 दलहनी फसल अरहर में एकीकृत रोग प्रबंधन Pigeon pea is an important pulse crop and has major role in food and nutritional security because it is a rich source of protein, minerals and vitamins. The cultivated area and production of pigeonpea have recorded a steady positive growth in the past 50 years, but the mean national productivity has remained unchanged at around 700 kg/ha. To increase its productivity, breeders are trying to develop suitable varieties with subjective spread, growth, duration, disease and pest resistance under varied agro-climatic growing conditions.  Diseases are a continual problem and control measures must be planned for developing sustained production. Each condition that affects plant growth also affects the disease...

मक्का में जस्ता की कमी और निगमन Zinc is a micro-nutrient essential for the growth and development of plants, animals and humans.

Of all micro-nutrients, zinc is the most often deficient in corn production and most likely to elicit a yield response when applied as fertilizer. However, yield responses are only attainable when zinc is deficient and therefore limiting yield.  Role of Zinc in corn plant Synthesis (production) of growth hormones and proteins.

10 Major physiological disorders of palm and their management खजूर शुष्क और अर्द्ध शुष्क क्षेत्रों की बहुत महत्वपूर्ण बागवानी फसल है, जहाँ का तापमान 50 डिग्री सेल्सियस के ऊपर, पानी और जल की प्रकृति क्षारीय हो, वार्षिक वर्षा 200 मिमी. से कम हो और कोई अन्य व्यवसायिक फसल नहीं होती हो । अतः उन क्षेत्रों के लिए खजूर की फसल एक वरदान है, क्योंकि खजूर की खेती में लागत कम, उत्पादन अधिक और बाजार में मांग भी अधिक होती है। यह फसल इन क्षेत्रों की अर्थव्यवस्था और सामाजिक जीवन में केंद्रीय भूमिका निभाती है।  उत्तरी अफ्रीका और मध्य पूर्व एशिया के शुष्क क्षेत्रों में खजूर के फल एक प्रमुख खाध्य फल है। खजूर की...

कारगिल, लद्दाख क्षेत्र में कोडलि‍गं मोथ के प्रबंधन के लिए एक संभावित उपकरण - सामूहिक फंदा (मास ट्रैप)  Mass trapping is just as the name suggests, placement of a large number of traps in an area, which usually have a sticky cardboard bottom baited with pheromone lures. The lure mimics the scent of a female moth attracting male moths to the trap with the result preventing or delaying mating. Mass trapping requires a high density of traps in order to remove enough males to reduce insect damage. Mass trapping has been attempted for a variety of agricultural, orchard and forest pests on scales ranging from a few to thousands of hectares ....
