throughout the growing season. Field experiments were conducted on microirrigation
fertigation in garlic crop during the crop growing season of 2008-09 and 2009-10
year (both drip and micro sprinklers). Four levels of nitrogen treatments namely
0, 40, 80 and 120 kg N ha-1 with three replications were applied
in both the methods of irrigation in Randomized Block Design (RBD). Water requirement
of garlic crop was estimated by using Penman-Monteith method. Periodic soil
samples were collected along the lateral (at emitter, 12.5 and 25 cm from emitter
) as well as across the lateral (15 and 30 cm from the emitter) at three soil
depths (0-15, 15-30 and 30-45 cm) in both methods of irrigation. The plant samples
were also collected during the harvest in both the season. It was observed that
the soil water content was relatively higher in upper profile and near the emitter
in all the three observations at 24, 48 and 72 h after fertigation in both drip
and microsprinkler irrigation. The results revealed that N concentration in
active root zone (15-30 cm) in microirrigation was more than the initial N content.
In the same layer adequate nitrogen availability was observed. Available nitrogen
decreased from emitter to the boundary wetting zone in drip fertigation in contrary
to microsprinkler fertigation. Nitrogen leaching was higher in drip fertigation
than the microsprinkler due to more vertical movement of soil water leading
to the movement of the nitrogen beyond the root zone. Nitrogen balance for the
study indicated that leaching of nitrogen beyond the root zone increased with
the level of nitrogen applied in both the methods of irrigation.]]>Chakraborty, S.K.,19971615291538Ajdary, K., D.K. Singh, A.K. Singh and M. Khanna,2007891528Arulkar, K.P., S.C. Sarode and R.C.
