Abstract: Field experiments were conducted to test the effect of 12 fertilizer treatments comprising of organic and inorganic fertilizer doses on productivity of pearl millet – wheat sequence under semi-arid Inceptisols at Agra during 2008 and 2009. The treatments tested were T1: Control; T2: 100% recommended dose of fertilizer (RDF) N; T3: 100% RDF NP; T4: 100% RDF NPK; T5: 100% RDF N + ZnSO4 @ 25 kg/ha; T6: 100% RDF N + FYM @ 10 t/ha; T7: 100% RDF N + vermicompost @ 2.5 t/ha; T8: 100% RDF N + Sulphur @ 25 kg/ha; T9: FYM 10 t/ha; T10: Vermicompost @ 2.5 t /ha; T11: 100% RDF NPK + FYM @ 10 t + S @ 25 kg + ZnSO4 @ 25 kg/ha; and T12: 150% RDF NPK. The treatments were assessed for different yield attributes, plant uptake of nutrients, grain yield and protein parameters. The analysis of variance indicated that the treatments had a significant effect on different parameters studied in both pearl millet and wheat crops. The treatments had a significant effect on the yield of crops in both years. The quality of crops in respect of protein, N, P and K uptake increased significantly with the conjoint use of organic manures and inorganic fertilizers. Maximum plant uptake of nutrients, grain yield and protein of crops could be attained with the application of balanced use of organic and inorganic fertilizers. Ranks were assigned to treatments for their performance for different parameters over years. The cumulative rank sum of treatments for different parameters indicated that T11: 100% RDF NPK + FYM @ 10 t/ha + ZnSO4 @ 25 kg/ha + S @ 25 kg/ha was superior with lowest rank sum, followed by T12: 150% RDF NPK for attaining maximum yield, plant uptake, protein and yield attributes under semi-arid Inceptisols.
