Abstract

Casing soil formulations were prepared from farm yard manure, garden soil and sand with different combinations which were chemically sterilised and used for casing the mushroom bags of Calocybe indica. In the present study, out of various casing material combinations FYM: Garden soil :Sand (2:1:1) having pH (8) and 3 cm width were found suitable and showed best result in yield as well as biological efficiency.

Abstract

In cultivation of button mushroom [Agaricus bisporus (Lange) Imbach], casing layer that is nutritionally deficient to compost is believed to trigger the fruit body formation and this is conducted by the bacterial community residing in casing layer. Therefore, relationship between different concentrations (1 x 104, 1 x 106, 1 x 108, 1 x 1010, 1 x 1012) of bacterial inoculants (Pseudomonas putida) and yield of Agaricus bisporus were determined. Available data showed a significant difference in yield in respect to concentration of bacterial inoculant added. In addition, concentration 1x 108cfu/ml was found to be high yielding concentration, which took minimum case run period together with higher biological efficiency compared to other.

Abstract

An experiment was conducted to evaluate the effect of bio agents (Trichoderma harzianum and Pseudomonas fluorescens) and fungicides (mancozeb) against earlyblight of tomato caused by Alternaria solani (Ell. and Mart.) at the experimental field of Department of Plant Protection, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Allahabad during Rabi Season (2013-2014). Seven treatments including control with three replications were taken up using RBD. The treatments comprised of seed treatment and foliar spray (once and twice) of bio-agents Trichoderma harzianum and Pseudomonas fluorescens while fungicide taken up was mancozeband Control (spray of plain water) was applied. Observation for percent disease intensity was recorded at 70, 90 and 105 days after transplanting. Minimum disease intensity was recorded in mancozeb with twofoliar spray (15.43%, 17.90% and 20.47%, respectively) as compared to control which recorded maximum disease intensity (25.50%, 33.47%, and 48.73%, respectively).The bio agents Trichoderma harzianum and Pseudomonas fluorescens (seed treatment + two foliar spray) were also effective in reducing the disease intensity.

Abstract

An experiment was conducted to evaluate the effect of bio agents (Trichoderma harzianum and Pseudomonas fluorescens) and fungicides (mancozeb) against early blight of potato caused by Alternariasolani (Ell. and Mart.) at the experimental field of Department of Plant Protection, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Allahabad during Rabi Season of 2013-2014. Seven treatment including control with three replications were taken up using RBD. The treatments comprised of seed treatment and foliar spray (once and twice) of bio agents Trichoderma harzianum and Pseudomonas fluorescens while fungicide taken up was mancozeb and control (spray of plain water) was applied. Observation for per cent disease intensity was recorded at 60 and 80 days after sowing. Lowest disease intensity was recorded in mancozeb (15.07% and 18.40%, respectively) as compared to control which recorded highest disease intensity (20.91% and 33.80%, respectively).Mancozeb not only reduced disease intensity but also recorded highest yield (253.00 q/ha) as compared to control which recorded 157.83 q/ha.The bio agents Trichoderma harzianum and Pseudomonas fluorescens (seed treatment +foliar spray) were also effective in reducing the disease intensity and increasing tuber yield.
