Traditional mulch material (farmyard manure) has long been used in agriculture. However, recent developments have also introduced the scientific community and farmers to advanced chemicals such as potassium polyacrylamide (KPAM), which revolutionised concept of soil water-holding capacity many compared with other materials being used. To compare effect different organic inorganic amendment unde...

such aabiotic stresses like water stress are some of the most important threats to the production of agricultural crops. it is almost very rare to find a place with no stress where plants can reach their potential yield. a water stress of 17 percent decrease yield, due to its effect upon fruit setting is notable. therefore, a study was conducted in bushehr agricultural research center (located ...

A comprehensive study on both the eco-physiological and productive response of potatoes to dynamic deficit irrigation is lacking. Therefore, aim was study, over two growing seasons potato cultivars—Arinda Timate, effects five regimes (I0–dry control, I1—irrigated I2—supply 100% maximum evapotranspiration—ETm from tuber initiation up 50% growth 0% ETm end growth, I3—supply I4—supply 75% growth) ...

The current study was carried out at the experimental farm of Rana Sugars Ltd., Buttar Seviyan, Amritsar, Punjab, India, to identify methods improve yield and quality ratoon sugarcane in potassium-deficient soils. treatments comprised two levels irrigation, resulting plants which either received sufficient water (I1) or were water-stressed (I2), four rates potassium (K) application: 0 (K1), 40 ...

introduction roselle (hibiscus sabdariffa l.) as a medicinal plant belongs to the malvacea family. their active ingredient increases under water stress. humic acid bacteria derived from humus and other natural resources have hormonal effects and can improve nutrient absorption to enhance performance especially under stress conditions . materials and methods this experiment was conducted in the ...

The experiment was carried out at Agronomy Field laboratory, Department of Agronomy and Agricultural Extension, university of Rajshahi, to study the effect of irrigation and sowing method on yield and yield attributes of mustard. The experiment consists of two factors i) irrigation viz. no irrigation (I0), one irrigation (I1)and two irrigations (I2) ii) sowing method viz. line sowing method (M1...

This study provides the first data on muscle activity patterns during active feeding in a larval anuran. Data regarding muscle function during gill irrigation and hyperexpiration are also provided. Electromyographic and kinematic data were recorded from six mandibular and hyoid muscles in unanesthetized, unrestrained larvae of Rana catesbeiana. Only three (hyoangularis, orbitohyoideus, anterior...

1 This publication was developed to provide a summary of information about common boll-feeding bugs (heteropteran pests), stress proper identification of these pests, and acquaint the reader with the recommended strategies for management of boll-feeding bugs in cotton. The first section of this publication emphasizes the recent importance of boll-feeding bugs in cotton and provides a brief disc...
