Artificial infestation of Sesamia inferens larvae at 2 leaf stage (7 DAE) of the crop growth (Table 1) recorded significantly lowest mean grain yield of 47.59 q ha-1 than infested at 4 (53.44 q ha-1), 6 (59.84 q ha-1) and 8 (67.34 q ha-1) leaf stage of the crop. Artificial infestation of the maize crop with different larval densities (0, 5, 10, 15 and 20 larvae per plant) (Table 2) indicated that release of 20 larvae per plant adversely affected the grain yield and recorded 49.97 q ha-1 which was significantly less than the grain yield obtained with 15 larval density (54.12 q ha-1) and 10 larval density per plant (57.32 q ha-1). Estimation of avoidable yield losses in maize crop against S. inferens (Table 3) indicated that among the different stages of the crop growth, 2 leaf stage of the crop protected with endosulfan recorded maximum avoidable yield loss with different larval densities (18.17%, 22.45%, 35.12%, 37.62% and 45.39% with 0, 5, 10, 15 and 20 larval density per plant, respectively), than the other stages of crop and hence spraying of endosulfan at early stages of crop growth was found highly effective for controlling S. inferens and for obtaining higher yields.Keywords

The varietal screening studies of ten maize genotypes were carried out under field conditions with artificial infestation of Sesamia inferens and the classification of the maize genotypes was done based on the dead hearts and leaf injury rating. Among the ten maize genotypes, Madhuri (5.03) was classified as highly resistant genotype, while BML 7 (5.33) was placed under resistant category. The genotype, HKI 163 (5.87) was classified as moderately resistant genotype. The remaining five genotypes viz., HQPM 1 (6.50), MP 717 (6.93), BML 6 (7.03), BH 40625 and BH 1576 (7.90) were grouped as highly susceptible.Keywords

The present investigation was carried out to study the marketing behaviour of groundnut farmers in Anantapuramu district of Andhra Pradesh. Ex-post facto research design was followed for the study and a sample of 120 respondents were drawn. The results of the study revealed that 67.50 per cent of the groundnut farmers had medium marketing behaviour followed by high (18.33%) and low (14.16%) levels of marketing behaviour with medium planning orientation (79.16%), medium production orientation (79.16%), medium marketing orientation (69.16%), medium marketing information sources utilization (74.17%), medium decision making ability (70.83%), medium risk taking ability (68.33%).Keywords
