Integrated nutrient management in litchi (Litchi chinensis Sonn.) cv. Muzaffarpur for yield and fruit quality at foothills of Arunachal Pradesh

Abstract

The present investigation to study Integrated Nutrient Management in Litchi (Litchi chinensis Sonn.) cv. Muzaffarpur for yield and fruit quality was carried out in 7 years old trees of uniform size during 2017 at Fruit Research Farm, Department of Fruit Science, College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh. The experiment was laid out in Randomized Block Design with 9 treatments and 3 replications. The treatments were T1=1000 g N+500 g P+500 g K (control)., T2=500 g N+250 g P+250 g K+ 50 kg Vermicompost., T3=500 g N+250 g P+250 g K+100 kg FYM., T4=500 g N+250 g P+250 g K+100 kg FYM+100 g PSM., T5=500 g N+250 g P+250 g K+100 kg FYM+150 g Azotobacter., T6=500g N+250 g P+250 g K+100 kg FYM+100 g VAM., T7= 500 g N+250 g P+250 g K+ 100 kg FYM+150 g Azotobacter +100 g PSM., T8=500 g N+250 g P+250 g K+ 100 kg FYM+150 g Azotobacter+100 g VAM., T9=500 g N+250 g P+250 g K+100 kg FYM +150 g Azotobacter +100 g PSM+100 g VAM. Experimental results revealed that the imposition of different treatments had a significant effect on yield and fruit quality of litchi. Maximum number of fruits per tree (1281), fruit yield (30.01 kg/tree), total sugar (26.14 %), reducing sugar (14.51 %) was observed in 500 g N+250 g P+250 g K+100 kg FYM+150 g Azotobacter+100 g PSM+100 g VAM (T9). The control 1000 g N+500 g P+500 g K recorded maximum fruit cracking. Application of 500 g N+250 g P+250 g K+100 kg FYM+150 g Azotobacter+100 g PSM+100 g VAM (T9) was most effective treatment with respect to yield and fruit quality of litchi in foothills of Arunachal Pradesh.
