Effect of planting pattern and nutrient management on yield and yield attributing characters of teosinte (Euchluena maxicana) + ricebean (Vigna umbelluta) intercropping

Abstract

The experiment conducted at Ranchi, during Kharif 1994 and 1995 to study the effect of planting pattern and nutrients management on forage production of teosinte [Euchlaena mexicana (L.) Schard] + ricebean [Vigna umbellata (thunb.) Ohwi & Ohashi] intercropping, indicated that teosinte grown in association of ricebean in 2 : 1 row ratio and fertilized with 75% of the recommended dose of nutrient (1 00% NPK : for teosinte 100 50 : 25 and for ricebean 30:60:25 kglha) produced significantly : the highest green forage (245.70 @ha) yield. However, the highest dry matter (41.46 @ha) and crude protein (5.24 @a) yields were recorded from the treatment receiving 75 and 100% of the recommended dose of nutrient respectively under 2 : 1 row - arrangement and they were significantly superior to rest of the combinations. The interaction effect of 100% of the recommended dose of nutrient with 2 : 1 row ratio planting pattern also produced maximum plant population. The higher levels (75% or 100%) of nutrients when combined with 1 : 2 stand of teosinte and ricebean recorded the highest plant height in ricebean and maximum number of tillers in teosinte and were significantly superior to rest of the treatment combination.
