The experiment consisted of two intercrops (French bean and amaranthus), three nutrient levels (NL 100, NL 75 and NL 50) and two planting methods (normal row planting and paired row planting).
Among the three cropping system viz. Chilli – French bean, chilli – amaranthus and pure crop system, performance of chilli in chilli – French bean system was the best. All the growth and yield attributes, nutrient uptake and yield of chilli in chilli – French bean system was superior to chilli – amaranthus system and pure crop system.
Better growth and yield performance of chilli was observed at 100 per cent of the nutrient dose for both the crops. The maximum benefit from chilli intercropping system was also realized at this level of nutrient.
Intercrop yield of chilli was not influenced by planting geometry.
Intercrop yield of amaranthus significantly increased with nutrient levels. Intercrop yield of amaranthus at 100 and 75 per cent nutrient does was significantly higher than intercrop yield of amaranthus at 50 per cent nutrient dose and pure crop yield.
Performance of both pure and intercropped French bean was very poor hence this crop could not be recommended for summer rice fallow.
Higher LER, LEC, ATER, CEY, monetary return based on LER, gross return, net return, return per rupee invested and per day return revealed the bio and economic suitability of chilli amaranthus system. Bio and economic suitability of chilli intercropping system was maximum when both crops were given 100 per cent of the nutrient dose.
Nutrient status of the soil was not affected by intercrops, nutrient levels and planting geometry. A positive build up of all the nutrients in the soil revealed the sustainable nature of these systems.
The results indicated that, French bean was not ideal for summer rice fallows. To reap the maximum biological and economic advantage, both the crops should be supplied with 100 per cent of the recommended dose. Chilli – amaranthus intercropping system can be recommended as an economically viable, biologically suitable and a sustainable cropping system for summer rice fallows of Kerala.
