The experiment was laid out in Randomized Complete Block Design (Factorial) with three replications comprising of twelve treatment combinations. The treatments were G0J0: No Ghanjeevamrit + No Jeevamrit (control), G0J1: No Ghanjeevamrit + Jeevamrit spray @ 10 %, G0J2: No Ghanjeevamrit + Jeevamrit spray @ 15 %, G0J3: No Ghanjeevamrit + Jeevamrit spray @ 20 %, G1J0: Ghanjeevamrit @ 1 t/ha + No Jeevamrit, G1J1: Ghanjeevamrit @ 1 t/ha + Jeevamrit spray @ 10 %, G1J2: Ghanjeevamrit @ 1 t/ha + Jeevamrit spray @ 15 %, G1J3: Ghanjeevamrit @ 1 t/ha + Jeevamrit spray @ 20 %, G2J0: Ghanjeevamrit @ 1.5 t/ha + No Jeevamrit, G2J1: Ghanjeevamrit @ 1.5 t/ha + Jeevamrit spray @ 10 %, G2J2 :Ghanjeevamrit @ 1.5 t/ha + Jeevamrit spray @ 15 %, G2J3: Ghanjeevamrit @ 1.5 t/ha + Jeevamrit spray @ 20 %. The main crop (tomato) variety was ‘Solan Lalima’. The intercrops were French bean cv. ‘Contender’ and brinjal cv. ‘Pusa Purple Long’. Each plot size was 5.4 m2 having five rows of tomato at the spacing of 90 × 30 cm and four rows of intercrops were also sown in the centre of tomato crop. The seeds of tomato and brinjal were sown in the nursery beds on 3rd March, 2023 and the seedlings were transplanted on 15th April, 2023.The seeds of French bean was shown after 2 days of transplanting of main crop. The combined application of ghanjeevamrit @ 1.5t/ha along with jeevamrit spray @ 15 per cent (G2J2) resulted in maximum plant height, harvest duration, number of fruits per cluster, number of fruits per plant, fruit yield per plant, yield per plot and per hectare, organic carbon, NPK content, viable microbial count and highest net returns. Hence, application of ghanjeevamrit @ 1.5 t/ha + jeevamrit spray @ 15 per cent at 15 days interval can be recommended for getting high yield, enhanced soil fertility and maximum net returns in tomato under natural farming condition.EnglishThesis
