“Influence of growth promoting substances to enhance flowering, fruiting and nut yield of cashew (Anacardium occidentale L.)†var. BPP- 8 (H 2/16) was carried out at All India Coordinated Research Project on Cashew, (OUAT), Ranasinghpur, Bhubaneswar, Odisha during the year 2016-17. The objective of the investigation was to study the effect of growth promoting substances on cashew with respect to flowering, nut yield and quality of nuts and apple. The experiment consisted of eight treatments of growth promoting substances along with control. The treatments are T1- NAA @ 50 ppm, T2- GA3 @ 50 ppm, T3- Kinetin @ 50 ppm, T4- ZnSO4 @ 0.5 %,T5- Borax @ 0.1 %, T6- ZnSO4 @ 0.5 % + Borax @ 0.1 %, T7- Seaweed extract @ 2 ml. L-1, T8- Water spray (Control). Growth promoting substances were applied at three stages viz. pre-blooming stage, flowering stage and after fruit set
except GA3 which was sprayed only once at pre-blooming stage. The experiment was laid out in Randomized Block Design (RBD) replicated thrice. Biometrical observations on vegetative characters, flowering characters, yield attributes and quality parameters were recorded.
The result revealed significantly positive impact of growth promoting substances on cashew. Foliar application of ZnSO4 @ 0.5 % recorded significantly higher number of hermaphrodite flowers (66.33), sex ratio (0.18), number of nuts per panicle (6.22), nut yield (12.63 kg/ tree), length (5.33 cm) and weight (65.37 g) of cashew apple. ZnSO4 @ 0.5 % + Borax @ 0.1 % also emerged as best treatment in terms of length (3.38 cm), breadth (2.79 cm) and nut weight (8.40 g), kernel weight (2.60 g) and number of nuts per kg (121.67). NAA had significantly better effect on quality of cashew apple viz. TSS (13.27 OBrix), starch (11.01 %) and sugar content (12.40 %).
Minimum fruit abscission percentage (91.83 %) was also recorded with foliar application of NAA @ 50 ppm. Maximum ascorbic acid content (5.23 mg/ 100 g) was recorded in spraying of Kinetin @ 50 ppm. Regarding the economics, spraying of ZnSO4 @ 0.5 % proved to be best over other
treatments in terms of gross return (Rs. 1, 77,333.33), net return (Rs. 1,31,233.33) and benefit cost ratio (2.85) per hectare. Hence, it may be concluded that foliar application of ZnSO4@ 0.5 % either alone or
in combination with Borax @ 0.1 % not only to enhance flowering characters but also yield of cashew variety BPP- 8. So, foliar application of micro-nutrient was found to be better over growth regulators.

Effect of growth promoting substances on flowering behaviour of cashew cv. BPP- 8 grown in the coastal region of Odisha
Abstract
A trail was carried out at All India Coordinated Research Project on Cashew, (OUAT), Ranasinghpur,
Bhubaneswar, Odisha during the year 2016-17 to access the effect of growth promoting substances on
cashew cultivar BPP- 8. The experiment consisted of eight treatments of growth promoting substances
along with control. The treatments are T1- NAA @ 50 ppm, T2- GA3 @ 50 ppm, T3- Kinetin @ 50 ppm,
T4- ZnSO4 @ 0.5 %,T5- Borax @ 0.1 %, T6- ZnSO4 @ 0.5 % + Borax @ 0.1 %, T7- Seaweed extract @ 2
ml. L-1
, T8- Water spray (Control). Growth promoting substances were applied at three stages viz. preblooming stage, flowering stage and after fruit set except GA3 which was sprayed only once at preblooming stage. The result revealed significantly positive impact of growth promoting substances on
cashew. Foliar application of ZnSO4 @ 0.5 % recorded significantly higher number of hermaphrodite
flowers (66.33) and sex ratio (0.18).

