Effect of Certain Fungicides and Trichoderma Spp. on the Growth Parameter, Yield Attributes and Yield Affected by Powdery Mildew of Green Gram (Vigna radiata L.)

Abstract

Powdery mildew is an important foliar disease of green gram caused by Erysiphe polygoni DC. in India. An experiment was carried out to evaluate the efficacy of fungicides (Propiconazole, Carbendazim, Wettable sulphur, Mancozeb) and bio-agents (Trichoderma viride, T. harzianum,) against powdery mildew of green gram in the Central Experimental Field, Department of Plant Pathology, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during the kharif season 2018-19. The experiment was laid out in Randomized Block Design (RBD) with seven treatments and each replicated thrice. In a field assay, maximum plant height (71.11) cm was observed in Trichoderma viride as foliar spray followed by Trichoderma harzianum, Carbendazim, Wettable sulphur, Propiconazole and Mancozeb. The experiment revealed that, among the treatments Carbendazim, as foliar spray was most effective with maximum length of pods (7.27) cm and weight of pods (5.6) g followed by Wettable sulphur, Propiconazole, Mancozeb, Trichoderma harzianum and Trichoderma viride. Maximum yield was recorded with Carbendazim (10.15) q/ha, as foliar spray followed by Wettable sulphur (9.76) q/ha, Propiconazole (9.22) q/ha, Mancozeb (8.60) q/ha, Trichoderma harzianum (7.88) q/ha and Trichoderma viride (7.22) q/ha.

Effect of sulphur and iron on growth, yield and quality of chickpea

“…The iron is essential for plant functions such as, chlorophyll development, energy transfer within the plant, acts as a constituent of enzymes and proteins and also for plant respiration and plant metabolism which improves photosynthesis, therefore helps to increase in number of pods in chickpea. This result collaborates with the findings of Meena et al (2013) [11] and Gahlot et al (2020) [4] . [14] and Kuldeep et al (2018) [9] .…”

“…The increase in yield of chickpea might be due to better availability of available nutrients in the soil and higher uptake of nutrients by plant which ultimately led to effective assimilate partitioning of photosynthesis from sources to sink in post-flowering stage. This result collaborates with the findings of Meena et al (2013) [11] and Ray et al (2015) [15] . The crude protein (20.67%) in chickpea seed was found significantly higher with the treatment of application of 30 kg S/ha (S30) and was found to be at par with treatment of application of 20 and 10 kg S/ha (S20 and S10, respectively).…”

Effect of integrated nutrient management on yield and quality parameter of wheat (Triticum aestivum): Summer green gram (Vigna radiata L.) cropping sequence in middle Gujarat condition

“…The increased green gram seed yield might be due to addition of FYM to preceding crop resulting in improvement in soil structure which reduced the soil crusting and also serves as a source of energy for soil microflora which resulted in better root nodulation and nitrogen fixation. It is confirmed by Meena et al (2012) [7] and Singh (2016) [11] . 879 889 884 2062 1995 2028 T3: 120:60:00 NP kg ha -1 (RDF) + FYM @ 10 t ha -1 955 961 958 2234 2174 2204 T4: 120:60:00 NP kg ha -1 (RDF) + FYM @ 5 t ha -1 + NPK consortium 1138 1152 1145 2623 2592 2607 T5: 120:60:00 NP kg ha -1 (RDF) + FYM @ 5 t ha -1 + NPK consortium + Sulphur @ 20 kg ha -1 (gypsum) + 10 kg ha -1 ZnSO4 1201 1230 1215 2756 2714 2735 T6: 90:45:40 NPK kg ha -1 + FYM @ 1.5 t ha -1 479 508 494 1157 1158 1158 T7: 90:45:00 NP kg ha -1 + FYM @ 2.5 t ha -1 527 544 535 1270 1284 1277 T8: 90:45:00 NP kg ha -1 + FYM @ 10 t ha -1 624 625 625 1481 1464 1473 T9: 90:45:00 NP kg ha -1 + FYM @ 5 t ha -1 + NPK consortium 578 576 577 1386 1297 1341 T10: 90:45:00 NP kg ha -1 + FYM @ 5 t ha -1 + NPK consortium + Sulphur @ 20 kg ha -1 (gypsum) + 10 kg ha…”

“…globosum and S. cerevisiae alone or formulated on rice straw and bagas effectively reduced powdery mildew compared to other treatments and control. Deore et al (2004) used culture filtrates of different species of Trichoderma for the management of powdery mildew of cluster bean caused by Leveillula tau rica. They revealed that culture filtrates of Trichoder ma spp.…”
