초록
A field experiment to evaluate the effect of application of different organic manures and inorganic fertilizers on growth, yield and quality of leaf was studied during 2004-05 has showed that, the application of 10 kg each of Azospirillum brasilense and Aspergillus awamori+ 20% each of recommended N through compost+ green manure (Glyricidia maculata)+castor cake+ vermicompost+Urea and remaining P and K through fertilizers (T11) has recorded significantly higher leaf yield (250 g/ plant and 34.70 tonnes/ha/yr, respectively) with improvement in growth characters as compared to control. Leaf quality status was also improved in terms of N (3.19%), P (1.97%), K (1.28%), total soluble protein (8.39 mg/ml), total soluble sugars (14.40 mg/ml), secondary nutrients viz., Ca (3.00%), Mg (0.60%), S (0.35%) and micronutrients viz., Cu (0.410 ppm), Mn (0.454 ppm) and Zn (0.112 ppm) contents. The mulberry grown with 20 tonnes of compost+300:120:120 Kg of NPK/ha/year through fertilizer ranked second for growth and foliar constituents.
