Description A field experiment \ofas conducted during kb.ari:t' 1988
in wetland block of s.v. Agricmltural College_farm, 1'1ru~ti
(A.P) under rainfed conditions on a sandy loam soil (having
low available N, utedium available P) with an object' ive o£
studying the "INFLUENCE OF FARr.trARD MANURE, ~IOGAS DIGES~
AND PHOSPHORUS ()N NU'J.'RITtON OF BLAC~ (Y&ID! ;nnsg L. Hepper)•~
he eXperiment was laid ot~ in a randomized block design with
thr~e ~eplications. Thera were 10 treatments comprising of
two levels of.P (P0 & P15•65} and 3 leyels of each of far~ard
manure l(E'YM) ·.ana· biogas· digest (BGD)· (o·,. 5 and 10 tonnes ha-1 ).
A aignitioant increase in &eed yield and dry matter
production of blaokgram s observed with the application of
organic matter (FYM/BGD). Increased dose of organic matter
application also resulted in a signi.ticant increase in the
yield as well as dry matter production, Among the two sources
of organic ms:~ter (FYM/BGD), BGD was .follnd superior to FYM
at their respective levels of application. The phosphorus
application ® 15.65 kg na•1 significantly increased the
grain yield and dry matter production over oon"t;rol. The
·combined application of organic matter and phosphorus had
s igni.f'icantly increased the grain yield and dry matter
production over the application of either organ!he matter or
phosphorus alone.
The concentration and uptake of nutrients (N, P,. K,
Ca, Mg and S) were significantly increased due to application
of either organic matter or phospho"ts over the control. the
uptake of these nutrients closely tollo\'led the dry matter
production trend. 'l'he maximum nutrient concentration and
uptake were observed when BGD was appUed @ 10 tonnes ha•1
in combination with P at almost all stages of the crop gr~rth.
The mioromttraients (Fe, Mn 1 Zn am Cu) content and uptake also
s1gn1:f'1cantly increased due to the application of organic
matter (FYM/BGD), Among the organic matter sources BaD was
found superior to mt in maintaining the higher micromttrient
concentration in blackgram.
In soil, tha maxinnun available N content \fas observed
at the time of harvest in mamtred plots, \1hereas the maximum
available P was observed at 45 DAS in all the plots. ~he
availability of both N and P in soil was significantly increased
due to organic matter applioa tion ® 1 0 tonnes he. -1 • The appli•
cation of phosphorus@ 1,.65 kg ha•1 increased the available P
in soU signi.f'.f.caatl.y. The available K content gradually
decreased upto ha.Mest. Organic matter application did not
1n:tluenoe the K av !lability in the soil at harvest. The
organic matter application@ 10 tonnes ha•1 resulted 1n a
significant increase in the micronutrient content of soil
