Effect of Growth, Physiological Aspects and Yield of Cabbage (Brassica oleracea L. cv Rareball) in Knolkhol and Broad Bean Intercropping System under Imphal West Condition

Abstract

An investigation was carried out to study the effect of intercropping crops (knol khol and broad bean) on growth, physiological aspects and yield of Cabbage. Sole crop of Cabbage was grown and between the inter-row spaces knol khol/broad bean was intercropped in single/double row planting. Spacing of 60 x 30 cm between cabbage and 30 x 30 cm for knol khol and 30 x 20 cm for broad bean was adopted. Growth parameters were recorded for cabbage as sole crop and as intercropped with single/double row of knol khol / broad bean. Maximum fresh weight (376.80 g) and dry weight (45.10 g) of the plant were observed in cabbage as sole cropping at 75 DAT which is at par with cabbage intercropped with single row of broad bean with fresh weight (344.13 g) and dry weight (41.56 g). However, on complete analysis of the physiological parameters, it can be concluded that cabbage sole cropping, recorded highest harvest index (64%), net assimilation rate (0.0344 g m -2 day -1 ), plant growth efficiency (30.30%), crop growth rate (2.08 g cm -2 day -1 ), relative growth rate (0.0306 g g -1 day -1 ) except leaf area index in which cabbage intercropped with single row of broad bean (1.16), exhibited maximum. Superiority in physiological parameters like leaf area index (1.16) and harvest index (64.00 %) was recorded in Cabbage with single row broad bean and sole crop of cabbage, respectively. The maximum weight of the head (875.54 g), the maximum compactness (30.30) and maximum yield was found 48.2 t/ha in cabbage sole cropping (T 1 ) which remained at par with cabbage intercropped with single row (776.51 g) of broad bean (T 4 ), (29.78) and 44.71 t/ha. Remarkable variation was observed in the performance of cabbage intercropped knol khol and broad bean under Imphal west condition.

Study on Different Vegetable based Intercrops in Cabbage for Assessing Growth, Yield and Economic Viability

“…It is widely reported that in most cases the main crop in an intercropping system does not perform as well as it should as in monoculture and does not reach as high a yield level due to an increased competition among intercropped plants for light, soil nutrients and water (Willey, 1979). Similar reports by Ananda et al, (2018) reported reduced performance of cabbage as intercrop which might be owned to the fact that sole cropped cabbage showed better performance in terms harvest index, net assimilation rate, plant growth efficiency, crop growth rate and relative growth rate. Poor performance of intercropped cabbage for these attributes may have caused negative impact on the yield parameters of cabbage as an intercrop.…”

“…Intercropping did not produce a pronounced effect on the total dry matter of cabbage head (Table 2) which are in confrontation with the studies by Ananda et al, (2018) who reported that the dry matter was maximum in cabbage grown as sole crop.…”

Potentiality of intercropping in managing Diamondback moth (Plutella xylostella)

“…Analysis of economics (B:C ratio) had shown that the highest returns were obtained with cabbage in combination with intercrops Mawnai et al (2021). Moreover, it was also noticed that the weight of the cabbage head was significantly influenced by intercropping (Ananda et al 2018).…”

Effect of different sources of organic fertilizers on crop growth and yield of cabbage

“…The polar and equatorial diameter of the head were measured, as well as the head circumference. The Compactness of the head is measured in terms of the 'Z' value by using the following formula shown below (Bhat et al, 2017), and the harvest index was calculated as the ratio of net head weight to gross head weight (Ananda et al, 2018). Net head weight was measured by collecting five heads separately and weighing them, and the yield per plot and yield per hectare were calculated accordingly.…”
