36. Intercropping studies in peanut (arachis hypogaea l.).

J. Agronomy & Crop Science, 168, 1992, pp. 34-36

With a view to study the effect of intercropping and plant geometrics in peanut cv. VRI-1, a field experiment was conducted at Area Agronomic

Centre, Tamil Nadu, India, during winter season 1989.

Three intercrops viz., pigeonpea, sunflower and finger millet were tested at two plant geometrics viz., paired rows of 40/20 cm and 45/15 cm.

Peanut is a major oilseed crop in India with an annual production ranging from 5 to 7.5 mt. over the last decade. With the increase in the cost of inputs like seeds, fertilizers and labour, there tends to exist a declining trend in monetary return from rising a pure crop.

Significant difference in pod yield of peanut among various treatments was observed. Intercropping with pigeonpea did not affect the pod yield of peanut significantly. Sunflower or finger millet as intercrop drastically reduced the pod yield of peanut. Plant geometrics, though influencing the growth characters, such as, plant height, LAI, failed to alter the pod yield. Larger competition free period of peanut and pigeonpea, and the potentiality of pigeonpea, by virtue of deep root system, to forage nutrients in deeper layers were attributable to less competitive effect of this intercrop on the base crop. In peanut intercropped with sunflower and finger millet, the growth, yield attributes and yield of the base crop, peanut, were greatly affected, obviously due to the competitive effect of these intercrops for light and nutrients.

When peanut kernel equivalent for different intercropping situations was considered, peanut intercropped with pigeonpea at 45/15 cm paired row registered higher equivalent yield of 2221 kg ha-1. Same treatment also recorded the highest net profit (Rs 13901 ha-1) followed by peanut intercropped with pigeonpea at 40/20 cm paired row (Rs 12633 ha-1).

Raising sunflower or finger millet as intercrops drastically reduced the net income over pure crop. Return per rupee invested was high (2.17) in peanut + pigeonpea at 45/15 cm paired row. Peanut intercropped with sunflower or finger millet recorded less return per rupee invested when compared to pure peanut.
