mustard seed equivalent yield and recorded 63 and 91% higher over no irrigation (857 kg ha -
1
), respectively. Similarly, among the different crops, lentil crop obtained highest net returns
(Rs. 56359.00 ha -1 ), benefit cost ratio (3.37) and water use efficiency (1.775 kg seed Cum -1 ).
Further, application of one supplemental irrigation at 45 DAS was recorded higher WUE (1.377
kg seed cum -1 ) as compared to two supplemental irrigations at 45 DAS & 60 DAS (0.944 kg
seed Cum -1 ) but higher soil moisture content was recorded under two supplemental irrigations
at 45 DAS & 60 DAS at all the three depth in all three crops at harvest in comparison to one
irrigation and control. This might be attributed to that increase in mustard seed equivalent is
not in proportion to the amount of supplement irrigation water. Therefore, it may be concluded
that growing of lentil crop during rabi season with one supplemental irrigation at 45 DAS is
more beneficial to get the higher production in semi-arid regions.

Rain Water Harvesting Technology, Jalkund - A Boon for Far Flung Hilly

Hnahthial village of Lunglei District has a total geographical area of about 16 sq km. The
average annual rainfall is about 2000mm.The village receives high rainfall but lacks rain water
harvesting structures and management leading to severe water scarcity, particularly during the
post monsoon season (November -April). Rainwater storage and harmonious Water Use
Efficiency (WUE) are the key to sustainable livelihood in the village. Under NICRA Project,
KVK Lunglei demonstrated 75 numbers of low-cost rain water harvesting technology
‘Jalkund’ in NICRA adopted village and its adjoining villages. The low-cost material like
Polyethylene pond liners (200 GSM) was used to construct pond generally with a size of
5x4x1.5m. The storage capacity of these tanks is in the range of 30000L 3 . Construction of
Jalkund and recycling of water through this system increase the productivity of the farmers
by diversifying farming system like crop and livestock. As noticed in Hnahthial and its
satellite villages, Jalkund technology had uncountable big and small impacts on the livelihood
of the farmers.
