Dragon Fruit and Anjeer Fields

Dragon fruit and anjeer (fig) fields are a sight to behold. The vibrant hues of the dragon fruit plants and the lush greenery of the anjeer trees create a picturesque landscape. As you walk through the fields, you are greeted by the sweet aroma of the dragon fruit flowers and the earthy fragrance of the anjeer leaves. The dragon fruit plants stand tall with their succulent, red or white fruits hanging delicately from their branches. Meanwhile, the anjeer trees provide shade and a sense of tranquility with their sprawling branches and abundant figs. It is truly a magical experience to wander through these fields, appreciating the natural beauty and marveling at the abundance of these exotic fruits.

E. AICRP on Arid Zone Fruits

I. Agro-techniques

a. Ber

  1. Under nutritional trial of ber, application of 500 g N2, 500 g P2O5 and 50 g K2O in the month of July (except half dose of nitrogen which is to be applied in the month of November) was found effective for getting maximum fruit yield.

  2. Best method of ber propagation was standardized in which root stock prepared in polythene tubes and budded 100 days after seed sowing combined with defoliation at budding time gave maximum budded success.

  3. Under standardization of propagation technique in ber, sowing of seeds in situ and budding with desirable scion was found better than sowing in nursery beds, defoliation and budding after transplantation.

  4. Zizyphus rotundifolia was found most suitable root stock for cultivar Gola where it exhibited maximum plant spread, stem girth, fruit yield per plant as well as quality of fruits.

  5. Very light pruning i.e, at about 25 buds (after 8th secondary) proved as the best pruning method in ber.

  6. Application of Diuron (pre-emergence) followed by Glyphosate (Post–emergence) @ 2.0 Kg/ha was recommended to check weed population in ber orchard. Treatment also improved the plant growth and increased fruit yield /ha.

  7. Pre-harvest application of 750 ppm 2-chloroethylephosphonic acid (Ethephon) was found useful in inducing early maturity of ber fruits when sprayed at colour turning stage (about one week prior to the anticipated first harvest). The treatment also reduced the number of pickings from five to three.

  8. Sampling of immature young leaves at flowering stage was gave right indication of NPK status in the ber plant.

  9. Different ber orchards of Rajasthan situated in Bharatpur, Dholpur, Dausa, Jaipur, Karauli districts have been surveyed for nutritional status. Observations showed that the leaf samples collected from Bharatpur and nearby areas were higher in nitrogen, phosphorus, calcium and magnesium content. Potassium content was higher in leaf samples collected from Jaipur area. The soil samples were also showed the same trend.

  10. Use of mulches has been found beneficial in increasing fruit yield in ber. Black polythene and local grasses were equally effective as mulch material to conserve moisture in the soil and fruit yield per plant.

  11. Spraying of sulphluric acid (0.05%) was found most effective treatment in ameliorating the effect of frost followed by cycocel 250 ppm spray in ber.

  12. Zizyphus rotundifolia used as rootstock was performed better at high salinity level in the soil owing to its higher rates of net photosynthesis and transpiration, osmotic adjustment, chlorophyll retention restricted translocation of sodium from root to leaves as well as higher accumulation of potassium in the leaves.

b. Aonla

1. Patch budding during mid August was found most preferable for aonla propagation.

2. Application of pendimethalin (pre-emergence) followed by glyphosate (post-emergence) @ 2 kg a.i./ha applied at six-month interval was found most economical treatment than other treatments to control the weeds in aonla orchards.

c. Pomegranate

  1. Fruit cracking in pomegranate was reduced maximum with borax 0.2% followed by GA3 100 ppm. Yield data revealed that borax increased yield maximum over other treatments albeit application of GA3.

  2. Two foliar spray of ZnSo4 @ 0.06% at the time of flowering and fruit set during Mrig bahar was significantly increased yield in pomegranate cv. Ganesh.

  3. In sampling techniques for nutrient analysis, young leaves were found to contain the highest N, P, and K contents during February to July.

  4. Drip irrigation studies were conducted in cv. Ganesh. Maximum fruit yield was recorded with 60% evaporation replenishment.

d. Lasoda (Lehsua)

  1. Lasoda (Lehsua) fruits blanched by dipping in boiling water containing Magnesium oxide solution 4 g per litre for 5 minutes followed by de-stoning and given sulphitation treatment by soaking in potassium meta-bi-sulphite solution 1 g per litre. These treated fruits were dehydrated under solar drier to obtain best quality of dehydrated fruits with maximum returns.

