Mango based agri-horti system on degraded lands in Doon Valley

Abstract

A field experiment was conducted for seven years (1995-2001) to study the performance of mango cv. Mall ika based Agri-Horti systems on degraded gravelly riverbed lands in Doon Valley. Okra-toria cropping system gave maximum gross income ofRs. 26015 ha'' year' and superseded by 298.5, 142.9, 73.1, 66.9, 26.6 and 24.3 per cent more over without intercrop, clusterbean-toria, pigeonpea, sesame-toria, blackgram-toria and cowpea-toria cropping systems, respectively. Okra-toria cropping system proved more beneficial with highest net profit of Rs.7423 ha' year' and maximum benefit:cost ratio of 1.40 followed by cowpea-toria (Rs. 4285 ha-1 year-1 with B:C ratio of 1.26), blackgram-toria (Rs. 4086 he year' with B:C ratio of 1.25), pigeonpea (Rs. 1803 ha-1 year with B:C ratio of 1.14), sesame-toria (Rs. 1222 ha-1 year-1 with B:C ratio of 1.09), and without intercrop (Rs. -764 ha-1 year-1 with B:C ratio of 0.90).Pigeonpea supplemented highest amount ofnitrogen, phosphorus, potassium, calcium and magnesium through their residue followed by cowpea, okra, blackgram, sesame and toria. The plant growth characters, fruit yield and quality parameters of mango not influenced were adversely due to presence of any intercrop.
