Evaluation of chrysanthemum (Dendranthema grandifloraTzvelev) varieties in southern zone of Andhra Pradesh

The 3 oyster mushroom species namely Pleurotus florida, P. eous, and Hypsizygus ulmarius were evaluated for their biological efficiency (BE) and net returns from the rupee invested (NRRI) in late kharif and rabi seasons. The BE and NRRI of P. florida and H. ulmarius were on par and significantly superior to P. eous in both the seasons. The present study provided corroboration for the suitability of P. florida and H. ulmarius cultivation in the late kharif and rabi seasons whereas, P. eous cultivation in the summer and early kharif seasons. Thus, the season-specific selection of oyster mushroom species promotes the concept of year-round mushroom cultivation.

Aims: To study the effect of zinc fertilization through soil and foliar at different stages of finger millet on yield, yield attributes and quality in two major finger millet varieties under rainfed alfisols of southern zone, Andhra Pradesh Study Design: Split-plot design Place and Duration of Study: Wetland farm, S.V Agricultural College, Tirupati and during kharif season of 2019 and 2020 (Two seasons) Methodology: Zinc fertilization to two major finger millet varieties viz., Vakula and Tirumala through soil and foliar application at different crop stages with following treatments viz., Control (No fertilizers and manures); RDF (60 -30-20 kg N-P-K + FYM @ 4 t ha-1); RDF + soil application of ZnSO4 @ 25 kg ha-1 as basal; RDF+Soil application of chelated-ZnSO4 @ 5 kg ha-1; RDF+foliar application of 0.2% ZnSO4 at ear head emergence stage; RDF+foliar application of 0.2% ZnSO4 at grain filling stage; and RDF+foliar application of 0.2% ZnSO4 at ear head emergence and grain filling stage. The yield, yield attributes and quality parameters viz., protein, zinc and iron content in grains were determined by adopting standard protocols. Results: The application of zinc significantly (p<0.05) improved the yield and quality parameters over control. The foliar application of 0.2% ZnSO4 at ear head emergence and grain filling stage was significantly (p≤0.05) improved the yield and yield attributes of finger millet over RDF. The grain yield, straw yield, no. of productive tillers per plant, no. of fingers per plant were increased to 57.0%, 83.2%, 44.6% and 51.7%, respectively over RDF i.e., 60-30-20 kg N-P-K + FYM @ 4 t ha-1. The quality parameters namely protein, grain zinc and iron also increased up to 40.7%, 69.5% and 43.2%, respectively over RDF. Conclusion: Application of zinc sulphate at ear head emergence and grain filling stages enhanced the yield, yield parameters and quality parameters compared to other treatments of tirumala variety under rainfed alfisols of southern zone of Andhra Pradesh.

An investigation was carried out to study different forms of phosphorus under major cropping systems in Y.S.R. Kadapa district of Southern Zone of Andhra Pradesh. Five soil samples from each cropping system at 0-15 cm depth collected from each cropping system to study their physicochemical properties, status of available P2O5 and different forms of P. Majority of the soils were moderately alkaline in reaction, non-saline, free lime content indicating that these soils are moderately calcareous, medium to high in available P2O5. Highest mean values for available P2O5 (182.41 kg ha-1), Al-P (80.82 mg kg-1), Ca-P (118.55 mg kg-1) and total-P (434.35 mg kg-1) were recorded in groundnut monocropping system whereas for saloid P (23.01 mg kg-1), Fe-P (69.82 mg kg-1) and other forms of P (228.35 mg kg-1) highest mean values were recorded under sunflower-sesame, groundnut-groundnut and fallow-bengal gram cropping systems, respectively.
