RÉSUMÉ
The field experiment was conducted during Rabi season of, 2022–2023 on sandy clay loam soils at a dry land farm in the S.V. Agricultural College in Tirupati, Andhra Pradesh, India. To study the Effect of organic nutrient management on quality parameters and yield of fodder cowpea The Split-plot design of the study included three replications. The treatments consisted of four varieties viz., V1: Vijaya, V2: MFC-09-01, V3: MFC-09-03, and V4: MFC-08-14 assigned to main plots, four organic nutrient management practices viz., F1: Control, F2 : 100 % organic source through (FYM) F3: 75 % organic source through (FYM) + Rhizobium + PSB + KSB and F4: 50 % organic source through (FYM) + Rhizobium + PSB + KSB allotted to sub plots. The soil was neutral in reaction (6.8 pH) low in available nitrogen (176 kg ha-1) and medium in available phosphorus (27 kg ha-1) and low in available potassium (219 kg ha-1) status.). The results revealed that among the varieties tested, higher quality parameters i.e., (Crude protein content , Total ash content and dry fodder yield) was recorded with MFC-09-01 (V2) and dry fodder yield (5.8 t ha-1) as well as crude protein (15.1 %), ash content (12.5 % ) were obtained with the application of 75 % organic source through (FYM) + Rhizobium + PSB + KSB. Furthermore, compared to all other treatments.
RÉSUMÉ
The field experiment was conducted during Rabi season of 2022 on sandy clay loam soils at wetland farm of the S.V. Agricultural College, Tirupati, Andhra Pradesh, India, to study the effect of liquid biofertilizers on productivity, quality, and soil biota of fodder sorghum. The treatments were allocated in randomized block design and replicated thrice. The soil was neutral in reaction (6.9 pH), low in available nitrogen (115 kg ha-1), medium in available phosphorus (29 kg ha-1) and low in available potassium (156 kg ha-1) status. The initial soil contains bacteria (13.08 X 107 CFU g-1 soil), fungi (4.04 X 104 CFU g-1 soil) and actinomycetes (1.54 X 103 CFU g-1 soil). The results revealed that the maximum green (32.1 t ha-1) and dry (13.0 t ha-1) fodder yield as well as crude protein (7.3%) were obtained with the application of 75% RDF + Azospirillum + PSB + KSB (Both seed & soil application). Furthermore, this treatment produced a significantly higher soil bacterial (23.2 X 107 CFU g-1 soil), fungal (13.7 X 104 CFU g-1 soil) and actinomycetes (10.3 X 103 CFU g-1 soil) population at harvest.
