Abstract
The integrated nutrient management is an important aspect of farming including agroforestry in order to reduce excess use of chemical fertilizers. In fact, the approach of INM lead to long term beneficial influence on crops/plants and the whole farm system. Looking to its important, the present study was carried out at the College Farm of N. M. College of Agriculture, Navsari Agricultural University, Navsari, Gujarat during the year of 2016-17. In the experiment, Surati Ravaiya variety of Brinjal (Solanum melongena L.) was tested under twenty-three years old Teak (Tectona grandis L. f.) plantation with 14 treatments of INM including control (Sole crop with 100% RDF i.e., NPK @ 100:50:50 kg/ha). Result showed that growing of brinjal crop in open condition (with recommended dose of fertilizer) resulted in significant increase in yield and economic return as compared to growing brinjal crop under teak with different INM treatments. Significantly maximum fruit yield (29.73 t/ha) was recorded in T14: 100 % RDF in open condition, followed by INM treatments- T1: 100 % RDF (19.61 t/ha) and T11: 75 % RDF + Vermicompost (18.29 t/ha) under teak plantation. In contrast, minimum fruit yield (8.65 t/ha) was noted in T2: Azotobactor under teak plantation. In the case of economics, net realization and benefit cost ratio (BCR) recorded in T14: 100 % RDF in open condition was Rs. 1,88,692.00/ha and 1:1.74, respectively. In the case of Brinjal based teak silvi-horti system, the highest net realization (Rs. 6,21,085.00/ha) and BCR (6.87) was recorded from T1: 100% RDF, followed by T11: 75 % RDF + Vermicompost with net realization of Rs. 105795.00 and BCR of 6.15. Therefore, teak farmers are suggested to grow brinjal under teak to obtain additional income.
