ABSTRACT
A research to investigate the performance on growth and yield of two varities with regard to various no.of seedlings hill-1 was conducted at the field of IAAS, Lamjung Campus, Sundarbazar during the period from June 2012 to Dec 2012. The experiment comprised two varieties viz. Makwanpur-1 and Ramdhan-1and three levels of seedlings hill-1 viz. 1, 2 and 4 seedlings hill-1. The experiment was laid out in a randomized complete block design with three replications. The treatments were randomly distributed to the plots within each block. The interaction effect of the varieties and number of seedlings hill-1 had significant effect on all the agronomic parameters except non-effective grains panicle-1, sterility % and harvest index. Results showed that Makawanpur-1 variety of rice when transplanted @ 2 seedlings hill-1 yielded the best (8.423 t/ha) than other combinations at Sundarbazar.
KEY WORDS: Makwanpur-1, Ramdhan, number of seedlings/hill, growth and yield.
INTRODUCTION:
Rice(Oryza sativa L.) is generally annual monocot plant belonging to Graminae family. Typically grown in tropical , sub-tropical, as well as in temperate zone of world. The rice plant can grow to 1–1.8 m tall, occasionally more depending on the variety and soil fertility. It has long, slender leaves 50–100 cm long and 2–2.5 cm broad. Rice has a unique feature in field that rice plants are grown on flooded soils. Temporal dynamics of paddy rice fields can be characterized by three main periods:
(1) the flooding and rice transplanting period; (2) the growing period (vegetative growth, reproductive, and ripening stages); and (3) the fallow period after harvest.
