Evaluation and Performance of Integrated Crop Management in Chilli in Rainfed Tracts of Prakasam District, Andhra Pradesh, India

Chilli is an important high value spice crop, its integrated crop management is an important area for the welfare andlivelihood security of farmers. Most of the farmers of Prakasam district of Andhra Pradesh are growing wide varieties and cultivars of chilli but so far the research findings on chilli integrated crop management were less aware. To know the yield potential of integrated crop management and its economic impact, evaluation on integrated crop management was conducted at Chandhaluru and Nallaguntla Guedm villages. The adopted package of practices was seed rate @1kg/ha, spacing 60x45cm, FYM 15t/ha, Urea, single super and muriate of potash256:150:80 kg/acre. There was wide variation between integrated crop management and farmers practice in fruit yield and economic returns. The results on yield and economic returns indicated that chilli integrated crop management was found superior to farmers practice. Integrated crop management could obtain 124 fruits per plant and yield of 47.00q/ha, thirps incidence (24.3%), whitefly incidence (9.67 %) and fruit rot infestation (6.0%). Whereas,in farmers practicefruits obtained were99per plant and yield of 43.00q/ha, thripsincidence (44.67 %),whiteflyincidence (28.33) and fruit rot(18 %) with a net income of Rs220000/- and B:C ratio 1: 1.88 compared to farmers practice with a net income of Rs113333/-with B:C ratio 1:1.36. The integrated crop management percent yield increased over farmers practices8.5 per cent. It was concluded that integrated crop management could help to improve the economy of the farmers.

RP-HPLC method for the estimation of nitroxazepine hydrochloride in pharmaceutical dosage forms.

A simple and sensitive isocratic RP‐HPLC method was developed for the determination of Nitroxazepine hydrochloride in bulk drug and its pharmaceutical tablet formulations where the mobile phase optimized was Phosphate buffer : Acetonitrile (70:30) and Phenomenex C18 column (250 mm length, 4.6 mm internal diameter and particle size 5 μm) was used as the stationary phase. The flow rate and detection wavelength was 1.0 mL min‐1 and 265 nm respectively. The developed method was validated as per ICH guidelines for specificity, linearity and range, precision, accuracy, robustness, limit of quantification and limit of detection. The results of all the validation parameters were well within their acceptance values. The method gave good recovery in the range of 98.95‐99.43 % for Nitroxazepine hydrochloride when it was applied for its determination in pharmaceutical tablet formulations.
