Effect of growth substances on morpho-physiological traits and yield in pearl millet under rainfed condition

Abstract

Field experiment was carried out to find out the effect of foliar spray of plant growth retardant substances on different growth parameter of pearl millet under rainfed condition during kharif 2015-17. The results revealed that foliar application of growth regulating substances had significant impact on number of effective tillers, plant height and chlorophyll content. Plant height and chlorophyll content at 70 days after sowing were significantly affected with application of growth regulating substances in all individual years as well as in pool analysis. Results indicated that foliar application of potassium chloride 1.50 per cent at 30-35 days after sowing (tillering stage) and 50-55 days after sowing (post-anthesis stage) for proper vegetative growth and to get higher seed yield and net return. The results also indicated that net return (Rs. 27245 /ha) was maximum with foliar application of potassium chloride 1.50% at tillering and post-anthesis stage along with B:C ratio 1.16.

Assessment of integrated management technologies in Bt-cotton under drip irrigation

“…Seed cotton yield was influenced significantly due to various treatments and highest seed cotton yield was recorded in T 8 (Polythene mulch + Removal of Monopodia at 60 DAS + Detopping at 75 DAS) (3314, 3911 and 3613 kg ha -1 during 2021-22, 2022-23 and in pooled respectively) and it was significantly superior over rest of the treatments. Similar results were observed by Choudhary et al (2021) [2] , Vekaria et al, (2020) [3] , Suma et al, (2019) [6] , Isal et al, (2019) [7] and Chauhan et al, (2014) [10] . [2] and Jayswal et al, (2022) [9] .…”

“…Data on yield attributing characters such as number of bolls plant -1 , boll weight (g) and yield plant (g) are presented in Table 02 [2] , Vekaria et al, (2020) [3] , Suma et al, (2019) [6] and Chauhan et al, (2014) [10] .…”

Minimizing the Effect of Low Moisture Stress in Pearl Millet (Pennisetum glaucum L.) by Regulating Growth, Yield and Antioxidant Defense System Via Foliar Applied Silicon

“…Flowering stage is a critical growth stage where impact of drought stress was too high [34]. A huge yield gap was observed when crop was exposed to low moisture stress at flowering initiation stage [35]. The raining period start and end during the vegetative stage, that's way drought stress mostly occurs at reproductive stage.…”

Research Progress in Soybean by Phytohormone Modulation and Metal Chelation over the Past Decade

“…The detrimental effects of heavy metal toxicity on ecosystems, crops, and human health have become a global concern, affecting millions of hectares of cultivable land worldwide [5]. Heavy metal (HM) stress, categorized as an abiotic stress, presents a persistent challenge to agricultural practices and significantly reduces the yield of vital crops, such as rice [6], maize [7], millet [8], wheat [9], and soybean [10]. HMs are characterized by their high density, with a density exceeding 5 g/cm 3 , and they possess relatively higher osmotic weight.…”
