EFFECT ()F NITROGEN AND MOLYBDENUM ON THE GROWTH AND YIELD OF GARDEN PEA (Pisum sativum L.)

Abstract

A field experiment was conducted at the research farm of Shcr-c-Bangla Agricultural Univ ersity, Dhaka. during December 2006 to February 2007 to stud) the effects of nitrogen and mol) bdenum on the growth and yield of garden pea. 'I he experiment was laid out in a Randomized Complete Block Design (ReBD) with three replications of each treatment. The unit plot size was 5 m2 (2.5 III x 2.0 m). There were 15 treatments combinations in the experiment comprising 5 levels of N (0. 30, 60. 90 & 120 kg/ha designated as Nil. N,o. N6().NI)O& N 120. rcspcctiv ely) and 3 levels of Mo (0. 0.4 &0.8 kg/ha designated as Moo. MOo4 & MOl)R. rcspcctiv ely). The indiv idual and combined effects of nitrogen (N) and molybdenum (Mo) on growth and yield of garden pea plants were studied. 'I he individual and interaction effect of Nand Mo on growth and ) ield was found significant. Nitrogen (N) @ 90 kg/ha gave the highest number of branches per plant. highest number of pods per plant highest pod length. highest green and matured seed weight per 10 pods. highest green and matured pod) ield but maximum plant height and number of seeds per pod were found under 120 kg N/ha. In case of molybdenum application the highest plant height, highest number of branches per plant highest pod length. highest seed weight per 10 pods w ere recorded in 0.4 kg Mo/ha. Molybdenum (Mo) @ 0.8 kg/ha gave the highest fresh weight of plant and highest fresh weight of pods. Ihc treatment combination of N120 .M004 produced the maximum plant height. highest number of pods per plant. highest fresh weight of plant. but the treatment combination of 90 kg NQoMoo t gave the maximum number of branches per plant. highest length of pod, highest number of seed per pod. highest seed weight per 10 pods. highest pod ) ield, maximum P. K and S content in plants. Lowest N. P. K and S content was found in control (NoMoo) treatment. From the present findings it can be concluded that application of N @ 90 kg/ha along with Mo @ 0.4 kg/ha is the most suitable combination to achiev e the maximum return from garden pea plants.
