| In a field
experiment conducted in Faizabad, Uttar Pradesh, India, during 1995-96,
the effect of irrigation and mulching on growth of aonla (Emblica
officinalis [Phyllanthus emblica ]) cv. NA 7 was investigated. The
treatment comprised 3 irrigations (daily drip irrigation, alternate day
drip irrigation and conventional surface irrigation by basin method) and
different types of mulching materials, i.e. 200 guage black
polyethylene, 8-cm thick farmyard manure (FYM), paddy straw, grass, and
unmulched control. Plant height, canopy spread and stock girth were
significantly better under alternate day drip irrigation over
conventional method. Among mulching treatments, black polyethylene was
the most effective mulch material however, among organic mulches paddy
straw was the best for the same parameters. Leaf nutrient content (N, P,
K, Ca and Mg) was maximum in alternate day drip irrigation and minimum
under conventional method. Among mulching treatments, the maximum P, K,
Ca and Mg values were found in FYM whereas, the level of nitrogen was
more in paddy straw. |
