Yield And Quality

A field experiment was conducted in the Department of Agricultural Botany, Janta Mahavidiyalaya Ajeetmal, Auraiya (C. S. J. M. University, Kanpur) during 2014, to evaluate the effect of various levels of nitrogen on growth, yield and quality of fodder maize. 3 treatments were taken up (viz.,T1 75, T2 100 and T3 125 kg nitrogen ha-1 along with control (T0).Plant height, dry matter accumulations (t ha-1), forage yield (t ha-1) increased with increasing levels of nitrogen, while stem diameters (cm), leaf area (cm2), fresh weight (g), crude protein percent decreased with increasing levels of nitrogen.

Crop Variety

A field experiment was carried out during Kharif season of 2010 and 2011 to study the effect of different nutrients treatments on the productivity of rice. Application of NPK with FYM and Zn proved to be superior in recording the highest Photosynthetic rate and Super Oxide Dismutase. Although fertilizers are important for enhancing rice production but excess use of fertilizer cause deterioration of soil quality which ultimately affect crop productivity so it is required to investigate the physiological aspects of rice plant under integrated nutrients. When imbalanced fertilizers doses are given to the rice-wheat cropping system, they showed a considerable decline in crop productivity and soil fertility.

The Impact

Abstract Runoff and soil erosion are serious environmental issues in farmland management. In a field experiment in Xingmu, China, data from nine plots with different slopes and crops were collected, and the crops' leaf area index (LAI) used to represent the impact of vegetation on runoff and soil erosion. The results show that slope and crop both have significant effects on runoff and soil erosion, and that the LAI can indicate the effects of different crops.

A field experiment was conducted at the Horticulture Research Farm Department of Horticulture, J. V. College, Baraut, Bhagpat during the year 2011 with the cultiver “Arka Anamica” was done in Randomized Block Design (R.B.D) with three replication. The experiments consisted of 16 treatments viz. N1 (80:60:60) NPK (Kg.)/ha, N2 (60:40:40) NPK (Kg.)/ha, N3 (40:20:20) NPK (Kg.)/ha, B1 (Azotobacter) 7kg/ha, B2 (Phosphate Soluble Bacteria) 7kg /ha, B3 (Azotobacter + PSB) and B0 (Control). The Maximum results an different attributes viz. Plant Height (67.30 cm.), No. of leaves per plant (63.95), No. of green pod per branch (3.87), and Area of green pod (48.69 cm2), Days to 50 % germination (7.25) and Days to 50 % flowering (20.06) were recorded under the treatment B3, where as Azotobacter 7 kg/ha + Phosphate Soluble Bacteria 7 kg./ha. Compression to the treatment B1, where as Azotobacter 7 kg/ha and better results like, Number of branches per plant (4.58), leaf area (267.57 cm2), Number of green pod per plant (3.87), Fresh weight per green pod (8.11 gm.) and Green pod yield per plot (3382.56gm.) were recorded under the treatment B3 (Azotobacter 7kg/ha + PSB 7kg/ha), followed by N1 (80:60:60) NPK (Kg.)/ha and minimum results were found under the control.
