Effect of zinc levels and moisture regimes on nutrient content of direct seeded rice

Journal of Pharmacognosy and Phytochemistry (2020)

Sweeti Kumari Rahul Kumar Rajan Kumar Alisha Kumari Md. Zakir Hussain

A field experiment was conducted during rainy (kharif) season of 2017 in split plot design with three replications at Crop Research centre, Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar to investigate the “Effect of zinc levels and moisture regimes on direct seeded rice”. The treatments consisted of four moisture regimes i.e. I1-Irrigation at 1 day disappearance of ponded water, I2- Irrigation at 3 days disappearance of ponded water, I3- Irrigation at 5 days disappearance of ponded water, I4-Irrigation at 7 days disappearance of ponded and 4 zinc level treatments i.e. Z1-Control, Z2-ZnSO4 @25 kg/ha, Z3-ZnSO4@37.5kg/ha, Z4- Foliar application of ZnSO4@ 0.5% at tillering, pre-flowering and flowering. Test cultivar was Rajendra Neelam. The result showed that N, P, K and Zn content by grain and straw, were found to be maximum with I1 moisture regime which were significantly superior to I3 and I4 but was statistically at par with I2 in case of Zn content in grain and straw. N, P and K content in grain and straw were not influenced by moisture regimes. Zn content in grain and straw, were recorded maximum with Z3 treatment of zinc levels which were significantly superior over Z1 but were statistically at par with Z2 and Z4 N, P and K content in grain and straw did not vary significantly due to different zinc levels.

Root predominant overexpression of iaaM and CKX genes promotes root initiation and biomass production in citrus

Plant Cell Tissue and Organ Culture (PCTOC) (2023)

Dan Tang Yanjun Li Longmei Zhai Wei Li Rahul Kumar

Abstract Promoting initiation and biomass production of roots is significant for plant-based industries including using roots as bioreactors. Two citrus genotypes, Carrizo and US-897, were used as model plants to test the effects of root-predominantly overexpressed the iaaM (indoleacetic acid-tryptophan monooxygenase) gene and a CKX (a cytokinin oxidase/dehydrogenase) gene. The iaaM transgenic lines exhibited markedly faster root initiation, more root numbers, and higher root biomass compared to their wild-type counterparts. The transgenic iaaM + CKX plants also exhibited similar phenotypes, albeit to a lesser extent than the iaaM plants. Molecular analysis revealed an auxin-responsive CsGH3.1 gene was up-regulated in the iaaM roots and iaaM + CKX roots, and a cytokinin-responsive gene CsARR5 gene was down-regulated in the iaaM + CKX roots. Our results demonstrate that root predominant overexpression of the iaaM or both the iaaM and CKX genes drastically enhances the initiation, growth and biomass production of roots. These results provide additional support that manipulation of auxin and cytokinin levels in roots via transgenic or gene-editing technologies may benefit production of high-value secondary metabolites using roots as bioreactors and also improve rooting of recalcitrant plant species.

Enzymatic response of mungbean (Vigna radiata) genotypes against Cercospora leaf spot disease

The Indian Journal of Agricultural Sciences (2017)

Mamta Bharti Ramesh Chandra Ajay Kumar Rahul Kumar Vikas Yadav

Mungbean (Vigna radiata L.) is one of the most valuable pulse crops grown in India. Mungbean suffers from several diseases with substantial losses in yields. Among the diseases, mungbean leaf spot disease is the most destructive which is caused by Cercospora canacens and cause heavy loss (0-61%) in yield in Indian subcontinent and adjacent areas of South-East Asia. An experiment was conducted to find out the enzymatic response of various genotypes of mungbean against Cercospora leaf spot. The level of antioxidant enzyme SOD, peroxidase and catalase increase in both susceptible and resistance cultivar, but in resistance cultivar the level these enzymes increases very rapidly as compare to susceptible cultivar. Based on the various observations, it can be interprets that in resistant cultivar, the higher level of ROS produced after inoculation is minimized up to optimum level by the action of these enzymes SOD, peroxidase and catalase, but not in susceptible cultivar. Plants show resistance or susceptibility for disease is due to the activity of SOD, peroxidase, and catalase. In F2 generation plants show segregation pattern in the ratio of 1:2:1 which depicts that the gene governing the enzyme activities are partial dominant in nature.

