ThesisItem Open Access INFLUENCE OF MULCHING MATERIALS, BIOCHAR AND BIOSTIMULANTS ON MICROMETEOROLOGICAL PARAMETERS, GROWTH AND YIELD OF TOMATO(Keladi Shivappa Nayaka University Agricultural and Horticultural Science (COA,Shivamogga), 2023-08-23) ASHWINI AMBADI; Dr. S. SRIDHARA; Dr. N. S. MAVARKARField experiments were conducted at the College of Agriculture, KSNUAHS, Shivamogga during the kharif 2020 and 2021 on red sandy clay loam soil on the influence of mulching materials, biochar and biostimulants on micrometeorological parameters, growth and yield of tomato. The experiment-I was laid out in RCBD with a factorial concept involving four mulching materials viz., Pongamia leaves @ 4 t ha-1, Polythene mulch, Paddy straw @ 10 t ha-1 and no mulch with three biostimulants namely Nano nitrogen @ 4 ml lit-1, Brassinolide @ 5 ml lit-1 and Control. Among the different mulching materials, paddy straw @ 10 t ha-1 recorded significantly higher plant height (158.91 cm), yield (81.36 t ha-1) and quality parameters as compared to other mulching materials. Among the biostimulants, brassinolide @ 5 ml lit-1 recorded higher plant height (157.67 cm), yield (78.36 t ha-1) and quality parameters as compared to other biostimulants. The experiment-II was laid out in RCBD with a factorial concept involving five biochars viz., Biochar 1 @ 5 t ha-1, Biochar 2 @ 5 t ha-1, BC1+ FYM (2.5 t ha-1 + 5 t ha-1), BC2 + FYM (2.5 t ha-1 + 5 t ha-1) and FYM @ 10 t ha-1 and with three biostimulants namely Humetus @ 5 ml lit-1, Brassinolide @ 5 ml lit-1 and Control. Among the different biochars, biochar 2 @ 5 t ha-1 recorded significantly higher plant height (129.47 cm), yield (71.56 t ha-1) and quality parameters as compared to other biochar. Among the biostimulants, brassinolide @ 5 ml lit-1 recorded higher plant height (128.53 cm), yield (73.89 t ha-1) and quality parameters compared to other biostimulants.ThesisItem Open Access STUDIES ON COMPOST PREPARATION WITH VARIED CROP RESIDUES AND GREEN BIOMASS PROPORTIONS AND ITS EVALUATION IN ORGANIC PRODUCTION OF RABI SORGHUM (Sorghum bicolor L.)(UNIVERSITY OF AGRICULTURAL SCIENCES, RAICHUR, 2016-09-30) ASHWINI AMBADI; KRISHNAMURTHY, DA field experiment was conducted on vertisols at Organic Farming Research Institute Farm, UAS, Raichur during rabi 2015 after preparation different composts comprising crop residues and Glyricidia combinations. Which was laid out in Randomized Complete Block Design with fifteen treatments of which twelve treatments were based on recommended nitrogen supply through different composts, recommended FYM (3 t ha-1) + RDF (50:25 N:P2O5 kg ha-1), RDF (50:25 N:P2O5 kg ha-1) and absolute control with three replications. The results of compost experiment revealed that significantly higher nutrient content (2.35, 0.58 and 1.28 % NPK, respectively), per cent reduction in biomass (64.5%), height (88.4%) and microbial biomass viz. Bacteria (17.00 X 107 CFU g-1 of compost), Fungi (18.67 X 104 CFU g-1 of compost) and Actinomycetes (10.00 X 103 CFU g-1 of compost) was recorded with Cotton stalks + Redgram stalks + Glyricidia sp. with initial C:N of 30:1 over other treatments and it was on par with Redgram stalks + Glyricidia sp. with initial C:N of 30:1, Glyricidia sp. with initial C:N of 22:1, Cotton stalks + Glyricidia sp. with initial C:N of 30:1. Significantly higher nitrogen, phosphorous and potassium uptake by rabi sorghum (227.3, 75.7 and 141.7 kg ha-1, respectively), higher grain yield (39.7 q ha-1), stover yield (13.2 t ha-1) and B:C (3.08) was recorded with application of FYM @ 3 t ha-1 + RDF (50:25 N:P2O5 kg ha-1) followed by Cotton stalks + Redgram stalks + Glyricidia sp. with C: N of 30:1 compost @ 50 kg N equivalent (222.0, 74.0 and 132.3 kg ha-1, 36.6 q ha-1, 12.9 t ha-1 and 2.90). The least uptake (127.0, 42.0 and 71.7 kg ha-1) and lowest grain yield (18.4 q ha-1) was recorded with absolute controlThesisItem Open Access STUDIES ON COMPOST PREPARATION WITH VARIED CROP RESIDUES AND GREEN BIOMASS PROPORTIONS AND ITS EVALUATION IN ORGANIC PRODUCTION OF RABI SORGHUM (Sorghum bicolor L.)(UNIVERSITY OF AGRICULTURAL SCIENCES, RAICHUR, 2016-09-30) ASHWINI AMBADI; KRISHNAMURTHY, DA field experiment was conducted on vertisols at Organic Farming Research Institute Farm, UAS, Raichur during rabi 2015 after preparation different composts comprising crop residues and Glyricidia combinations.
