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 |
