Some diseases are-
i. FIG MOSAIC-
· Yellow spots appears on foliage.
· Uniform distribution of spots on surface of leaves.
· Presence of irregular patches, mature lesions surrounded by a brown-red band.

BAJRA (Pennisetum glaucum)
Introduction-
· Also known as Pearl millet.
· Cultivated for grain as well as fodder purpose.
Found in which areas of country?
· Cultivated in arid region of Africa and Asia.

Soil conditions needed and Soil preparation-
· Well drained soil with mild salinity.
· pH of sil= 6-7.5
Rainfall and Irrigation required-
· Requires low annual rainfall.
· Since bajra is grown in rainfed areas therefore it hardly needs any irrigation.
· Avoid irrigation during flowering or grain filling stage.
Sowing-
· In middle or last week of july.
Seed rate-
· 4-5 kg/ha for drilling method
· 2.5-3 kg/ha for dibbling method
Intercrop/ Standing crop practices-
· WEEDING- Hand weeding is done mainly (Physical weeding) or with the application of some weedicides such as Atrazine (Chemical weeding).
· Pesticides- Some insecticide such as Carbofuran, Dimethoate can be used.
Harvest and Yield-
· When grain becomes hard and have sufficient moisture, it is harvested.
· It can be done by cutting of standing crop.
· It has a yield of 30-35 quintals per hectare (for irrigated crop).Major pests-
i. PEARL MILLET WHITE GRUB-
· Leaves turns yellow and wilts.
· Crown dries.
· Roots and base of shoots gets severely damaged.
MANAGEMENT-
· By their natural enemies such as Ground beetles, ants.
· Through seed treatment.
ii. SHOOT FLY-
· Attacks crops in seedlings as well as leaf stage.
· Causes chaffy grains in mature crop.
· Causes dead hearts in young plants.
MANAGEMENT-
· By their natural enemies such as spiders.
· Spraying should be done after 6 days of emergence of crop.
Some diseases are-
i. DOWNY MILDEW-
· Complete ear becomes a leafy structure.
· Pale and chlorotic streaks.
· Fungal growth occurs on upper and lower surface of leaves.
MANAGEMENT-
· Timely spraying of appropriate amount of fungicides.
· By the application of Cymoxanil.
· Elimination of moisture and humidity from the surrounding of plant.
ii. ERGOT-
· Cream to pink droplets of honeydew are seen on infected florets.
· Irregularly shaped sclerotia.
MANAGEMENT-
· By using fungicide named Bavistin.
· Use clean seeds.
· Use long crop rotation technique.
WALNUT (Juglans regia)
Introduction-
· Popularly known as Akhrot.
· Prevents cancer.
· Controls diabetes.
· Improves heart and brain health.
Found in which area of country?
· Mainly found in Mexico, Ukraine, China, USA, Turkey and Iran.

Soil conditions needed and Soil preparation-
· Well drained loamy or clay loamy soil is preferred.
· Soil should be rich in humus and lime.
· pH of soil= 6-7.5
Rainfall and Irrigation required-
· It requires annual rainfall of 800mm for its better growth and yield.
· Irrigation is done after transplanting the crops from nursery.
· Regular irrigation should be given.
· Avoid irrigation during rainy season.
· Drip irrigation is mainly done for appropriate use of water.
Sowing-
· Black walnut seeds are planted 2 inches deep in the month of September, October and November
Intercrop/ Standing crop practices-
· WEEDING- Mulching can be done, manual weeding can also prevent weeds in the field. By the use of appropriate chemical weedicides.
· PESTICIDES- Kaolin can be used.
Harvest and Yield-
· It is mainly harvested after 10-12 years of planting.
· Whereas grafted plants are harvested after 4-5 years of planting since early fruit bearing starts in grafted plants.
· A mature tree of walnut produces 125-150kg of nuts.
· Average yield = 40-50kg of nuts/ tree.Major pests-
i. CODLING MOTH-
· Its larvae feeds on kernel of walnut.
· Those nuts which gets damaged early falls from the tree, whereas those nuts that get damaged later on, remain on trees with their inedible kernels.
MANAGEMENT-
· By the application of various insecticides.
· Cutting out of damaged portions.
· Sanitation and fruits bagging can be done.
ii. WOODBORING BEETLE-
· Appearance of wood is ruined by the formation of holes on its surface.
