Abstract

Present study was planned to assess the nutritional evaluation of maize plant grown in spring and autumn seasons. For this purpose, a total of 277 (n=130 in spring and n=147 in autumn season) samples were collected from high maize-growing localities i.e. Kasur, Pakpattan, Okara, Burewala, Sahiwal, Lahore and Melsi. These samples were analyzed for different parameters such as dry matter (DM) and Crude protein (CP) etc. It was noticed that during spring season the values of dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF) and starch were significantly higher than autumn season values. On the other hand, crude protein (CP) was higher in maize grown in autumn season. Furthermore, dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF) and starch were low in autumn sampling than spring season. The evident difference showed that during autumn season, at the time of growing season, the seasonal conditions are tough which gradually become favorable from nutrients point of view. While the maize grown in spring season found suitable environment which gradually harshen at the time of harvest. Therefore, it is suggested to cut the spring-crop early in spring during the month of May-June to have better nutritional value.

巴基斯坦旁遮普春季和秋季种植的玉米植物饲料的营养评价

本研究拟对春秋两季玉米植株进行营养评价。为此，在Kasur、Pakpattan、Okara、Burewala、Sahiwal、Lahore和Melsi等玉米高生地共采集了277份样本(春季n=130份，秋季n=147份)。对样品进行干物质(DM)、粗蛋白质(CP)等参数分析。春季干物质(DM)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)和淀粉含量显著高于秋季。另一方面，秋季玉米的粗蛋白质含量较高。干物质、中性洗涤纤维、酸性洗涤纤维和淀粉含量秋季低于春季。明显的差异表明，在秋季，在生长季节，季节条件是艰苦的，从养分的角度来看，逐渐变得有利。而春季种植的玉米则在收获时逐渐找到了适宜的生长环境。因此，建议在5 - 6月的早春时节采收，以获得更好的营养价值。
