross return and net return were much higher for SRI (Rs. 129000.50), (Rs. 67050.50) than conventional (Rs. 78444.00), (Rs. 27168.00), respectively. Similarly, the return over cost was higher for SRI (2.08) than conventional (1.52) methods. The present study concludes that SRI has a tremendous potential to increase the production of rice. Moreover, adoption of this technique by the farmers would give them higher yields which in turn will help them to earn more and improve their socio-economic situation. It has proved to serve as an alternative method for rice cultivation.

In this paper an attempt was made to analyze economics of paddy cultivation in Cuddalore district. Based on area under paddy, three blocks namely Kurinjipadi, Kumaratchi and Vridhachalam were selected. The total sample size was 120 paddy growers. The study revealed that area and production of paddy crop was declining during the period 1998-2008 while the productivity was growing positively during the same period. During 2009-2019, compound growth rate of area, production and productivity of paddy was depicting an increasing trend due to the role-played by high yielding varieties which created greater affinity towards paddy crop. The cost of production of paddy per hectare was estimated to be Rs. 56,617. The average gross income was found to be Rs. 92,077 per hectare and net income was observed to be Rs. 29,712 per hectare. Excessive usage of nitrogen and phosphorous fertilizers could be reduced to decrease the production cost and increase the efficiency of inputs. Adoption of System of Rice Intensification (SRI) method was suggested to increase the productivity of paddy.

Rice Intensification

The development of plant roots is known to play a very important role in the uptake of water and nutrients by rice plants. However, there are few studies on what changes, if any, are induced in the rooting systems of rice plants under System of Rice Intensification (SRI) management. This research evaluated changes of rice roots with SRI method compared to conventional method of irrigated rice cultivation and assessed influences that could improve rice yield. Under SRI management, plant roots were significantly longer and heavier than with conventional method. SRI method also increased the number of root hairs by 60%, and root hairs were healthier and more vigorous compared with conventional method. However, root respiration was not different in the two methods. There was less formation of aerenchyma (air pockets) in rice roots with SRI method, as both the number and size of root aerenchyma were lower with SRI than with conventional method. The SRI method was able to improve the root length, root dry weight compared to the conventional method. The SRI method was also able to increase the number of root hairs by 60% compared with the conventional method. Eh measurements in the soil with SRI method were higher than with conventional method. However, there was no significant different in root respiration. The aerenchyma formation of rice roots in SRI method was lower than conventional method.

Paddy Cultivation

The System of Rice Intensification (SRI) developed in Madagascar in 1980s is a revolutionary new idea for paddycultivation to increase yields with reduced external resources. Basic idea of SRI originally proposed (Basic SRI) is to applycombination of (a) transplanting of young seedlings with wider spacing and (b) intermittent irrigation during vegetativegrowth period Further, application of organic fertilizers without use chemicals has practiced as "Organic SRI" as an idealapproach to improve soil and to produce high quality rice. Over the past fIVe years, a Japan-funded irrigation project inEastern Indonesia executing by the Directorate General of Water Resources, the Ministry of Public Works has introduced SRIand assessed it's potential to reduce demandfor irrigation water while rewardingfarmers with higher production and incomes.This paper reports on on-farm comparative evaluations conducted over 9 seasons between 2002 and 2006 across 8 provincesunder DISIMP. It summarizes the results of 12,133 comparison trials that covered a total area of 9,429 hectares. Averageyield increase was 78% (3.3 tlha) with reductions of 40% in water use, 50% in fertilizer applications, and 20% in the costs ofproduction. As a conclusion, SRI practices can achieve significantly higher output of rice with a reduction in inputs, enhancingsimultaneously the productivity of the resources (land, labor, water and capital) used in irrigated rice production. Theeconomic attractiveness of SRI methods is very great, giving farmers strong incentive to accept water-saving as new norm forirrigated rice production.

A field trial was conducted at Al-Mishkhab Rice Research Station at Najaf Governorate during 2015 season to assess the effects of irrigation periods and organic manure on yield and its components of two local rice varieties (Anber 33, Jasmine) under System of Rice Intensification (SRI). The experiment was conducted using split split plot arrangement with RCBD design with three replicates. The main plots were irrigation methods where practiced: continuous submerge and intermittent water application where irrigation water was scheduled at two different intervals 3, 5 days. The sub plots were varieties (anber33,jasmin) and three amount of organic manures 0, 5, 10 ton.haˉ¹, planted under System of Rice Intensification (SRI) compared with conventional method (farmer practice). Transplanted method was done when (SRI) implemented and seedlings were transplanted by pattern square 25×25cm between other with one seedlings per hill and early transplanted 15 days seedling old. The conventional method were closed randomize space (10- 15)cm with more than one (3-5) seedlings, and late transplanted (30 days) seedling old. The results indicated that can be save amount of water and obtain of high yield by 29.5% with less water consumption by 57.6 % was used irrigation intervals of 3 days compared with continuance submerge, and then the amount of water consumption with 3 days interval was 3.67 mm equal 36.762 m³.haˉ¹, with 5 days interval 3.18 mm equal 31.869 m³.haˉ¹, with continuance submerge 8.66 mm equal 86.678 m³.haˉ¹. Also the results indicated that the water use efficiency (WUE) with irrigation interval 5 days was  31869 kg m-³ , with 3 days interval was  36762kg m-³ , with continuous submerge was  86678 kg m-³. The WUE Increase was with 3 days interval 70 %, and then the water consumption was reduced 2.2 compared with continuous submerge. The results indicated that there were significant differences with growth parameters (plant hight, and dry matter weight) and significant differences with yield and its components (Panicle number per m², grain number per panicle, 1000 grain weight, sterile percent, grain yield, and harvest index) when used 3 days intervals and 10 ton.haˉ¹ organic manure.

Four hundred and sixteen on-farm demonstrations on system of rice intensification (SRI) were carried out in 350 hectares of farmer’s fields in Sankarankovil, Vasudevanallur and Kuruvikulam blocks of Tirunelveli district of Tamil Nadu from 2008-09 to 2010-11 under Tamil Nadu – Irrigated Agriculture Modernization and Water Bodies Restoration and Management (TN-IAMWARM) project. Two methods viz., SRI and conventional were compared. The results revealed that the adoption of SRI favorable influenced yield attributes and yield of rice. The maximum grain yield (8222 kg ha-1) obtained from SRI which was higher than conventional method (6534 kg ha-1). Higher grain yield coupled with substantial water saving to the tune of 37.1 per cent resulted in higher water use efficiency of rice under SRI method. The best net income ( Rs. 50, 587) and benefit: cost ratio (3.64) were also associated with SRI than conventional method of rice cultivation. The cost of cultivation was comparatively lesser in SRI which re-sulted in gaining an additional income of Rs. 8080 ha-1 as compared to conventional method of rice cultivation. The system of rice intensification (SRI) proved its benefits in this basin.
