System productivity enhancement in coconut (Cocos nucifera) garden by intercropping with flower crops in Assam

Abstract

The field experiment was conducted at Horticultural Research Station, Kahikuchi of Assam Agricultural University for four consecutive years (2012–13 to 2015–16) to study the performance of flower crops as intercrop in adult coconut (Cocos nucifera) garden spaced at 7.5 m × 7.5 m taking five commercial flower crops, viz. Tuberose (Polianthes tuberosa) var. Single, Gerbera (Gerbera jamesonii) var. Red Monarch, Bird of Paradise (Strelitzia reginae) var. Glauca, Gladiolus (Gladiolus grandiflorus) var. Oscar, Marigold (Tagetes erecta) var. Siracole along with a control (coconut monocrop). Results showed that number of leaves on the crown, annual leaf production, number of inflorescences per palm and nut yield of coconut was not significantly influenced by the flower crops grown in coconut garden. Significantly the highest total coconut equivalent yield of 48920 nuts/ha/year was obtained in coconut + gerbera followed by coconut + tuberose (42717 nuts/ha/year), coconut + gladiolus (42334 nuts/ha/year) and the lowest in coconut as monocrop (10430 nuts/ha/year). Intercropping system of growing gerbera in coconut garden registered the highest net income (` 380075/ha) and B:C ratio (3.5) followed by tuberose (` 323420/ha and 3.1), gladiolus (` 315090/ha and 2.9), marigold (` 233050/ha and 2.8) and the lowest net income of ` 64050/ha and B:C ratio (1.6) obtained in monocropping of coconut.

Synergizing Sustainability: Integrated Nutrient Management and Intercropping for Optimal Coconut Cultivation in South India

“…This balanced approach provides a sustainable and profitable model for farmers looking to maximize their returns from intercropping systems. The outcomes [26] of the research support the evidence that intercropping can increase the primary crop's production of nuts. The coordinated use of resources increases overall efficiency, leading to increased coconut crop yields [27].…”

Yield assessment of intercropping of bitter gourd (Momordica charantia) in coconut (Cocos nucifera)

“…Basavaraju et al (2011) [1] also reported increased economic returns in the intercropping systems of coconut with medicinal and aromatic plants. It is well accepted that inter cropping system under coconut is more profitable than mono cropping which promises to the farmers a lot besides generating additional employment opportunity (Nath, 2002) [3] .…”
