    Role of organic manures in combination with inorganic fertilizer in tomato production cv Hisar Arun
    (CCSHAU, 2007) Rajesh Kumar; Batra, B.K.
    The present investigation entitled Role of organic manures in combination with inorganic fertilizers in tomato production Cv. Hisar Arun was conducted during spring summer Season of 2006-07 at Vegetable Research farm and Laboratory of CCS Haryana Agricultural University Hisar to find out the effect of organic manures and inorganic fertilizers on growth yield and quality of tomato. The experiment was laid out in a Randomized block design in tree replication having thirteen treatments. The observations were recorded on Vegetative growth flowering, yield and fruit quality. Each treatment and replicated three times in plot having area 3 x 2.7 m2. The results indicated that organic manures and inorganic fertilizer was marked effect on growth and yield parameters. The yield attributing characters like number of fruits/ plant, Average fruit weight, yield /plant and yield (q/ha). Were maximum with the application of 17.5t FYM +50% RDF. Among the quality parameters like pericarp thickness, lycopene, total soluble solids, ascorbic acid (mg/100%), acidity (%) were also significant influenced by the combination of organic manures and inorganic fertilizers

    Studies on powdery mildew of fenugreek caused by erysiphe polygoni DC
    (CCSHAU, 2009) Rajesh Kumar; Mehra, Rakesh
    The Studies on powdery mildew of fenugreek caused by Erysiphe polygoni DC" were conducted in the Departments of Plant Pathology and Vegetable Science, CCS Haryana Agricultural University, Hisar during winter (rabi) season of 2008-09. The experiments were laid out in RBD in field and CRD in lab conditions. Powdery mildew of fenugreek generally occurs during flowering and pod formation stage in severe form. Seed yield losses due to powdery mildew varied between 18.8 and 20.4 per cent in variety Hisar Sonali and 19.4-22.5 per cent in variety Hisar Suvarna in both greens cutting and non greens cutting under unprotected conditions. Out of 118 germplasm lines/varieties of fenugreek screened against powdery mildew under field and screen house conditions, none was found highly resistant. Only two genotypes namely NDM-1 and RMt-351 were found resistant under field conditions. However, under screen house conditions these genotypes were moderately resistant. Four genotypes viz., Am-187, HM-273, Local Hisar-3, NDM-9 were moderately resistant both under field and artificial inoculation conditions. Out of five dates of sowing early sown (4th October) and late sown (5th December) crop showed less disease severity as compared to 19th October, 4th November and 20th November sown crop. Maximum disease severity was in the crop sown on 4th November in Hisar Sonali, Hisar Suvarna and HM-65 varieties. Among the five varieties highest disease severity was observed in Hisar Sonali variety and lowest disease severity on variety HM-350 on all the dates of sowing. Maximum temperature range of (23.8-31.7 oC) and minimum of (7.9-14.6 oC), relative humidity morning (91.4–86.9%) and evening (53.3–38.1 %) were most congenial for the disease progression. Regression equations on relationship between disease development and weather parameters have been developed for five varieties. Among the seven plant extracts evaluated against Erysiphe polygoni, neem, ginger and garlic extracts were effective both under in vitro and in vivo conditions, however, the efficacy was comparatively less in comparison to fungicides which provided more than 95 per cent disease control. Out of eight fungicides evaluated hexaconazole, propiconazole and dinocap provided disease control around 99 per cent and also increase seed yield significantly.
