EFFECT OF DIFFERENT NITROGEN LEVELS AND PLANT SPACING ON THE GROWTH AND YIELD OF BASMATI RICE (ORYZA SATIVA L.)

Abstract

The "Effect of different nitrogen levels and plant spacing on the growth and yield of basmati rice (Oryza sativa L.)" in the Rabi season crop of 2023-2024 was the subject of a field experiment conducted at Rama University at Mandhana, Kanpur. Nitrogen levels (Kg ha-1)- N0: 0(Kg ha-1), N1: 40(Kg ha-1), N2: 60(Kg ha-1), N3: 80(Kg ha-1), N4: 100(Kg ha-1) and Plant geometry (cm)- G1-20 × 15, G2-15 × 15, G3-20 × 10, G4-15 × 10 were the five treatments with N levels and four treatment with plant geometry that were included in the experiment. Three replications of each treatment were carried out using a Randomized block design (Factorial) Replications was the rice crop used in the experiment. The experimental soil had a pH between 7.2 and 7.8, medium levels of organic carbon, and medium levels of potassium, phosphorus, and nitrogen. Greater nutrient uptake was found to be significantly greater in this pattern, and the results seemed to show that the five treatments with N levels and four treatments with plant geometry N4-100 (kg ha-1) had significant growth, yield qualities, and grain yield varied with the different nutrient levels. The farmer's methods produce the lowest grain yield, growth traits, and yield qualities. The decomposition of crop residues and the use of organic manures resulted in an improvement in soil quality at the five treatments with N levels and four treatments with plant geometry. With N4-100 (kg ha-1 and G3 treatments, the N levels have the highest net return and benefit cost ratio.
