Quality attributes of pea and oat in an intercropping system in rice fallows as influenced by integrated nutrient management

Author(s): Khumlo Levish Chongloi and KK Sharma
Abstract: A field experiment was conducted at two different areas of the Instructional-Cum-Research (ICR) farm of the Assam Agricultural University, Jorhat in 2014-15 and 2015-16 to study the “quality attributes of pea and oat in an intercropping system in rice fallows as influenced by integrated nutrient management”. The treatments consist of four intercropping system viz. C1: sole oats, C2: sole pea, C3: 3:2 row proportions and C4: 3:3 row proportion of oat+pea intercropping and four integrated nutrient management Viz., F1: RDF (inorganics), F2: 50% N of RDF + 50% N through FYM, F3: 50 % N of RDF + 50% N through vermicompost and F4: 50%N through FYM + 50% N through vermicompost. Thus sixteen treatment combinations were laid out in split plot design with three replications with intercropping system in the main plots and INM in the sub-plots. The soils of the experimental site were acidic in reaction, sandy loam in texture, medium in OC, low in available N and P2O5 and medium in K2O.Intercropping of pea with oat could not out yield the sole pea in terms of crude protein content, crude protein yield, nutrient content and uptakes in both the years however among the intercropping system the highest crude protein content, crude protein yield, nutrient content and uptakes was recorded in 3:3 row proportions of pea+oat in both the years of experimentations. The crude protein content, crude protein yield, nutrient content and uptakes due to integrated nutrient management was found to be highest at 50% N of RDF + 50% N through vermicompost during the years of experimentation. The crude protein content of oat was not affected by intercropping system, however the highest crude protein content of 10.36 and 10.46% was recorded in 50% N of RDF + 50% N through vermicompost followed by 50% N of RDF + 50% N through FYM during 2014-15 and 2015-16, respectively. The higher crude protein yield was recorded in sole oats in both the years of experiment. Among the intercropping 3:2 gave the highest value of 3.84 and 4.43q/ha crude protein yield during 2014-15 and 2015-16, respectively. The N, P, K, Zn and Fe content of oats was found to be significantly higher in 3:3 row proportions of pea+oat intercropping over the sole cropping of oat however the nutrient uptakes were found to be highest in sole oat in both the years. Among the intercropping systems nutrient uptakes observed in C3 (3:2 row proportions) was higher than C4 (3:3 row proportions of pea+oat intercropping) in both the years of experimentation. Application of nutrients at 50% N of RDF + 50% N through vermicompost (F3) resulted significantly higher nutrient content and uptakes of oats as compared to F1 (100% RDF), F2 (50% N of RDF + 50% N through FYM) and F4 (100% organic i.e. 50% N of vermicompost + 50% N through vermicompost) in both the years. Therefore, in pea and oat intercropping system under rice fallows, it can be recommended to apply 50% RDF through vermicompost + 50% RDF through inorganic fertilizers, which will increase the nutrient content and uptake of the crops with 3:3 row proportions of pea+oat intercropping systems
