A field experiment entitled “Effect of Liquid Organic Manures Spray on Growth and Yield of Maize (Zea mays L.)”was carried out during Kharif season of 2023 at Agriculture Farm, Nalanda College of Agriculture, M.R. Palayam, Tiruchirappalli (District), Tamil Nadu. The experiment consisting of ten treatments viz. Control (T0), Panchagavya @ 3% (T1), Jeevamurtha @ 3% (T2), Fish amino acid @ 3% (T3), Panchagavya @ 5% (T4), Jeevamurtha @ 5% (T5), Fish amino acid @ 5% (T6), Panchagavya @ 8% (T7), Jeevamurtha @ 8% (T8) and Fish amino acid @ 8% (T9) was laid out in Randomized block design with three replications. Maize variety, Pioneer 30B07 was used as a test crop.
The results of one- year study clearly showed that organic foliar spray treatments brought significant effect in increasing growth, yield and economics of maize. Maximum plant height, dry matter accumulation, chlorophyll content, number of kernels per cob, grain yield, stover yield, harvest index, nitrogen, phosphorus and potassium content and their uptake by seed and stover, net returns and B:C ratio of maize was obtained by application of Fish amino acid @ 5% (T6) which was closely followed by Jeevamurtha @ 8% (T8). The plant height and dry matter accumulation at 30 DAS, test weight and harvest index of maize remained unchanged due to different treatments. Thus, for increasing productivity and profitability of maize, application of Fish amino acid @ 5% (T6) or Jeevamurtha @ 8% (T8) were found equally effective.
