Maize (Zea mays L.) is an important crop grown for food, feed, and energy. In general, maize yield decreased due to drought stress during the reproductive stages, and, hence, it critical improve grain under drought. A field experiment was conducted with a split-plot design. The main factor irrigation regime viz. well-irrigated conditions withholding from tasseling filling 21 days. subplots include six treatments, namely, (i) control (water spray), (ii) zinc oxide @ 100 ppm, (iii) manganese...

The stay-green character is a crucial trait linked to delayed leaf senescence, which enables the plant continue photosynthetic activity for an extended time under early and terminal drought. Reduced water availability causes lower chlorophyll content eventually poor yield in maize. objectives were quantify effects of irrigation regimes, nanocomposite levels physiological parameters, attributes main plot treatments comprised well irrigated withheld irrigation, while sub consisted different...

The utilization of various agrochemicals in crop production technology leads to soil health and fertility depletion. Multiple measures have been taken revitalize the polluted soil. In this context, organic agriculture has increased over past few years overcome detrimental effects extensive modern agricultural practices. Several traditional formulations, such as panchagavya, jeevamurtha, beejamurtha, bokashi, etc., are vital converting farmlands into organic. Various countries their own...

Permanent manurial experiment was started from the year 1909 at Tamil Nadu Agricultural University, Coimbatore, in order to assess impact of continuous addition organic and mineral fertilizers on crop yield soil quality. Conducting a long-term fixed site with cropping will help monitor changes quality yields sustainability also guide developing strategies for fertilizer management while minimizing environmental degradation. From results revealed that application 100% NPK + Farmyard manure...

A field experiment was conducted at Agricultural College and Research Institute, Madurai to study the combined effect of intercropping weed management practices on control in irrigated cotton during year 2016. Cotton + sorghum system registered significantly lower density dry matter production all stages crop growth, while sole recorded higher production. In practices, lesser were under pre-emergence application pendimethalin @ 1.0 kg a.i. ha-1 20 DAS. At 40 60 DAS hand weeding twice matter....

Maize is a versatile crop that primarily used as human food and animal feed. It also fundamental raw material utilized in various industrial products owing to its nutritional value. One of the most harmful abiotic stresses maize cultivation drought. A water shortage caused by drought limits development yield because there less available moisture. Water stress causes restricted stomatal opening, enhanced photorespiration accelerated photoreduction oxygen chloroplast. Eventually, this...

Application of highly sustainable and productive inputs is required to increase food production in order feed the growing world population while using same amount land. Thus, its very first attempt, Tamil Nadu Agricultural University (TNAU), Coimbatore, Nadu, has produced water soluble fertilisers (WSF) named as TNAU-Water Soluble Fertilizers (TNAU-WSF), it necessary optimise on various crops. One most essential vegetables Indian cuisine small onion, which a high demand but low productivity....

Long Term Fertilizer experiment was initiated to monitor the continuous manuring and fertilization under intensive cropping changes in soil properties concerning physical, chemical biological characteristics crop productivity. The experimental belongs sandy clay loam (Vertic Ustropept) with ten different nutrient management practices followed replicated thrice by adoption of Randomised Block Design (RBD). Continuous use inorganic fertilizer along Farmyard manure (FYM) could increase...

Water availability is becoming a significant concern for crop production worldwide. In light of this, study was conducted in maize to explore the effectiveness various osmoprotectants including sodium nitroprusside nanoparticles (SNP NP) at concentration 90 ppm, melatonin (MEL), 25 ppm and salicylic acid (SA) 100 mitigating adverse effects drought, by evaluating their impact on morpho-physiological, biochemical yield attributes (Zea mays L.). Drought stress induced withholding irrigation...

Enhancing the food production for growing world population has needed application of highly sustainable and efficient inputs to produce more per unit land. Hence, Tamil Nadu Agricultural University (TNAU), Coimbatore, produced Water soluble fertilizers (WSF) in its maiden attempt it is necessary optimize on different crops. Small onion one most important vegetables Indian diet high demand but low productivity. To enhance crop productivity quality small onions, TNAU-WSF was taken up. A field...

The F2 segregating generation of two crosses viz., Anna (R) 4 x IR 64 Pup 1 and Samba mahsuri were evaluated for variability parameters frequency distribution. results revealed that both the exhibited high PCV GCV traits number tillers per plant, productive filled grains panicle, shoot P content single plant yield. height, hundred grain weight, content, yield showed heritability coupled with genetic advance as cent mean indicating presence additive gene effect selection these may be...

Thirty rice genotypes were evaluated for ten morphological traits along with phosphorous content in shoot and grains to examine the nature magnitude of variability, character association path coefficient. Among all traits, single plant yield exhibited highest estimate PCV GCV followed by content, number productive tillers per plant, filled panicle hundred grain weight indicated that choice these would be valuable. High heritability jointly high genetic advance as percent mean observed...