II. Plant Protection

i. Insect & pest

Ber

i. IPM comprising digging of soil in the basin and mixing of 50g insecticidal dust and spray of Monocrotophos 0.05% at Initiation of monsoon followed by three sprays of Monocrotophos 0.03% starting from pea stage gave complete protection against insect pests of ber at Jobner.

ii. Minimum damage of ber stone weevil, Aubueus himalayan was found in foliar spray of carbaryl 0.1%, given just before fruit set. This treatment also recorded good population of honey bee (as post treatment) and better fruit set per cent in ber.

iii. Foliar spray of Azadirachtin 1% at 1 ml/liter water, just before fruit set and subsequently spray after three weeks was effectively control the ber stone weevil.

iv. Two foliar spray of NSKE 5% per liter water at 15 days interval starting from 50% fruit set was effectively control the ber fruit fly.

Aonla

i. Three foliar sprays of Cypermetharin (0.005%) or Endosulfan (0.05%) at the onset of monsoon at 15 days interval was found best treatment to control the stem capsule caterpillar in aonla at Jobner.

ii. Deshi aonla seedlings were found least susceptible against leaf midge. Whereas, var. NA 10 was found moderately susceptible and Chakaiya & NA-6 were found highly susceptible at Jobner.

iii. Aonla leaf gall midge was effectively control by the foliar spray of Endosulfan @ 0.07% starting from onset of the monsoon at Jobner.

iv. Studies on population dynamics of aonla leaf gall midge, Asphondylia phyllanthi showed that pest initiation starts in the month of March in field, hence it is right time for starting the insecticidal sprays against the pest.

v. In aonla, maximum damage of stem capsule caterpillar (Betousa stylophora) was found in NA-5, whereas, minimum in Deshi at Jobner conditions.

c. Pomegranate

i. Plugging of holes with mud and chemical spraying with Dichlorvos 0.08% or Monocrotophos 0.08% or Diamethoate 0.08% or Fenvulerate 0.04% or Carbaryl 0.1% or injection of these chemicals (5%) checked the damage of bark eating caterpillar in pomegranate at Jobner.

ii. Diseases

a. Ber

1. Under epidemiological studies it was found that ber powdery mildew initiation takes place in the month of October in Jobner conditions. Therefore, two prophylactic fungicidal sprays can be recommended at 15 days interval starting from October first fortnight.

2. Ber cultivar “Sev” was found resistant to ber powdery mildew.

3. Ber cultivars Noki, Tikadi, Thornless and ZG-3 were found resistant against Isariopsis leaf spot.

4. Weeds namely phyllanthus tratemus and Xanthium strumarrium were found collateral hosts of ber powdery mildew.

5. Three foliar sprays of Karathane EC (0.1%) at 15 days interval is recommended for control of ber powdery mildew. The prophylactic spray should be given just after initiation of the disease.

b. Aonla

1. Under epidemiological studies it was found that aonla rust disease initiation takes place in the month of August at Chomu (Jaipur) conditions. Therefore, the prophylactic fungicidal spray can be recommended in the last week of July.

2. Local aonla germplasm namely JA-3, JA-5 and JA-6 were found free from aonla rust.

3. On the basis of cost benefit ratio, four sprays of chlorothalonil (Kavach –75 WP) 0.2% at 15 days interval was found most effective to control the aonla rust followed by six sprays of chlorothalonil (0.2%) at 10 days interval.

4. The occurrence of dieback (Botryodiplodia theobromae) disease in aonla trees has been first reported in the state.

5. Dipping of aonla fruit in the solution of Azadirachtin leaf extract (5%) or Curcuma longa rhizome extract (5%) for 15 minutes was recommended for the control of blue mould rot and Aspergillus rot of aonla.

6. For integrated pest-disease management (IPDM) studies, two sprays of Azadirachtin 0.3% at 15 days interval in the month of April followed by two sprays of chlorothalonil 0.2% during august is recommended for control of aonla rust whereas, for managing leaf gall midge in aonla, two sprays of Azadirachtin 0.3% at 15 days interval during April followed by two sprays of Endosulfan (0.07%) in the month of august at 20 days interval is recommended.

7. New post –harvest fruit rot of aonla incited by Penicillium fallutanum reported as a new pathogen from this centre.

8. Four foliar sprays of chlorothalonil (0.2%) or Trichoderma (0.1%) + chlorothalonil (0.1%) are recommended for effective control of aonla rust. First prophylactic spray should be initiated in the first week of august. Subsequent three sprays are to be given immediately after the appearance of the disease at 15 days interval.

Bael

1. Under the study carried out to find out cause of wilting/ drying in bael plants Fusarium solani was found responsible for the root rot disease.
