Abstract
A filed experiment entitled “RESPONSE OF NITROGEN LEVELS AND
ENRICHED COMPOST TO GRAIN AMARANTH (Amaranthus
hypochondriacus L.) UNDER SOUTH SAURASHTRA CONDITION” was
conducted during rabi season of the year 2017-18 at the Instructional Farm,
Department of Agronomy, College of Agriculture, Junagadh Agricultural University,
Junagadh. The experiment comprising eight treatment combinations were laid out in
factorial randomized block design and replicated thrice. The treatment consisted
combinations of four levels of nitrogen viz., 00 kg N/ha (N1), 40 kg N/ha (N2), 60 kg
N/ha (N3) and 80 kg N/ha (N4), two levels of enriched compost i.e. no enriched
compost (C1) and enriched compost 5.0 t/ha (C2). The recommended dose of
phosphorus 40 kg P2O5/ha was applied uniformly to all the treatment as basal in form
of single super phosphate. Nitrogen was applied as per treatment in form of urea.
Experimental results indicated that significantly highest plant height, number
of leaves per plant, leaf area index and dry matter accumulation at 30 DAS, 60 DAS,
90 DAS and at harvest, while stem girth at harvest and days to 50% flowering were
significantly higher with an application of 80 kg N/ha (N4). Similarly, significantly
more length of main inflorescence (85.12 cm), higher number of spikelets per spike,
maximum test weight and highest grain yield and stover yield recorded by nitrogen
application 80 kg N/ha (N4).
Fertilization with 80 kg N/ha recorded significantly highest protein content
and protein yield. There was not found any significant influence of different levels of
nitrogen on phosphorus and potassium content in grain as well as in stover but
nitrogen content in grain and stover shows significant result. While application of nitrogen 80 kg N/ha (N4) showed significantly highest nitrogen, phosphorus and
potassium uptake by grain and stover.