2. Studies on growth promoting substances on physico-chemical parameters of cashew (Anacardium occidentale L.)
The present experiment entitled “studies on growth promoting substances
on physico-chemical parameter of cashew (Anacardium occidentale L.) var.
BPP- 8 (H 2/16)†was carried out at All India Coordinated Research Project
on Cashew, (OUAT), Ranasinghpur, Bhubaneswar, Odisha during the year
2016-17. The experiment consists of eight treatment i.e. T1- NAA @ 50
ppm, T2- GA3 @ 50 ppm, T3- Kinetin @ 50 ppm, T4- ZnSO4 @ 0.5 %, T5-
Borax @ 0.1 %, T6- ZnSO4 @ 0.5 % + Borax @ 0.1 %, T7- Seaweed
extract @ 2 ml. L-1
, T8- Water spray (Control). The plant treated with
ZnSO4 @ 0.5 % + Borax @ 0.1 % emerged as best treatment in terms of
nut length (3.38 cm), nut breadth (2.79 cm), nut weight (8.40 gm), kernel
weight (2.60) and number of nuts per kg (121.67). Whereas, ZnSO4 @ 0.5
% showed highest length (5.33 cm) and weight (65.37 gm) of cashew apple
and NAA had significant effect on quality parameters of cashew apple like
TSS (13.27), starch (11.01 %) and sugar content (12.24%).

3. Prospect of cashew cultivation in Odisha: A review
Abstract
Cashew (Anacardium occidentale L.) is a tropical tree introduced to India by Portuguese during 16th
century for the purpose of soil conservation and can be grown in waste land. Then onwards it’s become a
major cash earning crop for India and cashew nut is the most valuable processed nuts traded on the global
commodity markets. In Odisha most of the coastal regions occupied with cashew plantation but the
productivity of cashew in Odisha as well as India is too low. Generally, cashew grown areas of Odisha is
covered with seedling origin plants and no proper care and management has been taken out by the
farmers to get and to maximize the yield per unit areas. So, in this paper discussion has done about
benefits of cashew cultivation and to increase the productivity of cashew in our state. By use of good
quality planting materials, adoption scientific cultivation methodology, use of technology after all
awareness of cashew grower can increase production of cashew as well as strengthen the livelihood of
farmers.

Article on influence of bio-regulators on guava (Psidium guajava L.) cv. L-49 along with crop regulation by branch bending and shoot pruning under South-East conditions of Odisha
Abstract
The ‘apple of the tropics’ or ‘poormans apple’ is one of the most important fruit crops grown in India.
The guava fruit has gained a considerable prominence on account of its high food value, a pleasant
aroma, rich flavour and availability in the market at moderate prices (Bal and Dhaliwal, 2003). It is one
of the most important fruit in terms of area and production after mango, banana and citrus. It is a good
source of Vitamin C (260-300mg/100g of pulp) and highest fibre content 6.9%. Presently, the
productivity of guava is smaller than productive potential primarily due to traditional system of wider
planting and secondarily due to poor canopy management practices. The basic principle of crop
regulation is to manipulate the natural flowering and fruiting of guava plant in desired season of the year
that contribute to increased fruit yield, quality, profitability and sustainability of the environment by
reducing the use of the frequency of the pesticides. Shoot bending is one of the ways to produce better
quality fruits in the off-season.

EFFECT OF IBA ON VEGETATIVE PROPAGATION OF NERIUM OLEANDER ‘VARIEGATA’ THROUGH CUTTINGS
Abstract: An experiment was carried out at Horticulture Nursery, M.S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Paralakhemundi, Odisha during 2019-20. For the experiment sand was taken as rooting medium and experiment designed on Randomized Block Design (RBD) with 6 treatments and 4 replications. The treatments were T1- Control, T2- IBA @ 500ppm, T3- IBA@ 1000ppm, T4- IBA@1500ppm, T5- IBA@2000ppm and T6- 2500ppm. The results express positive response of IBA concentration towards rooting characteristics of Oleander. Application of IBA @ 2500ppm shows higher results on survival percentage, root length, root numbers, rooting percentage and fewer days taken for sprouting of cuttings.
