Response of bio-regulators to morphology and yield of clusterbean [Cyamopsis tetragonoloba (L.) Taub.] under different sowing environments

Abstract

An experiment was conducted during kharif season of 2014, aims of the experiment were to investigate suitable sowing environment and bio-regulator and its effect on clusterbean (Cyamopsis tetragonoloba (L.) Taub.), experimental treatments were applied foliar spray of thiourea (500, 1000 ppm) and salicylic acid (50, 100 ppm) at 45 and 60 days after sowing under normal (15 July) and late (30 July) sowing environments. Normal sowing performed well as compared to late sowing, in respect to all morphology and yield parameters. Amongst foliar spray, significantly higher plant height (100.17 cm), number of branches per plant (7.99), leaf area index (4.85), seed yield (9.19 q/ha) and harvest index (29.39) were recorded in foliar spray of thiourea 500 ppm as compared to all other bio-regulators spray level. Similarly, salicylic acid 100 ppm found statistically at par with thiourea 500 ppm foliar spray at 45 and 60 DAS. Impacts of climate change have significant reflections on clusterbean productivity. Sowing dates plays a vital role to determining the productivity of clusterbean with bio-regulators spray by controlling the environmental factors.

Influence of organic and inorganic sources of nutrients on growth, yield and quality of mungbean (Vigna radiata)

“…Vermicompost increases the supply of all essential plant nutrients for the growth and development of plants. These results are in agreement with Tak (2003) and Meena et al (2016). It is also indicated from the Table 1 that the application of 125% RDF +Zn +Fe produced significantly highest plant height (51.76 cm) and DMA (15.32 g/plant) at harvest, LAI (3.76), number of trifoliate leaves (12.33) and chlorophyll content (44.42 SPAD value) at 45 DAS, while, it was statistically at par with the application of 100% RDF +Zn +Fe.…”

Growth, yield and quality of cluster bean (Cyamopsis tetragonoloba) as influenced by integrated nutrient management under alley cropping system

“…The beneficial effect of pressmud+ Rhizobium in growth attribute was probably due to enhanced supply of macro as well as micronutrients during the growing season. This study was supported by Rajkhowa et al (2002), Jamil et al (2004), Meena et al (2016).…”

Effects of Abiotic Stress on Soil Microbiome

“…Other herbicides, when combined with heavy metals and inorganic fertilizers, decreased soil microbial functions [295,296]. Herbicides individually or in combination may disrupt the symbiotic relationship involving rhizobacteria and plants (legumes), preventing critical N 2 -fixation activities [297][298][299][300]. Herbicide application on legumes can alter nodulation and, consequently biological nitrogen fixation (BNF) through disrupting the infestation of rhizobacterial or disrupting the plant's root tissues where infestation and node production takes place.…”
