High temperature induced by climatic fluctuations are an important threat for plant growth, development and quality of agricultural produces. Adaptableness to environmental changes generally derives from a large set genetic traits affecting physio-morphological, biochemical agronomic parameters. Therefore, the identification genotypes with higher yield good parameters at high temperatures is becoming increasingly necessary future breeding programs. Here, we analyzed performance different...
Asian cultivars were predominantly represented in global rice panel selected for sequencing and to identify novel alleles drought tolerance. Diverse genetic resources adapted Indian subcontinent not much spite harboring useful that could improve agronomic traits, stress resilience productivity. These accessions are valuable resource developing varieties suited different ecosystem experiences varying level, at crop stages. A core collection of germplasm Southwestern peninsular genotyped using...
The study, conducted at the Department of Plantation, Spices, Medicinal, and Aromatic Crops, College Agriculture, Vellayani, aimed to assess impact foliar application chitosan on photosynthetic performance in drought-stressed long pepper (Piper longum L.). Two concentrations (0.5 1 g L-1) were applied drought stress (irrigated 60 75 % field capacities) parameters observed. Chitosan-treated plants, particularly L-1 concentration, exhibited significantly higher relative water content, stomatal...
An experiment was conducted to detect the variability, heritability and genetic advance for morphophysiologcal yield related traits in rice under drought stress.For this study 81 genotypes were phenotyped tolerance field condition 9×9 lattice square design with two replicates at Regional Agricultural Research Station, Pattambi during month of Sept Dec 2017.Drought stress induced from panicle initiation stage a period 25 consecutive days by withdrawing irrigation.The result obtained current...
The diminishing nutritional quality of rice with increasing concentrations atmospheric CO 2 is currently a major global concern. present study was designed the objective assessing impact biofertilisers on grain and iron homeostasis in under elevated . A completely randomised design four treatments ([KAU, POP (control), POP+Azolla, POP+PGPR, POP+AMF]), each replicated three times ambient conditions, followed. analysed data revealed that yield, quality, uptake translocation were modified an...
Aims: Banana bract mosaic virus (BBrMV) is a significant viral disease that adversely impacts the yield and quality of banana (Musa acuminata) fruits. Endophytes have been recognized as sustainable tool to enhance plant nutrient availability uptake. Piriformospora indica beneficial fungal root endophyte can improve utilization confer tolerance diverse abiotic biotic stresses in plants. The effect P. colonization on assimilation fruit BBrMV-infected plants still needs be better understood,...
The aim of the study was to physiologically and biochemically assess selectively fertilized coconut hybrids for their tolerance high-temperature stress. Conducted using a two-factorial Completely Randomized Design, research took place at Department Plant Physiology, College Agriculture, Vellayani, Trivandrum, between October 28, 2023, December 2023. Methodology involved cultivating six-month-old hybrid seedlings three varieties, Kerasree, Keraganga, Kerasankara, in polyhouse with pre-set...
Tomato (Solanum lycopersicum L.) reproduction is influenced by temperature, prominently impacting yield. The ideal daytime range between 25°C and 30°C the nighttime temperature around 20°C for tomato deviations of a few degrees from these temperatures can have negative effects. study assessed effect on pollen germination aimed to ascertain critical sterility germination. In an open field, 10 genotypes (Anagha, Manuprabha, Vellayani Vijay, Akshaya, Nandi, IIHR26372, Pusa Rohini, Arka Saurabh,...
Sustainable crop production depends more on maintaining good soil health. Biochar significantly improves the soil's physical, chemical, biological and nutritional properties while aiding in carbon sequestration. Biofertilizers, which promote nutrient cycling, heavy metal chelation of plant growth substances are crucial to sustainable agriculture. While individual benefits biochar biofertilizers well-documented, their combined effect vegetable farming is less studied. The synergistic...
Guava (Psidium guajava L.), prized for its nutritional and economic value, thrives in tropical subtropical regions, making it a suitable candidate urban container farming. This study, conducted at the Department of Fruit Science, College Agriculture, Vellayani, evaluated growth response five guava varieties under 80-liter air-pot cultivation. Among varieties, Arka Mridula excelled vegetative parameters, including plant height (72.33 cm) biochemical traits like total chlorophyll (0.98...
A study was undertaken to investigate the effects of chitosan (CS) at varying concentrations (0 g/L, 1 2 3 g/L and 4 g/L) on Piper longum. CS, a naturally occurring polysaccharide, has garnered attention for its potential enhance plant growth yield. The experiment involved foliar applications CS 2, 6 months after planting (MAP), followed by observations month postapplication (3, 5 7 MAP). This allowed comprehensive assessment impact growth, physiological, biochemical yield parameters P....
Isolation of high-quality RNA from seeds is very critical for seed specific gene analysis. An investigation and comparison on the use CTAB, SDS TRIzol extraction procedures to extract grains medical njavara rice were carried out in present study. These protocols either failed yield or resulted reduced with poor quality Njavara grains. The starch secondary metabolites hindered isolation resuspension precipitated contaminated pellets by co-precipitation. Hence, we modified protocol addition...
