Rice blast caused by Pyricularia oryzae is one of the major destructive diseases of rice growing regions of the world including India. It causes yield loss up to 80 per cent (Ou, 1985) but normally can lead to 30 per cent yield loss annually (Talbot, 2003). P. oryzae is a hemi biotrophic pathogen, initially grow […]
ABSTRACT Ten genotypes of pigeonpea viz., ICPL 20338, ICPL 11255, ICPL 20325, ICPL 88039 (super early genotypes) and AKTE 12-04, WRG 121, TRG 111, KRG 33, WRG 93, PRG 176 (mid early genotypes) were grown on the sandy loam soils of dryland farm, S.V. Agricultural College, ANGRAU, Tirupati in late kharif, 2019-20. The pigeonpea genotypes […]
ABSTRACT An investigation was carried out during 2019-2020 to characterize and study the seasonal changes in the composition of sewage water used for irrigating rice fields in Pathakadapa area of YSR district. Results depicted certain seasonal variations in physico-chemical characteristics of sewage water. Effluents collected in different time intervals were dark in colour with appreciable […]
ABSTRACT Thirty three genotypes of peanut were evaluated during kharif 2019 to estimate genetic parameters viz., genetic variance, heritability (broad sense) and genetic advance as per cent of mean for 19 characters. The analysis of variance revealed that highly significant differences were observed among the genotypes for all the characters studied except dry haulms yield […]
ABSTRACT A field experiment was conducted during kharif, 2019 on sandy loam soils of Wetland farm of S.V. Agricultural College, Tirupati campus of Acharya N.G. Ranga Agricultural University. The results of the experiment revealed that intercropping system of maize + cowpea in 3:1 ratio recorded significantly higher total green fodder and dry fodder yield. Quality […]
ABSTRACT An experiment was carried to evaluate the performance of eighteen pigeonpea genotypes under drought stress. Drought stress was imposed at two phenophases of growth such as flowering and pod maturation stages. The parameters such as Chlorophyll a, b, a : b ratio, soluble protein, leaf epicuticular wax (ECW) and yield were recorded at flowering […]
ABSTRACT Forecasting models were helpful for managing and decision making in planning for the future effectively. This paper attempted forecasting univariate time series of banana production in India, the proposed Auto Regressive Integrated Moving Average (ARIMA) algorithm appears more powerful than traditional models. Used 69 years data banana production (1951-2019) in India and applied time […]

ABSTRACT A field experiment was conducted during kharif, 2019 on sandy loam soils of dryland farm of S.V. Agricultural College, Tirupati campus of Acharya N.G. Ranga Agricultural University. The experiment was […]
ABSTRACT Field experiment was conducted during kharif 2017 and 2018 at Tirupati, Andhra Pradesh to evaluate the effect of organic manures and phosphorus levels on growth, yield and economics of vegetable cowpea. Three levels of organic manures (no organic manure, FYM @ 5 tonnes ha-1 and poultry manure @2 tonnes ha-1) and 3 phosphorus levels […]
