Impact of Chlormequat Chloride and Maleic Hydrazide on Morpho-physiological Parameters in Rice (Oryza Sativa L.)

K. Tressa Naidu, A. R. Nirmal Kumar, V. Umamahesh & P. Maheswara Reddy · Journal of Advances in Biology & Biotechnology · 2026

Rice is a key staple crop supporting global food security, particularly in Asia. In coastal rice-growing regions, increasing climate variability, including heavy rainfall and flooding at maturity, has led to greater incidences of lodging and pre-harvest sprouting, resulting in yi...

Influence of Chlormequat Chloride and Maleic Hydrazide on Yield and Yield Components of Rice (Oryza sativa L.)

K. Tressa Naidu, A. R. Nirmal Kumar, V. Umamahesh & P. Maheswara Reddy · International Journal of Plant & Soil Science · 2026

Rice productivity is often affected by climate variability and lodging, especially in coastal regions, leading to yield losses and poor grain quality. Plant growth regulators such as chlormequat chloride and maleic hydrazide are used to modify plant growth and improve assimilate...

Effects of Nanoscale Silica Particles on Nitrogen, Phosphorus, and Potassium Content and Uptake in Rice

D. Gopal, T. N. V. K. V. Prasad, CH. Bhargava Rami Reddy, A. R. Nirmal Kumar & R. Naseeruddin · International Journal of Plant & Soil Science · 2026

Silica nanoparticles (SiNPs) are being examined as foliar inputs because silicon can influence plant growth, stress responses, and nutrient acquisition. This pot experiment evaluated the effects of foliar-applied SiNPs on nitrogen (N), phosphorus (P), and potassium (K) content an...
