Abstract: In these experiment, we aim to find out the biological parameter of the six crops taken viz. pearl millet (Pennisetum perpareum), yellow maize (Zea mays), Oat (Avena sativa), Barley (Hordeum vulgare), wheat (Triticum aestivum) and white maize (Zea mays) which were grown hydroponically to produce fodder and also some quality parameters like ADF and NDF. The research which was conducted in the April-May, 2016 in PGI farm of Mahatma Phule Krishi Vidyapeeth, Rahuri used a rack of 2.7 m x 1.5 m area. This rack was made of UV-PVC polypipe which held 54 trays of size 50 cm x 30 cm x 5 cm. factorial complete randomized design were the experimental design used. Foliar spray was done on 5th day to all the crops taking two different water soluble fertilizers urea @ 0.5 % and 19-19-19 @ 0.5 % and one was kept as control (no foliar spray) in each crop. So, all together the treatment combinations were eighteen. Water to the system was supplied by micro sprinkler/ jet irrigation applied at every regular intervals of 3 hours in all crops except pearl millet which needed only once in 4 hours. Better growth was recorded in foliar applied treatments than the control in all the crops taken. The plant height and root length growth was steady. The plant height and root length was highest in maize crops both yellow and white maize. In each crops taken 19-19-19 WSF sprayed treatment, the quality though was different from crop to crop on considering the best among all pearl millet and wheat showed better content than other crops. The ADF and NDF content were varied even among the same crop treatments which may be due to difference in foliar treatment. 19-19-19 WSF @ 0.5 % sprayed treatments had lowest ADF and NDF content and so possess better quality. Results show foliar spray of 19-19-19 WSF most successful in respect of growth performance and ADF/ NDF content in all the six crops.
