It is an inclusive peer reviewed interdisciplinary journal aimed to advance the interaction of plant and environmental science for the betterment of all stake holders of the society, present and in the future. IJPE has been founded by a team of botanists and environmental scientists to accelerate the gait of scientific advancement and establishing its value. We publish the research in environmental botany and allied fields aimed to benefit the scientific society, academicians and policy makers.</p> <p>IJPE welcomes high quality submissions on all aspects of environmental contamination or air, water and land, bioremediation strategies for pollutants, bio-indication, eco-system dynamics and forest degradation, environment and biodiversity conservation, sustainable agriculture, global change impacts on plants. Responses of plants to abiotic stresses (salinity, heavy metals, drought, temperature stress, flooding etc.) and biotic stress (plant insect, plant microbe interaction etc.), plant environmental interaction at morphology, physiology and molecular levels. Submitted manuscripts are evaluated on the basis of methodological rigor and high ethical standards besides, perceived novelty.</p> <p>IJPE intends publication under different categories, viz., original research papers, short research communications, research update/ mini reviews, commentaries. The original research articles, mini reviews/ research update shall not exceed 10 printed pages. The articles published under the short communication category are expected to contain path breaking researches requiring urgent publication. The length of such articles shall be restricted to five printed pages.</p> </div> </div> <div class="row">&nbsp;</div> MRI Publication Pvt.

In India, maize is the third most important food crop after rice and wheat. A manually operated punch planter for corn was designed and developed to improve planting efficiency and reduce drudgery involved in manual planting method. The idea is to put the seed in soil by punching holes in the soil and drops the seeds in them. The field capacity of manually operated punch planter was found to be 0.091 ha h^-1 with the field efficiency of 80.33% at an average working speed of 1.58 km h^-1. At high operator speed (1.76 km h⁻¹) and large seed metering cell size (12 mm), the missing index increases, whereas it decreases under high hopper fill level (100%) and low operator speed (1.4 km h⁻¹) due to improved seed flow consistency. The multiple index rises with larger cell size (11 to 12 mm) and higher speed (1.40 to 1.76 km h⁻¹), but drops to its lowest when both operator speed and hopper fill level are reduced. Increasing seed cell size from 10 to 12 mm enhances the quality feed index, while increasing operating speed from 1.4 to 1.76 km h⁻¹ reduces it. The hourly cost of operation and cost of operation per ha were computed to be Rs 33.20 hr^-1 and Rs 364.83 ha^-1 respectively using manually operated punch planter. The cost of operation for traditional method of sowing was Rs.2500 ha^-1.</p> M.
