pulses, sometimes even failure of crops, as a result of drought/prolonged dry spells during crop
growing season. On farm studies indicated that inclusive of livestock (milch cow – cross bred
jersey) farmers was benefited by getting additional income from milch animals and crop
component. AICRPDA - Kovilpatti main centre is selected Thoothukudi district for rainfed
integrated farming system activities. It is a preferred district where the centre is located with
representation for rainfed condition. Kayathar and Kovilpatti blocks were selected randomly
for the RIFS studies. These blocks having more area under rainfed conditions. Similarly, three
villages are randomly selected from each of the selected block of the district. Priority was
given to the villages in the following order: villages having less than 10 % irrigated area >
villages having less than 20 % area > villages having less than 30 % irrigated area. AICRPDA,
Kovilpatti main centre surveyed totally 240 respondents from two blocks (6 villages). Sum of
123 farmers under rainfed (RF) situation and 117 under partial irrigated (PIR) situation from 6
villages of Thoothukudi district. Each 37 marginal farmers from RF and PIR, 40 small farmers
from RF and 38 from PIR and 45 medium farmers from RF and 42 from PIR. Finally, 24
farmers from Vadakupatti village of Kovilpatti were selected for implementing the on-farm
research activity. Under each farming situations and farming systems, two farmers each in
marginal, small and medium categories were selected to implement the RIFS activities.
Results
Among the module examined, the results revealed that in rainfed situation crop + large
ruminant (milch cow-cross bred jersey) with intervention were recorded a maximum maize
equivalent yield, net return and employment generation in marginal farm holdings (14423
kgha -1 , Rs.119404 and 402 Man days) and small farm holdings (20407 kgha -1 , Rs.169253 and
521 Man days)respectively over no intervention. In Partially Irrigated situation the module,
crop + large ruminant (milch cow-cross bred jersey) with intervention were recorded a
maximum Maize Equivalent Yield, Net Return and Employment generation in marginal farm
holdings (25019 kgha -1 , Rs.193477 and 512 Man days) and small farm holdings (28557 kgha -1 ,
Rs.267956 and 689 Man days )respectively over no intervention.
