With the availability of required inputs for intensive agriculture, the cropping system in Punjab state has undergone a paradigm shift, from a much diversified cropping pattern to a very specialized monocropped one. A study was undertaken in Bathinda district of Punjab State for mapping crop area, cropping pattern and finally long term changes in cropping pattern. Multi-year, multi-date, IRS LI...

Conducting research on monitoring contaminated fields by heavy metals is necessary in order to achieve sustainable agriculture, increase product quality and keep public health. This study was carried out using split plot experiment based on randomized complete blocks design with three replications during 2014-2015 in Shavor Agricultural Research Center in order to evaluate the effect of croppin...

Rice cropping systems not only characterize comprehensive utilization intensity of agricultural resources but also serve as the basis to enhance the provision services of agro-ecosystems. Yet, it is always affected by external factors, like agricultural policies.

Double direct-seeding for double rice cropping is a simplified, labor saving, and efficient cropping system to improve multiple-crop index and total rice production in central China. However, poor crop establishment of direct-seeded early rice due to chilling stress is the main obstacle to wide spread of this system. A series of experiments were conducted to unravel the effects of pre-sowing se...

This research was conducted to evaluate the trend of cadmium accumulation in wheat tissue and cultivated soil affected conventional cropping systems and different growth stage via split plot experiment based on randomized complete block design with three replications during 2014-2015 seasonal year. The main factor included two cropping systems (wheat-rice, fallow-wheat) and growth stage at thre...

succinea putris l. (mullousca: pulmonata:succineidae) were collected from the rice nurseries in mazandaran province during 2005. this species by feeding on rice seedlings leaves is another pest of growing rice in nursery. symptoms of early feeding are a row of circular continuous holes on lamina and eventually led to leave loss.the high density of snails in the nursery cause loss of large numbe...
