EFFECT OF ORGANIC FERTILISERS ON GROWTH, YIELD AND QUALITY OF TOMATO Table 1. Salient characteristics of organic fertilisers S.

Data set out in the Table revealed significant difference in plant height due to the application of various treatments. The plant height at vegetative stage was recorded highest by T 3 (Inorganic NPK and Zn) and at 90DAT by T 6 (Inorganic N + Bio Phos + Bio Potash + Bio Zinc). Combination of organic inputs along with inorganics also increased the plant height significantly over organics alone. Similar benefits with organic fertilizers were reported in green gram crop by Anuradha (2010). Supply of P, K through organic fertilizers (T 6 ) resulted in increase of plant height by 14.1 cm i.e., 32% over Inorganic P K (T 3 ). And also it was observed that supply of zinc through Bio Zinc recorded higher values by 7.8% compared to that when supplied through inorganic ZnSO 4. This could be due to the nutrient composition of the organic fertilizers viz., Bio Phos, Bio Potash, Bio Zinc, New Suryamin and Aishwarya which contained organic carbon, nitrogen and zinc besides their main nutrient. Makinde (2007) reported highest maize plant height of 111 cm with organo mineral fertilizer which was 44 % more than the control plot. Drymatter production was significantly higher compared to control in both the stages of crop growth. Plant dry matter production is a result of Growth Environment interaction through leaves, stems, roots and reproductive parts which contribute to dry matter. Highest dry matter was produced with integrated approach of application of nutrients as in T 10 (Aishwarya + Inorganic NPK) at 30DAT and in T 6 (Inorganic N + Bio Phos + Bio Potash + Bio Zinc) at 90 DAT, which recorded 11.8 g higher dry matter when compared to T 3 (Inorganic NPK and Zn ). Marimuthu et al. (2003) recorded the highest growth of green gram by the application of 25 Kg P 2 O 5 ha -1 as Mussorie rock phosphate along with enriched biodigested slurry. Leaf area recorded at vegetative stage (30 DAT) presented in Table 2 showed significant 127
