Continuous use of chemical fertilizers poses soil health issues, whereas organic manures alone are not able to fulfil the requirements of highly nutrient-demanding crops. Indian soils are deficient in NPS, leading to low yield potential, so the only option left is to concentrate on alternate strategies like Integrated Nutrient Management (INM) to maintain the soil fertility. In this view, research was carried out to study the effect of integrated nutrient management on plant growth, yield and quality of papaya (L.) cv. Red Lady under Carica papaya Punjab conditions. The main objectives of this study were to adopt organic manures instead of relying only on chemical fertilizers or to find the appropriate combination of organic manures along with chemical and bio-fertilizers. The dose of chemical fertilizers was kept constant (50% for all treatments), whereas different concentrations of organic manures and bio-fertilizers were added. Among all the treatments, the application of 50% NPK + 20 kg FYM + 100 g + 100 g PSB resulted in the maximum plant height, stem girth, fruit length, fruit width, Azospirillum and yield. Likewise, all the fruit quality parameters such as TSS, firmness, total sugars, reducing sugars, non-reducing sugars and ascorbic acid were also improved by the same treatment. Hence, integrated nutrient management significantly improved the vegetative growth, yield and quality of papaya cv. Red Lady when 20 kg of FYM and 100g of were applied along with 50% NPK.

Fertigation Improves Fruit Yield and Quality of Papaya
II International Symposium on Papaya, 2010
To assess the influence of fertigation on nutrient use and yield improvement in papaya, investigations were carried out in papaya cv. Co.7 during 2006-2008 at Horticultural College and Research Institute, Coimbatore. Nitrogen and potassium were fed through drip as urea and muriate of potash while phosphorous was applied through soil as single super phosphate. The treatments include 100% recommended dose of N and K 2 O through drip (T 1), 75% recommended dose of N and K 2 O through drip (T 2), 50% recommended dose of N and K 2 O through drip (T 3) and soil application of recommended dose of fertilisers (50 g N:50 g P 2 O 5 :50 g K 2 O per plant) at bimonthly interval starting from 3 rd month after planting (MAP). Application of 100% recommended dose of N and K 2 O (50 g N and 50 g K 2 O) through drip irrigation (T 1) resulted in flowering at the shortest height (96.32 cm). Plant height, stem girth and number of leaves were also found significantly higher in T 1. Leaf N and K showed significant changes while P exhibited no variations among the treatments. Treatment, T 1 resulted in more number of fruits, fruit weight, TSS and low fruit cavity index. The increase in number of fruits and fruit weight is attributed for higher fruit yield per tree (73.97 kg) and the resultant total fruit yield per hectare (184.9 tonnes) with high B:C ratio (1:1.97) in plants treated with 100% recommended dose of N and K 2 O (50 g N and 50 g K 2 O) through drip irrigation, in addition to soil application of 50 g P 2 O 5. It is concluded that fertigation of papaya cv. Co.7 with 100% recommended dose of N and K 2 O through drip (50 g N at 6.25 g/plant/week and 50 g K 2 O at 6.25 g/plant/week for a two months period), in addition to soil application of 50 g P 2 O 5 in bimonthly intervals resulted in maximum fruit yield. The physiological as well as biochemical changes in plants due to fertigation are also discussed in this paper.
