Lentil (Lens culinaris L.) is an important edible pulse crop. It is an important source of protein for human diet, plays a vital role as a rotational crop and enhances soil fertility. Sclerotium rolfsii causing collar rot disease on lentil crop is an important polyphagous pathogenic fungus causing substantial losses in quality and productivity (Punja and Grogan, 1988).

The strategies is made in such a way that product of one component should be the input for other enterprises with high degree of complimentary effects on each other. The information on AACS in a systematic way is presented here. An investigation was undertaken during 2010–20111 to 2014-15 to assess the agro-economic potentiality of ten promising high-value crops alternative arable cropping systems in order to diversify the cereal–cereal based rotations and owning maximum profitability in subtropical climatic condition of western Uttar Pradesh production systems...

Maize is a heavy nutrient feeder crop but over and inappropriate fertilization provides lesser yield than the genetic yield potential, lower profits and deterioration in soil health therefore, a new fertilizer recommendation approach, Nutrient Expert (NE) for hybrid maize was evaluated against farmers fertilizer practice (FFP) in three years maize-wheat rotation. Results revealed that nutrient expert-decision support system based nutrient management gave higher yield, nutrient uptake and profits and sustained soil properties over other practices.

A long-term experiment was conducted to evaluate the effect of integrated use of organic and inorganic sources of nutrients on soil quality and its relation to rice yield under Rice – rice crop rotation. A field experiment was conducted during rabi, 2015 and karif, 2016 at Regional Agricultural Research Station, Jagtial (India) on an ongoing long term (16 years) experiment which was initiated in kharif, 2000.

Conventional tillage practices may adversely affect long-term soil productivity due to erosion and loss of organic matter in soils. Sustainable soil management can be practiced through conservation tillage (including no-tillage), high crop residue return, and crop rotation.

In the present study, diagnostic analysis of the irrigation system was done and a rotational water allocation plan on the basis of ET requirement of crops was developed for a command area. The crop water requirements for the major Rabi crops viz. wheat, gram and barley were computed by Penman-Monteith method using computer program ‘CROPWAT’ and these were used in the development of rotational water allocation plan. This system leads to increased credibility and reliability, enhanced equity in water distribution, proper utilization of water resources and increased water use efficiency.

Rice-wheat (Oryza sativa L.-Triticum aestivum L.) rotation is the major production system in Asia, covering about 18 million ha. Continuous and conventional RWC system practice has witnessed a significant slowdown in the yield growth rate. The sustainability of this important cropping system is at risk due to second-generation problems (low fertility status, multiple nutrient deficiencies, and imbalanced use of fertilizers, ground water depletion at faster rate, soil salinization, and inadequate system diversity).

Presence of diverse weed flora during critical period of crop-weed competition, is one of the major obstacles in conservation agriculture that reduces which can reduce the crop yield appreciably significantly. During critical period of crop-weed competition, chemical method of weed control is by far the most preferred way to minimize the weed infestation of weeds, farmers are mostly relying on chemical methods of weed management.

Krishi Vigyan Kendra, Bhiwani had conducted Front Line Demonstration (FLD) at the farmers’ field in the villages of districts Bhiwani & Dadri during 2015-16, 2016-17 and 2017-18. The critical inputs were identified in existing production technology through meetings & discussions with farmers. The farming situation of demonstration fields was irrigated, low in nitrogen, medium in phosphorus and potash and the soil was sandy loam. The crop rotation was pearl millet-mustard, cluster bean-mustard and mung bean-mustard.

Rotation of rice-wheat cropping system is most popular in India due to its high productivity; however, these crops are highly infested by the varied weeds, thus farmers use various herbicides for their control. Resulting, this rotation consumes a large quantity of herbicides, which has resulted in severe problems like environmental and human health hazards; development of herbicide resistance in weeds etc.

The study was carried out during 2013-14 in Meerut district of Uttar Pradesh state to focus on the sugarcane growers regarding impact of knowledge on adoption level of IPM practices. The 80 contact farmers were selected as respondents. The study revealed that the maximum knowledge gap was found to be existing in previous crop residues, crop rotation, hand picking of the insect and their destruction, hot air and water treatment, light and pheromone trap, microbial control, use of natural enemies, resistant varieties, biopesticides/ bio-agents, application and dose of different pest etc.
