Growth and yield of Vigna radiata L.) under Terminalia arjuna and Mitragyna parvifolia based agrisilvicultural system

Abstract

However, only the plant height was found to be highest under Arjun, followed by Kalam trees. Among all the varieties tested, K-851 variety showed superiority for number of leaves (12.31) and number of branches per plant (3.96) and grain yield (2.66 gm per plant and 0.80 kg per plot) as compared to other varieties (at P=0.05). Therefore, this variety is suggested to grow in south Gujarat condition. Further, comparatively lower yield of crop under tree cover could be due to shade effect, which can be managed by regular pruning of tree branches.

Evaluation of Agronomic Performance of Green Gram Accessions Grown under Reduced Light Intensity in the Arid and Semi-Arid Areas of Kenya

“…The reduced light intensity probably allowed increased absorption of photosynthetically active radiation and thus enhancing the assimilation efficiency. The results are in line with [21] who reported that maximum grain yield of rice was realized under open direct sunshine; [12,20,22,27,28,32] who reported that shading reduced seed yield.…”

“…The accessions had a range of 49.9-54.7 cm plant height under shade net and a range of 49.9 -50.7 cm in control, open sunlight conditions. These results corroborate with the findings of [20,21] at Kerala Agricultural University, [22] and [23] at Bangladesh, [24] at Kyushu University, Japan, [25] at Phetchaburi, Thailand; [26] at Egypt and [27] at Japan; [28] in Thailand, which showed that plants grown under reduced light intensity had a higher plant height as compared to those under direct sunlight. Higher plant height under the shade could be due to a reduction in the rate of evaporation of the water from the soil providing cooler root zone leading to enhanced root development which probably led to higher plant height and also due to photosynthesis rate which may be proportional to chlorophyll content only at low light intensity.…”

Integration of Vigna mungo under Grewia optiva based Traditional Agroforestry System

“…They attributed this decline to higher auxin production in shade condition which ultimately suppressed the growth of lateral branches. Kumar et al, (2015) also reported increase in number of branches of Vigna radiata under controlled condition as compared to canopy of Terminalia arjuna and Mitragyna parvifolia and attributed this increase to higher light intensities under control condition.…”