Effect of Foliar Application of Zinc and Boron on Growth Attributes and Yield of Chickpea (Cicer arietinum L.) Varieties

International Journal of Plant & Soil Science (2023)

Rahul Kumar Binoy Kumar Saren Shriman Kumar Patel

A field experiment was conducted on loamy sandy soil during the winter season at Agricultural Farm of Palli Siksha Bhavana, Visva-Bharati, Sriniketan, Birbhum, West Bengal, India to evaluate the effect of foliar application of zinc and boron on growth attributes and yield of chickpea. In this experiment, 4 varieties of chickpea (Anuradha, ICPK, JSKB and RVSJ4-102) were applied with Zn and B ((Zinc 0.5%, Boron 0.1%, Zinc 0.5%+Boron 0.1% along with control) through foliar application at branching time and pre-flowering stage. The experiment findings revealed that the Variety RVSJ4-102 gave higher plant height (20.98cm), dry matter accumulation (114.49 g/m-2), leaf area index (1.27), chlorophyll content (2.25 mg/g fresh leaf) and yield (26.28 q/ha) of chickpea compared to other variety. However, foliar application of (zinc 0.5%+boron 0.1%) had significant effect in influencing the growth attributes and yield of chickpea followed by single application of zinc 0.5% and boron 0.1% as compared to control. Foliar application of (zinc 0.5%+boron 0.1%) produced 26.47 % higher seed yield than control. This experiment suggested that the combined single foliar application of (zinc 0.5% + boron 0.1%) prove best treatment as compared to individual application of zinc 0.5% and boron 0.1%.

Agave REVEILLE1 regulates the onset and release of seasonal dormancy in Populus

PLANT PHYSIOLOGY (2022)

Degao Liu Dan Tang Meng Xie Jin Zhang Longmei Zhai

Abstract Deciduous woody plants like poplar (Populus spp.) have seasonal bud dormancy. It has been challenging to simultaneously delay the onset of bud dormancy in the fall and advance bud break in the spring, as bud dormancy, and bud break were thought to be controlled by different genetic factors. Here, we demonstrate that heterologous expression of the REVEILLE1 gene (named AaRVE1) from Agave (Agave americana) not only delays the onset of bud dormancy but also accelerates bud break in poplar in field trials. AaRVE1 heterologous expression increases poplar biomass yield by 166% in the greenhouse. Furthermore, we reveal that heterologous expression of AaRVE1 increases cytokinin contents, represses multiple dormancy-related genes, and up-regulates bud break-related genes, and that AaRVE1 functions as a transcriptional repressor and regulates the activity of the DORMANCY-ASSOCIATED PROTEIN 1 (DRM1) promoter. Our findings demonstrate that AaRVE1 appears to function as a regulator of bud dormancy and bud break, which has important implications for extending the growing season of deciduous trees in frost-free temperate and subtropical regions to increase crop yield.

Rahul Kumar Sanjay Kumar Yogesh Chandra Yadav

An experiment entitled “Variability studies for yield and yield in attributing traits in gladiolus (Gladiolus L.)” carried out at the Horticulture Research Farm, Department of applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow (U.P.) during the year 2009–10. The observation were recorded on nineteen yield and yield attributing traits in gladiolus viz., plant heigh (cm), leaf width (cm), number of days taken spike initiation, number of days taken for full emergence of spike, number of days taken for floret to show colour, number of days taken for first floret to open, number of florets opens at one spike length (cm), number of florets per spike weight (g). Number of days taken for harvesting of spike, number of shoots per plant, number of corms per Plant, weight of corms per plant (g), size of corms per plant (cm), number of cormels per plant and weight of corms per plot (kg). the experiment was laid out in Randomized Block Design (RBD) with three replications. The row to row and plant to plant spacing were maintained at 30 x 25 cm, respectively. The maximum weight of corms per plot was recorded in Rigency (0.964kg) followed by Picardy (0.780kg) and Tiger Flame (0.741kg) and minimum weight of corms was recorded in Eurovision (0.519kg), respectively.
