We studied the effect of integrated nutrient management (INM) combinations
on supplement of plant nutrient for quantitative and qualitative fruit production
in sapota. Thus, 17 combinations of INM practices were evaluated on fruit yield
of sapota and nutrient availability in a Vertisol of Chambal region, India. The
results demonstrated that almost all treatment combinations comprised of
recommended dose of fertilizer (RDF), i.e. 1,000:500:500 g NPK plant−1 with
application of organic and inorganic sources of nutrients had a significant effect
on the fruit yield of sapota, soil microbial biomass, NPK content of leaf, fruit and
soil over control (T1). Among different treatments, application of 2/3rd part of
RDF + 50 kg FYM + 250 g Azospirillum + 250 g Azotobacter plant−1 (T11)
significantly enhanced the number of fruits plant−1 (327.88), yield plant−1
(29.03 kg) and yield ha−1 (4.52 t). However, the soil microbial count of fungi
(8.89 cfu g−1 soil), bacteria (11.19 cfu g−1 soil) and actinomycetes (5.60 cfu g−1
soil) at fruit harvest was higher under the 2/3 of RDF +10 kg vermicompost +
250 g Azospirillum + 250 g Azotobacter plant−1 (T15). The leaf nitrogen content (N,
2.03%) was higher in T15, while phosphorus (P, 0.28%) and potassium (K, 1.80%)
contentwere higher in T11. It is evident that treatment T11 increased fruit yield by
32% in Sapota cv. Kalipatti compared to control. Therefore, combined application
of nutrient sources proved not only beneficial for enhancing fruit yield of
sapota but also sustaining soil health in Chambal region of south-eastern
Rajasthan.
